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).

Husserl on Passive Synthesis

Volume IX of Edmund Husserl’s collected works is entitled in English Analyses Concerning Passive and Active Synthesis. It consists of lectures given between 1920 and 1926, supplemented with various contemporary unpublished notes and manuscripts. Husserl explicitly offers his notion of passive synthesis as a successor to Kant’s idea of a productive synthesis of imagination (see Capacity to Judge; Figurative Synthesis). As usual when I read Husserl, in spite of reservations that some more global concepts he uses seem “too strong”, I am reveling in the richness and originality of his detailed developments.

The term “passive synthesis” has an air of paradox about it, but I have been very interested in the way both Aristotle and Kant deal with aspects of human sentience and sapience that are neither entirely active nor entirely passive, and this is the real significance of this whole topic. In a more general context, Hegel and Paul Ricoeur (who was an acute reader of Husserl) both also have much of value to say about such mixed forms. I tend to think that nothing in the human sphere is ever entirely active or entirely passive.

In spite of Husserl’s pains to distinguish what he called “transcendental” subjectivity (in a sense somewhat different from, but related to, that of Kant) from “psychological” subjectivity — and his early sharp criticism of “psychologism” — translator Anthony Steinbock’s introduction points out that during the less known stage documented in this volume, when Husserl began speaking of a “genetic” phenomenology, he also wrote extensively in the area of philosophical psychology. The material on passive synthesis could be considered a prime instance of this.

For Husserl, all philosophy — and indeed all science, if it is really doing what he thinks it should — ought to make us wiser and better.

He begins with some leading points from what he calls transcendental logic. With extremely broad brush, this is concerned with neither formalization nor real-world inference, but rather focuses on the constitution of meanings.

The main section on passive synthesis begins by noting some aspects of perception that are commonly passed over, including “perspectival adumbration of spatial objects”; “fullness and emptiness in the perceptual process”; how our acquired knowledge can be freely at our disposal; and the relation between being and being perceived.

Next he develops an unusually broad notion of modality, as a kind of modification of the sense of contents. This includes negation, but Husserl is not concerned here with ordinary logical negation. Under negation he discusses things like “disappointment as an occurrence that runs counter to the synthesis of fulfillment”; “partial fulfillment”; and “retroactive crossing out in the retentional sphere and transformation of the previous perceptual sense”. Then he treats doubt, including its origin in conflicting apprehensions and its resolution. Next comes the more standard modality of possibility, which he transforms by dividing it into “open” possibilities and “enticing” possibilities that motivate us. He concludes this subdivision by discussing relations between passive and active modalization, including “position-taking of the ego as the active response to the modal modification of passive doxa [belief]” and “questioning as a multilayered striving toward overcoming modalization through a judicative decision”.

The following subdivision is concerned with the notion of evidence. Here he discusses the “structure of fulfillment” as a “synthesis of empty presentation”; then “passive and active intentions and the forms of their confirmation and verification”, including “picturing, clarifying, and confirmation in the syntheses of bringing to intuition”, “possible types of intuition”, and “possible types of empty presentation”; “intention toward fulfillment [as] the intention toward self-giving”; “epistemic striving and striving toward the effective realization of the presented object”; and “the different relationships of intention and the intended self”. This subdivision concludes with “the problem of definitiveness in experience”, including “the problematic character of a verification that is possible for all intentions and its consequence for belief in experience”; “development of the problem of the in-itself for the immanent sphere”; and “rememberings as the source for an in-itself of objects”.

A long subdivision is devoted to association. Here he will be concerned with motivational relations rather than the psycho-physical causal relations with which “association” is associated in the empiricist tradition. A partial list of the contents includes “presuppositions of associative synthesis”; “syntheses of original time-consciousness”; “syntheses of homogeneity in the unity of a streaming present”‘; “the phenomenon of contrast”; “individuation in succession and coexistence”; “affection as effecting an allure on the ego”; “the gradation of affection in the living present and in the retentional process”; “the function of awakening in the living present”; “retroactive awakening of the empty presentations in the distant sphere”; “the transition of awakened empty presentations in rememberings”; “the difference between continuous and discontinuous awakening”; and “the phenomenon of expectation”.

