"Man was born free, and he is everywhere in chains" - these are the famous opening words of a treatise that has not ceased to stir vigorous debate since its first publication in 1762. Rejecting the view that anyone has a natural right to wield authority over others, Rousseau argues instead for a pact, or "social contract", that should exist between all the citizens of a state and that should be the source of sovereign power. From this fundamental premise, he goes on to consider issues of liberty and law, freedom and justice, arriving at a view of society that has seemed to some a blueprint for totalitarianism, to others a declaration of democratic principles.
