Relativism

From EvaluationWiki

The doctrine that evaluative claims, always including ethical claims, and often also all knowledge and truth claims, are merely normative, i.e., merely amount to assertions that something is or is not of value according to local standards. The position immediately runs into trouble for two reasons. First, if taken to include all knowledge claims, it is self-referent (since it's a knowledge claim itself) and hence self-refuting, i.e., it's no more than a local opinion with no universal validity, but that's just what it claims to have. Second, there are many evaluative claims that appear to be true by definition and hence cannot be a mere matter of local custom (e.g., "Murder is wrong," "Health programs are better to the extent that they help more people to live longer and/or increase their quality of life.")
