Objective Ambiguity

Objective ambiguity is not only possible but common. Indeed its denial is responsible for much of what is wrong with the world.

This is what I would call an interpretive principle. I think it is characteristic of facts as well.

We only make judgments about ambiguity in contrast with things more definite. But perhaps the converse could be said as well, and we only make judgments about definiteness in contrast with things more ambiguous. I am inclined to think that the absolute poles on this spectrum — absolute definiteness and absolute indefiniteness — are never found in what I still want to call the real world.

What we want to say objectivity is seems to be one of the things that could always be more pondered. But I want to say that there are quite meaningful things we can say about it, and one of these is that objectivity properly said must include an appropriate recognition of objective ambiguity.

There is a human-sized definiteness that is not absolute, but remains morally compelling. Definiteness itself does not have razor-sharp edges. We adhere to it in a broad way and not in an absolutist way, and that is for the better. Broad adherence to anything is better than absolutist adherence, which overdoes things and is not responsive to nuance.

Sensitivity to nuance is a delicate thing, but it is the better thing. When I recently wrote about “kindly objectivity”, one thing that slipped out spontaneously was that the ethical sense of objectivity is characterized not only from an angle of fairness, or objectivity as fairness and lack of bias in interpreting things and people, but also as a kind of magnanimity. As the word “magnanimity” wrote itself into the text, I paused and wondered where that came from? But the more I think about it, the more I think it is true. To be magnanimous is to be more than fair, whereas normal biases as well as extraordinary ones cause people to be less than fair. It is to display the “wise charity” by which Leibniz characterized justice.

As we reach toward our best judgments of things and people, we display magnanimity and wise charity. When we get to the level of nuance, we get closer to reality. Hard edges become fractally ramified, but at the same time substantiality, “thickness”, conditional definiteness, reality begin to emerge of themselves out of the shimmering. Reciprocity lifts itself by the bootstraps. We and the other can find coexistence and emergent truth together.

Poetically speaking, this has great relevance to the kind of second-order historical interpretation I call “historiographical”.

Of Relatives and Realities

Charles Pierce (1839-1914) was the founder of American pragmatism. He is considered by some to be the greatest American philosopher. He largely originated the mathematical theory of relations (the “relatives” of the title here). Along with Frege, he is regarded as a co-founder of mathematical logic. Along with Saussure, he is considered a co-founder of semiotics.

Pierce had a keen interest in the philosophy of science, and particularly in the idea of evolution. But unlike most philosophers of science, he was also interested in Kant and Hegel. Moreover, he had a very unusual familiarity with medieval logic. Like Leibniz, he only published a tiny fraction of what he wrote.

Pierce thought it was very important to defend a realist position, and to criticize the nominalism that he saw as pervasive in the modern world. John Boler’s Charles Pierce and Scholastic Realism: A Study of Pierce’s Relation to John Duns Scotus (1963) focuses on this angle. He documents Pierce’s engagement with a narrow but important slice of the work of Scotus, centered on issues of realism and nominalism. A reading of Boler’s work will help to get a little deeper into Pierce’s thought. This will be a lengthy one-off.

Boler is aware of the hazards of writing about “isms”. He notes, however, that since Pierce himself dwells extensively on such terms, they will be unavoidable in understanding his thought.

“In its technical form in Pierce, pragmatism holds that the meaning of a statement consists in the truth of a conditional proposition stating what would happen as a result of certain tests. Two points are of special import here: that apparently simple conceptions like hardness are at bottom conditional in form; and that such conceptions relate not so much to what does happen in any one test, but to what would happen in response to a certain type of test” (Boler, pp. 12-13, citations omitted).

The reference to tests recalls Pierce’s interest in science, but what is essential here is the broader point that every assertion should be understood as shorthand for the assertion of one or more conditionals, even when its surface grammar is unconditional or categorical.

In a move that is ancestral to Brandom’s inferentialism and emphasis on the constitutive role of counterfactual robustness and subjunctive constructions, Pierce explains ordinary properties of things as condensed or hypostasized representations of if-then conditionals. This proto-inferentialism is central to Pierce’s conception of what reality is.

The other key aspect of reality for Pierce is clarified by focusing on the notion of constraint that such conditionals imply. This could be seen as ancestral to Brandom’s work on modality. It is reflected in the concern with what would happen if this or that.

“We find, says Pierce, that our opinions are constrained; there is, therefore, something that ‘influences our thoughts and is not created by them’: this is ‘the real’, the thing ‘independent of how we think it’. But problems arise if we hold that the real is that which influences our sensations, which in turn influence our thoughts…. Such problems disappear, according to Pierce, if reality is taken not as the source or stimulus of the knowledge process, but as its goal or completion” (pp. 14-15).

In the mid-20th century, the dominant philosophy of science was logical empiricism, which explicitly advocated a rigidly foundationalist view of reality as the source of knowledge. Since then things have turned again, and there is more diversity of opinion.

In this notion of reality as the goal of knowledge and not its source, there is an important partial convergence with Aristotle’s insistence in the Metaphysics on the primacy of the “final” cause. Aristotle’s own view of this was largely covered up by the Latin creationist adaptations of his work that took their bearings from Avicenna. The convergence of Pierce with Aristotle is only partial, because Pierce focuses on the temporal working out of processes of evolution, in contrast to Aristotle’s omnitemporal that for the sake of which.

There is a similar partial convergence and difference between Pierce and Aristotle with respect to the meaning of the primacy of actuality. In Pierce, actuality is understood in the modern way, in terms of present facts, though he understands evolution in terms of progress toward the better. (Aristotle and Hegel more emphasize a normative meaning of actuality, which may be at odds with present facts.)

“If on the face of it Pierce’s conception of reality seems a little odd, we might consider an oversimplified application in scientific inquiry. It may be, for example, that Copernicus got the idea for his hypothesis when he was looking at things from a moving platform. But the ‘objectivity’ of his theory is not validated by tracing it to some such suggestion; it is validated by checking the results of, among other things, his predictions. In general, a scientific hypothesis is not accepted because of where it came from but because of where it leads” (p. 15).

This also illustrates Pierce’s non-foundationalism.

“Pierce eventually comes to define reality as what will be thought in the ultimate opinion of the community” (ibid).

The “opinion of the community” is here subject to a kind of historical teleology of progress. This is the optimistic view that better ideas will prevail, given enough time. Brandom has argued that Hegel’s account of mutual recognition — which was not well-known in Pierce’s time — is a substantial improvement over Pierce’s ideal of eventual community consensus.

“Nominalists sometimes contend that a general is just a ‘word’, a fiction created by the mind as a convenience for talking about the world. Pierce is ready to grant that a general is of the nature of a word, but he points out that on his definition of reality this does not in any way prevent a general from being real” (p. 16).

Pierce seems to prefer the term “general” to the more common “universal” in logic. Either way, it means not something that applies to all things, but something that applies to many things.

Boler quotes Pierce, “[The great realists] showed that the general is not capable of full actualization in the world of action and reaction but is of the nature of what is thought, but that our thinking only apprehends and does not create thought, and that thought may and does as much govern outward things as it does our thinking” (ibid, brackets in original).

“How did pragmatism manage to get involved in this sort of thing? The clue to that lies with Pierce’s notion of the ‘would be’, which makes of the pragmatist a realist of an extreme sort. A character — hardness, say — does not consist in the actual responses to actual tests; as we shall see, Pierce criticizes his own early formulations of the pragmatic maxim for suggestion that it does. Hardness is something general, involving a relation of a type of test to a type of response. What is more, Pierce is not just denying that the would-be is the same as a totality of actualities; the very fact that a character is a would-be indicates that it has a different mode of being from that of actual events. The theory also involves the notion of really active (general) principles, which govern actual events” (p. 17).

What makes Pierce’s realism “extreme” is his emphasis on the real character not only of higher-order things, but also of higher-order relations. Pierce thinks of reality as not only saying something about what is, but also about what would be, under a broad range of alternate possibilities. Pragmatism in his eyes looks not only at present facts, but at what would be. Pierce argues that scientific laws already fit this model, but he wants to extend it to ordinary life as well.

“The reader who is scandalized that pragmatism should be mixed up with metaphysical questions might look at [citations to Pierce’s Collected Papers], where pragmatism is said to be ‘closely associated with Hegelian absolute idealism’ and with scholastic realism” (p. 17n).

[quote from Pierce:] “In calling himself a Scotist, the writer does not mean that he is going back to the general views of 600 years back; he merely means that the point of metaphysics upon which Scotus chiefly insisted and which has passed out of mind, is a very important point, inseparably bound up with the most important point to be insisted upon today” (p. 19).

That is to say, Pierce’s interest in Scotus is focused on the issue of realism and nominalism.

[Pierce again:] “But though the question of realism and nominalism has its roots in the technicalities of logic, its branches reach out about our life” (quoted, ibid).

Pierce says modern philosophy has been swept by a “tidal wave of nominalism” (quoted, p. 20).

Boler writes that in the Renaissance, “In the struggle for control of the universities, the humanists sided with the followers of Ockham in an attempt to overthrow the Dunces [Scotists], who were then in power. As a political favor, but with little concern for or understanding of the real issues involved, the humanists championed nominalism…. But if nominalism was misbegotten, realism on its own side was badly defended. The narrow, rationalistic anti-empiricism of the Dunces made the position unpalatable to those occupied with the growth of the new sciences…. Pierce will have to correct misinterpretations of the earlier controversy” (ibid).

[Pierce:] “The nominalist Weltanschauung [worldview] has become incorporated into what I will venture to call the very flesh and blood of the average modern mind” (quoted, p. 20n).

[Pierce:] “[I]t is proper to look beyond the letter [of scholastic formulations] to the spirit of it” (quoted, ibid).

Boler says “The most common and striking argument that the scholastic realists advanced for their position was the necessity of justifying scientific knowledge. Science, as Aristotle had said, deals with generals; and if science is true of the real world, the objects of scientific conceptions must somehow be real” (ibid).

Indeed Aristotle holds that knowledge in the strong sense applies only to universals. Of individuals we have only acquaintance and practical judgment.

[Pierce:] “Still it remains true that I do know that the stone will drop, as a fact, as soon as I let go of my hold. If I truly know anything, that which I know must be real” (quoted, p. 22).

[Boler:] “Pierce then explains that he can make such a prediction because he knows what kind of thing he is dealing with…. What interests him, however, is how this uniformity is different from that, say, of a run of sixes with honest dice” (ibid).

The run of sixes is only a repeated fact. Facts alone tell us nothing of what would be if the facts were different. In Aristotelian terms, most facts are called accidental. What is in a factual sense not only does not tell us what ought to be, it does not tell us what would be, independent of current particulars.

“After all, one need only see that every proposition contains a predicate in order to realize that our thinking is characterized by the use of generals; but that does not yet touch the issues dividing the nominalist and realist” (p. 24).

The very possibility of thought as distinct from opinion depends on judgments about the applicability of universals. This extends also to any kind of art or craft or practical know-how.

“Although the cook must handle particular apples, her indifference to individual apples indicates that what she wants is an apple and not a this” (p. 25).

If we were completely without universals, there could be no meaningful saying. Everything would only be this — and thus indistinguishable from anything else. We would be reduced to a completely inarticulate pointing.

“Pierce does not think that you can find generals in the sense that an archaeologist finds vases” (ibid).

No universal and no reality is simply there to be found, or immediately given. Reality as a distinguishing criterion is bound up with being able to say something about what would be under alternative conditions.

“As a matter of fact, Pierce feels that the realist position has been misunderstood because of a nominalistic prejudice that whatever is real must have the same mode of reality as all other real things” (ibid).

For a consistent nominalist, there would only be brute fact.

“Pierce insists that no great realist of the thirteenth or fourteenth century ever held that a general was ‘what we in English call a thing’. This is why he denies that the controversy in the middle ages had ‘anything to do with Platonic ideas’ ” (p. 26).

I like to rehabilitate the word “thing”. To be real, or to be a thing, is to be polymorphic, to be a subject of what would-be, and to have a less-than-numerical unity. In contrast, to be an object in the Scotist sense is to have numerical unity.

A strictly numerical unity or identity is always artificial. No idea is an object. People are like ideas, and not like objects.

He quotes Pierce again, “Let the artificers of such false inductions dare to set up predictions upon them, and the first blast of nature’s verity will bring them down, houses of cards that they are” (p. 27).

Insofar as words in a language express differences in the world, they are in fact not arbitrary in the way that proper names are. “Nominalism” treats words in general as mere names.

Boler continues, “Now, what is the difference between the group of things called Harry and the group of things called gold?” (ibid). “Now we take some of the things called Harry (the cat, an old rubber stopper, and a bar of soap), and we find that they all float in water. The next thing called Harry that we select may float in water, but we would bet on it about as we would on a run of sixes with dice” (p. 28).

Names are truly arbitrary, as the list of things called Harry illustrates. But the property of floating in water is not indifferent. We can use it as a “test” to distinguish things, which is just to say that it is a counterfactual, a would-be, and thus a meaningful basis of classification.

“If this regularity is due to the scientist’s giving the same name to similar objects, the question at best misses the point. What Pierce finds important is precisely the original similarity…. The problem still remains why the same term was applied to certain things” (p. 29).

“Pierce says of Ockham: ‘He allows that things without the mind are similar, but this similarity consists merely in the fact that the mind can abstract one notion from the contemplation of them. A resemblance, therefore, consists solely in the property of the mind by which it naturally imposes one mental sign upon the resembling things’ ” (pp. 29-30).

The situation resembles that of Aristotle’s critique of the sophist Protagoras, who claimed that “Man is the measure of all things”.

On the dropping of the stone, Pierce says the nominalist “may admit that there is in the events themselves an agreement consisting in the uniformity with which all stones dropped from the hand fall to the ground, but if he admits that there is anything at all, except the mere fact that they happen to do so, that should in any sense determine the different stones to fall every time they are dropped, he ceases to be a good nominalist and becomes a medieval realist” (p. 30).

Pierce again: “The man who takes the [nominalist] position ought to admit no general law as really operative…. He ought to abstain from all prediction” (ibid, ellipses and brackets in original).

And again, “My argument to show that law is reality and not figment — is in nature independently of any connivance of ours — is that predictions are verified” (ibid).

Yet again, “for if there was any reason for it, and they really dropped, there was a real reason, that is, a real general” (p. 31).

Back to Boler, “He does not think that the nominalist wants to deny scientific prediction, but he objects strenuously that nominalism does not explain it” (p. 32).

I previously presented Bertrand Russell’s critique of the modern notion of (efficient) cause in a positive light, because it was a critique of that notion of cause. But by Pierce’s lights, Russell would be a nominalist who fails to produce real explanations.

“While the realist bases his stand on the objective reality of our general conceptions, the nominalist bases his arguments on the independent reality of things…. Pierce feels that the good reasons for this view are distorted by its overemphasis, but that these can be preserved if the real is taken as the normal term or goal of our mental processes: that is, if we hold that our mental activity leads into the real world rather than away from it…. That is to say, whether he can refer the theory to Kant or not, Pierce continues to defend the idea that reality must be that which draws our opinions and not that which triggers them” (pp. 34-35).

While the nominalist may appeal to what Aristotle calls independent things, it now seems to me that she is not entitled to this. “Independent”, “reality”, and “things” all depend on the general and the would-be.

I really like this idea that reality is something we move toward, rather than something we proceed from.

“However much we may have to go into the technicalities of logic and grammar, we should not forget Pierce’s insistence that the nominalist-realist controversy is about real things…. The medieval realist was interested in an objective ground for general conceptions, while the modern nominalist wants to stress that the ‘thing’ exists apart from the mind…. [A] realist need not hold that all conceptions involve a real (that is, objective) generality, or that any universal is a ‘thing’…. [A] proper definition of reality is essential to any adequate solution of the problem” (p. 36).

“Broadly speaking, the scholastics held that only individual things (what they called ‘supposits’) exist. But these supposits have an intelligible structure (what the scholastics called a ‘nature’), which is not simply identical with the supposit as an individual. When a carpenter makes a bed, it is possible for him to have given the same structure to another thing. When someone looks at the bed, he sees that it could have been made with other materials — or better, he realizes that there could be other beds. It does not seem unreasonable to say, then, that it is the same structure, or nature, that is (1) in the mind of the maker, (2) in the bed, and (3) in the mind of the viewer” (p. 39).

“Notice, however, that while any and every bed will have a certain structure, the structure is not identical with any individual bed or group of beds; the structure is a sort of plan, whereas this or that bed is an execution or instance of the plan. In the world of supposits, however, we do not find plans existing alongside the instances of those plans” (ibid).

Structures and plans are higher-order things, not reducible to immediate particulars.

“First intention is thought about the real world; second intention is thought about first intention. Notice that first and second intentional concepts are equally mental. The objects of first intentional concepts, however, are real things, while the objects of second intentions are the first intentional concepts themselves. Thus although first intentional concepts are, in a sense, entia rationis [beings of reason], they have real things for their objects. Second intention can be defined, then, as having for its objects only entia rationis” (p. 43).

Here again we see the Avicennan notion of first and second intentions. This formulation makes it particularly clear that “second” intentions are second-order intentions — that is, intentions with regard to other intentions. Avicenna may have been the first to explicitly talk about second-order things.

“It should be clear even from the way Scotus states the problem that he does not intend to treat nature as another ‘thing’ (like Socrates, Plato, and the line)…. Scotus maintains that Socrates and Plato are ‘numerically distinct’, and consequently if they have the same nature, that nature must have a ‘less than numerical unity’ ” (p. 47).

I hold that anything real must have “less than numerical unity”, and I think this is an implicit assumption in Plato and Aristotle. Oddly enough, it is the neoplatonic enthusiasm for the One that led to more explicit examination of all the ways in which everything else is not a pure Unity.

“If it were maintained that this lesser unity is a contribution of the mind, and that the only real difference was the numerical one, it would follow that our scientific conceptions would not give us information about the real world…. I think that Pierce is making the same point when he says that the nominalist makes the real world to be an unknowable thing-in-itself” (p. 48).

Knowledge involves the ability to meaningfully generalize about the real world. It is exact, “numerical” identity that is artificial. Numerical identity is a valid concept in mathematics, but that is about the extent of it. Any kind of substance or essence or reality has a “thickness” that is mutually exclusive with the razor-thin, absolutist character of numerical identity.

“By a nature’s lesser unity Scotus does not mean something having the viscosity of taffy; the nature is not spread out in a physicalistic sense. As a matter of fact, he emphasizes that the so-called common nature is real in one object and not in two. The word ‘common’, then, may be misleading. Actually, Socrates has a Common Nature even if he is the only only man existing, for he is still a man and not manness itself. The Common Nature lacks a numerical unity precisely because it can be real without being determined to exist in any one thing. Although individuated in any existent thing — in Socrates, the nature is his in the sense of being this nature rather than that — the nature itself is indeterminate with respect to this thing and that” (p. 50).

“Such abstractions, however, should not be confused with second intention; for Scotus, this would be confusing metaphysics with logic…. However much an abstraction of this sort is a construction of the mind, it is a construction done with an eye on the real object. In second intention, ‘predicate’ would refer to ‘being a man’ without reference to any object beyond that predicate itself. In short, metaphysics is like logic in that its objects are abstractions of a second order; but it is like physics because its objects are real” (p. 61).

The common nature is thus sharply distinguished from a second intention. Avicennan intentions all have a psychological aspect, which Husserl criticized in Brentano’s revival of intentionality.

“As we shall see, Pierce gives a special status to some things ordinarily called individuals — notably the human person. Ultimately, such individuals are for Pierce living laws and thus essentially general” (p. 64).

What are commonly called individuals have a kind of streaming continuity that is neither numerical nor absolute. It is not the identity of individuals that makes them precious, but rather their differentiated and “less than numerically identical” essence.

“New developments in logic, Pierce feels, make the whole question of universals easier to express and to solve. Abstractions like humanity turn out to be simple forms — the limiting cases — in a general process whereby relations are treated as things (hypostasized) in order to serve as the terms for higher order relations. Pragmatism shows that scientific formulas take the form of such relations. When successful prediction indicates that these formulas are not fictions, they are called laws. Laws are manifested in things as real powers, or, in pragmatic terms, as real ‘would-be’s’ ” (pp. 65-66).

What common sense regards as individual terms or things turn out to be hypostasized (or as I like to say, shorthand for) relations. This makes excellent sense.

The “new developments” Pierce refers to are the explicit formulation of higher-order concepts.

Boler quotes Pierce, “[Logic] is the science of the necessary laws of thought, or, still better, (thought always taking place by means of signs), it is a general semiotic, treating not merely of truth, but also of the general conditions of signs being signs (which Duns Scotus called grammatica speculativa), also of the laws of the evolution of thought … which I content myself with inaccurately calling objective logic, because that conveys the correct idea that it is like Hegel’s logic” (p. 68).

“Pierce considers the basic logical elements to be the term, proposition, and argument. Of these, the argument is not only the most important but the most fundamental form. It is not, strictly speaking, composed of propositions in turn composed of terms; on the contrary, insofar as propositions can stand alone, they are implicit arguments, while terms are implicit propositions” (p. 69).

I am delighted to read this. Higher-order things come first, and that is why we cannot be foundationalist.

“In the proposition ‘Socrates is a man’, the predicate is ‘is a man’, a form that Pierce calls a rhema or a rheme. The logical subject of a proposition is what is placed in the blank space of a rhema to make a proposition. Of course the logical and grammatical subjects will not always coincide; in the example ‘Anthony gave a ring to Cleopatra‘, the underlined words are the logical subjects — a reasonable enough position which leads Pierce to frequent attacks upon the status of the common noun according to grammarians. Pierce brings grammar into line with logic by taking the basic grammatical forms as subject and verb, the subject being a demonstrative or something that can take its place, adjectives and common nouns being parts of the verb” (ibid).

Pierce thinks in terms of n-ary relations. Nouns are part of the verb. The demonstrative subject he recommends would be a generic “this”, a “free” variable having in itself no description or properties. This would bring grammar into line with the syntax of expressions in predicate logics, where propositions begin with “For all x”, or “There exists x”, and all the differentiation is grouped under the predicate.

“In speaking of the rhema, Pierce says it is obtained by erasing the logical subject(s) of a proposition, which shows perhaps as well as anything why the term is a derived form rather than a building block for propositions. That the proposition itself is an implicit argument requires a more complicated explanation — one involving Pierce’s contention that the copula is illative” (pp. 69-70).

In traditional logic, where a proposition has the surface grammar “A is B”, the “is” was called the copula. When Pierce says the copula is really illative, he means that what is logically meant by the surface grammar “A is B” is the conditional “If A(x), then B(x)”.

“First of all, Pierce denies that the copula is ‘is’, holding instead that ‘is’ is a part of the predicate. Still, he insists that a proposition cannot adequately be treated in terms of subject and predicate alone: for ‘composition is itself a triadic relationship, between two (or more) components and the composite whole’. Second, Pierce denies that the link between subject and predicate is identity, for he considers identity to be in reality only another general predicate. And finally, he affirms that the link, that is, the copula, is a form called consequence” (p. 70).

“Is” is part of the predicate. Identity is only another general predicate. Logic is built by elaboration of the notions of composition and consequence. The claim that composition is “triadic” goes along with this, and may turn out to help explain what Pierce means by “thirdness”.

“Pierce holds that the relation of premise(s) to conclusion is the same as that of antecedent to consequent. Consequence, then, is the prototype of argument; it is the ‘one primary and fundamental logical relation, that of illation, expressed by ergo [therefore]’. Note particularly that the consequence is the relation of consequent to antecedent, not just a consequent and an antecedent. An argument is somehow more than just its premises and conclusion, just as a proposition is more than its terms. Pierce tells us that a proposition is an assertion or predication of a predicate of a subject. Consequence, in which the copula is explicit, is the basic (what might be called the ‘normal’ predicational and inferential form” (ibid).

The idea that logical consequence is a relation has been generally accepted by later logicians. Consequence relation is now a standard term in advanced studies of logic. It specifies what follows from what in a given logic.

On the other hand, Pierce’s insight that there is or should be exactly one fundamental logical relation in a logic — consequence, or whatever we may call it — was not reflected in what came to be standard 20th-century presentations of logic. There has been a great deal of advanced work in several fields that could be seen as carrying forward the kind of unification that Pierce envisioned. But it has mostly used function-like constructs as basic, rather than relational ones. And it is still not mainstream.