The final subdivision of the section on passive synthesis is devoted to the stream of consciousness. This includes “illusion in the realm of remembering”; “overlapping, fusion, and conflict of rememberings of different pasts”; “the true being of the system of the immanent past”; “confirmation of self-givenness by expanding into the outer horizon”; “the primordial transcendence of the past of consciousness and the idea of its complete self-giving”; “the problem of a true being for the future of consciousness”; “disappointment as an essential moment of expectation”; and “the constitution of the objective world in its significance for the determinate prefiguring of futural consciousness”.

This is followed by a section on active synthesis, which also treats of “a transcendental, genetic logic”. Voluminous appendices further expand on the topics treated. (See Husserl on Perception; Crossing Out; Enticing Possibilities?; Active and Passive; Husserl on Evidence: Introduction; Intuition, Presentation, Time; Intention and Intuition; Associative Synthesis; Passive Synthesis: Conclusion.)

Figurative Synthesis

I wanted to extract a few more key points from Beatrice Longuenesse’s landmark study Kant and the Capacity to Judge. She strongly emphasizes that judgment for Kant refers to a complex activity, not a simple reaching of conclusions. She especially stresses the role of a capacity to judge that precedes any particular judgment and is grounded in a synthesis of imagination. (See Capacity to Judge; Imagination: Aristotle, Kant; Kantian Synthesis.)

At issue here is the very capacity for discursive thought, as well as “the manner in which things are given to us” (p. 225, emphasis in original), which for Kant involves what he called intuition. (See also Beauty and Discursivity).

Through careful textual analysis, Longuenesse argues that Kant’s claim to derive logical categories from forms of judgment makes far more sense than most previous commentators had recognized. For Kant, she argues, the “forms of judgment” are not just logical abstractions but essential cognitive acts that reflect “universal rules of discursive thought” (p. 5).

She recalls Kant’s insistence that the early modern tradition was wrong to take categorical judgments (simple predications like “A is B“) as the model for judgments in general. For Kant, hypothetical and disjunctive judgments (“if A then B” and “not both A and B“, respectively) are more primitive. These correspond to the judgments of material consequence and material incompatibility that Brandom argues form the basis of real-world reasoning.

Another distinctive Kantian thesis is that space and time are neither objective realities nor discursive concepts that we apply. Rather, they are intuitions and necessary forms of all sensibility. Kantian intuitions are produced by the synthesis of imagination according to definite rules.

“[I]ntuition is a species of cognition (Erkenntnis), that is, a conscious representation related to an object. As such it is distinguished from mere sensation, which is a mere state of the subject, by itself unrelated to any object…. One might say that, in intuition, the object is represented even if it is not recognized (under a concept).” (pp. 219-220, emphasis in original).

Before we apply any concepts or judgments, “Representational receptivity, the capacity to process affections into sensations (conscious representations), must also be able to present these sensations in an intuition of space and an intuition of time. This occurs when the affection from outside is the occasion for the affection from inside — the figurative synthesis. The form of the receptive capacity is thus a merely potential form, a form that is actualized only by the figurative synthesis” (p. 221, emphasis in original).

“[A]ccording to Locke, in this receptivity to its own acts the mind mirrors itself, just as in sensation it mirrors outer objects…. Kant shares with Locke the conception of inner sense as receptivity, but he no longer considers the mind as a mirror, either in relation to itself or in relation to objects…. Just as the thing in itself that affects me from outside is forever unknowable to me, I who affect myself from within by my own representative act am forever unknowable to me” (p. 239, emphasis added).

