The Challenge of Cultural Relativism: James Rachels on Morality Beyond Culture
Imagine you're traveling in a country where eating dogs is considered perfectly normal, while in your home culture it's unthinkable. Still, or consider a society that practices female genital mutilation, viewing it as a sacred tradition. Because of that, what's your instinctive reaction? Most of us would say these practices are wrong, period. But cultural relativism — the idea that moral truths depend entirely on what a culture accepts — pushes back against that gut reaction. It says you can't judge another culture by your own standards.
James Rachels, the late philosopher, took on this idea headfirst. Day to day, he didn't just critique cultural relativism from an academic distance — he showed why it matters, why it fails, and why we need a different approach to ethics. Here's the thing: if Rachels was right, then the whole project of moral progress — of saying slavery was wrong even when societies accepted it — becomes impossible. That's a high stakes game.
Worth pausing on this one.
What Is Cultural Relativism?
At its core, cultural relativism is the claim that there are no objective moral truths — only the moral codes that different societies happen to adopt. What's right in one culture might be wrong in another, and neither side can claim superiority. Because of that, the famous anthropologist Ruth Benedict put it bluntly: "Right and wrong have no absolute validity. They are all compounds of a given climate of group co-operation And that's really what it comes down to..
This isn't just an abstract theory. It had real influence in anthropology and beyond. The idea was supposed to promote tolerance — don't judge other cultures by your own standards. But Rachels pointed out a fatal flaw: if you take cultural relativism seriously, you end up in some very uncomfortable places.
The Slippery Slope of Acceptance
Consider Nazi Germany. Under cultural relativism, we can't say the Holocaust was morally wrong — we can only say it was accepted by German culture at the time. Same with slavery in the American South. That's why same with any practice that a society endorses, no matter how horrific. The moral progress we celebrate — women's rights, civil rights, human rights — suddenly becomes impossible to justify. You can't say past generations were wrong if morality is just whatever your culture decides Small thing, real impact. Less friction, more output..
That's the challenge Rachels identified. Cultural relativism looks like tolerance, but it actually undermines the very possibility of moral criticism.
Why It Matters: The Stakes of Moral Thinking
Here's what most people miss about this debate: it's not just philosophy class material. The way we think about morality shapes everything. It affects how we treat strangers, how we respond to injustice, how we raise our children Easy to understand, harder to ignore..
When cultural relativism wins, we lose our ability to say that some things are just wrong. Worth adding: period. Think about what happens when we encounter practices like honor killings, child marriage, or systematic oppression. That's why if we can only say "that's their culture," we give up our moral agency. We become passive observers instead of agents of change But it adds up..
Rachels argued that this matters because human rights depend on the idea that there are universal moral standards. Practically speaking, that's not tolerance. In real terms, without them, we're left with might makes right — whoever has the bigger army or the more dominant culture gets to define morality. That's moral nihilism dressed up as open-mindedness Still holds up..
How Rachels Took Down Cultural Relativism
Rachels didn't just disagree with cultural relativism — he showed it was self-refuting. His argument was elegant in its simplicity.
The First Problem: It Can't Defend Itself
Here's the thing about cultural relativism: it claims that all moral truths are relative to culture. But that claim itself is supposed to be a universal truth. If cultural relativism is true universally, then it's not really cultural relativism — it's a universal moral principle. If it's only true relative to certain cultures, then it's not true for everyone. Either way, the theory collapses under its own weight.
Rachels made this point with devastating clarity. You can't consistently argue that there are no universal moral truths while simultaneously claiming that cultural relativism is a universal truth. It's a logical contradiction.
The Second Problem: It Denies Moral Progress
Think about how we view history. Consider this: we celebrate the abolition of slavery, the expansion of women's suffrage, the recognition of minority rights. But what would cultural relativism say about these changes?
If morality is just whatever your culture accepts, then the people who fought against slavery weren't morally superior — they were just different. The slaveholders weren't wrong; they just had a different cultural norm. But this makes moral progress impossible. You can't say that ending slavery was better than maintaining it if both were just culturally relative positions It's one of those things that adds up. Took long enough..
Rachels showed that this leads to absurd conclusions. Either we abandon the idea of moral progress, or we abandon cultural relativism That's the part that actually makes a difference..
The Third Problem: It Assumes What It Should Question
Here's what Rachels found particularly troubling: cultural relativism assumes that cultures are isolated, monolithic entities. But real cultures are messy, diverse, and constantly changing. Day to day, they borrow from each other, they argue internally, they evolve. The idea that you can neatly package a culture's morality and compare it to another culture's morality is itself a oversimplification Nothing fancy..
