His differences with the philosophes proved to be the impetus for Rousseau's future work on the content of human nature and man's rela-tionship to society and the state. Contrary to the individualism and intel-lectual enlightenment advocated by his contemporaries, Rousseau sought to sublimate individuality in the security of the collective per-sonality known as the general will. This new society would be typified by concern for the community and would be ruled by laws developed through a plan of controlled participation. Rousseau's social theory was developed in his work Julie, ou la Nouvelle Heloise (1761) and in Emile (1762). The institutional structure was constructed in The Social Con-tract (1761).
In Emile, Rousseau presents his utopian vision of child-centered education, full of the sentiments of Romanticism, a movement that Rousseau inspired.
Rousseau's later years were spent fighting off persecution, both real and imaginary. He died near Paris on July 2, 1778.
