Herodotus: 'custom is king'
The historian records how different peoples find each other's funeral customs appalling, concluding that custom rules how each society sees right and wrong.
Customs that horrify one society are sacred in another. Is morality universal, or just local custom? The relativism debate is ancient โ and the honest answer is messier than either side admits.

Travel far enough, in space or time, and the moral map redraws itself. What one society treats as duty, another treats as crime; what one century burned people for, the next celebrates. Faced with this, a natural thought arrives: maybe right and wrong are not fixed at all โ maybe they are just whatever each culture happens to say they are. That thought has a name: moral relativism.
It is one of the oldest questions in ethics, and it cuts both ways. If morality is purely local custom, then no outsider can ever call any practice wrong โ not slavery, not cruelty, nothing. But if morality is one fixed code for all, whose code is it, and how do we know it isn't just one culture dressing up its habits as universal law?
The honest position is that neither extreme survives scrutiny intact โ and seeing why is more useful than picking a team.
The puzzle is at least as old as the first people who travelled and compared notes. The Greek historian Herodotus, writing in the 5th century BCE, told of the Persian king Darius asking one group how much they would take to burn their dead, and another how much to eat them โ each recoiling in horror at the other's custom. His conclusion, quoting a poet, was that 'custom is king of all'.
Around the same time the Sophist Protagoras offered the sharpest early slogan: 'Man is the measure of all things.' If each person, or each community, is the yardstick, then truth and value bend to the measurer. Plato spent considerable effort arguing against exactly this, insisting that justice and goodness must be more than local opinion or they would mean nothing at all.
So the two camps were drawn early. On one side, the observation that moral codes plainly differ across societies. On the other, the worry that if difference is all there is, then 'wrong' loses its teeth. Every later round of the debate โ and there have been many โ is a refinement of this ancient standoff between observed variety and the demand for a shared standard.

'I did something bad' and 'I am bad' feel similar at 2am, but they are different emotions โ guilt and shame โ and decades of research find they pull your behaviour in opposite directions.
'Find your one true purpose' has become a quiet source of dread. Existentialism offers a release: there is no purpose waiting to be discovered โ you are the one who makes it, again and again.
Many Indians carry a quiet guilt that wanting money makes them less spiritual. But the tradition itself lists artha โ wealth and security โ as one of the four legitimate aims of a human life.
'India was always religious' is half the story. Materialist, god-denying schools like Charvaka were born here, argued openly for centuries, and made doubt as Indian as devotion.
We say 'wash away your paap' as if God keeps a ledger you can pay off. But papa and punya aren't a debt to a deity โ they're the natural result of what you do: physics, not a courtroom.
'I tried meditating but couldn't stop thinking' is the most common reason people quit โ and it rests on a myth. Stopping thought was never the goal. Noticing it, without getting dragged along, is.
Much of the heat in this debate comes from blurring two very different claims. Pull them apart and the picture clarifies.
| Position | What it actually says | The usual objection |
|---|---|---|
| Descriptive relativism | As a fact, moral codes differ across cultures | True, but it alone settles nothing |
| Normative relativism | Therefore each code is equally valid; no outside judgement allowed | Then no one could condemn atrocity |
| Universalism | Some moral truths hold for everyone | Whose? Risk of cultural arrogance |
The anthropologist Ruth Benedict, in the 1930s, gathered striking evidence that what counts as normal or moral varies enormously between societies โ a powerful case for descriptive relativism. But the philosopher James Rachels later pressed the key point: that cultures differ does not by itself prove that none is closer to right. People once differed on whether the earth was flat; the disagreement did not make both views equally true. Most philosophers today therefore reject crude relativism without swinging to crude absolutism โ holding that there is likely a thin universal floor (against gratuitous cruelty, say) with a great deal of legitimate cultural variation built above it.
The word gets used loosely; three corrections help.
The same standoff now runs through some of the loudest arguments of our time, usually without anyone naming the philosophy underneath.
The twentieth century pushed both sides to their limits. The horrors of mid-century made many insist on universal human rights โ a floor below which no culture's customs could be excused, written into declarations meant to bind everyone. Yet critics fairly asked whose values those universals encoded, and whether 'universal' sometimes meant 'Western, exported'. India knows both pulls intimately: it abolished practices once defended as tradition while also resisting outside lectures about its own ways. There is no neat formula here. What the long history offers is not an answer key but a better way to argue โ distinguishing a thin, defensible universal floor from the rich, legitimate diversity that should sit above it.
This is not a seminar game. How you answer it shapes whether you can criticise a custom you were raised inside, whether you can defend a stranger's rights across a cultural line, and whether you believe your society can improve at all. Lean too far into relativism and you lose the standing to condemn anything; lean too far into absolutism and you risk mistaking your own habits for the laws of the universe.
The deeper lesson is that the useful position is also the most demanding one. It asks you to hold two truths at once: that much of morality really is shaped by culture and history, and that not every practice is therefore beyond criticism. That means doing the hard work case by case โ asking which of your certainties are local custom and which rest on something more defensible, and extending the same scrutiny to others rather than either judging reflexively or excusing everything.
The thing worth keeping is intellectual humility without paralysis. You can take cultural difference seriously and still believe that cruelty is wrong wherever it happens. Understood that way, the relativism question is not a trap to escape but a discipline to practise โ and a society that argues about it honestly is, in that very act, taking its own moral future seriously.

Philosopher James Rachels argues that cultures differing on morality does not prove all are equally right, undercutting crude normative relativism.