“For Pierce, then, predication is essentially a form of consequence. We might note in passing two rather important effects of this doctrine. First, even the perceptual judgment is but a limiting case of hypothetical inference. Second, categorical propositions in their basic (or normal) form are, without exception, conditionals. The latter point in particular has a bearing on Pierce’s pragmatism” (p. 71).

These are all claims that I have made in the context of thinking mathematically about Aristotelian logic, without being aware of the precedent in Pierce. (See Aristotelian Propositions; Searching for a Middle Term; Syllogism; Predication.)

“We must now determine what Pierce means by calling the rheme a ‘relative’, for it is in terms of relatives that he will ultimately explain the generality of the predicate. A relative, he says, ‘is the equivalent of a word or phrase which either as it is [a complete relative] or else when the verb “is” is attached [a nominal relative] becomes a sentence with some number of proper names left blank’…. Pierce reserved ‘relation’ to indicate a relationship said to be true of one of the objects (usually the noun-subject), the others not being considered” (p. 73, brackets in original).

In more standard terminology, Pierce’s “relative” is an n-ary relation, like the fundamental construct used in a relational database. He avoids the term “relation” here because the Latin relatio was used to translate Aristotle’s category of pros ti or “toward what”, which resembles the way he does use “relation”.

“In treating the order and independence of relatives, Pierce finds that a triad cannot be reduced to dyads nor a dyad to monads. He does discover, however, that all relatives higher than triads can be reduced to triads” (ibid).

The same is true in algebra and physics — all the fundamental characteristics of higher-order equations can be understood in terms of the behaviors of second-order equations. And the classic laws of physics are mainly second-order differential equations. Second-order things are “triadic” in Pierce’s sense.

“If categorical propositions are virtual hypotheticals, it might be that all monadic predicates are virtual relations…. A more plausible suggestion is that monadic predicates are simply limiting cases of higher relatives. A nonrelative character, then, is a limiting case of a relative character” (p. 74).

The nonrelative is the limit case or “degenerate” case of the relative. Everything “is” a relation, in the sense that everything can be characterized in a relational way, without presupposing fixed terms. Pierce argues that the laws of physics do not presuppose fixed terms either; that reality is best expressed in terms of higher-order relations, which we can also more simply call higher-order things. Things are convenient hypostatizations of bundles of relations.

But the other essential side of this is that all meaningful differences discernible by common sense (at least all the good ones) are liftable into the higher-order context. A higher-order context means more difference and more distinctions. In no way does it connote an obliteration of difference or canceling of distinctions. It induces a kind of fluidity, as Hegel already observed. But in Pierce’s metaphor of debtor’s court, we still feel the reality of the sheriff’s hand on our shoulder.

“We can now return to the problem of relating monadic predicates to higher relatives. Pierce’s solution is reflected in three points he makes about collections. First, the older logic had reached its limit in treating things that are similar to one another as a collection; the logic of relatives provides the notion of a system that can be constituted by any combination of its members. Cause and effect, symptom and disease, the triadic relation of a sign to its object and interpreter, and, most important, a scientific law or mathematical formula — all constitute systems whose members are not necessarily similar to one another. The contribution of the logic of relatives, according to Pierce, is to treat a class or collection as a degenerate form of system” (p. 76).

A class or collection is a degenerate form of such a system, a sort of fossilized result.

“Generality, on [a common] account, revolves around the similarity of the members of a collection, which can be subjects or subjects or subject-sets” (pp. 76-77).

This similarity is none other than the resemblance of which the medieval logicians and theologians spoke.

“The lesson to be learned from the logic of relatives, Pierce insists, is that this scheme must be turned around…. The power of the new logic … is that it allows us to move not just from a sample to a collection, but from a fragment of a system to a whole system” (p. 77).

“We can approach the same idea from a slightly different angle by examining Pierce’s second point about collections: the distinction between discrete and continuous collections…. The most important kind of nondiscrete collection is that of possible objects” (ibid).

For me at least, this use of continuity is new and interesting.

Boler quotes Pierce, “The possible is necessarily general; and no amount of general specification can reduce a general class of possibilities to an individual case. It is only actuality, the force of existence, which bursts the fluidity of the general and produces a discrete unit” (p. 78).

As a “force of existence”, Pierce’s actuality is clearly not the actuality of that for the sake of which, to which I have given so much attention in Aristotle.

Boler continues, “Pierce eventually comes to hold that every predicate specifies a continuous collection of possible objects…. The quality spectrum that corresponds to monadic predicates is a simple form of the more complex continuity of a process. The events in a process are related not by being similar to one another, but by being ordered to, or successively realizing the end of, the process” (ibid).

Here we do have explicit mention of an end.

“There remains a third point about collections…. Pierce points out that a collection is not the same as its members. Even the collection whose sole member is Julius Caesar is not identical with Julius Caesar…. Pierce comes to define a collection as a fictitious entity made up of less fictitious entities” (pp. 78-79).

I think this has to do with the idea that nouns are “names” for collections.

“Pierce contends that the common noun is an accident of Indo-European grammar, being in reality only a part of the verb or predicate; the same is true of adjectives. But if ‘man’ is an unessential grammatical form, ‘humanity’ and ‘mankind’ are not. For the latter are not parts of the predicate at all: they are the predicate made into a subject by a process called ‘subjectification’ or, more often, ‘hypostatic abstraction’ ” (p. 79).

“Humanity” is more essential than “man”, because it more clearly refers to an essence, rather than to a concrete collection. “Subjectification” here does not refer to anything psychological. It is used in the quasi-Aristotelian sense that — in the same way as “hypostatization” — abstracts something as “standing under” something else.

“Some have held that abstraction is a mere grammatical change with no logical significance, but Pierce thinks this is a serious mistake” (ibid). “Pierce considers abstraction one of the most powerful tools of the human understanding. It is through abstraction that the mathematician is able to treat operations as themselves the subject of further operations. Equally important is the fact that the language of science abounds in abstractions: velocity, density, weight, and the like. Biological and chemical classification likewise require that the scientist deal with collections and their relations; and scientific laws and formulas are themselves the essential characters of collections” (p. 80).

Operations become the subject of further operations. And this is how we get to the idea of a subject as a thing standing under.

“Pierce’s insistence on the importance of subjectification is one reason why he rightly calls himself a Scotist…. Scotus considers abstraction proper to be the process whereby the mind operates on the Common Nature as known, giving it a numerical unity it did not of itself possess. Only the predicables, the second intentional notions like genus and species, are universals in the strict sense; but second order abstractions like humanity and whiteness are also universals (in a sense) because they are ‘fit to be predicated’: that is, they have a unity allowing them to be predicated of many individuals” (ibid).

The mind operates on the common nature, giving it a numerical unity it did not of itself possess. For Scotus this is an advancement of knowledge. But claiming for things a unity that they do not have is reductionism.

“For both Scotus and Pierce, abstractions can be treated in terms of either their logical behavior or their real reference. A biologist, for example, may use abstractions in speaking of a collection of animals or the differentiating character of sentient things, but he is not doing logic. Conversely, a logician may talk of the collection of fairies as an ’empty’ collection, but it is not a logical inquiry that establishes that there are no fairies; actually the logician is not interested in fairies but in collections…. In general, although any predicate can be made a subject by a logico-grammatical process, that process does not of itself determine that a collection or a character is real” (p. 81).

At a formal level this is clearly true. Subjects in this quasi-grammatical sense are abstractions from higher-order predicates.

“Consequently, it is important to distinguish in Pierce, as we did in Scotus, between second intention and abstraction. Second intention is ‘thought about thought as symbol’, and thus requires an act of abstraction: our thinking about things is itself made a thing to be thought about. Both logic and grammar make use of the process: ‘subject’, ‘predicate’, ‘noun’, ‘verb’, and the like are all second intentional terms” (pp. 81-82).

“As we reach the higher level relations of hypostasized relations, we sometimes lack names for the relations and use instead scientific formulas or laws. Even where we have the names at hand, the explicitly relational form of the law can be substituted. Such would seem to be the reasoning behind Pierce’s contention that what the scholastics called a nature was in fact a law of nature: the nature of a diamond, for example, consisting in a higher order character, a relation of relations, or law” (p. 83).

Here I think of the various passages in which Aristotle points out some commonly recognizable phenomenon that has no name.

“When Pierce says that some abstractions are real, he does not mean that they have the same mode of being as existing physical objects” (ibid).

Abstraction in itself is not subjective in the psychological sense. It designates a formal operation of giving a shorthand designation (a name) to something that previously had none. But then if we are not careful with our new shorthand, we may use it in an overgeneralized way that effectively is subjective in the psychological sense.

“The mental depends for its reality on someone’s thinking it, but then it has characters as a mental reality despite what anyone thinks about it” (p. 84).

I’m not fond of the term “mental”, but if we think of it merely as a named variable that gets its meaning from its use in various contexts, what he is saying is true. (What I call meaning (Fregean Sinn or “sense”) is not the same thing as reference (Fregean Bedeutung). Abstraction works on the technicalities of reference, which in turn depend on anaphora, or back-reference in speech to things that have not been explicitly named.)

“The fact that someone has made an abstraction is as real as the fact that someone dreamed. And just as this is not the issue when it is said that a dream is unreal, so it is also not the issue when it is said that an abstraction is real. The reality in question is the reference of the abstraction” (ibid).

If I give something a name, you may doubt its appropriateness (whether it is a good name), but regardless, it remains a fact that — for better or worse — I gave it that name.

“Real abstractions are distinguished first of all from second intentions, for the latter refer only to to entia rationis. A real abstraction, though itself an entia rationis, refers to something that does not depend on what someone thinks or thinks about it. Second, real abstractions are to be distinguished from abstractions which purport to refer to the real…. Notice that only experimental inquiry will establish the latter distinction…. The question of real collections and characters is something beyond this” (ibid).

Second intentions in this way of speaking are psychological or what I think of as spontaneous, in that they are formed at a material, preconscious level in the imagination, whereas abstractions are the result of formal or symbolic operations.

“As we saw, Pierce uses ‘relation’ to indicate a relationship said to be true of one of the objects related, usually the noun-subject, the others not being considered. In much the same way, ‘power’ seems to indicate a lawlike relationship which is said to be true of the noun-subject or, in this case, what is usually called the cause” (p. 90).

“What a power explains is the special regularity involved. When we say, for example, that a charged battery has a power which an uncharged battery does not, we imply that it is not a mere chance similarity that a motor attached to the battery will start. We feel that there is some reason why a motor attached to one battery will start while, attached to the other, it will not. As a matter of fact, we feel that there is something about the charged battery even when it is not attached to the motor which makes it different from the uncharged battery” (pp. 90-91).

Pierce here explicitly gives a positive sense to the scholastic way of explaining things by powers.

“[T]he nominalist has not yet explained why all pieces of opium cause people to go to sleep. Pierce may seem to say this, but I think his real reply is that the logic of relatives shows that to admit a real connection between taking opium and going to sleep is to admit a real general: a system whose members are the taking-opium event and the going-to-sleep event” (p. 91).

Boler says elsewhere that scholastic powers are used to explain the same kinds of regularity or non-arbitrariness that are explained by the higher-order relations that are expressed in scientific “laws”.

“The pragmatic maxim transforms ‘x is hard’ into ‘If x were scratched by carborundum, it would not leave a mark’; the hardness is the hypostatization of the relation between test and response” (ibid).

“The would-be, which Pierce insists upon in his later writings, is but the pragmatic equivalent of ‘power’ in the sense we have just discussed. In short, pragmatism is not just a matter of changing abstract terms into concrete ones; it is the very logic of abduction” (pp. 91-92).

“Abduction” is another of Pierce’s neologisms, formed by analogy with “induction” and “deduction”. It is what is involved in creative thought.

“At this point some remarks should be made about the noetic of abduction. From the above discussion, it seems obvious that there is some analogy between abductive inference and ‘seeing connections’. Indeed, Pierce calls abduction insight, instinct, and perhaps even intuition. But his own attacks on intuitive cognition suggest that something slightly more complicated is at work here” (p. 92).

The status of intuition is an area in which Pierce and Scotus are far apart. For Scotus, intuition is something objectively grounded in perspectiva, that gives us superior knowledge. Pierce on the other hand has Kantian scruples that make this kind of claim illegitimate.

“The fact that, out of an infinity of possibilities, the scientist can achieve his purposes with relatively few guesses suggests to Pierce that we have an instinct for the truth and that the mind and nature must be pretty much of whole cloth.”

Talking about these things is difficult, because the key terms are all said in many ways. Kant and Pierce reject claims of intellectual intuition as privileged access to immediate truth. Nonetheless Pierce says we have an instinct for the truth. The difference is that it is neither privileged nor immediate.

The non-separation of mind and nature and the “relatively few guesses” are consequences of the new realist understanding he is developing. The non-separation shows we are far from the dualism of Descartes. As Pierce himself recognizes, there is a degree of affinity between his work and that of Hegel. But this non-separation also represents a major difference from Scotus, who is motivated by an Augustinian concern to relate mind to a supernatural order and to separate it from nature. The very concept of “mind” as separable from nature in this way has an Augustinian heritage.

“[R]eality must be viewed as the goal of our mental activity and not its source” (ibid).

Similarly, knowledge and understanding are something we aim at, not what we start from. There is fertile ground for a Socratic ethic here. Knowledge is something we earnestly seek at every moment, not something we claim to already have. Aristotle’s unique orientation toward the primacy of the final cause was lost in his assimilation to the creationist paradigm through the introduction of an Avicennan abstract efficient cause as “cause of existence”, and only began to be recovered by Hegel. In making reality a goal and not a starting point, Pierce aligns himself explicitly with the broad outlines of Hegel, and implicitly with Aristotle’s unique insistence on the primacy of the final cause.

“Where William James praised pragmatism for its nominalism in reducing the meaning of a conception to particular experimental actions, Pierce says again and again that pragmatism involves realism” (p. 96).

The empiricist concept of “action” here attributed to James — a secular descendant of the Avicennan efficient cause adopted by the theologians to make a creationist Aristotle — is too narrow, too immediate, and too blunt an instrument to serve as a basic building block for the point of view Pierce is developing.

This affects the very nature of pragmatism. The Greek pragma (thing we are practically concerned with) and praxis (“action” or practice) come from the same root. The narrow concept of action as an impulse — which Galileo took from the first creationist commentator on Aristotle, John Philoponus (490-570 CE), who worked in the Alexandrian neoplatonic school of Ammonius — became attached on the side of nature to the Avicennan abstract efficient cause as cause of existence that had been promoted by the Latin theologians. In the resulting view, God as efficient cause works by creation, and nature as efficient cause works by a kind of impulse that led to the later billiard-ball model of mechanism.

With this division once achieved, it became possible for early modern writers concerned with nature to focus exclusively on the “natural” billiard-ball model. All action in the created world comes to be thought on the model of Philoponan impulse. One consequence of this is that action comes to be thought of as something immediate.

What Pierce objects to in James’ “particular experimental actions” can be understood as involving this kind of immediacy, which Pierce has already moved beyond, in what he himself recognizes as a convergence with Hegel. Hegel treats immediate action as an appearance, and against this develops his own much more ramified notion of practice, which he sometimes calls by its Greek name of praxis. Hegelian and Piercean practice replaces the narrow concept of immediate action with something understood in a deeply contextual way that is closer to what I have been calling Aristotelian “activity” or “act”.

Whereas James the charming and accessible behavioral psychologist thinks of reality as consisting in shallowly specifiable, immediate “actions” and “events” that directly cause one another, Pierce the obscure but brilliant semi-Hegelian logician thinks of it in terms of a vast and intricate evolving structure of if-then conditionals that condition one another, in ways that are analyzable in terms of his new theory of higher-order relations.

“The logical form of the conditional proposition is what Pierce calls a consequence…. The ‘conception of the effects’ referred to in the pragmatic maxim cannot be a statement of an event but must be a conditional statement. For Pierce, then, pragmatism shows that hardness consists not in actions or events, but in relations of actions and events” (p. 98).

“The stress upon the would-be, characteristic of his later writings on pragmatism, carries the relation of consequence one step further. If the hardness of a diamond consists in the conditional fact that it would give a certain response to a test, then hardness is not just this present and actual relation which holds between this test and this response, but a general relation that holds for all possible tests and responses of this type…. When I say that it would so react, there is no particular event I could now specify: in speaking of a possibility I am not speaking of a collection of discrete acts” (pp. 98-99).

Pierce’s “would-be” takes us into the realm of Aristotelian potentiality.

“Pierce concludes that the pragmatist must admit a theory of real possibility…. Pierce simply says that the conditional proposition of the pragmatic reformulation has a peculiar and essentially modal structure” (p. 100).

Real possibility is one dimension of Aristotelian potentiality. Pierce’s argument that everything is not reducible to events and actions parallels Aristotle’s critique of the Megarians (who reduced everything to a thinly factual actuality) in book Theta of the Metaphysics.

“Pragmatism shows that the meaning of a conception like hardness ultimately involves the notion of would-be, habit, or power. A power or habit is a nonrelational expression for a law” (pp. 101-102).

“One source of confusion lies in what I think is the mistaken notion that pragmatism must be a reductionist theory. A reductionist pragmatism, as I understand it, contends that only actual events are real — powers and laws, abstractions of all sorts, are only shorthand expressions for actual events…. That is to say, the pragmatic maxim is a formula by which all statements that are not event-statements are reduced to a series of statements containing only event-statements” (p. 106).

The latter-day reductionist repeats the error of the Megarians, who claimed that everything real is actual, while taking actuality in its non-Aristotelian sense of mere present factuality.

“It seems to me that Pierce’s pragmatism was never intended to be like this at all” (ibid).

“The gain is not that we have rid the world of powers and of laws, but that we have found a way of expressing our meanings so that we can tell a real law from a fiction” (pp. 106-107).

With this emphasis on expressing our meanings, we can see a Piercean background to Brandom’s “expressivist” view of logic.

“When I say that the way Pierce talks of laws and powers as explanations, I do not at all mean that I find what he says about causes and explanations to be pretty clear” (p. 108).

This talk of explanations suggests that Pierce ends up rediscovering something close to Aristotle’s own notion of cause as a “reason why”.

“[I]n denying that events are causes, Pierce is not denying that ‘individuals’, in the sense that Socrates is an individual, can be causes…. Pierce not only holds that Socrates is not an event, but he goes on to say that Socrates is not strictly an individual. For the realist, Pierce says, ‘things’ do not need reasons: they are reasons” (p. 109).

“[F]or Pierce it is the consequence and not the consequent which is at issue…. Pierce’s conclusion is that the pragmatist must therefore hold that some possibilities are real” (p. 111).

“He says, for example, that the idea that a law admits of no exception is nominalistic: there cannot be exceptions to a law that consists only in what happens” (p. 112).

“Pierce admits to the nominalist that a would-be can ‘only be learned through observation of what happens to be’, but he insists that a would-be cannot consist simply in what happens to be actual” (p. 113).

“Burks’s remark that ‘action is based on actualities, not on potentialities’ is only partly true for Pierce” (pp. 114-115).

“By insisting upon the conditional analysis of our conceptions, Pierce has incorporated into his system a special theory of real potentiality” (p. 116).

Pierce still has a less than fully Aristotelian notion of potentiality, limited to its “real possibility” aspect. But this is already a huge advance over the idea that immediate actions and events define reality.

“[C]ertain instances of predictive knowledge ‘oblige’ the pragmatist to ‘subscribe to a doctrine of Real Modality’ ” (p. 117).

Modal logic, which develops notions like possibility, necessity, and other kinds of constraint or conditioning, was very much out of favor in Pierce’s day, when monomorphic views of facts were overwhelmingly dominant. Since the later 20th century, modal logic been considerably developed, and Brandom has related it to more broadly philosophical concerns. Boler recognizes that Aristotle and the scholastics did work with modal logic.

“For Pierce, however, the predicate, if true, indicates a real relation to which the notion of form does not do justice. Form cannot ‘reach outside itself’. It is adequate for the static generality of similar things, but for the dynamic generality a principle of law or entelechy is needed” (p. 120).

Form in the sense of the species discussed in medieval perspectiva does have this static and self-enclosed character. Scotus introduced new ideas of formal distinction and “formal being”. In the present state of my understanding of Scotus, it seems that Scotus takes his bearings on the nature of form from the perspectiva tradition. But Albert the Great and Thomas Aquinas among others speak of form at least sometimes in a more expansive way, giving it some of the role that entelechy has in Aristotle.

For my own self, I find it hard to think of form as anything other than relational. The most elementary notion of form in Plato and Aristotle is probably that of geometrical figure. I have always seen geometrical figure in relational terms, rather than as a self-enclosed whole.

The Greek word in book V of Euclid’s Geometry for the ratio or relation of two magnitudes is none other than logos, which was translated to Latin as ratio. If we were to extract an implicit concept of form from Euclid’s use of figures, it would consist of many ratios or relations, rather than a single notion of shape as it appears in optics.

“We have already seen the prototype for this reasoning in Pierce’s theory of the illative copula. A consequence is more than an antecedent and a consequent, and a proposition is more than a subject and a predicate” (ibid).

Pierce’s “illative copula” is what is now called logical consequence, or a consequence relation. Each of the plethora of logics we have today can be conceptually characterized in terms of a differently detailed specification of the consequence relation.

“The relation of similarity is not adequate to handle the notion of process, even when similarity is treated in terms of a spectrum of possible variations. For the events in a process are related to one another not in being similar but by successively realizing a potency in time” (p. 127).

Here it sounds as though similarity is being viewed in the same way that sees geometrical figure as a unary “shape”, rather than a complex of relations. But in the recent series on Boulnois’s Being and Representation, it seemed that the usual scholastic way of talking about resemblance followed the perspectiva tradition’s decentered approach, seeing resemblance as a multifarious play of relations, rather than a putatively simple relation between two unanalyzed unitary shapes.

Next we come to the anti-psychologism in logic that Pierce seems to share with his contemporaries Husserl and Frege. (Pierce and Husserl are known to have actually corresponded.)

“Pierce is interested in dissociating ‘idea’ and ‘thought’ from the psychological connotation that someone has an idea or that a thought is in someone’s mind. The thought-like character of a real law does not result from someone’s thinking it, but from the element of final causation that is involved in its operation” (p. 130).

Here we get to a few more connections with Aristotle. Even if Pierce’s recovery of the notion of final cause is stunted by his overemphasis on temporal development toward a future, it seems that he does follow Aristotle and Hegel in recognizing that first things come last in the order of knowledge.

[Pierce:] “The thought thinking and the immediate thought object are the very same thing regarded from different points of view” (quoted, p. 131).

Like Hegel, Pierce endorses Aristotle’s thesis of the inseparability of the thought that thinks from what it thinks.

“For Pierce, however, the predominance of continuity tends to eliminate the concept of substance, and the supposit (Socrates, for example) comes to be treated as a process. What we call ‘things’ are not strictly individuals but generals. Socrates is not just a member of a collection, partaking in generality through his similarity to other men; he is a fragment of a system. A dynamic process himself, the human person is continuous with that system which is humanity and which is, in turn, continuous with the whole evolution of Reason” (p. 141).

Substance in the later tradition came to be highly reified. The more fluid view of substance that Pierce emphasizes is another thing he shares with Hegel, and indeed with Aristotle. Pierce is reportedly a major influence on Whitehead, both on logic and on Whitehead’s central notion of process.

“What emerges from the discussion is a world of process, characterized by continuity and set in motion by the rule of Reason through final (and not efficient) causality” (p. 144).

“Continuity” seems to be Pierce’s preferred term for the more fluid view of substance. This is the climax of Boler’s book. To me it sounds more Aristotelian than Scotist, because Scotus is one of the great historic promoters of Avicennan efficient causality. What follows, while it makes a number of additional points about Pierce’s relational perspective, is mainly a summary.

“The objective generality of a predicate is a matter of its reference to many subjects. This becomes critical when the predicate is itself made a subject of further operations. This process, which Pierce calls hypostatic abstraction, can be accomplished in terms of either extension or comprehension. In an extensional treatment we utilize the notion of a collection: something constituted of members all of which have some character, however trifling. In the comprehensional analysis the character itself becomes the subject of discourse. Here Pierce’s relational treatment of predicates comes to the fore.”

Pierce’s “hypostatic” abstraction is a new and valuable characterization of what abstraction actually is. I suspect it is in some way ancestral to the computable notion of abstraction developed by Church in the 1930s, where abstraction consists in giving some unnamed thing a name.

