Kant made a number of highly original discoveries about the mind - about its ability to synthesise a single, coherent representation of self and world, about the unity it must have to do so, and about the mind's awareness of itself and the semantic apparatus it uses to achieve this awareness. The past fifty years have seen intense activity in research on human cognition. Even so, Kant's discoveries have not been superseded, and some of them have not even been assimilated into current thinking. That is particularly true of his work on unity and on the semantic apparatus of self-awareness. The first four chapters of this book present a comprehensive overview of Kant's model for non-specialists, an overview largely unencumbered by detailed exegesis. The work then offers a close study of five major discussions of the mind in the Critique of Pure Reason and Anthropology.
