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.
