'In this much-needed contribution to the lively debates that currently rage about natural law theory, Budziszewski provides a superb line-by-line commentary on the complete text of Aquinas' Treatise on Law - the first complete commentary of this sort in centuries. The Commentary 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., Fordham University, New York
