 For Aquinas, there are two key features of the natural law, features the acknowledgment of which structures his discussion of the natural law at Question 94 of the Prima Secundae of the Summa Theologiae. The first is that, when we focus on God’s role as the giver of the natural law, the natural law is just one aspect of divine providence; and so the theory of natural law is from that perspective just one part among others of the theory of divine providence. The second is that, when we focus on the human’s role as recipient of the natural law, the natural law constitutes the principles of practical rationality, those principles by which human action is to be judged as reasonable or unreasonable; and so the theory of natural law is from that perspective the preeminent part of the theory of practical rationality.
