 Even more controversial was the question of whether more substantive social requirements should be built into the definition of morality. For example, Toulmin (1950) argued that a concern for the harmony of society is part of the meaning of “moral”, and Baier (1958 [1970: 199ff]) proposed that moral rules “must be for the good of everyone alike”. On these substantive principles, too, it is clear that no agreement was reached.
