In political philosophy, the general will (French: volonté générale) is the will of the people as a whole. The term was made famous by 18th-century French philosopher Jean-Jacques Rousseau.
The phrase "general will," as Rousseau used it, occurs in Article Six of the Declaration of the Rights of Man and the Citizen (French: Déclaration des droits de l'Homme et du citoyen), composed in 1789 during the French Revolution:
The law is the expression of the general will. All citizens have the right to contribute personally, or through their representatives, to its formation. It must be the same for all, whether it protects or punishes. All citizens, being equal in its eyes, are equally admissible to all public dignities, positions, and employments, according to their capacities, and without any other distinction than that of their virtues and their talents.
James Swenson writes:
To my knowledge, the only time Rousseau actually uses the formulation "expression of the general will" is in a passage of the Discours sur l'économie politique, whose content renders it little susceptible of celebrity.. . . But it is indeed a faithful summary of his doctrine, faithful enough that commentators frequently adopt it without any hesitation. Among Rousseau's definitions of law, the textually closest variant can be found in a passage of the Lettres écrites de la montagne summarizing the argument of Du contrat social, in which law is defined as "a public and solemn declaration of the general will on an object of common interest."
As used by Rousseau, the "general will" is considered by some identical to the rule of law, and to Spinoza's mens una.
The notion of the general will is wholly central to Rousseau's theory of political legitimacy . . . . It is, however, an unfortunately obscure and controversial notion. Some commentators see it as no more than the dictatorship of the proletariat or the tyranny of the urban poor (such as may perhaps be seen in the French Revolution). Such was not Rousseau's meaning. This is clear from the Discourse on Political Economy, where Rousseau emphasizes that the general will exists to protect individuals against the mass, not to require them to be sacrificed to it. He is, of course, sharply aware that men have selfish and sectional interests which will lead them to try to oppress others. It is for this reason that loyalty to the good of all alike must be a supreme (although not exclusive) commitment by everyone, not only if a truly general will is to be heeded but also if it is to be formulated successfully in the first place".