“A collection is made up of similar members. But the logic of relatives allows the development of the more interesting notion of a system. In a system the members are not necessarily similar to one another; the mode of connection is something more complex, such as giver-of-to, cause-of, quotient of, and so forth. Any relational character delimits a system whose members are the subjects of the proposition having that predicate. Thus a relative predicate can be general in three ways: (1) as itself a sign; (2) as delimiting a system (or set); and (3) as true of many (sets of) subjects.”

There is a one-to-one mapping between predicates in the sense of predicate logics, and what are here called relational characters.

“Induction is suited only to collections; it infers that the character of a whole class is the same as that of the sample upon which it operates. The character that each member has may be quite complex, of course, but it must be the same in each member. The move from fragment to system — which is pretty much what is ordinarily called seeing connections — is a different mode of inference, namely, abduction. The operation of hypostatic abstraction involves abductive inference. To make a predicate a subject is, in the logic of relatives, to treat a relation as a thing; thus it requires, if only trivially, that the relation be recognized as significant to begin with. Pierce points out that the resultant ‘thing’ is a creation of the mind, an ens rationis” (p. 146).

We treat a relation as a thing by giving it a name that allows us to refer to it. Naming an unnamed thing is a creative act of the same general sort as seeing a connection.

“An abstraction, like a dream, is a fact in someone’s mental biography. When the realist contends that some generals are real, however, he is concerned with the reality of that to which such an abstraction refers. Abstractions of second intention refer only to the mind’s way of representing objects, and not to the things represented. Real abstractions are also ‘second order’ conceptions, but the objects to which they refer (namely, the thirdness of things) are, or purport to be, real aspects of things, which can be called ‘realities’ ” (p. 147).

I won’t attempt to explain “thirdness” here, but we have already seen a few hints. It is related to composition and consequence.

“The nominalist contention, according to Pierce, is that wherever generality is found, it is a function of the symbol as symbol — that is, of a second intention — and does not reflect a generality independent of the mind. Pierce hails as the nominalist’s true contribution the correlation of a general with the activity of a symbol; that is, Pierce argues that the general is of the nature of a word or an idea. But for Pierce the important question of whether a general is real still remains unanswered. At this point the issue begins to exceed the limits of logic, for it becomes necessary to distinguish within first intentional abstractions those that are objective and those that are subjective. On Pierce’s account, such a distinction cannot be made by the logician, for it turns upon the matter of successful prediction” (ibid).

“The special contribution of Pierce’s pragmatism now becomes relevant. The pragmatic formulation makes the rational purport of any conception consist in the truth of a conditional proposition relating to the future. This means that (1) every predicate involves (virtually) a relative character, which brings into prominence the generality of the character itself as a system, in contrast to the more commonly recognized generality of the collection of similar (sets of) subjects; and (2) every predicate becomes a virtual prediction. Of course, pragmatism does not verify predictions; it simply puts our conceptions into a form that will allow for the scientific inquiry which alone can separate law from fiction. The fact of scientific prediction, however, shows that in some cases something more than an accidental succession of events or a simple uniformity is involved. Ultimately, prediction shows there is something real now that accounts for a future actuality; and since the only actuality involved is the future event, the present reality must be a possibility” (ibid).

Pierce’s consistent emphasis on the relations he invented under the name of “relatives” could be an early alternative to the set-theoretic foundations of mathematics that were being developed around the same time, though I don’t know that Pierce ever presented it as such.

“It should be clear by now that Pierce’s pragmatism involves not only the belief that generals are real, but a special conception of the nature of real generals. This brings us to the last phase of Pierce’s realism, where he criticizes the attempt to account for real generality by form alone. The schoolmen, as Pierce sees them, realized the importance of habits or dispositions, but unfortunately they treated them as forms. Lacking the logic of relatives and pragmatism, they were unable to do justice to the relational structure of real generals. The result was a static doctrine of substantial forms that could not account for the important elements of continuity and process” (p. 148).

Neither the scholastics nor Pierce understood form in a relational way.

“Scholastic realism was a step beyond nominalism, for it could account for the generality of qualitative possibility, the generality of monadic predicates. But the notion of potentiality, of would-be instead of might-be, could only be grasped in the dynamic conception of law. That is, the unity of a process is found not in the similarity of the events in the process, but in the more complex conception of a system that orders those events. The distinction here is that of firstness and thirdness…. Also involved is the idea that a relative is a system that not only delimits a collection of similar (sets of) subjects, but relates the subjects of each set. This activity of relating Pierce calls ‘mediation’, and he considers it definitive of thirdness” (ibid).

According to Boler, Pierce uses the Hegelian term “mediation”, and “considers it definitive of thirdness”. In Pierce’s day, the old overemphasis on the thesis-antithesis-synthesis triad in elementary accounts of Hegel was very much dominant. This may have influenced Pierce’s odd choice of “thirdness” for one of his key concepts. The connection with Hegelian mediation is far more illuminating.

“[T]he argument that a would-be is not the same as any collection of actualities, is again applied in the broader field of the reality of some thirdness. Pierce has so described secondness that nothing is included in it except the bare reaction-event; as a result, he has no difficulty in showing that thirdness is not contained in secondness” (p. 149).

As throughout Boler’s book, actuality is used only in the thin sense of a present state of affairs. But the important and valuable point is how the would-be decisively moves beyond this.

“If the individual as such is a bare event, it is difficult to avoid Pierce’s conclusion that there must be some real generality in the objective make-up of the world. As to the ordinary notion of a person or ‘thing’ as an individual, Pierce more or less denies it. The person or thing is a ‘cluster’ of potentialities, and therefore a habit or law itself. The important problem of Socrates’ relation to humanity is now not so much a question of the relation of an individual to a type, but of a fragment to a system” (ibid).

We even get a partial recovery of Aristotelian potentiality.

“Because of the emphasis I have placed on it, the nature of the Scotistic element in Pierce’s realism deserves a separate, if brief, summary. The distinction of two problems of realism is Scotistic, or at least scholastic. And within the logical analysis, Pierce’s treatment of abstractions as ‘second order’ conceptions is definitely Scotistic. From this issue the discussion of ‘real’ abstractions arises, and Pierce himself has acknowledged his indebtedness to Scotus for the use of the term ‘real’ ” (pp. 149-150).

This suggests that there is in Scotus somewhere a relatively explicit discussion of what would now be called second-order things. Unfortunately, though the book includes many citations to the works of Scotus, there is none for this one.

“Once the question of logical predicability is handled, Scotus turns his attention to the Common Nature. It is not a supposit, for the evidence indicates that it consists in a less-than-numerical identity. While it is real, the Common Nature is not a separate substance; indeed, the mode of its unity suggests a different mode of being. The Common Nature is to be found, in a certain sense, in individual things, but it cannot be identical with the individuality of such things. Ultimately, Scotus decides that the Common Nature is not a res [thing] but a realitas [reality]: something essentially conceivable but real before the operation of the intellect. These realities — or formalities, since they are ‘formally distinct’ from one another — are neither physical things nor logical concepts. They are real, but in what has been called a ‘metaphysical mode’ ” (p. 150).

“Scotus’ arguments for the real lesser unity are supplemented in Pierce by the arguments from the fact of prediction. Pragmatism and the logic of relatives influence the conception of the structure of these realities: what Scotus held to be formlike nature Pierce conceives of as a law of nature. But Pierce’s laws have a different mode of being from individuals and they retain a strong resemblance to Scotus’ metaphysical mode — in fact, Pierce also calls them realities” (ibid).

“There are differences in the two theories, of course…. The main difference lies with Pierce’s self-acknowledged denial that the nature is contracted in individuals…. The important point, however, is that in the very fact that Pierce denies the Scotistic doctrine of contraction he reveals the extent of Scotus’ influence: the framework of Scotus’ solution to the problem of universals, without the notion of contraction, provides the basic points of reference for the structure of Pierce’s own theory” (ibid).

I think there are quite a few more differences, but at least from this account, it seems as though the realist arguments of Scotus are largely if not wholly independent of his voluntarism.

Contingency

While researching Duns Scotus for the recent series, I ran across an article claiming that Scotus provides an underpinning for what it called the modern view of contingency. Once again, Aristotle’s concern for things said in many ways is extremely relevant for making sense of this.

Ordinarily, contingency is only involved when one thing depends on another. When one thing depends on another, we say that it is conditional. That which is conditional is not in itself necessary. It is also called possible. But possibility itself is ambiguous. Many things that are logically possible are not practically or “really” possible.

Logical possibility includes anything that is not self-contradictory or “incompossible”, as Leibniz would say. This kind of possibility is a fundamental concept of modal logic, where analysis in terms of possible worlds has become dominant since the 1960s, due to the influence of the analytic philosopher Saul Kripke. The term “possible worlds” is inspired by Leibniz, who argued that creation should be rigorously understood as applying only to a whole “compossible” world.

The requirement of compossibility or realizable combination treats every possible world as a rational whole, in which things have real dependencies on other things. Even God will never actually do things that are not “possible together”.

This is not compatible with extremist claims that eternal or even logically necessary truths could be arbitrarily revoked at any time, or that there simply are no eternal or necessary truths.

It is easy to draw illegitimate, sophistical conclusions about what seem to be eternal or necessary truths. That does not mean that there are none, only that the way to clarity in these matters is difficult. But advocates of what are really extremist views take advantage of this, to draw illegitimate, sophistical conclusions of their own. What makes this easy is that it “only” requires ignoring aspects of the relevant context.

The classic early modern “metaphysical” view treats individual things in a kind of artificial isolation that never occurs in the real world. Needless to say, this kind of anticontextual metaphysics has nothing to do with Aristotle. Such a view has been attributed to Leibniz, based on a shallow interpretation of the Leibnizian monads. This fails to take into account either his general emphasis on whole worlds, or his explicit claim that the internal detail of each monad reprises the entire universe from a certain point of view. But it does seem that something like this was characteristic of the Wolffian school, which was the main concrete target of Kant’s criticism.

The contingency that that article on Scotus was celebrating was a form of radical “contingency” like that advocated by al-Ghazali, Ockham, and Sartre, among others. This occasionalism is the extremist view that nothing in or about the world is intrinsically firm or solid or substantial.

The essential point to understand about this is that radical contingency abolishes ordinary contingency.

Ordinary contingency is relational. We say that A is contingent on B. One thing (or action or status) either constrains another thing, or removes a constraint on another (in the sense that we speak of removing contingencies on a loan). Contingency in the ordinary sense by definition implies 1) some relevant context, and 2) some relevant constraint(s) that may or may not apply in that context.

One thing could never remove a constraint on another if there were really no such thing as constraint in the world. Similarly, a too-open view of possibility — one that posits an absolute freedom or absolute power — eliminates all meaningful modal analysis of possibility, because it eliminates any contrasting element of impossibility. To make no distinction — for example to claim that absolutely anything is possible — is effectively to say nothing. Claims of radical contingency eliminate the basis for ever saying “A is contingent on B“.

A defender of radical contingency might claim that there is something all A are contingent on — a will. But this is circular, because claims about the existence of a will over and above meaningful choice between alternatives are only introduced in order to putatively justify claims of radical contingency.

Kindly Objectivity

I am accustomed to thinking of objectivity in ethical terms, as a kind of fairness and magnanimity. Thus it was a little shocking to learn that the original meaning of “to regard objectively” was “to regard as an object“. Etymologically it fits of course, but I am also used to the idea that we should not treat people as objects. I have pushed this further, and said in effect that we should not even treat inanimate objects as mere objects.

But it seems that the positive moral connotations of objectivity may in fact have arisen from a valorization of seeing things as objects, even though objective being was called a diminished being. Henry of Ghent, for example, apparently held that a pure intelligence would see everything purely as an object.

The pure object is something that is implicitly mastered in every respect. That is why we should not treat people as objects, and why we should not even treat objects purely as objects.

Sunrise of the Object

Olivier Boulnois’s deep “archaeological” investigation of the evolution of the concept of representation in Duns Scotus and his near-contemporaries has important implications for interpretation of the origins of distinctively modern thought.

Heidegger, Foucault, and Brandom have all seen Descartes as the main instigator of a paradigm shift that reoriented Western thought around the concept of representation and the subject-object distinction. But on the side of the subject, a very thorough case has been made by Alain de Libera and others that the distinctive characteristics of the broadly modern notion of a “subject” of consciousness had already emerged in the late 13th century.

Boulnois’s L’Être et représentation [Being and Representation: A genealogy of modern metaphysics in the era of Duns Scotus (1999)] makes a similarly thorough case for a late 13th century origin of the modern notions of object and representation. I will never again be able to innocently use the word “objectivity” for a kind of moral quality concerned with fairness in judgment — as I have been prone to do — without feeling a need to worry about these other connotations.

For now at least, this post will conclude my translations from Boulnois’s important book. It will take us to the end of his second chapter. The other four-fifths of the book move on to other topics, including Scotus’s concept of “concept” and its relation to Augustine’s trinitarian-theological model of human memory, intellect, and will; Scotus’s famous theory of the univocity of being; Scotist arguments for the existence of God; the role of Suárez in conveying broadly Scotist ideas into early modernity; and finally, how some of this shows up in Kant.

In future I may come back and address two interesting and somewhat unexpected views of Scotus that Boulnois brings to light later in the book. One is that the soul of the wayfarer never has full, immediate self-knowledge. The other is a notion of pre-existing divine ideas that seems as though it might put some limit on Scotus’s otherwise extreme voluntarism. (Although Boulnois has elsewhere astutely criticized voluntarism; purported voluntarist readings of Aristotle; and strong versions of omnipotence such as the one Scotus advocates, in this book he limits himself to sympathetic exposition.)

He begins this section by recalling the way that Aristotle’s only recently translated account of human knowledge of sensible things was understood by his Latin readers in the 13th century.

“For the noetics of the last third of the 13th century, the question of the mode of being of the object of knowledge is posed along the lines of [Aristotle’s] On the Soul. When I perceive a thing in itself, a doubling is produced. It is necessary to distinguish two aspects: the thing outside of me (object of perception), and the knowledge I have of it by an act of the soul (place of perception). The soul is the support, or the subsistent subject of the knowledge of the object. Thus the real being in nature is not the same thing as the being in the soul (ens in anima). The latter is first of all a ‘quality of the soul’, that is to say an accident that happens to my thought, and that only has subsistence through my thought. But this accidental being is secondary and imperfect in relation to the substance perceived, while the substance itself is perfect and primary. In contrast with this accomplished being, the mode of being of knowledge is that of being incomplete, lessened, diminished, ens diminutum” (pp. 88-89, my translation throughout, emphasis and ellipses in original throughout).

This is not so much Aristotle’s own view as a thoroughly Latinized account, which for instance already assumes the new Latin terminology and viewpoints of “subject” and “object” that have no place in Aristotle.

“As a consequence, the being of thought is doubled. A prefiguration of objective being, it can be considered under a double point of view, as object of thought or as form of thought. In the first case, it is a matter of what we think, of a vis-a-vis for the inspection of thought. In the second case, it is a matter of that by which we think, insofar as thought is in the thinker, according to its diminished being. Roger Bacon underlines this duality: ‘The being in the consideration and the conception of intellect can be in two ways: either as a species and a habit of thought existing in the intellect, or as accidents in a subject, that is to say like a thing in the measure that it is conceived and considered in act.’ Knowledge is a ‘way of conceiving’, a bifid aspect of our intellectual activity: it simultaneously recalls a being in the intellect and a being of the exterior object. The reality considered is only attained by means of a concept or a mental form” (p. 89).

There is a partial precedent in Aristotle for this doubling that becomes so prominent in the Latin context. Aristotle’s concern for how this or that is properly said simultaneously addresses both norms of linguistic practice and how things really are. Aristotle seems to delight in using expressions that can reasonably be read in either of these two ways. I think this is a deliberate strategy on his part.

But as Boulnois makes clear, the role and meaning of the doubling in the 13th-century context are quite different. Whereas Aristotle wants to show us that there is a deep relation between the ways we express things in language and the ways in which we understand reality, his Latin readers draw lessons about the need to distinguish between the thing in the soul and the thing in the world. The Latins partially anticipate what in Kant becomes the notorious problem of the “thing in itself”.

“This ambivalence is not anodyne. For sure, it designates knowledge either as a part of the soul, or as recalling the thing outside of me. But precisely, this ambiguity does not recover that of the thought in me and the thing outside of me. The notion of object comes to be interposed in this serene correspondence: what thought attains is no longer the thing in itself (that it aims at, and to which it refers), but the thing thought (that it signifies under a determinate form). [quote from Bacon:] ‘Certain habitus are in the soul, under the reason of the habitus, and thus they are in themselves in the soul or in the human. There are others that are under the reason of the object, because they are made object (obiiciuntur) to the intelligence, and truth and falsity are of this kind.’ Truth has come under the regime of the object. It is no longer the sensible reception of the thing itself, but the correspondence between the object pursued by the activity of the intellect, delineated by a form immanent to that activity, and its form conserved in the soul by a doublet in reduction. The being of the thing thought can no longer return to the being of the thing in itself. The plane of objectivity is detached from the surface of the world” (pp. 89-90).

Here we have also an explicit articulation of a correspondence theory of truth. This is not simply because Boulnois uses the word “correspondence” in his account, which may be an interpolation. Rather it is because of what is being said about the relation of truth to what among the Latins is now explicitly called an “object”.

“The object is the reason under which a thing appears similar to its form in the soul. What is produced by thought in the intellect has a double mode of being: as form received or disposition acquired (habitus), it is a reality in the soul, but it is also an object for thought; it thus has the mode of being of an object. Truth is identified with objectity in its double aspect — falsity is a defective relation between these two aspects, a division between thought and the object. Truth has passed under the regime of the object, but the being of the object has no clearly assigned reality. What is the term of an aim of the soul, if it is not confirmed by a relation exterior to the soul, identical to the thing itself, or confounded with the concept the intellect takes of it?” (p. 90).

The answer to this rhetorical question is the object. The Heideggerian term “objectity” here is definitely an interpolation, but the variants of the Latin term “object” that appear for the first time in the 13th century clearly are attested in texts from that time. The notion of intentionality derived from Avicenna seems to call for a notion of something in the syntactic place of the object of an intention, regardless of what we call it. I keep thinking too of Husserl’s intentional objects, as a kind of model for how to think the nonempirical, non-naturalistic status of objects in Scotus.

The term “object” refers originally to the object of an Avicennan intention, not to a thing in the world. But Boulnois elsewhere lists a number of different kinds of things that Scotus refers to as objects, including objects of perception. Yet it seems that there is also supposed to be a univocal meaning of “object” that is applicable in all these cases. The way this is all supposed to fit together may have something to do with Scotus’s thesis of the pre-existence of universals in memory, before any intellection in act. This also reminded me of Husserl’s “passive synthesis”.

“In this perspective, what poses a problem is less the doubling than the continuity between the two senses of object. How is it the same reality that we consider from different points of view, sometimes as an immanent part of the soul, sometimes as a transcendent intentional content? What guarantees to us that it is indeed the same being that we consider as a diminished accident in the soul or as an object for it? Can we think the intelligible species otherwise than as a species received in sensation and transmitted to the intellect? To respond to these questions, many theories confront and compete with one another” (ibid).

“– At the beginning of the 13th century, the theory of spiritual being came down to saying that sensible species carried by light transport information under the form of a material spiritus. The species are received in the one sensing and transformed into a spiritual, thought reality. Thus the transmission of form in a medium is spiritual, like that of light in the diaphanous medium. And the form known is no longer the material form, like the concrete form of a colored body, but the pure, intentional form, that of color, detached from all corporeity. It will be necessary to redouble the mode of being of perception, to distinguish between the material transmission of information, and that which is recognized by the pure intentionality of the faculties. In one same perception, the soul perceives at once a (material) reality and its (intentional) signification” (p. 91).

“– The theory of esse intentionale [intentional being] prolongs that of esse spirituale [spiritual being], but consists in saying that the sense undergoes the effect of this or that quality, and in conformity to its logos. The sense receives not the concrete singularity of the thing, but the sensible quality that defines its intentio, its rationally defined essence. The intention designates at once the form of the thing, the immediate emanation of a species, and the image of the form of which it is the species. The theory of intentio translates at once causality and resemblance: the intention is caused in the medium and in the sense by resemblance to the model that is its cause. It nonetheless does not permit thinking a knowledge that is detached from physical causality and does not depend on the causality of the mind” (pp. 91-92).

“– At the end of the 13th century, the theory of esse obiective [objective being] seeks to remedy this difficulty. The apparatus of representation reverses natural causality in being objective. It allows to be considered no longer the sense of the physical production of an image, but the sense of intentional reference by which the image refers to its original. All the art of painting rests on such a theory. [quote from Giles of Rome:] ‘A canvas is called image as a painting, not in that the canvas is itself an image, but because a painting is on it that is an image.’ It is neither the support nor the surface that makes the representation. They are only its material subject. But the representation comes from the traits of resemblance introduced by art on the support. [quote from Giles of Rome:] ‘And in the same way, knowledge is called a word, not because it is itself a word, but because it has a being in the word.’ It is not the real status of the concept taken in itself that makes it a representation, but its character of resemblance founded on a real term relating it to the object. Knowledge is not in the term that represents but in the relation, in the intentional system that permits the representation in the soul to refer to its object in the world. The system of representation is the path of similitude, beyond its physical support” (p. 92).

In this way, knowledge becomes completely separable from naturalistic determination.

According to Boulnois, the new 13th-century theory of “objective being” does not originate with Scotus, but he is the one who develops it to the fullest.

“For Henry of Ghent, objective being designates the being known of every thing in the intellect. He precisely develops this theory in connection with angelic knowledge: the angel undergoes no sensible impression. As consequence, what is present to angelic thought is not imprinted in it, but present as the term of an aim — objectively. Thus being as being, insofar as it is conceived, is aimed at objectively, and is the first of all concepts. Being and truth have passed under the yoke of objectivity, because they are known under a concept” (pp. 92-93).

According to this way of thinking, to be objective or to be an object is precisely to be the term aimed at by an Avicennan intention. More generally, it is always possible to take the term of an aim in a purely relative way, as whatever the aim aims at, without prejudice to whatever characteristics it might have independently.

(This is not the place for a long digression, but I think Hegel and Brandom each develop an alternative concept of “concept” that does not put being and truth under a “yoke of objectivity”.)

“It is the act of representing that allows the passage from being to objective being: the constitution of the object is not passive, but active. Scotus continues on this path. He removes the domain of the objects of thought from their empirical origin and from natural causality, to give them an intelligible dimension. He thus radically separates the domain of worldly reality and that of objectivity; that of natural causality and that of intentional aim; that of efficiency and that of formality. The object is not the species that moves the intellect, but the term it aims at. [quote from Scotus:] ‘The object is by itself the mover of the intellect’, according to which the intellect is assimilated to the object, [quote from Scotus:] ‘indeed the object is the mover of the intellect according to the formal and absolute being of the object, and not according to the being it has in the phantasm, insofar as the latter designates (denotet) something different than the formal being of the object; but the formal being of the object agrees perfectly with the object in the thing itself; thus the object, insofar as it is in the thing itself, is a sufficient mover for the intellect’ ” (p. 93).

The objectivity of the object in this view is not simply the reality of the thing, as we might infer from common speech. All the troublesome and polysemic aspects of the reality of the thing are here conveniently excised.

“The force of the Scotist position is to distinguish two orders in representation, two sorts of intentionality: — the representation of the particular sensible thing in a particular sensible species (esse intentionale); — and the intentional aim of the object in its objectity, that is to say as the term aimed at in conformity with the mental word, which is ‘that in which the intellect is assimilated to the object’ (esse obiective). At that moment, the object is aimed at intellectually according to a certain ratio [reason] that is really in the thing. There is an active solicitation by the intellect, which pursues an intelligibility in the thing. And reciprocally in the measure to which this intelligibility is really in the thing, we can say that this thing, under the angle of this objectivity (or intelligibility) is the secondary moving cause of the intellect that thinks” (ibid).

The second sort of intentionality here partially anticipates Husserl’s usage, in which intentionality no longer refers to anything empirical. Husserl’s great diligence in avoiding unsupportable spiritualist claims about his postulated nonempirical intentionality shows that such a combination is at least possible.

At the same time, intellect is here given an active role not only with respect to intelligible content, but also in sense perception in ordinary life. This is worth dwelling upon at length, because highly respected and respect-worthy writers have lent their support to a summary judgment that human intellect was universally viewed as passive in pre-modern times.

