Jean Jacques Rousseau(1712-1778) was a Swiss philosopher and musical theorist whose ideas had a significant impact on politics, religion and education.

One of his better known concepts is that of the 'noble savage': the idea that mankind is born in a state of 'natural goodness' which is then corrupted by an individual's experiences in the world.
