Aristotle on the Platonic Good

“Philosophy begins with wonder not that there are things rather than not, but that they are as they are” (Gwenaëlle Aubry, Dieu sans la puissance, 2nd ed., ch. 1, p. 33, my translation throughout).

Here Aubry refers to Aristotle’s famous statement in book capital Alpha of the Metaphysics that philosophy begins in wonder. In the 20th century, Heidegger emphasized the question why there is something rather than nothing. Aubry is pointing out that that is not Aristotle’s question at all. As detailed in many posts here, it is the more particular what-it-is of things that Aristotle is mainly concerned to explain.

“Two texts, in Lambda and Nu, echo the critique of capital Alpha, and each time the insistence of Aristotle is the same, in underlining that he is, of all the philosophers, the first and the only to have posed the good as a principle” (ibid).

Of Aristotle’s four causes, the material cause and the source of motion were generally recognized by the pre-Socratics. The Pythagoreans and Platonists added something approximating to Aristotle’s formal cause. But Aristotle insists that even the Platonists made no real use of a concept of that-for-the-sake-of-which, and confusingly treated the good as a formal cause or as a source of motion instead.

In book Nu of the Metaphysics, according to Aubry he says that Plato’s successor Speusippus and the Pythagoreans “agree with the mythologists in seeing the good not as a principle but as an effect of order…. Beyond Speusippus, the allusion is to Plato…; the error of Plato is not in having posed the good as a principle in making it an attribute of the One, but in having made the One itself the principle” (p. 39).

The relevant passage in book Nu says, “Things that come down to us from those who wrote about the gods seem to agree with some people of the present time who say that the good and the beautiful are not sources but make their appearance within the nature of things when it has advanced. (They do this out of caution about a true difficulty which follows for those who say, as some do, that the one is a source. The difficulty is not on account of reckoning what is good to the source as something present in it, but on account of making the one a source — and a source in the sense of an element — and making number out of the one)” (Metaphysics, Sachs tr., pp. 291-292).

Aubry’s point rings true. Elsewhere Aristotle goes on at length about Speusippus’ and the Pythagoreans’ insistence on the central role of number, which gestures in the direction of a formal cause but is actually treated by them more like a kind of material cause. And when Speusippus and the Pythagoreans talk about the One, they seem to literally mean the number one. As Aristotle points out repeatedly, it is nonsense to make the number one the source of all things, and this also doesn’t explain anything.

I myself for many years simply accepted at face value an identity of the Platonic Good with the One as the source of all things, while downplaying the One’s connection with the mere number one, and emphasizing a sort of negative theology in the style of Plotinus, which eliminates all positive attributes of the One. This really just comes down to saying there is a source of all things, while leaving unclear the way in which it is a source. It also assumes the Platonic thesis — rejected by Aristotle — that there is a single form of the Good.

For Aristotle, the good is said in as many ways as being is. What is essential is not this good or that good, but the relevance of value and valuation to all judgment whatsoever and all doing whatsoever. That relevance appears concretely as that-for-the-sake-of-which, or “final” causality. This was Aristotle’s huge innovation.

Aubry reviews Aristotle’s critique of the Platonic Good in both the Nicomachean and the Eudemian Ethics, which focuses on its status as a universal or an Idea.

“Aristotle underlines that there is not a unique science of the Good, but multiple sciences having for their object different goods” (p. 44).

“To the Good as a genus — undiscoverable — and as Idea — useless and void — Aristotle opposes a good that is prakton [practical, in the ethical sense], a good realizable by the human, determined as the first term of a hierarchy of goods and ends, … which the Nicomachean Ethics calls ‘politics’…. If the critique of the Platonic Good leaves open this path, which the Ethics explore, it does not close off that which consists in posing a Good as principle, the relation of which to particular goods remains to be determined, and of the sort that it is neither that of a genus nor of a species, nor that of an Idea to its participants” (p. 45).

Once again, it will be only the causality of that-for-the-sake-of-which and the related details of act and potentiality that truly explain this relation.

The Four Causes Revisited

Previously I abbreviated my account of book capital Alpha of the Metaphysics, focusing mainly on Aristotle’s own remarks about the “knowledge being sought”. The other main content of this book is a discussion of what his predecessors had to say about this question. The bulk of it concerns the pre-Socratics, with mention of the poets who preceded them.

I tend to regard serious philosophy as starting with Plato. By comparison, even though they have interesting things to say, the pre-Socratics seem mostly to just make dogmatic pronouncements in a simplistic way. As Aristotle says, “[W]hile in a certain way all the causes have been spoken of before, in another way they have not been spoken of at all. For the earliest philosophy about everything is like someone who lisps [sic], since it is young and just starting out” (ch. 10, Sachs tr., p. 28).

But Aristotle’s remarks on his predecessors here — including a brief mention of Plato — also give insight into his perspective on what was most original in his own thought.

These remarks are superficially structured around Aristotle’s claim that no one before him made use of all four causes. But implicitly, this historical critique is preparing the way for a much more fundamental point about the overall leading role of that for the sake of which, which parallels his more developed argument about the nature of explanation in Parts of Animals. The treatment here could also be seen as an anticipation of related conclusions about the nature of the first cause, which will not be made explicit until book Lambda.

