Ethical relativism is the theory that holds that morality is relative to the norms of one's culture. That is, whether an action is right or wrong depends on the moral norms of the society in which it is practiced. The same action may be morally right in one society but be morally wrong in another. The only moral standards against which a society's practices can be judged are its own. If ethical relativism is correct, there can be no common framework for resolving moral disputes or for reaching agreement on ethical matters among members of different societies.
Most ethicists reject the theory of ethical relativism.
