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. One of the greatest explorations of sin, epiphany, and redemption ever written, the Confessions of Saint Augustine continue to shape our ideas with their passionate declaration of the life-changing power of faith.
