Culture is custom. This idea holds that culture is structurally undifferentiated,
that what you see is what you get. … Culture here is virtually synonymous
with ‘tradition’, or customary ways of behaving. … Culture here
reduces to a sort of surface-level etiquette. Cultural variation is, as Peter
Black once put it, merely a matter of ‘differential etiquette’. Once again,
individual agency is downplayed.
