Utilitarianism: Happiness as the Greatest Good

A government spends billions, not on roads or weapons, but on “making people happier.” A charity claims a few thousand dollars can likely save a life, and compares that to buying a new laptop. Are these cold calculations… or a radically compassionate way to think about morality?

Economists rank policies by “quality-adjusted life years.” Tech companies A/B test tiny design tweaks to see which version keeps users more “engaged.” Psychologists run massive surveys to track how satisfied people feel in different countries. Slowly, a picture emerges: powerful institutions already behave as if happiness can be counted, compared, and optimized.

Utilitarianism steps in and says: don’t just use those numbers for profit or efficiency—use them to decide what’s right. Jeremy Bentham tried to turn pleasure and pain into something like a ledger. John Stuart Mill then argued that reading a great novel and eating a donut both give pleasure, but not the same *kind*.
