James V. Schall, The Intellectual Context of Natural Law, 38 Am. J. Juris. 85 (1993).
From the author's introduction:
The subject of natural law, though one of the really fascinating subjects of our philosophic and legal tradition, is not widely considered today even in law schools or political science departments, let alone in philosophic or theological treatises, all of which actually have something to say about the subject. However, it is a perennial theme of remarkable vigor and interest to those perceptive thinkers who are brave enough to reconsider the topic.