The very way in which he briefly introduces the four causes here at the beginning of the Metaphysics already has several important nuances:

“[One cause] is thinghood [ousia or “substance”], or what it is for something to be [what it is] (since the why leads back to the ultimate reasoned account, and the first why is a cause and source), another is the material or underlying thing, a third is that from which the source of motion is, and the fourth is the cause opposite to that one, that for the sake of which or the good (since it is the completion of every coming-into-being and motion” (ch. 3, p. 6).

“Causes” are reasons why. The what-it-is (ti esti) of things is their form, but notably he does not use the word “form” here. The word that Plato had used for form (eidos) had a more common usage for the “look” or visible form of a thing, which is nearly opposite to the sense of essence and deeper truth that Plato and Aristotle give to it.

(Hegel’s remarks on the intangibility of truth suggest a relation between this more ordinary usage of eidos and a weakness of the specifically Platonic notion of form, in which the open-ended nature of essence that Plato so well represents in his depictions of Socratic inquiry is compromised by Plato’s conflicting tendency to sometimes suggest that the form of a thing is something that could be simply known once and for all.)

The material or “underlying thing” answers to the superficial sense of “substance” (ousia) as a logical “sub-ject” of properties in the Categories. But Aristotle has already here associated ousia with the form rather than the material. This could be seen as anticipating the argument of book Zeta on the what-it-is of things, in which the “underlying thing” sense of ousia is eventually superseded by that of the what-it-is.

Pre-Socratic philosophy arose in the relatively cosmopolitan environment of the thriving trade centers of Ionia in Turkey. The Ionians formulated various theories positing a material first principle (water for Thales, air for Anaximenes, fire for Heraclitus, “the Unlimited” for Anaximander).

“Of those who first engaged in philosophy, most thought that the only sources of all things were of the species of material” (ibid). “[B]ut as people went forward in this way, their object of concern itself opened a road for them, and contributed to forcing them to inquire along it. For no matter how much every coming-into-being and destruction is out of some one or more kinds of material, why does this happen and what is its cause? … [But since sources of this kind] were not sufficient to generate the nature of things, again by the truth itself, as we say, people were forced to look for the next kind of source. For that some beings are in a beautiful or good condition, or come into being well or beautifully, it is perhaps not likely that fire or earth or any other such thing is responsible…. So when someone said an intellect was present, just as in animals, also in nature as the cause of the cosmos and of all order, he looked like a sober man next to people who had been speaking incoherently beforehand…. Those, then, who took things up in this way set down a source which is at the same time the cause of the beautiful among things and the sort of cause from which motion belongs to things” (pp. 7-9).

This may seem like a very “Hegelian” kind of argument: “their object of concern itself opened a road for them”. But in reality it is Hegel who is being Aristotelian.

“So these people, as we are saying, evidently got this far with two causes out of those we distinguished in the writings about nature, the material and that from which the motion is, but did so dimly and without clarity, rather in the way nonathletes do in fights; for while dancing around they often land good punches, but they do not do so out of knowledge, nor do these people seem to know what they are saying. For it is obvious that they use these causes scarcely ever, and only to a tiny extent. For Anaxagoras uses the intellect as a makeshift contrivance for cosmos production, and whenever he comes to an impasse about why something is necessarily a certain way, he drags it in, but in the other cases he assigns as the causes of what happens everything but the intellect” (ch. 4, p. 9).

He applauds Anaxagoras for bringing intellect into the discussion, but criticizes him for using it mainly as what Brandom would call an “unexplained explainer”. To the extent that Anaxagoras has an implicit theory of the way in which intellect affects other things, Aristotle regards him as treating it as a “source of motion”. But Aristotle notes that it is completely unclear in Anaxagoras how intellect is supposed to be a source of motion. The same goes for Empedocles’ principles of love and strife.

Aristotle will retain an important role for intellect (and love too) as well as the notion of sources of motion, but he decouples these, and develops a different account of each. In both the Physics and the Metaphysics, he ends up tracing sources of motion to potentiality. But meanwhile, the source of motion is also what the Latin scholastics and early moderns called the efficient cause.

It is again vitally important to recognize the order of explanation that Aristotle employs. He explains the operative aspects of “efficient causality” in terms of the more fundamental notion of developed potentiality. He does not explain “potentiality” in terms of efficient causality, and he most especially does not explain potentiality in terms of some passive role in what the scholastics and early moderns understood by efficient causality. Once again, when he is being careful, Aristotle makes it clear that the primary model for this kind of cause is something like the art of building as a developed potentiality, not something immediate like the hammer’s blow or the carpenter’s arm.

Chapter 5 is devoted to the Pythagorean school’s teaching that mathematical things are the sources of all things. This chapter also incorporates remarks on the Eleatic school’s teaching that the One or Being is the source of all things. He treats both of these as partial anticipations of Plato, grouping them together as “the Italians”, since both of these schools were centered in the Greek colonies in Italy.

“After these philosophic speculations that have been mentioned came the careful work of Plato, which in many ways followed the lead of these people, but also had separate features that went beyond the philosophy of the Italians. For having become acquainted from youth at first with Cratylus and the Heraclitean teachings that all sensible things are always in flux and that there is no knowledge of them, he also conceived these things that way later on. And since Socrates exerted himself about ethical matters and not at all about the whole of nature, but in the former sought the universal and was the first to be skilled at thinking about definitions, Plato, when he adopted this, took it up as applying to other things and not to sensible ones, because of this: it was impossible that there be any common definition of any of the perceptible things since they were always changing. So he called this other sort of beings forms, and said the perceptible things were apart from these and all spoken of derivatively from these” (ch. 6, pp. 14-15).

