Moral Relativism

Moral relativism is the metaethical doctrine that the truth or justification of moral judgments is not absolute but relative to the standards of a particular culture, historical period, or individual. Its intellectual lineage runs from the Greek Sophists—Protagoras's dictum that "man is the measure of all things" (Plato, Theaetetus, c. 369 BCE)—through the Pyrrhonist skeptics, who catalogued the divergence of customs to suspend judgment. The modern formulation owes much to the anthropological turn of the late nineteenth and early twentieth centuries, particularly the cultural anthropology of Franz Boas and his students Ruth Benedict and Melville Herskovits, whose 1947 statement to the American Anthropological Association on the Universal Declaration of Human Rights warned against imposing one civilization's values on another. For the civil-services aspirant, relativism is the standard foil against which moral universalism, deontology, and utilitarianism are tested in the GS Paper IV ethics syllabus.

It is essential to distinguish the three principal variants the examiner expects a candidate to disambiguate. Descriptive moral relativism is an empirical claim: it observes only that different societies in fact hold divergent moral codes—infanticide tolerated in some, abhorred in others—and makes no normative assertion. Meta-ethical relativism is the philosophically loaded thesis: it holds that there is no objective standpoint from which one code can be judged superior, so the truth-value of a moral statement is indexed to a framework. Normative relativism, the most contested, draws a prescriptive conclusion: that one ought to tolerate practices that differ from one's own because no external standard licenses interference. The slide from the descriptive observation to the normative prescription is logically illicit—a fact of disagreement does not entail that no party is correct—and identifying this gap is a high-value examination point.

A fourth distinction operates within meta-ethical relativism between cultural (or social) relativism, which indexes morality to the conventions of a community, and individual relativism or subjectivism, which indexes it to the preferences of a single person. The latter collapses readily into emotivism—the view associated with A. J. Ayer and C. L. Stevenson that moral utterances merely express attitudes ("Boo!" or "Hurrah!"). Cultural relativism is typically the more defensible position because it preserves the possibility of being mistaken relative to one's own society's standards, whereas individual subjectivism renders every sincere judgment automatically true and thereby dissolves moral error altogether.

Contemporary practice supplies concrete tensions. The "Asian values" debate of the 1990s, articulated by Singapore's Lee Kuan Yew and Malaysia's Mahathir Mohamad at the 1993 Vienna World Conference on Human Rights, deployed relativist arguments to resist Western framings of civil and political rights as universal. The Cairo Declaration on Human Rights in Islam, adopted by the Organisation of the Islamic Conference in 1990, subordinated rights to Sharia and is frequently read as a relativist counterweight to the 1948 Universal Declaration. In India, debates over personal law, the practice of female genital cutting among the Dawoodi Bohra community, and Supreme Court interventions such as Shayara Bano v. Union of India (2017) on triple talaq stage the collision between community-relative norms and constitutional universalism.

Moral relativism must be sharply separated from adjacent ideas with which novices conflate it. It is not moral skepticism, which doubts that we can have moral knowledge at all; the relativist affirms moral knowledge but relativizes its content. It differs from tolerance, which is itself a substantive value the consistent relativist cannot universally endorse without contradiction. It is distinct from pluralism in the sense of Isaiah Berlin, who held that genuine values are objectively real yet plural and sometimes incommensurable—pluralism affirms objective goods that conflict, whereas relativism denies objectivity. It also contrasts with situational ethics, which holds that universal principles apply differently according to circumstance but does not deny the principles themselves.

The classic objection, pressed by Bernard Williams and others, is the reformer's dilemma: if morality is whatever a society endorses, then Gandhi's campaign against untouchability or the abolitionists' opposition to slavery were, by definition, immoral at the moment of their own culture, since they violated prevailing norms. Relativism appears to make moral progress unintelligible and to disarm cross-cultural criticism of atrocity. Defenders respond with more sophisticated frameworks—Gilbert Harman's bargaining-based relativism and David Wong's "pluralistic relativism," which permits a constrained set of adequate moralities while ruling out others—seeking a middle path between rigid absolutism and an "anything goes" nihilism. Recent developments include experimental philosophy's empirical surveys of folk metaethical commitments, which find ordinary intuitions oscillate between objectivist and relativist depending on the issue's perceived "thickness."

For the working practitioner—the desk officer, the diplomat, or the ethics-paper candidate—relativism is less a position to adopt than a discipline of analysis. It guards against ethnocentric imposition and cultivates the humility required for negotiation across value systems, yet it cannot be the final word, lest it neutralize the very human-rights vocabulary that multilateral diplomacy depends upon. The mature stance most examiners reward is a qualified universalism: acknowledging genuine cultural variation in custom while insisting on a thin core of cross-cultural moral constraints—against gratuitous cruelty, slavery, and genocide—that no appeal to local convention can override.
