Genevan philosopher, writer, and composer (1712–1778)
Jean-Jacques Rousseau (UK: , US: ; French: [ʒɑ̃ʒak ʁuso]; 28 June 1712 – 2 July 1778) was a Genevan philosopher (philosophe), writer, and composer. His political philosophy influenced the progress of the Age of Enlightenment throughout Europe, as well as aspects of the French Revolution and the development of modern political, economic, and educational thought. His Discourse on Inequality, which argues that private property is the source of inequality, and The Social Contract, which outlines the basis for a legitimate political order, are cornerstones in modern political and social thought.
