The Eternal Law in Augustine's Early Investigation of Justice

Abstract

In my dissertation I seek to contribute to the revival of interest in Augustine’s political thought by attempting to uncover his doctrine of eternal law. While absent from his mature writings, including the City of God, this doctrine is central to the investigation of justice in Augustine’s early writings. After considering Augustine’s summary of this early investigation in the Confessions, the most surprising feature of which is Augustine’s insistence on the importance of specifically political questions to his mature understanding of justice, I take up the two treatments of eternal law. In the dialogue On Free Choice, the eternal law is contrasted with the temporal law and is understood in terms of the fundamental command to “order,” which means in the first place wisdom, but also “right and honorable” action. In the anti-Manichean polemic Contra Faustum, the eternal law is presented as the will of God that commands the preservation of the natural order, which means that actions are truly just insofar as they conduce to “mortal health.” I argue that these two discussions of eternal law indicate the limitations of any kind of “higher law” doctrine. On Free Choice demonstrates the difficulty of breaking free of the guidance of temporal law and its harmonization of the demands of eternal and temporal law depends on an understanding of moral virtue whose independence is rather assumed than proven. Contra Faustum shows that the natural ends of self-preservation, procreation, and civic peace are only the beginning points of moral reasoning, since the pursuit of those ends is governed by further moral criteria that cannot easily be understood in terms of nature. In the end, then, I argue that the doctrine of eternal law, while illuminating a great deal about the problems of politics and morality as Augustine encountered them, points to the crucial importance of the question of human virtue and of acquiring the prudence that provides for this virtue in light of the necessary limitations of political life. It is probably for this reason that Augustine does not return to the doctrine in his later writings and does not rely on it in his reconciliation of the two cities in the City of God.
