Michel de Montaigne was the originator of the modern essay form; in these diverse pieces he expresses his views on relationships, contemplates the idea that man is no different from any animal, argues that all cultures should be respected, and attempts, by an exploration of himself, to understand the nature of humanity.

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.
