Aristotle’s Critique of Dichotomy

Chapter 3 of the extraordinarily rich book 1 of Aristotle’s Parts of Animals contains a strong critique of the notion of classification by dichotomy, with implications reaching far beyond its original context. The idea that he criticizes is Platonic division into As and not-As, which is intended to result in a binary tree structure (i.e., a tree-shape in which all the branches are binary).

Platonic division was perhaps inspired by the two-sided character of Platonic dialectic, which was concerned with impartially examining the implications of both sides of some disputable question, particularly in the form of arguments for and against some thesis or other. Aristotle’s own dialectic has a more general form that is not bound to arguments for and against, but rather is simply concerned with an impartial examination of the consequences of hypotheses.

But in any case, classification in a world is a different problem from that of impartially examining a single hypothesis.

Ignoring Aristotle’s lesson, and strongly influenced by the more general impoverished notion of logical judgment as grammatical predication, early modern writers on natural history attempted to follow an a priori theory of univocal classification. But for Aristotle, there is no a priori theory of classification. Instead, the starting point is what Kant would call the implicitly schematized manifold of a concrete world.

Aristotle points out that if classification were reducible to the assignment of predicates, then to consistently classify a world or any given collection, there would have to be some one order in which we divide things by one predicate, then another, and so on. By examples he illustrates the fact that by this method, it is impossible to arrive at the division of animal species that we recognize in nature.

He also makes the more general argument that half of the classifying terms in any classification by sequential predication will be negatives, and that negative terms cannot be properly subdivided.

“Again, privative [negative] terms inevitably form one branch of dichotomous division, as we see in the proposed dichotomies. But privative terms in their character of privatives admit of no subdivision. For there can be no specific forms of a negation, of Featherless for instance or of Footless, as there are of Feathered and of Footed. Yet a generic differentia must be subdivisible; for otherwise what is there that makes it generic rather than specific? There are to be found generic, that is to say specifically subdivisible, differentiae; Feathered for instance and Footed. For feathers are divisible into Barbed and Unbarbed, and feet into Manycleft, and Twocleft, like those of animals with bifid hoofs, and Uncleft or Undivided, like those of animals with solid hoofs. Now even with the differentiae capable of this specific subdivision it is difficult enough so to make the classification that each animal shall be comprehended in some one subdivision and not in more than one (e.g. winged and wingless; for some are both — e.g. ants, glowworms, and some others); but far more difficult, impossible, is it to do this, if we start with a dichotomy into two contradictories. For each differentia must be presented by some species. There must be some species, therefore, under the privative heading. Now specifically distinct animals cannot present in their substance a common undifferentiated element, but any apparently common element must really be differentiated. (Bird and Man for instance are both Two-footed, but their two-footedness is diverse and differentiated. And if they are sanguineous they must have some difference in their blood, if blood is part of their substance.) From this it follows that one differentia will belong to two species; and if that is so, it is plain that a privative cannot be a differentia.” (Complete Works, Barnes ed., vol. 1, p. 1000).

Aristotle’s positive conclusion is as as follows:

“We must attempt to recognize the natural groups, following the indications afforded by the instincts of mankind, which led them for instance to form the class of Birds and the class of Fishes, each of which groups combines a multitude of differentiae, and is not defined by a single one as in dichotomy. The method of dichotomy is either impossible (for it would put a single group under different divisions or contrary groups under the same division), or it only furnishes a single differentia for each species…. As we said then, we must define at the outset by a multiplicity of differentiae. If we do so, privative terms will be available, which are unavailable to the dichotomist” (pp. 1001-1002, emphasis added).

This is consistent with Plato’s more general advice that classifiers, like butchers, should “cut at the joints”, i.e., look for natural distinctions rather than imposing artificial ones. Dipping back again to the negative argument, Aristotle adds:

“Now if man was nothing more than a Cleft-footed animal, this single differentia would duly represent his essence. But seeing that this is not the case, more differentiae than this one will necessarily be required to define him; and these cannot come under one division; for each single branch of a dichotomy end in a single differentia, and cannot possibly include several differentiae belonging to one and the same animal.”

“It is impossible then to reach any of the ultimate animal forms by dichotomous division” (p. 1002; see also Classification; Hermeneutic Biology?.)

Life Is Non-Boolean

George Boole (1815-1864) invented what we now call Boolean logic, which effectively assumes that all propositions are classifiable as either “true” or “false”, with no gradations of evidence or undecided cases. This provided the basis for formally defining logical operators in terms of how they transform what are called truth values, which are just the Boolean values of “true” and “false”. The use of so-called truth tables to define logical operators by cases is characteristic of what is today called “classical” logic.

Though it certainly has its uses in technical contexts, this kind of approach has been criticized as tacitly presupposing what has been called logical omniscience or the assumption of a closed world. For example, in computer science Boolean data types are used to represent things that are stipulated to have one of exactly two values. Then if we can rule out one, we can simply assume the other. This creates a closed world. “Omniscience” is implied by this kind of assumption.

The great developer of mathematical logic Gottlob Frege (1848-1925), at least at one point in his career, went so far as to argue that there are really only two distinct logical propositions: “true” and “false”. Depending one’s point of view, what I call real-world meanings are either reduced to nothing by this or are irrelevant to it.

