Winfield has achieved a fundamental, systematic and comprehensive re-thinking of the problem of mind. Grounded in a critical reconstruction of Aristotle and Hegel, it draws upon a broad range of ancient, modern and contemporary philosophers to establish that mind must necessarily be materially embodied in living, animal organism, and must manifest itself in the three distinguishable phases of psyche, consciousness and intelligence, thoroughly exploring the sometimes surprising implications of such an analysis. It answers the need for a thoroughly non-Cartesian account of mind better than any available alternative. I would not teach the philosophy of mind again without using this work.
