Priestley and Kant on materialism

ABSTRACT

Kant maintains in the Critique of Pure Reason that both materialism and spiritualism cannot explain our existence. This paper argues that Kant’s relation to (psychological) materialism is more complex than this rejection suggests and is usually thought, and it evaluates this relation in a new and more positive light. The paper shows that Priestley anticipates some of Kant’s arguments against rationalist psychology, and that Kant’s rejection of materialism does not commit him to an immaterialist metaphysics of the soul. These arguments involve a discussion of the problem of the unity of consciousness and of notions such as simplicity and identity.
