This study of three central themes in the logic of Alexander of Aphrodisias, the greatest of the ancient Aristotelian commentators, provides insight not only into Aristotle's logical writings but also into the tradition of scholarship which they spawned.

Aristotle’s treatment of mixed, first-figure, problematic-assertoric syllogisms has generated a good deal of controversy among modern commentators.I argue that W.D.Ross’s criticism of A.Becker’s cr...

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.

Written for non-specialists, this concise and accessible work by moral philosopher Kevin L. Flannery engages in a careful reflection of the moral issues of greatest importance in the lives of Christians today. After introductory chapters on the relationship between ethics and church teaching, and on the relevance of action theory--the study of the nature and structure of human actions--Flannery applies Aristotle's and Thomas Aquinas's theory of human action to the following topics: sexual morality, reproduction, killing and keeping (...) alive, cooperation in the evil acts of others, and conscience. The book treats a number of controversial issues, not so much because they are controversial, but because they usefully explain the philosophical principles underlying church teaching. Flannery considers, for example, whether it is moral for a spouse who has contracted a disease such as HIV or AIDS to make use of a prophylactic during sexual intercourse. Flannery also addresses whether it is moral for a politician to vote in favor of legislation that permits same-sex marriage, or for a family or doctor to withdraw nutrition and hydration from a patient in a vegetative state. A major theme discussed throughout the book is intention and its effect on the moral character of human acts. ABOUT THE AUTHOR: Kevin L. Flannery, S.J., professor of philosophy at the Pontifical Gregorian University in Rome, is author of many works on ethics and on the history of logic, including Acts Amid Precepts: The Aristotelian Logical Structure of Thomas Aquinas's Moral Theory (CUA Press).

In lieu of an abstract, here is a brief excerpt of the content:Contradiction and Legislation Regarding the Right to LifeKevin L. Flannery, S.J.Unborn Human Life and Fundamental Rights: Leading Constitutional Cases under Scrutiny. Edited by Pilar Zambrano and William Saunders, with concluding reflections by John Finnis. Berlin: Peter Lang, 2019.The most fundamental principle of law is the principle of non-contradiction. This is Thomas Aquinas's position in the seminal article on the natural law, Summa theologiae I-II, question 94, article 2, (...) where, citing Aristotle, he formulates the principle as, "One should not simultaneously affirm and negate." Lafter in the same article, Thomas offers a practical formulation of the same principle, "Good is to be done and pursued and evil avoided"; but in law, since it is contained in propositions (airmations and negations) as distinct from ideas regarding the pursuit of goods, the prior formulation is the more immediately relevant of the two.The book under review is important in that, by going through the legal history regarding abortion and related issues in a number of different countries—the United States, Canada, Italy, Spain, Poland, Ireland (Eire), Costa Rica, Argentina, Chile, Mexico, and Peru—it causes to emerge any number of times the realization that legislation and judicial decisions in favor of abortion "rights" invariably infect a legal system with contradictions and inconsistencies of various sorts. The present essay is, therefore, not your typical book review. Its objective is simply to list some of the legal contradictions and inconsistencies identified by the book's various authors as they describe the legal status of the unborn in their respective nations. [End Page 1323]William Saunders's very clear and comprehensive first chapter is entitled, "Judicial Interference in the Protection of Human Life in the United States: Actions and Consequences." In it, he describes, among other things, the Human Cloning Prohibition Act passed by the U.S. House of Representatives in 2003, which prohibited "any person or entity, public or private" from performing human cloning (23). He speaks also of a bill proposed in the U.S. Senate once the Human Cloning Prohibition Act had passed in the House of Representatives. This Senate bill (which was entitle, "The Human Cloning Ban and Stem Cell Research Protection Act") would have prohibited "any person or other legal entity" from conducting human cloning, even while allowing nuclear transplantation, which it defines as "transferring the nucleus of a human somatic cell into an oocyte from which the nucleus... ha[s] been... removed or rendered inert." The problem here, as Saunders explains, is that this latter definition "is the very definition of cloning" (25). In other words, in the same year, two pieces of legislation were considered in the Congress of the United States, both purporting to ban human cloning, one of which would have permitted what the other described (correctly) as human cloning and so prohibited.In the second chapter, "Whither United States Abortion Law?" by Gerard V. Bradley, discussed, among other things, is the inconsistency between the United States Supreme Court's pro-abortion decision Roe v. Wade and various laws, both state and federal, prohibiting feticide. Bradley says of the 2004 federal Unborn Victims of Violence Act that, "in pertinent part it says that 'whoever' 'causes the death of or bodily injury to,' a 'child who is in utero' is guilty of an offense apart from any accompanying offense against the woman carrying the child." The penalty for such an act is the same as would be imposed if the act were inflicted upon the unborn child's mother: if, for instance, the mother was killed. "A child in utero," reports Bradley, "is defined as a member of the species homo sapiens, at any stage of development, who is carried in the womb'" (37).The problem here is that prosecutable under this law are acts identical with those performed legally by abortionists. Bradley mentions two cases in which a woman's male partner—in one case the woman's husband—effected by stealth the abortion of her child. In one case, the male purchased abortion pills and affixed to their container a pharmacy label indicating that it contained a common antibiotic; in the other, the husband obtained the same type of...

