This book presents the theoretical and practical arguments for liberalism in the classical tradition as defined by Mises as ?the liberal doctrine of the harmony of the rightly understood interests of all members of a free society founded on the principle of private ownership of the means of production.? The foundation of liberalism, Mises says, rests on an understanding and appreciation of private property, social cooperation, the freedom idea, ethics and morality, democracy, and the legitimate role of government. 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.Bettina Bien Greaves is a former resident scholar and trustee of the Foundation for Economic Education and was a senior staff member at FEE from 1951 to 1999.
