  Different cultures may have different, conflicting customs, some of which may be morally wrong by our lights. Since other cultures’ customs may be wrong, by parity of reasoning, so might our own. The mere fact that a practice is traditional or customary, as the li (rituals, ceremonies) are, does not show that it is right in the objective, universal sense expressed by moral concepts such as ren (benevolence) and yi (righteousness, morality). The li thus cannot serve as an authoritative standard of a unified morality. We need to find other, objectively justified standards.
