Created by the seventeenth-century philosopher and mathematician Pascal, the essays contained in Human Happiness are a curiously optimistic look at whether humans can ever find satisfaction and real joy in life - or whether a belief in God is a wise gamble at best. 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.
