The Master and His Emissary: The Divided Brain and the Making of the Western World, 2nd Edition

A pioneering exploration of the differences between the brain's right and left hemispheres and their effects on society, history, and culture—"one of the few contemporary works deserving classic status" (Nicholas Shakespeare, The Times, London)

"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

"I know of no better exposition of the current state of functional brain neuroscience."—W. F. Bynum, TLS

Why is the brain divided? The difference between right and left hemispheres has been puzzled over for centuries. Drawing upon a vast body of brain research, the renowned psychiatrist, author, and thinker Iain McGilchrist reveals that the difference between the two sides is profound—two whole, coherent, but incompatible ways of experiencing the world. The detail-oriented left hemisphere prefers mechanisms to living things and is inclined to self-interest, while the right hemisphere has greater breadth, flexibility, and generosity.

In the second part of his book, McGilchrist takes the reader on a journey through the history of Western culture, illustrating the tension between these two worlds as revealed in the thought and belief of thinkers and artists from the ancient to the modern, from Aeschylus to Magritte. He ultimately argues that, despite its inferior grasp of reality, the left hemisphere is increasingly taking precedence in today's world—with potentially disastrous consequences.
