Robert Nozick (/ˈnoʊzɪk/; November 16, 1938 – January 23, 2002) was an American philosopher. He held the Joseph Pellegrino University Professorship at Harvard University,[3] and was president of the American Philosophical Association. He is best known for his books Anarchy, State, and Utopia (1974), a libertarian answer to John Rawls' A Theory of Justice (1971), in which Nozick also presented his own theory of utopia as one in which people can freely choose the rules of the society they enter into. His later work, Philosophical Explanations (1981), advanced notable epistemological claims, namely his counterfactual theory of knowledge.

Nozick's other work involved ethics, decision theory, philosophy of mind, metaphysics and epistemology. His final work before his death, Invariances (2001), introduced his theory of evolutionary cosmology, by which he argues invariances, and hence objectivity itself, emerged through evolution across possible worlds.[4]

Personal life

Nozick was born in Brooklyn to a family of Jewish descent. His mother was born Sophie Cohen, and his father was a Jew from a Russian shtetl who had been born with the name Cohen and who ran a small business.[5]

Nozick attended the public schools in Brooklyn. He was then educated at Columbia College, Columbia University (A.B. 1959, summa cum laude), where he studied with Sidney Morgenbesser; Princeton University (PhD 1963) under Carl Hempel; and at Oxford University as a Fulbright Scholar (1963–1964).

At one point, Nozick joined the Young People’s Socialist League, and at Columbia University he founded the local chapter of the Student League for Industrial Democracy. He began to move away from socialist ideals when exposed to Friedrich Hayek's The Constitution of Liberty, claiming he "was pulled into libertarianism reluctantly" when he found himself unable to form satisfactory responses to libertarian arguments.[6]

After receiving his undergraduate degree in 1959, he married Barbara Fierer. They had two children, Emily and David. The Nozicks eventually divorced; Nozick later married the poet Gjertrud Schnackenberg.

Nozick died in 2002 after a prolonged struggle with stomach cancer.[7] He was interred at Mount Auburn Cemetery in Cambridge, Massachusetts.

Career and works

Political philosophy

Nozick’s first book, Anarchy, State, and Utopia (1974), argues that only a minimal state limited to the functions of protection against "force, fraud, theft, and administering courts of law"[8] can be justified, as any more extensive state would violate people's individual rights.

Nozick believed that a distribution of goods is just when brought about by free exchange among consenting adults, trading from a baseline position where the principles of entitlement theory are upheld. In one example, Nozick uses the example of basketball player Wilt Chamberlain to show that even when large inequalities subsequently emerge from the processes of free transfer (i.e. paying extra money just to watch Wilt Chamberlain play), the resulting distributions are just so long as all consenting parties have freely consented to such exchanges.

Anarchy, State, and Utopia is often contrasted to John Rawls's A Theory of Justice in popular academic discourse, as it challenged the partial conclusion of Rawls's difference principle, 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."

Nozick's philosophy also claims a heritage from John Locke's Second Treatise on Government and seeks to ground itself upon a natural law doctrine, but breaks distinctly with Locke on issues of self-ownership by attempting to secularize its claims. Nozick also appealed to the second formulation of Immanuel Kant’s categorical imperative: that people should be treated as an end in themselves, not merely as a means to an end. Nozick terms this the 'separateness of persons', saying that "there are is no social entity...there are only individual people", and that we ought to “respect and take account of the fact that [each individual] is a separate person”.[9]

Most controversially, Nozick argued that consistent application of libertarian self-ownership would allow for consensual, non-coercive enslavement contracts between adults. He rejected the notion of inalienable rights advanced by Locke and most contemporary capitalist-oriented libertarian academics, writing in Anarchy, State, and Utopia that the typical notion of a "free system" would allow individuals to voluntarily enter into non-coercive slave contracts.[10][11][12][13]

Anarchy, State, and Utopia received a National Book Award in the category of Philosophy and Religion in the year following its original publication.[14]

Thought experiments regarding utilitarianism

Early sections of Anarchy, State, and Utopia, akin to the introduction of A Theory of Justice, see Nozick implicitly join Rawls’s attempts to discredit utilitarianism. Nozick’s case differs somewhat in that it mainly targets hedonism and relies on a variety of separate intuition pumps, although both works draw from Kantian principles.

Most famously, Nozick introduced the experience machine in an attempt to show that ethical hedonism is not truly what individuals desire, nor what we ought to desire:

“There are also substantial puzzles when we ask what matters other than how people’s experiences feel “from the inside.” Suppose there were an experience machine that would give you any experience you desired. Superduper neuropsychologists could stimulate your brain so that you would think and feel you were writing a great novel, or making a friend, or reading an interesting book. All the time you would be floating in a tank, with electrodes attached to your brain. Should you plug into this machine for life, preprogramming your life’s experiences?”[15]

Nozick claims that life in an experience machine would have no value, and provides several explanations as to why this might be, including (but not limited to): the want to do certain things, and not just have the experience of doing them; the want to actually become a certain sort of person; and that plugging into an experience machine limits us to a man-made reality.

Another intuition pump Nozick proposes is the utility monster, a thought experiment designed to show that average utilitarianism could lead to a situation where the needs of the vast majority were sacrificed for one individual. In his exploration of deontological ethics and animal rights, Nozick coins the phrase “utilitarianism for animals, Kantianism for people”, wherein the separateness of individual humans is acknowledged but the only moral metric assigned to animals is that of maximising pleasure:

"[Utilitarianism for animals, Kantianism for people] says: (1) maximize the total happiness of all living beings; (2) place stringent side constraints on what one may do to human beings.”[16]

Before introducing the utility monster, Nozick raises a hypothetical scenario where someone might, “by some strange causal connection”, kill 10,000 unowned cows to die painlessly by snapping their fingers, asking whether it would be morally wrong to do so.[17] On the calculus of pleasure that “utilitarianism for animals, Kantianism for people” uses, assuming the death of these cows could be used to provide pleasure for humans in some way, then the (painless) deaths of the cows would be morally permissible as it has no negative impact upon the utilitarian equation.

