“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.” (Gene Callahan, Journal of the History of Economic Thought, Vol. 38 (4), December, 2016)
