 When “morality” is used in its normative sense, it need not have either of the two formal features that are essential to moralities referred to by the descriptive sense: that it be a code of conduct that is put forward by a society, group, or individual, or that it be accepted as a guide to behavior by the members of that society or group, or by that individual. Indeed, it is possible that morality, in the normative sense, has never been put forward by any particular society, by any group at all, or even by any individual. This is partly a consequence of the fact that “morality” in the normative sense is understood in terms of a conditional that is likely to be counterfactual: it is the code that would be endorsed by any fully rational person under certain conditions.
