Utilitarianism

Utilitarianism is the ethical doctrine that the moral worth of an action is determined solely by its contribution to overall utility. It is thus a form of consequentialism, meaning that the moral worth of an action is determined by its outcome. Utility — the good to be maximized — has been defined by various thinkers as happiness or pleasure (versus suffering or pain), though preference utilitarians like Peter Singer define it as the satisfaction of preferences. Utilitarians tend to consider the interests of any entity capable of experiencing pleasure or pain.
