The Greatest Good
In one line Judge an act by what it does for everyone it touches, counting each person alike.
Utilitarians ask one question of an act: what does it do to the well-being of everyone it touches? Bentham’s rule was to count each person as one and nobody as more than one. The right act has the best overall results, so the same act can be right in one setting and wrong in another.
This asks you to widen your view. Who is affected, including people not in the room? How much good or harm does each get, and for how long? A choice that pleases the loudest voice may not do the most good.
The hard parts are real. Some goods are hard to count, and a total can hide one person badly hurt. So check the numbers, ask who bears the cost, and distrust a sum that seems to require something cruel.
Go deeper
Bentham wrote that nature has put humankind under two masters, pain and pleasure. He proposed counting a pleasure’s intensity, duration, certainty and reach, a method often called the hedonic calculus.
Critics, including Rawls, argue that adding up well-being across persons ignores the separateness of persons: one person’s suffering is not repaid by another person’s gain.
The community budget
A village has enough money for one project. One group wants a new playground for twenty children. Another wants to repair the footbridge that two hundred people use every day.
The council lists who benefits and how much, who is hurt by delay, and whether a cheaper playground repair is possible. The bridge helps far more people daily, and the council finds a small fund for the playground’s worst hazard. The choice is reasoned, and the playground group is told why.
Try this today Before your next group decision, list everyone affected and how much each gains or loses.
