Published with an introduction by Robert Skidelsky: "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 significant thinkers of the twentieth century. He challenged the orthodoxy that markets are optimally self-regulating and instead advocated for government intervention to ensure full employment and economic stability. This new selection is the first comprehensive single-volume edition of Keynes' writings on economics, philosophy, social theory, and politics, including several previously unpublished texts. Full of irony and wit, they provide a fascinating introduction to a figure whose ideas remain urgently relevant today.
