Take a swim at Tiber River . The Social Contract Du Contrat Social, ou Principes du droit politique , is the title of a work written by J.J. Rousseau and published in 1762. The Contrat Social is but a fragment of this treatise. The Contrat Social is divided into four books. The first treats of the formation of societies and the social contract.
Social order is a sacred right which is at the foundation of all other rights.
It does not come from nature. Again, social order is not based on force, for the strongest is not strong enough to retain at all times his supremacy unless he transforms force into right, and obedience into duty. But in that case right would change places with force. All legitimate authority among men is based on an agreement. This argument, according to Grotius, has its foundation in the right of a people to alienate its freedom.
