 Aquinas arranged the Summa Theologiae’s exposition of morality within a classification, not of the goods to which rational acts are directed, nor of types of act, nor of practical reason’s standards, but of the virtues. Explicable as a reflective theological project of depicting the flourishing or deviations of human beings in an account of the whole movement of creature from their origin to their fulfillment, his decision to adopt this superstructure has tended to obscure the real foundations of his ethics. As one would expect from the considerations sketched in the preceding paragraph, his actual arguments about what is right and wrong, virtuous or vicious, get their premises not from analysis of the virtues at stake but rather from the principles and more specific standards, norms, precepts or rules of practical reason(ableness). It is the conclusions of these arguments that are then re-expressed in terms of what is contrary to or in line with one or more of the virtues.
