Nobody alive today signed anything that put a government in charge of them. No ballot anyone cast created the laws about contracts, property, or violence that bind them anyway. And yet most people, most of the time, treat the state’s authority as legitimate rather than as an armed stranger’s demand. Social contract theory is the few-hundred-year-old attempt to explain why that’s reasonable — by imagining that political authority rests on an agreement, real or hypothetical, that free and equal people would make with each other. It’s one of the most influential ideas in the history of political thought, and it’s also been argued over, revised, and attacked by its own tradition’s descendants for just as long. (For the short version, see our Explainer What Is the Social Contract? This piece goes deeper, into the theory’s internal disagreements and its sharpest modern critiques.)
What Did Hobbes Think People Were Like Without Government?
Thomas Hobbes opened the modern version of the argument in Leviathan (1651) with one of philosophy’s bleakest thought experiments: the “state of nature,” a condition with no common power to keep people in order. Hobbes didn’t claim this had literally happened everywhere, but he argued that without an enforced authority, individually rational people pursuing their own survival would inevitably end up in what he called a “war of every man against every man.” His famous description of life in that state is that it would be “solitary, poor, nasty, brutish, and short.”
Hobbes’s solution was stark: people collectively and reciprocally give up their individual right to judge disputes and defend themselves by force, and hand that authority to an absolute sovereign — his “Leviathan” — whose job is simply to keep the peace. In Hobbes’s version, the sovereign isn’t a party to the contract and isn’t bound by it; the whole point is to create a power strong enough that no one can reasonably defy it, because a sovereign who could be second-guessed would just recreate the original problem.
How Did Locke Flip the Script With Natural Rights?
John Locke’s Two Treatises of Government (1689) kept the state-of-nature framework but rejected Hobbes’s grim picture of it. For Locke, the state of nature isn’t lawless chaos; it’s “pre-political” but not “pre-moral” — people already have natural rights to life, liberty, and property, and a natural law that obligates them to respect those rights in others, even with no government around to enforce it. The practical problem isn’t that people are naturally violent; it’s that without an impartial judge, disputes over those rights are hard to resolve fairly, and some people will violate them anyway.
So in Locke’s version, people don’t surrender their rights to an unaccountable sovereign — they consent to a government whose entire job is to protect rights they already had. That has a crucial consequence Hobbes’s version doesn’t: if a government betrays that trust and starts violating the rights it was created to protect, Locke argued people retain a right to resist and ultimately replace it. This idea — that legitimate government rests on consent and exists to serve the governed, not the other way around — became one of the direct intellectual roots of the Declaration of Independence more than eighty years later.
Why Did Rousseau Think Civilization Itself Was the Problem?
Jean-Jacques Rousseau took the argument somewhere neither Hobbes nor Locke intended. In The Social Contract (1762), opening with the line “Man was born free, and he is everywhere in chains,” Rousseau argued that humans in a genuine state of nature weren’t vicious or even particularly rights-bearing — they were simply free, and it was the rise of private property and the resulting social inequality that corrupted that natural freedom and created domination of one person over another.
Rousseau’s proposed fix wasn’t to escape the social contract but to redesign it: people should submit not to a king or even to a majority vote as such, but to the “general will” — the collective interest of the community as a whole, which Rousseau thought could genuinely diverge from the sum of individual private interests. His famous, paradoxical-sounding line that people might be “forced to be free” refers to being compelled to follow the general will rather than private impulses that would, in Rousseau’s view, undermine the shared freedom everyone actually wants. Because he thought the general will required a tight, direct relationship between citizens and the laws they lived under, Rousseau believed his model only really worked in small, direct democracies — not sprawling nations.
How Did John Rawls Revive the Idea for the 20th Century?
By the mid-20th century, social contract theory had fallen out of fashion among many philosophers, who treated it mainly as a historical curiosity. John Rawls’s A Theory of Justice (1971) revived it in a strikingly different form: not as a story about an actual historical agreement, and not even fundamentally about consent, but as a thought experiment for figuring out what a fair set of basic social and political rules would look like.
Rawls’s device is the “original position”: imagine a group of people choosing the basic principles that will govern their society, but doing so behind a “veil of ignorance” that hides from them their own race, sex, class, talents, and position in that future society. Not knowing whether you’ll end up rich or poor, advantaged or disadvantaged, Rawls argued, is exactly what would make you choose genuinely fair principles rather than rules rigged in your own favor. From this setup he derived his famous “difference principle”: that social and economic inequalities are justifiable only if they work out to the benefit of society’s least-advantaged members. Rawls’s version doesn’t rest on an actual historical agreement at all — it uses the contract as a purely conceptual tool for defining fairness.
What’s Wrong With the Social Contract?
The theory has drawn serious, persistent criticism from inside and outside the tradition. The oldest objection, raised by the philosopher David Hume, is simply that it’s historical fiction: no such contract was ever actually signed, and even if one’s ancestors had somehow consented to a government, Hume pointed out that their consent doesn’t automatically bind their descendants. Contemporary philosophers like Ronald Dworkin pushed a version of the same worry at hypothetical contracts specifically: an agreement that hypothetical, fully-informed people would make isn’t the same as an agreement anyone actually made, and it isn’t obvious why a hypothetical agreement should be binding on real people who never had the chance to reject it.
