Moral Relativism

Are any moral judgments objectively and universally true, or are all moral truths relative to cultures, individuals, or perspectives?

Moral relativism is the metaethical view that the truth, justification, or meaning of moral judgments is not absolute but depends on, or is relative to, specific cultural frameworks, individual standpoints, or contextual standards.

Origin
The phrase "moral relativism" arose in late 19th- and early 20th‑century debates in anthropology and philosophy, especially in discussions of cultural diversity and the critique of Victorian moral universalism; it became standard in English-language metaethics by the mid‑20th century.

1. Introduction

Moral relativism is a family of views about the status of moral judgments—claims about right and wrong, good and bad, virtue and vice. Instead of treating such judgments as true or false in a way that is independent of any particular standpoint, relativist positions hold that their truth, justification, or meaning depends on some background framework, such as a culture, a person’s commitments, or an assessor’s standards.

This entry situates moral relativism within metaethics, the branch of moral philosophy that examines what moral claims mean, whether they can be true or false, and how (if at all) we can know them. Moral relativism is usually contrasted with moral objectivism or universalism, which maintain that at least some moral truths are valid for all persons regardless of culture or perspective.

Historical reflection on moral relativism spans from ancient Greek debates about nomos (custom) and physis (nature), through medieval religious moral theories, to modern anthropological and philosophical discussions of cultural diversity and historical change. Contemporary philosophers have developed more precise versions of relativism, especially in the semantics of moral language and in theories of truth.

Because “relativism” is a contested term, this entry distinguishes between different forms—cultural relativism, individual (subjective) relativism, and appraiser relativism—and relates them to neighboring ideas such as moral pluralism and moral skepticism. It also surveys major arguments for and against relativism, its links to scientific, religious, and political debates, and its implications for issues such as tolerance, moral criticism, and human rights.

Readers should note that “moral relativism” names both a family of philosophical theses and a broader cultural label often used polemically. This entry focuses on the philosophically articulated views while indicating, where relevant, how they intersect with wider social and intellectual currents.

2. Definition and Scope of Moral Relativism

At its core, moral relativism is the thesis that the truth, correctness, or justification of moral judgments is relative to some parameter rather than absolute. Philosophers typically distinguish:

  • A truth-relativist strand: the proposition “X is wrong” is true or false only relative to a culture, individual, or appraiser.
  • A justification-relativist strand: whether one is justified in holding a moral belief depends on local standards of reasoning or evaluation.

Central Elements

Most definitions involve three components:

  1. Index: the thing to which morality is relative (e.g., cultures, individuals, evaluative frameworks).
  2. Relativized status: what is held to be relative (truth, justification, meaning, or all three).
  3. Non-universality claim: denial that the relevant moral status holds in a way that is independent of all indices.

A schematic contrast:

View typeWhat varies?What is denied?
Cultural relativismMoral truth across culturesSingle culture-transcendent moral truth
Individual relativismMoral truth across individualsShared interpersonal standard binding all individuals
Appraiser relativismTruth relative to appraisersTruth wholly independent of any assessor’s standards

Scope and Limits

Relativist theses can differ in scope:

  • Global relativism: all moral judgments are relative.
  • Local or partial relativism: only some domains (e.g., sexual morality, etiquette-like norms) are relative, while others (e.g., prohibitions on gratuitous cruelty) are treated as more robust.

There is also a distinction between descriptive claims about cultural diversity and normative or metaethical theses. Descriptive anthropological observations alone do not constitute moral relativism; relativism adds a claim about what moral truth or justification consists in.

Finally, many philosophers restrict the scope of “moral relativism” to views about moral evaluations, distinguishing them from relativism about aesthetics, rationality, or truth in general, even though the debates sometimes parallel one another.

3. The Core Question: Are Moral Judgments Objective?

Debates about moral relativism turn on whether moral judgments are objective. In metaethics, objectivity typically refers to the idea that some moral claims are true or false independently of any particular culture’s, individual’s, or group’s attitudes, and that they apply to agents whether or not those agents accept them.

Dimensions of Moral Objectivity

Philosophers analyze objectivity along several dimensions:

DimensionObjectivist claimRelativist challenge
TruthSome moral claims are stance-independent truths.Moral truth always depends on a standpoint or framework.
JustificationMoral beliefs can be justified by framework-neutral reasons.Justification is always internal to a culture or outlook.
AuthorityTrue moral norms are binding on all agents.Normative authority is limited to those sharing a standard.
ConvergenceIdeal reasoning would converge on the same moral truths.Different cultures/agents may reasonably diverge even ideally.

