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, 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 (Hebrew: 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. The Seven Laws of Noah include prohibitions against worshipping idols, cursing God, murder, adultery, bestiality, sexual immorality, theft, eating flesh torn from a living animal, as well as the obligation to establish courts of justice. The Jewish sages expanded the concept of universal morality within the Seven Laws of Noah and added several other laws beyond the seven listed in the Talmud and Tosefta, such as prohibitions against committing incest, cruelty to animals, pairing animals of different species, grafting trees of different kinds, castration, emasculation, homosexuality, pederasty, and sorcery among others, with some of the sages going so far as to make a list of 30 laws. The Talmud expands the scope of the Seven Laws of Noah to cover about 100 of the 613 Jewish commandments.
The United Nations' Universal Declaration of Human Rights can be read as assuming a kind of moral universalism. The drafting committee of the Universal Declaration did assume, or at least aspired to, a "universal" approach to articulating international human rights. Although the Declaration has undeniably come to be accepted throughout the world as a cornerstone of the international system for the protection of human rights, a belief among some that the Universal Declaration does not adequately reflect certain important worldviews has given rise to more than one supplementary declaration, such as the Cairo Declaration on Human Rights in Islam and the Bangkok Declaration.
Global environmental treaties may also assume and present a moral universalism. The United Nations Framework Convention on Climate Change is founded upon the "common heritage of mankind". Protecting this heritage is presented in the treaty as a shared moral duty requiring protective actions based on "common but differentiated responsibilities". This has been criticised as anthropocentric and state-centric but it does assert universal goals.
In his Groundwork of the Metaphysics of Morals, Immanuel Kant attempts to derive a supreme principle of morality that binds all rational agents. Similarly, divine command theory presents a form of universalism, by way of the unconditional morality of God's commandments.
According to Immanuel Kant and Richard Mervyn Hare...moral imperatives must be regarded as equally binding on everyone.
Let us say that moral objectivism maintains that moral judgments are ordinarily true or false in an absolute or universal sense, that some of them are true, and that people sometimes are justified in accepting true moral judgments (and rejecting false ones) on the basis of evidence available to any reasonable and well-informed person.
Noahide Laws, also called Noachian Laws, a Jewish Talmudic designation for seven biblical laws given to Adam and to Noah before the revelation to Moses on Mt. Sinai and consequently binding on all mankind. Beginning with Genesis 2:16, the Babylonian Talmud listed the first six commandments as prohibitions against idolatry, blasphemy, murder, adultery, and robbery and the positive command to establish courts of justice (with all that this implies). After the Flood a seventh commandment, given to Noah, forbade the eating of flesh cut from a living animal (Genesis 9:4). Though the number of laws was later increased to 30 with the addition of prohibitions against castration, sorcery, and other practices, the “seven laws,” with minor variations, retained their original status as authoritative commandments and as the source of other laws. As basic statutes safeguarding monotheism and guaranteeing proper ethical conduct in society, these laws provided a legal framework for alien residents in Jewish territory. Maimonides thus regarded anyone who observed these laws as one “assured of a portion in the world to come.”CS1 maint: extra text: authors list (link)
