Consequentialism is the class of normative ethical theories holding that the of one's conduct are the ultimate basis for any judgment about the rightness or wrongness of that conduct. Thus, from a consequentialist standpoint, a morally right act (or omission from acting) is one that will produce a good outcome, or consequence. In an extreme form, the idea of consequentialism is commonly encapsulated in the saying, "the end justifies the ", meaning that if a goal is morally important enough, any method of achieving it is acceptable.
Consequentialism is usually contrasted with deontological ethics (or deontology), in that deontology, in which rules and moral duty are central, derives the rightness or wrongness of one's conduct from the character of the behaviour itself rather than the outcomes of the conduct. It is also contrasted with virtue ethics, which focuses on the character of the agent rather than on the nature or consequences of the act (or omission) itself, and pragmatic ethics which treats morality like science: advancing socially over the course of many lifetimes, such that any moral criterion is subject to revision. Consequentialist theories differ in how they define moral goods.
Some argue that consequentialist and deontological theories are not necessarily mutually exclusive. For example, T. M. Scanlon advances the idea that human rights, which are commonly considered a "deontological" concept, can only be justified with reference to the consequences of having those rights. Similarly, Robert Nozick argues for a theory that is mostly consequentialist, but incorporates inviolable "side-constraints" which restrict the sort of actions agents are permitted to do.
It is the business of the benevolent man to seek to promote what is beneficial to the world and to eliminate what is harmful, and to provide a model for the world. What benefits he will carry out; what does not benefit men he will leave alone.
Mohist consequentialism, also known as state consequentialism, is an ethical theory which evaluates the moral worth of an action based on how much it contributes to the welfare of a state. According to the Stanford Encyclopedia of Philosophy, Mohist consequentialism, dating back to the 5th century BCE, is the "world's earliest form of consequentialism, a remarkably sophisticated version based on a plurality of intrinsic goods taken as constitutive of human welfare." Unlike utilitarianism, which views utility as the sole moral good, "the basic goods in Mohist consequentialist thinking are... order, material wealth, and increase in population". During Mozi's era, war and famines were common, and population growth was seen as a moral necessity for a harmonious society. The "material wealth" of Mohist consequentialism refers to basic needs like shelter and clothing, and the "order" of Mohist consequentialism refers to Mozi's stance against warfare and violence, which he viewed as pointless and a threat to social stability.Stanford sinologist David Shepherd Nivison, in the The Cambridge History of Ancient China, writes that the moral goods of Mohism "are interrelated: more basic wealth, then more reproduction; more people, then more production and wealth... if people have plenty, they would be good, filial, kind, and so on unproblematically." The Mohists believed that morality is based on "promoting the benefit of all under heaven and eliminating harm to all under heaven." In contrast to Jeremy Bentham's views, state consequentialism is not utilitarian because it is not hedonistic or individualistic. The importance of outcomes that are good for the community outweigh the importance of individual pleasure and pain. The term state consequentialism has also been applied to the political philosophy of the Confucian philosopher Xunzi.
