For everyone

According to utilitarianism, whether an action is right depends on how much its consequences increase the total happiness of everyone. Bentham expressed this as "the greatest happiness of the greatest number". Mill argued that pleasures differ in quality. The view has shaped debates on animal rights and global poverty. Critics argue that individual rights could be sacrificed for the sake of total welfare.

For specialists

Classical utilitarianism combines three elements: consequentialism (only consequences determine rightness), welfarism (well-being is what matters) and equal summation. Act utilitarianism assesses each act on its own; rule utilitarianism looks to the rules whose general observance gives the best outcome. Utility can be defined as the balance of pleasure over pain (hedonism) or as preference satisfaction. How to compare utility across persons is an open problem.

Claims

Positions

Kantian (deontological) ethics
Some actions are wrong whatever their consequences; people must never be used merely as a means.[4]
Rawls
In adding up benefits across people, utilitarianism does not take seriously the distinction between persons; justice must attend to the position of the worst off.[3]
Singer
The interests of every being that can suffer should count equally, which changes how animals are treated and what we owe in aid.[4]
