Abstract

Recent decades have seen a shift away from the traditional view that Aquinas's theory of the natural law is meant to supply us with normative guidance grounded in a substantive theory of human nature. In the present essay, I argue that this is a mistake. Expanding on the suggestions of Jean Porter and Ralph McInerny, I defend a derivationist reading of ST I-II, Q. 94, A. 2 according to which Aquinas takes our knowledge of the genuine goods of human life and their proper ordering to one another to be self-evident only to the wise who are able to discern the truth about our God-given human nature. I then show that this reading provides a better account of Aquinas's view than two recent alternatives: John Finnis's brand of inclinationism and Daniel Mark Nelson's virtue-based interpretation