Contemporary society very often asks of individuals and/or corporate entities that they perform actions connected in some way with the immoral actions of other individuals or entities. Typically, in the attempt to determine what would be unacceptable cooperation with such immoral actions, Christian scholars and authorities refer to the distinction, which appears in the writings of Alphonsus Liguori, between material and formal cooperation, the latter being connected in some way with the cooperator's intention in so acting. While expressing agreement with (...) most of Alphonsus's determinations in these regards, Cooperation with Evil also argues that the philosophical background to these determinations often lacks coherence, especially when compared to related passages in the writings of Thomas Aquinas. Having compared the philosophical approaches of these two great moralists, Cooperation with Evil then describes a number of ideas in Thomas's writings that might serve as more effective tools for the analysis of cases of possible immoral cooperation. The book also includes, as appendixes, translations of relevant passages in both Alphonsus and Thomas. (shrink)

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.

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 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 (but not sole) 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.

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.

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 (and possibly others) 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.

White matter tracts are known to be susceptible to injury following concussion. The objective of this study was to determine whether contact play in sport could alter white matter metabolite levels in female varsity athletes independent of changes induced by long-term exercise. Metabolite levels were measured by single voxel proton magnetic resonance spectroscopy in the prefrontal white matter at the beginning and end of season in contact and non-contact varsity athletes. Sedentary women were scanned once, at a time equivalent to (...) the Off-Season time point. Metabolite levels in non-contact athletes did not change over a season of play, or differ from age matched sedentary women except that non-contact athletes had a slightly lower myo-inositol level. The contact athletes had lower levels of myo-inositol and glutamate, and higher levels of glutamine compared to both sedentary women and non-contact athletes. Lower levels of myo-inositol in non-contact athletes compared to sedentary women indicates long-term exercise may alter glial cell profiles in these athletes. The metabolite differences observed between contact and non-contact athletes suggest that non-contact athletes should not be used as controls in studies of concussion in high-impact sports because repetitive impacts from physical contact can alter white matter metabolite level profiles. It is imperative to use athletes engaged in the same contact sport as controls to ensure a matched metabolite profile at baseline. (shrink)

The performance of 93 children aged 3 and 4 years on a battery of different counterfactual tasks was assessed. Three measures: short causal chains, location change counterfactual conditionals, and false syllogisms—but not a fourth, long causal chains—were correlated, even after controlling for age and receptive vocabulary. Children's performance on our counterfactual thinking measure was predicted by receptive vocabulary ability and inhibitory control. The role that domain general executive functions may play in 3- to 4-year olds' counterfactual thinking development is discussed.

