This book is a tour-de-force on how human consciousness may have evolved. From the "phantom pain" experienced by people who have lost their limbs to the uncanny faculty of "blindsight," Humphrey argues that raw sensations are central to all conscious states and that consciousness must have evolved, just like all other mental faculties, over time from our ancestors' bodily responses to pain and pleasure. ' "A wonderful book-brilliant, unsettling, and beautifully written. Humphrey cuts bravely across the currents of contemporary thinking, opening up new vistas on old problems and offering a feast of provocative ideas. Nobody else brings such an astonishing range of knowledge to bear on these issues." -- Daniel Dennett "Humphrey is one of that growing band of scientists who beat literary folk at their own game." -- Daily Telegraph Nicholas Humphrey, Professor of Psychology at The New School for Social Research and Research Fellow in Philosophy at the London School of Economics, is a distinguished theoretical psychologist widely known for his work on the evolution of the mind. He is the author of Leaps of Faith, Consciousness Regained, and The Inner Eye.