From the point of view of “constructive” logic, on the other hand, there are infinitely many distinct propositions, distinguishable by the combination of what they presuppose and what they imply. It begins to be possible to reconstruct real-world meanings within logic instead of only outside of it.

In real life there are countless distinctions that are relevant and meaningful, and countless things that we simply don’t know. (See also Logic for People.)

Facts and Incomplete Information

A modern notion of hard-nosed common sense is to appeal exclusively to positive facts. This is also a major basis of simplistic notions of empirical science. Serious scientific methodologies are more indirect, and quite a bit more involved.

From a broadly Kantian point of view that I think Plato and Aristotle would also endorse, all putative facts are really just assertions of facts, made by people. The validity of the corresponding assertions depends on the soundness of the reasons that lead us to believe them. Thus, regardless of whether our concern is ethical or scientific, it is always the quality of reasons that matters in assessing the validity of assertions.

The notion of a fair and objective weighing of evidence for or against an assertion presupposes that we symmetrically consider the pro and con, as Plato emphasized in his discussions of “dialectic”. But the simplistic bias for positive facts results in an inherently asymmetrical treatment any time we have to deal with incomplete information, because what putative facts we currently have in our possession is in part a matter of sheer chance.

In a fact-biased approach, if there happen to be insufficient facts in our possession to adequately support a hypothesis, the hypothesis is likely to be be dismissed out of hand as “speculation”, regardless of how inherently plausible it might otherwise be. We end up assuming something is not true merely because we cannot empirically prove it is true. This is independent of any other prejudice that may also enter into situations involving human judgment.

Once again, I want to recommend a prudent suspension or qualification of belief in cases of incomplete information, rather than active disbelief. (See also Debate on Prehistory.)

Debate on Prehistory

This is a bit of a tangent from the usual topics here, but recently I’ve been dwelling on the distinctions between knowledge, well-founded belief, and not-so-well-founded belief, and I’m taking that as the point of departure. It should be no insult to science (and I certainly mean none) to suggest that empirical science aims only at what I’ve been calling well-founded belief, though received views are commonly taken for simple knowledge. The difference is that well-founded beliefs can still potentially be invalidated by new arguments or information, whereas real knowledge ought to be unconditionally valid.

I’ve been fascinated with prehistory since childhood, and in recent decades especially with the emergence of rich human cultures. Much has changed in this field during my lifetime, as relatively well-founded beliefs were replaced by better-founded ones. For example, it is now generally accepted that modern birds are surviving members of the theropod group of the dinosaur family that included raptors and T. rex, and that the extinction of the (other) dinosaurs was caused by a massive asteroid impact in the Gulf of Mexico ca. 65 million years ago.

Similarly, it is now widely accepted that biologically modern humans emerged in Africa two to three hundred thousand years ago, rather than in Europe only 40,000 years ago. Humans crossed the open sea from Southeast Asia to Australia over 50,000 years ago. If the previously known cave paintings from the late-glacial Magdalenian culture in southwest Europe were not already amazing enough testaments to the human spirit, the Chauvet cave (subject of the wonderful documentary film Cave of Forgotten Dreams by Werner Herzog) was discovered in 1994 to have equally magnificent paintings that turned out to be twice as old (from around 36,000 BP). Gobekli Tepe in Turkey has multi-ton megaliths dating from 9500 BCE, a little before the earliest evidence of agriculture in that region.

Agriculture is now believed to have independently originated in at least 11 different parts of the Old and New Worlds. Wikipedia now mentions small-scale cultivation of edible grasses by the Sea of Galilee from 21,000 BCE. Sickles apparently used for intensive harvesting of wild grains have been found in the Nile valley from at least 18,000 BCE. The Middle Eastern Natufian culture (ca. 15,000-11,500 BP) was previously thought to have had the world’s oldest agriculture, and still boasts the earliest evidence of baked bread (14,400 BP). Some Natufian portable art bears a striking stylistic resemblance to similar artifacts from Magdalenian Europe at roughly the same time. Numerous archaeologists and anthropologists have suggested that agriculture may have had a very long prehistory, beginning with deliberate efforts to promote the growth of particular wild plants that humans valued.

Currently, there is a big ongoing controversy over the cause of dramatic climate changes that occurred around 12,850 BP, at the beginning of the 1200-year period known as the Younger Dryas. The most recent ice age had begun to recede by around 20,000 BP, and the world had been getting gradually warmer. But then, suddenly, in perhaps only a single year’s time, temperatures fell by an astonishing 9 to 14 degrees centigrade. Then, in somewhere between a few years and a few decades, temperatures apparently rose again by 5 to 10 degrees centigrade. Several massive glacial lakes seem to have suddenly been emptied into the ocean, cooling it down, and there is evidence of gargantuan flooding. On a larger time scale of several thousand years including the Younger Dryas, worldwide sea levels are generally accepted to have risen around 400 feet. Many submerged archaeological sites have already been found, but this could be the tip of the proverbial iceberg.

Due to human-induced climate change, we are currently facing a sea level rise of around 50 feet from melting of the remaining ice caps, which is expected to be catastrophic. Four hundred feet dwarfs that. Today the great majority of the world’s population lives in or near coastal areas, and this may well have been true during the ice age too. Around the time of the Younger Dryas, there is evidence of intensive fishing by cultures like the Jomon of Japan — who also produced pottery older than any known from the Middle East — and the Magdalenians in Europe (not to mention many fresh-water fishing villages spread across what is now the Sahara desert).

