 These issues remain open in part because Aristotle seems most interested in establishing a conception of the formal structure of “particular” justice, which seems to reflect a conception of desert. He distinguishes between justice in distribution and justice in rectification. The former, he claims, adheres to a kind of proportionality, in which what each deserves is proportional to the relationship between the contributions. If A contributes twice as much as B (of whatever the metric of merit is relevant in some particular case), then A’s return ought also to be twice B’s. This conception of distributive justice obviously lends itself to “goods of fortune” — and to some goods, like wealth, more obviously than others — but it need not in principle be confined to such goods, although the examples Aristotle provides suggest such applications. Similarly, justice in rectification involves a sort of “arithmetical proportion.” If C defrauds D by amount X, then justice requires depriving C of X and restoring X to D, as a matter of reestablishing a kind of equality between them. These structural devices are elegant and attractive, but they leave open a number of questions (LeBar, forthcoming). First, as indicated, to what are we to suppose they apply? Second, in what way do they figure into the nature of the person who is just in the particular sense? (That is, how are they related to justice as a virtue?) Does a model of particular justice as a virtue fit the general model of virtue as a mean, and if so, what sort of mean is it? Aristotle seems torn between a conception of justice as a virtue in his distinctive understanding of what a virtue is — with a requirement that one have all the virtues to have any (Nicomachean EthicsVI.13), and rooted in the doctrine of the mean — and justice as having the form of a formal normative structure, to which the virtue threatens to become subsidiary. All this is to leave aside questions of the relation between this “particular” sense of justice and political justice, and the role of the virtue of justice in the individual as it contributes to justice in the polis.
