 Aquinas’ well-known discussion of law in ST I-II qq. 90–97 (a discussion which actually extends through the less studied qq. 98–105) has been justly admired by jurists and other thinkers not otherwise much interested in his work. But it is shaped by his concern there (i) to present for beginner students of theology an overview of the universe and of the vast sweep of creatures out from their divine creator and back to the same transcendent being as their ultimate destiny, and (ii) to synthesize the traditional vocabulary and classic theological sources on law. So prominence is there given to the “eternal law” by which God governs even inanimate creatures (as by the laws of physics, etc.), and to the “participation” of natural moral law in that eternal law. But when he is free from these textbookish constraints he emphasizes that law’s most essential feature is something which is not true of the laws of nature (physics, biology, etc.), namely that it is an appeal to the mind, choice, moral strength (virtus) and love of those subject to the law: ScG III cc. 114–117; this is quietly indicated also in ST I-II q. 91 a. 2 ad 3.