By this time, humans would have been biologically modern for over 200,000 years, and had been at least occasionally producing magnificent art for at least 20,000 years. Stone and bone tools with amazing elegance and sophistication had been in use equally long. All hunter-gatherer cultures known to modern anthropology have complex culture, language, and spiritual beliefs. But somehow, we still have the prejudice that hunter-gatherers and “cave people” must have been extremely primitive.

The controversy I mentioned concerns evidence that like the dinosaur extinction, the Younger Dryas was caused by a cataclysm from space. Since 2007 the “Younger Dryas impact theory” has been hotly debated, but it now appears to be gaining ground. I have no particular stake in what really caused the Younger Dryas; I’m really more interested in its effects on humans. But the controversy potentially provides an interesting case study in how highly intelligent, educated people can effectively confuse apparently well-founded belief with “knowledge” that would supposedly be beyond doubt.

It also happens to be the case that Plato in the Critias gives a date for the sinking of the mythical Atlantis at around the time of the Younger Dryas. I don’t assume there is any accuracy in the details of the story — the island with the circular city and so forth — but I think archaeology already provides the basis for an extremely well-founded belief that late-glacial stone age cultures had already reached very high levels of sophistication, and that much more evidence may be hidden at as yet undiscovered underwater sites. This doesn’t mean people back then were flying around in spaceships or anything, or had magical powers, or even that they produced metal. Our standards for what represents “advanced” culture are highly distorted by our own obsessions with technology and money.

Incidentally, Plato in the Laws also casually suggests that animal and plant species come into being and pass away, as well as something like the succession of human material culture from stone to soft metals to iron. The Critias story is attributed to the Athenian lawgiver Solon, who supposedly heard it from an Egyptian priest during his travels there, but no source is given for the apparently accurate speculations about prehistory in the Laws.

All the modern fringe speculation around the Atlantis myth — and around “historical” readings of mythology in general — has given this stuff a bad name. We ought to suspend belief in things for which the evidence is shaky. But a suspension of belief need not — and should not — necessarily imply active disbelief. Our active disbeliefs ought to be well-founded up to the same standard as our active beliefs, and ought not to fall to the level of prejudice.

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).

Sellars on Kantian Imagination

The analytically trained Kantian pragmatist Wilfrid Sellars (1912-1989) is increasing recognized as one of the greatest American philosophers of the 20th century. It has been said that he played a central role in taking analytic philosophy from its empiricist beginnings to a new Kantian stage. He is known for his critique of the “Myth of the Given”, his work on material inference, and his concept of the space of reasons. I found an essay of his on the Kantian productive imagination.

He begins by contrasting two approaches to perceptual judgment. First is a standard empiricist notion that goes as far as possible in reducing judgment to grammatical predication, to the point where the perception itself is treated as a bare this, and all the cognitive work of judgment is concentrated in applying a predicate to the bare this.

“Traditionally a distinction was drawn between the visual object and the perceptual judgment about the object…. This suggested to some philosophers that to see a visual object as a brick with a red and rectangular facing surface consists in seeing the brick and believing it to be a brick with a red and rectangular facing surface: ‘This is a brick which has a red and rectangular facing surface’…. Notice that the subject term of the judgment was exhibited above as a bare demonstrative, a sheer this, and that what the object is seen as was placed in an explicitly predicate position (“The Role of Imagination in Kant’s Theory of Experience”, in In the Space of Reasons: Selected Essays of Wilfrid Sellars, Scharp and Brandom, eds., p. 455).

Rather than pretending that perception gives us only a bare this, we should recognize that at least we talking animals live always already immersed in meaningful content. The most primitive human sense perception involves taking something not just as this, but as something with definite characteristics. This will turn out to be what Kant calls a schema, as distinct from a concept.

“I submit, on the contrary, that correctly represented, a perceptual belief has the quite different form: ‘This brick with a red and rectangular facing surface’. Notice that this is not a sentence but a complex demonstrative phrase. In other words, I suggest that in such a perceptually grounded judgment as ‘This brick with a red and rectangular facing side is too large for the job at hand’ the perceptual belief proper is that tokening of a complex Mentalese demonstrative phrase which is the grammatical subject of the judgment as a whole. This can be rephrased as a distinction between a perceptual taking and what is believed about what is taken…. From this point of view, what the visual object is seen as is a matter of the content of the complex demonstrative Mentalese phrase” (ibid).

In a nonessential decoration of the argument, he mentions “Mentalese”, a term used by analytic philosophers for inner speech. We need not concern ourselves here with whether or not there is a “mental language” distinct from, but patterned on, natural language, as this term suggests. The important point is that in every human perceptual “taking”, there is a kind of linguistic or language-like articulation, which we can express with a phrase consisting of classifying terms and syntactic relations between them.

“We must add another distinction, this time between what we see and what we see of what we see…. How can a volume of white apple flesh [hidden inside the apple] be present as actuality in the visual experience if it is not seen? The answer should be obvious. It is present by virtue of being imagined (p. 457).

“Before following up this point, it should be noticed that the same is true of the red of the other side of the apple. The apple is seen as as having a red opposite side. Furthermore, the phenomenologist adds, the red of the opposite side is not merely believed in; it is bodily present in the experience. Like the white, not being seen, it is present in the experience by being imagined” (ibid).

