Rousseau was a great revolutionary. Led partly by personal feeling and partly by sympathy for the common people he revolted against the social inequalities of his age. He propounded in place the old law of reason, the new gospel of faith in nature. Although Rousseau possessed an unusual power of embodying great idea in words, he had very slight ability to relate them in action. His great contribution in field of education was his was his educational methods by showing the value of motivation, creating the problems, and utilizing the senses and activities of the child. His concept of freedom, growth, interests and activities were greatly needed at the time against authoritarianism and absolutism in education. In the future, if Cambodia education factor can assimilate his philosophy to make effective reforms in educational system through curriculum reform, manual reform, teaching methodology reform, principles of assessment reform and basic instructional material reform, It would be the best way to let the young generation know the ways how to conceptualize through the new things so that they can improve their cognitive and motor skills.
Rousseau returned to France in June 1767 under the protection of the Prince de Conti. Wandering from place to place, he at last settled in 1770 in Paris. There he made a living, as he often had in the past, by copying music. By December 1770 the Confessions, upon which he had been working since 1766, was completed, and he gave readings from this work at various private homes. His last work, Les Rêveries du promeneur solitaire, begun in 1776 and unfinished at his death, records how Rousseau, an outcast from society, recaptured "serenity, tranquility, peace, even happiness."
The first part is largely an historical survey. Using specific examples, Rousseau shows how societies in which the arts and sciences flourished more often than not saw the decline of morality and virtue. He notes that it was after philosophy and the arts flourished that ancient Egypt fell. Similarly, ancient Greece was once founded on notions of heroic virtue, but after the arts and sciences progressed, it became a society based on luxury and leisure. The one exception to this, according to Rousseau, was Sparta, which he praises for pushing the artists and scientists from its walls. Sparta is in stark contrast to Athens, which was the heart of good taste, elegance, and philosophy. Interestingly, Rousseau here discusses Socrates, as one of the few wise Athenians who recognized the corruption that the arts and sciences were bringing about. Rousseau paraphrases Socrates’ famous speech in the Apology . In his address to the court, Socrates says that the artists and philosophers of his day claim to have knowledge of piety, goodness, and virtue, yet they do not really understand anything. Rousseau’s historical inductions are not limited to ancient civilizations, however, as he also mentions China as a learned civilization that suffers terribly from its vices.
