Justice and the Social Contract (SACE Stage 2 Philosophy)

Syllabus dot point

“Evaluate social contract theories and competing conceptions of distributive justice”

7 min read

Quick answer

Political philosophy asks what justifies the state's authority over us and what counts as a just society. Social contract theory argues that legitimate authority rests on the agreement of the governed, developed differently by Hobbes, Locke and Rousseau, and revived by Rawls. On distributive justice, Rawls defends fairness through the original position, Nozick defends entitlement and the minimal state, and communitarians question the abstract individual both assume. You should evaluate these views.

What this dot point is asking

You need to explain social contract theory, set out rival theories of distributive justice, and assess their strengths and objections.

The social contract tradition

Social contract theory grounds political authority in the consent of the governed. Thomas Hobbes, in Leviathan, imagined a state of nature without government as a war of all against all, where life is poor, nasty, brutish and short. To escape it, rational individuals agree to surrender their freedom to an absolute sovereign who keeps the peace. John Locke offered a gentler picture: in the state of nature people have natural rights to life, liberty and property, and they form government to protect those rights, retaining a right of revolution if the government betrays its trust. Jean-Jacques Rousseau argued that legitimate authority expresses the general will, the collective interest of a free people, so that we obey only ourselves.

The strength of contract theory is that it makes authority answerable to the governed rather than to tradition or force. The main objection, pressed by David Hume, is that the contract is a fiction, since no one actually signed it, and tacit consent through residence is weak, given that most people cannot realistically leave.

Rawls and justice as fairness

John Rawls revived the contract idea as a device for testing principles of justice. He asks what principles people would choose behind a veil of ignorance, in an original position where they do not know their place in society, their talents or their wealth. Reasoning impartially, he argues, they would choose two principles: first, equal basic liberties for all; second, the difference principle, allowing inequalities only if they benefit the least advantaged. The appeal is that it models fairness by stripping away self-interested bias. Critics object that rational agents might not be so risk-averse, and that the veil produces an unrealistically abstract chooser.

Nozick and the entitlement theory

Robert Nozick, in Anarchy, State and Utopia, challenged Rawls from a libertarian direction. Justice, he argued, is about how holdings are acquired and transferred, not about their final pattern. If property is justly acquired and justly transferred, the resulting distribution is just however unequal. His Wilt Chamberlain example argues that any preferred pattern of distribution will be upset by free voluntary exchanges, so enforcing a pattern requires continual interference with liberty. Nozick therefore defends only a minimal night-watchman state. The objection is that initial acquisitions are often historically unjust, and that the view tolerates extreme inequality and offers little to those born into disadvantage.

Communitarian critique

Communitarians such as Michael Sandel and Alasdair MacIntyre question the abstract, unencumbered individual that both Rawls and Nozick presuppose. Real people, they argue, are constituted by communities, traditions and shared goods, and justice cannot be derived from individuals imagined apart from these attachments. This restores attention to community and the common good, but critics worry it can slide into relativism or endorse oppressive traditions.

Evaluating

A strong answer weighs the trade-off between liberty and equality that runs through the debate. Contract theory powerfully grounds authority in consent yet rests on a fiction. Rawls secures fairness for the worst off but at some cost to liberty and realism. Nozick protects liberty but tolerates harsh inequality. Communitarians correct the abstraction of both but risk endorsing the status quo. The most defensible position is likely a reflective balance that takes both liberty and the claims of the disadvantaged seriously.

The veil of ignorance models impartiality

Rawls argues that fair principles are those we would choose without knowing our own place in society. By stripping away knowledge of our talents and wealth, the original position forces us to reason impartially, which is the core idea of justice as fairness.

Evaluating the social contract in an essay

The marks come from grounding authority in consent then testing it. Work it in steps.

Step 1: state the consent thesis

Set out that legitimate authority rests on the agreement of the governed, the shared core from Hobbes to Rawls.

Step 2: contrast the classic versions

Distinguish Hobbes (security via an absolute sovereign), Locke (rights and revolution) and Rousseau (the general will).

Step 3: press the fiction objection

Apply Hume that no one signed the contract and tacit consent is weak when leaving is unrealistic.

Step 4: assess the hypothetical revival and conclude

Show Rawls reframes the contract as a test of fair principles, then defend whether consent can ground authority. The consent thesis tested against the fiction objection and a defended verdict is what the top band rewards.

Common errors
Treating the social contract as a real historical event
It is a hypothetical device for justifying authority, not a claim that people once literally signed an agreement.
Confusing Rawls and Nozick
Rawls cares about the pattern of distribution and the least advantaged; Nozick cares only about just acquisition and transfer, regardless of the resulting pattern.
Equating equality with justice automatically
Each theory argues for its conception; a Stage 2 answer must defend, not assume, what justice requires.

Practice15 marks
"Political authority is legitimate only if it rests on consent." Critically discuss social contract theory.
Show worked answer →

A 15 mark essay needs the tradition, the consent objection and a defended conclusion.

Set out the tradition. Hobbes's war of all against all and absolute sovereign, Locke's natural rights and right of revolution, Rousseau's general will.

Give the strength. Authority is answerable to the governed, not tradition or force.

Object. Press Hume that the contract is a fiction no one signed and tacit consent is weak when leaving is unrealistic.

Conclude. Defend whether consent, hypothetical or actual, can ground authority. Markers reward the contract-as-fiction objection and a defended thesis.

Practice12 marks
Evaluate Rawls's use of the original position to derive principles of justice.

A 12 mark essay needs the device explained, its output and a judgement.

Explain it. Behind the veil of ignorance, not knowing one's place, talents or wealth, people reason impartially and choose equal liberties and the difference principle.

Give its appeal. It models fairness by removing self-interested bias.

Object. Press that rational agents may not be so risk-averse and that the chooser is unrealistically abstract.

Judge. Conclude how far the original position justifies its principles. Markers reward the maximin and abstraction objections engaged and a defended verdict.
