The second book of Jean-Jacques Rousseau's "Du Contrat Social, ou Principes du droit politique" (1762) deals with sovereignty and its rights. Sovereignty, or the general will, is inalienable, for the will cannot be transmitted; it is indivisible, since it is essentially general; it is infallible and always right, determined and limited in its power by the common interest; it acts through laws. Law is the decision of the general will in regard to some object of common interest, but though the general will is always right and desires only good, its judgment is not always enlightened, and consequently does not always see wherein the common good lies; hence the necessity of the legislator. But the legislator has, of himself, no authority; he is only a guide who drafts and proposes laws, but the people alone (that is, the sovereign or general will) has authority to make and impose them.
