Prudential Parity Objections to the Moral Error Theory

Abstract

According to the moral error theory, all moral judgments are false. Until lately, most error theorists were local error theorists; they targeted moral judgments specifically and were less skeptical of other normative areas. These error theorists now face so-called “prudential parity objections”, according to which whatever evidence there is in favor of the moral error theory is also evidence for a prudential error theory. The present paper rejects three prudential parity objections: one based on the alleged irreducible normativity of prudential reasons; another on the lack of a story about the normativity of hypothetical reasons; yet another on the very nature of reasons generally. I argue that these objections leave an important variant of a local moral error theory intact.
