 What counts as definitional of morality, in either sense of “morality”, is controversial. Moreover, the line between what is part of a definition, in the sense at issue, and what is part of a moral theory, is not entirely sharp. For example, some might regard it as definitional of morality, in the normative sense, that it governs only interpersonal interactions. Others, however, might take this to be a substantive theoretical claim. Some might take it as definitional of “morality” in its descriptive sense that it be a code of conduct that a person or group takes to be most important. But others might say that attention to religion casts doubt on this idea.
