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.
