A Treatise on Probability: The Connection Between Philosophy and the History of Science

John Maynard Keynes, 1st Baron Keynes, CB (1883-1946) was a British economist whose ideas have profoundly affected the theory and practice of modern macroeconomics, as well as the economic policies of governments. He greatly refined earlier work on the causes of business cycles, and advocated the use of fiscal and monetary measures to mitigate the adverse effects of economic recessions and depressions. His ideas are the basis for the school of thought known as Keynesian economics, and its various offshoots. "A Treatise on Probability," originally published in 1921, launched the "logical-relationist" theory.
