Jean-Jacques Rousseau (28 June 1712 – 2 July 1778) is a 18th century philosopher. His political philosophy influenced the French Revolution. His writings had a deep impact on the modern political, sociological and educational thought.
Émile: or, On Education (1762), a novel, is a treatise on the whole education of an individual for citizenship. Julie, ou la nouvelle Héloïse (1761), a novel which achieved great success when published, was of importance to the romanticism in fiction with its countryside descriptions. Rousseau's autobiographical writings marked a focus on subjectivity and introspection that has since permeated the whole modern era. His Discourse on the Origin of Inequality (1754), where he holds that in the natural state, morals are uncorrupted, and his On the Social Contract (1762), which describes the relationship of man with society, are cornerstones in modern political and social thought.
He died in 1778 at the age of 66.
