Utilitarianism

John Stuart Mill's 'Utilitarianism' is a seminal work in moral and political philosophy, serving as a robust defense and elucidation of the utilitarian ethical theory. Published in 1861, it articulates the 'greatest happiness principle,' asserting that actions are right in proportion as they tend to promote happiness, and wrong as they tend to produce the reverse of happiness. Mill clarifies that happiness here is not mere sensual pleasure, but encompasses intellectual, emotional, and moral development, famously distinguishing between 'higher' and 'lower' pleasures. He directly addresses common criticisms of utilitarianism, arguing that it is not a selfish doctrine, but rather one that aims at the happiness of all sentient beings. The treatise explores the practical application of the principle, discussing its relationship to justice, duty, and individual liberty, positing that a just society is one structured to maximize overall well-being. 'Utilitarianism' remains a cornerstone text, shaping ongoing debates about ethics, public policy, and the nature of the good life.