“In a curtailed way, then, and hitting the high spots, we have gotten hold of who happens to have spoken about origins and truth, and in what way” (ch. 7, p. 16). “But about what it is for something to be, and thinghood, no one has delivered up a clear account, but those who posit the forms speak of it most” (p. 17).

Aristotle thinks that Plato came closer to what is needed than any of his predecessors.

“That for the sake of which actions and changes and motions are, they speak of as a cause in a certain way, but they do not say it that way, nor speak of what is so by its very nature. For those who speak of intellect or friendship as good set these up as causes, but do not speak as though anything that is either has its being or comes into being for the sake of these, but as though motions arose from these” (ibid, emphasis added).

We saw that Aristotle understands Anaxagoras as claiming that intellect is a source of motion, in some direct but unexplained way. Aristotle maintains on the contrary that intellect is a cause in what he above called the “opposite” sense of that for the sake of which.

He continues, “And in the same way too, those who speak of the one or being as such a nature do say that it is the cause of thinghood [i.e., of things being what they are], but not that it either is or comes about for the sake of this; so it turns out that they both say and do not say that the good is a cause, since they say it is so not simply but incidentally” (ibid, emphasis added).

Parts of this remark apply to the Pythagoreans (the one) and the Eleatics (the one or being). All of it, including the part about the good, applies to the Platonists. For Aristotle, neither “the one” nor “being” is in its own right a true cause, because neither gives us a specific why for anything. Aristotle’s own notion of the first cause is to be identified neither with Thomistic Being nor with the neoplatonic One. On the other hand, the good is a true cause, because it does give us specific reasons why. These are expressible in terms of that-for-the-sake-of-which. But he also delicately implies that even Plato treats the Good more like a source of motions than a grounding for explanations in terms of that-for-the-sake-of-which. Elsewhere, he says that Plato treats the Good as a formal cause, rather than as that-for-the-sake-of-which. In any case, he clearly thinks that Plato treats the Good as affecting things in some other way than as that-for-the-sake-of-which. The neoplatonists explicitly represent the One or the Good as producing all things. But at this level, the specificity of reasons why things turn out some particular way is completely left behind.

Without a reason why things turn out as they do, for Aristotle there is no true cause. That-for-the-sake-of-which is more preeminently and properly a why than any of the other causes, and for Aristotle this makes it more preeminently and properly a cause than any of the other causes. That is why it seems reasonable to him that the first cause of all should be purely a cause in the sense of that for the sake of which.

The scholastics and the moderns tend to reduce all causes to the notion of efficient cause that they put in the place of Aristotle’s “source of motion”. But for Aristotle, a source of motion is principally a means to the realization of an end, to which it is subordinated. Aristotle ultimately subordinates all other causes to the operation of the good as that for the sake of which. The result is not a total determination or absolute necessity, but rather various hypothetical necessities that can each be realized in more than one way, and that therefore still allow room for genuine contributions to the outcome from secondary causes.

Aristotle’s association of that-for-the-sake-of-which with completion in the earlier quote recalls the way that he elsewhere associates it with actuality, which in the Barnes-edited Collected Works edition of the Physics is translated as “fulfillment”, and which Aristotle closely identifies with entelechy, which also implies completion. Thus, although I don’t recall him ever explicitly saying it, both potentiality and actuality are represented among the four causes, which we could now alternatively list as form, material, potentiality, and actuality. This particular conclusion is new to me, but based on the argument sketched here it seems pretty solid. This has a number of interesting consequences.

For example, with these identifications in hand, we can apply the priority of actuality over potentiality in Aristotle as an alternate reason why that-for-the-sake-of-which is prior to the source of motion.

We can also see another reason why although there is a kind of analogy between the actuality/potentiality and form/material relations, the distinction between actuality and potentiality cannot be reduced to that between form and material. Otherwise, there would be only two distinct kinds of causes, and not the four on which Aristotle insists. This distinction between the two distinctions fits perfectly with Aristotle’s other insistence that nonsensible as well as sensible things can have being in potentiality, whereas only sensible things are properly said to have material.

Long Detour?

I first encountered a thematically important use of the phrase “long detour” in the works of the late Paul Ricoeur, who was especially concerned with problems of interpretation. While keen to avoid any reduction of interpretation to formal or empirical criteria, Ricoeur emphasizes that all sorts of other investigations nonetheless have value for the primary goal of well-rounded philosophical interpretation.

The phrase “long detour” also seems me to strongly characteristic of Hegel’s Phenomenology and Logic.

Even though Ricoeur had deep reservations about the Hegel of mid-20th century scholarship, he nonetheless recognized an affinity between his own concerns and Hegel’s central notion of “mediation”, or non-immediacy as a key to deeper understanding. (When the only Hegel I knew was the Hegel of mainstream mid-20th century scholarship, I used to consider myself an opponent of Hegel. The Hegel who interests me now is much closer to Ricoeur’s fundamental concerns, despite major differences in style.)

“Reflection” was also an important term for Ricoeur, who was a thoughtful reader of both Kant and Fichte. Along with Hegel, he has the rare distinction of combining Kantian values with a serious engagement with Plato and Aristotle. Reflection and mediation both bear witness to an indirectness that is essential in any approach to the highest good and the highest truth.