Here he seems to recall Husserl’s perceptual “adumbrations” or foreshadowings. Sellars is a bit more straightforward and explicit in attributing these to imagination.

“Notice that to say that it is present in the experience by virtue of being imagined is not to say that it is presented as imagined…. Red may present itself as red and white present itself as white; but sensations do not present themselves as sensations, nor images as images. Otherwise philosophy would be far easier than it is” (pp. 457-458).

When we imagine something to be the case, we are most often not aware that we are doing so. We simply think or believe that it is the case. As soon as we already have experience, what Sellars in the thin modern sense calls the “actual” presence of the imagined content comes to us as primitively mixed in with that of the perceived content. It takes work to analytically separate them, and any such separation always has a hypothetical character.

“But while these [hidden] features are not seen, they are not merely believed in. These features are present in the object of perception as actualities. They are present by virtue of being imagined” (p. 458).

As with Husserl’s “presentified” contents, the contributions of imagination are not theoretical constructs, but part of the experience itself.

“We do not see of objects their causal properties, though we see them as having them…. To draw the proper consequences of this we must distinguish between imagining and imaging, just as we distinguish between perceiving and sensing…. Roughly imagining is an intimate blend of imaging and conceptualization, whereas perceiving is an intimate blend of sensing and imaging and conceptualization” (ibid).

I like the way Sellars recognizes the interweaving inherent to these “intimate blends” of imaging and conceptualization.

“Notice that the proper and common sensible features enter in both by virtue of being actual features of the image and by virtue of being items thought of or conceptualized. The applehood [by contrast] enters in only by virtue of being thought of (intentional in-existence)” (pp. 458-459).

“The upshot of the preceding section is that perceptual consciousness involves the constructing of sense-image models of external objects. This construction is the work of the imagination responding to the stimulation of the retina…. The most significant fact is that the construction is a unified process guided by a combination of sensory input on the one hand and background beliefs, memories, and expectations on the other. The complex of abilities included in this process is what Kant called the ‘productive’ as contrasted with the ‘reproductive’ imagination. The former, as we shall see, by virtue of its kinship with both sensibility and understanding unifies into one experiencing the distinctive contributions of these two faculties” (p. 459).

Here we have a very basic Kantian point about the nature of experience — all perception involves imaginative construction. Objects are not just given to us fully constituted.

“Notice once again that although the objects of which we are directly aware in perceptual consciousness are image-models, we are not aware of them as image-models. It is by phenomenological reflection (aided by what Quine calls scientific lore) that we arrive at this theoretical interpretation of perceptual consciousness…. Thus we must distinguish carefully between objects, including oneself, as conceived by the productive imagination, on the one hand and the image-models constructed by the productive imagination, on the other” (pp. 459-460).

In common with Plato, Kant is at pains to point out that everything we experience — including everything we apprehend in inner sense — is appearance. I would say we also have “contact” with reality underlying the appearances, but we do not easily get knowledge of that reality.

“Kant distinguishes between the concept of a dog and the schema of a dog…. [O]ur perceptual experience does not begin with the perception of dogs and houses…. But though the child does not yet have the conceptual framework of dogs, houses, books, etc., he does, according to Kant, have an innate conceptual framework — a proto-theory, so to speak, of spatio-temporal physical objects capable of interacting with each other; objects — and this is the crux of the matter – which are capable of generating visual inputs which vary in systematic ways with their relation to the body of the perceiver ” (p. 460).

Here he explains the important Kantian notion of a schema. Concepts express nonperspectival essences, but schemas are perspectival, involve potentially sensible content, and implicitly include a relation to a perceiver.

“Consider the example of a perceiver who sees a pyramid and is walking around it, looking at it. The concept of a red pyramid standing in various relations to a perceiver entails a family of concepts pertaining to sequences of perspectival image-models of oneself-confronting-a-pyramid. This family can be called the schema of the concept of the pyramid…. Notice that the pyramid-schema doesn’t follow from the concept of a pyramid alone. It follows from the complex concept of pyramid in such-and-such relations to a perceiver” (p. 461).

In a Kantian context, we have no access to a sensible world apart from a perceiver’s perception of it.

“However thin — as in the case of the child — the intuitive representation may be from the standpoint of the empirical concept involved, it nevertheless contains in embryo the concept of a physical object now, over there, interacting with other objects in a system which includes me. It embodies a proto-theory of a world which contains perceivers of objects in that world” (p. 465).

Here we have the basis of Kant’s “transcendental deduction”, which aims to show that perception and imagination effectively already presuppose the same categories that govern understanding. This is how Kant recovers the possibility of objectivity.

Passive Synthesis: Conclusion

Husserl’s initial discussion of associative synthesis seems to me to be the climax of his lectures on passive synthesis, resulting in a great simultaneous genesis of the experience of time, self, world, and objects. He had indicated that the next frontier would involve taking more account of the content of things as opposed to the mere genesis of their identities, but I confess I found the follow-through disappointing. Here he follows conventional treatments of association that emphasize similarity as the main basis of particular associations. In hindsight, I’m inclined to doubt whether association really ought to be the main theme governing what I just called the great simultaneous genesis.

