The book outlines and explains the work of the Nobel economist and social theorist Friedrich Hayek. Hayek was one of the leading economists of the 20th century, and the leading contemporary critic of Keynes. He did pioneering work on monetary theory and trade cycles, but achieved international fame through his 1944 critique of totalitarian socialism, "The Road to Serfdom". He went on to map out the principles of a free society in a series of books including "Law, Legislation and Liberty" and became the leading proponent, along with Milton Friedman, of economic and political liberalism. This book incorporates some of the criticisms that have been made of Hayek since his death and will be able to place him more securely in the context of current liberal thought.
