Size is not always a gauge of significance. The issue that I propose to address here centers on a single clause from the Summa theologiae. But it goes nearly to the heart of St Thomas's teaching on natural law. It concerns the way in which Thomas thinks the human mind comes to understand good and evil. The specific question raised by the clause is the role played in this process by what Thomas calls "natural inclination." This question leads to an even more basic one: what it is, for Thomas, that constitutes a truly intellectual grasp of the good.

Does St Thomas Aquinas have anything to teach us on the subject of atheism? We might doubt it, even if we share his basic outlook. The reason would be the very fact that in his day there were so few who did not share it. It was, as they say, an age of faith. The profession of some sort of religious belief, indeed monotheism, was virtually universal, not just in Europe but in practically all of what Europeans then knew of the world. No doubt there were individual cases of "godlessness". The learned would also have known something about atheistic philosophies in pagan antiquity. But on the whole, the medievals seem to have had little incentive to take atheism very seriously. It hardly comes as a surprise to find that St Thomas's own writings contain no thematic treatment of it. Only in modernity does "serious" atheism seem to resurface.
