As Hayek's ideas matured, he became increasingly critical of developments within mainstream economics; his works evolved in striking—and sometimes seemingly contradictory—ways. Caldwell is ideally suited to explain the complex evolution of Hayek's thought, and his analysis here is nothing short of brilliant, impressively situating Hayek in a broader intellectual context, unpacking the often difficult turns in his thinking, and showing how his economic ideas came to inform his ideas on the other social sciences. Hayek is fortunate in his biographer. Hayek's Challenge is a success, and Caldwell proves himself capable of presenting Hayek's ideas—in all fields—with both depth and clarity.
