 In fact, Reid believes that reflection on our concepts of primary justice reveals more than this. It also reveals that these concepts are irreducible to other normative concepts and fundamental to moral thinking. Reid’s way of making this point is to note that Hume attempts to ground the rules of justice not just in our notion of our good on the whole, but also in considerations of utility. Reid holds that this is a mistake. To “have the conception of justice,” it is necessary that “one perceive its obligation distinct from its utility” (EAP V.v: 306). Considerations of utility, Reid holds, are the wrong sort of reasons to ground accountability relations, which are among the objects of our concepts of primary justice. In his book, The Second-Person Standpoint, Stephen Darwall puts the point like this: To see that something is required of another is to take up the “second-person standpoint” with regard to him. To occupy this standpoint is to have the authority to hold that person accountable for not doing what is required of him. Failure to perform an act that increases utility, however, is not the right sort of thing for which to hold someone accountable (see Darwall 2006, especially the discussion of Reid in Ch. 8; see also Wolterstorff 2010).
