"On Liberty" by John Stuart Mill is a landmark philosophical text that explores the nature and limits of individual freedom in society. Published in 1859, Mill argues that personal autonomy should be protected from the constraints of social norms and government intervention, except when one’s actions harm others. The work delves deeply into the tension between individual liberty and the power of society, offering a robust defense of freedom of expression, the right to self-determination, and the importance of diversity in thought.

Mill’s book remains a cornerstone of liberal thought, influencing generations of thinkers, lawmakers, and activists. Through his exploration of free speech, the rights of minorities, and the dangers of the "tyranny of the majority," Mill advocates for a society that nurtures the development of its citizens through liberty, education, and engagement. "On Liberty" continues to be a crucial work for anyone interested in the philosophy of freedom, justice, and the role of government in personal lives.
