as anthropology and sociology, which simply admit that it is incorrect to assume that the same moral or ethical frameworks are always in play in all historical and cultural circumstances. Meta-ethical Meta-ethical moral relativists believe not only that people disagree about moral issues, but that terms such as "good", "bad", "right" and "wrong" do not stand subject to universal truth conditions at all; rather, they are relative to the traditions, convictions, or practices of an individual or a group of people. The American anthropologist William Graham Sumner was an influential advocate of this view. He argues in his 1906 work Folkways that what people consider right and wrong is shaped entirely—not primarily—by the traditions, customs, and practices of their culture. Moreover, since in his analysis of human understanding there cannot be any higher moral standard than that provided by the local morals of a culture, no trans-cultural judgement about the rightness or wrongness of a culture's morals could possibly be justified. Meta-ethical relativists are, first, descriptive relativists: they believe that, given the same set of facts, some societies or individuals will have a fundamental disagreement about what a person ought to do or prefer (based on societal or individual norms). What's more, they argue that one cannot adjudicate these disagreements using any available independent standard of evaluation—any appeal to a relevant standard would always be merely personal or at best societal. This view contrasts with moral universalism, which argues that, even though well-intentioned persons disagree, and some may even remain unpersuadable (e.g. someone who is closed-minded), there is still a meaningful sense in which an action could be more "moral" (morally preferable) than another; that is, they believe there are objective standards of evaluation that seem worth calling "moral facts"—regardless of whether they are universally accepted. Normative Normative moral relativists believe not only the meta-ethical thesis, but that it has normative implications on what we ought to do. Normative moral relativists argue that meta-ethical relativism implies that we ought to tolerate the behavior of others even when it runs counter to our personal or cultural moral standards. Most philosophers do not agree, partially because of the challenges of arriving at an "ought" from relativistic premises. Meta-ethical relativism seems to eliminate the normative relativist's ability to make prescriptive claims. In other words, normative relativism may find it difficult to make a statement like "we think it is moral to tolerate behaviour"
