Abstract
William Dwyer reviews Initiative: Human Agency and Society, in which Tibor Machan argues that free will is a prerequisite for knowledge, ethics, and political liberty. Machan criticizes Hayek, Stigler, and "public choice" economics for their economic determinism and for discounting the importance of abstract ideas. Despite making a good case against environmental and economic determinism, Machan fails adequately to defend his central thesis that free will exists and that it is required for normative values
