Describing bizarrely popular Victorian street slang, the madness of crowds, stock market mania (from the South Sea Bubble to Tulip fever), popular fashions, fads, crazes, schemes and scams, this brilliantly entertaining and ever-more relevant study of human folly shows that we are always susceptible to hysteria and bamboozlement. 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.