The core question can thus be framed as: Are there any moral truths or justified norms whose correctness does not depend on the particular standpoint from which they are assessed?

Competing Intuitions

Several common intuitions pull in opposing directions:

  • Objectivity intuitions: Many people treat certain moral condemnations (e.g., of genocide, torture, or slavery) as not merely expressions of local taste but as capturing how things really ought not to be.
  • Diversity and tolerance intuitions: Persistent and seemingly reasonable disagreement across cultures about family life, sexuality, authority, and distribution of resources suggests, to some, that moral standards are essentially plural and context-bound.

Moral relativism, in its various forms, answers the core question by insisting that truth, justification, or authority in morality cannot be fully detached from cultures, individuals, or evaluative perspectives, while objectivist and universalist theories answer by positing at least some standpoint-independent moral facts or norms.

4. Historical Origins and Ancient Precursors

Discussions resembling moral relativism appear early in Greek thought, often framed as conflicts between nomos (custom, law, convention) and physis (nature, what is by itself). Some thinkers emphasized the variability of customs and norms, while others defended the existence of natural or objective standards.

Early Greek Reflections

Herodotus, in Histories, famously recounts cultural differences, such as divergent burial practices, to illustrate the power of custom:

“Custom is king of all.”

— Herodotus, Histories 3.38

This observation has been read as a precursor to cultural relativism, though Herodotus does not explicitly deny objective morality.

The Sophists, active in 5th-century BCE Greece, often stressed how laws and moral codes arise from human agreement and differ across cities. Protagoras is reported to have claimed that “man is the measure of all things,” a saying later interpreted as a broad relativist thesis about truth and value, though its moral implications are debated.

Nomos vs. Physis

Contrasts between nomos and physis raised questions about whether justice and moral norms are conventional or grounded in nature:

Side of debateCharacterizationMoral implication
NomosHuman-made laws, customs, variable practicesMorality may be contingent and local
PhysisNature, what is independent of human arrangementsMorality may have objective natural basis

Some playwrights (e.g., Euripides) dramatized conflicts between divine or natural justice and local laws, highlighting tensions between relativist and objectivist intuitions.

Skeptical Tendencies

Ancient skepticism, later more fully developed by Pyrrhonian skeptics, also contributed proto-relativist themes by emphasizing disagreement (diaphonia) across cultures and schools and recommending suspension of judgment. While many skeptics stopped short of affirming relativism, their focus on intractable conflict about values laid an important groundwork for later relativist arguments based on moral diversity.

5. Ancient Approaches: Sophists, Skeptics, and Classical Critics

Ancient debates about morality contain positions that anticipate later discussions of relativism, as well as influential critiques.

Sophistic Conventionalism and Early Relativist Themes

Several Sophists advanced views that have been interpreted as moral conventionalism or relativism:

  • Protagoras purportedly held that what appears just to a city is just for that city, tying justice to communal belief.
  • Other Sophists highlighted the malleability of norms and argued that law serves the interests of the powerful, suggesting that morality lacks a fixed natural foundation.

These views typically emphasized practical rhetoric and persuasion over discovery of an independent moral truth, which later critics regarded as a slide toward relativism.

Skeptical Uses of Disagreement

Later Pyrrhonian Skeptics (e.g., Sextus Empiricus) systematically catalogued disagreements about customs and morals to argue for epochē (suspension of judgment). They maintained that equally strong arguments can be given on both sides of many moral questions.

Although Pyrrhonists did not straightforwardly endorse relativism, their methodology used persistent disagreement as evidence against confidently affirming objective moral truths, an argumentative strategy that reappears in modern relativist defenses.

Classical Critics: Plato and Aristotle

Plato criticized sophistic relativism in dialogues such as Protagoras and Republic. He argued that:

  • Justice and virtue have an objective structure tied to the Form of the Good.
  • Merely appealing to what a city happens to believe about justice confuses opinion with knowledge.

Aristotle, while recognizing variation in customs, proposed that there is a human function (ergon) and a natural standard of flourishing (eudaimonia), grounding ethics in a conception of human nature rather than convention alone. He allowed for some variability in application, but not for full-blown relativism.

