This investigation of religion by greatest psychoanalyst of the twentieth-century explores the role faith can take in the life of man, what it can mean to us and why as a species we are inclined towards it. Throughout history, some books have changed the world. They have transformed the way we see ourselves and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are.