Joe Sachs writes in his introduction to Aristotle’s Metaphysics that the latter “is a working out of the cryptic claim in Plato’s Republic (509B) that the good is beyond being, and is responsible for both the being of what is and the being-known of what is known. Socrates warns that one cannot see well the greatest of learnable things by means of his images of the sun, the divided line, and the cave, but only by ‘another, longer way around’ (504B). Aristotle’s Metaphysics is that longer way around, not only in its general purpose of uncovering the greatest of knowable things, but also in its particular understanding of the dependence of being on forms” (p. xx).

Hegel on Being

“Being, pure being — without further determination. In its indeterminate immediacy it is equal only to itself and also not unequal with respect to another; it has no difference within it, nor any outwardly. If any determination or content were posited in it as distinct, or if it were posited by this determination or content as distinct from an other, it would thereby fail to hold fast in its purity. It is pure indeterminateness and emptiness. — There is nothing to be intuited in it, if one can speak here of intuiting; or, it is only this pure empty intuiting itself. Just as little is anything to be thought in it, or, it is equally only this empty thinking. Being, the indeterminate immediate is in fact nothing, and neither more nor less than nothing” (Hegel, Science of Logic, di Giovanni trans., p. 59).

“[Hegel] begins the book with a sentence fragment, the linguistic representation of a thought that is, can be, no true thought” (Pippin, Hegel’s Logic of Shadows, p. 188).

“[T]he opening as such is the resolve to attempt to think Being as such…. This is what will fail (or more precisely, will prove itself to be incomplete as a possible thought, and through that failure we learn… the essential discursivity of thought and the first determination of being as such, determinacy, articulability. (This lesson is what Aristotle wants us to learn when he argues that being as such cannot be a highest genus…. This is, I want to claim, the same lesson we are to learn at the beginning of Hegel’s Logic)” (p. 185).

“But the attempted thought of immediate indeterminacy… is a failed thought…. Just thereby, thinking is thinking its failure to be thinking” (ibid).

“We begin in effect… with ‘Father Parmenides‘… Hegel accepts the challenge of the hypothesis, the thought of… ‘indeterminate immediacy’, as his beginning” (p. 184).

“Its determinacy simply amounts to a thing’s distinguishability from what it is not…. And herein lies Parmenides’ famous problem. This would, as noted, appear to commit us to the existence of ‘what is not’…. It does not, of course; this all rests on a confusion between not-being as not being anything, not existing, and being as being other than… as Plato demonstrated in The Sophist” (pp. 185-186).

Socratic Wisdom

“I went to one who had the reputation of wisdom, and observed him — his name I need not mention; he was a politician whom I selected for examination — and the result was as follows: When I began to talk with him, I could not help thinking that he was not really wise, although he was thought wise by many, and wiser still by himself; and I went and tried to explain to him that he thought himself wise, but was not really wise; and the consequence was that he hated me, and his enmity was shared by several who were present and heard me. So I left him, saying to myself, as I went away: Well, although I do not suppose that either of us knows anything really beautiful and good, I am better off than he is – for he knows nothing, and thinks that he knows. I neither know nor think that I know. In this latter particular, then, I seem to have slightly the advantage of him. Then I went to another, who had still higher philosophical pretensions, and my conclusion was exactly the same. I made another enemy of him, and of many others besides him” (Plato, Apology, Jowett trans.).

The greatest wisdom a human can have is to recognize what we don’t really know. This can be a touchy point, because people who think they just know things they imagine to be true usually don’t like to be told otherwise. But in most areas, the best we can aim for is well-founded belief, which is to say belief that is capable of responding resiliently and in good faith to open-ended Socratic questioning or dialogue, and thus is responsive to the space of reasons. (See also The Epistemic Modesty of Plato and Aristotle).

Husserl on Perception

“External perception is a constant pretension to accomplish something that, by its very nature, it is not in a position to accomplish. Thus, it harbors an essential contradiction, as it were. My meaning will soon become clear to you once you intuitively grasp how the objective sense exhibits itself as a unity in the unending manifolds of possible appearances; and seen upon closer inspection, how the continual synthesis, as a unity of coinciding, allows the same sense to appear, and how a consciousness of ever new possibilities of appearance constantly persists over against the factual, limited courses of appearance, transcending them.”

“Let us begin by noting that the aspect, the perspectival adumbration through which every spatial object invariably appears, only manifests the spatial object from one side. No matter how completely we may perceive a thing, it is never given in perception with the characteristics that qualify it and make it up as a sensible thing from all sides at once. We cannot avoid speaking of such and such sides of the object that are actually perceived. Every aspect, every continuity of single adumbrations, regardless how far this continuity may extend, offers us only sides. And to our mind this is not just a statement of fact: it is inconceivable that external perception would exhaust the sensible-material content of its perceived object; it is inconceivable that a perceptual object could be given in the entirety of its sensibly intuitive features, literally, from all sides at once in a self-contained perception” (Husserl, Analyses Concerning Passive and Active Synthesis, pp. 39-40).

Adumbration is something like foreshadowing.

While many of his contemporaries were caught up in the logical empiricist enthusiasm for literal “sense data” as the supposedly rock-solid foundation for knowledge, Husserl was taking an extremely original approach to a more classical view of the inherent limiting and “transcending” features of sense perception, explicitly bringing out implicit characteristics of any possible seeing of physical objects that seem clear as soon as we bring them into focus and reflect on them.

We need not take something like Plato’s refusal to treat sensation as a source of knowledge as a case of repugnance toward physicality. With Husserl’s help we can “see” a more specific grounding of Plato’s view in reasons inherent to the subject matter. Husserl’s exceptionally clear examples in the realm of visual perception also provide a kind of model for understanding something like Hegel’s frequent complaints against “one-sided” points of view.

