The name of John Maynard Keynes is still the focus of political and economic controversy, and in the course of it, "what Keynes really meant" has suffered much distortion. This book represents a quest for the historical Keynes. It follows the story of an argument which arose out of the performance of the British economy in the period of depression between the wars and provides an account of Keynes's thinking in the years that led up to the General Theory, making it comprehensible to specialists and non-specialists alike.