FigureRelation to relativism
SophistsEmphasized convention; often seen as proto-relativists
Pyrrhonian SkepticsUsed disagreement to suspend moral judgment
PlatoDefended objective moral Forms
AristotleGrounded ethics in human nature and function

These ancient confrontations between conventionalist or skeptical tendencies and objectivist theories set many of the themes that later relativist and anti-relativist arguments would revisit.

6. Medieval Universalism and Religious Moral Objectivism

In the medieval period, major religious traditions—Christian, Islamic, and Jewish—developed moral theories that largely affirmed universal, objective moral norms, often tied to God’s will or to a divinely ordered nature. These views typically left little conceptual space for robust moral relativism, though they acknowledged cultural variation in secondary practices.

Divine Command and Natural Law

Christian thinkers such as Augustine and Thomas Aquinas held that morality is grounded in God:

  • Augustine emphasized obedience to divine law and linked moral error to turning away from God.
  • Aquinas articulated a natural law theory: human reason can discern basic moral precepts (e.g., preserve life, seek the good) that are universally binding because they reflect the eternal law.

Similar themes appear in Islamic and Jewish philosophy:

TraditionRepresentative figureKey moral idea
IslamicAl-GhazaliRight and wrong depend on God’s commands and wisdom
JewishMaimonides (often cited in this context)Rational grasp of commandments reflecting divine wisdom

Across these traditions, basic moral truths were taken to apply to all rational creatures, regardless of local custom.

Cultural Diversity within Universalism

Medieval thinkers recognized variation in positive law and custom but typically treated this as diversification within a universal moral framework. For instance:

  • Aquinas distinguished immutable primary precepts of natural law from more variable secondary precepts, which might admit of exceptions or cultural specificity.
  • Islamic jurists differentiated universal obligations from locally contingent rulings shaped by circumstances.

This allowed for some context-sensitivity without endorsing the idea that moral truth itself is relative to culture.

Attitudes toward Relativist Tendencies

When confronted with divergent moral practices in other societies or among nonbelievers, medieval authors often interpreted them as:

  • Errors due to ignorance or corruption of reason.
  • Partial grasps of natural or divine law.

Thus, while medieval moral thought did not generally articulate moral relativism, it contributed a strongly universalist and objectivist background against which early modern and modern relativist ideas would later define themselves.

7. Early Modern Subjectivism and the Road to Relativism

Early modern philosophy (17th–18th centuries) introduced influential accounts of morality that centered on human attitudes, sentiments, or rational structures, which some later interpreters see as paving the way to moral relativism, even when the authors themselves remained universalists.

Sentimentalism and Moral Sense Theories

Thinkers such as David Hume and Francis Hutcheson argued that moral distinctions depend on human feelings:

  • Hume held that morality is rooted in sentiment—feelings of approval and disapproval—rather than in reason alone.
  • Moral approval often tracks sympathy and social utility, suggesting a psychological rather than metaphysical grounding.

These views do not straightforwardly endorse relativism, since they often assume that human nature is broadly shared, but they shift attention from objective moral facts to subject-dependent responses, which later philosophers would interpret in relativist directions.

Subjectivist and Contractarian Tendencies

Some early moderns linked morality to human preferences and agreements:

  • Thomas Hobbes treated moral norms as arising from covenants among individuals seeking peace and security, relative to their interests in the state of nature.
  • Social contract theories more broadly framed right and obligation in terms of what rational agents would agree to under certain conditions, leaving open questions about cross-cultural convergence.

At the same time, Immanuel Kant reacted against sentimentalism by defending a universal moral law grounded in rational autonomy. His categorical imperative is meant to apply to all rational beings, exemplifying a strong form of moral objectivism.

Emerging Historicism and Cultural Awareness

Late Enlightenment and Romantic thinkers, along with early 19th-century historicists, emphasized the historical and cultural embeddedness of norms:

  • Values were increasingly seen as evolving with social conditions and collective self-understandings.
  • This historicist sensibility, while not always relativist, challenged the idea of timeless, static moral codes.
TrendContribution toward relativism
SentimentalismGrounds morality in variable human feelings
ContractarianismTies norms to agreements among particular agents
HistoricismStresses historical contingency of moral outlooks

These developments collectively prepared the intellectual terrain for more explicit forms of moral relativism in late 19th- and 20th-century thought.

8. Anthropology, Historicism, and the Rise of Cultural Relativism

Explicit cultural moral relativism emerged most prominently in late 19th- and early 20th-century anthropology and sociology, in reaction to earlier ethnocentric and evolutionist accounts of “primitive” societies.