“When we view the table, we view it from some particular side…. Yet the table has still other sides” (p. 40). “It is clear that a non-intuitive pointing beyond or indicating is what characterizes the side actually seen as a mere side” (p. 41). “In every moment of perceiving, the perceived is what it is in its mode of appearance [as] a system of referential implications…. And it calls out to us, as it were, in these referential implications: ‘There is still more to see here, turn me so you can see all my sides, let your gaze run through me, draw closer to me, divide me up; keep on looking at me over again and again…'” (ibid).

“These indications are at the same time tendencies that push us toward the appearances not given…. They are pointers into an emptiness since the non-actualized appearances are neither consciously intended nor presentified. In other words, everything that genuinely appears is an appearing thing only by virtue of being intertwined and permeated with an intentional empty horizon, that is, by virtue of being surrounded by a halo of emptiness with respect to appearance. It is an emptiness that is not a nothingness, but an emptiness to be filled-out; it is a determinable indeterminacy” (p. 42).

“In spite of its emptiness, the sense of this halo of consciousness is a prefiguring that prescribes a rule for the transition to new actualizing appearances…. This holds time and again for every perceptual phase of the streaming process of perceiving…. There is a constant process of anticipation, of preunderstanding” (pp. 42-43).

“[A]s soon as a new side becomes visible, a side that has just been visible disappears from sight….But what has become non-visible is not cognitively lost for us…. Having already once seen the back side of an unfamiliar object and, turning back to perceive the front side, the empty premonition of the back side now has a determinate prefiguring that it did not have previously” (pp. 45-46).

“The fact that a re-perception, a renewed perception of the same thing, is possible for transcendence characterizes the fundamental trait of transcendent perception, alone through which an abiding world is there for us, a reality that can be pregiven for us and can be freely at our disposal” (p. 47).

Here “transcendence” just refers to the various characteristics of the incomplete perception of spatial objects he is pointing out.

“[W]e see that every perception [implicitly] invokes an entire perceptual system; every appearance that arises in it implies an entire system of appearances” (p. 48). “What is already given to consciousness in a primordial-impressional manner points to new modes of appearance through its halo which, when occurring, emerge as partly confirming, partly determining more closely…. Advancing along this line, the empty intentions are transformed respectively into expectations” (p. 49).

Perception gives us the very opposite of isolated sense data. Every perception is connected to other perceptions.

“If we ask, finally, what gives unity within every temporal point of the momentary appearance… we will also come across reciprocal intentions that are fulfilled simultaneously and reciprocally” (p. 50).

Substance in the elementary sense of something persisting through change emerges from networks of mutually reinforcing cross-references.

“We can never think the given object without empty horizons in any phase of perception and, what amounts to the same thing, without apperceptive adumbration. With adumbration there is simultaneously a pointing beyond what is exhibiting itself in a genuine sense. Genuine exhibition is itself, again, not a pure and simple possession on the model of immanence with its esse = percipi [to be = to be perceived]; instead, it is a partially fulfilled intention that contains unfulfilled indications that point beyond” (p. 56).

“[I]n the process of perceiving, the sense itself is continually cultivated so in steady transformation, constantly leaving open the possibility of new transformations” (p. 57).

Everything we perceive reaches beyond itself, raising new questions.

“We always have the external object in the flesh (we see it, grasp, seize it), and yet it is always at an infinite distance mentally. What we do grasp of it pretends to be its essence; and it is it too, but it remains so only in an incomplete approximation, an approximation that grasps something of it, but in doing so also constantly grasps into emptiness that cries out for fulfillment” (pp. 58-59).

I suggested above that what Husserl illustrates so clearly about visual perception can serve as a model for other things. In particular, I think both facts and beliefs share the perspectival character of visual perception of spatial objects, because they revolve around analogous issues of correspondence with something external.

The very best and most complete facts about anything at best resemble a collection of still views of a tree from different angles, like the sides of the table in Husserl’s example. The virtue of facts is that they are supposed to be individually self-contained, and individually verifiable by correspondence to states of affairs. Even leaving aside all questions of interpretation that tend to unravel this putative self-containedness, by virtue of their isolation all individual facts still remain “one-sided” or perspectival, like individual still views of the tree.

Even the most complete collection or sequence of still views fails to capture the simultaneous many-sided unity-in-diversity of the concrete tree. The real concrete unity of the tree is not factual but teleological and “transcendental”, forever out of reach of a merely factual approach.

If this is true of the best possible facts, I would say it must also be true of the best possible beliefs, because both revolve around a kind of correspondence to states of affairs. The difference is that beliefs are just assertions of correspondence between what we say and what “is”. But to qualify as a fact, an assertion must also be verifiable by correspondence.

But verification by correspondence can only apply to what appears, not to what “is”, so facts only apply to what appears about states of affairs. Facts in effect just are verifiable appearances. They are an instance of what Plato called “true opinion”. They are objects of justified true belief, and potentially of a kind of subjective “certainty”.

Beliefs on the other hand usually reach beyond appearances toward what is, so although they assert a kind of correspondence, they cannot in general be verified by correspondence. Their well-foundedness in the general case has to do with a goodness of reasons. Well-foundedness by reasons falls short of certainty in one way, but it reaches deeper. It is potentially less subject to perturbation, because it does not directly depend on appearances or correspondence.

