Moral universalism (also called moral objectivism) is the meta-ethical position that some system of ethics, or a universal ethic, applies universally, that is, for "all similarly situated individuals", regardless of culture, race, sex, religion, nationality, sexual orientation, gender identity, or any other distinguishing feature. Moral universalism is opposed to moral nihilism and moral relativism. However, not all forms of moral universalism are absolutist, nor are they necessarily value monist; many forms of universalism, such as utilitarianism, are non-absolutist, and some forms, such as that of Isaiah Berlin, may be value pluralist.
In addition to the theories of moral realism, moral universalism includes other cognitivist moral theories, such as the subjectivist ideal observer theory and divine command theory, and also the non-cognitivist moral theory of universal prescriptivism.
According to philosophy professor R. W. Hepburn: "To move towards the objectivist pole is to argue that moral judgements can be rationally defensible, true or false, that there are rational procedural tests for identifying morally impermissible actions, or that moral values exist independently of the feeling-states of individuals at particular times."
Linguist and political theorist Noam Chomsky states: "if we adopt the principle of universality: if an action is right (or wrong) for others, it is right (or wrong) for us. Those who do not rise to the minimal moral level of applying to themselves the standards they apply to others—more stringent ones, in fact—plainly cannot be taken seriously when they speak of appropriateness of response; or of right and wrong, good and evil."
An early example of moral universalism can be found in Judaism: the Seven Laws of Noah (שבע מצוות בני נח, Sheva Mitzvot B'nei Noach), a set of imperatives which, according to the Talmud, were given by God as a binding set of universal moral laws for the "sons of Noah" – that is, all of humanity.
