About the author
English philosopher, economist, and politician (1806–1873), the leading liberal thinker of the nineteenth century. Raised on Bentham's utilitarianism by his father, Mill revised and humanized it; his works — On Liberty, Utilitarianism, The Subjection of Women — remain foundational to liberalism, ethics, and feminism alike.
Synopsis
Mill argues that the foundation of morals is utility, or the greatest-happiness principle, and answers common objections: that it is a base creed (he distinguishes qualitatively higher pleasures), that happiness is unattainable or unmeasurable, and that it cannot account for justice. He contends that the sense of justice is rooted in the powerful social utility of security, and that rights are claims society ought to defend because doing so serves the general good.
Core passage idea
Paraphrase · Public domainMill holds that actions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse — and that it is better to be a human being dissatisfied than a pig satisfied.
Mill's qualitative distinction among pleasures rescues utilitarianism from the charge of crudity: not all satisfactions count equally, and the cultivated life of mind ranks above mere contentment. His grounding of justice in social utility is the classic attempt to fit rights inside a consequentialist ethics.
To avoid a bubble
Pair with Kant's duty-based ethics and Rawls's theory of justice, both of which argue that utilitarianism wrongly sacrifices the individual and rights to aggregate welfare, and with Bernard Williams's critique of its demand that we maximize impartially.
Reading note
Short and central to moral and political philosophy. Read it as the refined statement of consequentialism, then read Kant and Rawls for the great deontological replies that define the modern debate over justice.

Immanuel Kant, Groundwork of the Metaphysics of Morals; John Rawls, A Theory of Justice.
