The Encounter That Defined an Era
In 1971, John Rawls (1921–2002) published A Theory of Justice — a work that revived normative political philosophy after decades of positivist dominance. Three years later, in 1974, Robert Nozick (1938–2002) responded with Anarchy, State, and Utopia, which became the most rigorous libertarian critique of the Rawlsian program. Both were professors at Harvard. The debate they conducted — personally amicable, philosophically radical — remains the most productive confrontation in twentieth-century Anglo-American political philosophy.
Rawls: Justice as Fairness
The Original Position and the Veil of Ignorance
Rawls’s problem: how to establish principles of justice that are genuinely impartial? His solution is a thought experiment: imagine that people choose principles of justice from an original position, behind a veil of ignorance — without knowing what position they will occupy in society (class, sex, race, natural talents, conception of the good, generation).
No one would choose principles that favor specific groups if they did not know which group they belong to. This strategic ignorance guarantees impartiality.
The Two Principles
From the original position, Rawls derives two lexicographically ordered principles:
First Principle — Equal Basic Liberties: Each person should have an adequate system of equal basic liberties (political liberty, freedom of expression and conscience, personal property, freedom from arbitrary arrest).
Second Principle: Social and economic inequalities must be arranged so that they:
- (a) provide the greatest benefit to the least advantaged members of society (the difference principle);
- (b) are attached to offices and positions open to everyone under conditions of fair equality of opportunity.
The difference principle is the most controversial: inequalities are justified only if they benefit the worst-off. This is not radical egalitarianism (it does not require strict equality) but it demands that the system be designed in favor of those at the bottom.
Political, Not Metaphysical
In Political Liberalism (1993), Rawls revised his theory: “justice as fairness” is not a comprehensive philosophical doctrine but a political module that can be the object of an overlapping consensus among citizens with diverse worldviews. The liberal state does not impose a conception of the good life.
Nozick: Rights, the Minimal State, and Entitlement
The Fundamental Critique
Nozick begins with a premise that Rawls does not sufficiently question: people have rights that are “side constraints” — not factors to be maximized, but limits that cannot be violated for any cause, including improving the situation of the least advantaged.
Rawls’s assumption, according to Nozick, is that society’s distribution is like a pie that needs to be justly divided. But this assumption ignores that resources already belong to someone — they are the result of real people’s actions, labor, and exchanges. There is no “neutral” distribution to be corrected: there are only histories of acquisitions and transfers.
The Entitlement Theory
A distribution is just if it results from:
- Just acquisition: original appropriation of unowned resources in a way that does not worsen others’ situation
- Just transfer: voluntary exchange, gift, bequest
- Rectification: correction of historical injustices
Any distribution resulting from a chain of just acquisitions and transfers is just — regardless of the resulting pattern.
The Wilt Chamberlain Argument
To show that pattern-based distribution principles are incompatible with liberty, Nozick invokes an example: suppose distribution D1 is agreed to be just (egalitarian or conforming to the difference principle). Now, one million people, each freely, give Wilt Chamberlain twenty-five cents to watch him play basketball. D2 results, in which Wilt has $250,000 more than anyone else. Is D2 unjust? But every transaction was voluntary; no right was violated. Imposing a redistribution principle to correct D2 would require continuous interference with voluntary exchanges — which is incompatible with liberty.
Conclusion: Liberty upsets patterns. Maintaining patterns requires continuous coercion.
The Minimal State
The only justifiable state is the minimal state — limited to protection against violence, theft, and fraud, and to enforcement of contracts. Any more extensive state that redistributes wealth violates individual rights without consent — it is equivalent to forced labor (taking part of someone’s labor product to give to another).
The Debate: What Is at Stake
| Issue | Rawls | Nozick |
|---|---|---|
| Nature of justice | Fair pattern | History of entitlements |
| Role of the state | Redistributive liberal state | Minimal state |
| Redistributive taxation | Just, if benefits the worst-off | Equivalent to forced labor |
| Foundation | Original position / veil of ignorance | Natural individual rights |
| Priority | Basic liberties + difference | Negative liberty |
Critiques of Both
Communitarians (Sandel, MacIntyre, Taylor): Rawls presupposes an “unencumbered self” without identity, tradition, or pre-political common good — a philosophical fiction that distorts human nature. Michael Sandel, in Liberalism and the Limits of Justice (1982), argues that the veil of ignorance is not merely a heuristic but presupposes that the self is prior to its ends — which contradicts how people actually form identities.
Feminists (Okin, Pateman): Susan Moller Okin (Justice, Gender, and the Family, 1989) notes that Rawls does not apply the difference principle to the family structure — where gender inequalities are most deeply entrenched.
Critique of Nozick: The theory of just original acquisition is implausible — the actual history of property is full of violence, colonization, and theft. The “rectification” Nozick admits would be so massive as to undo the current system entirely.
Conclusion
The Rawls-Nozick debate did not end — it proved fertile for subsequent generations. It revealed that invoking liberty or equality is not enough: one must specify which liberty, equality of what, and for whom.
