For two centuries the works of Jean-Jacques Rousseau have been read and reread and perpetually annotated. Rousseau's ideas on education were so original when first published in 1762 that they still have claims to novelty. In the cause of education he has been a great incitor of ideas in others, the initiator of the modern movement, the ©leader© of most of the educators who came after him. Gabriel Compayré is the author of History of Pedagogy, Montaigne and the Education of the Judgment, Peter Abelard and the Rise of the Modern Universities and Jean Frederich Herbart and Education by Instruction.
