John Stuart Mill
Mill's classic defense of judging actions by happiness, suffering, higher pleasures, conscience, and justice.
5-minute overview
Utilitarianism defends the idea that actions are right when they tend to promote happiness and wrong when they tend to produce suffering. Mill answers the charge that this view is crude or selfish by distinguishing higher and lower pleasures and by insisting that everyone's happiness counts. He explains why people can feel obligated to follow utility, offers a philosophical proof of the principle, and devotes the final chapter to justice. His main claim is that justice, rights, and moral rules matter because they protect the deep conditions of human happiness.
Why it matters: It is one of the most assigned and debated short works in modern ethics.
Modern relevance: It applies to public policy, law, medicine, technology ethics, education, and any decision that weighs benefits and harms across many people.

Section 1
Chapter 1 frames the problem. Mill argues that ethics needs a clear first principle, just as other fields need basic assumptions. He introduces utility as the standard that can organize moral reasoning, even when people do not openly name it.
Read sectionSection 2
Chapter 2 gives the core definition of utilitarianism and answers common objections. Mill argues that happiness includes quality, not just quantity, and that moral agents should consider the happiness of all affected people, not only their own pleasure.
Read sectionSection 3
Chapter 3 explains the force behind utilitarian morality. Laws, praise, blame, and education can encourage useful conduct, but the deeper support is internal: people can come to feel the happiness of others as part of what conscience demands.
Read sectionSection 4
Chapter 4 offers Mill's famous proof. He reasons that the only evidence something is desirable is that people desire it. Since people desire happiness, happiness is a good; since each person's happiness is good to that person, general happiness is good to all together.
Read sectionSection 5
Chapter 5 connects justice with utility. Mill analyzes punishment, rights, fairness, desert, and equality, then argues that justice has special emotional force because it protects the basic conditions of social life. Utility does not erase justice; it explains why justice matters so much.
