Christian Ethics - Scholasticism

Scholasticism

A sharper line of separation between philosophy and theology, and in particular between ethics and moral theology, is first met with in the works of the great Schoolmen of the Middle Ages, especially of Albertus Magnus (1193–1280), Thomas Aquinas (1225–1274), Bonaventure (1221–1274), and Duns Scotus (1274–1308). Philosophy and, by means of it, theology reaped abundant fruit from the works of Aristotle, which had until then been a sealed treasure to Western civilization, and had first been elucidated by the detailed and profound commentaries of Albert the Great and Thomas Aquinas and pressed into the service of Christian philosophy.

The same is particularly true as regards ethics. Thomas, in his commentaries on the political and ethical writings of Aristotle, in his Summa contra Gentiles and his Quaestiones disputatae, treated with his wonted clearness and penetration nearly the whole range of ethics in a purely philosophical manner, so that even to the present day his words are an inexhaustible source from which ethics draws its supply. On the foundations laid by him the Catholic philosophers and theologians of succeeding ages have continued to build. In his Summa Theologiae, Thomas locates ethics within the context of theology. For example, he discusses the ethics of buying and selling and concludes that although it may be legal (according to human law) to sell an object for more that it is worth, Divine law "leaves nothing unpunished that is contrary to virtue." The question of beatiudo, perfect happiness in the possession of God, is posited as the goal of human life. Thomas also argues that the human being by reflection on human nature's inclinations discovers a law, that is the natural law, which is "man's participation in the divine law."

In the fourteenth and fifteenth centuries, thanks especially to the influence of the so-called Nominalists, a period of stagnation and decline set in, but the sixteenth century is marked by a revival. Ethical questions, also, though largely treated in connection with theology, are again made the subject of careful investigation. Examples include the theologians Francisco de Vitoria, Dominicus Soto, Luis de Molina, Francisco Suarez, Leonardus Lessius, Juan de Lugo, Juan Caramuel y Lobkowitz, and Alphonsus Liguori. Among topics they discussed was the ethics of action in case of doubt, leading to the doctrine of probabilism. Since the sixteenth century, special chairs of ethics (moral philosophy) have been erected in many Catholic universities. The larger, purely philosophical works on ethics, however, do not appear until the seventeenth and eighteenth centuries, as an example of which we may instance the production of Ign. Schwarz, "Instituitiones juris universalis naturae et gentium" (1743).