A newer and more pointed line of criticism argues the classical social contract wasn’t just incomplete — it was built to exclude people, and that exclusion was the point rather than an oversight. The philosopher Carole Pateman’s The Sexual Contract (1988) argues that the classical social contract tradition assumed and quietly depended on an unmentioned “sexual contract” that subordinated women and excluded them from the public, contracting sphere entirely. Charles Mills’s The Racial Contract (1997) makes a parallel argument about race, contending that the real historical contract among those treated as full persons implicitly excluded non-white people from its protections, functioning as what Mills calls a structure that normalizes racial domination while the official story talks only about universal, abstract consent. Both arguments use the same contractual language the classical theorists did, but to expose who the “everyone” in “everyone would agree” quietly left out.
Contemporary rational-choice versions of the theory, developed most prominently by the philosopher David Gauthier, face a different, more technical problem sometimes called the compliance problem: if morality is just the rules self-interested people would agree to for mutual advantage, what actually stops a self-interested person from breaking the agreement whenever breaking it is personally convenient and they think they won’t get caught? Gauthier spent much of his career trying to show that genuinely rational agents would still constrain themselves even without external enforcement; critics have generally remained unconvinced that self-interest alone can fully explain why anyone should keep a bargain once keeping it stops being useful to them.
Evidence Strength
Well-supported: the textual and historical claims about what Hobbes, Locke, Rousseau, and Rawls actually argued, and the lineage connecting their work (these are matters of documented intellectual history, verifiable in the primary texts and standard reference works like the Stanford Encyclopedia of Philosophy); the direct influence of Locke’s consent-based framework on the American Declaration of Independence.
Contested: whether any version of social contract theory actually succeeds as a justification for political authority and obligation — this remains a live, unresolved debate in political philosophy, not a settled empirical question; whether hypothetical or counterfactual agreements can genuinely bind real people who never consented to anything; and the broader normative question raised by Pateman and Mills, of whether the classical contract tradition’s abstract “everyone” ever included everyone in practice.
Key Takeaways
- Social contract theory holds that political authority and obligation derive from an agreement — actual or hypothetical — among free and equal people.
- Hobbes argued an absolute sovereign is needed to escape a state-of-nature “war of all against all”; Locke argued government exists only to protect natural rights people already have, and can legitimately be resisted if it violates them.
- Rousseau blamed social inequality, not human nature, for domination, and proposed submission to the collective “general will” instead of a sovereign or simple majority rule.
- John Rawls revived the idea in 1971 not as history but as a thought experiment — the “original position” behind a “veil of ignorance” — to work out fair principles of justice, including his influential “difference principle.”
- The classical objection, going back to David Hume, is that no such contract was ever actually signed and that consent can’t simply pass down generations.
- Carole Pateman’s “sexual contract” and Charles Mills’s “racial contract” argue the classical tradition’s supposedly universal agreement was historically built on excluding women and non-white people from its protections.
- Contemporary rational-choice versions of the theory still wrestle with the “compliance problem”: what stops a self-interested party from breaking the agreement once compliance stops serving their interest?
Frequently Asked Questions
Did people actually sign a social contract at some point in history?
No. Even the philosophers who popularized the idea generally didn’t claim it was a literal historical event (Hobbes and Locke used it partly as an explanatory device); Rawls was explicit that his version is a purely hypothetical thought experiment, not history.
What’s the main difference between Hobbes’s and Locke’s social contracts?
Hobbes starts from a violent state of nature and has people surrender their rights to an absolute, unaccountable sovereign to escape it. Locke starts from a state of nature that already has natural rights and moral limits, and has people consent to a government whose job is to protect those rights — a government that can legitimately be resisted if it fails at that job.
What is Rawls’s “veil of ignorance,” in plain terms?
It’s a thought experiment: imagine choosing the basic rules of society without knowing what position — rich, poor, talented, disadvantaged — you yourself will occupy under those rules. Rawls argued that not knowing your own stake would push you toward genuinely fair principles rather than self-serving ones.
What do critics mean by calling the social contract a “sexual contract” or a “racial contract”?
Carole Pateman and Charles Mills argue, respectively, that the classical social contract tradition’s language of universal consent concealed a real historical arrangement that subordinated women and excluded non-white people from full standing — so the “contract among equals” wasn’t actually among everyone, in practice.
Is social contract theory still taken seriously by philosophers today?
Yes, though in heavily revised forms. Rawls’s reinterpretation and later rational-choice versions by philosophers like David Gauthier remain central, actively debated reference points in contemporary political philosophy, even as critics continue to press the historical, feminist, and racial-exclusion objections.
Does the theory assume people must get something concrete in return for obeying the law?
Broadly yes — the core idea across nearly all versions is that political obligation is exchanged for something (security, protection of rights, fair terms of cooperation), which is exactly why critics ask what happens when the state fails to deliver its side of that bargain.
The Bottom Line
Social contract theory isn’t a claim about history — it’s a recurring argument about what would make political authority legitimate in the first place, and the thinkers who built it kept disagreeing about the answer precisely because the stakes are so high. Hobbes thought the alternative to near-absolute authority was chaos; Locke thought unaccountable authority was its own kind of chaos; Rousseau thought the whole premise of private interests needed rethinking; Rawls thought the entire question could be reframed as one of fairness under uncertainty. The theory’s sharpest modern critics, meanwhile, ask a more uncomfortable question: whose consent, exactly, did the “social contract” ever actually ask for? That the argument is still this unsettled, more than 370 years after Hobbes first made it, is less a flaw in the idea than a sign of how hard the underlying question — why should anyone obey anyone else’s rules? — really is.
