 Some, including Hare (1952, 1963), have been tempted to argue against the possibility of a substantive definition of morality, on the basis of the claim that moral disapproval is an attitude that can be directed at anything whatsoever. Foot (1958a, 1958b), argued against this idea, but the substantive definition still has the drawback is that it does not, somehow, seem to get at the essence of morality. One might suggest that the substantive definition has the advantage of including Divine Command theories of morality, while such theories might seem to make trouble for definitions based on the plausible schema given above. But it is plausible to hold that Divine Command theories rest on Natural Law theories, which do in fact fit the schema. Divine Command theories that do not rest on Natural Law might make trouble for the schema, but one might also think that such theories rest instead on a confusion, since they seem to entail that God might have made it immoral to act beneficently.
