'Many of the greatest economic evils of our time are the fruits of risk, uncertainty, and ignorance' John Maynard Keynes was the most influential economist, and one of the most influential thinkers, of the twentieth century. He overturned the orthodoxy that markets were optimally self-regulating, and instead argued for state intervention to ensure full employment and economic stability. This new selection is the first comprehensive single-volume edition of Keynes's writings on economics, philosophy, social theory and policy, including several pieces never before published. Full of irony and wit, they offer a dazzling introduction to a figure whose ideas still have urgent relevance today. Edited with an introduction and commentary by Robert Skidelsky
