Nucleation and motion of kink pairs on partial dislocations are examined by elasticity theory for materials with a high Peierls stress. Two approaches are used: one considers the change in average stacking-fault energy due to alloying elements and the other considers the change in local SFE due to a nearby solute atom. Both approaches highlight the role of SFE on kink nucleation, propagation and annihilation and both furnish strain rate as a function of stress, temperature and SFE. Model predictions are (...) compared with yield stress data for two systems: firstly, an intermetallic, MoSi 2 , which softens for alloying elements that decrease the SFE and hardens for Re additions that increase the SFE; secondly, a ceramic oxide, MgO-Al 2 O 3 spinel, which softens with increasing addition of excess alumina and at the same time exhibits a decrease in SFE. The average SFE approach agrees qualitatively with the data while quantitative agreement is obtained with the local SFE approach. The possibility is considered that the model applies to other materials, such as TiAl, HfV 2 and Fe 3 Al, which show softening with certain alloying additions. One requirement is that the dislocations are dissociated more than a few atomic distances; otherwise kink nucleation occurs on the perfect dislocation . Hence the model does not apply to materials such as bcc metals which only have a core dissociation. Normal hardening effects of solutes from size and modulus misfits are additive with any softening effects from a decrease in SFE and so may mask the latter, as occurs for W additions to MoSi 2.

OBJECTIVE: This article describes a method for investigating attitudes towards prioritisation in medicine. SETTING: University of Kuopio, Finland. DESIGN: The method consisted of a set of 24 paired scenarios, which were imaginary patient cases, each containing three different ethical indicators randomly selected from a list of indicators (for example, child, rich patient, severe disease etc.). The scenarios were grouped into 12 random pairs and the procedure was repeated four times, resulting in 12 scenario pairs arranged randomly in five different sets. (...) SURVEY: This method was tested with four groups of subjects (n = 8, n = 47, n = 104 and n = 36). RESULTS: Children and patients with a severe disease were prioritised in all groups. The aged, patients with a mild disease and patients with a self-acquired disease were negatively prioritised in all groups. Poor or rich patients were prioritised in some groups but negatively prioritised in others. CONCLUSIONS: The validity and reliability of this method are good and it is suitable for investigating attitudes towards medical prioritisation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Trinity by Thomas Joseph White, O.P.:A Model of Living ThomismSerge-Thomas Bonino O.P."The human being naturally seeks wisdom." From the very first line of the magisterial work we are dealing with, Fr. Thomas Joseph White's 2022 The Trinity: On the Nature and Mystery of the One God, it is all about wisdom. Wisdom was already at the heart of a previous work by Fr. White devoted to the natural (...) theology of St. Thomas, his 2009 Wisdom in the Face of Modernity. Wisdom is more than the accumulation of information or the juxtaposition of knowledge. It is an eminent form of knowledge that, on the one hand, involves the person of the thinker in all its dimensions, intellectual, emotional, existential, and on the other, seeks to understand its object in the light of the most fundamental causes, which are simultaneously the most enlightening and explanatory principles because they are the most universal. The Trinity: On the Nature and Mystery of the One God is undoubtedly a work of wisdom. Fr. White grasps the entire Christian mystery from its Trinitarian source, since, as we shall see, the entire Mystery (in the Pauline sense of the economy of salvation in Jesus Christ as the fulfillment of the Father's benevolent purpose) is at the same time rooted in the eternal mystery of the triune God and makes it known to us as it unfolds its truth and saving power in time.But the sapiential nature of the object studied has some effect on the form of the work itself. Indeed, if Fr. White were not Rector Magnificent of the Angelicum, he would be a magnificent architect, because he possesses a sense of order to the highest degree and knows how to introduce unity in diversity. The presentation of The Trinity is perfectly structured, and therefore very [End Page 461] clear and didactic. Among many other factors that create its unity, I was especially interested in the highlighting of what the philosopher André de Muralt calls "structures of thought": similarities of proportionality between the ways in which authors from even very different theological epochs have treated a problem.1 I am thinking for instance of how Fr. White shows the strong structural similarities between contemporary Trinitarian theologies and the three types of medieval Trinitarian theology (the Franciscan, the Thomist, and the Nominalist). "My claim here is that the modern Trinitarian tradition tends to reproduce various elements of the medieval traditions, … albeit in creative and unexpected ways" (399). So it is a conceptually well-unified work, and where there is unity, there is being, goodness and beauty.The introduction, as I said, is placed under the sign of wisdom. Fr. White takes up there the neo-Scholastic theme of the "three wisdoms": philosophical wisdom, theological wisdom, and mystical wisdom.2 The book's perspective is explicitly that of theological wisdom, as a scientific form of the intelligence of faith, but (we shall return to this point in connection with the place given to philosophy) it puts into practice in an exemplary manner the collaboration, without confusion or separation, between the three wisdoms.3My purpose, of course, is not, nor can it be, to "summarize" the contents of a book of more than seven hundred pages, which manages to be both a comprehensive handbook for higher theological education and a true personal theological essay. I will therefore limit myself to highlighting three partial but significant aspects.(1) The first is the explicit and overt Thomistic character of the book (see 6–7). The Trinity is in fact a vibrant plea in favor of the relevance of the theology of St. Thomas, as indicated by the very last sentence:The Church today can and should still have recourse to the theology of Thomas Aquinas, and to the living Thomistic tradition, as a privileged means of interpreting and advancing her own understanding of the mystery of God.(690) [End Page 462]The Trinity is the demonstration in actu exercito of the truth of this concluding statement. I therefore propose to reflect, in the first part of my paper, on the nature of Fr. White's Thomism, which depends, as we... (shrink)

