 Some psychologists, such as Haidt, take morality to include concern with, at least, all three of the triad of (1) harm, (2) purity, and (3) loyalty, and hold that different members of a society can and do take different features of morality to be most important. But beyond a concern with avoiding and preventing such harms to members of certain groups, there may be no common content shared by all moralities in the descriptive sense. Nor may there be any common justification that those who accept morality claim for it; some may appeal to religion, others to tradition, and others to rational human nature. Beyond the concern with harm, the only other feature that all descriptive moralities have in common is that they are put forward by an individual or a group, usually a society, in which case they provide a guide for the behavior of the people in that group or society. In the descriptive sense of “morality”, morality may not even incorporate impartiality with regard to all moral agents, and it may not be universalizable in any significant way (compare MacIntyre 1957).