Finally, the real thing is at the same time allowed a causal role in sense perception. It is not wrong to call that an Aristotelian position, though of course that is not the end of the story for Aristotle. Meanwhile, elsewhere in the book, Boulnois cites several texts from Augustine that Scotus uses in order to argue that Augustine himself explicitly treats the thing perceived as playing a secondary co-determining role, alongside the active role of the human intellect. I did not recall this.

The combination of all three of these elements is impressive.

“The formal being of the object is an a priori that competes with the phantasm in the formation of the intelligible species. [quote from Scotus:] ‘The formal mover of the intellect is the object itself in itself, according to its causes and its properties, but not the phantasmatic being, which signifies the representative species insofar as it is other than the formal being represented.’ The intellect aims actively at the formal object, and attains it directly as the intelligible nature (or is moved by it), thus constituting the mental word by itself, even if it does so in the present state with the concomitance of the phantasm. The formality of the object is constituted a priori in thought, and not received from experience” (pp. 93-94).

Earlier, Boulnois positioned the a priori in Scotus as contrasted with both innate ideas and divine illumination. That there is another alternative is an appealing prospect, but I am doubtful about any a priori constitution of objects, and about whether Kant would accept this way of speaking. There are several subtle syntactic distinctions related to this question. In Kant there are a priori concepts and arguments and judgments, and Kant seems to have regarded the completely general concept of “object” as a priori. Toward the end of the book, Boulnois suggests a Scotus-Suárez-Wolff-Baumgarten genealogy for Kant’s notion of an object in general. But if we speak without qualification of an a priori constitution of objects, this seems to refer to objects in general, and thus to include particular objects. But while the completely abstract notion of object might be a priori, it is hard to see how any particular object could be constituted a priori.

What Boulnois is calling the formality of the object here is what Scotus calls formal being. This was a new concept in Henry of Ghent and Scotus.

Numerous sources seem to treat formal being in Scotus as immediately following from his notion of formal distinction, but I have serious doubts about that transition. That there is such a thing as formal distinction — according to which things can be really inseparable but definitionally distinct — seems very reasonable, but there is a serious question also of how this is to be applied. For example, Scotus apparently holds that the distinction of essence and existence is purely formal, but that of soul and body is real (he rejects Aristotelian hylomorphism). But someone might defend Aristotelian hylomorphism, or doubt the claim that essence and existence can be reduced to the same plane.

“Everything thus rests on the ambiguity of the very status of representation: the latter is at once the act of conceiving and perceiving the object (the act of representing), and the resemblance of the thing perceived (the representative thing). Representation as substitutive object, or the resemblance of the thing, is the result of a real perceptive trajectory. It is imprinted solely by the body that is represented, which is the partial cause of it, while the act of representing is an operation of the soul, sustained by the exterior presence of the object. Species permit logical predication. They are also Porphyrean objects (universal classes). But if they are sensible qualities, how can they at the same time be the immaterial representations of objects? It will be necessary to distinguish two senses of representation: the passive reception of a sensible object in the possible intellect, and the active elaboration of thought expressing the definition of the object in the agent intellect” (pp. 94-95).

“The universal only has real being in the measure that it is present in a form, so that the agent intellect produces another real term from the species representing the singular. The universal is represented in the mental image, because it is the original aimed at in a univocal and expressive manner, as Hercules is represented in his statue. The term of the activity of the agent intellect is indeed something real, a form given existence, that formally represents the universal as universal. This representation has for its intentional correlate a ‘represented being’, the objective being to which it refers. This represented being is only a diminished being, since it is not really present in the representation, but it is the obvious referent of it. When knowledge is no longer the reception of a form similar to that of the thing perceived, but the engendering by the intellect of an interior word or of a concept, knowledge is made by representation. The mode of being of the knower becomes a representation, the mode of being of the known, the objective being of the represented” (p. 95).

It may be that some of the scholastics identified knowledge in general with the simple reception of a form, but that is not true for Aristotle. In Aristotle I don’t think it is true even for knowledge of sensible things, though it might be true of simple perception.

The notion of a mental image is problematic in this context. “Mental” is not an Aristotelian term, but has an Augustinian provenance, and there is no image in Aristotelian intellect. In an Aristotelian context, I would expect anything that is called an image to be associated not with intellect, but rather with imagination. But Boulnois seems to be implying that it is nonetheless appropriate to call the medieval intelligible species an image. Sensible species seem to have a Stoic origin, but both sides of the debate for and against intelligible species only arise in the scholastic tradition.

The term “mental” here reflects the Augustinian mens or “mind”. This has sometimes been equated with Aristotelian “intellect”, but the two are described in very different terms. Augustinian mind is much more like what the scholastics called intellectual soul (for which Augustinian mens — along with some original ideas of Avicenna — was the main inspiration). Even if we were associating “mental” with Aristotelian intellect, it would not be right to associate an image with it (since images belong to imagination, broadly construed).

“The act of giving the mental image the status of a representation is already sketched by Thomas Aquinas and systematized by Henry of Ghent. But the great originality of Duns Scotus consists in making this representation a reproduction: not the image acquired or received by the sense, such that the imaginary repraesentatio becomes intelligible, but a real production by the intellect, distinct and separate from the reception of the sensible phantasm. Duns Scotus can adopt the adage according to which ‘the act of knowing is a participation in the object by a resemblance to it’. The intelligible species guarantees that knowledge is not a simple transversal similitude, but an intellectual image in causal, essential dependence on the form of the object. It is ‘not only a resemblance, but the imitation and reception of the form of the model (exemplatio passiva). But he adds immediately, ‘I don’t mean to say resemblance by communication of the same form, but resemblance by imitation, as the copy (ideatum) of the idea’. Image, participation, resemblance yes, but never the donation of a form, and always by copy and reproduction. Knowledge is not the direct communication of a form, but the imitative representation, the production, in a different mode of being, of a copy in the image of the thing itself, its original. The mental image is not in the prolongation of a being-received. It is constituted in and by the intellect. Representation is an imitation of the object: the eidos (whether we translate this word by idea, species, or form) is not attained in itself, but in its objective conformity to the representation, starting from its imperfect givenness in the image of the object, that is to say in its ‘objective being’ ” (pp. 95-96).

Later, Boulnois will say that knowledge for Scotus is to be identified not with a representation, but rather with a relation involving the representation. That seems more sound. Here and above he is speaking about the “knowledge” involved in the experience of perception.

The technical concept of real production is another scholastic innovation, tied to the new non-Aristotelian notion of efficient causality. The idea of a constitution “in and by the intellect” is at most implicit in Aristotle; it fits more easily into an Augustinian or Avicennan context. It is arguably consistent but not obvious that such constitution is a real production.

The “mental image” or intelligible species in Scotus is sharply distinguished from the sensible species. Aristotle neither affirms nor denies such a thing. I believe the reason Aristotle is so minimalist on topics of this sort is that he wants to avoid speculation, and does not think we have the means to know whether propositions of this sort are true or not. That would be consistent with his rejection of immediate self-knowledge.

Although generally more Augustinian than Aristotelian, Scotus according to Boulnois sides with Aristotle in rejecting immediate self-knowledge.

(Boulnois also says that the Latin notion of intellectual intuition is principally grounded in the tradition of perspectiva, which he also says assumes in its geometrical-optical theory that there is an irreducible multiplicity of points of view, no one of which covers the entire field. It was only in the Renaissance that realism in painting came to be associated with the portrayal of everything from one single point of view. And the decentered multiplicity of points of view typical of medieval painting was apparently echoed in the multiplicity of perspectives in medieval geometrical optics. Though I’m still doubtful about any intellectual intuition, these qualifications are both interesting and important.)

“The agent intellect operates less by abstraction than by transferring the object from the order of the sensible to the order of the intelligible. From the singular sensible impression, it makes an intelligible universal. Duns Scotus likes to deduce this transformation from the texts of Aristotle, but it is clear that he has abandoned the Aristotelian horizon, for which the transformation of thing into known object follows the schema of power-act, or matter-form” (p. 96).

When he says “transferring the object”, it sounds like it is the same object, but it cannot be, because he emphasizes that it is a new production.

The way he mentions abstraction here as a competing theory seems to imply something like Averroes’ somewhat reified elaboration of Aristotle’s remarks.

Boulnois is documenting the late 13th-century emergence of an explicit and fully abstract concept of object. It is thus appropriate that he mentions the term “object” only in connection with the transfer theory.

The reference to Scotus “abandoning” the Aristotelian horizon might be to Scotus’s development. The idea that scholasticism as a whole was dogmatically Aristotelian is a prejudice based on misinformation. The most pro-Aristotelian scholastics, like Albert the Great and Thomas Aquinas, incorporate major non-Aristotelian elements. Albert and Thomas themselves were as much Avicennan as Aristotelian, and several other things as well (pseudo-Dionysian?). On a historical level, there was thus no purely Aristotelian horizon to be abandoned. Orthodoxy remained Augustinian, until centuries later when it became Thomistic. In 1277, three years after the death of Aquinas, the elderly and ill Albert the Great felt compelled to travel back from Cologne to Paris to defend Thomas against his anti-Aristotelian critics, who seemed to have the upper hand.

“Now, in the horizon of Avicenna, it is a matter of the production of the object in a new mode of being-represented, which is spiritual and no longer corporeal. The intelligible is no longer in-potentiality for intellection. It exists really in act and as a form. Thus the same term of representation and the concept that accompanies it change their sense. It is no longer a matter of the synthetic presentation of the thing itself in the imagination (in conformity with the etymology of the prefix re-, which on its face indicates a gathering), but of the production of a presentation that takes the place of an absent thing (in the sense in which the prefix re– equally signifies a repetition). Representation is no longer presentation, but reproduction. By reason of the distinction between sensible and intelligible, the form thought is no longer what communicates ‘the common act of the sensing and the sensed’ ” (ibid).

In general, it is by no means obvious that production excludes synthesis. But in this Augustinian-Avicennan context, production is conceived on the model of the creation of something from nothing, whereas synthesis works with pre-existing materials.

Boulnois shows that Henry of Ghent and Duns Scotus developed their original ideas against the background of the Latin Avicenna. He also notes that Avicenna was translated to Latin and much discussed before the major texts of Aristotle were translated. The views about presentation that he mentions as being superseded came from earlier theologians, not from Aristotle.

From the Latin translation of Avicenna through the earlier Franciscans to Duns Scotus, there is a non-Aristotelian, broadly Augustinian tradition that wants to make the intelligible categorically and not just relatively independent of the sensible.

“The support of all intellection is a reality in itself, an absolute entitas [entity]. ‘Intellection is not exclusively a relation.’ And neither the intellect nor the object taken in itself suffices to found the intellection in act. Thus the doubling is complete: ‘Knowledge in the intellect is not immediately caused by the object as exterior, but by something interior […]. For our act of intellection we have an internal object, even though for sensing we have need of an external object.’ We think when we want, even though we do not sense when we want, because a representation of the object is unceasingly present to our intellect by way of memory. Knowledge is not produced directly by the object, but by its representation… The act of knowing is not related to the exterior thing but to an image that resembles it, an imitation in me that corresponds to the thing outside of me” (p. 97).

The explicit concept of an abstract object is a new invention. Once the notion of object is formulated, the sensible thing can be metaphorically called an object as well, and this can come to seem completely natural. But it is the object in memory independent of present sensation that is primary for Scotus. Although the object is new, the active role in constitution that he attributes to memory is Augustinian. Scotus writes as a very original and creative “Avicennizing Augustinian”.

“The representation is no longer a simple resemblance that can refer to many sorts of objects under different angles, like a work of art that signifies in a polysemic manner. The more fundamental model of representation, according to Duns Scotus, is the hoofprint of a horse in the dust of the road: a partial impression that allows the animal that passed by to be recognized, because it includes a partial but precise resemblance to the animal represented” (ibid).

This is emblematic of the transition Boulnois is documenting here. Scotist representation is univocal. The object rises hand in hand with a new notion of strictly univocal representation.

“The trace (vestigium) of the hoof indicates the passage of a horse. The trace is in effect a relation of impression/expression. As the causal impression of the object in a moved body, it expresses the form significatively because it maintains a relation of partial resemblance with the object. Perfect representation will be total representation, the image of the horse, empty or full, under the form of the molding or of the statue. The trace is a partial representation; the total representation will be an adequate image. The trace, although partial, refers to the singular animal, without representing anything common to many individuals. The noetic ideal is that of an exhaustive representation, a very perfect resemblance, a reproduction of all the characters of the object. Representation is not polysemic, but univocal. It is not only a resemblance, but the imitation of a model; it relates to it as one of its copies” (pp. 97-98).

In Roger Bacon’s terminology, as we saw before, the hoofprint is a natural sign. Like all natural signs in this way of thinking, it is the effect of an efficient cause. From it, the passage of a horse can be inferred. To this Scotus adds an insistence on its univocity. Here we are at the veritable sunrise of the object.

“The being of the object in the species, by reason of which the intentio is called spiritual, is only its being as an image, or as a representation, referring to the thing it represents, but at the same time distinguished from it. This being of resemblance is a spiritual being, which does not prevent it from having a material being. As a being of resemblance, of imitation, it does not suppress the material being of the form said properly, that of the sensible species, in the thing itself, in a propagating medium, or in perception. Whether it is a matter of the thing itself or of the phantasm changes nothing. That being there does not have the spirit for its subject. The contents of thought are not identical to mental acts. The order of representation is the law of similitude that organizes all the traits of resemblance. It exercises no physical causality, and does not imply that its subject is intellectual. The order of representation is not related to a spiritualist ontological thesis affirming the existence of an immaterial intellect, but to a pure inscription of resemblance. If knowledge distinguishes between real being and intentional (or diminished) being, it is necessary to abandon the identity of nature between the concept and the object (the principal advantage of the theory of representation)” (p. 98).

The object is here posited as a representation, rather than as a real thing.

“Objective being is characterized by its difference from real being. We have an objective being of the realities that are aimed at, or produced by an operation of intellect, as with all logical intentions. The optical and geometric paradigm is reversed. What intentional being has already become in the era of Duns Scotus is revealed in this switch: intentional being is already a logical and psychological being. Its status is that of the representation of objects and of universals” (pp. 98-99).

“Objective”, represented being becomes the new model for being in general. What is called “real being” no longer plays this role. In this usage, “objective” does not imply “real”.

“Duns Scotus speaks of objective being to designate the status of every object, whether it is a matter of an object of a perception, of a memory, of a concept, of a knowledge, or even of the object of divine prescience. Nonetheless, all these occurrences are articulated around an originary moment, the moment when the perception of the sensible thing is present to the soul and makes the object appear in its form of presence, in its characteristic species, which is to say at first a sensible one. The ulterior moments, of the intelligible in potentiality or in act, or of science, apply to an object already constituted. The only decisive moment is that of the constitution of the object of intellection, indeed before it” (p. 99).

Here “object” is extended to cover this whole space. The presence of the sensible object that leads to the sensible species is associated with an “originary moment”, but then the “only decisive moment” is the constitution of the intelligible object, which is posited to have no dependency on the sensible.

“Objective being is the being of the thing insofar as it is represented, the image of the thing in its mental state. It is the same being (esse) that is considered in the intellect (objective) and as it exists in reality (subjective). There can be a correspondence between the one and the other, but they do not have the same effective status. The one is the other, but according to an intentional or formal identity. Take for example the statue of Hercules: in the marble, Hercules has only an objective or representational being. It is not Hercules, because it is his statue: they do not have the same reality. But it is Hercules, since all his traits are reproduced in it: they have the same form. The objective content of Hercules is indeed present in his representation, on the condition that it is a faithful reproduction. This theory of art as reproductive representation is rather remarkable, and is inscribed in a movement of the longue durée [long term; pun on a key term of the Annales school of history]” (ibid).

This 13th century division into objective and subjective gives each a quite different sense from the later one we are accustomed to. It is not quite a 180 degree reversal on the side of the objective, but it does seem to be on the side of the subjective. Subjective is used in the sense of the Aristotelian hypokeimenon, or what “stands under” something else, which is then identified with what exists in reality, while what is objective is the “content” apprehended by intellect.

“But it is also a theory of intellection. The concept can have an objective content identical to the universal, even if it is formally distinct. The universal is objectively present in it, or again it is represented in it. That is to say it has for content the universal outside of it, to which it refers intentionally. In the cognitive process, it is necessary to distinguish three aspects: the intellect, a real power and efficient cause of the act of knowing; the image or intelligible species, as an accidental form really produced in it; and what the image has for content: the objective being of Hercules. According to objectity, the species is identical to Hercules; according to form, they are distinct” (pp. 99-100).

Again, the term “objectity” is an interpolation. But in any case, objective being now seems to reflect a “content” that is close to the later distinction between content and form; thus the species of Hercules is said to have the same meaningful “content” as Hercules himself, but not to be the same form.

In the conventional terms of the most common reading of form and matter in Aristotle, we would say that the form of Hercules and the form of his statue are the same, while their matter is different. Form in this sense is limited to a visible Gestalt, or what the Latins called a sensible species.

“Presence is said in two senses: the real presence of the object to the power, and then the presence of the object, even if it can be absent, and this presence requires something in which the object shines” (p. 100).

This second “presence of the object, even if it can be absent” is the presence of a representation, which is said to be “objective”.

“The real presence of the object is the real efficient cause of the species in which the object is presented” (ibid).

Again we see the non-obvious association of the first kind of presence with the new Avicennan concept of efficient causality, and with the “action” of the real thing.

“But in this second presence, the presence of the species, the object is the formal cause. The knowable object is not effectively or really present in the intelligible species, but it is like the landlord of the object specified by its representation. Representation has a formal being of presence, while its reference to the corresponding object is of the order of objective being” (ibid).

Here “effective” is treated as interchangeable with “efficient”. From the point of view of the Avicennan and Latin efficient cause, the entire scope of what is really effective is to be explained by efficient causality, which is raised above all other causes. For Aristotle by contrast, it takes all four of his causes to cover the whole field of what is really effective.

“The invention of the concept of objective being and the analysis of representation in terms of the production of an interior word react on one another, and are conjugated for transforming noetics. Knowledge undergoes a change of paradigm. It is not only intentional transitivity that justifies our knowledge of the object. For sure, Thomas Aquinas admits that the known is in that which knows in the mode of the knower: there is an immanence of intellection to the mind that knows. But this being-known does not have a being that is real, proper, and subsistent. It is nothing else than the relation of opening to the thing. Its mode of being is not objective being but relative being: the esse ad, or being with a view to. What is known by the concept is not the thing in its pure quiddity, but the reason for being of the thing (ratio rei): the concept ‘is not that which is thought, but that by which we think, just as the species of color in the eye is not what we see, but that by which we see’. The concept is an invisible mediator, without ontological thickness or proper opacity, where all being consists in separating itself to turn my regard toward the intelligible essence of the thing. Direct transitivity is anterior to the reflection by which we measure our relation to the thing and apprehend it” (pp. 100-101).

This might be the first explicit historical use of the term “concept”. It does not have the same meaning that it does in Hegel or Brandom, where it does have what Boulnois here calls ontological thickness. In the current context, it seems to be a transparent correlate of a representation.

“Direct transitivity” involves the relations by which the object is constituted. We saw above that Scotus wants to put the constitution of objects before any actual thought. Scotist objects are constituted within Augustinian memory, and only appear to Scotist intellect as already constituted. Memory plays the role of the Father in Augustine’s analogy of a trinity in the soul. This always already constituted nature of objects in memory for Scotist intellect plays something like the role of the more “metaphysical” pre-established harmony in Leibniz; of the always already accomplished transcendental-psychological synthesis of imagination in Kant; and of “passive synthesis” in Husserl.

“In the Scotist theory of abstract representation, the species or the word is not only that by which the object is perceived, it is that which the intellect sees or thinks, the representation in which the original is represented and perceived. Moreover objective being, ignored by Thomas Aquinas, implies a mode of being that is restricted but autonomous, which confers on the intentional object an objectivity internal to the mind, that of being represented. The system transposes the consequences of the Avicennan theory of essences into a theory of knowledge. Avicenna, at least in the interpretation of Duns Scotus, distributes a triple mode of being of essences: taken in itself, the essence is a neutrality and an absolute solitude. We can say nothing other that equinitas est equinitas tantum (the essence of the horse is nothing else than the essence of the horse); but the essence can receive existence and become a singular thing by that fact: this horse here or that one there; and finally, it can be universal in my intellect, since it can be attributed to many things. It is the elaboration of a representation that allows the universal to be thought. A representation of the universal, distinct from that of the singular received in the phantasm, is produced in the intellect. It is it that contains the traits common to all the individuals of a species: their universality” (p. 101).

This amphibious character of the intelligible species reflects the dual character of thought, as activity and as content.

The connection here between being an object and universality is an intriguing and original suggestion about the nature of universality. “Representation [as an object] allows the universal to be thought.”

On the other hand, I find the Avicennan idea that an essence is an absolute solitude that simply is what it is, almost unintelligible. In Leibniz something similar is said of the monad, but this is mitigated by the monad’s inclusiveness, by which every monad contains the whole universe from a particular point of view. And in Plotinus, each form in the intelligible realm is said to contain all the others.

“Duns Scotus says that the object has two ways of being present: ‘in itself or in the intelligible species’: either in the direct intuition of its existence, or as the objective correlate of a representation. From the experience of the singular thing, intelligence produces a determinate intelligible — in its being as object, according to Duns Scotus. After the reception of a sensible species, which is related to the singular existent thing, the act of knowing is related to the universal nature, engendered in the intellect according to an esse obiective. ‘What is the reason for the indetermination thanks to which the object that has its first being in the intellect is completely universal? I respond that it is not the thing by itself, since it does not in itself have such an indetermination […] Nor is it the possible intellect, since it cannot receive [an effect] in a way that is more indeterminate than the object can produce. It is the agent intellect, concurrently with a nature that is in some way indeterminate in itself, that is the integral productive cause of the object in the possible intellect according its first being.’ The being of the object is so constituted as to allow intelligible correspondence between the universal in us and the nature that really corresponds to it in the singular thing. Objective being is universal being in the intellect. It has its own proper structure and autonomous reality” (pp. 101-102).

Now the object “in itself” seems to be usurping the primacy of the real thing. Objective being is now said to have an autonomous “reality” of its own. Perhaps Scotus means to say that objective, represented being is more truly or more properly “being” than real being, since the objective is universal and the real is particular.

“The intellect, a real and efficient (but partial and concurrent) cause of the intelligible species, relates to the content as to a veritable thing. As a consequence, it relates to the object without depending on exterior things, without receiving an information from emanated species, other than in a secondary and accidental manner. It represents it independent of its presence or absence, and of the relation of causality induced by that presence. It relates to it intentionally without depending on it causally. The esse obiective of Scotus, by reason of this detachment from the chain of causality resting on the transmission and the denuding of sensible species, opens on another order than the theory of the species expressed by Thomas or Henry of Ghent. By this disengagement, the noetic and logical order no longer depends on the sensory and psychological path of the species. Representation rendering the object present is the seat of an intentionality, of a tending of mental acts toward the represented (the universal). In objective being, representation always renders present an intentional object, whether it really exists or not. It aims at a universal, and this works without the presence of the thing itself” (pp. 102-103).

For intellect, on this account the relational content of a concept plays a role analogous to that played by the sensible thing in perception.

“Thus opens a distinction between intuitive and abstractive knowledge. The knowledge of the object is no longer regulated by the object and the different phases of the intellectual purification of the object. The question of truth as adequation gains a new acuity” (p. 103).

Now the sensible thing — previously contrasted with the object — is referred to (at least by Boulnois) as an object.

Knowledge is no longer regulated by the sensible real thing, but by what I would construe as an integrity or coherence of intentional relations. The odd thing is that this coherence is nonetheless viewed in terms of an adequation or correspondence between knowing and the object.

“Duns Scotus in effect distinguishes two kinds of relation between the act of knowing and the corresponding object. 1) That of measure to measure. 2) That of union with the term with which it is united, which we can also call a relation of attention to the other. They correspond to the distinction between abstraction and intuition. In abstraction, this second relation has no place of being; to know abstractly is to measure. But what is measuring? It is to have, thanks to another thing (measure), a certainty of the determinate quantity of the object. There are two relations of certainty: that of the thing to the intellect where the certainty is produced, and that of the thing to the measure thanks to which the certainty is produced. The last is a real relation, because it is a matter of a comparison of two things, the measure and the measured. Even if it is the intellect that compares them, the measured depends on the measure, according to a real relation between two real things. And since the measured is the object known, and the measure, the measure of knowledge, the dependency passes through two objects: ‘a dependency of the object as known on the object as “that by which it is known”.’ For sure, intellection is the measure of the object by the intellect, which is regulated by it. But the adequation of the measure to the measured is a real relation between two subsistent things. The relation is now deployed in a real, objective, homogeneous space” (ibid).

