L'Émile and Du contrat social

L'EL'Émile ou de l'éducation remains one of the world's greatest speculative treatises on education. However, Rousseau wrote to a correspondent who tried to follow L'Émile literally, "so much the worse for you!" The work was intended as illustrative of an educational program rather than prescriptive of every practical detail of a proper education. Its overarching spirit is best sensed in opposition to John Locke's essay on education. Locke taught that man should be educated to the station for which he is intended. There should be one education for a prince, another for a physician, and still another for a farmer. Rousseau advocated one education for all. Man should be educated to be a man, not to be a doctor, lawyer, or priest. Nor is a child merely a little man; he is, rather, a developing creature, with passions and powers that vary according to his stage of development. What must be avoided at all costs is the master-slave mode of instruction, with the pupil as either master or slave, for the medium of instruction is far more influential than any doctrine taught through that medium. Hence, an education resting merely on a play of wills - as when the child learns only to please the instructor or when the teacher "teaches" by threatening the pupil with a future misfortune - produces creatures fit to be only masters or slaves, not free men. Only free men can realize a "natural social order," wherein men can live happily.
A few of the striking doctrines set forth in L'Émile are: the importance of training the body before the mind, learning first through "things" and later through words, teaching first only that for which a child feels a need so as to impress upon him that thought is a tool whereby he can effectively manage things, motivating a child by catering to his ruling passion of greed, refraining from moral instruction until the awakening of the sexual urge, and raising the child outside the doctrines of any church until late adolescence and then instructing him in the religion of conscience. Although Rousseau's principles have never been fully put into practice, his influence on educational reformers has been tremendous.
L'Émile's companion master work, Du contrat social, attempted to spell out the social relation that a properly educated man - a free man - bears to other free men. This treatise is a difficult and subtle work of a penetrating intellect fired by a great passion for humanity. The liberating fervor of the work, however, is easily caught in the key notions of popular sovereignty and general will. Government is not to be confused with sovereignty of the people or with the social order that is created by the social contract. The government is an intermediary set up between the people as law followers and the people as law creators, the sovereignty. Furthermore, the government is an instrument created by the citizens through their collective action expressed in the general will. The purpose of this instrument is to serve the people by seeing to it that laws expressive of the general will of the citizens are in fact executed. In short, the government is the servant of the people, not their master. And further, the sovereignty of the people - the general will of the people - is to be found not merely in the will of the majority or in the will of all but rather in the will as enlightened by right judgment.
As with L'Émile, Du contrat socialis a work best understood as elaborating the principles of the social order rather than schematizing the mechanism for those general principles. Rousseau's political writings more concerned with immediate application include his Considérations sur le gouvernement de la Pologne (1772) and his incomplete Projet de constitution pour la Corse, published posthumously in 1862.
Other writings from Rousseau's middle period include the Encyclopédie article Économie politique (1755); Lettre sur la Providence (1756), a reply to Voltaire's poem on the Lisbon earthquake; Lettre a‧ d'Alembert sur les spectacles (1758); Essai sur l'origine des langues (1761); and four autobiographical Lettres a‧ Malesherbes (1762).
