John Stuart Mill's Utilitarianism is one of the most important, controversial, and suggestive works of moral philosophy ever written. Mill defends the view that all human action should produce the greatest happiness overall, and that happiness itself is to be understood as consisting in 'higher' and 'lower' pleasures. This volume uses the 1871 edition of the text, the last to be published in Mill's lifetime. The text is preceded by a comprehensive introduction assessing Mill's philosophy and the alternatives to utilitarianism, and discussing some of the specific issues Mill raises in Utilitarianism. This volume also includes an analysis of the text, substantial endnotes, suggestions for further reading, and a full bibliography.
