 One problem faced by realist normative conceptualism is that it arguably is a necessary truth that the properties referred to or represented by normative concepts are normative. For instance, arguably, if any property is referred to or represented by our concept &lt;wrong&gt; it is the property wrongness. And unless it embraces error theory, normative conceptualism agrees that there is a property that is referred to or represented by our concept &lt;wrong&gt;. So it is committed to there being a property wrongness. And it would seem to be a necessary truth that any such property is normative in itself and not merely in virtue of the fact that some normative concept of ours refers to it or represents it. If this is right, then unless it embraces error theory, realist normative conceptualism faces a fatal problem.
