Jean-Jacques Rousseau was an 18th century French political philosopher, educationist, and essayist. He was born in Geneva in 1712 and had little formal education. Rousseau believed that mankind is naturally good but corrupted by society. He advocated for education that follows natural human development and allows children to remain uncorrupted. Rousseau's most influential work was Emile, published in 1762, which outlined the ideal education of the title character Emile and his female counterpart Sophie through following their natural development.
