This book is about its subtitle: 'A History of Explanations in Psychology and Physics'. To bring that history up to date, one should point out that this year's Nobel Prizes in Medicine went to three men honoured for their contribution to our knowledge of the brain: Roger Sperry from Cal Tech and David Hubel and Torsten Wiesel from Harvard. Their discoveries are stunning, counter-intuitive and of no immediate practical consequence. They are therefore widely unknown outside their fraternity. A further reason for their obscurity is that the hard facts they have skilfully revealed appear to run exactly in the opposite direction to the requirements of those who write books about the mind. They have studied the sequence of events which link the eye to the brain. They have tapped into the mechanisms by which the light from objects in the world is related to sensations and perceptions and behaviour.
