Robert Nozick (November 16, 1938 – January 23, 2002) was an American political philosopher, most prominent in the 1970s and 1980s. He was a professor at Harvard University. He is best known for his book Anarchy, State, and Utopia (1974), a right-libertarian answer to John Rawls's A Theory of Justice (1971). His other work involved decision theory and epistemology.


Personal life

Nozick was born in Brooklyn, the son of a Jewish entrepreneur from the Russian shtetl who had been born with the name of Cohen.[2] Nozick was married to the poet Gjertrud Schnackenberg. He died in 2002 after a prolonged struggle with stomach cancer. He is interred at Mount Auburn Cemetery in Cambridge, Massachusetts.

Career and works

Nozick was educated at Columbia (A.B. 1959, summa cum laude), where he studied with Sidney Morgenbesser, and later at Princeton (Ph.D. 1963), and Oxford as a Fulbright Scholar.

Nozick's Anarchy, State, and Utopia (1974), which received a National Book Award, argues among other things that a distribution of goods is just if brought about by free exchange among consenting adults and from a just starting position, even if large inequalities subsequently emerge from the process. Nozick appealed to the Kantian idea that people should be treated as ends (what he termed 'separateness of persons'), not merely as a means to some other end. Nozick here challenges the partial conclusion of John Rawls's Second Principle of Justice of his A Theory of Justice, that "social and economic inequalities are to be arranged so that they are to be of greatest benefit to the least-advantaged members of society." Anarchy, State and Utopia claims a heritage from John Locke's Second Treatise on Government and tries to base itself upon a natural law doctrine. Locke only relied on natural law as God-given to counteract the King of England's claim to divine right and thus claim to all the property of England. Nozick suggested, again as a critique of utilitarianism, that the sacrosanctity of life made property rights non-negotiable, as an individual's personal liberty was taken to be more valuable than the state's policies of redistribution. This principle has served as a foundation for many right-libertarian pitches into modern politics. Most controversially, Nozick argued that a consistent upholding of the non-aggression principle would allow and regard as valid consensual/non-coercive enslavement contracts between adults. He rejected the notion of inalienable rights advanced by most other capitalist-oriented libertarian academics, writing in Anarchy, State and Utopia that the typical notion of a "free system" would allow adults to voluntarily enter into non-coercive slave contracts.[1][3][4][5][6][7][8][9][10][11][12][13][14]


In Philosophical Explanations (1981), which received the Phi Beta Kappa Society's Ralph Waldo Emerson Award, Nozick provided novel accounts of knowledge, free will, personal identity, the nature of value, and the meaning of life. He also put forward an epistemological system which attempted to deal with both the Gettier problem and those posed by skepticism. This highly influential argument eschewed justification as a necessary requirement for knowledge.[15]

Nozick's Four Conditions for S's knowing that P were:

  1. P is true
  2. S believes that P
  3. If it were the case that (not-P), S would not believe that P
  4. If it were the case that P, S would believe that P

Nozick's third and fourth conditions are counterfactuals. Nozick calls his theory the "tracking theory" of knowledge. Nozick believes that the counterfactual conditionals bring out an important aspect of our intuitive grasp of knowledge: For any given fact, the believer's method must reliably track the truth despite varying relevant conditions. In this way, Nozick's theory is similar to reliabilism. Due to certain counterexamples that could otherwise be raised against these counterfactual conditions, Nozick specified that:

  1. If P weren’t the case and S were to use M to arrive at a belief whether or not P, then S wouldn’t believe, via M, that P.
  2. If P were the case and S were to use M to arrive at a belief whether or not P, then S would believe, via M, that P.[16]

Where M stands for the method by which S came to arrive at a belief whether or not P.

Later books

The Examined Life (1989), pitched to a broader public, explores love, death, faith, reality, and the meaning of life. According to Stephen Metcalf, in the chapter The Zigzag of Politics, Nozick expresses serious misgivings about capitalist libertarianism, going so far as to reject much of the foundations of the theory on the grounds that personal freedom can sometimes only be fully actualized via a collectivist politics and that wealth is at times justly redistributed via taxation to save an overly selfish minority from itself.[17] This statement by Metcalf regarding Nozick's misgivings however is contested, as an interview with Nozick illustrates.[18] To temper this argument, he suggests that citizens opposed to wealth redistribution that fund programs they object to should be able to opt out by supporting alternative government approved charities with an added 5% surcharge. The Nature of Rationality (1993) presents a theory of practical reason that attempts to embellish notoriously spartan classical decision theory. Socratic Puzzles (1997) is a collection of papers that range in topic from Ayn Rand and Austrian economics to animal rights, while his last production, Invariances (2001), applies insights from physics and biology to questions of objectivity in such areas as the nature of necessity and moral value.


Nozick created the thought experiment of the "utility monster" to show that average utilitarianism could lead to a situation where the needs of the vast majority were sacrificed for one individual. He also devised the thought experiment of The Experience Machine in an attempt to show that ethical hedonism was false. Nozick asked us to imagine that "superduper neuropsychologists" have figured out a way to stimulate a person's brain to induce pleasurable experiences.[19] We would not be able to tell that these experiences were not real. He asks us, if we were given the choice, would we choose a machine-induced experience of a wonderful life over real life? Nozick says no, then asks whether we have reasons not to plug into the machine and concludes that since it does not seem to be rational to plug in, ethical hedonism must be false.

Unusual method

Nozick was notable for the exploratory style of his philosophizing and for his methodological ecumenism. Often content to raise tantalizing philosophical possibilities and then leave judgment to the reader, Nozick was also notable for drawing from literature outside of philosophy (e.g., economics, physics, evolutionary biology).
