Wilhelm Röpke (1899–1966) was schooled in the tradition of the Austrians and made enormous contributions to the study of political institutions. His powerful anti-Keynesian writings in particular underscore what an outstanding economist he was and the extent to which he was influenced by Mises. Röpke defended sound money and free trade, and attacked welfare. While some consider him a doubter on free markets, he was in fact a passionate advocate of laissez-faire.
Ludwig von Mises: "In Nature too, much may exist that we do not like. But we cannot change the essential character of natural events. If, for example, someone thinks — and there are some who have maintained as much — that the way in which man ingests his food, digests it, and incorporates it into his body is disgusting, one cannot argue the point with him. One must say to him: There is only this way or starvation." - Liberalism
