In doing so, he argues that we have become enslaved to an account of things dominated by the brain’s left hemisphere, one that blinds us to an awe-inspiring reality that is all around us, had we but eyes to see it. He suggests that in order to understand ourselves and the world we need science and intuition, reason and imagination, not just one or two; that they are in any case far from being in conflict; and that the brain’s right hemisphere plays the most important part in each. And he shows us how to recognise the ‘signature’ of the left hemisphere in our thinking, so as to avoid making decisions that bring disaster in their wake.

Following the paths of cutting-edge neurology, philosophy and physics, he reveals how each leads us to a similar vision of the world, one that is both profound and beautiful – and happens to be in line with the deepest traditions of human wisdom. It is a vision that returns the world to life, and us to a better way of living in it: one we must embrace if we are to survive.

“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, Times Literary Supplement

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.
