As Feser and Bessete wind up their argument about punishment as such, they note that punishment has traditionally been considered to have several purposes: in addition to retribution, it can also serve to deter future crime or rehabilitate the criminal. “But,” they go on, “as our discussion indicates, for the natural law theorist, retribution is not only a legitimate end of punishment: it is the fundamental end” (page 40). Further down they make explicit what they mean: “For, all things being equal, we may punish even if we will thereby achieve no end other than retribution; but we may not punish if retribution is not at least one of the ends aimed at.”
However, still further in, F&B allow that “some traditional natural law theorists think” that we can’t “inflict a punishment merely to secure retributive justice,” and they go on to offer some citations from Aquinas (57). It was only on my second read that I realized F&B are saying that Aquinas disagrees with them about punishment. Perhaps one reason it was not clear to me at first is that they do not cite Aquinas’s clearest statement on the point: “Vengeance is lawful and virtuous so far as it tends to the prevention of evil” (ST II-II 108.2).
