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".
