First, Ayesha has offered a definition of cultural relativism. It goes something like this:

• Values vary from culture to culture.
• People acquire their values from the culture in which they are raised.
• The values of a culture are binding on the people living in that culture, but not beyond it.
• There is no way to prove the superiority of one culture's values.
• We should be tolerant of the values of other cultures and not interfere with those living according to those values.

Second, John has offered a negative definition of ethical relativism. The old via negativa. You philosophers may recall that from Aquinas. Very good indeed. Ethical relativism denies the following:

• Moral evaluations are objective in some sense. By objective, we mean that they have a source apart from human decisions, choices, attitudes, and feelings.
• There is only one moral truth. If two moral evaluations conflict, one of them is incorrect.
• The same morality is binding on all people (or, as some would say, on all reasonable beings).