I think knowledge is something stronger than well-founded belief. Unlike facts and beliefs, I want to say that knowledge in the proper sense has nothing to do with correspondence to something outside itself. Also, well-founded beliefs may depend on assumptions that could eventually be refuted, but “knowledge” in the sense I want to give it does not depend on any assumptions either.

Contrary to common usage, then, I want to say that facts are not knowledge, and even certainty about appearances is not knowledge.

Judgments of correspondence — including beliefs and facts and certainties about appearance — seem to me to be inherently perspectival in the way that Husserl talks about. On the other hand, that rare thing called knowledge, in the way I am using the term, would be immune to perspectival limitations, because it does not depend on correspondence at all. (See also Husserl on Passive Synthesis; Opinion, Belief, Knowledge?; Sense Certainty?; Taking “Things” as True; Berkeley on Perception; Platonic Truth; Everyday Belief; A Criterion for Knowledge?; McDowell on the Space of Reasons; The Non-Primacy of Perception.)

McDowell on the Space of Reasons

John McDowell’s paper “Sellars and the Space of Reasons” (2018) provides a useful discussion of this concept. Unlike Brandom, who aims to complete Sellars’ break with empiricism, McDowell ultimately wants to defend “a non-traditional empiricism, uncontaminated by the Myth of the Given” (p. 1).

McDowell begins by quoting Sellars: “in characterizing an episode or a state as that of knowing, we are not giving an empirical description of that episode or state; we are placing it in the logical space of reasons, of justifying and being able to justify what one says” (ibid; emphasis added).

For Sellars, to speak of states of knowing is to talk about “epistemic facts”. A bit later, McDowell says that Sellars’ epistemic facts also include judgments and uses of concepts that might not be considered knowledge. Not only beliefs but also desires end up as a kind of epistemic facts. McDowell uses this to argue that the space of reasons is a version of the concept of knowledge as justified true belief. I want to resist this last claim.

McDowell points out that knowledge for Sellars has a normative character. Sellars also regards the foundationalist claim that epistemic facts can be explained entirely in terms of non-epistemic facts (physiology of perception and so on) as of a piece with the naturalistic fallacy in ethics.

McDowell cites Donald Davidson’s contrast between space-of-reasons intelligibility and the kind of regularity-based intelligibility that applies to a discipline like physics, but does not want to assume there is a single model for all non-space-of-reasons intelligibility.

He notes that Sellars contrasts placing something in the space of reasons with empirical description, but wants to weaken that distinction, allowing epistemic facts to be grounded in experience, and to be themselves subject to empirical description. “Epistemic facts are facts too” (p. 5). I prefer going the other direction, and saying empirical descriptions are judgments too.

The space of reasons is only occupied by speakers. Sellars is quoted saying, “all awareness of sorts, resemblances, facts, etc., in short all awareness of abstract entities — indeed, all awareness even of particulars — is a linguistic affair” (p. 7, emphasis in original). “And when Sellars connects being appropriately positioned in the space of reasons with being able to justify what one says, that is not just a matter of singling out a particularly striking instance of having a justified belief, as if that idea could apply equally well to beings that cannot give linguistic expression to what they know” (ibid).

“‘Inner’ episodes with conceptual content are to be understood on the model of overt performances in which people, for instance, say that things are thus and so” (p. 8). “What Sellars proposes is that the concept of, for instance, perceptual awareness that things are thus and so should be understood on the model of the concept of, for instance, saying that things are thus and so” (p. 10). All good so far.

To be in the space of reasons, “the subject would need to be able to step back from the fact that it is inclined in a certain direction by the circumstance. It would need to be able to raise the question whether it should be so inclined” (pp. 10-11, emphasis in original). But McDowell says — and I agree — that this is without prejudice as to whether there is still a kind of kinship between taking reasons as reasons, on the one hand, and the purposeful behaviors of animals, on the other.

McDowell acknowledges that the idea that epistemic facts can only be justified by other epistemic facts is easy to apply to inferential knowledge, but rather harder to apply to the “observational knowledge” that he claims should also be included in the space of reasons. For McDowell, observational knowledge is subject to a kind of justification by other facts.

McDowell and Brandom both recognize something called “observational knowledge”, but Brandom thinks that it necessarily involves appeal to claimed non-epistemic facts, whereas McDowell wants to broaden the concept of epistemic facts enough to be able to say that observational knowledge can be justified by appealing only to epistemic facts. I would prefer to say, observational judgments are subject to a kind of tentative justification by other judgments.

McDowell says that acquiring knowledge noninferentially is also an exercise of conceptual capacities. This clearly implies a noninferential conception of the conceptual, and seems to me to presuppose a representationalist one instead. This has huge consequences.

He says that the space of reasons must include noninferential relations of justification, which work by appeal to additional facts rather by inference. But where did those facts come from? In light of Kant, I would say that we rational animals never have direct access to facts that just are what they are. Rather, if we are being careful, we should recognize that we can only consider claims and judgments of fact, which may be relatively well-founded or not. But appeal to claims of fact for justification is just passing the buck. Claims of any sort always require justification of their own.

As an example, McDowell discusses claims to know that something is green in color. As non-inferential justification in this context, he says one might say that “This is a good light for telling the colours of things by looking” (p. 18). That is fine as a criterion for relatively well-founded belief, but that is all it is.

A bit later, he adds, “I can tell a green thing when I see one, at least in a good light, viewed head-on, and so forth. A serviceable gloss on that remark is to say that if I claim, in suitable circumstances, that something is green, then it is” (p. 19).

