Against Irreducibility-Parity

It is argued that the second version of the parity premise—irreducibility-parity—is false. It is false because epistemic judgements, unlike moral judgements, are committed to merely reducibly normative properties. The argument for this is based on the same basic rationale outlined in chapter 3: epistemic judgements are normative or evaluative only in the sense of normative or evaluative judgements within ‘institutions’ such as sports and games, etiquette, fashion, and the law. A ‘back-up’ view is introduced: even if irreducibility-parity is true, the analogy between epistemic judgements and normative or evaluative judgements within institutions can yet be used to render the epistemic error theory less implausible than it may at first appear.
