Tag: Discursive Reasoning

Nature, Ends, Normativity

From an Aristotelian point of view, the works of nature result from an ordering of ends. In modern terms, nature for Aristotle is not “value free”, and I take this to be a good thing. But from a strict Kantian point of view, we are the bearers of value, and the attribution of ends to nature independent of us is only a kind of beneficial heuristic projection. But if we radicalize the Kantian primacy of practical reason in the way that Brandom sees Hegel as doing, then all our theoretical accounts of nature, including those commonly regarded as value-free — and everything else we think, feel, and do — ultimately have a dependency on our inquiries into value and normativity.

From a Kantian point of view, our only access to objective nature is through our rational, discursive understanding. The very objectivity we attribute to nature depends on the objectivity of our understanding of it. Objectivity itself is a normative attitude. I think Kant and Aristotle ultimately agree in recognizing that we don’t have direct access to how things are in themselves, and that how things are in themselves is always a matter of discursive inference, in which the last word is never said.

Hegel emphasizes that the objectivity of understanding we achieve in this way is not a private possession, but something larger than us in which we participate. (See also Teleology After Kant.)

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.

Beauty and Discursivity

Plotinus was a huge inspiration for me in my youth. Revisiting a piece of his Enneads just now, I am again struck by the majesty of his thought and writing. These days I have a much more positive view of discursive reasoning, but I first wanted to let him speak for himself.

I still agree that there is far more to knowledge and understanding than an accumulation of propositions. But as a teenager, I definitely considered step-by-step reasoning to be something inferior to the kind of holistic intellectual intuition Plotinus emphasizes when he talks about Intellect. The latter I considered to be the true source of insight — “silent mind before talking mind”.

Nowadays, I think that kind of unitary vision is achievable only as the crowning result of much patient work. I no longer take it to be the original source that discursive reasoning imitates in an inferior way. Intellect or Reason does form a relational whole, and the whole is more important than the parts. But today I would emphasize that the relational whole is an articulated whole, and it is the articulation — the making of connections — that is the real essence.

From many connections, we get larger unities. Larger unities are still the goal, but the work of making connections is what makes such fused views possible. The contemplation of well-formed wholes by the silent mind of an embodied human depends on prior work that must include open discursive questioning and reasoning, if the result is to be genuine.

Aristotle made a vitally important distinction between what is first in itself and what is first for us. To directly aim for the highest truth in itself while being dismissive of what is “first for us” is to disregard our nature as rational animals. Put another way, to directly aim for the highest truth is simply to miss it. This is the kind of illegitimate shortcut that Plotinus himself criticized the gnostics for.

We rational animals need the “long detour” of dialectic to properly grasp any kind of real truth. Otherwise, our visionary experiences will just be fever dreams of the sort that incite fanatics. The goal is not just immediacy but mediated immediacy, as Hegel would say. I think Plotinus at least partially recognized this.

To no longer regard things in the manner of “a spectator outside gazing on an outside spectacle” is to overcome naive dichotomies of subject and object. To really do this, we have to clear our minds of prejudice, not just do meditative exercises to silence internal dialogue. Clearing our minds of prejudice is what requires the long detour.

Imagination: Aristotle, Kant

In the glossary to his translation of Aristotle’s On the Soul, Joe Sachs nicely summarizes the various roles of phantasia or “imagination” in Aristotle:

“A power of the soul that perceives appearances when perceptible things are absent and thinks without distinguishing universals (429a 4-8, 434a 5-11). The imagination is identified in On Memory and Recollection as the primary perceptive power of the soul (449b 31 – 450a 15). Thus, many activities discovered in On the Soul may be collected and attributed to the imagination, such as perceiving common and incidental objects of the senses, being aware that we are perceiving, discriminating among the objects of the different senses (425a 14 – b 25), distinguishing flesh or water (429b 10-18), and perceiving time (433b 7). Also, implicit within the power of imagination to behold images (phantasmata), there must be imagination in a second sense, eikasia, by which we can see an image as an image (eikon) or likeness (On Memory and Recollection 450b 12-27)” (pp. 194-195; citations in original).

