The ideas of Ludwig Wittgenstein and Gilbert Ryle have had a major influence on the work of Anthony Kenny, who has explored many aspects of the philosophy of mind in a series of books over the past twenty-five years. Modelled on the structure of Ryle's The Concept of Mind, this book forges Kenny's ideas on philosophical psychology into a systematic whole. Written in a style that avoids jargon and academic controversy, it is both accessible to the general reader and challenging for the specialist.
