 Consider favors. Favors, says Reid, are naturally connected with the benevolent affection of gratitude; they are what merit this response. But to express gratitude toward someone who has performed a favor is to believe or presuppose that that agent has benefited you by going beyond what is owed. Or consider being injured (as opposed to simply being harmed). Being injured, says Reid, is naturally connected with the malevolent affection of resentment. To express resentment toward an agent who has injured you is, however, to believe or presuppose that he has wronged you, given you less than you deserve. If this is right, we do not derive the primary concepts of justice from an interest to secure our good on the whole. To the contrary, the reverse is true; we can arrive at a notion of our own good on the whole only if we possess the concepts of primary justice. But if so, we cannot hold that we somehow constructed our notions and the rules of justice from a concern to secure our good on the whole. Our notion of our good on the whole presupposes them (see Cuneo 2015 and Powell and Yaffe 2015).
