  Thus far we have been considering internalism as a reason to accept non-cognitivism based on a sort of inference to the best explanation. Insofar as non-cognitivism can explain the connection between normative or moral judgments and motivation we have some reason to accept it. But the explanations so far have relied on the positive part of non-cognitivism – the part that connects the meanings of moral terms to commendation or the expression of attitudes. The denial of cognitivism so far has played no role. Since the expressivist or prescriptivist component of non-cognitivist theories does not by itself entail the denial of cognitivism, a cognitivist could take them on board and explain a species of internalism just as non-cognitivists do (Copp 2001).
