Some cognitivists argue that some expressions like "courageous" have both a factual as well as a normative component which cannot be distinguished by analysis. Prescriptivists argue that according to context, either the factual or the normative component of the meaning is dominant. The sentence "Hero A behaved courageously" is wrong, if A ran away in the face of danger. But the sentence "Be brave and fight for the glory of your country!" has no truth value and cannot be falsified by someone who does not join the army.
