Describing Tolstoy's crisis of depression and estrangement from the world, A Confession is an autobiographical work of exceptional emotional honesty. It describes his search for 'a practical religion not promising future bliss but giving bliss on earth'. Although A Confession led to his ex-communication, it also resulted in a large following of Tolstoyan Christians springing up throughout Russia and Europe. 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.
