La acción humana
Theory and History: An Interpretation of Social and Economic Evolution is a treatise by Austrian school economist and philosopher Ludwig von Mises. It can be thought of as a continuation in the development of the Misesian system of social science. In particular, it provides further epistemological support for his earlier works, esp. Human Action. Most notably, Mises elaborates on methodological dualism, develops the concept of thymology – a historical branch of the sciences of human action – and presents his critique of Marxist materialism.