This is to explicitly endorse self-certification of one’s authority. It is therefore ultimately to allow the claim, it’s true because I said so. I think it was a rejection on principle of this kind of self-certification that led Plato to sharply distinguish knowledge from belief.

As Aristotle pointed out in discussing the relation between what he respectively called “demonstration” and “dialectic”, we can apply the same kinds of inference both to things we take as true and to things we are examining hypothetically. We can make only hypothetical inferences (if A, then B) from claims or judgments of A; we can only legitimately make categorical inferences (A, therefore B) from full-fledged knowledge of A — which, to be such, must at minimum not beg the question or pass the buck of justification.

The great majority of our real-world reasoning is ultimately hypothetical rather than categorical, even though we routinely act as if it were categorical. One of Kant’s great contributions was to point out that — contrary to scholastic and early modern tradition — hypothetical judgement is a much better model of judgment in general than categorical judgment is. The general form of judgment is conditional, and not absolute.

I think it’s fine to include beliefs, opinions, and judgments in the space of reasons as McDowell wants to do, provided we recognize their ultimately hypothetical and tentative character. But once we recognize the hypothetical and tentative character of beliefs, I think it follows that all relations within the space of reasons can be construed as inferential.

I don’t think contemporary science has much to do with so-called observational knowledge of the “it is green” variety, either. Rather, it has to do partly with applications of mathematics, and partly with well-controlled experiments, in which the detailed conditions of the controls are far more decisive than the observational component. The prejudice that simple categorical judgments like “it is green” have anything to do with science is a holdover from old foundationalist theories of sense data.

I would also contend that all putative non-space-of-reasons intelligibility ultimately depends on space-of-reasons intelligibility. (See also What We Saw.)

Opinion, Belief, Knowledge?

There is an empiricist commonplace that identifies “knowledge” with “justified true belief”. This makes knowledge an especially good kind of belief. I regard that as a flat-out category mistake.

I want to suggest that knowledge is not a kind of belief or opinion at all. As usual, I don’t claim to “know” what I “suggest” with some force as interesting or worthy of consideration, so in particular I do not claim to know that knowledge is not belief or opinion. (I am also not trying to say exactly what knowledge is, only to delimit it somewhat.)

What I am doing is recommending a different use of the word “knowledge”, that at minimum distinguishes it from belief or opinion. This is based on the belief or opinion that the belief or opinion that “knowledge is not belief or opinion” is a well-founded belief or opinion.

I read Plato as very sharply distinguishing “knowledge” properly so-called (epistémé) from any kind of doxa (opinion or belief). This would rule out the identification of knowledge with justified true belief.

It is not uncommon, however, to see claims that Plato himself identified knowledge with justified true belief. I will offer a different interpretation of the main relevant passage here. I apologize for using the old Jowett translation, which is easily accessible online.

“Then when the jurors are rightly persuaded of something one could not actually know except by being present — when they judge it, that is, on hearsay, and yet with a true opinion, they judge it without knowledge; even though, if their decision is sound, their persuasion is correct” (Plato, Theaetetus 201).

Ignoring the particular criterion of knowledge mentioned in the example, the essential is that on reflection, we should all be able to agree that there are cases in which we would say that someone has a true opinion without knowledge. So far, this is agnostic to whether or not knowledge is justified true opinion. It just establishes that true opinion in itself is not knowledge.

“When therefore anyone conceives a true opinion of anything without a reasoned statement, his mind is free from error about it, but does not know it; for the man who cannot give and accept a reasoned statement about anything, has not knowledge of it: but when he adds to his true opinion a reasoned statement, he has in addition all that is required to constitute knowledge” (202).

Here it is very important to distinguish between statements about knowledge and statements about someone who has it. What is argued in the above quotation is that the person who has a true opinion and a reasoned statement has what she needs for knowledge.

I would agree that a person who has knowledge can reasonably be said also to believe what she knows. But it does not follow from this that knowledge itself is any kind of belief, or in particular that knowledge is just true belief accompanied by a reasoned statement. Nothing in the argument excludes the possibility that knowledge itself — as distinct from the person who has both knowledge and belief — is tied only to the reasoned statement, and is in itself independent of the person’s belief.

I think this is already sufficient to disprove the claim that this section of the Theaetetus expresses the view that knowledge is reducible to justified true belief.

If knowledge were tied only to the reasoned statement, it would still be true that the person who also had a true belief would have what she needed for knowledge. Again, I don’t mean to say that “reasoned statement” is sufficient by itself to define knowledge, even though I think it gives an important hint. It is worth noting, however, that Plato’s mention of a reasoned statement is more specific than the simple mention of justification.

Also, “truth” is said in more than one way. The kind of truth that could reasonably be said of a belief or opinion is only a correspondence to facts. The kind of truth of principal interest to Plato was very different from this.

I also think there is a broad category of acquaintance that is extremely important to humans, but is different from knowledge. The kind of experience I find interesting is mainly not ephemeral immediate experience, but the more substantial thing that we mean when we say someone is “experienced”. (See also Imagination, Emotion, Opinion; Consciousness, Personhood; A Criterion for Knowledge?; Everyday Belief; Belief is Different from Faith.)

History of Ethics: Plato

Traditional communities, even the most “primitive” known to modern anthropology, have well-defined, generally accepted ways of distinguishing good and bad actions. Hegel called this “ethical substance”.

