Are humans unique? Can animals think as we do? Will machines ever be conscious? What is free will? For centuries, attempts to answer these questions have been the stuff of theological and philosophical dispute, as well as bar-room debate. Now scientists claim they can solve these riddles of human existence, once and for all. Man, Beast and Zombie is a thrillingly original and accessible book. Huge in its reach and powerful in its grasp, it draws on cutting-edge sciences such as evolutionary biology, cognitive psychology and Artificial Intelligence to assess what, precisely, they can and cannot explain about human nature. Kenan Malik explains the histories of these sciences and the philosophies that underpin them and analyses the complex relationship between human beings, animals and machines to explore what really makes us human.
