To understand why the author critiques Maritain so sharply, it helps to contrast his modern, rights-focused framework with St. Thomas Aquinas’s original view of natural law , which is rooted in objective order and human nature. Here is a direct comparison of how their views differ across core philosophical dimensions: Dimension St. Thomas Aquinas (Classical Natural Law) Jacques Maritain (Modern Personalist Framework) Primary Focus Objective Right ( Ius ) & Obligations . The focus is on what is objectively fair in a relationship and what a person owes to God, neighbors, and the community. Subjective Natural Rights . The focus shifts to what the individual is entitled to possess or claim against others and the state. Source of Rights The Rational Cosmic Order .

Rights stem from the unique, transcendent value of the human person, heavily in...
Ultimately, the text views Maritain's framework as a flawed, historically conditioned compromise that deeply influenced modern Catholic social teaching (such as Vatican II's Dignitatis humanae), but lacks the timeless validity of classical natural law
Maritain does not grasp St. Thomas's view, simply remarking that in antiquity and the Middle Ages the natural law was focused on obligations rather than rights. 100 In the absence of criteria for determining their scope, the rights postulated by Maritain are in effect no more than a list of desirable objectives to be pursued. Maritain distinguishes between rights that can be limited by the demands of the common good, and those that are inalienable. He does not offer criteria for distinguishing between the two, and the examples of inalienable rights that he gives-those of life and the pursuit of happiness-do not have any evident characteristics that identify them as being inalienable, except for their having been so described in the American Declaration of Independence (no doubt a reflection of Maritain's sojourn in America). One need not labor the point that this account of natural law and natural rights does not stand up to examination. In addition to its influence on Vatican ...
