Liberalism is not a political party; it is a system of social organization. The liberal program aims at securing equality under law and freedom of opportunity for everyone to make their own choices and decisions, so long as they do not interfere with the equal rights of others; it offers no special privileges to anyone. Under liberalism, the role of government would be limited to protecting the lives, property, and freedom of its citizens to pursue their own ends and goals. Mises is more specific here than elsewhere in applying the liberal program to economic policy, domestic and foreign. Also in this book, Mises contrasts liberalism with other conceivable systems of social organization such as socialism, communism, and fascism.Ludwig von Mises (1881–1973) was the leading spokesman of the Austrian School of Economics throughout most of the twentieth century. He earned his doctorate in law and economics from the University of Vienna in 1906. In 1926, Mises founded the Austrian Institute for Business Cycle Research. From 1909 to 1934, he was an economist for the Vienna Chamber of Commerce. Before the Anschluss, in 1934 Mises left for Geneva, where he was a professor at the Graduate Institute of International Studies until 1940, when he emigrated to New York City. From 1948 to 1969, he was a visiting professor at New York University.Bettina Bien Greaves is a former resident scholar, trustee, and longtime staff member of the Foundation for Economic Education.

A student of Mises, Greaves has become an expert on his work in particular and that of the Austrian School of economics in general. She has translated several Mises monographs, compiled an annotated bibliography of his work, and edited collections of papers by Mises and other members of the Austrian School.
