J.-J. Rousseau is the most original, most profound and most controversial of all the great eighteenth-century writers. The problems he raised have since become even more acute and the search for a solution increasingly desirable. His voice was a dissonant one in an age which found satisfaction in material progress, correlates the well-being of humanity with the advancement of kwledge, and displayed a form of complacency which Rousseau sets out to shatter. His message falls uneasily on the ears of the acquisitive society. This volume contains the proceedings of a colloquium held in 1978 in Trinity College, Cambridge, to commemorate the bicentenary of Rousseau's death. It contains the complete text of the fourteen papers given before an invited audience by leading specialists, covering politics, sociology, language, literature and music. It also contains a slightly abridged version of the discussions to which these papers gave rise.