The relation of measure to measure can be construed purely in terms of “objective” relations like those between commensurable quantities, for example that of a number to another number, which are viewed as determinately subsisting, independent of any act of knowing. But Boulnois glosses this as one of two kinds of relations between the act of knowing and the object.

The mention of “union” with a term on the other hand recalls the inseparability of Aristotelian intellect from what it thinks. This is glossed as the other kind of relation between the act of knowing and the object.

In both cases, it is hard to see how the gloss applies, unless we construe the act of knowing as not presupposing a separable and pre-existing “knowing subject”.

Before, we were contrasting objective being and real being. Now there is mention of a homogeneous space that is said to be both real and objective. This may be related to the idea that the intelligible species, while not depending on any “real” or natural causality, is nonetheless a “real” production by the agent intellect operating as a real efficient cause.

“Here again, the model of light is essential. Aristotle remarked that ‘the agent intellect is like a light’. Light does not cause the object, it reveals it by shining on it. Just as light transforms color in potentiality to color in act, the intellect converts the intelligible in potentiality to an intelligible in act. The object is intelligible in act before intellection. It is only a terminative object, indeed preconstituted. It is the a priori of all thought” (pp. 103-104).

On this model, the agent intellect would “reveal” an object preconstituted in memory, and not be its cause. But then how is this object a “real production”, with the agent intellect as its efficient cause?

“An objection arises. Isn’t it necessary to say that intuition transgresses the limits of abstract representation? That intellect attains the evident knowledge of the object in its very being, without its formal substitute? To this three reasons are opposed: 1) Duns Scotus thinks representation as a preliminary condition of intuitive intellection, indeed as its theoretical sub-basement in the more general order of the functioning of the intellect. 2) The moment of intuition coincides with the production of an expressed species, or of a conceptual word (that is to say a representation that is definitional rather than imagined). 3) This real production can in its turn be preserved in memory: it is not the thing itself. We see that it will be vain to oppose representation (abstract) and intuition (concrete): intuitive intellection is the perception of a representation preliminarily elaborated by memory” (p. 104).

At a very general level, the idea that representation serves as a precondition and substructure for intellectual intuition somewhat resembles Kant’s argument that the very same categories that govern thought also govern the unconscious processes of the synthesis of imagination.

“If the object of perception or of the phantasm is imaginary, the object of an intelligible species is an intelligible object. Objective being is identified with being-represented. What is really engendered is representation, but what it implies, objective being, can be called metaphorically engendered, since it only exists by reference to this, and has a corresponding status. The being of the object is the measure of the being of the representation in the soul: they are of the same nature, phantasm, intelligible species, intellection in act, or acquired science. Thus the being represented in the object and the being of the representation in the soul correspond with and imply one another reciprocally. Objective being is defined as the vis-a-vis of representation, representation as what gathers and constitutes the thing in a unique reason, an object. The object is always the object of a representation, and representation is always representation of an object. The theory of objective being, in insisting on the double ontological status of the object and the representation, reifies representation in a substantial manner. It is not only an act but a thing, and indirectly substantializes the object. The latter is what stably corresponds to the representation, metaphorically engendered by thought” (pp. 104-105).

“Rooted in the medieval debate between Augustinianism and Aristotelianism, the Scotist analysis of knowledge opens up major ontological consequences. The production of sensible images obeys the laws of perspective: every body immersed in light imprints on the eye its resemblance, the sensible species. To explain perception, a certain Augustinian tradition (Henry of Ghent, Olivi) refuses to admit a total and direct causality of the object on the sense. Thomas Aquinas on the contrary showed the necessity rejected by Henry and Olivi. In renewing the doctrine of intelligible species while maintaining the autonomy of the intellect faced with the sensible, Scotus produces a new synthesis. Added to the singular representation of the sensible species, the intelligible species integrates a part of sensible causality, but becomes a real reproduction of the object in the soul. Thus for Scotus, being in general is attained by the point of view of the ‘objective being’ produced by the agent intellect — as represented being” (p. 105).

Thus being in general is reduced to the univocal and represented being of objects.

Back to beginning of this series: Being and Representation Revisited

A Proliferation of Powers

In the 18th century, Voltaire would famously caricature the scholastic emphasis on powers in his claim that for them, opium puts people to sleep because it has a “dormitive power”. Voltaire saw this as an obviously ridiculous tautology that doesn’t explain anything.

The widespread scholastic tendency to see causes as reified “powers”, however, is also implicitly an important counterpole to the bad idea of generalized occasionalism that makes God directly responsible for everything, which is much worse in its consequences than the reification of powers. Any view that sees many reified powers is inherently in conflict with the claim that all power whatsoever is concentrated in a single point, be it God or the emperor. I also think the claim that there is only one real “cause” conflicts with any reasonable interpretation of the meaning of “cause”. Something like this is implicit in Aristotle’s critique of pre-Socratic claims about the One.

The very notion of a human intellective power also seems to rule out the possibility that human understanding could be merely passive in any simple or univocal way. In the previous post we saw that many of the Franciscans asserted a kind of psychological “occasionalism” in the theory of knowledge that — because it is limited in scope, and also treats the individual human intellect as a kind of power — would seem to implicitly conflict with the emphatically unlimited character of the generalized occasionalism that treats all power and causality other than God’s as illusory.

In Duns Scotus the conflict is a bit different. As Boulnois says below, Scotus asserts that there is in part a real causality of the object on the human mind, thus rejecting the psychological occasionalism of his Franciscan peers who denied this. But like them he also aims to follow Augustine in seeing the individual human as having an active intellective power. And at the same time too, he is a radical voluntarist who defends a radical version of omnipotence. An important question will be, how can Scotus (or anyone) be a radical theological voluntarist who also defends radical omnipotence, and not be an occasionalist?

Boulnois continues, “Representation implies a doubling of species. But it also presupposes a continuity of the cognitive activity. For Scotus, as for Olivi, knowledge is the union of two partial concurrent causes, the soul (principal cause) and the body (derived cause). But in his eyes, this is a different model from simple occasionalism: it is necessary to distinguish that which Olivi confused. There is indeed a real causality of the object. [quotes from Scotus:] ‘What is it to excite the intellective power to think: to produce something in it, or not?’ ‘The knowledge engendered in the intelligence is something new, and must have a cause, which is not the soul alone.’ Thus it is necessary to move beyond all the forms of Franciscan occasionalism” (L’Être et représentation, pp. 79-80, my translation throughout).

The emphasis on the production of something recalls the new and original (Avicennan rather than Aristotelian) paradigm of efficient causality as a kind of production, which seems to have been introduced into the Latin-speaking world by Gundissalinus’ 12th-century translation from the Arabic of the great Iranian polymath. This came before the Latin world gained access to the major works of Aristotle. It greatly influenced the development of Latin philosophical vocabulary. Thus Avicenna would help shape the views not only of the anti-Aristotelian Franciscans but also of Aristotle’s defenders Albert the Great and Thomas Aquinas.

The preeminent example of this kind of production would be God’s act of creation, but at the same time this view sees efficient causes in the world as providing examples of production everywhere. Only God is said to truly create from nothing, but the real production of some effect becomes the general model of what it is to be a cause.

A natural cause in this view is also more than the minimalist “reason why” the becoming of things goes this way rather than that, in the determination by reasons in nature that is propounded in Aristotle’s hermeneutic physics. The very notion of “physical” undergoes a major transformation. A natural cause becomes a power that is supposed to be active in its own right.

Properly speaking, a cause in the scholastic sense is a power that both does something and explains something. The new perspective of efficient causality shared by most of the scholastics sees such powers everywhere. Though the new theory is not Aristotelian, at least the role it seems to give to “secondary” causes is something Aristotle would have appreciated.

“In sensation, the material and extended object is indicated by a form or sensible species, the material and extended trace inscribed in a material and extended subject — the organ of the sensing body. The phantasm is only spiritual in the Stoic sense: it designates a concrete corporeal breath, an ‘animal spirit’. That is to say that it remains material, and there is nothing intelligible about it. How does it come about that we call it intentional? Is this intentionality the true psychic intentionality? Not for Duns Scotus” (p. 80).

As we have seen before, the whole vocabulary of intentionality also originally comes from the Latin translation of Avicenna. For Avicenna, intentionality indeed belongs to the soul. (In the late 19th century, Franz Brentano revived this term and discussed its scholastic origins. Then Husserl made it central to his version of phenomenology, while rejecting Brentano’s “psychologism” and attributing intentionality instead to a non-psychological “transcendental subjectivity”. More recently, Brandom has argued for a version of intentionality that belongs entirely to the realm of meaning, and is not only non-psychological, but does not especially pertain to a subject in the modern sense at all.)

For Scotus, Boulnois continues, “The phantasm is only a singular and material image of a material and singular object. Its intentionality is the pure fact of resemblance, as a statue of Hercules represent Hercules. And since the image is relative to the original, in that it represents it, we call it intention. Intentional being for the sensible species is nothing other than the fact of being a natural resemblance, which replaces the object and signifies it. The sensible species is an image, but not an image seen (unlike the statue of Hercules, which is seen and understood as representing Hercules); it is not seen as an object, but rather shows itself as ratio cognoscendi [reason for knowing]: it is not the perceptive image that is seen, but the thing itself. The intentional being of the phantasm does not belong to the activity of the intellect: for the latter it is an exterior object, an extended thing, material and composed of parts. That is why it is not the principal cause of thought but a partial secondary cause that in fact supports it, by reason of the present colligantia [combination] of soul and body. But it is to the intellect itself that the principal cause of thought belongs (ibid)”

“The operation of thought presupposes the double activity of the knower and the known. Duns Scotus cites Augustine as a leitmotiv: ‘Knowledge is engendered by the one and the other’. In effect, neither of the two taken separately can be the perfect active principle of intellection. Three reasons prove that the sensible species is necessary, but not sufficient: 1) The sensible accident is not an object more perfect than intellection, because it would have to be more perfect than the intelligible form to be the perfect active principle. 2) For an object equally present to the intellect, a greater effort and a greater attention (intentio ad intelligendum) allow a more perfect intellection to be achieved, which means that the collaboration of the intellect is required. 3) The proper perfection of the human is thinking. This comes about not accidentally but essentially, since the represented object is accidentally present to the soul, in a contingent manner. It cannot by itself imply an essential perfection. But neither is the intellect the perfect principle of intellection, because the two senses of representation are constitutive of its noetic function. The representing resemblance and the act of intellect are two aspects of the same way of relating to the object. [quote from Scotus:] ‘The act seems to be a resemblance proper to the object.’ To know, it is necessary first to perceive a representative resemblance. The species comes from the object, as from an exterior principle, and it depends on it essentially, which is why it is related to it by a relation that founds its very being. Thus the object is not only a cause by accident or a sin qua non of intellection, it is an essential cause of it. Intellection has a double characteristic, like every natural sign: it is caused by the object. It refers to it essentially” (pp. 80-81).

This two-sided view reflects a reading of Augustine that brings him closer to the way I read Aristotle.

“A theory of partial concurrent causes fully applies here. The object and the intellect concur, each actively but partially, in intellection; taken together, they constitute an integral and total active cause. With this condition, it is manifest that the texts of Augustine militate not for a total constitution by the intellect, but for a causality of the object united with that of the intellect. We can say at the same time that the word is engendered by memory, by science in memory, and by the thing known. The word is first engendered by the acquired science in memory, in a first act that suffices for the second act that is the act of intellection. Nonetheless, in this first act of science in habit, the object shines already. It is manifested in the limpid clarity of intellect. But because of this, it is no longer the real cause of actual intellection. The representation in the intellect takes its place. The object is only the term aimed at by this representation, its actual referent. Science is the formal principle of the engenderment of an actual representation. The object is that which ‘shines’ in the principle. Memory is that which contains the principle” (pp. 81-82).

Augustine’s account of the role of memory in thought is quite interesting and original. In some ways it anticipates Husserl’s notion of passive synthesis. Boulnois continues to expound Scotus.

“The phantasm of the common sense makes a representation independent of its presence. The actual presence of sensation is guaranteed by the inscription of a material trace in an organ. But the form of this trace, its configuration, its structure exist only for knowledge. It is not the body that is the total cause of sensation in the soul, but rather more the soul that is the principal cause of sensation, with the collaboration of the object. The resemblance in the soul is not the sensible species received in the corporeal organ, but an intellectual act of knowledge. Every agent by nature has to render similar to itself what it receives, and the object thought is no exception. It renders the intellect similar to itself. The sensible species leads to an immaterial act of knowledge by the soul. The species follows a continuous trajectory, which goes from the information of sense produced by the object perceived, to the act of perception of the object. This perception in its turn is ‘a certain quality’ of the soul, ‘a certain resemblance of the object, undoubtedly more perfect than the previous resemblance, which we habitually call “species” ‘. After a first representation, the sensible species, the act of knowledge is a second representation, distinct but into intellect — intelligible” (p. 82).

Here again we see a significant explicit reference to presence in what Scotus calls the act of knowledge.

“Scotus’ second line of argument is offensive. The intellectual species is necessary, first of all to explain the presence of the object to thought. — The intellect perceives differences that sensation ignores, because the phantasm does not represent them: only the intellect is turned toward the universal and discerns the quiddity of the object. From the individual conditions furnished by the phantasm — quality, quantity, figure, place, time — the intellect separates the notions apprehended in a complex whole. Scotus integrates in this form the discursive work of thought shown by Aristotle. To abstract is to separately form the species that represent each of these elements in the absolute: object, whiteness, figure, etc. The noetic plane reflects the linguistic analysis of predication: the predicate (albus [white]) recalls a substantive quality (albedo [whiteness]) that we can distinctly name. For [quote from Scotus:] ‘the phantasm does not compete with its species’: all that it represents, it represents as singular, in relation to another, and conjointly. When the intellect abstracts, it forms within itself the species representing these notions: species that are separate from one another and that serve for science, having a universal and autonomous object. It allows the object to be apprehended under its essential reason, detached from its accidental characteristics” (pp. 82-83).

Scotus has a very original and interesting account of the origin of universals in a “formal a priori”. We associate this kind of language with Kant, but as Boulnois will point out much later, this is a Scotist motif in Kant that Kant inherits from the Wolffians. But apparently there is no Scotist analogue for the Kantian synthetic a priori.

“Next, the intelligible species is necessary to explain the formation of the universal. Knowledge does not repose on a theory of abstraction, on a denuding of the sensible conditions that particularize the singular thing, finally to release the essence dissimulated under the corporeal accidents. No more are there forms innate in the intellect. The possible intellect does not contain the universal in advance. It is a pure receptivity. Is it therefore necessary to deny universals? Certainly not. ‘From this evidence, that the intellect can think the universal, I take this proposition: “intellect can have an object that is universal in act, present by itself to itself in its reason as object, and naturally anterior to the act of thinking”. From this follows the hypothesis that in this anteriority (in illo priore), there is an object present in the intelligible species, and thus there is an intelligible species anterior to act.’ Duns Scotus rejects an empirical genesis of the universal. He no more admits innate concepts or ideas, and proposes a new theory, that of the objective a priori. Universality comes neither from sensation nor from divine illumination. It is a condition of possibility preliminary to the act of thought, following from the intelligible structure of our intellect itself, because it always aims at an object. This is present, as in Olivi, as object or term of thought. But unlike in Olivi, this presence is the result of a real (but partial) causality of sensation” (pp. 83-84).

Here among the Franciscans we seem to be witnessing the origin of the modern concept of “object”. Again we see it intertwined with presence. Though it is common to see universality associated with intellect, I did not recall the unique way that Scotus explains universality, in terms of what it is to be an object. Further below, he will also say that the universal is the relation of representation to things. Universality is associated with what Scotus will call “objective” being.

“Universality is an a priori structure, anterior to the act of thinking. [quote from Scotus:] ‘The object is anterior in nature to the act. Universality, which is the proper condition of the object as object, precedes the act of the intellect or the act of intellection. It is necessary that the object also be present under this reason [universality], for the presence of the object precedes the act.’ Universality is nothing other than the status of object as object. Objectity is synonymous with universality, since it is detached from the res [thing] in its singularity, its existence, and its mode of presence. For in order that I be able to think an object in act, it is necessary first of all that it be present as object to my thought. There is indeed an a priori to my act of thinking — the object’s objective presence as species or intelligible form” (p. 84).

Again Boulnois uses Heidegger’s term “objectity”. Though it has partial antecedents among his Franciscan peers, this whole line of thought in Scotus is extremely original, and largely developed in opposition to Aristotle. To turn things around and blame this Scotist novelty on Aristotle as Heidegger does is nothing less than an act of violence, and the height of perversity. And again, Heidegger should have been in a position to know better, since he wrote his dissertation on Scotus.

“The agent intellect makes the sensible species an intellectual form like itself, adapted to the subject in which it is received — the patient intellect” (ibid).

Boulnois switches back and forth between “potential” intellect and “patient” or “passive” intellect, probably reflecting the usage in his source materials.

“The agent intellect [quotes from Scotus:] ‘makes the non-universal a universal’. ‘Since the universal as universal is nothing in existence, but only in something that represents it under this or that reason, these words have no sense, unless it is because the agent intellect produces something that represents the universal, starting from what represented the singular.’ The universal is not an existing thing but the relation of representation to things. Thus the imagination presents a particular phantasm to the patient intellect; the agent intellect imprints a form representing all the objects of the same species. The universal, or what comes down to the same thing, the objective being, is ‘a relative being’ (secundum quid), since it is ‘the being of the represented’ in the representation. The Scotist noetics is a theory of transposition. It rests on a chiasm: the material object produces the assimilation of the intellect to its distinctive traits, but at the same time the intellect assimilates the object in making it pass from material nature to spiritual nature. The continuity of traits is engendered by the object; the distinction between natures is maintained by the intellect. Resemblance is made according to the formal being of the thing, difference according to the mode of being of the subject intellect” (pp. 84-85).

“Formal” being is another name for what Scotus calls “objective” being, associated with universality. This again is a very novel concept that is essentially unrelated to form in Plato and Aristotle.

“How is the ‘transfer’ from the sensible species to the intelligible species accomplished? In virtue of the Scotist analysis, it is necessary that the intelligible species be really distinct from the sensible species, that it be the result of an effective causality. But how do we guarantee that it corresponds well with what it represents? Scotus raises the problem in his Questions on Metaphysics: ‘The cognitive power has the task not only of receiving the species of an object, but also of tending by its act toward that object. And the second point is more essential to the power, because the first is only required because of an imperfection of the power. And the object is more principally object, because the power tends toward it, only because it imprints a species. And it is manifest: if God imprinted a species in the intellect, or in the eye, the latter would comport itself in the same way toward the object as now, and its object would be an object in the same sense. But God is not an object, because the power does not tend toward him, and nonetheless it is He who imprinted it.’ Scotus’ solution consists in making intellect the principal cause of intellection, associated with a partial concurrent but secondary cause, the impression of a species in the possible intellect. And the object is only an object insofar as it is aimed at by the act of knowledge, or term of knowledge. It is more essential for it to be the term aimed at than to be the moving principle. We cannot say that the object of knowledge is reduced to its moving cause, the phantasm: ‘The cognitive power must not only receive the species of the object, it must tend by its act toward the object’. Duns Scotus distinguishes the (nonessential) origin of thought from intentional aim, which is essential. It is not necessary to confound the species received from the exterior in the possible intellect to imprint on it the form of the thing, with the intelligible species produced from the interior by the agent intellect, in order to aim at an object, imprinting its reason in the possible intellect. The two acts are indistinguishable in the present state, but their signification is different. Thus Scotus separates two aspects in the species: what comes causally from the thing itself (the formal content), and what comes from the activity of thought (the aim at an object). The empirical reception of a form means less than the structuration of an intellectual a priori, for constituting the object as object of thought” (pp. 85-86).

Amid all the promotion of efficient causes, it is interesting that intentionality here is characterized as an aim that is essential to thought.

“In so doing, Scotus opens another question, which will become essential for Peter Auriole and Ockham: it is no longer necessary that it be the object itself that causes its representation. It could be produced by another, since God has the power to produce this effect. As a consequence, he can cause the representation of a thing in us independent of its existence” (p. 86).

Most of the later Latin tradition adopts the emphasis on existence and causes of existence from Avicenna. But unlike Aquinas, Scotus does not mainly associate being with existence. For Scotus, the mark of univocal being will be none other than representability.

“In admitting an effective causality of sense, Scotus reconciles the noetics of Augustine with those of Aristotle, the intellectuality of the mind with the collaboration of the phantasm, while reducing the latter to the congruent portion. The phantasm is necessary, but it does not suffice to represent the universal. The eidos received in the imagination is imprinted in the possible intellect, and represents its object under this or that aspect (sub ratione repraesentabilis). The phantasm is sensible and singular; it represents nothing but the sensible and the singular. As [the Latin] Aristotle says, ‘the agent intellect is essentially (mere) an active power’. Nonetheless, its act is not abstraction. The agent intellect cannot act on the phantasm to dematerialize it, or denude it of its accidents, for the good reason that it cannot act on the phantasms at all. The agent intellect cannot act directly on the sensible species, without itself becoming extended and material like it. If the product of the agent intellect were [quote from Scotus:] ‘received in the phantasm, the term received would be extended. The agent intellect would be incapable of effecting the transfer from one order (of reality) to another, and the term received would be no better proportioned to the possible intellect than the phantasm itself’. As a consequence, the agent intellect acts in its proper order, and metamorphoses the sensible image into an intelligible one. It is not limited to denuding the sensible image, but gives its status of object to sensation, in producing a reality in the possible intellect. It does not abstract, it transposes into another order” (pp. 86-87).

I have defended the way Aristotle talks about abstraction as exemplifying a careful minimalism that avoids speculation. But to insist on a quasi-literal “denuding” of the sensible image as Averroes does is not satisfying. The idea of a two-sided causality in which both the intellect and the thing play an irreducible role seems more in line with Aristotle’s general attitude and his hylomorphism.

“Finally, the intelligible species explains the birth of science. It is not simply [quotes from Scotus:] ‘a habit acquired from frequent acts, which facilitates [the repetition] of such acts’ but ‘that by which the object is present as intelligible in act, whether it is the intelligible species or something else’. In effect, the species is an anterior condition of knowledge in act, since it permits the passage of an essential power to act. It precedes all actual intellection, all knowledge acquired through repeated acts. This is a formal a priori condition, and not an a posteriori empirical acquisition. Scotus cites as proof the definition of Aristotle: science only occurs in the intellect by a change in the intellect itself. It has [quote from Scotus:] ‘a form by which the intelligible object is present to the intellect — and this form is anterior to the act of intellection, since the proximate power by which someone is capable of thinking is anterior in nature to the act of intellection’. Between the sensible phantasm and the act of intellection an intermediate moment is interposed — the constitution of an intelligible species. This does not come from a divine illumination, but plays the role of a formal a priori” (p. 87).

“Science” here is a state of knowing in the soul. Again I am impressed by Scotus’ denial of both illumination and innate ideas.

“The intellect [quote from Scotus:] ‘cannot apprehend the object without this species’, and reciprocally, the species cannot represent the object under a reason other than that under which it is apprehended. The traits of resemblance are those of the intelligible species. They render it absolute and precise, that is to say distinct from all others. — Broadly speaking, the first active moment of intellection for the agent intellect consists in engendering an intelligible species from the phantasm in the imagination. In effect, that which is present to the intellect is either the intelligible species itself, or a [quote from Scotus:] ‘certain reason under which shines the intelligible in act’, that is to say a representation that has for its referent the objective being of the thing represented. And this representation, says Duns Scotus, ‘to put it briefly, we call an intelligible species’. The intelligible species has passed entirely under the regime of representation. This engendering of a ‘representation’ is a real generation: the representation is a thing produced by the agent intellect, and is distinct from the intellect that contemplates it as the very thing that it reproduces. But at the same time, the object becomes intelligible, from the imaginary thing that it was. For sure, the engendering of the object is metaphorical: it remains the same thing, to which we relate under a different point of view, insofar as it is intelligible, and not insofar as it is sensible. But its objective being (the angle under which it is represented, its very status as a representation) has now changed. ‘Such is the corresponding representation, such is the objective being that the object possesses in being represented.’ The representation’s status is really changed: from a corporeal image, it becomes a spiritual image; from a singular, it becomes universal; from being received, it becomes produced. If we recall that the representation is a signifier, following this transfer it is the same referent that is now aimed at by a different signification, which is the more strict and more rigorous definition of the metaphor. When the representation changes really, the objective being of the represented is subject to a metaphoric transfer” (pp. 87-88).

