  We might define a “natural fact” not in metaphysical terms, but rather in linguistic terms: as the kind of fact about which we make certain kinds of claims—natural or descriptive claims. Claims are or are not “natural” depending on what kind of terminology they use. Claims that use normative terminology like ‘good’, ‘bad’, ‘right’, ‘wrong’, etc. are normative claims. Claims that avoid this use of evaluative terminology, and instead use terminology common to the natural sciences, are natural claims. If moral claims and natural claims are synonymous, as the Analytic Naturalist holds, then moral and natural claims must refer to the same facts. If the moral claims refer to the same facts that natural claims refer to, it follows that moral claims refer to natural facts. Thus, Analytic Naturalism can provide us with a sensible and tractable explanation of how moral facts could be “natural” facts (Parfit 2011, chapters 24–25).
