Abstract
Readers looking for an articulate, well‐informed exposition of Hayek's multifaceted intellectual achievement will be pleased with Bruce Cald‐well's new book, Hayek's Challenge: An Intellectual Biography of F. A. Hayek. Readers interested in a more critical consideration of Hayek's ideas, or in their ability to withstand cross‐examination from the positions Hayek himself criticized, are less likely to be satisfied. But even for the latter group, Caldwell has performed a useful service, compressing the varied elements of Hayek's complex thought into a lucid synopsis that should facilitate engagement with those outside the Austrian camp.