Conclusion of this series: Sunrise of the Object

Species, Object, Cause of Existence

On a broader arc, we will begin to see here in detail why Heidegger’s claims about “Western metaphysics” are so wrong.

After his fascinating detour on what could legitimately be called the 13-century science of perspective, Boulnois adds another dimension to the dossier of medieval theories of representation, summarizing intricate Franciscan views about sensible and intelligible “species”. Duns Scotus’s defense of intelligible species will distinguish him from his Franciscan colleagues.

Boulnois not only shows strong explicit connections between representation and “presence” in several important medieval authors. His archaeological investigation of the larger conceptual world around Duns Scotus shows specific historical sources in medieval philosophy for what numerous 20th-century writers have taken to be uncritical modern notions of “objects”, and for the reduction of being to objects, which Heidegger claims typifies “Western metaphysics” as a whole.

I’ve long been fascinated by the 14th-century controversies over species. The rather limited modern scholarship that exists on this point most often frames it in terms of a debate between nominalism and realism about universals, understood as competing theories of what kinds of things there are. That is one aspect, but these disputes also deeply involved the theory of knowledge; what might in a very broad sense be called issues in phenomenology; and a kind of psychology, concerned with details of the functioning of the soul in matters of perception and thought.

Indeed in this section Boulnois does not even mention nominalism. But before leaving it aside though, for another angle on the larger picture it is worth recalling that nominalism radicalizes one side of Aristotle’s assertion (often read as a criticism of Plato) that concrete real things have a kind of primacy, and generalities have a kind of secondary status. Modern scholarship has given most of its attention to the nominalism of William of Ockham, who indeed did belong to the Franciscan line that will be discussed here. But Duns Scotus and non-Franciscans like Walter Burley mounted a strong defense of the realist alternative, to which modern scholarship has been less attentive. Realism here is meant not in the ordinary practical sense, but in the sense of an assertion that universals and other beings of reason have a kind of “reality” of their own, even if we do not literally believe in Platonic forms.

Until the last few decades, the study of Latin philosophy was dominated by Thomists who tended to see Aquinas as towering over others, and focused on him as the leading representative of a “moderate realism” that avoids the respective excesses it sees in both nominalism and Platonism. But Thomas came too early to participate directly in the 14th-century debate, and the major defenders of the realist side, like Scotus and Burley, did not visibly appeal to Aquinas.

The American pragmatist Charles Pierce provocatively referred to himself as a “Scotist realist”, but did not write substantially about Scotus, which left his references somewhat mysterious.

Boulnois sets the stage by summarizing relevant views of Aristotle, Augustine, and Avicenna.

“Nonetheless, the vision of an image resides ‘not in the eye, but in one who sees’ [Aristotle, On Sense Perception]. ” (L’Être et représentation, p. 67, my translation throughout).

This is a nice example of Aristotle’s thoughtful minimalism. “One who sees” refers simply to a whole human individual or other living being in ordinary experience. (Living beings are hylomorphic wholes, whose division into soul and body is a derivative abstraction. “Soul” for Aristotle is neither a speculative entity nor an object of faith, but a way of speaking about the life and character of living beings.)

Boulnois continues, “Not only is the theory of representation deployed in the order of signs and that of images, it concerns knowledge. It rejects all the problems of perception in the perceiving subject, and opens up a scission between the object and the form that resembles it in the knowing subject” (ibid).

“Theory of representation” here refers particularly to the 13th and 14th century views he will be discussing.

What is meant by “knowledge” in this passage is not what I call knowledge in the strong sense — a major feature of which is that it can and will explain itself and respond substantively to questionings — but rather a more general and personal kind of “experience” of knowing that is not involved with dialogical challenge.

As to the rejection of problems of perception in this 13th and 14th century tradition, the qualifier “in the perceiving subject” is essential. Insofar as the account of sensible species is mainly causal, the place of questions of interpretation in our experience of sensibles is greatly reduced. But even if we ultimately reject it, this causal account of perception should be recognized as a substantial theoretical development in its own right.

The scission or cut that he speaks of is not unlike the rift between mind and world in the later and better known representationalism of Descartes.

“How is this scission elaborated? How are we to understand the mode of being of each of these two terms [object and form], and how shall we interpret their correspondence?” (ibid).

In future posts, the notion of object introduced here will undergo some very interesting elaborations. Boulnois briefly recalls the elementary account of sense perception in Aristotle.

“In sensation, a mutation intervenes; a new image surges in the soul. Aristotle distinguishes a form and a matter in sensation: ‘For each sensation, it is necessary to know that sensation is the receptor of sensible forms (aistheton eidon) [which Boulnois here, following the Latin, translates as sensible “species”], just as wax receives the imprint of gold or brass, but not as gold or brass’ . By perception, the soul receives the impression of a form or sensible species (eidos), without the matter that it informs, in the place in which it is inscribed originally’ [quoted from On the Soul, book II] (p. 68).”

In this account of sensation and perception, we have a perfectly non-spooky example of a form’s relative independence from matter. I think Aristotle meant “impression” as a kind of metaphor. But taking it more literally allowed the Latin theologians to overlay Aristotle’s metaphor with Stoic-influenced medieval causal accounts of sense perception.

Boulnois turns to the Augustinian context, so important for the Franciscans. Augustine takes orientation from concerns far removed from those of the Stoics, for whom nothing exists apart from body. In the 13th and 14th centuries, these extremely different views were fused together in a series of remarkable syntheses.

“Augustine adopts this remark, but seeks to make it agree with another: since the spirit is immaterial, nothing of the sensible can act on it. It is the soul that perceives, that produces a sensation in itself when it perceives the sensible body. Sensation is neither a brute sensorial shock nor the simple reception of an image, but rather its production by the soul encountering a material object presented by sense. [quote from Augustine:] ‘While the image begins in the mind, this same image is not produced by the body in the mind, but by the mind itself with a stupefying rapidity.’ This suddenness shows that it is not the bodies seen that produce the images in the mind, but indeed the mind in itself, in its intellectual nature. There is no action of the body on the mind, but an autoaffection of the mind by itself. [quote from Augustine:] ‘The soul undergoes something by the very operations [of sensation], and nonetheless it undergoes nothing from the body, but is acted on by itself.’ Just as the soul cannot bring bodies themselves into its spiritual nature, in sensation [quote from Augustine:] ‘it rolls into itself their images, and delights within itself in these images made by itself. It gives them something of its own substance to form them’. The mental image resolves the drama of Narcissus: in the incapacity of possessing the object, the soul produces an image, in which it finds its satisfaction. Unable to play in a complete image of itself, it monetizes this impossible plenitude, coining multiple images where it is with itself. Thus in sensation the soul forms in itself the images of the things known, in order to possess a spiritual equivalent of the same nature as itself. It recovers from the constitutive alienation of the object. This image has for its subject of substantial inherence the soul, and not the bodily organ of sensation” (pp. 68-69).

This influential Augustinian view, which treats perception as an activity of the soul, is the direct opposite of the passivity of sense perception that the Latin tradition attributed to Aristotle. The “other view” preceding Augustine that Boulnois alludes to is presumably that of Plotinus, who was Augustine’s most important philosophical influence.

I think that for Aristotle, the commonly cited passivity of sensation is only a first approximation that — like other seemingly definitive introductory statements in Aristotle, such as the account of substance (ousia) in the Categories — is intended to be superseded upon more thorough investigation, like that for ousia which Aristotle carries out in the Metaphysics. On closer inspection, at the very least the work of synthesis in the “common” sense — which enables us to experience things and the world in coherent and meaningful ways — is active.

“The specific vocabulary of repraesentatio is developed in parallel to this, in the Latin translation of the Treatise on the Soul of Avicenna. Avicenna holds that there is a conservation of sensible species on the plane of imagination: while raindrops succeed one another, singularly and distinctly, sensed separately the one from the others by the external senses, we perceive a continuous line constituted by their series. Thus the common sense or imagination constitutes this straight line in a first perceptive synthesis. It centralizes the forms received by the five senses, thus transposing sensation into perception. But this synthesis is temporalizing: at the moment when the drop falls, the common sense perceives the drop [quote from Avicenna:] ‘as if it found itself there where it was, and also there where it is, and thus it sees a rectilinear extension (distensio recta)’. While the external sense perceives the thing there where it is at a given instant, the common sense constructs a continuity, that is to say an extension that is of the same nature as the temporal extension of the soul (distensio animi according to Augustine). It does not perceive the thing there where it is, but it perceives it in the mode of ‘as if’: as if it were in two distinct places, and in the relation of the two instants, past and present, as between these two places, here and below, in a synthesis that apprehends them as distinct and unifies them in the movement of their dissociation. Because we must call upon a schematism, the objects of sensation pass, but the phantasm retains them in a continuous presence, [quote from Avicenna:] ‘even if the thing that has already passed has been destroyed’. In the fleeting and discontinuous frame of the sensed world, it separates a form, which is not the fixation of the external object, but an ‘as if’, a substitute, a redoubling in continual permanence — a first representation” (pp. 69-70).

In passing, we see here that Avicenna developed a more explicit account of the synthetic functions Aristotle attributes to the “common” sense. This has intrinsic interest in its own right, but I will not pursue it here.

In the Latin Avicenna, “The word [representation] appears in order to describe the apprehension of an external object by the imagination, precisely to distinguish it from the act of thought. Representation governs the status of the image, and indeed of the imagination. This is why it guarantees the separation between intellect and sensible imagination: intellect knows itself, directly and without an organ, as distinct from the imagination, which does not represent itself, but [quote from Avicenna:] ‘only represents an image taken from the senses’. In a remarkable manner, [Avicenna’s Latin translator] Gundissalinus translated numerous Arabic terms that describe the act of imagining by ‘repraesentare‘, as if he wanted to unify the vocabulary of imagination under a single concept. The term designates the action by which the estimative faculty, a sort of first sensible judgment, recalls with a great ‘speed’ (as in Augustine) the forms that are in the imagination, and re-presents them [quote from Avicenna:] ‘in such a way that it is as if it saw the things to which the forms belong’ ” (p. 70).

But for the Latin Avicenna, representation (repraesentatio) belongs to the imagination, rather than to thought, as it will for Scotus.

Avicenna’s neoplatonic rather than Aristotelian view that “intellect knows itself, directly and without an organ”, not only in God but also in the human, was welcomed by Latin Augustinians.

“The encounter of the two Platonisms, those of Augustine and Avicenna, is effectuated at the same time as the translation of the latter by Gundissalinus. But it is above all affirmed in the 13th century, in what Gilson called ‘Avicennizing Augustinianism’. As William of Auvergne underlined, following Augustine: the intellect does not receive material forms, and nonetheless perception depends on the sensible. How is the difficulty resolved? The response is found in occasionalism. ‘New thoughts or dispositions supervene in the intellectual substances’, by sensible ‘occasions or excitations’. Science begins with sensible experience but is not derived from it, since its nature is intellectual. The sensible is a condition sin qua non, but it is not the only principle of knowledge. It is indeed the soul that thinks, but when it applies itself to sensible objects, it passes through the intermediary of images. [quote from William of Auvergne:] ‘Properly speaking, signs do not transmit a light of science, nor the things themselves, but they excite our souls to apply themselves to things.’ There is indeed a transposition of sensible images into intelligible ones, a transposition that is the very status of representation” (pp. 70-71).

This limited “occasionalism” in the account of perception needs to be sharply distinguished from the generalized occasionalism that makes absolutely everything depend in a direct and total way on divine will. It is the total and unqualified character of the latter that effectively abolishes all worldly intelligibility and causality.

“Thomas Aquinas strives on the contrary to explain perception in line with the account in Aristotle: ‘the soul thinks nothing without a phantasm’. Our intellect thinks the forms in sensible images, because it must turn itself toward sensible experience to receive the objects of thought, and to take from it the forms that are thought. Being the instrument of a bodily knowledge, the phantasm also permits the abstraction of intelligible species. The nature of a stone can only be known completely when it is known as existing in the particular. For we apprehend the particular by sense and imagination. [quote from Aquinas:] ‘To know what is in individual matter, but not insofar as it is in such a matter, is to extract a form from the individual matter that the phantasms represent.’ Representation here is simply the relation of substitution and the resemblance assured by the sensible image. The intellect, turned toward this sensible image representing the thing known, abstracts its nature. Thus the intelligible species is necessary; form abstracted from the thing, it allows us to see the intelligible structure of the sensible, and not only its exterior image.”

“Avicennism or Augustinianism? In any case, the Franciscan line rejects intelligible species: the body cannot by itself directly produce anything in the mind, not even a simple and spiritual intelligible species, which suits the simplicity of its subject, since its causality is that of a corporeal and composite being. On the other hand, it is necessary rather to think that the body acts on the soul by way of a natural liaison (colligantia), by an inclination and a formal union toward the soul to which it is related. This concord between the body and the soul, this harmony introduced by the Creator, is such that the action of the one rebounds on the other, so that the diverse powers of the soul concur in one sole and same act. The impression produced in the body arouses a movement in the soul that corresponds to that in the body, but it is only the occasion, since their metaphysical distinction prevents there being causality of the body on the soul. To think the relation between soul and body, the Franciscan school proposed diverse solutions: the object is an occasional cause or exciter [John Peckham and Roger Marston]; or a simple cause sin qua non [Olivi]; or it is limited to inclining the soul to know [Mathew of Aquasparta, Henry of Ghent]. In all these cases, there is no direct causality of the soul or of the body by itself in the production of knowledge. For Olivi, this is explained by a concurrence of two causes of different orders. It is thus that many people row a single boat, adding their forces together, producing one sole and same movement of the boat. [quote from Olivi:] ‘Each collaborates in pulling the boat, yet none is the total cause.’ Knowledge is the occasional union of concordant partial causes, which produce a single effect. The model is also that of carnal union: as in the union of man and woman, the species is engendered in memory following an immaculate [sic] conception; the species [quote from Olivi:] ‘is engendered in the maternal womb of the intellect itself’. The species, engendered in the womb of the intellect, is the fruit of a copulation between memory and intellect” (pp. 71-73).

All the great Franciscan theologians are strong voluntarists, a position I regard as truly horrible in its consequences. But their arguments about perception and intellection are quite subtle and interesting.

“Perception is susceptible to a double interpretation: physical for the transmission of information, phenomenological for sensation; sometimes as the reception of an act coming from a movement, sometimes as total and apperceptive knowledge of an intentionality. — Bacon knows only a multiplication of material species: ‘species are a material and natural being in the medium and in the sense’. These also transmit spiritual qualities (in the material sense of Stoic spiritus), and perceptions [apercues] by the intellect”. [quote from Bacon:] ‘This spirituality is contrary neither to corporeity nor to the materiality we find in material and bodily things’. If the sensible species is the resemblance to the substance that caused it, it transmits the intelligible intentio. [quote from Bacon:] ‘This is why the sensitive soul can perceive the substance by its species.’ Knowledge presupposes that the sense and the intellect are modified by a sensible effect or a material impression. But in the intentional multiplication, it is the form that acts. In this sense, the species is not only material, but spiritual or intentional: it can act on the sense organs and the powers of perception. [quote from Aquinas:] ‘The form is received in the patient without matter, insofar as the patient is rendered similar to the agent according to the form, and not according to the matter. And in this way, the sense receives the form without matter, since the form has being in a different way in the sense and in the sensible thing. For in the sensible thing, it has a physical (naturale) being, and in the sense an intentional and spiritual being’. The sensible, for example color, at first has a natural being in its objects. But it has an intentional being for the soul. The sensible cause produces an intentio; it intentionally engenders a similar [form] in the medium, then in the organ of sight, by an act of illumination. Thus at first the sense considers the external sensibles, then the rational soul perceives the intentiones that are in the imaginative power and that glow in the phantasm [citations to Henry of Ghent]: glowing, shining, appearing; this expression is almost a pleonasm; we cannot separate the brilliance from what is shown in it, the appearance of the form from its appearing, the phainomenon from the phantasma” (pp. 73-74).

As with representation, the vocabulary of “intentions” comes from the Latin translation of Avicenna. “Apperceptive” is a later term, only introduced by Boulnois by way of description.

“How do we articulate a knowledge already constituted by the laws of optics with the functioning of thought? Beyond the reception of the sensible species, subject to the general laws of perspective, how does representation emerge for the thought that receives it? — Henry of Ghent focuses on three problems: 1) ‘color is other than the species of color’; what we know, beyond the sensible species, is color: how do we sustain the claim that the material species transported by the luminous ray is at once a visual image (the species of the color) and the object rendered visible (with its color)? Why redouble the object with its species? 2) ‘The species of color is abstracted by a quasi-real separation, and by a generation or multiplication of the species in the totality of the medium in which they are found, between the thing and the point of the eye where the visual power is exercised.’ But where is the abstraction situated: is it already prefigured by the separation of the material species emitted outside the subject, or must it be accompanied by an intellectual act, which separates the intelligible species from its material substrate? 3) The operation of the intellect in any case produces only the intellection of the universal. How do we guarantee that this universal corresponds to the singular perceived by the sense? And how can the sensible singular act on the intellect, when the sensible cannot act on the intelligible?” (p. 74).

Boulnois’s phrase “knowledge already constituted by the laws of optics” is quite striking. On this account, a kind of “knowledge” in experience comes before thought, and has its own constitution that is independent of thought. This is one way in which the theory of perspectiva will be applied.

Henry of Ghent was the senior theological consultant in the proceedings that led to the reactionary condemnation of 1277 (though he is said to have had reservations about parts of the final version). Here he appears in a more interesting light.

“For Henry, the same representation is at play in sensation and in thought. [longer quote from Henry:] ‘Such is the process of the act of vision: in the first instance, material light falling on a particular material color radiates outside it. Second, abstraction produces a species of the color without matter. Third, the medium by this species provokes an act of vision…. Fourth, the light of the intellect radiates on the particular phantasm, thanks to which the imagination (phantasia) exists in act. And in this way, it abstracts a universal phantasm from the particular. It poses it before the possible intellect, as the proper object that affects it…. [It allows it to know] the universal thing of which it is the species, so that it is not abstracted from this universal thing, but is a particular phantasm abstracted from a particular exterior thing, since in this way it exists as universal.’ Henry starts from the phantasm as sensible, and means to resolve the noetic problems starting only from the particular representation in the phantasm. It is the light of the agent intellect that separates the universality already present in the phantasm.”

“Thus precisely because the sensible species is already a representation, knowledge has no use for intelligible species. Criticizing the analysis of Thomas Aquinas, Henry from the start rejects intelligible species in the beatific vision, then in all knowledge, which generalizes the argument and turns it against Thomas: [quote from Henry:] ‘The presence of the object is the cause of the presence of the species, and not the inverse: in effect, it is not because the species is in the eye that a white object is present, but the inverse; indeed the first representation of the object is not by a species; as a consequence, it is superfluous to posit a species by reason of the presence of the object.’ If we knew only by representations, our knowledge would fall into idealism. The thing itself is presented to sense and intellect; it has no need of a species to mediately take its place” (pp. 75-76).

A strong thematization of presence is here asserted and developed by Henry of Ghent in a direct and explicit way that is quite unlike the implicit dependence on presence that Heidegger tendentiously claims to find already in Aristotle. We will see more indications like this.

“No more does knowledge have need of intelligible species for Olivi. Nonetheless, knowledge is not effectuated by the naked essence of the cognitive power, but through a mediation. If only for rendering an account of memory, it is necessary to posit the retention in sensible memory of remembered species of sensible objects, [quote from Olivi:] ‘as for universal objects, as when someone thinks the general or specific quiddities of sensible things and absent things taken universally. In effect, these sensible things taken universally cannot be represented by an imaginative species’. In all acts of knowledge, sensible and intelligible, [quote from Olivi: ‘a view (aspectus) is required, having for its actual term an object (super obiectum actualiter terminus)…. This is why, when the exterior thing is not itself presented directly for this view (non obicitur aspectui), it is necessary that there be [… in its place] a species in memory, which is only the principle of the cognitive act as a terminative and representative object.’ In the absence of a real object, knowledge turns its regard toward a substituted object, which is not the causal principle of its vision but the term of its view, and which by its triple status of substitute, effect, and resemblance recalls the absent thing. The sensible species takes its place, it represents it, but only as the term of its view and not as a cause” (p. 76).

These are quite sophisticated accounts.

“If the occasion allows the division between sensation and thought to be preserved, representation allows their continuity to be guaranteed, and the transposition of one into the other. Knowledge is not produced by its object. It is rather the object as term that is produced by the soul under the form of a substitute. [quote from Olivi:] ‘For knowledge or thought of absent objects, it is necessary that a species take the place of the object.’ Even if the thing is not present, the object of its view remains, and the species takes the thing’s place: [quote from Olivi:] ‘It is necessary that an image of the thing be made the object of our regard and be its term.’ The substitutive presence of a representation allows the absence of the cause to be made up for. If the object is lacking, a function of presence gives thought its term: [quote from Olivi:] ‘The thought of an absent thing cannot occur without the cooperation of a presented (praesentialis) object’. The power cannot by itself render its objects present, unless it could render them all present, without limit, and make itself equal to God. It receives its determination of a presence, direct or substitutive. [quote from Olivi:] ‘It is necessary that either the object be presented to it, or that it it be represented in an imagination in such a way that the act of knowledge is applied to the object itself or to its image configured or assimilated to it. And this configuration is the specific reason of the act itself.’ The need for presence manifests the constitutive finitude of the human: it is filled by a representation” (pp. 76-77).

In Olivi too, we see a very explicit thematization of presence.

“On [the matter of the existence of intelligible species], Scotus detaches himself from his Franciscan predecessors. While maintaining continuity with the Baconian theory of the sensible species, he renews the intelligible species, which he like Thomas Aquinas judges to be necessary. The presence of the object to thought does not render vain that of the species. [quote from Scotus:] ‘The object relative to a power has in first place a real presence, that is to say such a proximity that it can engender this species in the intellect, which is the formal reason of intellection. In second place, by the species thus engendered, which is an image of its generator, the object is present under its status as knowable, or as represented’ ” (p. 77).

Here we see Scotus too explicitly thematizing presence.

“In a first moment, the form of the intellection by which the object is presented in intuition is already a species. But its matter is the real presence of the object. In a second moment, the species is imprinted in memory: it is the image itself in its status as image that is perceived; the representation is known as such. The species is indeed the cause of the presence of the object, contrary to what Henry of Ghent affirmed: it is the cause of its presence as thinkable, abstract, independent of the existence of the object — the cause of its real status. This thesis is fundamental: it clears the way for a new acceptation of truth as ‘objectity’, since it leads to clearing the way for a double presence of the object — the real presence of the thing, and the objectual presence of the represented. The thing receives a being as object insofar as it corresponds to a representation” (pp. 77-78).

Boulnois’s use of the term “objectity” implicitly recalls some translations of Heidegger’s Objekität. Heidegger not implausibly considers this “objecthood” to be the product of an objectifying attitude, in which an object is presented for a subject as something external (a view that finds its ultimate expression in modern technology).

But Heidegger writes as if he himself were the first to recognize the alienating aspect of a subject-object duality, which is ridiculous. He then proceeds to blame this alienation on a monolithically bad “Western metaphysics” that he claims to trace back all the way to Plato and Aristotle.

There is no greater obstacle to responsible and insightful “historiography” than this kind of sweeping, ahistorical, monolithic negative interpretation.

And ironically, this kind of gesture — which purports to invalidate all previous philosophy with one blow — owes its fashionable status to none other than Descartes, from whose subject-object dualism Heidegger claims to be the only one who can save us.

In an upcoming post, we will see in much greater detail how a concept of objecthood or “being an object” comes to plays a novel, central, and very explicit role in the work of Duns Scotus, on whom Heidegger wrote his dissertation. In light of his early concentration on Scotus, Heidegger should have been in a position to be aware of this. But as far as I know, Heidegger never even mentions the historical role of Scotus and his near-contemporaries in his frequent later allusive, broad-brush denunciations of Western metaphysics.

Boulnois on the other hand sees a great originality in Scotus on this point.

