Abstract

The fusion of law and virtue is a distinctive feature of the ethical writings of St. Thomas Aquinas, particularly of his most mature and most detailed ethical treatise, the secunda pars of the Summa Theologiae. By way of preface to his treatises on virtue and on law in the Summa, Thomas states that the former is an intrinsic, the latter an extrinsic, principle by which man is led to his end. It is evident from even these brief remarks that virtue and law are integral parts of an overarching moral pedagogy intended to lead man to his ultimate end. The end consists, as Thomas says, in the contemplation of the divine essence, but the possession of the intellectual and moral virtues is a prerequisite to the experience of the beatific vision. Hence, moral instruction, of which the secunda pars is an exemplary instance, is directed to the inculcation of the virtues--to the formation of character. ;In this context, the role of natural law is to circumscribe the parameters of the moral life and to provide a background to moral deliberation. Submission to human, divine, and finally eternal law marks the various stages in man's education in moral perfection. The hierarchy of the laws is thus parallel to the hierarchy of the virtues, natural and infused. Law, as the Thomistic dictum runs, is for the sake of virtue. Thomas' view of law, then, is teleological, not deontological; that is, laws are intelligible in light of an overarching conception of the goods of a community or of human nature. But the goods or practices which the laws are intended to succour are themselves embodiments of virtues such as justice. ;While a comprehensive treatment of the secunda pars is beyond the scope of this investigation, we will provide an analysis of exemplary instances of moral pedagogy in the Summa. From this examination of representative passages, it will be possible to defend certain conclusions concerning the doctrinal structure and rhetorical intent of the Summa
