 Despite the fact that theorists such as Sidgwick, Gert, Foot, and Goldman do not hold that moral behavior is rationally required, they are by no means precluded from using “morality” in the normative sense. Using “morality” in the normative sense, and holding that there is such a thing, only entails holding that rational people would put a certain system forward; it does not entail holding that rational people would always be motivated to follow that system themselves. But to the degree that a theorist would deny even the claim about endorsement, and hold instead that rational people might not only fail to act morally, but might even reject it as a public system, that theorist is either not using “morality” in a normative sense, or is denying the existence of morality in that sense. Such a theorist may also be using “morality” in a descriptive sense, or may not have any particular sense in mind.
