Abstract

Kant's transcendental deduction yields twelve and only twelve categories, but behind the argument lie two assumptions: 1) newtonian physics gives unalterable and certain knowledge of phenomena; 2) the subject-predicate logic is the correct tool for the analysis of knowledge. this article examines the place of both assumptions in kant's doctrine and the relevance of each today. both assumptions must be discarded, and with them goes the rigidity of the categories; but the article shows how kant's important insights into the place of the categories in knowledge can be salvaged
