Here are three exhilarating and inspiring essays in which the great twentieth-century political philosopher argues that there can be no freedom without politics, and no politics without freedom. 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.
