Gary Hatfield draws together his work on the science and philosophy of visual perception and cognition, including spatial perception, colour perception and qualia, object perception, the structure of conscious experience, physiological reduction and the role of neuroscience, the history of theories of vision, and the status of introspective methods. Trained both in philosophy and experimental psychology (mainly vision research) Hatfield is equally at home in both disciplines and brings an unusually well-grounded approach to the many foundational issues discussed... Hatfield's coverage of much of the mainstream literature and its historical antecedents is impressive... this book provides a rich and essential source of study.
