Summary

British philosopher and political economist who refined utilitarianism, developed the harm principle as the foundation of liberal politics, and was an early champion of women's suffrage.

Core Contribution

Utilitarianism: the greatest happiness of the greatest number — but distinguishing quality of pleasures (higher vs. lower). On Liberty: the harm principle — the only legitimate reason to restrict individual liberty is to prevent harm to others. The Subjection of Women: a systematic argument for women's equality. A System of Logic: the inductive basis of the social sciences.

Key Spikes & Highlights

Had a mental breakdown at 20 — he had been educated entirely by his father from age 3, learning Greek at 3 and logic at 8. His Autobiography describes the crisis and recovery through poetry (Wordsworth).
His relationship with Harriet Taylor (and their eventual marriage) was scandalous in Victorian England — they wrote several major works together and he attributed much of his thought to her.