In the national religious studies there was a tendency to know the origins of national spirituality. Such treatment is required by all those processes that take place in the cultural and religious plane of our country. Religious scholars are working to find their own original manifestations of Ukrainian spirituality, while at the same time seeking identification with a particular tradition. This is precisely the task of finding the national content of Ukrainian spiritual heritage. Let's try to do this on the (...) example of Ukrainian Orthodox preaching culture - a phenomenon that originated in the seventeenth century and had its continuation in several generations of Ukrainian preachers.

At the end of the Middle Ages, the friar Dominican Peter Schwarz wrote The shield of the Thomists. It is a handly book of philosophy in which he presents the main thesis of thomist school, between them is the theory of active intellect.

This book explores the role of Aristotelian concepts, principles, and themes in Thomas Aquinas's theology. Each of the ten essays investigates the significance of Aquinas's theological reception of Aristotle in a central theological domain: the Trinity, the angels, soul and body, the Mosaic law, grace, charity, justice, contemplation and action, Christ, and the sacraments. In general, the essays focus on the Summa theologiae, but some range more widely in Aquinas's corpus. Readers will become acquainted with Aquinas's theological uses of the (...) great Aristotelian themes, such as act and potency, God as pure act, substance and accidents, power and generation, change and motion, fourfold causality, form and matter, hylomorphic anthropology, the structure of intellection, the relationship between knowledge and will, happiness and friendship, habits and virtues, contemplation and action, politics and justice, the best form of government, and private property and the common good.

