Imagine landing in a new country where a gesture you consider polite is taken as an insult. If manners can flip that fast, can morality do the same?
RELATIVISM: MORALITY BY LOCAL CUSTOM
Moral relativism says right and wrong depend on a culture, community, or historical moment—like traffic rules. Driving on the left isn’t “immoral” in Britain; it’s simply the local norm. Relativists notice that practices around marriage, punishment, gender roles, and truth-telling vary widely, and they argue that moral judgment makes sense only within a shared way of life.
Relativism can be a humility workout: it nudges you to ask, “Am I condemning this because it’s harmful—or because it’s unfamiliar?” It also explains why moral debates can feel like people using different dictionaries. But relativism comes with a nerve-testing question: if a culture approves of cruelty, does that make cruelty right there?
““Custom is the great guide of human life.””
— David Hume
OBJECTIVITY: MORALITY WITH A BACKBONE
Moral objectivism claims some moral truths hold regardless of what any society thinks—more like mathematics than manners. On this view, a practice can be widespread and still wrong, the way everyone once “knew” the sun circled the earth. Objectivists often point to human rights, the wrongness of torture, or the idea that like cases should be treated alike as candidates for universal moral standards.
Objectivity doesn’t require thinking every culture is identical; it requires believing there are better and worse answers to moral questions. Philosophers build objectivist arguments in different ways: consequences (utilitarianism), duties (Kant), virtue and human flourishing (Aristotle), or compassion and reducing suffering (echoing Buddhist ethics). The shared ambition is a moral map that still works when the local signage changes.
Relativism isn’t the same as tolerance. You can be a relativist and still approve of harsh punishment (because your culture does), and you can be an objectivist and still be culturally sensitive (because you distinguish “different” from “harmful”).
A PRACTICAL TEST: DISAGREEMENT VS. ERROR
Here’s a simple diagnostic: when two cultures clash, are they just expressing different preferences, or can one side be mistaken? If morality is like taste—“I like spicy food”—disagreement doesn’t imply error. If morality is like medicine—“This treatment helps”—then disagreement might mean someone is wrong about what harms or heals.
““If you are pained by any external thing, it is not this thing that disturbs you, but your own judgment about it.””
— Epictetus
- Explains moral diversity by rooting ethics in culture and context
- Encourages humility: ‘Maybe my norms aren’t universal’
- Struggles to criticize harmful practices without borrowing universal standards
- Allows cross-cultural moral criticism and the idea of moral progress
- Supports universal claims like human rights
- Must justify where universal standards come from (reason, nature, flourishing, etc.)
When you encounter a moral difference, ask two questions: (1) Who is harmed or helped, and how? (2) What reasons are offered, and do they generalize to similar cases? This keeps you curious without going morally blank.
- Relativism treats morality like local rules: meaningful within a culture, variable across cultures.
- Objectivism treats some moral claims as universally true, even if widely disputed.
- Relativism promotes humility but risks moral paralysis when facing injustice.
- Objectivism enables moral critique and ‘moral progress’ but must defend its foundations.
- A practical approach: separate unfamiliar customs from harmful practices using harm and reasons.
