What is Utilitarianism about?

"Because Utilitarianism is a work of enduring value, it is easy to forget that Mill meant for it to be a topical and relevant contribution to the moral debates of his time. In this edition of Mill's essay, Colin Heydt situates the work in its historical context by supplementing the text of the essay with appendices containing excerpts of related works by Mill's predecessors, Mill himself, and prominent critics of his views. The historical richness of this edition of Utilitarianism would surely have pleased Mill, and will surely benefit today's readers." Ben Eggleston, University of Kansas -- "Colin Heydt has made judicious choices about which additional readings to place alongside Utilitarianism itself. In addition, his clearly written introduction paints a very plausible and attractive portrait of Mill as a committed moral reformer, albeit one who recognized that the improvement of the received morality must proceed incrementally. This volume is well suited both for introducing Mill to students and as a resource for scholars who would like to have the most pertinent texts in easy reach." Dale E. Miller, Old Dominion University -- John Stuart Mill's Utilitarianism is a philosophical defence of utilitarianism, a moral theory stating that right actions are those that tend to promote overall happiness. The essay first appeared as a series of articles published in Fraser's Magazine in 1861; the articles were collected and reprinted as a single book in 1863. Mill discusses utilitarianism in some of his other works, including On Liberty and The Subjection of Women, but Utilitarianism contains his only sustained defence of the theory. -- In this Broadview Edition, Colin Heydt provides a substantial introduction that will enable readers to understand better the polemical context for Utilitarianism. Heydt shows, for example, how Mill's moral philosophy grew out of political engagement, rather than exclusively out of a speculative interest in determining the nature of morality. Appendices include precedents to Mill's work, reactions to Utilitarianism, and related writings by Mill. --Book Jacket.

A glimpse inside

Illustration for Utilitarianism
The Greatest Happiness Principle

Mill’s central claim is that actions are right in proportion as they promote happiness, and wrong as they produce the reverse. Happiness, in this context, means pleasure and the absence of pain. This ‘greatest happiness principle’ is the cornerstone of utilitarian ethics: the moral worth of an action is determined by its consequences for overall well-being. Mill refines this idea by arguing that not all pleasures are equal — some are higher, more valuable forms of happiness than others.

Quality vs. Quantity of Pleasures

Unlike earlier utilitarians such as Bentham, who focused on the amount of pleasure, Mill insists that the quality of pleasure matters. He famously distinguishes between ‘higher’ (intellectual, moral, aesthetic) and ‘lower’ (bodily, sensual) pleasures, claiming that those who have experienced both will prefer the former. This move allows Mill to defend utilitarianism against the charge that it is a doctrine fit only for ‘swine’—that is, that it values only base pleasures.

Popular quotes from Utilitarianism

It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied.
Actions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness.
