Abstract

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.
