Two-level utilitarianism is a utilitarian theory of ethics according to which a person's moral decisions should be based on a set of moral rules, except in certain rare situations where it is more appropriate to engage in a 'critical' level of moral reasoning. The theory was initially developed by R. M. Hare.[1]
Consequentialists believe that an action is right if it produces the best possible state of affairs.[2] Traditional utilitarianism (act utilitarianism) treats this as a claim that people should try to ensure that their actions maximizes the positive outcome for sentient beings.[3][4][5]
Two-level utilitarianism is virtually a synthesis of the opposing doctrines of act utilitarianism and rule utilitarianism. Act utilitarianism states that in all cases the morally right action is the one which produces the most well-being, whereas rule utilitarianism states that the morally right action is the one that is in accordance with a moral rule whose general observance would create the most well-being. In terms of two-level utilitarianism, act utilitarianism can be likened to the 'critical' level of moral thinking, while rule utilitarianism can be likened to the 'intuitive' level.[6]