Anthropological Cultural Relativism

Anthropologists such as Franz Boas, Ruth Benedict, and Margaret Mead argued that:

  • Moral norms and values are deeply embedded in the symbolic systems, social structures, and historical experiences of particular cultures.
  • Practices judged “immoral” from a Western standpoint (e.g., certain marriage customs, rites of passage) may be intelligible, even necessary, within their own cultural contexts.

Boas advocated methodological cultural relativism: anthropologists should suspend their own moral judgments to understand cultures on their own terms. Benedict famously wrote that morality is “a convenience of social living,” varying with cultural patterns.

Historicism and Sociological Approaches

In parallel, historicist thinkers and sociologists highlighted the historical contingency of moral codes:

  • Historicism, in figures influenced by Hegelian and post-Hegelian thought, emphasized that institutions and values develop over time and cannot be evaluated outside their historical contexts.
  • Sociologists such as Émile Durkheim treated moral norms as social facts emerging from collective life, differing across societies while serving integrative functions.
DisciplineKey themeImpact on moral theory
AnthropologyThick description of local normsUndermined assumptions of universal standards
SociologyMorality as social integrationLinked right/wrong to social roles and needs
HistoricismValues as historically situatedChallenged timelessness of moral codes

From Descriptive to Normative Relativism

While many anthropologists initially advanced descriptive claims about moral diversity, their work was often interpreted, by philosophers and the public, as support for normative or metaethical relativism:

  • If moral codes vary deeply and are functional or coherent within their own contexts, some inferred that no single moral system can claim objective superiority.
  • Others used cultural relativism to challenge colonial and missionary claims of moral progress or civilizing missions.

These developments fed directly into 20th-century philosophical articulations of cultural relativism and shaped ongoing debates about ethnocentrism, tolerance, and the possibility of cross-cultural moral criticism.

9. Major Forms of Moral Relativism

Philosophers distinguish several major forms of moral relativism, depending on what moral judgments are taken to be relative to.

Cultural (Societal) Relativism

Cultural relativism holds that the truth or justification of moral judgments is relative to the norms, practices, or basic values of a particular culture or society. On this view:

  • “X is wrong” means roughly “X is forbidden by my (or our) culture’s moral code.”
  • There is no single culture-transcendent standard by which all moral codes can be ranked as closer to or further from the moral truth.

Cultural relativism often draws on anthropological evidence of cross-cultural diversity in moral beliefs and practices.

Individual (Subjective) Relativism

Individual relativism (or subjective relativism) ties moral truth to individual attitudes or commitments:

  • A statement like “Stealing is wrong” is true-for-A if A disapproves of stealing, and may be false-for-B if B approves.
  • Moral correctness is fixed by each person’s standards, making interpersonal moral disagreement more a clash of attitudes than a contest over a shared truth.

Subjective relativism is sometimes associated with strong moral autonomy but raises questions about shared norms and interpersonal criticism.

Appraiser (Speaker or Context) Relativism

Appraiser relativism holds that the truth of a moral judgment is relative not to the agent acting, but to the person making or assessing the claim:

  • The same utterance “X is wrong” could be true relative to one assessor’s standards and false relative to another’s.
  • Contemporary semantic theories model moral predicates as expressing properties that are only truth-evaluable relative to an assessor’s parameter (e.g., a standard of value).

This form seeks to capture phenomena such as faultless disagreement in moral discourse.

Comparative Overview

FormRelativized to…Typical focus
Cultural relativismSocietal norms/valuesCross-cultural disagreement and critique
Individual relativismPersonal attitudes/standardsMoral autonomy and interpersonal conflict
Appraiser relativismAssessor’s evaluative systemSemantics of moral language

These forms are not mutually exclusive; some theories combine cultural and appraiser elements or endorse relativism about justification but not about truth.

10. Arguments for Moral Relativism

Philosophers and social scientists have advanced several influential lines of argument in support of moral relativism, often targeting the plausibility of strong moral objectivism.

Argument from Moral Diversity

One central argument appeals to persistent cross-cultural and historical moral disagreement:

  • Different societies endorse divergent norms on issues such as polygamy, hierarchy, punishment, and sexual behavior.
  • Disagreement often persists even under increased information and reflection.

Proponents contend that such diversity is better explained if moral truth (or justification) is relative to cultures or frameworks, rather than if there is a single objective morality to which all are answerable.

