My most recent book, published by Cambridge University Press, is two full-length books in one: A printed book, Commentary on Thomas Aquinas's Treatise on Law (which you can buy from Amazon or buy from Cambridge), and a free online supplement called the Companion to the Commentary (which you can download from my website or download from Cambridge).
The Commentary is a classical, line-by-line exploration of Questions 90-97. The Companion includes additional line-by-line commentary on selections from Questions 98-108, as well as thematic discussions of various fundamental issues in the Treatise on Law, keyed to the Articles in which they appear. Why not combine the Commentary and Companion into a single book? Because that would have made it 800 pages, and my editor thinks a book shouldn’t be like a concrete block.
A superb line-by-line commentary . . . the first complete commentary of this sort in centuries. Offers insightful comments on the implications of modern philosophical developments for interpreting and evaluating the positions taken by Aquinas. An enormously valuable text, not only for scholars specializing in the field but also for those just embarking on a careful study of the work. – Fr. Joseph W. Koterski, S.J., Associate Professor of Philosophy, Fordham University
An indispensable tool for student, teacher, and scholar. Providing an overall context for each question, then pairing his own paraphrase with the translation of the Dominican Fathers, Budziszewski proceeds to comment in detail on each objection, sed contra, answer, and reply to objection. The important yet difficult Treatise on Law is laid open to our full view by Professor Budziszewski. – John Hittinger, Professor of Philosophy, Center for Thomistic Studies, University of St. Thomas
No area of public life is more confused than law and what it is. In this context, few books could be more significant than a complete, accurate, and thorough reading and rereading of Aquinas’s famous Treatise on Law. Budziszewski has performed an enormous service to intelligence and to clarity of public order in providing this detailed, yet readable and intellectually profound, commentary. – James V. Schall, S.J., Professor Emeritus, Georgetown University
