Humanly speaking, in default of natural sanctions, the laws of justice are ineffective among men: they merely make for the good of the wicked and the undoing of the just, when the just man observes them towards everybody and nobody observes them towards him. Conventions and laws are therefore needed to join rights to duties and refer justice to its object. In the state of nature, where everything is common, I owe nothing to him whom I have promised nothing; I recognise as belonging to others only what is of no use to me. In the state of society all rights are fixed by law, and the case becomes different.
