The ethical theory of John Stuart Mill (1806-1873) is most extensively articulated in his classical text Utilitarianism (1861). Its goal is to justify the utilitarian principle as the foundation of morals. This principle says actions are right in proportion as they tend to promote overall human happiness. So, Mill focuses on consequences of actions and not on rights nor ethical sentiments.
This article primarily examines the central ideas of his text Utilitarianism, but the article’s last two sections are devoted to Mill’s views on the freedom of the will and the justification of punishment, which are found in System of Logic (1843) and Examination of Sir William Hamilton’s Philosophy (1865), respectively.
