We live within a spectacle of empty clothes and unworn masks. In this series of remarkable pieces from across his career, John Berger celebrates and dissects the close links between art and society and the individual. Few writers give a more vivid and moving sense of how we make art and how art makes us. GREAT IDEAS. 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.
