Jean-Jacques Rousseau

Jean-Jacques Rousseau was a Genevan philosopher, writer, and composer of the 18th century. His political philosophy influenced the French Revolution as well as the overall development of modern political, sociological, and educational thought.
Rousseau's novel Émile, or On Education is a treatise on the education of the whole person for citizenship. His sentimental novel Julie, or the New Heloise was of importance to the development of pre-romanticism and romanticism in fiction. Rousseau's autobiographical writings — his Confessions, which initiated the modern autobiography, and his Reveries of a Solitary Walker — exemplified the late 18th-century movement known as the Age of Sensibility, and featured an increased focus on subjectivity and introspection that later characterized modern writing. His Discourse on the Origin of Inequality and his On the Social Contract are cornerstones in modern political and social thought. He argued that private property was conventional and the beginning of true civil society.
Rousseau was a successful composer of music, who wrote seven operas as well as music in other forms, and made contributions to music as a theorist.
