On Liberty

On Liberty is one of the most influential essays ever written on the relationship between the individual and society. Published in 1859, it asks a question that remains urgent today: how much power can society legitimately exercise over a person's life? John Stuart Mill argues that the only justification for interfering with someone's freedom is to prevent harm to others. From this simple principle, he builds a powerful defense of free speech, individuality, and the right to live as one chooses.

This book is for anyone interested in politics, philosophy, or the ongoing debate about personal freedom. It will appeal to students of history and political theory, book clubs looking for a challenging but rewarding read, and general readers who want to understand the foundations of liberal thought. Mill's clear prose and careful reasoning make his arguments accessible, even as they provoke deep reflection.

This edition contains the complete text of On Liberty, a new introduction, a guide to key ideas, a summary, themes, a glossary, and discussion questions. It is designed to help you engage with Mill's ideas and consider their relevance to the world we live in now.
