 A problem with this formulation is that some normative claims are analytic or conceptual truths. An example might be the claim that murder is wrong. A trivial example is the claim that wrongful killing is wrong. To address this issue we can take the error theorist to claim that all basic substantive normative claims are false. The idea here is that analytic and conceptual normative truths are not substantive. (But see Cuneo &amp; Shafer-Landau 2014.)