There is a discussion of affection that I also found disappointing. Curiously, it is separated from another later section that touches on feeling. Feeling he treats only as a function of the ego, outside the scope of “passive” synthesis. I see feeling as deeply bound up with the imagination and spontaneous belief involved in preconscious synthesis. I would prefer to see the ego treated as a function of feeling, rather than vice versa.

I do think he succeeds in developing the overall notion of preconscious synthesis in a somewhat more concrete way than Kant, who already greatly fleshes out this territory in comparison with Aristotle’s brilliant but obscure hints that I take to imply a kind of synthesis at work in the “common sense” and “inner sense”. As I mentioned in the last post, the very fact that Husserl here considers subjectivity as something constituted and not only as something constituting other things is also of great importance.

I was disappointed that so much of the discussion was limited to beliefs arising out of sense perception. In his early Logical Investigations, Husserl was engaged with a much broader inquiry into meaning as something not merely subjective or psychological. At the level of what he calls passive synthesis, I would hope to see much more about the linguistic side of our being.

When Husserl was working, Sellars and Brandom had not yet developed the rediscovery of concrete meaning-based material inference. Just as much of our immersion in language is at a preconscious level, I think we make many material inferences at a preconscious level, and this provides a far richer basis for the shaping of experience than similarity-based association. (See also Phenomenological Reduction?.)

Associative Synthesis

We have reached the heart of Husserl’s passive synthesis lectures, a long subdivision on associative synthesis. This is Husserl’s re-visioning of the classic notion of association that empirical psychology ultimately derived from Locke and Hume. For Husserl, it will provide the key to the constitution of subjectivity overall.

Rather than treating association in terms of a notion of psycho-physical causality, he wants to explain it as as a product of synthesis. As Husserl now reminds us, he has been implicitly working under the phenomenological reduction, which puts “in brackets” all questions of external existence and natural causality. He focuses on what to my Aristotelian eye look like questions of form and of a kind of teleology immanent to the subject matter.

Here he again refers to Kant’s discussion of synthesis in the Critique of Pure Reason (see Capacity to Judge; Figurative Synthesis). Husserl claims that he will go further than Kant in explicitly discussing synthesis of immanent contents of consciousness, as well as apprehensions of objects of external perception. For both Husserl and Kant, all this is closely bound up with the constitution of our experience of time. Memory and expectation will again play a key role.

“[T]he path is cleared from here toward a universal theory of the genesis of a pure subjectivity, and in particular, initially in relation to its lower level of pure passivity. Phenomenological eidetic [form-oriented] analyses of consciousness constituting a temporal objectlike formation already led to the beginnings of a lawful regularity of genesis prevailing in subjective life. We see very quickly that the phenomenology of association is, so to speak, a higher continuation of the doctrine of original time-constitution. Through association, the constitutive accomplishment is extended to all levels of apperception” (Analyses Concerning Passive and Active Synthesis, p. 163).

“The doctrine of the genesis of reproductions and of their formations is the doctrine of association in the first and more genuine sense. But inseparably connected to this, or rather, grounded upon this is a higher level of association and doctrine of association, namely, a doctrine of the genesis of expectations, and closely related to it, the genesis of apperceptions to which belong the horizons of actual and possible expectations. All in all, it concerns the genesis of the phenomena of expectation, that is, of those specific intentions that are anticipatory” (p. 164).

Association, as Husserl analyzes it, is constituted from memories of things similar to the present object. In turn, it is from particular associations that particular expectations are constituted. Now we see memory and expectation linked together in a larger process that is precisely one of association.

“But it is precisely the analysis of associative phenomena that draws our attention to the fact that consciousness must not necessarily be a consciousness of a single object for itself, and accordingly, we touch on a new problem here: how a consciousness of something particular and how a consciousness of explicit particulars becomes possible as a consciousness of a multiplicity and a consciousness of wholeness; namely, a comparative analysis also shows the opposing possibility of many [elements], indeed, a multiplicity being continually fused into a unity within one consciousness, [implicitly], such that consciousness is not a consciousness of a multiplicity, a consciousness that becomes aware of separated particulars in a unitary and yet separate manner” (p. 165).

Here he is leading up to the central role of the experience of time, simultaneity, and streaming in the constitution of subjectivity and in turn of external experience, already foreshadowed above.

“We realize, then, that it really concerns nothing else than clarifying the fundamental problem, the basic, essential conditions of the possibility of a subjectivity itself. What must belong to it so that a subjectivity can have the essential sense without which it could not be subjectivity, [namely,] the sense of an existing subjectivity being for itself, and precisely thereby of a subjectivity constituting itself as being for itself? Certainly, a complete phenomenology of reproductive awakening concerns and exhausts this problem only with respect to the one side, namely, with respect to the constitution of one’s past, or rather, the constitution of the self-having-been in endless immanent time. But we will see that the supplementary part, the other half of the problem, is the realm of the phenomenology of inductive, anticipatory association. Here we will make clear the essential conditions of the possibility of a subjectivity that can know itself as identically one, having its inherent endless future life” (p. 169).

“Awakening” seems to be Husserl’s preferred term for the activation of memory that is somehow relevant to what is present. This may relate to a distinction I have found obscure so far, between memory as “empty” intention and “intuitive” memory. My difficulty has been that no memory, insofar as it is of the past, concerns a present object, so it seems to me as though all memory then would be what he calls empty intention. But perhaps the “intuitive” memory is a memory of a past object insofar as it is related to an intuited present object.

