PERSON
Robert Nozick
Harvard political philosopher (1938–2002) whose 1974 Anarchy, State, and Utopia mounted the most sustained libertarian challenge to Rawls's theory of justice and became the canonical counterpart to A Theory of Justice in contemporary political philosophy.
Robert Nozick was Rawls's Harvard colleague and his most influential libertarian critic. Anarchy, State, and Utopia, published three years after A Theory of Justice, argued that Rawls's redistributive principles violated individual rights generated through just acquisition and just transfer. Nozick's entitlement theory of justice held that the justice of a distribution depends not on its structural features (whether it benefits the least advantaged, whether it satisfies some patterned conception) but on its history — on whether the holdings that constitute it came to their holders through morally permissible processes. If initial acquisition was just, and if all subsequent transfers were voluntary, the resulting distribution is just regardless of how unequal it happens to be. Nozick's challenge to Rawls continues to structure the libertarian-egalitarian debate in political philosophy, and its application to the AI transition clarifies both the commitments of the Rawlsian framework and the specific claims that libertarian alternatives advance.
