‘Natural Inclinations’ in Aquinas and his Modern Interpreters

In this paper, I tackle Aquinas’s notion of ‘natural inclinations’, specifically as it occurs in his seminal elaboration of the natural law in Summa Theologiae I-II. Question 94. Article 2. Maintaining that it constitutes a departure from Aristotle’s terminology, and is hence puzzling, I go on to investigate a raft of modern, mainly Anglophone, interpretations of the concept. Beginning with Jacques Maritain, I move through the broadly chronological sequence of John Finnis, Jean Porter, Steven Jensen, Justin Matchulat and Stephen Brock. In each case, I argue that – despite these scholars’ philosophical ingenuity and textual facility – there are crucial problems with their respective approaches and construals. I end the paper by outlining my own construal of ‘natural inclinations’, which, even if not bolstered by heavy textual scholarship, is at least coherent and, moreover, avoids the philosophical pitfalls of the above interpretations.
