A Stanford University Press classic.

Thomas C. Vinci aims to reveal and assess the structure of Kant's argument in the Critique of Pure Reason called the "Transcendental Deduction of the Categories." At the end of the first part of the Deduction in the B-edition Kant states that his purpose is achieved: to show that all intuitions in general are subject to the categories. On the standard reading, this means that all of our mental representations, including those originating in sense-experience, are structured by conceptualization. But this reading encounters an exegetical problem: Kant states in the second part of the Deduction that a major part of what remains to be shown is that empirical intuitions are subject to the categories. How can this be if it has already been shown that intuitions in general are subject to the categories? Vinci calls this the Triviality Problem, and he argues that solving it requires denying the standard reading. In its place he proposes that intuitions in general and empirical intuitions constitute disjoint classes and that, while all intuitions for Kant are unified, there are two kinds of unification: logical unification vs. aesthetic unification. Only the former is due to the categories. A second major theme of the book is that Kant's Idealism comes in two versions-for laws of nature and for objects of empirical intuition-and that demonstrating these versions is the ultimate goal of the Deduction of the Categories and the similarly structured Deduction of the Concepts of Space, respectively. Vinci shows that the Deductions have the argument structure of an inference to the best explanation for correlated domains of explananda, each arrived at by independent applications of Kantian epistemic and geometrical methods.

Immanuel Kant’s ‘Transcendental Deduction of the Categories’ addresses issues centrally debated today in philosophy and in cognitive sciences, especially in epistemology, and in theory of perception. Kant’s insights into these issues are clouded by pervasive misunderstandings of Kant’s ‘Deduction’ and its actual aims, scope, and argument. The present edition with its fresh and accurate translation and concise commentary aims to serve these contemporary debates as well as continuing intensive and extensive scholarship on Kant’s Critique of Pure Reason. Two surprising results are that ‘Transcendental Deduction’ is valid and sound, and it holds independently of Kant’s transcendental idealism. This lucid volume is interesting and useful to students, yet sufficiently detailed to be informative to specialists.

The first collective commentary in English on Kant's landmark 1871 publication.

Henry E. Allison presents an analytical and historical commentary on Kant s transcendental deduction of the pure concepts of the understanding in the Critique of Pure Reason. He argues that, rather than providing a new solution to an old problem (refuting a global skepticism regarding the objectivity of experience), it addresses a new problem (the role of a priori concepts or categories stemming from the nature of the understanding in grounding this objectivity), and he traces the line of thought that led Kant to the recognition of the significance of this problem in his 'pre-critical' period. Allison locates four decisive steps in this process: the recognition that sensibility and understanding are distinct and irreducible cognitive powers, which Kant referred to as a 'great light' of 1769; the subsequent realization that, though distinct, these powers only yield cognition when they work together, which is referred to as the 'discursivity thesis' and which led directly to the distinction between analytic and synthetic judgments and the problem of the synthetic a priori; the discovery of the necessary unity of apperception as the supreme norm governing discursive cognition; and the recognition, through the influence of Tetens, of the role of the imagination in mediating between sensibility and understanding. In addition to the developmental nature of the account of Kant s views, two distinctive features of Allison'sreading of the deduction are a defense of Kant s oft criticized claim that the conformity of appearances to the categories must be unconditionally rather than merely conditionally necessary (the 'non-contingency thesis') and an insistence that the argument cannot be separated from Kant s transcendental idealism (the 'non-separability thesis').

This book reinterprets key parts of the Critique of Pure Reason in view of Kant's sustained engagement with Wolffian metaphysics.

This book is organized as a commentary following the text of the B-Transcendental Deduction line by line. In so doing, it becomes evident that each step of the Deduction necessarily follows from the preceding step and is grounded in it, although not in the way the steps of a formal-logic deduction are. The primary hypothesis of this book is that the succession of steps is but the unfolding of the Principle of Apperception. The commentary assumes that the entire argument of the B-Deduction consists in a progressive enlargement and enrichment of the Principle of Apperception. The book draws its unity from this assumption, as well as from the strong concatenation of the successive steps. Focusing the monograph on the very narrow problem of the B-Deduction’s argumentative structure enables the author to settle several controversial questions, such as, for instance, those originating in the division of the B-Deduction in two steps, and that of the function of the doctrine of the transcendental subject expounded in paragraphs 24 and 25. Its comprehensive explanation of the Transcendental Deduction ensures that the book will be helpful to students of Kantian Philosophy, while its focus on a single problem will make it useful to specialists. Kant’s B Deduction is part of the Kantian Questions series.
