How is consciousness possible? What biological purpose does it serve? Why do we value it so highly? In Soul Dust the psychologist Nicholas Humphrey, a leading figure in consciousness research, returns to the front-line with a startling new theory. Consciousness, he argues, is nothing less than a magical-mystery show that we stage for ourselves inside our own heads. This self-made show lights up the world for us, making us feel special and transcendent. Tightly argued, intellectually gripping and a joy to read, Soul Dust is a keenly anticipated book that provides answers to the deepest questions. It dovetails the 'hard problem of consciousness' with the matters that obsess us all - the fear of death, how life should be lived. Resting firmly on neuroscience and evolutionary theory, it is an uncompromising yet life-affirming work that never loses sight of the majesty and mystery of consciousness.
