"Directed to scholars and senior-level graduate students, this book is an iconoclastic survey of the history of dualism and its impact on contemporary cognitive psychology. In it, William Uttal argues that much of modern cognitive or mentalist psychology is built upon a crypto-dualism - the idea that the mind and brain can be thought of as independent entities. This notion of dualism is so pervasive that it covertly influences many aspects of modern science." "To support the argument, the author explores the history of dualism over 100,000 years, from the Paleolithic time until modern philosophical and psychological thinking."--BOOK JACKET.
