Jean-Jacques Rousseau

Enlightenment · Europe · 1712 to 1778

Writer from Geneva who held that people are good by nature but bent by unequal societies. He said fair rule rests on the "general will".

What it is

Jean-Jacques Rousseau (1712 to 1778) was a writer and philosopher born in Geneva who held that human beings are good by nature and are corrupted by society, and who tried to describe a community in which people can be free and equal because they obey a will that is their own. He is one of the most influential thinkers of the Enlightenment, though he was also one of its sharpest critics.

His work came to public notice when his essay on the sciences and the arts won a prize from the Academy of Dijon with the unexpected claim that their progress had corrupted virtue and morals. In 1762 he published two books that caused uproar, The Social Contract on politics and Emile on education. Both were condemned and banned in France, and Rousseau fled the country. He died in 1778, and his ideals were later championed by leaders of the French Revolution.

The main ideas

• Good by nature, corrupted by society. In his second major essay, on the origin of inequality, he argues that human beings are basically good by nature but were corrupted by the complex historical events that produced present-day civil society.
• Two kinds of self-love. He separates a natural self-love, amour de soi, which simply cares for one's own life, from amour-propre, a self-love that depends on how others see us. The second, he thought, is what eats away at freedom and authenticity in modern society.
• The general will. In The Social Contract he asks how people can live under laws and still be as free as they were before. His answer rests on the general will, the collective will of the citizens taken as a whole, so that in obeying the law each person obeys a will that is partly their own.
• Education. Emile is his book on how to bring up a child so that the child's independence is encouraged and the worst forms of self-interest do not take root.

What it looks like in practice

Picture a town meeting that must decide whether to build a road through a field. Each person has private interests, and the question is what everyone together should want. Rousseau's idea is that citizens should try to ask not 'what is best for me?' but 'what is best for all of us as members of this community?', and that a law passed in that spirit is one each citizen can recognise as their own. This is an illustration of the idea, not an example he gave.

Books and moments

• Discourse on the Sciences and the Arts brought him fame.
• Discourse on the Origin of Inequality was his second major essay. It develops the idea that people are good by nature and are corrupted by society.
• The Social Contract and Emile (both 1762) are his main works on politics and education.
• The Confessions is his autobiography, written late in life.

Questions and criticism

• What is the general will? Scholars read it in different ways. Is it what the people actually vote for, or what they would choose if they reasoned only about the common good? The answer changes how much freedom the idea leaves each person.
• Are we good by nature? His claim that people are naturally good and corrupted by society is hard to test. It is fair to ask what could count as evidence for or against it.
• Quarrels. He quarrelled with many friends and contemporaries, including Voltaire and David Hume, and the end of his life was marked by suspicion of those around him.

Close neighbours

Rousseau belongs to the same circle of social contract thinkers as Hobbes and Locke, though he drew different conclusions. The pages on Hobbes and Locke show the other main versions of the idea, and the page on liberalism follows how it was used later.
