''Man was born free, and everywhere he is in chains.'' These are the famous opening words of a treatise that has stirred vigorous debate ever 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.Translated by Quintin HoareWith a new introduction by Christopher Bertram
