Although most natural law ethical theories recognize moral absolutes, there is not much agreement even among natural law theorists about how to identify them. The author argues that in order to understand and determine the morality (or immorality) of a human action, it must be considered in relation to the organized system of human practices within which it is performed. Such an approach, he argues, is to be found in the natural law theory of Thomas Aquinas, especially once it is (...) recognized that the logical structure of Aquinas's ethical theory is basically that of an Aristotelian science. In order to depict this structure and to explain how it bears upon the analysis of action, the author investigates a number of issues that have attracted the attention of Thomistic and Aristotelian scholarship. He examines the nature of practical reason, its relationship with theoretical reason, the derivation of lower from higher ethical principles, the incommensurability of human goods, the relationship between will and intellect, and the principle of double effect. The book will be useful to students and scholars interested in ethics, especially from an Aristotelian and/or Thomistic perspective. One appendix reproduces the Leonine text of the De malo (question 6), with facing English translation. Another appendix provides facing Latin text and English translation of the Summa Theologiae I-II (question 94, article 2). ABOUT THE AUTHOR: Kevin L. Flannery, S.J., author of many works on the history of logic--particularly Aristotelian logic--is dean of the faculty of philosophy and professor of the history of ancient philosophy at the Pontifical Gregorian University in Rome. PRAISE FOR THE BOOK: ""I know of no more careful and detailed study of Thomas's principle that the realms of theoretical and practical rationality are parallel. This principle is indeed central to an understanding of Thomas Aquinas's ethical thought, and Father Flannery examines its ramifications most perspicaciously. His book constitutes a valuable and important addition to the Thomistic literature. Father Flannery's writing is lucid, if not always extremely engaging, and his arguments are well supported by references to, and quotations from, the Aristotelian and Thomistic texts upon which they are based.""--The Medieval Review ""It would be hard to overstate the importance of this book at the present juncture of Thomistic studies.""--Ralph McInerny, University of Notre Dame "" . . . of interest and of great value mostly to specialists in Aquinas's ethics or moral theory more generally. Flannery presents complex matters clearly, and his explanations of the logical presuppositions of Aquinas's moral thought are always illuminating.""--Jean Porter, Theological Studies ""This is a significant work that belongs on the bookshelf of any serious student of Aquinas. . . . An important contribution to Thomistic studies.""--Irish Theological Quarterly ""This scholastic text will particularly appeal to thinkers interested in Aristotelian mathematics and logic and their practical integration into Thomistic natural law ethics. However, all natural law scholars must address the questions of context and method raised by Flannery's insights and his careful, precise textual analyses."" -- Beverly Whelton, Review of Metaphysics.

Decisions about withdrawing or continuing life-sustaining treatments are often not made in a reasoned manner: those who must make the decisions are often not sure what would constitute an upright decision and, therefore, doubt the correctness of the decisions they have made or are about to make. Making use especially of what Thomas Aquinas says about omissions , this article attempts to establish some principles regarding when and why one might morally withdraw life-sustaining treatments, regarding the grounds on which a (...) family might resist a doctor's decision to withdraw treatment and regarding other related issues.

An examination of traditional sources for the Roman Catholic under-standing of marriage reveals that the ends of marriage might be ordered differently, given different contexts. This permits one working within that tradition to see marriage as a political and cultural entity existing independently of the individuals who participate in it. Marriage is also the standard with respect to which sexual activity is judged to be proper or not, a standard that applies to all human beings by virtue of their rational (...) nature. Understanding this allows one to understand how some people, including some of the mentally handicapped, might legitimately be prevented from marrying and even from engaging in genital sexual activity. It also allows one to solve some theoretical difficulties regarding contraception and homosexuality and connected with the fact that sterile couples cannot procreate and yet are permitted to marry.

The author offers, first, an account of St. Thomas Aquinas’s Aristotelian-inspired understanding of the object of a moral act and of what morally that species contributes to the act of which it is a part. Then, with special attention to two passages in Aquinas cited frequently by the proponents of the new natural law theory—that is, Summa theologiae 2-2.64.7 and the commentary on Peter Lombard’s Sentences 2.40.1.2—the author argues that a close analysis of Aquinas’s remarks on objects and intentions does (...) not support the claim that the new natural law theory is Thomistic.

This article considers M. Therese Lysaught’s analysis of an apparent abortion that occurred in Phoenix, Arizona, in 2009. Since Lysaught invokes it, the article considers Rev. Martin Rhonheimer’s theory about the bearing of vital conflict situations on the object of the act performed. A vital conflict situation is present when, for instance, the life of a mother might be spared if her fetus is aborted, otherwise she and the fetus will die. The article argues that the use of such situations (...) in this way by Lysaught and Rhonheimer is incompatible with Church teaching. The article concludes by suggesting that certain cases might be analyzed in such a way that the mother’s life is saved and the fetus dies but there is no direct abortion.

The author considers, first of all, recent and fairly recent interpretations of Plato’s dialogue the Crito, arguing that the character Socrates, whose expressed ideas probably correspond in major detail to the convictions of the historical Socrates, is not saying that the laws of Athens demand unquestioning obedience. The dialogue is rather an account of the debate that goes on in Socrates’s mind itself. A strong consideration in this debate is clearly the rule of law; but equally strong is Socrates’s lifelong (...) commitment to carry out what, in the end, he regards as the most reasonable course of action. The author then considers two contemporary ethical issues: our way of coming to know the natural law and the proper understanding of laws that allow of exceptions. Regarding the first, he argues—consistently with what we find not only in the Crito but also in Aristotle and Thomas Aquinas—that we come to know the natural law through being immersed in the laws and customs of a particular society: the more just the society, the better access to the natural law it provides. Regarding the second, he argues that an article in Aquinas is sometimes interpreted as suggesting that the realm of concrete human experience is beyond the reach of law. He argues, in the spirit of the historical Socrates, that the rule of law is equivalent to the rule of reason and that this does reach into the realm of concrete human experience, where exceptions are sometimes recognized as contained in the law.

The purpose of this essay is to explain what the terms “formal cooperation” and “material cooperation” mean in the thought of St. Alphonsus Liguori, who is a pivotal figure in the Church’s tradition of reflection on cooperation and is often referenced when the distinction between formal and material cooperation in evil is discussed. The author explains why—and to some extent when—mainstream Catholic moralists who associate themselves with Alphonsus speak of some cooperation as formal and other cooperation as material. Specifically, he (...) discusses two factors that are essential for the analysis of cooperation in evil— the meaning of the term “formal” and the role of “segments of intelligibility” in determining what is material rather than formal cooperation.
