Abstract

Kant's system of transcendental idealism is based upon the idea that cognition is discursive, in that it involves the separate faculties of intuition and the understanding. This account of cognition I call the 'discursivity thesis.' Kant, however, provides little argument in favor of this thesis, instead taking it to be an assumption about the nature of human cognition. Despite discursivity's initial appeal, the lack of an argument on its behalf leaves it open to skeptical challenge. In the dissertation, I examine one such challenge, developed by Kant's contemporary Salomon Maimon. Maimon claims that Kant's assumption of discursivity is both ungrounded and problematic, for it leads to insuperable problems about the nature of cognition. After an introductory chapter, I begin the reconstruction of this challenge by presenting in Chapter II the notion of discursivity, both in its Scholastic employments and as used by Kant. I then turn in Chapter III to an examination of the arguments of the Aesthetic section of the Critique of Pure Reason, which, I claim, do not obviate Maimon's objections. Rather, the heart of the debate is found in the issues of the Deduction and Principles, which I address in Chapters IV and V respectively. Here I argue that Kant's assumption of discursivity can be shown to lead to a dilemma involving the application of a priori categories to particular a posteriori intuitions---Kant's cognitive dualism precludes an account of the interaction between separate cognitive elements. I try to soften the blow of this charge by presenting, in Chapter VI, a way in which Kant might accommodate Maimon's skepticism by granting a type of uncertainty about the application to the categories. I conclude in Chapter VII by looking at Maimon's influence on Fichte, and by noting the relevance of Maimonian skepticism for contemporary debates about the nature of Givenness