“Clearly, what is presupposed is the synthesis that is continually accomplished in original time-consciousness. In the concretely full, streaming living present we have present, past, and future life already united in a certain mode of givenness. But this manner in which subjectivity becomes conscious of its past and future life along with its inherent intentional contents is an incomplete one. The aforementioned manner would be meaningless for the ego if there were no awakening, for the retentions are empty and even sink into the undifferentiated retentional background. Our consciousness of the protentional future is especially empty. On the other hand, there would be no progress at all without this beginning. In the ABCs of the constitution of all objectivity given to consciousness and of subjectivity as existing for itself, here is the ‘A’. It consists, we might say, in a universal, formal framework, in a synthetically constituted form in which all other possible syntheses must participate.”

As in Kant, the experience of time for Husserl is a synthetic construct that anchors things like identities of objects, as well as the overall shape of consciousness.

“Still many other types of syntheses are transcendental in the special sense, as apodictically [demonstrably] necessary for the genesis of a subjectivity (which is indeed only conceivable in genesis). As we said, these syntheses run their course together with the synthesis constituting the temporal form of all objects, and thus must co-relate to the temporal content, the temporally formed content of the object” (pp. 170-171).

“Since the spatial world is constituted through consciousness, since it can only be there for us as existing and can only be conceived at all by virtue of certain syntheses carried out in immanence, it is clear that the constitutive problems of the world presuppose the doctrine of the necessary, most general structures and the synthetic shapes of immanence that are possible in general” (p. 171).

Working under the phenomenological reduction, he is not concerned with the transcendent existence of external objects, but only with the more particular ways in which they are immanently determined or determinable as meanings for us.

“What is constituted universally through these syntheses is known under the rubric of coexistence and succession of all immanent objects in relation to one another” (p. 172).

The universality here has to do with the generality of the form of the experience of the flow of time.

“Accordingly, corresponding to every Now is a universal synthesis. Through this synthesis, a universal concrete present is constituted, a present into which all particulars that are set off from one another are integrated. Further, the fact that the Now streams in and through temporal orientations implies at the same time another universal synthesis in constituting life whereby we are conscious of the presents coursing as a sequential unity” (p. 173).

The integral Now and the streaming sequence of Nows are in effect the outermost frames in which all concrete experience is constituted as coherent.

“This is the most general and the most primary synthesis that necessarily connects all particular objects of which we become conscious…. But naturally, the synthesis of time-consciousness also contains (and already as a presupposition for possible coexistences and succession) that synthesis in which one object is constituted as identically one or (what amounts to the same thing) as enduringly one in streaming manifolds…. [T]ime-consciousness is the primordial place of the constitution of the unity of identity or of an objectlike formation, and then of the forms of connection of coexistence and succession of all objectlike formations” (ibid).

“But what gives unity to the particular object with respect to content, what makes up the differences between each of them with respect to content…, what makes division possible and the relation between parts in consciousness, and so forth — the analysis of time alone cannot tell us, for it abstracts precisely from content. Thus, it does not give us any idea of the necessary synthetic structures of the steaming present and of the unitary stream of the presents — which in some way concerns the particularity of content” (p. 174).

The implicit distinction between the constitution of identities of objects in the quotation before last, on the one hand, and that of their unities with respect to content in the quotation immediately above, on the other, is not yet clear to me. It makes sense that the general forms of time, coexistence, and succession do not tell us the whole story about particular concrete objects. I do not see, however, how it would be possible to constitute the identities of concrete objects — in Aristotelian terms, their surface status as “substances” in the sense of things persisting through change — without taking into account their content, or their deeper substantiality in the sense of “what it was to have been” the things in question. I expect that he will have more to say about the content in what follows, so hopefully this will be clarified.

The very idea of treating subjectivity as something constituted opens up a huge new territory that later authors like Foucault, Ricoeur, and de Libera have substantially developed, and in which I have been tremendously interested. The works that Husserl published in his lifetime seemed to me mainly to focus on the constitution of objects by a subjectivity that was somewhat taken for granted. That Husserl in fact went beyond this is important to recognize.

Next in this series: Passive Synthesis: Conclusion

Intention and Intuition

Husserl continues his passive synthesis lectures with more discussion of intuition as a confirmation of the concordance of intentions. It now seems pretty clear that intuition for Husserl is all about the “presentness” of presentations, and unlike the common usage does not involve any leaps. He distinguishes between intuitions that are “self-giving” (principally, external perceptions), and those that are not self-giving, but instead involve a “presentification”, like memories and expectations. He discusses at some length the question whether it is possible in advance to know which of our general intentions and presentations can potentially be confirmed in intuition.

He speaks of intentions “wanting” and “striving” to be fulfilled in present intuition, but contrasts this with a wish or will. Instead, it seems to be a more elemental directedness toward filling in the metaphorical hole in what he calls the “empty” intentions that are not correlated to a present object in intuition from external perception. Preconscious beliefs about an external object are subject to a kind of preconscious corroboration by comparison to direct impressions from sense perception.

