On Liberty의 저자 소개

John Stuart Mill (1806–1873), author of On Liberty, was a pioneering English philosopher, political economist, and advocate for individual freedom, whose work remains foundational to modern liberal thought. A key figure in the utilitarian movement shaped by Jeremy Bentham, Mill’s writings bridge ethics, political theory, and social reform.

On Liberty (1859), a cornerstone of political philosophy, argues for minimal state interference in personal choices through its seminal “harm principle” while championing free speech and intellectual diversity. Mill’s expertise stemmed from his rigorous education under his father, James Mill, and his career as a Member of Parliament, where he advocated for women’s suffrage and workers’ rights.

His other influential works, including Utilitarianism, The Subjection of Women, and Principles of Political Economy, further explore themes of justice, equality, and economic theory. Translated into over 20 languages, On Liberty has sold millions of copies and is widely taught in political science and philosophy curricula, cementing Mill’s legacy as one of the 19th century’s most impactful thinkers.
