A new edition of the bestselling classic - published with a special introduction to mark its 10th anniversary

This pioneering account sets out to understand the structure of the human brain - the place where mind meets matter. Until recently, the left hemisphere of our brain has been seen as the `rational' side, the superior partner to the right. But is this distinction true?

Drawing on a vast body of experimental research, Iain McGilchrist argues while our left brain makes for a wonderful servant, it is a very poor master. As he shows, it is the right side which is the more reliable and insightful. Without it, our world would be mechanistic - stripped of depth, colour and value.

"A veritable tour de force, gradually and skilfully revealed. I know of no better exposition of the current state of functional brain neuroscience."-W. F. Bynum, TLS

"A profound examination."-Philip Pullman

"Persuasively argues that our society is suffering from the consequences of an over-dominant left hemisphere losing touch with its natural regulative `master' the right. Brilliant and disturbing."-Salley Vickers, a Guardian Best Book of the Year

"Clear, penetrating, lively, thorough and fascinating. . . . I couldn't put it down."-Mary Midgley, The Guardian