“Scotus’s argument is polemical: the position of Henry is not tenable. According to him, the same sensible representation, presented in the light of the phantasm, represents a singular thing, and in a second light, that of the agent intellect, it represents another, the universal; thus glowworms appear in the light of day as colored objects, and at night as luminous sources. But according to Scotus, the representation, the sensible species, is at first a thing that is presented in its proper light. Without this the same species, if we placed it in different media, would change its nature: in the vibration of the air, it would represent a sound; in the illuminated air, a color. Quite the contrary, there is a ‘unity of the representation and of the object representable by it’: the representation is not simply a thing that would entertain diverse relations to diverse objects, but its relation to this or that object is constitutive of its being as a representation. The same species, that is to say ‘the same representation’, always represents the same representable, and according to the same reason. Put under a greater light, an identical representation represents no other thing, but the same thing more clearly: the same species of black or white better reveals what it represents in the sun than by moonlight; and reciprocally, the glowworm gives rise to two distinct representing species, that of a colored body and that of a luminous source, which represent diverse objective beings, diverse aspects of the same being. We cannot follow Henry, for whom whereas the phantasm reveals a representation of the singular, the light of the agent intellect reveals a representation of the universal. The sensible species represents the singular, and in the light of the agent intellect it represents it more clearly, so the intellect can think it better. But it in no way represents the universal. It never represents the universal qua universal, whatever light illuminates it. It is necessary to produce another representation and another relation of representation to be able to perceive the universal. The remarkable trait of this refutation is its systematic interpretation of the theory of species, sensible or intelligible, in terms of representation. The denuding of the sensible species never allows knowledge of the universal if it is not already given to us as a representation. If with Henry of Ghent we enter into a theory of representation at the level of the phantasm, it is necessary to go all the way and admit a second, intelligible form of representation. Thus we cease to see the phantasm as the appearance of the very nature of the thing. The agent intellect produces an intentional form. It is not limited to bringing to light the content of the phantasm, as Henry believed. And Scotus insists: if we hold absolutely to preserving the vocabulary of illumination, it is necessary to specify that this light is productive, that it is an efficient cause and not the denuding of a formal aspect of the phantasm” (pp. 78-79).

Like Aquinas, Scotus apparently chooses to overlook Aristotle’s clear explanation of what it is to be a “source of motion or change”, and substitutes for it the very non-Aristotelian notion of what came to be commonly called “efficient causality”. This explicitly makes creation the primary model for worldly causality. Where Aristotle emphasizes the diversity of causes of one thing, this dubious application of the creationist model encourages the reifying view that each thing or state of affairs in ordinary experience has one “efficient” cause that is responsible for its being in the sense of existence.

We will see in a moment that the Latin term causa efficiens is already applied to what is called a “cause of existence” in the 12th-century Latin translation of Avicenna. But this has a different meaning in Avicenna, for whom creation is a necessary eternal emanation from the Necessary Being. The mainstream of theologians writing in Latin assumed that God’s act of creation must be understood as free in a very strong sense, and not as governed by any necessity.

For Aristotle, the primary and essential source of motion or change that causes the bronze statue to come to be as what it is, is the art of bronze-casting (Physics book II ch. 3; Metaphysics book V ch. 2). For Aristotle, granted that there is a real production involved, nonetheless the maker of the cast, the one who pours molten bronze into it, and their actions and tools are all merely “accidental” or incidental contributing causes of the real production of the statue, which is due primarily to the art of bronze-casting. Real production is causing something to come to be what it is, or causing it to have the form that it does.

If we were to apply Aristotle’s own concept to the creationist context that Aristotle never considered, the “source of motion” would then be something like God’s wisdom, and more particularly the content of that wisdom. Leibniz would later take this path. But the Latin tradition generally regards the content of divine wisdom as inscrutable to humans.

Avicenna in the Metaphysics section of his great work The Healing (translated to English as The Metaphysics of The Healing) openly claims to have improved on Aristotle’s Metaphysics. For example, Avicenna says that the discussion of these topics should start with God, pointing out that Aristotle does not do this. He proceeds to begin his own work with a very original account of God as the Necessary Being. While usually putting their own notions of God in place of Avicenna’s, his Latin readers welcomed the general idea of starting with God, and of amending Aristotle to refer to the Creator.

In place of what Aristotle prefers to calls the “sources” (archai) of motion and change, Avicenna substitutes what in the Latin translation was called the causa efficiens or “efficient cause” as the cause of a thing’s existence.

Where Aristotle emphasizes that sources of motion and change are usually complex and plural, in this later tradition there seems to be an assumption that the cause of a thing’s existence ought to be simple.

Where Aristotle emphasizes that “cause” is said in many ways, Avicenna, Aquinas, and Scotus effectively assert the preeminence of Avicenna’s cause of existence over all the Aristotelian ones.

The Latins generally follow Avicenna in substituting a non-Aristotelian cause (what would be aitia in Aristotle’s Greek) of existence for what Aristotle prefers to call the arche (“source” in Sachs’s translations) of motion and change. For Aristotle, nature (physis) is the source (arche) of motion and change in natural things. Real production is the coming-to-be of a form.

For Avicenna and the Latin tradition — historically far more influential on this point than the text of Aristotle — real production is causing something to have being in the sense of existence. This is what in Latin was called efficient cause. The preeminent example of real production for the Latin tradition is God as Creator making something from nothing.

Avicenna was translated to Latin earlier than the major works of Aristotle, and the Latin terminology forged by his translator Gundissalinus was then used by later translators of Aristotle.

Ibn al-Haytham

Ibn al-Haytham (ca. 965 – ca. 1040), known to the Latin practitioners of perspectiva as Alhazen or Alhacen, has been called the father of modern optics. The well-documented Wikipedia article says that his seven-volume Book of Optics, which builds on Ptolemy, Euclid, Galen, and Aristotle, was frequently cited by Kepler, Galileo, Huygens, and Newton. I won’t dwell here on his scientific contributions, which were many; what I find especially interesting is his clear articulation of what Helmholtz in the 19th century would call “unconscious inference” in sense perception.

A notable advocate of critical thought, Ibn al-Haytham wrote that “I constantly sought knowledge and truth, and it became my belief that for gaining access to the effulgence and closeness to God, there is no better way than that of searching for truth and knowledge” (quoted, Wikipedia).

“Truth is sought for its own sake … Finding the truth is difficult, and the road to it is rough. For the truths are plunged in obscurity…. God, however, has not preserved the scientist from error and has not safeguarded science from shortcomings and faults. If this had been the case, scientists would not have disagreed upon any point of science” (ibid).

“[T]he seeker after the truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them, but rather the one who suspects his faith in them and questions what he gathers from them, the one who submits to argument and demonstration, and not to the sayings of a human being whose nature is fraught with all kinds of imperfection and deficiency. The duty of the man who investigates the writings of scientists, if learning the truth is his goal, is to make himself an enemy of all that he reads, and … attack it from every side. He should also suspect himself as he performs his critical examination of it, so that he may avoid falling into either prejudice or leniency” (ibid).

“From the statements made by the noble Shaykh, it is clear that he believes in Ptolemy’s words in everything he says, without relying on a demonstration or calling on a proof, but by pure imitation (taqlid); that is how experts in the prophetic tradition have faith in Prophets, may the blessing of God be upon them. But it is not the way that mathematicians have faith in specialists in the demonstrative sciences” (ibid).

José Filipe Silva in “Perceptual Judgement in Late Medieval Perspectivist Psychology” (2017) writes that “Alhacen has an instrumental approach to faculty psychology, in the sense that he is interested in providing an account of visual perception in terms of functions and mechanisms, rather than in terms of faculties. In that sense, he causes a problem to his medieval interpreters who operate … under the framework of Avicennian faculty psychology” (pp. 1-2).

“A primary concern of late medieval philosophy is how things are made available to perceivers in such a way that they are perceived in an accurate manner. Because things cannot be themselves immediately present to the senses, one needs to posit some form of representation that makes things available. Two issues follow from this: the first concerns the nature of these representations, in terms of their power to represent (what they represent), and the second their ontological status in the medium and in the senses, i.e., the kind of existence or being they have” (p. 2).

“[S]ome late medieval authors seem to have become aware of the limitations of an account of cognition that allow us, as finite beings, to build accurate representations of the external world and its objects on the basis of (the processing of) incoming sensory information by our sensory faculties…. Perspectivist optics tries to address these concerns by strengthening the process of producing and certifying the final product, the image of the external thing acquired by visual perception, by rational-like processes — namely by judgment and inference” (p. 3).

” ‘[D]ifferentiation between two greens is not the actual sensation of green’. But this is still perception by sight; or, better, it is a case of seeing (‘it occurs in sight’) while not being ‘the sensation of colour’…. [T]his visual property can only be perceived by comparison (per comparationem) and discrimination (per distinctionem). According to Alhacen, such an operation is accomplished by what he calls the power of discrimination, the virtus distinctiva. The important and original claim is that any instance of visual experience consists of both the perception of the form that is seen and the further act of discrimination, which is the perceptual judgment, e.g., of comparison. A basic distinction is then at play between: (i) perception at first sight (comprehensio solo sensu) [and] (ii) perception by judgment (comprehensio per distinctionem/cognitionem/scientiam)” (pp. 4-5).

I think such a view is also implicit in Aristotle. What distinguishes Ibn al-Haytham in this regard is that he makes it very explicit.

“There is another function of the faculty of discrimination that resonates to a contemporary mind: it can recognize the perceived object without having to go through all its characteristics, provided it has previously encountered that thing…. Alhacen therefore introduces yet another level: (iii) perception by means of reasoning (comprehensio per argumentationem/sillogismum). According to this last type, perception in the robust sense, i.e., as the perception of all properties/intentiones constituting the sensible form, must include what has often been called (unconscious) sensory inference, because the perception of some of those properties is dependent on acquired knowledge and presupposes a process akin to reasoning: the immediate grasping of a conclusion that follows from the premises without knowing the relation of entailment between premises and conclusion. Alhacen notes that, even though structurally it operates in a quasi-rational way, such perception does not qualify as cognition in the full rational sense, because it is not linguistic (it does not make use of words)” (pp. 5-6, citations omitted).

“Once it possesses these forms in its imagination and encounters similar instances of the same kind, or the same individual, the soul performs what Alhacen calls the second type of perceptual intuition, which is perceptual intuition with previous knowledge. In these cases, Alhacen describes how cognition or perception takes place when the form which is being perceived is compared with the form which is stored in the imagination, namely to its similarity to a general or an individual form already acquired. If it ‘fits’/corresponds to the universal form, the cognitive power of discrimination identifies the kind to which the individual now perceived belongs, whereas if it bears correspondence with an individual form, it recognizes the individual thing…. But the process is often swifter, because the power of discrimination is able to recognize an individual or a kind on the basis of distinctive or salient features” (p. 6).

“In other words, before one knows what a thing (‘red’) is, one perceives the difference between that thing and other things, i.e., the difference between ‘red’ and ‘blue’; once the knowledge of ‘red’ has been acquired, one begins to immediately see ‘red’ (quod est color, insofar as it is colour, an instance of perception at first sight) followed by the recognition of ‘red’ as the kind of colour it is (cuiusmodi sit color or the quiddity of the colour red)” (ibid).

“All this is done in an amazingly short time, especially in the case of perception at first sight. In the case of perception by judgement and reasoning, which are slower than perception at first sight, the process is faster if the objects are familiar (‘frequently perceived’) to the perceiver. In this case, the perceiver has a form retained in his/her memory to which it has access, and that can be applied to the identification of the thing present to the senses, rather than having to go through the process of discriminating all the intentions that constitute the object’s sensible form. As Alhacen makes clear, this is possible due to the way these properties are made available and the ‘familiarity’ of the power of discrimination with them. But this comes at a cost, as it means that it can make mistakes, as recognition is a step removed from the actual seeing of the visual form, and is dependent on a complex combinatory process” (p. 7).

“[I]f a thing is well-known by the perceiver, some salient properties are enough for its identification and recognition. If, however, that is not the case, and the thing is unknown, the perceptual system – sensory power plus last sensor plus power of discrimination – must act on the entire spectrum of sensory information in order to unveil all of its intentions or sensible properties. Alhacen calls this perceptual intuition (per intuitionem) or ‘visual scrutiny’. Perceptual intuition is therefore the perception of the form of the visible thing with all its properties that includes discrimination and inference. In order to do so, i.e., to get a better hold of the object, the sensitive power will move the organ of sense to see the object from other viewpoints. This scanning process is automatically initiated as the result of the way the visual system is built (natus est visus)” (ibid).

“Finally, this allows also for a conclusion concerning the active nature of the perceptual process: if it were passive, it would simply be perception at first sight, just receiving the impressions of light and colour. As we can conclude from Alhacen’s arguments, it is not. Perception of the object’s visual form (the assemblage of its properties or intentions) is the result of complex and complementary levels of psychological functions, including discrimination, recognition, and inference” (p. 9).

Perspectiva

Boulnois sees the Arabo-Latin theory of perspectiva or perspective as inducing a new concept of representation, beyond that found in the Augustinian tradition, that becomes very important in scholastic thought. Over several upcoming posts, we will see a rich interplay between historical notions of resemblance and representation. This makes it hard to sustain the simple picture of these as two globally opposed paradigms.

“The theory of representation does not end in an analysis of signs. The image too takes the place of something. Following Roger Bacon, every image is first of all a sign. But every sign is not an image. The step from signification to resemblance must be taken with rigor. Species are the natural signs of objects, which owe nothing to arbitrariness or convention, but signify their object in virtue of a causal necessity, by their very nature and without imposition. That the image is a natural sign, Bacon had established against Aristotle. Nonetheless, the image does not refer to the original in virtue of a simple inference, but ‘by reason of conformity, of the configuration of one thing to another in its parts and its properties, like images, paintings, resemblances, etc., the species of colors, of flavors, of sounds and all things… In the same way, all the things produced by artisanal work are signs of art itself, and of the impressions and resemblances of these things existing in the soul of the artisan’ [quoted from Bacon’s De signis]. Thus while inference is perceived by a complex mental operation, resemblance offers itself to us in a simple perception, as referring to the original that it imitates” (L’Être et représentation, p. 55, ellipses in original, my translation throughout).

The idea that an image is “more” than signification is striking. But at the same time, it is supposed to be something we can simply perceive. The account of perception here makes perception univocally passive in relation to species. (By contrast, whatever passivity of perception there is in Aristotle is not a strong univocal theoretical perspective. His basic account of the five senses treats them as passive. But sensation is not the whole of perception, as his tantalizing remarks about the active role of the “common” sense in organizing perception and experience make clear.)

Aristotle did not have a theory of natural signs, an explicit general theory of resemblance, or a developed theory of perspective. These are scholastic innovations that have both positive and negative characteristics. From another point of view it might be considered good, for example, not to have a theory of natural signs. But particularly the theory of perspective is a significant accomplishment. For now, I’ll follow Boulnois in letting these views speak for themselves.

The mention of inference as “perceived” is striking. Inference here is not so much an act of intellect as an entailment or implication that is, broadly speaking, “perceived” in things.

Conformities between things “in their parts and properties” could begin to sound like the isomorphism that Brandom singles out as distinguishing a new notion of representation in Descartes. The systematic correspondences between geometry and algebra that Descartes famously highlights are rigorous and exact in a way that analogy in general is not, however.

“The description of images goes much further than general semiotics. Beyond the relations of inference, the mind can come to the knowledge of a resemblance, which establishes par excellence the nature of the sign, as Augustine saw: ‘All desire a certain resemblance in signification, such that signs as far as possible resemble the things signified.’ If the sign is constituted in an image, this is by a surplus of sense: the natural sign is more than a conventional sign, but the image in its turn is more than a trace, more than a simple natural sign. In its plenitude, the image does more than refer to a simple signified. It has its proper thickness; multiple and heterogeneous, it resembles what produces it. Beyond the deciphering of semiotic implications, the sense of the image is deployed up to the play of identity in difference. By this, the iconic privilege of resemblance envelops a whole noetic; it requires a new articulation of image and sign, of resemblance and causality, of object and sense.”

This is an impressively positive view of images. Here we are far from Plato’s critique of imitation. We will see the term “imitation” used in a positive way as well.

The association of resemblance with multiplicity, thickness, and heterogeneity in a “play of identity and difference” here is noteworthy. We are accustomed to stereotypes of medieval views as one-sidedly hierarchical in their reference of everything to God.

The connection of resemblance with efficient causality in the halfway modern, non-Aristotelian scholastic sense is another new development.

“Under the name of the theory of representation, it remains to think at once the unity and the division between a semiotics of inferences and a noetics of images. What is an image? In what does the image differ from resemblance?” (p. 56).

“To clarify the status of the image, the Middle Age relies on the Augustinian theory of the forms of correspondence (convenentia). Augustine in effect distinguishes three connected aspects: image, equality, and resemblance. [quote from Augustine, De diversis questionibus:] ‘For where there is an image, there is a resemblance, but not necessarily an equality; where there is an equality, there is a resemblance, but not necessarily an image; where there is a resemblance, there is neither necessarily an image nor an equality’ ” (ibid).

Boulnois further develops this triangular contrast, treating Augustine as representative of earlier medieval Latin thought.

“The image presupposes a productive principle, and reveals a causal dependency. It implies a resemblance, but not an equality, since it can be deficient in relation to the original, and not express all its traits. Thus in the mirror is found an image of the person it “expresses” (expressa est). Nonetheless it does not exclude equality: an image can be adequate. Equality also implies a resemblance, but not an image. Thus two similar (pares) eggs are equal and resemble one another: all the traits of the one are in the other. But they are not images of one another, for neither is taken from the other or is the expression of the other.”

“Finally, resemblance implies neither an image nor an equality. It is a generic particular trait, without expression or adequation; a pure fact, that of having common traits, but in a transversal manner, without depending on a principle. Insofar as it is an egg, every egg resembles all other eggs; but the egg of the partridge, while insofar as it is an egg resembling the egg of the chicken, is neither its image nor its equal” (p. 57).

This “transversal manner, without depending on a principle” again addresses the multiplicity and heterogeneity in resemblance that he commented on earlier.

“This system opposes the image, causal dependency, and resemblance as a transversal fact, but authorizes a combination of the three concepts. It allows relations to be defined between the Father and the Son (image, resemblance, and equality); between God and the human (image, resemblance, without equality); between two individuals of the same species (resemblance, equality, without image); between the original and its reflection in a mirror (resemblance, image, without equality). Trinitarian theology, anthropology, metaphysics of species, noetics of reflection are tied together around this theory of resemblance, which is oriented toward an end: the theology of the image of God in the divine Trinity, the only case where all three properties, image, resemblance, and equality, are present” (ibid).

For Augustine, metaphors of the Trinity abound, and shed light on other knowledge. He famously used an analogy of the interrelation of three faculties he attributed to the mind — memory, understanding, and will — to make it more intelligible to humans.

“For the Son, image of the Father, constitutes a perfect equality of God with himself. And if there is an image implying perfect equality, it is that which characterizes the relation of parent and child; they are identical generically and specifically, and the parent is the principle of the child. [quote from Augustine:] ‘From the parent is taken (expressa) the resemblance of the son, even if we properly call it image, and it can be taken to the point where it is properly called an equality, except that the parent precedes him in time…. But in God the condition of time does not apply…. It follows not only that the Son is the image of God, because he comes from him; not only that he is the resemblance, because he is the image, but again that he is equal to him’ ” (pp. 57-58, ellipses in original).

“More resembling than resemblance, more essential again than the conception, equality is the accomplishment par excellence of the image. Thus the image culminates in the reproduction of the identical. The theology of resemblance is accomplished in a metaphysics of adequation. It is indeed possible to order the world according to degrees of resemblance, to the point where it contracts into the primordial equality of God with himself” (p. 58).

But all this is by way of contrast to the developments of the 13th century. Here Boulnois returns to his major theme of the status and uses of representation. And in a moment, we’ll get to the fascinating subject of perspectiva.

“From Bonaventure to Henry of Ghent, the authors of the 13th century transpose this system of resemblances into more or less accomplished forms of representation. For Thomas, all effects in some measure represent their cause, but in diverse manners. Certain effects ‘represent only the causality of the cause, and not its form, in the manner that smoke represents fire’. These are signs of inference, which represent as a ‘trace’ (vestigium), for the trace shows the passage of something, but not the nature of that which has passed. Others ‘represent the cause according to the resemblance of its form, as the engendered fire represents the engendering fire, and the statue of Mercury represents Mercury’ — and this representation is called ‘image’, because it participates in the same form. The trace, sign of inference, constitutes the first degree of representation. But the image constitutes the second degree, since it implies a community of form. To cover the entire surface of the thinkable is to follow a system of traces and images, starting from the investigation of adequate representation” (p. 58).

“Over a vast surface of signs and inferences, the order of the image is detached by a turning that is proper to it. It is imposed within the vaster framework of an episteme dominated, at the end of the 13th century, by the paradigm of perspectiva. This discipline includes at once a geometrical optics, a theory of vision, and a psychology of perception. It is inscribed progressively in the disciplines of the quadrivium [the part of the liberal arts that includes arithmetic, geometry, music, and astronomy], taught in the faculty of arts. Medieval perspective rests on a certain number of simple principles, deployed by the main Arabic, and later Latin, theoreticians of this discipline: Al-Kindi, Al-Hazen, Avicenna, Robert Grosseteste, Roger Bacon, and John Peckham.”

“1) Light by its nature follows a rectilinear trajectory from its source to its destination, passing closer and closer through the intermediary points in the medium that propagates it. It is possible to interpret the propagation, reflection, and refraction of light according to laws of equal proportionality, the laws of geometry.”

“2) The same law extends from punctual sources to extended objects. In effect, each point of an illuminated or colored object radiates independently following straight lines. Light can integrally transmit an image of the object in each of its points, and thus constitute a coherent figure. This form, species, or resemblance is transmitted by transparent media in act to polished surfaces, from which they are projected. The experience of a dark room proves this: when light passes through a small opening, the image takes the form of the luminous source, and not that of the opening. The luminous rays are transported according to the geometrical laws of figure, color, and all the visual qualities of the object. ‘It is necessary to give all the causes of natural effects by lines, angles, and figures…. A natural agent propagates its power by itself to the receiver, whether it acts on the senses or on matter. This power is sometimes called a species, sometimes resemblance, and this is the same thing’ [quoted from Al-Hazen (Ibn al Haytham), De aspectibus]. Resemblance is emitted by the thing and transmitted by light, according to the laws of geometry.”

“3) In this visible image, the closer the points are to the center of the luminous cone, the more they are affected by the radiation of many points, and the more they receive an intense radiation. This is the phenomenon of the penumbra.”

“4) The eye itself is one optical system among others. Vision is effectuated by images (species) propagated from the visible object to the eye. It is produced by a pyramid of rays that has for its base the object, and for its summit, the eye. The rays penetrate the organ of vision, the lens of the eye; by geometric projection, they give birth to a proportional image of the original, which is precisely the visual impression. The lens effectuates the perception of every object thanks to the perception of each of its points, but the more powerful and efficacious rays are those that are perpendicular to the surface. Thus visual sensation is nothing but the reception of the species induced by the visible according to its proper laws.”

“5) The eye is an organ destined to receive images, and not to form them or to emit a ray that is then reflected by the object. Vision is the reception of the form of colored bodies on the surface of the lens. It is an information, or a faithful passive impression, produced by a real form emitted by the object.”

“6) The form deposited on the lens is transmitted to the brain by the vitreous humor and the optic nerves. The nerves are hollow tubes full of animal spirits, which form a medium capable of conducting by a series of forces the very image of the object (including its color and configuration) to the brain, the stronghold of internal sense. But the final perception takes place after the meeting of the two optic nerves, which superimpose the images from the two eyes in a cavity of the brain. This is the only place where species are no longer propagated in a rectilinear manner. Besides the proper and common sensibles (size, figure, and movement), the species equally transport complex qualities, which are transmitted by sense, but discerned by the intellect” (pp. 58-61).

Bacon’s major work in this area is entitled The Multiplication of Species.

