 In fact, this point — that “public utility is the sole origin of justice” — is the point of Hume’s discussion of justice in the Enquiries (III.I, ¶145). Scarcity imposes a need for us to distinguish mine from thine, and we have not sufficient generosity in our natures to do without property rules (as we might, say, in our families). And once again Hume argues that our recognition of the utility and necessity of justice provides “entire command over our sentiments” (E III.II, ¶163).As David Johnston observes (Johnston 2011, p. 138), Hume’s understanding of the value of justice as instrumental in the promotion of utility marks a sharp shift from earlier understandings which invoked various forms of reciprocity in understanding that value.
