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. Francis Bacon's landmark writings on subjects ranging from anger and ambition, marriage and money to envy and empire established him as the founding father of modern scientific thinking, with his rejection of superstition and his emphasis on proof and experiment, rational enquiry and reasoned argument.
