Peter Clarke re-examines the full trajectory of Keynes public career from his role at Versailles to Bretton Woods. He reveals how Keynes's insights as an economic theorist were rooted in his wider intellectual and cultural milieu including Bloomsbury and his friendship with Virginia Woolf as well as his involvement in government business. Keynes in Action uncovers a much more pragmatic Keynes whose concept of 'truth' needs to be interpreted in tension with an acknowledgement of 'expediency' in implementing public policy.