Lists of species underpin many fields of human endeavour, but there are currently no universally accepted principles for deciding which biological species should be accepted when there are alternative taxonomic treatments (and, by extension, which scientific names should be applied to those species). As improvements in information technology make it easier to communicate, access, and aggregate biodiversity information, there is a need for a framework that helps taxonomists and the users of taxonomy decide which taxa and names should be used (...) by society whilst continuing to encourage taxonomic research that leads to new species discoveries, new knowledge of species relationships, and the refinement of existing species concepts. Here, we present 10 principles that can underpin such a governance framework, namely (i) the species list must be based on science and free from nontaxonomic considerations and interference, (ii) governance of the species list must aim for community support and use, (iii) all decisions about list composition must be transparent, (iv) the governance of validated lists of species is separate from the governance of the names of taxa, (v) governance of lists of accepted species must not constrain academic freedom, (vi) the set of criteria considered sufficient to recognise species boundaries may appropriately vary between different taxonomic groups but should be consistent when possible, (vii) a global list must balance conflicting needs for currency and stability by having archived versions, (viii) contributors need appropriate recognition, (ix) list content should be traceable, and (x) a global listing process needs both to encompass global diversity and to accommodate local knowledge of that diversity. We conclude by outlining issues that must be resolved if such a system of taxonomic list governance and a unified list of accepted scientific names generated are to be universally adopted. (shrink)

In the last 25 years, Roman Catholic moral theology has debated issues ranging from the sources of moral theology to the role of ecclesiastical authority in moral theology. In 1993, Pope John Paul II issued his encyclical letter Veritatis Splendor, which addresses issues in fundamental moral theology. The encyclical must be understood against the background of ongoing debates since Pope Paul VI's 1968 encyclical on birth control (Humanae Vitae). It is not clear what the impact of Veritatis Splendor will be. (...) However, it seems safe to say that it will be deployed in debates about issues such as birth control, artificial reproduction, sterilization, and abortion. (shrink)

In 1994, the National Conference of Catholic Bishops revised the "Ethical and Religious Directives for Catholic Health Care Services." A goal of the Directives is to maintain the moral integrity of Catholic health care institutions and to address controversies in bioethics and health care. The Directives represent a shift to an exclusively principle-based approach to moral reason. This shift threatens to undermine the very tradition that the bishops seek to protect.

Disorder and suffering are increasing significantly in our society. Violent crime, unemployment, escape through drug-taking are all on the increase. It is apparent, also, that much of this disorder and suffering, and the anxiety it fosters, is rooted in science and its technological off-spring. The un-employment produced by a micro-technology is only one small example. It is also apparent that one of the principal foundation stones for the scientific enterprise was Christianity.

BackgroundThe Patient-Centered Outcomes Research Institute is obligated to peer review and to post publicly “Final Research Reports” of all funded projects. PCORI peer review emphasizes adherence to PCORI’s Methodology Standards and principles of ethical scientific communication. During the peer review process, reviewers and editors seek to ensure that results are presented objectively and interpreted appropriately, e.g., free of spin.MethodsTwo independent raters assessed PCORI peer review feedback sent to authors. We calculated the proportion of reports in which spin was identified during (...) peer review, and the types of spin identified. We included reports submitted by April 2018 with at least one associated journal article. The same raters then assessed whether authors addressed reviewers’ comments about spin. The raters also assessed whether spin identified during PCORI peer review was present in related journal articles.ResultsWe included 64 PCORI-funded projects. Peer reviewers or editors identified spin in 55/64 submitted research reports. Types of spin included reporting bias, inappropriate interpretation, inappropriate extrapolation of results, and inappropriate attribution of causality. Authors addressed comments about spin related to 47/55 of the reports.Of 110 associated journal articles, PCORI comments about spin were potentially applicable to 44/110 articles, of which 27/44 contained the same spin that was identified in the PCORI research report. The proportion of articles with spin was similar for articles accepted before and after PCORI peer review.DiscussionJust as spin is common in journal articles and press releases, we found that most reports submitted to PCORI included spin. While most spin was mitigated during the funder’s peer review process, we found no evidence that review of PCORI reports influenced spin in journal articles. Funders could explore interventions aimed at reducing spin in published articles of studies they support. (shrink)

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.
