 The most difficult case to resolve according to the overall argument of the book is that of advantage when understood as political ambition, driven by greatness of spirit. As Cicero acknowledges, and as was especially true in the highest echelons of Roman society, “Men are led most of all to being overwhelmed by forgetfulness of justice when they slip into desiring positions of command or honour or glory” (I.26). The solution is to aim only at true glory, such as can be gained only through the fulfillment of one’s officia. Similar casuistry enables Cicero to resolve in accordance with his thesis a range of common cases where advantage might be sought at the expense of justice (in administering the estate of an orphan, for example, a common duty of eminent Romans). Yet such casuistry is always advanced within a context of celebration of justice and natural law: it is not simply that in fact justice never conflicts with advantage, but that justice properly understood is always to one’s advantage as a human being.