The point that the mind is not a mirror — either of itself or of the world — is extremely important. The mirror analogy Kant is rejecting is a product of early modern representationalism. We can still have well-founded beliefs about things of which we have no knowledge in a strict sense.

“Kant’s explanation is roughly this: our receptivity is constituted in such a way that objects are intuited as outer objects only in the form of space. But the form of space is itself intuited only insofar as an act, by which the ‘manifold of a given cognition is brought to the objective unity of apperception’, affects inner sense. Thanks to this act the manifold becomes consciously perceived, and this occurs only in the form of time” (p. 240, emphasis in original).

She develops Kant’s idea that mathematics is grounded in this kind of intuition, ultimately derived from the conditions governing imaginative synthesis. In particular, for Kant our apprehensions of unities and any kind of identification of units are consequences of imaginative synthesis.

“Extension and figure belong to the ‘pure intuition’ of space, which is ‘that in which the manifold of appearances can be ordered’, that is, that by limitation of which the extension and figure of a given object are delineated. Therefore, space and time provide the form of appearances only insofar as they are themselves an intuition: a pure intuition, that is, an intuition preceding and conditioning all empirical intuition; and an undivided intuition, that is, an intuition that is presupposed by other intuitions rather than resulting from their combinations” (p. 219, emphasis in original).

“According to Locke, the idea of unity naturally accompanies every object of our senses, and the idea of number arises from repeating the idea of unity and associating a sign with each collection thus generated by addition of units…. But for Kant, the idea (the concept) of a unit is not given with each sensory object. It presupposes an act of constituting a homogeneous multiplicity…. Thus the idea of number is not the idea of a collection of given units to which we associate a sign, but the reflected representation of a rule for synthesis, that is, for the act of constituting a homogeneous multiplicity. When such an act is presented a priori in intuition, a concept of number is constructed.” (p. 260, emphasis in original).

“Mathematics has no principles in the absolute sense required by reason. Axioms are not universal propositions cognized by means of pure concepts. They may be universally and apodeictically true, but their truth is based on the pure intuition of space, not derived from pure concepts according to the principle of contradiction” (p. 287).

Incidentally, Longuenesse thinks it does not follow from Kant’s account that space is necessarily Euclidean, as many commentators have believed and Kant himself suggested.

Thickness of Experience

Experience is not just a razor-thin interaction between us and the world, balanced on the moving point of “now”. It is made richer by two complicating dimensions — one of cumulative effects across time that are superimposed at each moment (as when we say someone is “experienced”), and one of a vast network of simultaneous relations at work in shaping each single moment.

Very Different Kinds of “Will”

Two radically different things are both called “will”. One is a definite orientation and effort toward this end rather than that, analogous to a kind of desire. The other is supposed to be a power of decision independent of deliberation.

I don’t believe that there is or could be such a thing as decision with absolutely no deliberation. What we have is an ability to deliberate, and to choose between alternatives based on that deliberation (see also What We Really Want). Neither deliberation nor decision could apply to an eternal being, because these necessarily involve time and change.

Something from Nothing?

The idea of something from nothing always seemed to me like pulling rabbits out of a hat. Taken in a piecemeal sense, it would seem to be completely arbitrary, and arbitrariness leads to all sorts of bad things. Nothing good is arbitrary.

Leibniz defended creation from nothing and particular providence, while insisting that God does not intervene arbitrarily in the world. Already Augustine had said that what are called miracles are only exceptions to the usual course of nature, and that God never contravenes nature in an absolute sense. This leaves room for debate as to what kinds of exceptions can occur.

If God is the pure To-Be that gives being to beings as Aquinas says, creation from nothing would seem to mean only that the giving of being is not a case of “making from”. But why is this not just called Being giving being? What does “nothing” have to do with it? Of course, the doctrine of creation from nothing long predates Aquinas, and Aquinas was a consummate diplomat in matters of doctrine. Common doctrine is not a simple matter of truth, as the dogmatists would have it; it is a kind of social compromise that helps keep the peace. Preserving accepted phrases while giving them new meaning is a time-honored diplomatic move.

