The Social Contract

Summary

Of the Social Contract, or Principles of Political Right is a compact treatise in four books, the only finished part of a larger work on political institutions that Rousseau abandoned. It opens with its most famous sentence, that man is born free and everywhere in chains, and with a promise not to explain how this happened but to say what could make it legitimate. Book I clears away false foundations. The family is the only natural society, and even it lasts only while children need their father. Force cannot create right, since yielding to force is necessity, not duty. Slavery, whether of individuals or of conquered peoples, is void, because no one can give himself away for nothing and a promise of absolute obedience is meaningless. Rousseau then states the problem: to find a form of association that defends each member with the whole common force while leaving each as free as before. The answer is the social compact, in which each person gives himself and all his rights to the whole community. Because the condition is equal for all, no one has an interest in making it burdensome, and the act creates a public person, the sovereign, whose will is the general will. Whoever refuses to obey it will be forced to be free. The passage to the civil state replaces instinct with justice and turns a stupid, limited animal into a moral being. Book II analyses sovereignty. It is inalienable and indivisible; the general will is always right but the people can be deceived, and factions corrupt it by substituting partial wills. Law must be general in source and object. Since a people cannot easily frame its own laws, a quasi-divine Legislator, like Lycurgus or Calvin, must persuade it, sometimes by invoking the gods. Rousseau discusses the size, wealth and climate a people needs and names Corsica as the one European nation still fit for legislation. Book III separates sovereignty from government, the executive body that applies the laws, and compares democracy, aristocracy and monarchy; a true democracy would suit only a people of gods. Every government tends to degenerate, and the body politic, like the human body, begins to die from birth. Sovereignty cannot be represented: the English are free only at elections. Book IV examines voting, the Roman comitia, the tribunate, dictatorship and the censorship, and ends with the chapter on civil religion, which would banish those who reject a short creed of social dogmas and punish with death anyone who professes the creed and then acts against it. The book was banned in Geneva and burned there in 1762, and it later became a scripture of the French Revolution.

Top Lessons

• Might cannot manufacture right

  Book I, Chapter III argues that yielding to force is an act of necessity or prudence, never of duty: if the stronger may rule, the right vanishes the moment strength changes hands. Legitimate authority must therefore rest on agreement. The argument remains a compact test for any regime that claims obedience simply because it can compel it.

• The general will is not majority opinion

  Rousseau distinguishes the general will, aimed at the common good, from the will of all, a sum of private preferences. The people may be deceived; factions turn citizens into partisans. The concept is powerful because it names the public interest, and dangerous because someone may claim to know it better than the people do.

• Representation as a loss of freedom

  Book III, Chapter XV insists that sovereignty cannot be delegated and mocks the English, who are free only on election day. The claim confronts modern representative democracy with an severe standard of participation and suggests that civic indifference ('What does it matter to me?') is a symptom of political death.

• Every polity carries its own mortality

  Rousseau compares the body politic to a human body that begins to die at birth. Constitutions can be robust or weak, but none is permanent; even Sparta and Rome perished. The lesson is less fatalism than stewardship: citizens can lengthen a state's life by renewing its laws and assemblies.

• The cost of a civic religion

  The final chapter seeks a faith that binds citizens to the laws without the divided loyalties of Christianity. Its tolerance has a hard edge: unbelievers may be banished and hypocrites executed. Reading it shows how a theory of freedom can end in coercion of conscience.

Medical Lens

The treatise is political, but it relies on organic metaphors that a history-of-medicine reader will recognise: the state as a body with a robust or weak constitution, born to die, whose decline can be slowed by good regimen. Rousseau proposes population growth as the surest sign of good government (Book III, Chapter IX), an early demographic criterion that anticipates later public-health thinking about national vitality. The 'stupid and unimaginative animal' turned moral being in Book I, Chapter VIII draws on his theory of natural man from the Discourse on Inequality, which in the same Cole volume questions the need for physicians in a state of nature. Rousseau's own chronic urinary illness and the persecutory fears of his later years are often discussed in retrospective diagnoses; these are interpretive readings and belong to the Confessions rather than this text.

• Book III, Chapter IX

  Rousseau names the increase of population, without colonies or naturalisation, as the decisive mark of good government and dismisses tranquillity that hides depopulation.

• Book III, Chapter XI

  The body politic compared to a human body that begins to die at birth; the constitution of man is nature's work, that of the state the work of art and can be prolonged.

• Book II, Chapter VIII

  Peoples, like men, are docile only in youth; aged peoples resist reform like cowardly patients who rave at the sight of the doctor. Revolutions are compared to illnesses that make individuals forget the past, after which a state may be reborn.
