 It is not clear, however, that the demands of impartial benevolence are sufficient to exhaust those of morality. Treating a person appropriately and respectfully may well require certain sorts of emotional and/or cognitive responses: sensitivity to her needs and values, empathy for her suffering, and the like. But if these responses are pictured as the results of positive traits or attributes (and not simply as, say, the result of a lack of bias or prejudice), then it is not clear that merely being impartial between persons is sufficient to guarantee that one will possess and display the necessary sensitivities. Indeed, characterizations of impartial agents which proceed in negative terms (that is, by defining various preferences, emotions or bits of information that she does not possess or that do not move her) often risk picturing the impartial agent as impersonal and even indifferent (Henberg 1978; Brandt 1954).