Anti-Ethnocentrism and Tolerance

Another influential consideration is the desire to avoid ethnocentrism—judging other cultures solely by one’s own standards:

  • Relativism is said to encourage tolerance and humility, by recognizing that one’s moral code is not the uniquely correct one.
  • It purportedly guards against using claims of universal morality to rationalize imperialism, cultural domination, or missionary imposition.

On this view, relativism offers an ethical posture of respect towards difference.

Explanatory and Naturalistic Arguments

Relativists also stress the explanatory role of social and psychological factors:

  • Historical, economic, and ecological conditions can be used to explain why societies adopt particular norms (e.g., about property, kinship, or violence).
  • If such explanations suffice, some argue that postulating objective moral facts becomes unnecessary.

In addition, evolutionary and game-theoretic models suggest multiple stable strategies (e.g., various cooperation norms) can evolve, supporting the idea of plural viable moral frameworks rather than a single correct one.

Epistemic Humility

Finally, some defenses emphasize epistemic limitations:

  • Human beings are historically situated, often mistaken, and influenced by local biases.
  • Given this, it is claimed to be more reasonable to treat moral convictions as framework-bound rather than as glimpses of a fully objective moral order.

Together, these arguments aim to show that relativist accounts better fit the empirical and epistemic realities of moral life than robust objectivism does.

11. Arguments Against Moral Relativism

Critics of moral relativism advance a range of objections, challenging both its coherence and its fit with moral practice.

Self-Refutation and Normative Incoherence

One influential worry targets relativism’s alleged self-refuting implications:

  • If relativists praise tolerance as a universal virtue, they appear to contradict their own denial of universal values.
  • If tolerance is only relatively good (e.g., good in liberal cultures), then relativism seems unable to criticize intolerant societies in any robust sense.

Some philosophers argue that relativism either smuggles in universal norms or must accept that no culture’s practices, however oppressive, can be condemned as wrong simpliciter.

Moral Reform and Criticism

Another line of objection focuses on moral reformers and internal criticism:

  • Movements against slavery, colonialism, or gender discrimination initially often opposed the dominant norms of their own societies.
  • If what is right is defined by prevailing cultural norms, early reformers must be judged morally wrong (by their own culture’s standards), even when later generations view them as pioneers of progress.

Critics contend that relativism struggles to make sense of moral progress or principled internal dissent.

Moral Equivalence and Atrocities

Relativism appears, to some, to entail a troubling moral equivalence:

  • If each culture’s norms determine what is “right for it,” then a society endorsing genocide or systematic oppression is as right (for itself) as any other.
  • This seems to conflict with widely held intuitions that certain actions are wrong regardless of cultural endorsement.

Objectivists use such cases to argue that at least some non-relative moral constraints are necessary.

Practical and Conceptual Concerns

Additional objections include:

  • Collapse of disagreement: If each party’s moral claims are true relative to their own standards, genuine disagreement about how things ought to be may seem illusory or purely verbal.
  • Vagueness of “culture” or “framework”: Given internal diversity and overlapping identities, it may be unclear which culture’s norms fix moral truth.
  • Normative guidance: In hard conflicts between frameworks (e.g., international disputes), relativism may offer insufficient guidance about what to do.

These criticisms motivate objectivist and pluralist alternatives that seek to preserve some form of standpoint-independent moral assessment while acknowledging diversity.

12. Relativism, Moral Disagreement, and Faultless Disagreement

Moral disagreement plays a central role in debates about relativism. Different theories interpret the nature and implications of such disagreement in contrasting ways.

Types of Moral Disagreement

Disputes about morality can arise:

  • Within a culture (e.g., over abortion or capital punishment).
  • Across cultures (e.g., about arranged marriage or blasphemy laws).
  • Across time (e.g., shifting views on slavery or gender roles).

Some disagreements may turn on empirical facts, but others persist even when factual disagreements are resolved.

Relativist Interpretations

Relativists often treat persistent disagreement as evidence that:

  • Moral claims are indexed to different standards or frameworks, so that each side’s judgments can be true relative to their own standpoint.
  • The aim of moral discourse is not convergence on a single objective truth but negotiation or expression of values.

On this view, many apparent conflicts are really cases where parties talk past each other because they employ different moral parameters.

Faultless Disagreement

The notion of faultless disagreement has become prominent in discussions of relativist semantics. It involves cases where:

  • Two speakers make contradictory moral claims (e.g., “Abortion is wrong” / “Abortion is not wrong”).
  • Intuitively, neither seems mistaken or irrational given their own standards.

