In recent years, the Austrian School has been an influential contributor to the social sciences. Yet most of the attempts to understand this vital school of thought have remained locked into a polemical frame. The Philosophy of the Austrian School challenges this approach through a philosophically grounded account of the School's methodological, political, and economic ideas. Raimondo Cubeddu acknowledges important differences between the key figures in the School--Menger, Mises and Hayek-- but also finds important parallels between these thinkers. The theory of subjective value and the theory of spontaneous order, which both rest on ideas about the limitations of human knowledge, are the most important of these parallels. Drawn together, these theories represent one of the most original avenues of research in the social sciences and a major reformulation of liberal ideology.
