 A more radical critique of the paradigmatic natural law account of the connection between the good and the right calls into question the very idea that one can get principles of moral rightness merely from what constitutes a defective response to the good. According to this critique, while it is true that one might be able to come up with some notion of unreasonableness by appeal to the notion of what is defective response to the human goods, the notion of moral rightness belongs to a family of concepts distinct from that to which the notion of reasonableness belongs. On this view, moral rightness belongs to the obligation family, and the concept of obligation is irreducibly social: one is under an obligation only if one is subject to some sort of demand in the context of a social relationship (see, for an example of this view from a theological voluntarist perspective, Adams 1999, pp. 238–241; see, for an example of this view with a Kantian twist, Darwall 2006). It is part of the logic of obligation that when one is under an obligation, that condition has resulted from a demand imposed on him or her by some other party. So, according to this line of criticism, the paradigmatic natural law view is unable to show that the natural law is intrinsically morally authoritative: the precepts of the natural law can be rules that all of us human beings are obligated to obey, that it would be wrong for us to disobey, and that we would be guilty for flouting only if these precepts are imposed upon us by an authoritative being — perhaps a being like God.
