 Explicit attempts, by philosophers, to define morality are hard to find, at least since the beginning of the twentieth century. One possible explanation for this is the combined effect of early positivistic worries about the metaphysical status of normative properties, followed (or augmented) by Wittgensteinian worries about definitions of any significant terms whatsoever. Whatever the explanation, when definitions have been offered, they have tended to be directed at the notion of moral judgment (Hare 1952, 1981) rather than at morality itself. However, to the degree that these definitions of moral judgment are adequate, they might, without much effort, be converted into definitions of morality in the descriptive sense. For example, a particular person’s morality might be regarded as the content of the basic moral judgments that person is prepared to accept.
