Definition of Utilitarianism

Utilitarianism is the idea that the moral worth of an action is determined solely by its utility in providing happiness or pleasure as summed among all sentient beings. It is thus a form of consequentialism, meaning that the moral worth of an action is determined by its outcome.

Utilitarianism is often described by the phrase "the greatest good for the greatest number of people"[1], and is also known as "the greatest happiness principle". Utility, the good to be maximized, has been defined by various thinkers as happiness or pleasure (versus suffering or pain), although preference utilitarians define it as the satisfaction of preferences. It may be described as a life stance, with happiness or pleasure being of ultimate importance.

Utilitarianism can be characterised as a quantitative and reductionist approach to ethics. It can be contrasted with deontological ethics (which do not regard the consequences of an act as being a determinant of its moral worth) and virtue ethics (which focuses on character), as well as with other varieties of consequentialism.


In general usage, the term utilitarian (Katrin Joost) refers to a somewhat narrow economic or pragmatic viewpoint. Philosophical utilitarianism, however, is a much broader view that encompasses all aspects of people's lives.
