Tracing around the world the changing perspectives of economists, philosophers, politicians and polemicists, historian Richard Whatmore argues that, for figures as diverse as David Hume, Edmund Burke, Adam Smith and Mary Wollstonecraft, the Enlightenment was a profound failure. They had strived to replace superstition with reason, fanaticism with toleration, but witnessed instead terror and revolution, corruption, gross commercial excess and the continued growth of violent empire. This book is a lucid exploration of disillusion and intellectual transformation, a brilliant meditation on our continued assumptions about the past, and a glimpse of the different ways our world might be structured.