“We underline here that the species are propagated in being multiplied. It is not the same accident that migrates from one subject to another, but its conforming copy. The object engenders the species of light and color in the point adjacent to the transparent medium that surrounds it, which does the same, and so on. The continuous multiplication of species follows the rays issued by all the points of the surface of the object, until it encounters an opaque obstacle: a quality numerically distinct, but specifically identical, is transmitted to the subject immediately adjacent, until it reaches the ultimate receiving subject. The species or resemblances thus transmit the accidents of the object to the eye, where they are impressed. The transmission of the image passes by the actualization of the medium in potentiality (the diaphanous), to the sense organs and the cavities of the brain that house the internal senses. Thus it is the same visible form of the object that is transmitted by the exterior transparent medium and the apparatus of vision (vitreous humor, optic nerve, which constitute a transparent internal medium). The concrete image of the object is neither reversed nor encoded: — it is not reversed, because the rays are refracted by the posterior surface of the lens without intersecting, as distinct from the inverted images in dark rooms; — it not encoded, because it is the same visible image, transported by the diaphanous medium”, that is emitted by the object, received by the lens, transmitted by the optic nerve, and seen in the brain. Medieval perspective is binocular. It applies to moving eyes that can inspect objects part by part, and converge on a mobile observer, capable of evaluating the relative position of objects in relation to her own body.”

“The same geometry governs the propagation of light and the projection of images in all the optical systems: the shadow cast, the dark room, are all subject to the same laws. Perspective is a paradigm that presides over the destinies of the propagation of light, of vision, and of knowledge. It at once furnishes the law of the visible and the content of visual images. It is given for a passive registration of the real, by a natural and necessary reflection. Resemblance is objective; it founds, in the order of nature, the projections of shadows and light, of measures and images. It organizes the regime of representation in the register of the visible.”

“But the paradigm extends beyond optics: the propagation of species follows the same rules for auditory and olfactory species. Thus the objects of perception multiply the sensibles proper to each sense. The propagation of the real species in a physical medium explains the causal effect of the exterior object on the sense organ: the sensible qualities do not act directly on the organs of sense, but at a distance and by the species; then the species are centralized by the common sense, combined and separated by the imagination, to recompose an image of the exterior object. Beyond the visual image, the law of representation governs every sensation, instructs every form of knowledge before governing every species of thought. The species is the immaterial subject of causal activity, which traverses all the media, and which applies its effect as a resemblance of an original efficient cause. Roger Bacon gives expression to the universal principle of causality: ‘Every efficient cause acts by its proper power, which it exercises on the adjacent matter, as the light (lux) of the sun exercises its power on the air…. This power is called resemblance, image, species, and it is designated by many other names…. This “species” produces all action in the world, because it acts on the sense, on the intellect, and on all the matter of the world, to engender things.’ Every cause radiates resemblances. Things operate at a distance in engendering the species that are similar to them, so that nature is a system of similitudes: each point in the world emits a species that expresses it, and the world is constituted by the resonance of all these expressions.”

“Thus the resemblances are not produced by perception, but transported by light, even if no one perceives them. An autonomous structure, similitude organizes nature, founds the general expression of substances, institutes the relation of the world to itself, without necessarily passing through the medium of an act of knowing. Action at a distance, magnetism, the influence of the stars on the earth, the reflection of an image in the mirror, the imitation of God by the human intellect, all these operations are rays of resemblance. By it, the world curves its spirals on itself. Similitude is the new name for the order of the world. The world, garden of resemblances, represents itself to itself” (pp. 61-63).

Now we come to an important distinction.

“Contrary to perspective in the Renaissance, medieval perspectiva does not designate the place of a subjectivity. It does not impose any privileged point of view. Space is an atmosphere in which objects are situated in relation to each other without any common measure, and without the predominance of the eye of the spectator. The order of the visible world is not a symbolic form that determines the proportions between objects, but an attribute of bodies, an immanent structure. Medieval perspective does not have for its object quantifiable extension, but figures and bodies. Olivi thus says that the distance of the object from the eye, which is the index of the position of the object, is not a thing, and does not produce any representation of itself. It is not visible by itself: ‘The quantity of intermediary space cannot be represented by the species of the thing that exists at the end of that space.’ The only representable quantity is that of visible form, and not that of space. Space is only the envelope of bodies and the archipelago of figures, a differentiated, discontinuous system of finite extensions. Space is not a homogeneous form, a continuous quantity, but the emergence of figures, the source of the appearance of similitudes: anisotropic, heterogeneous, it is oriented and centered by the subjects that are emitters of species, in a general heterotopy. In the invisible frame of transparent media, resemblance renders visible, as it were jerkily, the diaspora of the world.”

“The tree of identities and differences comes first of all to find a home in the space opened by perspective. It is this order of resemblance that metaphysics will tighten, replace by its proper convenentia, by an order of congruence, a hierarchized order of identities and differences, where the diverse is unified by a measure of extension that is more vast, generic, transcendental, or conceptual. These resemblances, which go by numerous names — images, resemblances, idols, phantasms, simulacra, forms, intentions, passions — are distributed over three levels:”

“– Perception is a global knowledge of figure, at once a perception of the form of the whole, of the relation of this form to its parts, and of the relations among the parts. [quote from Al-Hazen:] ‘The power to distinguish distinguishes all the forms that come from it. It distinguishes the colors of the parts, the diversity of the colors, and the ordering of the parts among themselves.’ “

“– Knowledge of a species is engendered by its cause. It is indissolubly the effect and the resemblance of the agent on the patient, but without destroying it, without total conversion of its matter. [quote from Roger Bacon:] ‘The patient rests in its specific nature, but it is rendered similar (assimulatum) to the agent by the species.’ The species presupposes a substrate able to receive and be modified by it. All knowledge is a knowledge by species, since in the act of knowing, the soul is rendered similar to what it knows, while remaining substantially identical. Knowing is only an effect of resemblance, an effect induced on the organs of sense, on the internal sense and on the imagination. The matter of the sensory organ and the nature of the sensitive soul are the subjects of the affection constitutive of knowledge. The species representing a thing and the thing of which it is the species have the same specific nature, even if their mode of being differs. The representation by species is again an effect of resemblance. It guarantees the order of the world, and maintains the classification of species.”

“– Intentio. [quote from Avicenna:] ‘Intentio is what the soul apprehends in the sensible, even if the external sense does not apprehend it at first.’ The external sense apprehends the exterior form, but the intentio is perceived by the internal sense. It is thus, says Avicenna, that the lamb apprehends, behind the exterior form of the wolf, its intentio, that is to say the reason why it should be afraid and flee, which the sense cannot do. Intentiones have an ambiguous status: they are at once the res [thing] sent by the object, and the result of an intellectual operation of abstraction. The intentio refers to a thing aimed at (intendere), but it is not itself that thing: imagination can apprehend a thing by an intention when the thing has disappeared. This vocabulary, taken from the Latin translation of Avicenna, refers to the concept, to the form of the essence as secondary substance (mana), but here, in the sense where intentio is definitional form, less perfect and less real than the thing it defines. The species [quote from Roger Bacon:] ‘is called intentio in the common usage of the physicians; they say, in the reason of the weakness of its being in relation to the thing, that it is not truly a thing, but more an intentio of the thing, that is to say a resemblance.’ Sensation, at once global and distinctive, makes particular properties appear, which define the objective aspects of the thing seen. [quote from Al-Hazen:] ‘It distinguishes generally all the intentiones of the thing seen, which appear by vision and by the total form of the thing seen, composed of these intentiones.’ Thus the total form integrates, aggregates for perception many real aspects, which we can separate, analyze in it — the intentiones, which make it the object of an abstraction.”

“The image sensed becomes the image thought. Perception deposits an image, and renders objects present to the mind. This process guarantees a real, causal, connection between mundane reality and concepts. Principle at work in nature and in science, in perception and in the concept, perspective extends to phantasms and concepts, beneath the division between imagination and logical thought. It serves as the model for a whole coherent tradition, which claims a new form of truth, the philosophy and theology of representation. Perspective institutes a physical, perceptive, and noetic correspondence between objects in space and their representation. Perceptive and psychological mechanism, it allows access to the world by an ensemble of images, the representations already produced by the world itself.”

“In the order of natural causality, the sensible species represents the object that caused it. That is why it allows the inverse trajectory: starting from the image, we can infer its object in a probable way, thus building a science. In the order of artificial causality, it signifies (and implies) the art of the artisan, but it resembles naturally, not its cause but the object it represents. If causality goes from the thing to the species, there is a natural relation (at least probable and constant) of resemblance, which goes from the species to the thing. Words and species refer to things: words are not the species of things, because they are imposed arbitrarily, but they engender a species in relation with the thing which the word was imposed to signify. The vocal sound is not caused by the species of the thing (or else there could not be many languages), and it does not signify it directly, but it is coordinated with it, since the one like the other refers in a convergent manner to the thing. Knowledge and signification are two different relations to the thing, but they presuppose one another. The species is a natural sign that is adjoined to the conventional signification of language. The order of resemblance and the order of signification are two distinct pieces, but articulated the one to the other in a system of general semiotics.”

Perspectiva is not only a description of natural causality in the domain of the visible, but the general grammar of resemblance, which institutes the order of things in the register of representation. The order of representation is an objective regularity, universal, determining from outside all the process of perception, of knowledge, and of thought. Law of objective configuration, it builds an ordered, coherent, and finite world. And if the observer belongs to the order of representation, it is as a subject in the in the sense of a receptacle, one support of representations among others: the eye is a subject of representation in the same way as water, air, or the wall in a dark room, for example. If it sees, it is because it is installed in the visible, considering it from a certain place, at the summit of a cone of rays, and bombarded with a bundle of images. It is not a luminous consciousness facing the dazzling tapestry of the visible, for it belongs to the world as one of its parts. Representation brings on the scene the human in the theater of the world” (pp. 63-67).

A Triangular Relation?

In the previous post, we saw a sharply binary model of signifier and signified being applied by Roger Bacon and Duns Scotus. At least in Bacon’s case, this goes hand in hand with a new kind of “direct” realism that aims to deal directly with things in the world, and repudiates the subtleties of the indirect account of knowledge and meaning by way of concepts and the passions of the soul that was broadly shared by Aristotle, Augustine, and Boethius. But Scotus complicates the picture considerably by also promoting a triangular model that includes concepts understood in a certain way. Scotus also argues for a non-psychological approach to concepts.

“Does the sign signify the thing itself or the concept in the soul? — We have said that for Scotus, the great semantic controversy of the Middle Age, more fundamental than any other, is constituted by the following question: Is the vocal sound the sign of the thing or of the concept?” (Boulnois, L’Être et représentation, p. 35, my translation throughout).

“The line of the English Franciscans seems to have developed this theory long before him: for Roger Bacon, linguistic signs have been arbitrarily instituted by humans to directly indicate the things themselves. Words are not related to things by means of a conceptual interpretation. A new, radically non-Platonic way of thinking language arises: instrument of communication, it ‘takes the place of’ (supponit pro) the thing, and not the idea of the speaker. What is more, it exercises a representative function uniquely defined by its capacity to refer to present and existent things. For Roger Bacon, the name signifies solely the thing on which it has been imposed. It can only refer to things (even if it can signify connotata, by inference). But at the same time, there is a relation between the vox [vocal sound] and the species in the soul. The vocal sound is its proper presentification, but it makes the representation of a thing arise in the mind. It makes the thing be conceived, or makes it arise in the soul. Thus the sign in a single gesture refers to the thing and recalls a representation. The vox is not a concept, but a thing that signifies another; it signifies a singular thing in the present, without involving essence, and no longer passes by way of the intellectus to arrive at the res [thing]. There is a sort of collaterality of the sermo [spoken word] and the intellectus that both refer to the res” (ibid).

Scholastic accounts of language typically focus on proprieties of naming. Implicit in this approach is an account of meaning that begins from individual terms. Broadly speaking, this approach has an affinity to modern bottom-up theories of semantics, which aim to put together a picture of the world in a compositional way from individual terms taken as given.

In the early 20th century, Saussurean linguistics developed an alternative approach that treats the signifier in a relational way, such that each signifier is understood in the first instance as identified by its difference from other signifiers, independent of its nominal reference to a signified. This led to an incipient “deconstructive” analysis of individual terms in the broad current of 20th-century European (especially French) “structuralism”, which then came to be explicitly thematized in developments that Anglophone writers came to refer to as “post” structuralist.

From a completely different starting point in a pragmatist reading of analytic philosophy and German Idealism, in the late 20th century Brandom developed an “inferentialist” semantics that begins from whole sentences as the minimal unit of assertion, and focuses on explaining the “material” inferential properties of propositions in terms of normative assessments of proprieties of concrete assertion, rather than in terms of universal formal rules. Brandom understands the meaning of concepts inferentially, in terms of their use or functional role in assertions, and emphasizes the non-psychological character of meaning understood in this way. From this point of view, concepts are not to be identified with individual terms, and instead have a holistic character, such that each concept involves other concepts.

In sharp contrast to both of these as well as to Aristotle and Augustine, Scotus develops his triangular model of signification in a way that aims to be consistent with a primacy of individual things, and with a direct association of words to things.

“[I]n his first commentary on [Aristotle’s] treatise On Interpretation, [Scotus] maintains, like Boethius and Thomas Aquinas, that the vocal sound signifies the concept, which resembles the thing or ‘represents’ it. The vox immediately signifies the species, the representation of the thing in the intellect, but it mediately signifies that which it represents, which is to say the thing itself. But in the second commentary, closer to Bacon, he holds that the vocal sound directly signifies not the conceptions of the intellect, but the thing itself. When Aristotle and Boethius say that the name directly signifies the passions of the soul, it is necessary to understand by this not the concept, or the resemblance in the soul, but the thing that is conceived. This second version is evidently a radical revision of Scotist semantics. It is also the definitive position of the theological works” (pp. 36-37).

“Following Bacon and [Peter] Olivi, Duns Scotus breaks with the Boethian interpretation of signification, but he does so with a nuance, integrating the Aristotelian semantics; the verbal sign (verbum) is directly the sign of both the thing and the concept, but it is in the first instance the sign of the thing, and then the sign of the concept. The sign comes from a direct causality of the thing and signifies it directly. Nonetheless there is a logical anteriority of the concept, for it is on it that the linguistic sign depends. Scotus formulates his response in the vocabulary of his own theory of causality. The concept, the written sign, and the phoneme are all three ordered effects of the same cause: the thing itself…. Writing, the vocal sound, and the concept are signs, situated on the same plane, none of them exercising any causality over the others, and they signify the same signified” (p. 37).

If the sign is in the first instance the sign of the thing, it is difficult to see how the concept can be logically anterior to the relation of sign to thing. But Scotus apparently wants to assert both, and also that the concept is a kind of sign, and that the sign is a kind of thing.

“[T]he word, the concept, and the thing no longer form a series, but a triangle…. The play of natural causes, the weight of institution, and the semantic relation are articulated with one another, but remain autonomous…. The concept is the first, natural effect of the thing itself. It is it that is first of all a sign of the thing, and not the vocal sound or writing. It constitutes the object of logic, an anterior object, more fundamental than vocal sounds, and supposed by them…. If there is a science of things, metaphysics, and a science of words, grammar, logic occupies an intermediary and central place, as the science of concepts” (p. 39).

Scotus wants to give metaphysics a new status as a rational science, in a strong sense that is independent of Aristotle. Meanwhile, he also explicitly rejects Aristotle’s thesis that logic is a tool for clearly expressing meaning and not a science with its own subject matter, which Brandom has recently revived under the name of logical expressivism.

“Noetics studies the concept insofar as it constitutes an aspect of the mind (mens), where it is found as an accident in a subject. Logic, on the contrary, considers the concept as sign, insofar as it refers to a signified. This is the ambiguity of representation: we consider in it either the thing that represents, or the thing that it represents, the being of the representing or the being represented…. Logic is distinct from psychology…. The aim of thought is not reducible to its psychic reality” (pp. 39-40).

Boulnois does not point it out here, but Scotus’s assumption that the concept is in the mind “as an accident in a subject” is directly opposed to Augustine’s strong contention that the mind should not be seen as a subject in which knowledge and love inhere as accidents.

“In this triangle of word, concept, and thing, the concept is described as a sign, and reciprocally the cognitive act is itself a semiosis. Duns Scotus breaks with Augustine and Boethius, who reserve signification to vocal sounds and writing. He participates in what C. Panaccio has called a general movement of ‘semantization’ of thought. Logic, conceived as a rational science, a theory of signs or of ‘signifying reasoning’ (ratio significandi), is no longer a subalternate discipline, concerned with the expression of thought. Because thought is signifying, logic becomes a theory of thought itself. Nevertheless, it does not fall to it to resolve the problem of the place of thought. Concepts are natural signs, not conventional ones: they are combined in propositions according to logical rules, the structure of which subtends all possible oral or written propositions, even if they are not proffered. They constitute the elements of a universal mental language, of a general grammar and of a pure theory of communication. This language is for Duns Scotus a subjacent condition of all oral enunciations and effective writings” (pp. 40-41).

Thus apparently the treatment of concepts as a kind of sign is closely related to the non-Aristotelian idea that logic is a science with its own subject matter.

“But above all, this ideal possibility is real: it is accomplished par excellence in the domain of angelic communication. Angels communicate with the aid of intelligible signs, which is to say pure concepts, without phonetic or graphical support. Each angel directly causes a concept in another, by an immediate communication. It is on this occasion that Duns Scotus formulates a formal theory of pure thought” (p. 41).

If concepts are natural signs and signs are real things, then concepts are real things.

“The sign establishes a double relation. On the one hand, it is the image of the thing that caused it; on the other hand, what is more important, it signifies it: the concept is a real object, which has a natural existence, belonging to a causal chain; but it bears a resemblance to the object it represents. This resemblance is produced by the concurrent double causality of the thing itself and the intelligible species conserved in memory. — Is it necessary to say that the concept preserves the transparency of representation, while the conventional sign loses it? For a concept, does representare signify a ‘resemblance to’, or simply: ‘taking the place of the presence’ of an object, which was already the sense of the word in Peter of Spain? Does the representivity of the concept for the intellect come from its resemblance to real objects, or from its dependence on a cause?” (pp. 41-42).

Given Scotus’s insistence that the sign refers directly to the thing, it is surprising to read that “We cannot pass directly from the representation to the thing” (p. 43). But our act is different from the reference of the sign, so technically there is no contradiction.

“But even in maintaining that the relation of cause to effect is first, Scotus does not go to the point of abandoning resemblance: both are real aspects of intellection. Even if it supposes the causality of the object, semiosis is a complex process that is not reduced to it, since it supposes a play of resemblances. The sign is recognized more than it is produced” (ibid).

In a way, the play of resemblances resembles the mutual dependence of signifiers in the Saussurean tradition.

That the sign is recognized more than it is produced is a nice injection of good sense that stands in obvious tension with the foundation myth of signs as imposed and instituted “at will”. But the user of a sign is usually not its institutor.

“The phoneme homo no longer signifies the concept of the human: like the concept, it signifies the real human, even if it depends on the concept for this. The three forms of signification (formal sign, oral sign, written sign) are parallel, even if their terms are ordered according to a serial dependency. The signification of the concept is a natural relation between the intellect and things. The signified of phonemes and graphemes remains the thing itself, but it depends on a conventional relation.”

“In this Scotus directly opposes Aristotle, for whom the vox is a sound emitted by the mouth of a human being, accompanied by an imaginative representation. Words are not the tools of knowledge, but of communication” (p. 43).

I think that knowledge in Plato and Aristotle (and Hegel and Gadamer and Habermas and Brandom, among others) implicitly has a dialogical (and therefore in part communicative) character. Gadamer has highlighted the dialogical element in Plato and Aristotle. The “communicative reason” elaborated by Habermas involves a dialogical view of knowledge. It is only “monological” conceptions of knowledge that do not involve an element of communication.

“In itself, the written or oral sign is only an ensemble of sounds or letters, which causes nothing more than the knowledge of itself. The imposition of the sign describes the passage from concept to sign, and reciprocally interpretation allows a reascent from the sign to the intelligible concept that subtends it. The process of interpretation follows a trajectory inverse to that of imposition. It is thus a contingent process of association” (p. 45).

“In the moment of imposition, the imposer associates sense and intellect, in relating a perceived name to a conceived thing. In the moment of interpretation, the hearer recalls the relation between the name perceived in the present, and the past thing that she knew more or less distinctly” (p. 46).

I don’t think of interpretation as happening in a moment. It is not only dialogical, but also involves mediation, concepts, and an extension in time. In the same way, only in a very improper sense is jumping to a conclusion a kind of judgment. But Boulnois is summarizing Scotus here, not necessarily asserting this in his own name.

Signification cannot take the place of knowledge. There is no transparency between the sign and thought” (ibid).

Knowledge implies a knower in a way that formal signification does not. But the dialogical expression and elaboration of knowledge is closely interwoven with the dialogical elaboration of signification and meaning.

“But what is it that is signified? The thing, yes, but in what sense of the word ‘thing’? According to [Scotus’s] Questions on On Interpretation, not the thing in its singularity and its existence, but the thing as quiddity [what Aristotle calls the “what it is”], indifferent to singularity and universality, to existence and nonexistence: the thing as it is seen by the mediation of a concept…. According to this semantic, signification is no longer an intelligible correlation between the signifying and the concept” (pp. 46-47).

Indeed, “thing” is said in many ways. Thing as quiddity and thing as object are almost mutually exclusive. I use “object” in a deflationary way as a relative term, as in “the object of”, not as naming something that is assumed to be a free-standing thing in its own right. I don’t actively use the term “quiddity”, but I think of it as a more static and self-contained projection of essence, which in its more proper usages is not something self-contained. Brandom says that a concept is not the kind of thing we could have just one of. I think of essence in a similar way. All articulation is inter-articulation, involving more than one term.

“From now on, signification can be thought independent of the scope of the concept.”

“Linguistic signs signify directly, without passing through the concept. They can signify a thing more precisely than intellect can conceive it. The circulus vini, a sign that indicates the presence of new wine in the inn, causes nothing new in the intellect of the one who perceives it. It is an arbitrary sign, constituted by a convention…. Convention is limited to establishing a relation of reason between two things, two physical realities: the sonorous matter of the phoneme (the vox) and the reality signified (the res). To be valid, this relation-convention supposes the knowledge of the two terms…. A weak and confused knowledge of the thing suffices for us to be able to use a sign, and to signify in a suitable way. We can signify in a way that is more precise than we conceive” (pp. 47-48).

Signification is a “formal” concept, in what seems to be Scotus’s distinctive sense of the term “formal”, which is neither Platonic nor Kantian, and also not to be understood in terms of modern logical or mathematical formalism. The formal status of signification is what allows it to be “more precise” than the knowledge we actually have. But as Hegel reminds us, formal precision (in any of these senses) is not always a virtue when applied to real things.

“Duns Scotus is inspired by the analyses of Olivi to establish a relation between semantic representation and juridical representation, the sign and the law.”

Peter Olivi was another important 13th-century Franciscan, and another strong voluntarist.

“A sign can be speculative or practical. The speculative sign leads to knowledge; it allows a concept of the signified to be formed in the intellect, but its characteristic tells us nothing of its real existence; for example, homo is the sign of a concept, and allows the knowledge of an essence, of a nature in general, whether or not a human exists. The practical sign implies the existence of its signified; it is the sign of an existence, and not of a simple possibility…. Since the practical sign signifies the advent of an effect, and this effect depends on the ordered power (that is to say on the free voluntary disposition) of someone who can cause it, only the author of this effect can give this practical sign certain being. It suffices that the institutor is disposed to regularly produce the signified of the sign she institutes…. Contracts, pacts, and promises are examples. The practical sign pertains to a juridical order instituted by humans. It depends on a law…. The sign belongs to the domain of the will of a free agent, who is self-determining in limiting herself to the order she institutes. This one, in proportion to her political power, can engage in rendering real what she has disposed in the order of signs” (pp. 48-49).

To me it seems preposterous to say that the sign belongs to the domain of the will of a free agent. A sign belongs to a field of reciprocal determination that is independent of anyone’s will. (See also Hegel on Willing.)

“The practical sign is an ordination of power. In this sense, it belongs to the theology of absolute power and ordained power. In Duns Scotus, these two concepts apply to every free agent: absolute power includes all that a free being can effectively do, de facto. Ordained power includes all she can do in conformity to a law, de jure. The institutor is an absolutely free agent, who self-determines freely in choosing this or that order” (p. 49).

An earlier book by Boulnois develops the history of the theology of absolute power and ordained power in detail. A later book treats the history of theological voluntarism in the Latin tradition.

For Scotus “It is will that founds the truth of the practical sign, and not the inverse” (p. 52).

But “there are signs of which we are not the institutors, and that we receive as fully established by an alien will…. We are under the law of signs, and they do not always depend on us” (ibid).
