Nozick's Tale of the Slave

At what point in a sequence of liberalisations does slavery end?

Robert Nozick · 1974 · Political philosophy

First published: R. Nozick, *Anarchy, State, and Utopia* (1974), 290–292.

A slave's situation is liberalised step by step until he is a citizen voting for his own laws. Is he still a slave? If not, when did he stop being one?

Nozick presents nine stages of progressive liberalisation of a slave's condition: from a brutal master, to a kind one, to a master controlled by a council, to a council including the slave's vote, to a council in which the slave votes only when there is a tie, to one where his vote is the deciding one if it changes the outcome. At each step, conditions improve; at the final step, the "slave" is in the position of every citizen in a democracy. The case is a sharp libertarian provocation: either majoritarian democracy contains a residual element of coercion analogous to slavery, or there is a clean cut-off the sequence reveals as arbitrary.

Formulation

Stage 1: slave to brutal master. Stages 2–8: progressive liberalisations. Stage 9: subject of democratic state with full vote. Question: at which step does slavery end? Nozick: if never, democracy contains slavery; if at some step, the cut-off is morally hard to defend.

Responses — How Schools Engage

Denies / rejects the premise 1

Liberation Theology

The case obscures the structural difference between exploitative property relations and democratic coordination; the slippery slope to "democracy = slavery" is libertarian sleight of hand.

Reframes the question 5

Naturalism

Libertarian naturalism: the case discloses that all coerced political arrangements contain elements that cannot be sharply distinguished from slavery. The lesson is to minimise coercion.

Pragmatism

The slavery / legitimate-authority distinction is not a sharp line but tracks features of practice: voice, exit, consent, fairness of process. Nozick's puzzle is a useful provocation, not a knock-down.

Kantian Transcendental Idealism

A legitimate state respects the autonomy of rational agents; democratic participation is one institutional realisation of this respect. Slavery is principled deprivation of autonomy, not merely a degree of coercion.

Existentialism

Authentic freedom is not exhausted by political structure; both the slave and the citizen face the existential task of taking up their freedom. Nozick targets a different question.

Reformed / Calvinist Theology

Political authority is divinely instituted but bounded by moral law; slavery is intrinsically wrong, legitimate authority is not, and a careful theology resists the conflation.