What I call “ethics” involves a second level, in which the criteria for good and bad are subject to discussion. Here we are not simply laying down the law, but inquiring into the principles that ought to govern distinctions between good and bad. The oldest documented example of this kind of inquiry in our planetary family of cultures is the writings of Plato. How much of the literary character of Socrates in Plato is attributable to the historic Socrates is debated by scholars, but need not concern us here. It is in Plato that we find an actual record of Socratic inquiry. Other so-called “minor Socratic” schools also claimed to be inspired by Socrates, but left no record of critical give and take comparable to what we find in the dialogues of Plato.

Plato clearly recognized the weakness of argument from authority, and put the reasoned examination of principles before the mere fact of anyone’s say-so. He further pointed out that assertions about God’s will and its applicability to real-world cases need to be evaluated as human assertions, on the same footing as others. In discussions about truth, there are no specially privileged assertions or asserters. He set a strong ideal of sincerely seeking knowledge rather than assuming we have it, and by example promoted the modest attitude that humans should avoid making strong claims that human knowledge cannot validate. Many of his most important ideas are only presented as what I call “suggestions”.

Provocatively, Plato suggested that all beings desire the good, and that the Good is the most ultimate formative principle of all things. This reduces evil to ignorance of the true Good. The tendentious claim here is that evil is a kind of lack or defect, and that no one who aims at what is really evil properly understands what they are doing. This gives fundamental ethical significance to knowledge and the quest for better understanding. Treating evil as due to some lack of understanding also suggests a way of forgiving the evil-doer.

For Plato, wisdom and goodness are correlative. Wisdom especially includes the recognition of what we do not know. It is superior to any law. The most wise are the best qualified to govern, but do not want the job and must be coaxed into doing it.

Plato was unconcerned with questions like who decides who is wise, preferring to focus instead on how such judgments should be made. For the latter, he suggested the same kind of free and open dialogue and examination of reasons as for any other questions about truth.

Roots of Action

Returning again to Alain de Libera’s Archaeology of the Subject, de Libera had characterized a typical modern view of human subjectivity in terms of a “subject-agent” that combines the notion of a grammatical subject with that of a cause associated with a kind of “intentions” that are considered to be both mental acts and representations. This is a very specific cultural construct that makes many assumptions. It has acquired a kind of common-sense status, but treating human subjectivity in this way is very far from universally valid.

The common cliché is to call this the “Cartesian subject”, but de Libera’s project is to show that the groundwork for it was actually laid within the Latin scholastic tradition.

My treatment of de Libera’s work has been and will be a sort of journey of discovery; I don’t know in advance exactly where it will end up.

I had begun to look at his treatment of the particular place of Thomas Aquinas in this development. Previously, I have approached Aquinas mainly in terms of his admirable recovery and defense of what I consider to be good Aristotelian principles, and what I take to be his simultaneous divergence from or confusion of some of these that I regard as highly important. So, I felt the need to consult a few sympathetic secondary sources for a view of Aquinas more on his own terms. Now I feel a little better equipped to resume this thread.

It was a commonplace of 20th century Thomism to recommend itself as an alternative to broadly Cartesian views of what it is to be a human being. The contrasting picture de Libera paints is far more intricate and ambivalent. As well as recovering Aristotelian insights, Aquinas took some new steps in a “modern” direction, but many of these were only consolidated by the systematizing efforts of later Thomists. Part of the reason I felt the need to dwell a little on Aquinas was to be better prepared to understand distinctions between Aquinas himself and later Thomistic developments.

“The semantic field of action is nonetheless more complex, its frontiers more porous, when one considers effective usage, the real implementation of the principles mentioned, or when one analyses more finely the lexicon of the authors” (Archéologie du sujet volume 3 part 1, p. 312; my translation).

To begin with, leading 20th century Thomist scholar Bernard Lonergan concluded that a simple distinction between immanent and transitive action is “too rigid” (ibid). Lonergan is quoted (ibid) saying it was later authors who considered it metaphysically irreducible. For Aquinas, agere (to act) has a strong moral sense related to what de Libera calls a “subject of imputation”. In medieval Latin, actio (action) is used to translate both Greek praxis (glossed as moral conduct) and poieisis (glossed as production). Lonergan says Aquinas uses actio sometimes in a general sense that includes both of these, and sometimes more specifically for moral conduct. By contrast, action affecting external matter is more properly called factio.

For Aquinas, actio in the moral sense, according to de Libera’s summary of Lonergan, is associated with “free beings who are masters of their acts” (p. 313). I (and I think Aristotle as well) would say instead ethical beings who are responsible for their acts. Freedom and mastery are here implicitly defined in terms of one another, and ethical being and responsibility are also defined in terms of one another.

As I understand it, Aquinas regarded the will as a function of intellect rather than a separate faculty, so he would not be a voluntarist in the technical sense formulated that way. Nonetheless, as I understand it, he insisted that humans have the equivalent of arbitrary freedom.

I say that responsibility does not involve mastery, nor does ethical being involve freedom to act arbitrarily. This issue is independent of questions connecting action with efficient causality.

Mastery and arbitrary freedom (medieval Latin libertas, or the liberty of the lord to do whatever) are (mis)applications of something analogous to omnipotence on a moral or social level. Early modern apologists for absolute monarchy were strongly committed to an analogy between absolute monarchy and theologies stressing divine omnipotence. For Plato and Leibniz, this was the formula of tyranny. (See also Euthyphro.)
