 The second fact that will play an important role in our discussion of social domain theory concerns the outcome of the philosophers’ attempts to find a definition of morality. After decades of effort by dozens of authors, including some of the most eminent philosophers writing in the second half of the twentieth century, the project failed to reach anything close to consensus. Disagreements persisted on just about every issue of methodology and substance. One central methodological issue was whether the goal of the endeavor was descriptive, aimed at characterizing how the concept of morality is actually used, or normative, aimed at specifying how the concept of morality should be used. Frankena took the project to be normative, and he claimed a number of prominent philosophers, including Richard Brandt and G.H. von Wright, as allies. But other eminent figures, including R.M. Hare, H.L.A. Hart, and Alan Gewirth, took the project to be descriptive (Frankena 1967 [1970: 149–151]).
