One of the Aristotle's claims in the ergon argument was that every hexis which caused men's behaviour to be rational was an excellence. Aristotle says that feelings are embodied forms, and a proper definition of a feeling would be, for instance, a certain change of such and such a body, as a result of such and such a cause and for the sake of such and such an end. According to Socrates the moral virtue, is like arithmetical skill, which is a kind of knowledge brought about by the kind of enforced intimacy with its objects that a proper education provides. Cognitivists in general will be inclined to compare moral virtue more closely with knowledge than with taste, and they will rightly not be convinced by the argument which purports to show that the moral virtues must be tastes just because they are developed through training in pleasure and pain.
