 Summing up: Some moral anti-realists will count as moral skeptics, but some may believe in moral knowledge. Some moral anti-realists will be relativists, but some may be moral absolutists (and many are neither). Some moral anti-realists will be moral naturalists, but some may be moral non-naturalists, and some will be neither moral naturalists nor non-naturalists. These various positions can be combined into a potentially bewildering array of possible complex metaethical positions (e.g., non-skeptical, relativistic, non-naturalistic moral anti-realism)—though, needless to say, these views may vary greatly in plausibility.
