Impossible Ethics: Do Population Ethical Impossibility Results Support Moral Skepticism and/or Anti‐Realism?

In this paper, I discuss two different metaethical challenges based on population ethical impossibility results. According to the anti‐realist challenge, the results pose a serious threat to the existence of objective moral facts. According to the skeptical challenge, the results pose a serious threat to the reliability of our moral intuitions. My aim is to systematically explore and evaluate these challenges. In addition to clarifying the issues, I argue that population ethical impossibility results do not in fact support any anti‐realist or skeptical conclusions.
