A major work by the Austrian libertarian philosopher and economist Ludwig von Mises, originally published in America the previous year.
Theory and History is “a sweeping epistemological vindication of the case for liberty and capitalism. Mises argued that the only scientific interpretation of social reality was based on economics and history, and that the conclusions of both these disciplines led to the more speculative of utilitarian philosophy as he understood it. He showed the major alternative approaches - Marxism, positivism, and historicism - despite their pretension to science, were untenable on epistemological grounds” (Hulsmann, Mises: The Last Knight of Liberalism, pp. 949-50).
