[From English consequential: following something else, especially as an effect or result; derived from Latin consequi: to follow closely.]
(ethics) The view that ethical decisions are best or properly made on the basis of the expected outcome or consequences of the action. Both pragmatism and utilitarianism are forms of consequentialism. Because consequentialism tends to focus on the impact of an action on persons other than the actor, in general it is a variety of altruism rather than egoism.
