 A fully informative ascriptive supervenience thesis would explain how we should understand the mistake claimed by Ascriptive. There are several possibilities, of which four are worth emphasizing. The claimed mistake could be alethic, consisting in having made at least one judgment with a false content. Or it might be epistemic: consisting in making at least one epistemically unjustified judgment. It could be conceptual, consisting in judging in a way that is inconsistent with the meanings of ethical words. Finally, it might be characterized as ethical, consisting in making a judgment in a way that is vicious or ethically objectionable. (Note that the relevant judgment might be mistaken in more than one of these ways.)