Aquinas’ notion of creation was likely also in part developed to oppose the dualist teachings of the Cathars, according to whom the physical world was created by an evil power.

I have considerable sympathy for the eternity of the world, or alternatively some sort of eternal creation, such as Aquinas recognized to be logically possible. More sophisticated accounts of creation like those of Augustine and Aquinas explicitly include the creation of time, so that there would be no “time before creation”, even though they affirm a beginning. I have trouble distinguishing a beginning outside of time from eternity.

Form vs Action

Lately I’ve been assembling materials for a contrast between two different “root metaphors” that have been used in making sense of life, the world, and things — one a notion of form associated especially with Aristotle, and the other a Latin scholastic and modern notion of action. This is also related to the historical transformation of the notion of efficient cause and of causality in general.

The first thing to note is that these are families of metaphors rather than uniform applications of the “same” two concepts. Literal shapes, linguistic meanings, and patterns of activity are all called “forms”, but do not reflect the same concept. The “action” of creation from nothing and that of mechanical impulse are two entirely different concepts.

The unifying themes, I think, are that “action” is supposed to be something more or less simple, immediate, and instantaneous, supporting what is supposed to be a kind of bottom-up, foundational explanation of things, whereas “form” always involves some “intensional” complexity and mediation; may involve extension in time and space that further ramifies that intensional complexity and mediation; and supports a kind of “middle-out” explanation that begins with reflection on middle-sized elements of actual experience, rather than a posited foundation of ultimate simple constituents.

(For some additional complications regarding the above simple picture of action, see A Thomistic Grammar of Action.)

Questioning the Role of Action

Which comes first in the order of explanation: action, as immediate doing; or patterns of activity or practice, as extended, intricately developed over time, mediated, purposeful, and responsive to circumstance? I think it is more the latter.

What I aim to question here is not at all the reality of change or activity, but rather what might be called the “action model” — a way of explaining extended processes and changes and human reality in general in terms of punctual and immediate actions or events. The question is, do we focus on understanding larger processes and developments as the sum of discrete actions, or do we focus on understanding more or less immediate actions in terms of their place in larger processes and developments?

There is more than just a simple polarity here — meaning consists of both concrete detail and a larger context, and we need each of these to help elaborate the other. Nonetheless I want to suggest that it is better to explain things from the larger perspective of activities rather than the narrower one of actions.

Activity, Embodiment, Essence

I think any finite activity requires some sort of embodiment, and consequently that anything like the practically engaged spirits Berkeley talks about must also have some embodiment. On the other hand, the various strands of activity from which our eventual essence is precipitated over time — commitments, thoughts, feelings — are not strictly tied to single individuals, but are capable of being shared or spread between individuals.

Most notably, this often happens with parents and their children, but it also applies whenever someone significantly influences the commitments, thoughts, and feelings of someone else. I feel very strongly that I partially embody the essence and characters of both my late parents — who they were as human beings — and I see the same in my two sisters. Aristotle suggests that this concrete transference of embodied essence from parents to children is a kind of immortality that goes beyond the eternal virtual persistence of our essence itself.

Our commitments, thoughts, and feelings are not mere accidents, but rather comprise the activity that constitutes our essence. I put commitments first, because they are the least ephemeral. In mentioning commitments I mean above all the real, effective, enduring commitments embodied in what we do and how we act.

Time and Eternity

One of Kant’s innovations was a new analysis of the constitution of temporal experience. His famous theses about the role of synthesis in experience provide new insight into the paradoxes of temporal being or “becoming”, and its relation or non-relation to something outside of time. These had been raised by pre-Socratics like Heraclitus and Zeno of Elea, and more satisfactorily treated by Plato and Aristotle.