I like the quasi-personification of intentions and intuitions here, as “wanting” or “giving themselves” (see Ideas Are Not Inert). Plato in the Republic compared the soul to a city or community of thoughts, feelings, and perceptions, thus suggesting that the kind of unity the soul has is comparable to the kind of unity a concrete community has. All our thoughts, feelings, and perceptions thus need not be attributed monolithically to a single, central agent; rather, our agency as individuals is the combined effect of numerous specialized, more or less cooperating but somewhat decentralized agencies.

All our intentions “want” to coalesce into the unity of a world.

“That we have a consciousness of our own life as a life endlessly streaming along; that we continually have an experiencing consciousness in this life, but in connection to this in the widest parameters, an emptily presenting consciousness of an environing-world — this is the accomplishment of unity out of manifold, multifariously changing intentions, intuitive and non-intuitive intentions that are nonetheless concordant with one another: intentions that in their particularity coalesce to form concrete syntheses again and again. But these complex syntheses cannot remain isolated. All particular syntheses, through which things in perception, in memory, etc., are given, are surrounded by a general milieu of empty intentions being ever newly awakened; and they do not float there in an isolated manner, but rather, are themselves synthetically intertwined with one another. For us the universal synthesis of harmonizing intentional syntheses corresponds to ‘the’ world, and belonging to it is a universal belief-certainty.”

“Yet as we already mentioned, there are breaks here and there, discordances; many a partial belief is crossed out and becomes a disbelief, many a doubt arises and remains unsolved for a time, and so forth. But ultimately, proper to every disbelief is a positive belief of a new materially relevant sense, to every doubt a materially relevant solution; and now if the world gets an altered sense through many particular changes, there is a unity of synthesis in spite of such alterations running through the successive sequence of universal intendings of a world — it is one and the same world, an enduring world, only, as we say, corrected in its particular details, which is to say, freed from ‘false apprehensions’; it is in itself the same world. All of this seems very simple, and yet it is full of marvelous enigmas and gives rise to profound considerations” (Analyses Concerning Passive and Active Synthesis, pp. 145-146).

Next in this series: Associative Synthesis

Intuition, Presentation, Time

The first part of the detailed discussion of “evidence” in Husserl’s passive synthesis lectures expands on his previous remarks about the interrelations between present intuitions and “presentifications” of what he calls “empty” intentions, which seem to be those pertaining to things that are non-present, but somehow relevant to what is present. It somewhat clarifies what he means by intuition; begins to develop important ideas about the role of time in the synthesis of experience that have some analogy to similar themes in Kant; and introduces Husserl’s reinterpretation of association, which will probably turn out to be the centerpiece of these lectures overall.

There seems to be a two-sided character to Husserl’s development here. On the one hand, he starts with a strong bias in favor of presence and immediacy. On the other, he quickly and repeatedly points out that every present intuition “points beyond its own content” by means of a related horizon of “empty” intentions of contents that are not directly present, but are implied in or by what is directly present. It is this latter aspect that I find especially interesting.

Another term he uses, which seems to subsume both present intuitions and “presentifications”, is “presentation”. Husserl says “Thus there are intuitive presentations of something present that are surely not perceptions of that present something” (Analyses Concerning Passive and Active Synthesis, p. 110), and these are the presentifications of empty intentions, as in memory and expectation. The suggestion seems to be that no presentation is self-sufficient; as was said above about present intuitions, every presentation also intrinsically points beyond itself. This I would wholeheartedly endorse.

I note here that Husserl says we have intuitive presentifications of memories and expectations that are not themselves present intuitions. I think the idea is that these are synthetically joined together with present intuitions that point to them, and this is what explains the “intuitive but not intuition” status he attributes to them. So far at least, I am not aware that Kant ever spoke of concrete memories or expectations as “intuitive”. Kant did say that general intuitions of space and time are presupposed by our intuitions of the sensible manifold.

Does Husserl think we have intuitions of objects? Does Kant? I think that in both cases, positive answers involve equivocation on what an “object” is. We saw that Husserl speaks of loosely of “objects given to consciousness” by the senses, and refers to an object “in the flesh” that we always have, before quickly pointing out that what we definitely have in the flesh is highly indeterminate. Similarly, I see commentators on Kant sometimes referring to objects being “given” in intuition, but only in an indeterminate way.

It has been pointed out that German has two words that get translated as “object”: the cognate Objekt, and Gegenstand, which literally means “something standing against”. The “standing against” one seems well suited to the indeterminate case, and this would be helpful in resolving this kind of ambiguity about objects.

I think that at least in the context of Kant, it would be wrong to say that intuition gives us proper objects, because I don’t think we have a proper object in Kant until a concept (a universal) is applied. What Kantian intuition gives us is a raw manifold of particulars that can potentially be discriminated into proper objects once concepts are applied.

Husserl says, “[W]hat is past extends unaltered into the future in the manner of an object for consciousness. This future proceeds from the reproduced past and does so in such a way that this future is at the same time co-present, relative to our current perceptual present to which these things here in our current perceptual field belong…. Obviously, expectations are not always like this, merely extending the perceptual moment continuously into the future. Something unknown, something singular never yet experienced can also be fore-seen, like an event that is indeed expected, but yet is singularly new” (p. 111).

“The problem of evidence led us back to the distinctive syntheses of coinciding that forms identities, namely to such syntheses in which intuitions and empty presentations (or intuitions and intuitions) are synthetically united, but whereby empty presentations and their fulfillment once again play an essential role” (ibid).