Appraiser relativists argue that this can be modeled by allowing the truth of moral sentences to be relative to the assessor’s evaluative standards. Thus:

SpeakerUtteranceTrue relative to…
A“Abortion is wrong.”A’s standards
B“Abortion is not wrong.”B’s standards

Critics respond that what appears to be faultless disagreement might instead involve:

  • Different concepts or contexts.
  • Underdetermined evidence.
  • Or that genuine disagreement requires a shared standard to which both parties appeal, favoring objectivist or non-relativist accounts.

How to interpret the structure and phenomenology of moral disagreement thus remains central to assessing the plausibility of relativist positions.

13. Relativism in Moral Semantics and Metaethics

Recent philosophical work has developed sophisticated forms of semantic relativism for moral language, linking questions about truth conditions to broader metaethical debates.

Semantic Theories of Relative Truth

In semantic relativism, the truth of a sentence like “Lying is wrong” is evaluated relative to an additional parameter—such as an assessor’s moral standard—beyond the context of utterance. Pioneering work by theorists like John MacFarlane (though focused also on other domains) has inspired analogous approaches to moral discourse.

Key features include:

  • Index-dependence: Moral predicates denote properties that are only determinately instantiated relative to a standard.
  • Assessment sensitivity: The truth-value of an utterance can vary with the context of assessment, allowing for faultless disagreement.

Relation to Metaethical Positions

Semantic relativism interacts with metaethical views in complex ways:

Metaethical stanceTypical semantic correlateRelation to relativism
Moral realismContext-invariant truth conditionsOften resists relativized truth
ExpressivismMoral sentences express attitudesCan be combined with relativist assessment of attitudes
NoncognitivismDenies truth-aptness of moral claimsSometimes sidesteps truth-relativist frameworks
Appraiser relativismTruth relative to appraiser standardsOffers a form of cognitivist relativism

Some philosophers, such as Gilbert Harman and David Wong, argue that moral truths are framework-relative but still truth-apt, situating their views between robust realism and noncognitivism.

Motivations and Challenges

Proponents claim that relativist semantics:

  • Better captures certain linguistic data (e.g., retraction practices, disagreement across contexts).
  • Respects the intuitive disagreement in moral debates while allowing each party to speak truthfully relative to their standards.

Critics question whether:

  • Apparent relativist phenomena can be explained instead by pragmatics, ambiguity, or incomplete information.
  • Semantic relativism can supply the normative force of moral claims if truth is always tied to an assessor’s standards.

Thus, debates about relativism in semantics intersect with broader questions about the nature of moral truth, the function of moral discourse, and the sources of normativity.

14. Interdisciplinary Perspectives: Science, Religion, and Politics

Moral relativism interacts with findings and debates in several other disciplines, shaping and being shaped by them.

Science: Anthropology, Psychology, and Evolution

Empirical research informs relativist and anti-relativist arguments:

  • Anthropology and sociology document wide variation in norms, often interpreted as supporting cultural relativism or, at minimum, cautioning against naive universalism.
  • Cognitive science and moral psychology identify recurring patterns—such as concerns with harm, fairness, loyalty, authority, and purity—that some interpret as evidence for partial moral universals beneath surface diversity.
  • Evolutionary theory and game-theoretic models show how different cooperative strategies can be stable in varying environments, suggesting a pluralism of viable moral systems.

These disciplines contribute data that philosophers use both to motivate relativism and to argue for constrained forms of objectivity.

Religion: Universal Claims and Internal Diversity

Religious traditions often advance universal moral teachings grounded in divine command, revelation, or natural law and therefore typically criticize relativism as undermining sin, virtue, and religious authority.

At the same time:

  • Comparative religion reveals substantial plurality among religious moral codes.
  • Within religions, debates arise over which norms are timeless (e.g., compassion, justice) and which are historically or culturally conditioned (e.g., dress codes, dietary rules).

Some theologians endorse limited relativism about secondary norms while maintaining universal core principles, generating nuanced internal positions.

