This is an intellectual biography of G.L.S. Shackle, economic theorist, philosopher, and historian of economic theory. It explores how Shackle challenged the aims, methods and assumptions of mainstream economics. He stressed macroeconomic instability, and developed a radically subjectivist theory for behavioural economics and business planning.
"This intellectual history of the English economist George Lennox Sharman Shackle is part of the Great Thinkers in Economics series. ... this book provides a very good introduction to Shackle's central concern-his theory of choice under uncertainty-and provides an excellent starting point for anyone wishing to become familiar with this important heterodox thinker."