Heraclitus famously said that everything flows, you can’t step into the same river twice, and things change into their opposites. Zeno went in the opposite direction, conceiving space and time in terms of instants and points, neither of which have any magnitude. He then pointed out that motion at a durationless instant is a logical contradiction. On this basis, Zeno claimed to prove various things that violate common sense, such as that an arrow can’t fly, and that the speedy Achilles could never catch up with a turtle that had a head start. From this he concluded that motion, space, and time were mere illusions.

Plato seems to have at first focused on a sharp distinction between true “being” as eternal on the one hand, and becoming in time as mere appearance on the other. This distinction allowed him to have it both ways. But in dialogues that are thought to have been written later such as Theaetetus and The Sophist, he came to suggest that being and time are not simply two disjunct categories.

Aristotle made time and space more intelligible by developing notions of duration and extension. For Aristotle, duration and extension come first, while durationless instants, magnitudeless points, and pure flux are all abstractions. I see him as an early advocate of the primacy of process. For Aristotle, the key to making this viable is to be able to explain how becoming as we experience it is really not just a pure flux, but rather is full of islands of relative stability that allow us — contrary to Heraclitus — to reidentify objects as having an underlying basis of sameness that persists through various kinds of change. It turns out that the edges of the islands are not rigidly distinct, but he developed the notion conventionally translated as “substance” to explain our experience of the relatively persistent form of their middles.

It is here that Kant’s contribution is significant. Aristotle develops a plausible account of the persistence of form through change, but he discusses it mainly from the point of view of how things are, even though he separately suggests that experience is also shaped by processes of interpretation by us. Kant took up that suggestion, and developed it in considerable detail. Kant consistently emphasizes our role in constituting the stability of form of things we experience in time, though he also insists on an “empirical realism” that justifies most of what we get from so-called common sense. This implies that for Kant as well, there implicitly must be some basis in the way things are, for the stable constructs we come up with. Much of Hegel’s Phenomenology was devoted to a further development of these Kantian insights.

The neoplatonists and Augustine insisted that things in time have a source and destination in eternity. Classic neoplatonism attempted to treat this relation as a sort of quasi-logical unfolding of the divine essence, while Augustine identified it with the act of creation. The relation of temporal being to eternity remained a notorious point of difficulty in neoplatonism, while Augustine called it a mystery.

Hegel thought that Augustine ended up locating all reality in the Eternal, and that this resulted in a devaluation of actual life and experience. Aquinas already used ideas from Aristotle to allow for a more positive evaluation of temporal being. Some spiritual traditions go further and suggest that we humans have a sort of co-creator role in the world we experience. But it was Kant who mainly developed the basis for a non-supernatural explanation consonant with the spirit of this. The main point is that the world is not initially given in the form of pre-existing objects. We separate out objects from the sensible continuum, but at the same time this is not an arbitrary operation. We can’t just materialize a unicorn by thinking of one, but we do play a major active role in the construction of universals like “horse”, and in the recognition of persistent individuals.

Essences of things, once constituted, seem to “subsist” in some virtual way outside of time. The traditional view was that essences are straightforwardly built into the nature of things, or else simply dictated by God. Either way, this means that for us, they would be pre-given. I don’t think Aristotle really regards them this way, but only in the special case of biological organisms does he investigate their genealogy. Kant on the other hand effectively develops a generalized genealogy of essences, showing how they can be understood as temporally constituted.

Another of Kant’s big innovations is in explaining how we play a significant role in our own constitution. I think it is a grievous error to regard such processes of self-constitution as beginning with a blank slate, or as magically independent of real-world constraints, but there is a very important way in which we end up defining who we are — not by an explicit decision, but indirectly through the sum total of our commitments, actions, and responses to things.

That ethical “who we are”, while originating in time, is itself an essence with virtual subsistence. As with all essences, considered in its virtual subsistence, it is eternal. Aristotle would say that our essence stops evolving when our temporal being comes to an end. At that point, who we were is finally stabilized, as the total act of a life.
