Book excerpt: Friedrich Hayek was the 20th century’s most significant free market theorist. Over the course of his long career he developed an analysis of the danger that state power can pose to individual liberty. In rejecting much of the liberal tradition’s concern for social justice and democratic participation, Hayek would help clear away many intellectual obstacles to the emergence of neoliberalism in the last quarter of the 20th century. At the core of this book is a new interpretation of Hayek, one that regards him as an exponent of a neo-Roman conception of liberty and interprets his work as a form of ‘market republicanism’. It examines the contemporary context in which Hayek wrote, and places his writing in the long republican intellectual tradition. Hayek’s Market Republicanism will be of interest to advanced students and researchers across the history of economic thought, the history of political thought, political economy and political philosophy.
