 Nietzsche’s primary argument for anti-realism about value is explanatory: moral facts don’t figure in the “best explanation” of experience, and so are not real constituents of the objective world (Leiter 2019: 17–48). Moral values, in short, can be “explained away.” Such a conclusion follows from Nietzsche’s naturalism (on the latter, see the competing accounts in Janaway 2007 and Leiter 2013). As we saw in the context of Nietzsche’s critique of morality, Nietzsche thinks a person’s moral beliefs can be explained in naturalistic terms, i.e., in terms of type-facts about that person. Thus, to explain a person’s moral judgments, one needn’t appeal to the existence of objective moral facts: psycho-physical facts about the person suffice. Thus, since non-evaluative type-facts are the primary explanatory facts, and since explanatory power is the mark of objective facts, it appears that there cannot be any value facts. Moral judgments and evaluations are “images” and “fantasies,” says Nietzsche, the mere effects of type-facts about agents (D 119).
