The Social Contract

Chapter-by-chapter summary

The book has four short parts, called books. Book I sets out the basic principle, Book II deals with sovereignty and law, Book III with government, and Book IV with practical institutions.

Part 1: Book I, Why Free People Obey (chapters 1–9)

Rousseau opens with the problem: people are born free but are everywhere in chains. He then rejects the usual excuses for power. Might does not make right, because force only works while it lasts. Slavery cannot be legitimate, since no one can truly give away their own freedom. The solution is the social compact: each person hands all rights to the community, and so no one is above anyone else. The result is a body with a will of its own, the sovereign, and citizens gain civil freedom and property rights in return. This matters because it makes consent, not strength or birth, the only basis of authority.

Part 2: Book II, chapters 1–5, Sovereignty and the General Will

Sovereignty, Rousseau says, is the exercise of the general will, so it cannot be handed over or split up. A people can delegate tasks, but not its right to decide. The general will aims at the common good. It is not the same as the “will of all”, which only adds up private wishes. Rousseau admits that people can be misled: the general will is always right in aim, but a people's debates are not always correct. The sovereign may ask citizens to accept limits only when they bind everyone equally and serve the public. This matters because it sets the test for every law: does it serve all citizens alike?

Part 3: Book II, chapters 6–12, Law, the Legislator and the People

Laws are acts of the general will applied to the whole community, never to one named person. Rousseau says a nation needs a wise founder, the legislator, who shapes its basic laws without ruling it. He also warns that a people must be ready for a given set of laws: size, climate, customs and age all matter. The aims of a good legal system, he says, are freedom and equality, and he wants no citizen rich enough to buy another or poor enough to be forced to sell himself. This matters because Rousseau treats equality as the condition that keeps freedom from turning into privilege for a few.

Part 4: Book III, Government and Its Dangers (chapters 1–18)

Here Rousseau separates the sovereign, which is the people, from the government, the officials who carry out its laws. Governments can be run by one person, a few or many, and each form suits different countries. Government always tends to grow stronger against the sovereign, so it slowly wears the state down. He argues that the people should not give up lawmaking to representatives, and he mocks the English for thinking they are free outside election time. Regular public assemblies are his remedy. This matters because the book explains why Rousseau trusted direct participation more than parliaments.

Part 5: Book IV, chapters 1–5, Voting, Elections and Roman Examples

Rousseau argues that when citizens are honest and simple, the general will is easy to see, and decisions come close to unanimous agreement. Majority voting works only because the first contract itself was unanimous, and the closer a vote comes to unanimity, the safer the decision is. Drawing on the Roman assemblies, he then asks how voting and elections can work in practice, and he describes the tribunate as a guardian of the balance between people and government. This matters because it shows him trying to turn abstract theory into real procedures, the most practical stretch of the book.

Part 6: Book IV, chapters 6–9, Emergency Rule, Censorship and Civil Religion

The final chapters cover special tools. A temporary dictatorship may protect a state in a crisis, as it did in Rome, but only for a short, fixed time. Censorship keeps public opinion in line with shared values. The last major chapter proposes a civil religion: a short list of public beliefs set by the state, such as the sanctity of the social contract and the laws, with tolerance for other faiths that do not clash with civic duty. Citizens who reject these beliefs could be banished. Critics see this as a threat to liberty, and the religious chapter helped draw the condemnation the book met when it appeared. This matters because it shows the tension between shared loyalty and freedom of conscience that runs through the whole book.

Key people and terms

• General will: the shared interest of the whole community, as opposed to what any person or group wants for itself. Rousseau says laws are legitimate only when they express it. It is a standard for judging decisions, not simply the result of a headcount.
• Sovereign: the people as a whole acting as lawmaker. In Rousseau's theory, final authority belongs to the sovereign, not to a king or a parliament, and it can be neither given away nor divided.
• Social contract: the agreement by which individuals join together into a political community. Each gives up personal power to the group and receives equal rights as a citizen. Rousseau treats it as a test for legitimate authority, not as a historical event.
• Will of all: the sum of private wishes. Rousseau separates it from the general will: if everyone votes for personal gain, the total may point in a direction that helps nobody in common.
• Natural and civil freedom: natural freedom is doing whatever one can, limited only by strength. Civil freedom is living under laws one has helped make. Rousseau argues the second is worth more because it is secure and equal.
• Legislator: a wise founder who drafts a nation's laws but holds no power to enforce them. Ordinary people may miss their long-term interest, so a guide helps, but only the people can approve the laws.
• Government: the body of officials who carry out the sovereign's laws. Rousseau sees it as a servant of the people that tends to grow stronger over time and must therefore be watched.
• Civil religion: a short set of public beliefs that Rousseau thinks citizens must accept to be loyal, including respect for the contract and the laws. Critics see it as a limit on freedom of conscience.
• Hobbes, Locke and Montesquieu: Rousseau's main predecessors. Thomas Hobbes (Leviathan, 1651) argued for a strong sovereign, John Locke (Two Treatises, 1689) for rights and limited government, and Montesquieu (The Spirit of the Laws, 1748) for separated powers. Rousseau places sovereignty in the people themselves.

Writing about this book

The Social Contract works well for essays, class discussions and exam answers when you write about one question rather than the whole book. Pick a question, point to a specific book and chapter, and then give your own view with reasons.

• Is a school or club rule closer to the general will, or just to what the majority wants?
• Can obeying a law you helped make really be called freedom? When does it feel that way, and when not?
• Rousseau thinks large gaps in wealth threaten liberty. How would you test that idea today?
• What are the strengths and weaknesses of voting directly compared with electing representatives?
• Should a state ask citizens to share a civic creed, as the civil religion chapter suggests?

Comparing Rousseau with Hobbes or Locke makes an argument stronger. Separate what you accept from what you doubt; that is more convincing than simply agreeing or disagreeing.
