Morris and Linda Tannehill were two libertarian activists and thinkers who, in the early 1970s, made surprisingly profound advances in the theory of the stateless society.

Ludwig von Mises: "Only stilted pedants can conceive the idea that there are absolute norms to tell what is beautiful and what is not. They try to derive from the works of the past a code of rules with which, as they fancy, the writers and artists of the future should comply. But the genius does not cooperate with the pundit." - Theory and History
