How to explain the possibility of wholesale moral error: a reply to Akhlaghi COMMENT

Farbod Akhlaghi has argued that noncognitivists and naturalists cannot explain the epistemic possibility of wholesale moral error. He thinks this shows that noncognitivism and naturalism are false. I argue that noncognitivists and naturalists have no trouble explaining the epistemic possibility of wholesale moral error and that the requirement to explain this possibility is plausible only on one particular conception of epistemic possibility.