Nozick later explicitly raises the example of utility monsters to “embarrass [utilitarian theory]": since humans benefit from the mass sacrifice and consumption of animals, and also possess the ability to kill them painlessly (i.e., without any negative effect on the utilitarian calculation of net pleasure), it is permissible humans to maximise their consumption of meat so long as they derive pleasure from it. Nozick takes issue with this as it makes animals “too subordinate” to humans, counter to his view that animals ought to “count for something”[18]a.

Epistemology

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.[19]:ch. 7

Nozick gives four conditions for S's knowing that P (S=Subject / P=Proposition):

  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. He called this the "tracking theory" of knowledge. Nozick believed the counterfactual conditionals bring out an important aspect of our intuitive grasp of knowledge: For any given fact, the believer's method (M) 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.
    3. [20]

A major feature of Nozick's theory of knowledge is his rejection of the principle of deductive closure. This principle states that if S knows X and S knows that X implies Y, then S knows Y. Nozick's truth tracking conditions do not allow for the principle of deductive closure.

Later works

The Examined Life (1989), aimed towards a more general audience, explores themes of love, the impact of death, questions of faith, the nature of reality, and the meaning of life. The book takes its name from the quote by Socrates, that “the unexamined life is not worth living”, and attempts to find meaning in everyday experience, visiting the bonds of love, the values of emotions, and how we might be “more real”.[21] In this pursuit, Nozick discusses the recent death of his father, reappraises the experience machine, and proposes “the matrix of reality” as a means of understanding how individuals might better connect with reality in their own lives.[22]

The Nature of Rationality (1993) presents a theory of practical reason that attempts to embellish classical decision theory. In this work, Nozick grapples with Newcomb's problem and the Prisoner's Dilemma, and introduces the notion that symbolic utility ought to be considered in contemporary analysis of rational action.

Socratic Puzzles (1997) is a collection of Nozick’s previous papers alongside some new essays. While the discussions are quite disparate, the essays generally draw from Nozick's previous interests in both politics and philosophy. Notably, this includes Nozick's 1983 review of The Case for Animal Rights by Tom Regan, where says animal rights activists are often considered “cranks” and appears to go back on the vegetarian position he previously maintained in Anarchy, State and Utopia.[23][24]

Nozick's final work, Invariances (2001), applies insights from physics and biology to questions of objectivity in such areas as the nature of necessity and moral value. Nozick introduces his theory of truth, in which he leans towards a deflationary theory of truth, but argues that objectivity arises through being invariant under various transformations. For example, space-time is a significant objective fact because an interval involving both temporal and spatial separation is invariant, whereas no simpler interval involving only temporal or only spatial separation is invariant under Lorentz transformations. Nozick argues that invariances, and hence objectivity itself, emerged through a theory of evolutionary cosmology across possible worlds.[25]

Later reflections on libertarianism

Nozick pronounced some misgivings about libertarianism - specifically his own work, Anarchy, State and Utopia - in his later publications. Some later editions of The Examined Life advertise this fact explicitly in the blurb, saying Nozick “refutes his earlier claims of libertarianism” in one of the book's essays, “The Zigzag of Politics”. The introduction of The Examined Life mirrors this, with Nozick saying his earlier works on political philosophy “now [seem] seriously inadequate”.[26] In one chapter, “Parents and Children”, Nozick proposes wealth redistribution via an inheritance tax.[27]

Nozick also broke away from libertarian principles in his own personal life, invoking rent control laws against Erich Segal - who was at one point Nozick’s landlord - and winning over $30,000 in a settlement. Nozick later claimed to regret doing this, saying he was moved by “intense irritation” with Segal and his legal representatives at the time, and was quoted in an interview saying “sometimes you have to do what you have to do.”[28]

Some of Nozick’s later works seem to endorse libertarian principles. In Invariances, Nozick advances the “four layers of ethics”, which at its core maintains an explicitly libertarian underpinning.[29] In Socratic Puzzles, Nozick republished some of his old essays with a libertarian grounding, such as "Coercion” and “On The Randian Argument”, alongside new essays such as “On Austrian Methodology” and “Why Do Intellectuals Oppose Capitalism?”. However, Nozick does allude to some continued reservations about libertarianism in its introduction, saying that “it is disconcerting to be known primarily for an early work”.[30]

Scholars and journalists have since debated what Nozick’s true political position was before the end of his life,[31][32] with Julian Sanchez claiming that "Nozick always thought of himself as a libertarian in a broad sense, right up to his final days, even as his views became somewhat less 'hardcore.'"[33]

Philosophical method

Nozick was notable for the exploratory style of his philosophizing. 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).[34]

Popular culture

In the 23rd episode of HBO's show The Sopranos, a eyewitness to one of Tony Soprano's crimes is seen at home reading Anarchy, State, and Utopia, by Robert Nozick. Dani Rodrik uses Bo Rothstein's view to point out that the TV show runners take a position in the debate by how they showed the eyewitness reacting to finding out the man they pointed out as the culprit of the crime he saw was actually the local mafia boss, immediately after the book appears on screen.[35]

Notes

a.^ ^ Nozick's discussion of animal rights pre-dates Peter Singer's more comprehensive Animal Liberation. Singer's utilitarian position on animal rights was known to Nozick at the time, however, and he expresses misgivings about this in Chapter 3 (footnote 11) of Anarchy, State and Utopia.
