 Robert Nozick was born in Brooklyn in 1938 to a Russian Jewish immigrant family. He earned an undergraduate Philosophy degree from Columbia University in 1959 and a Ph.D. in Philosophy from Princeton University in 1963. He taught for a couple of years at Princeton, Harvard, and Rockefeller Universities before moving permanently to Harvard in 1969. He became widely known through his 1974 book, Anarchy, State, and Utopia, which shocked the philosophical world with its robust and sophisticated defense of the minimal state—the state that restricts its activities to the protection of individual rights of life, liberty, property, and contract and eschews the use of state power to redistribute income, to make people moral, or to protect people from harming themselves. Nozick went on to publish important works that ranged over metaphysics, epistemology, the philosophy of science, and axiology—Philosophical Explanations (1981), The Examined Life (1989), The Nature of Rationality (1993), Socratic Puzzles (1997), and Invariances (2001). Nozick’s always lively, engaging, audacious, and philosophically ambitious writings revealed an amazing knowledge of advanced work in many disciplines including decision theory, economics, mathematics, physics, psychology, and religion. Robert Nozick died in 2002 from stomach cancer for which he was first treated in 1994.
