A landmark of moral philosophy and an ideal introduction to ethics, this famous work balances the claims of individuals and society, declaring that all actions should produce the greatest happiness overall. It remains as relevant today as it was to intellectual and moral dilemmas of the 19th century.

This volume includes the complete essay in five chapters: Introductory; Of the Liberty of Thought and Discussion; Of Individuality, as One of the Elements of Well-being; Of the Limits to the Authority of Society over the Individual; and Applications. With a fine introduction by editor Alburey Castell, this edition also includes line numbers for easy reference, a list of principal dates in the life of John Stuart Mill, and a bibliography.
