Take the idea that tyranny among leaders leads to revolt among followers. Confucius said something like this, using Chinese words appropriate to the Chinese Spring and Autumn period. Locke said it, too, using English words appropriate to his time. And Foucault said it, in modern French. The truth of the statement rests on human nature, which hasn't changed that much since the time of Confucius. The words, however, have changed a lot, as have the cultures. So you say what is more universally true using the word-meanings that are current for your culture. But just because the word-meanings are only valid within your culture, that doesn't mean that you can't make statements whose truth transcends your culture.
