ABSTRACT At the core of Kant’s theoretical philosophy lies the deduction of the categories: his effort to secure the distinctiveness of sensibility and understanding and to provide a necessary relation between the domains of these faculties. The argument for this claim is presented in two different versions - i.e., the A and B editions of the Critique of pure reason - and is one of the most puzzling in Kant’s corpus. The common view in the literature that considers the importance (...) of the A-deduction and tries to present its structure is that it must be understood in the light of the B-deduction argument. I aim at contesting this view and offering an internal reconstruction of the A-deduction argument which reveals its unique methodology. The thesis advanced is that the A-deduction follows an analytical methodology and that this methodology does not allow the accomplishment of the task of the deduction stated in Kant’s effort. At first, Kant’s retrospect of the A-deduction is taken into account. After that, a consideration of the part of the argument described as ‘subjective deduction’ is carried out. (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.
