In this seminal contribution to Kant studies, originally published in 1982, Karl Ameriks presented the first thorough survey and evaluation of Kant's theory of mind. Ameriks focuses first on Kant's discussion of the Paralogisms in the Critique of Pure Reason, and examines how the themes raised there are treated in the rest of Kant's writings. It is demonstrated that Kant developed a theory of mind that is much more rationalistic and defensible than most interpreters have allowed, a theory that is of great significance for the understanding of his philosophy as a whole. Kant's Theory of Mind is now brought up to date with a substantial preface and postscript, as well as many additional references to the literature. This expanded edition will enhance the book's continued value for today's Kantians and philosophers of mind.
