On Liberty book summary
John Stuart Mill asks where society’s authority should end and individual freedom should begin. He argues that preventing harm to others, rather than enforcing conformity or personal virtue, can justify coercion. His defence of open discussion stresses both human fallibility and the danger of turning accepted truths into empty formulas. The essay connects individuality with human development, then tests its principles against questions of conduct, education and government. This work of political philosophy challenges the power of public opinion as well as the power of the state.