Here we have the vital point that identities of things are not given to us; as we experience them, they are results of passive synthesis.

“[T]he primary task becomes elucidating the founding level of the passive syntheses of ‘verification’ lying at the basis of all active verification. To do this, however, one must gain deeper insights into the structures of the intuitions and empty presentations that may be functional here…. We will be led to insights into the most universal lawful regularities of essences, to the most universal lawful regularities of structure concerning the unity of transcendental inner life, but also to the most universal lawful regularities of genesis” (p. 112).

“In all of this we find internal structural intertwinings…. Only when we understand them in their structural interrelatedness can we also understand how they function in synthetic interrelatedness, including here, as well, how they can function as confirming or confirmed” (pp. 112-113).

Again, every presentation points beyond itself.

“[I]n the synthesis, we gain an evidence-consciousness, a consciousness that exactly the same [object] that was meant in an empty manner is there in intuition in a genuine way, as the same [object] actually presented…. This is certainly the first aspect of the fundamental lawfulness of the constitution of original time-consciousness: that every lived-experience, speaking most basically, every Now-phase that arises in a primordially impressional manner is continually modified in retention” (p. 114, brackets in original).

Now we have explicit mention of the “constitution of original time-consciousness”. This was an extraordinary idea of Kant that Husserl took up, that our experience of time itself is not something given to us, but is the product of a passive synthesis.

“In our analysis of perception, which was in this regard an analysis of the temporal modes of givenness, we have already touched upon the essentially new role of protentions over against the role of retentions. The rubric, protention, designates the second aspect of genetic primordial lawfulness that strictly governs the life of consciousness as the time-constituting unitary stream” (p. 115).

“In spite of its pure passivity, we spoke of protention as an expectation, with the colorful image of the present meeting the future with open arms. Accordingly, we already speak this way in pure passivity, which is to say, even prior to [actively] grasping and viewing the perceptual object. We did not use such expressions, and we could not use such expressions with respect to retention. In this connection, there is a difference in the way protention and retention function in mindful perception, when we take note [of something] and grasp it. We are mindfully directed, purely and simply, toward the present object, toward the ever new Now that emerges as fulfilling the expectation; and in and through it, it is directed further toward the approaching object. Mindful perceiving follows the protentional continuity. The directedness-ahead, which already lies in passive perception itself, becomes patent in mindful perceiving. On the other hand, there is however not a directedness in the retentional continuity; there is not a directedness that would follow the trail of pasts being pushed back further and further” (p. 116).

This assymmetry between protention and retention tracks with the distinction that we experience time as moving continuously forward, but never backward.

“In order to clarify all this it will do us well initially to go beyond protentions as intentions of expectation, and to draw upon other empty presentations that are structurally related to them, and that are at the same time different from all mere retentions. We have in mind making co-present, memories of the present as forms of intuitive presentations, alongside memories of the past and memories of the future” (pp. 116-117).

He doesn’t explain the reference to “memories of the future”. I can only suppose that what is meant is something like a reproduction of an expectation.

“If we now consider the genetically more original modes of making co-present, then at issue, e.g., for every perceptual object, are its entire horizons that are constitutive of it, horizons that belong immediately to it…. We recognize this peculiar feature with respect to all such presentations: that they exist with other presentations in a synthetic nexus of a special kind, namely, in a synthetic nexus that lies entirely outside of the genre of identifying syntheses or syntheses of coinciding” (p. 117).

He speaks of horizons and pointings-beyond as constitituting the object. They are not some sort of optional decorations that we could choose to ignore, and still have the object. This is vitally important.

“If, from the very beginning, we remain focused most simply on the realm that already has our exclusive interest now, the realm of passive presentations as the material for passively emerging syntheses, then we will be concerned generally speaking with such syntheses in which a presentation points beyond itself to another presentation. The latter gains a new inner character that it otherwise could not have. It is the character of the specific ‘intention’, that is, of teleological directedness, of being-intended, of meantness” (p. 118).

Here we have a genesis in passive synthesis of the famous Husserlian intentionality.

“For want of terms at our disposal, we will avail ourselves of the apposition, ‘passive’, passive intention. And from here on we will speak only of passively intending presentations. At the outset we also want to name the synthesis in which this intention arises: associative synthesis” (pp. 118-119).

I am not greatly enamored of this use of “passive” for something that is really only relatively more passive than something else, but for this exposition I’ll continue following Husserl and use it. I prefer “preconscious”.

We’ll hear much more about the associative synthesis associated with directedness and intentionality later on. For now, it’s worth remarking that its very characterization as a form of synthesis separates it from the more common psycho-physical causal notion of association.

“Indeed, even retentions, those emerging originally, synthetically cohere with one another and with the primordial impression, but this synthesis proper to original time-consciousness is not a synthesis of association; retentions do not arise through an associative awakening directed backward from the impression, and thus, they do not have in themselves a directedness radiating out from there toward the emptily presented past” (p. 119).

Here we have a sharp distinction between the synthesis responsible for our experience of the flow of time and the associative synthesis that generates intentionality.

“I said that retentions, as they arise in their originality, have no intentional character. This does not rule out that in certain circumstances and in their own way they can assume this intentional character later…. Now, how does a retention get this oriented structure? By a subsequent association, of course” (p. 120).