Politics: Sovereignty, Human Rights, and Multiculturalism

In political theory and international relations, moral relativism informs controversies over:

  • Cultural sovereignty and non-intervention: Relativist arguments are sometimes invoked to resist external criticism of domestic practices.
  • Human rights: Universal human rights frameworks presuppose some cross-cultural moral standards; critics from relativist or communitarian perspectives question whether such norms are culturally biased.
  • Multiculturalism and identity politics: Within plural societies, policymakers grapple with accommodating divergent moral outlooks (e.g., on family law, expression, and gender roles) without collapsing into either enforced uniformity or unmanageable relativism.
DomainRelativist emphasisObjectivist response
ScienceDiversity of moral codesEvidence for underlying universals
ReligionContextual interpretation of some normsAppeal to core, universal divine or natural law
PoliticsRespect for cultural difference, anti-imperialismDefense of universal rights and liberal principles

These interdisciplinary engagements ensure that philosophical debates about moral relativism remain closely connected to practical and empirical concerns.

15. Critiques, Alternatives, and Moderate Pluralist Views

Responses to moral relativism include not only straightforward defenses of objectivism but also intermediate positions that seek to accommodate diversity without embracing full relativism.

Critiques of Strong Relativism

Beyond objections surveyed earlier, critics argue that strong relativism:

  • Undermines cross-cultural dialogue, since there is no shared standard for evaluating conflicting claims.
  • Risks normative paralysis in responding to practices widely regarded as unjust.
  • May be unstable, as it seems to rely on universal norms of respect or non-imposition that it officially denies.

These concerns motivate alternatives that recognize diversity while retaining some evaluative foothold.

Moral Pluralism

Moral pluralism maintains that there are multiple genuine values or moral principles that can conflict without being reducible to a single master value. Pluralists such as Isaiah Berlin or W.D. Ross (often cited in this context) argue that:

  • Values like autonomy, equality, loyalty, and beneficence can be incommensurable yet all real.
  • Different societies may legitimately prioritize values differently, yielding diverse but not wholly arbitrary moral systems.

Pluralism can be combined with a constrained objectivism, according to which not all value orderings are acceptable, even if more than one is reasonable.

Relativized or Contextualized Objectivism

Some theorists propose relativized objectivism, holding that:

  • Moral truths are objective within a certain range of human forms of life, needs, or rational capacities.
  • Context (e.g., social structure, technological conditions) shapes which norms apply, but evaluation is not simply “anything goes.”

For example, norms about property or family structure might justifiably differ across contexts, while prohibitions on gratuitous cruelty or severe oppression are treated as robustly wrong across human societies.

PositionDiversity acknowledgedObjectivity retained?
Strong relativismHighNo, or only framework-relative
Moral pluralismHighYes, multiple genuine values
Relativized objectivismModerate–highYes, indexed to human needs or forms of life

These moderate views attempt to capture insights of relativism—especially about diversity and contextuality—while preserving some shared standards for critique, dialogue, and cooperation.

16. Practical Implications for Tolerance and Human Rights

Moral relativism has been closely linked, in public debates, to questions about tolerance, cultural respect, and the status of human rights. Philosophers examine whether and how relativist or objectivist views support these practical commitments.

Tolerance and Cultural Respect

Advocates of relativism often claim that:

  • Recognizing moral codes as culture-bound fosters tolerance and discourages judgmental attitudes toward unfamiliar practices.
  • It can help counter ethnocentric or imperialistic tendencies in international relations and cross-cultural engagement.

However, critics argue that:

  • Relativism does not uniquely support tolerance; an objectivist might defend tolerance as a universal value.
  • If all norms are relative, relativism may also license intolerance where a culture endorses it, weakening principled opposition to persecution or discrimination.

Human Rights Debates

International human rights regimes presuppose certain universal entitlements (e.g., to life, liberty, non-discrimination). Relativist and anti-relativist positions intersect here:

  • Relativist critiques question whether human rights reflect Western liberal assumptions, suggesting that insisting on them everywhere may amount to cultural imposition.
  • Universalist defenses maintain that core human rights protect basic interests or dignities shared by all humans, irrespective of local endorsement.

Some theorists advocate “thin” universalism: a minimal set of rights and protections that gain broad cross-cultural support, while allowing extensive room for local variation in how they are implemented.

Within multicultural states, questions arise about:

  • How legal systems should treat practices such as religious dress, customary law, or family arrangements.
  • Whether courts should defer to community norms or uphold uniform rights-based standards.
IssueRelativist-friendly approachUniversalist-friendly approach
Cultural practicesDefer to local/community norms where possibleRestrict practices that violate basic rights
ToleranceValue coexistence of diverse moral codesValue respect, but within a rights-based framework
Human rightsEmphasize negotiation and cultural adaptationEmphasize universality and non-derogable protections

Philosophical positions on relativism thus inform, and are tested by, practical decisions about cultural accommodation, legal pluralism, and global norms.

