Franz Oppenheimer (1864–1943) was a German-Jewish sociologist and political economist, best known for his work on the fundamental sociology of the state. His book The State: Its History and Development Viewed Sociologically was the prototype for Albert Jay Nock's writing, for Frank Chodorov's work, and even for the theoretical edifice that later became Rothbardianism.
Ludwig von Mises: "There is no such thing as an absolute notion of justice not referring to a definite system of social organization. . . . There is neither right nor wrong outside the social nexus." - Human Action