In the above, I would particularly highlight “thinking without distinguishing universals” and “being aware that we are perceiving”. Imagination — and not intellect, for instance — seems to me to be the primary source suggested in Aristotle for what we, following Locke, call “consciousness”. Also noteworthy is language suggestive of what Kant would later call synthesis.

The vital implication here is that the closest analogue of “consciousness” in Aristotle comes into being not as a transparent medium of representation, but rather as a shifting collection of concrete forms in imagination. Further, the forms we experience are not just passively received, but actively organized and discriminated at a pre-conscious level. Thus when Aristotle says — as he also does — that, e.g., the eye is essentially passive in receiving forms as differentiations in received light — this latter is intended at a purely physical level, and is far from providing a full account of, e.g., visual perception by a human.

Prior to Descartes’ confabulation of scholastic “cogitation” and “intellection”, concrete human psychic activity or “cogitation” was generally recognized as having its roots in imagination. Intellection was understood to have a more specialized role, focused on the constitution of universals. However, attempts to reconcile Aristotle with Plotinus and Proclus in the Arabic tradition, and then with Augustine and pseudo-Dionysius in the Latin tradition, provided a background that was ultimately very supportive toward Aquinas’ strong claim that intellect must after all be understood as the leading part of the individual human soul, morally responsible for all its concrete thoughts and actions. This made it far more plausible for Descartes to take the further step — which Locke followed — of simply identifying cogitation and intellection. The self-transparency of the cogito in Descartes and of consciousness in Locke, respectively — along with their identification with intellection — served to marginalize the role of forms in imagination in their conceptions of “mind”.

A very important feature of Kant’s work that is relatively little appreciated is that he restored a central role for “imagination” in philosophical psychology and anthropology. For Kant, humans can have neither direct knowledge of empirical facts or objects, nor any knowledge of transcendent realities. All intellection and knowledge are discursive, as I think Aristotle would have agreed. We have immediate though “blind” intuition of a sensible manifold, but intellectual intuition is an oxymoron, because intellection is inherently discursive. And in between the synthesis of initial sensory apprehension in intuition and the synthesis of recognition in the concept (Kant’s equivalent for intellection) comes a crucial synthesis of reproduction in imagination. Though his terminology is quite different, Kant not only recovers but even expands upon the role that imagination played in Aristotle.

In Kant and the Capacity to Judge, Beatrice Longuenesse carefully develops what Kant says about imagination in the Critique of Pure Reason. This is a major dimension of her book, so I can only give a flavor of it here.

“The imagination ‘in which’ there is reproduction is not the imagination as a faculty or power (Einbildungskraft), but the representation produced by this faculty (Einbildung)” (p. 35). Though Kant uses the terminology of representation, this effectively refers to the same forms in imagination that Aristotle emphasized.

“[Kant] shows that these acts of combination can contribute to the cognition of a phaenomenon, an object distinct from the ‘indeterminate object of empirical intuition’ (Erscheinung [or mere appearance]), only if they all belong to one and the same act of synthesis of the spatiotemporal manifold. The form of this act is determined a priori by the nature of our mind, and its outcome is threefold: the manifold of intuition represented ‘as’ manifold, the representation of imagination (Einbildung) emerging from empirical associations, and finally the universal representation or concept, under which particular representations are subsumed. This act is that very act of synthesis which Kant, in section 10, attributes to the imagination, in the A Deduction [of the categories] more precisely to transcendental imagination, and which in the B Deduction he calls synthesis speciosa, figurative synthesis” (pp. 35-36).

As usual in Kant, “transcendental” means not metaphysical, but simply constitutive in a way that is not reducible to empirical events. Longuenesse points out that imagination in Kant is not merely reproductive, but also productive. In any case, for Kant not only the logical “matter” but also the elaborated form of our fully constituted experience owes a great deal to imagination, and a recognition of this — as opposed to the assumption of a putative transparency of consciousness — is fundamental to the “Critical” attitude Kant aimed to promote. Here I am using “form” in a sense more Aristotelian than Kantian.