17. Legacy and Historical Significance of Moral Relativism

Moral relativism has played a significant role in modern intellectual history, influencing how societies understand morality, culture, and progress.

Shaping Self-Understanding in Modernity

The recognition of deep cultural and historical diversity in moral codes has contributed to a modern sense of:

  • Reflexivity: awareness that one’s own values are historically situated and open to challenge.
  • Critical distance from inherited norms, fostering both skepticism and creativity in moral thought.

Relativist themes have been prominent in debates over colonialism, modernization, and globalization, often informing critiques of claims to civilizational superiority.

Influence on Philosophical and Social Theory

Relativism’s presence has prompted:

  • The development of more nuanced metaethical theories (e.g., pluralism, constructivism, relativized objectivism) that take diversity seriously without endorsing wholesale relativism.
  • Ongoing examination of disagreement, context, and interpretation in hermeneutics, critical theory, and post-structuralism, where ideas about the contingency of norms and frameworks are central.

Even staunch critics have acknowledged relativism’s importance as a challenge that objectivist theories must address.

Continuing Controversies

In public discourse, “relativism” is often invoked:

  • As a criticism, suggesting moral laxity or the erosion of shared standards.
  • As a defensive label, signaling resistance to moralizing interventions in cultural or personal life.
AspectHistorical significance
Anthropology and sociologyHelped displace evolutionist and ethnocentric models
Political thoughtInformed debates on sovereignty and intervention
Moral philosophyForced re-examination of objectivity and universality

The enduring legacy of moral relativism lies less in a settled doctrine than in the persistent questions it raises about the nature of moral truth, the legitimacy of cross-cultural judgment, and the balance between respect for diversity and commitment to shared norms.

Study Guide

Key Concepts

Moral relativism

The view that the truth, correctness, or justification of moral judgments depends on, or is relative to, specific cultures, individuals, or evaluative frameworks rather than being universally and absolutely valid.

Metaethics

The branch of ethics that investigates the nature, status, and meaning of moral judgments, including whether they can be true or false and what it would be for them to be objective or relative.

Cultural relativism

A form of moral relativism holding that moral truth or justification is determined by the norms, values, or practices of a particular culture or society.

Individual (subjective) relativism

The view that moral truth or rightness is relative to each individual’s personal attitudes, commitments, or standards.

Appraiser relativism and relativized truth

The view that the truth of a moral judgment is relative to the standards of the person making or assessing the judgment, modeled through a notion of truth that is defined relative to an assessor’s evaluative parameter.

Moral objectivism / universalism

The opposing position that at least some moral truths hold independently of any particular culture, individual, or perspective and are valid for all persons.

Moral disagreement and faultless disagreement

Moral disagreement is conflict between agents or groups over moral claims; faultless disagreement is a special kind where opposing judgments both seem, in some sense, not in error, often motivating relativist semantics.

Moral pluralism and relativized objectivism

Intermediate views that recognize multiple, sometimes incompatible but nonetheless reasonable moral frameworks or values, and often treat objectivity as indexed to human needs, forms of life, or shared rationality rather than as absolute.

Discussion Questions
Q1

How does the distinction between descriptive cultural diversity and metaethical moral relativism help clarify what is really at stake in debates about relativism?

Q2

To what extent does the historical evidence of moral change and reform (e.g., abolitionism, feminism) support moral objectivism rather than relativism?

Q3

Is cultural relativism compatible with taking internal moral reformers (e.g., early critics of slavery in a slave-owning society) to be morally admirable at the time they dissent? Why or why not?

Q4

What is ‘faultless disagreement’ in moral discourse, and how does appraiser relativism attempt to account for it? Do you find this explanation convincing?

Q5

Can a moderate moral pluralism or relativized objectivism preserve the insights of relativism (about diversity and context) while avoiding its most serious problems (e.g., moral equivalence of atrocities)?

Q6

How should international human rights regimes respond to claims of cultural relativism from states or communities that reject certain rights as ‘Western’? On what philosophical grounds could they justify either insisting on or revising those norms?

Q7

In everyday moral conversation, do you think people talk more like objectivists or relativists? Provide examples and explain how different semantic or metaethical theories would interpret them.
