By the social compact we have given the body politic existence and life: we have now by legislation to give it movement and will. For the original act by which the body is formed and united still in no respect determines what it ought to do for its preservation. What is well and in conformity with order is so by the nature of things and independently of human conventions. All justice comes from God, who is its sole source; but if we knew how to receive so high an inspiration, we should need neither government nor laws. Doubtless, there is a universal justice emanating from reason alone; but this justice, to be admitted among us, must be mutual. 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 nave 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. But what, after all, is a law? As long as we remain satisfied with attaching purely metaphysical ideas to the word, we shall go on arguing without arriving at an understanding; and when we have defined a law of nature, we shall be no nearer the definition of a law of the State. I have already said that there can be no general will directed to a particular object. Such an object must be either within or outside the State. If outside, a will which is alien to it cannot be, in relation to it, general; if within, it is part of the State, and in that case there arises a relation between whole and part which makes them two separate beings, of which the part is one, and the whole minus the part the other. But the whole minus a part cannot be the whole; and while this relation persists, there can be no whole, but only two unequal parts; and it follows that the will of one is no longer in any respect general in relation to the other. But when the whole people decrees for the whole people, it is considering only itself; and if a relation is then formed, it is between two aspects of the entire object, without there being any division of the whole. In that case the matter about which the decree is made is, like the decreeing will general. This act is what I call a law.
