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.

Voltaire’s short, radical and iconoclastic essays on philosophical ideas from angels to idolatry, miracles to wickedness, make wry observations about human beliefs, and mock hypocrisy and extravagant piety – his call to his fellow men to act with reason and see through the lies they are fed by their leaders has provided inspiration to freethinkers everywhere.
