The Germans were over this house last night and the night before that. Here they are again. It is a queer experience, lying in the dark and listening to the zoom of a hornet, which may at any moment sting you to death. It is a sound that interrupts cool and consecutive thinking about peace. Yet it is a sound - far more than prayers and anthems - that should compel one to think about peace. Unless we can think peace into existence we - not this one body in this one bed but millions of bodies yet to be born - will lie in the same darkness and hear the same death rattle overhead.' 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.
