Discover On Liberty by John Stuart Mill — one of the most influential works of political philosophy ever written and a foundational text of liberal thought.

In On Liberty, Mill makes a passionate and rigorous case for the protection of individual liberty against the tyranny of both government and social conformity. He introduces his influential "harm principle" — the idea that the only justification for restricting a person's freedom is to prevent harm to others — and argues fiercely for freedom of speech and thought, even when those views are unpopular or offensive. Mill contends that a diversity of opinions and ways of living is essential not only for individual flourishing but for the progress of society as a whole.
