James A. Sadowsky, S.J., S.T.L. (1923–2012) was professor emeritus of philosophy at Fordham University, where he began teaching in 1960. A convert to Roman Catholicism from Anglicanism (1939) and ordained as a priest of the Society of Jesus (1957), he was a friend of Murray Rothbard's since the early 1960s and a Rothbardian in political philosophy and economics. Rothbard endorsed Sadowsky’s definition of rights (as formulated in the latter's 1966 article, "Private Property and Collective Ownership," which Rothbard cites in his The Ethics of Liberty (1982).
Ludwig von Mises: "Despots and democratic majorities are drunk with power. They must reluctantly admit that they are subject to the laws of nature. But they reject the very notion of economic law . . . economic history is a long record of government policies that failed because they were designed with a bold disregard for the laws of economics." - Austrian Economics: An Anthology
