 Even if Sinnott-Armstrong’s position is correct with regard to morality in the descriptive sense, there might nevertheless be a code of conduct that, given certain specified conditions, would be put forward by all rational agents. That is, even if the descriptive sense of morality is a family-resemblance notion, vaguely bordered and open-textured, or even if it is significantly disjunctive and disunified, the normative sense might not be. By way of comparison, we might think of the notion of food in two ways: as what people regard as food, and as what they would regard as food if they were rational and fully informed. Certainly there is not much that unifies the first category: not even being digestible or nutritious, since people regard various indigestible and non-nutritious substances as food, and forego much that is digestible and nutritious. But that does not mean that we cannot theorize about what it would be rational to regard as food.
