This lesson contains the hardest genuine dilemma in Part 2. Most of the concepts so far have been instruments. This one is a fork in the road, and both paths have a cliff.
Read it slowly. And notice that it does not end with a comfortable resolution, because there is not one available.
The idea, in plain words
Note carefully what cultural relativism was originally: a research method, not a moral doctrine. It says: understand before judging. Whether it also says never judge is precisely the argument, and the two claims must be kept apart. We will call them methodological relativism and moral relativism, and the entire second half of this lesson depends on that distinction.
Ethnocentrism: not merely rudeness, but bad data
William Graham Sumner — the same 1906 book that gave us folkways (2.1.3) — coined the term. His account: each group takes itself as the centre, regards its own folkways as the only right ones, and looks with contempt on outsiders.
The reason this matters for sociology is not politeness. It is that ethnocentrism produces systematically wrong descriptions, and wrong descriptions produce wrong explanations and disastrous policy.
Four characteristic distortions:
Misreading function. A practice is described as irrational because the observer does not know what it accomplishes. Elaborate food rules look arbitrary until you know what they regulate. The village patron–client exchange of services — the jajmani system (6.2.9) — looks like inefficiency to someone who has not noticed it is an insurance arrangement.
Reading absence as deficiency. A society without a written constitution is described as having no law; a society without a market in land as having no property. It has different law and different property.
Inferring inferiority from difference. The whole nineteenth-century apparatus of "stages of civilisation" (3.3, 1.2.3, 1.4.3) rested on this move, and it produced a century of confident, wrong social science with real political consequences.
The double standard. Our violence is order; theirs is savagery. Our arranged introductions are networking; theirs are backward. Our inherited advantage is family; theirs is nepotism.
And the sharpest version of the critique is Edward Said's Orientalism (6.7): not merely that Western scholarship misdescribed the East, but that it produced an image of "the Orient" — sensual, despotic, static, irrational — that functioned as the West's flattering mirror and as a justification for ruling it. Ethnocentrism, in Said's account, is not a personal failing but an organised body of knowledge with institutions, careers and archives.
Note also that ethnocentrism is not a Western monopoly. Every group is prone to it, and the sociologically interesting cases are internal: caste contempt, regional chauvinism, urban descriptions of rural life, elite descriptions of the poor. Sumner's insight was general.
Cultural relativism: what it actually gets you
Relativism as a method is one of the great achievements of the human sciences, and it delivers three things.
Accurate description. You cannot describe a practice correctly until you know what it means to those doing it. This is Weber's verstehen (1.3.3, 4.3) applied to whole ways of life.
The denaturalising effect. Understanding another arrangement is the fastest available route to seeing your own as arbitrary (1.1.2). Relativism is therefore not merely generosity towards others; it is the instrument for studying yourself.
Protection against the double standard. Once you insist on symmetry — describing your own practices in the same vocabulary you use for others — a great deal of confident nonsense becomes visible. Miner's Nacirema (1.1.2) is this insistence turned into a joke.
Franz Boas and the tradition he founded in American anthropology made this central, in direct opposition to the ranked "stages" model then dominant. It is one of the clearest cases in intellectual history of a methodological rule improving both the science and the ethics of a field at once.
Go deeper
The three problems with moral relativism
Methodological relativism is nearly unarguable. Moral relativism — the claim that no cross-cultural evaluation is legitimate because standards are internal to cultures — has three serious problems, and you should be able to state them.
One: cultures are not unanimous, so "their values" is a claim, not a fact. This is the most important objection and it follows directly from 2.1.7. Every society contains dissenters, reformers, and people who bear the cost of a practice and say so. When an outsider defers to "the culture's view," which view are they deferring to? Almost always the view of those with the authority to speak for the whole — which means moral relativism, applied naively, functions as a defence of internal power. Phule and Ambedkar were not outsiders to Indian society. Nor were the women's movements in any country.
Two: it is self-undermining. If all standards are culturally internal, then so is the standard of tolerance being urged, and it has no claim on anyone outside the culture that holds it. Consistent moral relativism cannot recommend tolerance; it can only report that some people value it.
Three: it makes solidarity unintelligible. It implies that no one can legitimately object to anything happening to anyone in a group other than their own — which would delegitimise most of the moral progress of the last two centuries, including abolition and the international human rights framework, and which sits very oddly with the fact that appeals across cultures have been how the oppressed have often found allies.
And the three problems with universalism
Fairness requires the other column, because the universalist position has failure modes just as serious.
One: universal standards have a habit of being local standards in a good suit. The historical record here is bad. "Civilisation," "development," "modernisation," "human rights" have each been used at some point to justify conquest, dispossession or coercion — the "civilising mission" and the "white man's burden" were universalist arguments (3.2, 6.7).
Two: it is selectively applied. Objections to another society's treatment of women, minorities or workers are frequently raised by states with poor records on the same, and against adversaries rather than allies. Selective universalism is a political instrument, and everyone on the receiving end can see it.
Three: it disables understanding. If you already know the practice is wrong, you will not do the work of finding out what it is, and you will therefore be ineffective at changing it. The reformer who understands least intervenes worst.
A workable position
Here is a defensible way to hold both, and it is roughly where most careful sociologists end up.
Separate the two operations, and always do them in this order. First, understand the practice as thoroughly as possible on its own terms — its meaning, its history, its function, who defends it and why. This is methodological relativism and it is not optional. Second, evaluate if you are going to, and do so explicitly, with your criteria stated, so they can be argued with.
Take internal dissent as your guide. Instead of asking "what does their culture say?", ask "who inside this arrangement bears its costs, and what do they say?" This single reframing dissolves most of the apparent dilemma, because it stops treating culture as a unanimous subject and starts treating it as a field of positions (2.1.7). It is also, incidentally, what standpoint theory recommends (7.1) and what participatory research does in practice (7.6).
Prefer criteria that travel. Some evaluative standards are less parochial than others because they concern conditions people in very different arrangements can recognise: whether a person can leave; whether they consented and could have refused without ruin; whether they have information; whether the harm is reversible; whether the burden falls on those with least power. Sen's capabilities framework (8.8) is one attempt to formalise this, and note the point of his approach — it asks what people are able to do and be, rather than prescribing what they should choose.
Be symmetrical. Apply the same criteria to your own society, and expect to find failures. A reformer who has never turned the lens homeward is not a universalist; they are an ethnocentrist with a vocabulary.
And distinguish describing, judging and intervening. They are three different acts with three different burdens of proof. You can accurately describe a practice, privately judge it, and still have no standing or competence to intervene in it. Collapsing the three is where most of the bad behaviour in this area comes from.
Why it matters
It is the discipline's central methodological commitment. Everything you will read in Part 6 — Indian, Latin American, African, Chinese and Islamic sociologies — exists because the discipline eventually took this lesson seriously about itself. Relativism as a method is what made a global sociology possible.
It is a live problem in every applied field. Public health, development, education, law, social work and journalism all require someone to decide when to defer to local practice and when not to. The programmes that fail are usually the ones that skipped the first operation.
And it is a personal tool. Applied inwards, this lesson is what makes 1.1.2's habit possible: you can only see your own arrangements as arbitrary by taking someone else's seriously. Ethnocentrism is not only unjust to others; it is the main thing standing between you and understanding yourself.
