Michael Zuckert. "The Fullness of Being: Thomas Aquinas and the Modern Critique of Natural Law." The Review of Politics 69, no. 1 (2007): 28-47.

Abstract:

Interest in natural law theory regularly revives but the question of whether Aquinas’ classic version is viable depends on whether his doctrine has the resources to respond to the classic early modern critiques that were made of it. It is argued that he does have the resources to so respond, although the response pushes the ultimate philosophic question back to the issue of the validity of his natural theology.
