In this unique exploration of the mysteries of the human brain, Roger Bartra shows that consciousness is a phenomenon that occurs not only in the mind but also in an external network, a symbolic system. He argues that the symbolic systems created by humans in art, language, in cooking or in dress, are the key to understanding human consciousness. Placing culture at the centre of his analysis, Bartra brings together findings from anthropology and cognitive science and offers an original vision of the continuity between the brain and its symbolic environment. The book is essential reading for neurologists, cognitive scientists and anthropologists alike.
