This book introduces students to the principal issues in the philosophy of mind by tracing the history of the subject from Plato and Aristotle through to the present day. Over forty primary source readings are included. Extensive commentaries from the editors are provided to guide student readers through the arguments and jargon and to offer necessary historical context for the readings. The new third edition examines some of the most exciting recent developments in the field, including advances in theories about the mind's relation to action and agency. Previous editions of this book, published under the title A Historical Introduction to the Philosophy of Mind, have been praised and widely taught for more than two decades.
