Are Morals Just Local?

In one line Customs differ widely, but that does not show that no custom is better or worse than another.

Travelers find that customs differ: how to greet, whom to honor, what counts as polite. Some conclude that morality is only local custom, with nothing to choose between one set and another. This is moral relativism.

The argument has a gap. That people disagree does not show that there is no better answer, any more than disagreement about the shape of the Earth once showed there was none. Many differences shrink when you look at the reasons: two cultures may value the same thing, such as respect, and express it differently.

Relativism also has an awkward result. If every culture is right by its own lights, no culture can be criticized for cruelty, and reformers inside a culture are always wrong. A careful view keeps humility about customs while still asking what harms and what helps.

The dinner abroad

Illustration: The dinner abroad

At a dinner abroad, Kai is told that it is rude to finish everything on the plate. Back home it is rude to leave any. He wonders which is right.

He asks his host, who says that a clean plate suggests the host did not give enough. Both customs show care for the host. Kai decides that the difference is in the code, not in the value, and saves his moral questions for practices that hurt people.

Try this today Pick a custom you dislike and ask what reasons its holders give, before you judge it.

Question 1 of 2

Kai learns that it is rude to finish a plate in one country and rude to leave food in another. He asks why.

What does his host’s answer show?

Question 2 of 2

A traveler says, “People disagree about morals, so there is no better or worse answer.”

Where is the gap in this argument?
