The social, educational and political writings of Jean--Jacques Rousseau have become enormously influential in the 200 years since his death. But the breadth as well as the depth of Rousseaua s achievement -- he was amongst other things a creative writer and musical composer as well as a philosopher -- is not always appreciated. In around 100 articles, alphabetically arranged and fully cross--referenced, N. J. H. Dent explores all facets of Rousseaua s work and thoughts, while his subjecta s remarkable life is summarized in a biographical introduction. Details of works by and about Rousseau are listed in an extensive bibliography. For students or general readers seeking an introduction to Rousseaua s work, and for those already familiar with the material who require a convenient reference source, this dictionary is essential reading.
