On Liberty

Published in 1859, On Liberty is John Stuart Mill’s influential defence of individual freedom against the coercive power of the state, social convention and public opinion. Mill argues that adults should be free to think, speak and live as they choose, provided they do not cause harm to others. His discussion ranges across freedom of expression, individuality, education and the dangers of a majority imposing its preferences upon dissenting minorities.

Written at a pivotal moment in the development of modern liberal thought, the essay remains central to debates about censorship, personal autonomy and the limits of political authority. Mill’s argument is not simply that freedom protects individual rights, but that open disagreement and diverse ways of living are necessary for intellectual and social progress. Clear, forceful and remarkably contemporary in its concerns, On Liberty is one of the foundational works of political philosophy.
