Abstract Both parties in the active philosophical debate concerning the conceptual character of perception trace their roots back to Kant's account of sensible intuition in the Critique of Pure Reason. This striking fact can be attributed to Kant's tendency both to assert and to deny the involvement of our conceptual capacities in sensible intuition. He appears to waver between these two positions in different passages, and can thus seem thoroughly confused on this issue. But this is not, in fact, the (...) case, for, as I will argue, the appearance of contradiction in his account stems from the failure of some commentators to pay sufficient attention to Kant's developmental approach to philosophy. Although he begins by asserting the independence of intuition, Kant proceeds from this nonconceptualist starting point to reveal a deeper connection between intuitions and concepts. On this reading, Kant's seemingly conflicting claims are actually the result of a careful and deliberate strategy for gradually convincing his readers of the conceptual nature of perception.

The deduction of categories in the 1781 edition of the Critique of the Pure Reason (A Deduction) has “two sides”—the “objective deduction” and the “subjective deduction”. Kant seems ambivalent about the latter deduction. I treat it as a significant episode of Kant’s thinking about categories that extended from the early 1770s to around 1790. It contains his most detailed answer to the question about the origin of categories that he formulated in the 1772 letter to Marcus Herz. The answer is (...) that categories are generated a priori through a kind of intellectual “epigenesis”. This account leaves unexplained why precisely such and such categories should be generated. While this observation caused Kant to worry about the hypothetical status of the subjective deduction in 1781, he would come to acquiesce in the recognition that the ground of the possibility of categories is itself inscrutable. I call this his “methodological skepticism”. (shrink)

Kant's A-Edition objective deduction is naturally (and has traditionally been) divided into two arguments: an " argument from above" and one that proceeds " von unten auf." This would suggest a picture of Kant's procedure in the objective deduction as first descending and ascending the same ladder, the better, perhaps, to test its durability or to thoroughly convince the reader of its soundness. There are obvious obstacles to such a reading, however; and in this chapter I will argue that the (...) arguments from above and below constitute different, albeit importantly inter-related, proofs. Rather than drawing on the differences in their premises, however, I will highlight what I take to be the different concerns addressed and, correspondingly, the distinct conclusions reached by each. In particular, I will show that both arguments can be understood to address distinct specters, with the argument from above addressing an internal concern generated by Kant’s own transcendental idealism, and the argument from below seeking to dispel a more traditional, broadly Humean challenge to the understanding’s role in experience. These distinct concerns also imply that these arguments yield distinct conclusions, though I will show that they are in fact complementary. (shrink)

I argue that Kant’s primary epistemological concern in the Critique of Pure Reason’s transcendental deduction is empirical cognition. I show how empirical cognition is best understood as “rational sensory discrimination”: the capacity to discriminate sensory objects through the use of concepts and with a sensitivity to the normativity of reasons. My dissertation focuses on Kant’s starting assumption of the transcendental deduction, which I argue to be the thesis that we have empirical cognition. I then show how Kant’s own subjective deduction (...) fleshes out his conception of empirical cognition and is intertwined with key steps in the transcendental deduction’s arguments that the categories have objective validity and that we have synthetic a priori cognition.

In the A-preface of the Critique of Pure Reason, Kant kindly warns his readers to pay special attention to the chapter on the “Deduction of the Pure Concepts of the Understanding.” Looking to mitigate the reader's effort, Kant goes on to explain the chapter's methodology, suggesting that the inquiry will have “two sides.” One side deals with the “objective validity” of the pure categories of the understanding; he calls this the “objective deduction.” The other deals with the powers of cognition (...) on which the understanding rests; he calls this the “subjective deduction.” Having gone to such great lengths to outline his method ahead of time, it comes as no small surprise that the actual chapter offers no clear indication of where the two deductions are located. In this essay, I attempt to solve this puzzle. On the way, I engage with both traditional and recent interpretations of the subjective deduction, arguing that they fail—in one way or another—to satisfy the criteria that Kant develops in the preface.

Dennis Schulting offers a thoroughgoing, analytic account of the first half of the Transcendental Deduction of the Categories in the B-edition of Kant's Critique of Pure Reason that is different from existing interpretations in at least one important aspect: its central claim is that each of the 12 categories is wholly derivable from the principle of apperception, which goes against the current view that the Deduction is not a proof in a strict philosophical sense and the standard reading that in (...) the Deduction Kant only gives an account of the global applicability of the categories to experience. This novel approach enables a reappraisal of Kant's controversial claim that transcendental self-consciousness is not only a necessary condition of objective experience but also sufficient for it. The book provides an extensive analysis of Kant's theory of transcendental apperception and also explains why the argument of the Transcendental Deduction is both a regressive and a progressive argument.

This book is a comprehensive exposition of the Transcendental Deduction of the Categories in both editions of Kant’s Critique of Pure Reason.

This paper develops a new functionalist interpretation of Kant that aims to unify his cognitive psychology with transcendental idealism. It argues that Kant’s faculty of cognition describes neither the phenomenal nor the noumenal mind, but a theoretical construct of the transcendental subject, comparable to the abstract Turing machine. This interpretation can be called “transcendental functionalism,” which determines what functions the mind has to realize if it is to be capable of objective cognition. Transcendental functionalism resolves problems associated with other functionalist (...) interpretations of Kant by drawing a systematic distinction between transcendental cognitive functions and their empirical realizations. While transcendental functions stipulate abstract conceptual requirements, their empirical counterparts realize the functional constraints in appearances within the spatiotemporal and causal framework. This distinction also allows a better explanation of why Kant abandoned the subjective deduction of categories in the B-deduction. (shrink)
