Introduction

A tour de force of neuroscience and philosophy, Iain McGilchrist’s The Master and His Emissary speaks to everyone searching for happiness, meaning and understanding in the modern world. For millennia humans have speculated upon the differences between the left and right hemispheres of the brain. Why did evolution lead to humans and many other animals developing two cerebral hemispheres, separated by a groove? No neuroscientist would dispute that there are significant differences; but until now, no-one has understood why. Dr Iain McGilchrist has an empirical answer to this question – and his ideas have profound consequences for how humans understand themselves and their place in the world. This conversation between Dr McGilchrist and science journalist David Malone explores how the competition between the two hemispheres has shaped civilisation and progress and now, in our hyper-rationalist age, threatens to undermine the deepest and most sacred human values.