On top of that, cultural relativism often serves as a shield for oppression. When we say "that's just their culture," we sometimes excuse genuine harm. We stop asking whether people within those cultures actually want those practices, or whether they're being coerced.
Common Mistakes: What Most People Get Wrong
I know it sounds reasonable at first — respect other cultures, don't impose your values. But Rachels showed that this well-intentioned instinct often backfires. Here are the mistakes people make when they embrace cultural relativism without thinking it through.
Confusing Description with Prescription
Many people start with a reasonable observation: different cultures have different moral practices. This is descriptive — it's about what is. But cultural relativism jumps to a normative conclusion: therefore, no culture's practices are better or worse than another's. That leap doesn't follow.
Just because cultures disagree about morality doesn't mean there's no objective moral truth. It might just mean that some cultures are wrong. Scientists disagree about theories all the time — that doesn't mean there's no scientific truth Which is the point..
Treating Cultures as Monoliths
Real talk: cultures aren't unified blocks that speak with one voice. Practically speaking, within any culture, there are debates, disagreements, and dissenters. When we say "their culture believes X," we're often silencing the voices of people within that culture who disagree Which is the point..
Rachels pointed out that this is especially problematic when it comes to women's rights or minority rights. Who gets to speak for "the culture"? Usually, it's the most powerful voices — not the people most affected by oppressive practices.
Forgetting the Universal Human Element
Cultural relativism treats morality as a social construct, but it ignores something fundamental: we're all human. In real terms, we all have similar psychological needs and vulnerabilities. We all experience pain, fear, joy, and loss. The fact that different cultures express moral concerns differently doesn't mean there aren't universal moral foundations Easy to understand, harder to ignore..
Practical Tips: What Actually Works
So what's the alternative to cultural relativism? Rachels advocated for what he called "soft universalism" — the idea that while cultures express moral principles differently, there are core human values that transcend cultural boundaries.
Focus on Harm and Suffering
One practical approach is to focus on reducing harm and suffering, which seems to be a near-universal concern. And when we encounter practices in other cultures, we can ask: does this cause unnecessary suffering? Worth adding: does it respect people's autonomy and dignity? These aren't Western concepts — they're human concepts Worth knowing..
This doesn't mean imposing our solutions, but it does mean refusing to accept practices that cause gratuitous harm. It means listening to the voices of people within those cultures who are calling for change Worth knowing..
Embrace Moral Dialogue
Instead of saying "we can't judge," we should say "let's talk." Cross-cultural moral dialogue is more productive than either blind acceptance or arrogant dismissal. Plus, it requires humility — recognizing that our own culture has blind spots and has made moral mistakes. But it also requires courage — the willingness to say that some things are wrong, even when they're culturally accepted.
Distinguish Between Tradition and Justification
Just because something is traditional doesn't make it right. Just because something is widely accepted doesn
make it justified. Because of that, " Many cultural practices once considered untouchable — foot binding, slavery, denial of education to girls — were defended as tradition until people within and outside those cultures demanded better justifications. Here's the thing — " but "can this practice be defended by reasons that hold up to scrutiny? The crucial question isn't "is this traditional?They found none.
Easier said than done, but still worth knowing.
Support Internal Reformers
The most effective agents of moral change are almost always people working from within their own cultures. Our role isn't to swoop in as saviors but to amplify the voices of local activists, feminists, LGBTQ+ advocates, and human rights defenders who are already fighting for change. Consider this: they understand the cultural nuances we miss. They know which arguments resonate and which backfire. They take the risks. We can provide platforms, resources, and international pressure when they ask for it.
Accept That Progress Is Messy
Moral progress doesn't follow a straight line. This leads to we'll make mistakes — misreading contexts, applying double standards, confusing cultural difference with moral error. Here's the thing — a society might advance on gender equality while regressing on free speech. But individuals hold contradictory beliefs. But cultures evolve unevenly. The answer isn't to retreat into relativism but to stay engaged, stay humble, and keep correcting course.
Conclusion
Cultural relativism started as a methodological tool for anthropologists — a way to suspend judgment long enough to understand a culture on its own terms. It became a moral doctrine that paralyzes us when understanding isn't enough.
James Rachels showed us the exit. So naturally, we can acknowledge cultural diversity without surrendering moral judgment. Because of that, we can respect people's autonomy without respecting every practice that violates it. We can listen deeply without agreeing silently.
The alternative to cultural relativism isn't cultural imperialism. It's moral seriousness — the willingness to say "this causes harm" and "this respects dignity" across cultural lines, while remaining open to the possibility that we're the ones who need to learn. That's not arrogance. That's what it means to take morality seriously enough to argue about it, across every boundary we've drawn.
