Ryle argues that the language traditionally used to describe the relationship between mind and body amounts to nothing less than a massive 'category mistake'. Terms such as 'mind', 'thought' and 'belief' do not refer to a mysterious, inner world but simply describe certain actions and our ability to perform them. Even the act of imagining, argues Ryle, should be understood as an outward rather than inner performance, as when we watch a boxer shadow-boxing an imaginary opponent before entering the ring. On this basis Ryle overturns some long-held assumptions about language and knowledge, including knowledge of other people's minds and launched the new movement of philosophical behaviourism. Ryle builds his case via an erudite and beautifully written account of the will, emotion, self-knowledge, sensation and observation, imagination and the intellect. Some of the problems he tackles, such as the distinction between 'knowing how and knowing that', challenged some of the bedrock assumptions of philosophy and continue to exert important influence on contemporar philosophy. A classic work of philosophy and psychology The Concept of Mind is essential reading for anyone interested in the nature of the mind and human behaviour. | The Concept of Mind by Gilbert Ryle, Hardcover | Indigo Chapters
