"This book is unique. I know of no other which so artfully tackles two of the greatest mysteries of modern science, quantum mechanics, and consciousness. It has long been suspected that these mysteries are somehow related: the authors’ treatment of this thorny and controversial issue is honest, wide-ranging, and immensely readable. The book contains some of the clearest expositions I have ever seen of the strange and paradoxical nature of the quantum world. Quantum Enigma is a pleasure to read, and I am sure it is destined to become a classic."
