Whether calling for an end to the capitalist system, addressing the crowds after the Russian Revolution, or attacking Stalin during his years of exile, Trotsky's speeches give an extraordinary insight into a man whose words and actions determined the fates of millions. 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.
