Abstract

In the Critique of Pure Reason Kant attempts to solve two problems about our knowledge of the world. First, how can we know any necessary truths about the world, such as the principle that every event must have a cause? Second, how can I know that things other than I exist at all? Kant’s strategy for dealing with both these problems is to repudiate the kind of distinction that Descartes and Hume had made between self-knowledge and our knowledge of ‘outer’ things. Kant’s innovation is to distinguish sharply between two sides of what his predecessors understood as self-knowledge: ‘inner sense’ and ‘apperception.’ This paper shows how Kant's conception of ‘apperception’ is meant to overcome Humean skepticism, and how ‘inner sense’ is meant to overcome Cartesian skepticism; I then touch upon a complication in Kant’s view of the relation between apperception and inner sense, a complication which relates directly to the problem of the ‘thing in itself.’