Evaluating the role and opportunities of state correction of the functions of religious organizations, it must be recognized that the state is not able to administratively change those trends and forms of activity that express the social purpose of religious associations and organizations.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Nature as Guide: Wittgenstein and the Renewal of Moral Theology by David Goodill, O.PCajetan Cuddy and O.P.Nature as Guide: Wittgenstein and the Renewal of Moral Theology. By David Goodill, O.P. Washington, D.C.: The Catholic University of America Press, 2022. Pp. xiii-319. $75.00. (hardcover). ISBN: 978-0-8132-3445-8.Nature as Guide is an intriguing reevaluation of the philosophical legacy of Ludwig Wittgenstein in the light of Thomistic moral theology after the Second (...) Vatican Council. Goodill helpfully lays out his fundamental argument in the book’s introduction: Wittgenstein can help the philosopher to reconcile the “modern dichotomy between nature and reason,” and the theologian to reevaluate “the associated oppositions typical of modern thought, such as that between moral agency and natural agency or between grace and nature” (2). The author is overt in his appreciation for Fergus Kerr’s 1997 monograph Theology after Wittgenstein. Nonetheless, Nature as Guide is unique insofar as it focuses on specifically moral theological issues in a moment of theological “renewal”—one in which we can recognize “the restoration of metaphysics to the center of theological debate” (12).The first four chapters of Nature as Guide consider Wittgenstein in relation to themes associated with classical philosophy. Goodill’s “objective in the first part of the book is to construct a dialogue between Wittgenstein and the metaphysical tradition which illuminates both conversation partners” (38). This initial part of the book culminates in an account of human nature that serves as the foundation for the moral theological inquiry that follows in the second part (the fifth through the eighth chapters).In the first chapter (“What Lies Hidden: Wittgenstein, Metaphysics, and Moral Theology”), Goodill introduces Wittgenstein’s “philosophical practice”—specifically his “insistence on grounding philosophical enquiry in everyday thinking” that effectively “connects him to the [metaphysical] tradition that begins with Plato and Aristotle” (16). Goodill is perceptive and nuanced in his analysis of Wittgenstein’s texts. He recognizes that “it would be wrong to treat [Wittgenstein] as an unproblematic inheritor of this tradition” (37). Nonetheless, he wants his readers to appreciate the careful balance between theory and praxis maintained in Wittgenstein’s thought vis-à-vis the priorities of classical philosophy. To this end, he examines G. E. M. Anscombe’s account of how Wittgenstein helped her to overcome the “trap” of phenomenalism.In the second chapter (“Nature, Logic, and Grammar”), Goodill attends to the progress of key tenets in Wittgenstein’s philosophy. He identifies as “the guiding theme” of this narrative “the development of Wittgenstein’s understanding of the relationship between the meaning and the application of linguistic expressions” (40–41). Specifically, he suggests that Wittgenstein’s “mistake” in the Tractatus (51) can be reduced a fundamental point: the erroneous presupposition that there is “one general notion of clarity which is required in all contexts. It was precisely this requirement which Wittgenstein came later to reject in the Investigations” (52). Indeed, between the Tractatus [End Page 703] and the Investigations Wittgenstein abandoned his efforts to establish a “forced unity” of language through “the general form of the proposition”—turning, instead, to “our actual linguistic practices” (85). The whole of human life, thus, “provides the unity of our grammar” (ibid.). Nonetheless, Goodill also points out that Wittgenstein does not reject “the central insight” of the Tractatus, namely, “that meaning is internal to our forms of representation” (59). This immanence remains throughout the Tractatus and the Investigations.The third chapter (“Grammar, Teleology, and Understanding”), summarizes objections to Goodill’s proposal that Wittgenstein can be read in continuity with the metaphysical tradition. William Charlton “argues that in the absence of a teleological conception of nature Wittgenstein’s account of language collapses into pragmatism” (88-89). Rush Rhee “accuses Wittgenstein of being misled by his analogy between language and games to neglect the basis of our linguistic practices in the human search for universal understanding” (89). In brief, both “Charlton and Rhee argue that a much richer conception of our natural human capacities and reactions is required than that provided by Wittgenstein”—and they do so in a complementary way (103). Although Goodill does not believe that their objections stand above... (shrink)

The Brain Death Reconsidered – Is It a Tenable Concept? Since 1968 it has been recognized in the medical practice that irreversible coma connected with apnea can serve as a criterion of human death. This approach was first introduced in the so called Harvard Protocol. As a result of the work of this commission, the brain-based criteria of human death were quickly legally introduced in America and in most countries in the world. The only symptom on which death can be (...) pronounced is, according to this new definition, the absence of spontaneous brain function. However, the acceptance of the new definition of death did not eliminate the old one completely. In many states both old and new definitions of death are legally valid. Practically, in these countries the alternative definition of death functions alongside the old one and diagnosis of death can be based both on the cardiac/respiratory and brain symptoms. One of the few exceptions proved to be Japan. The law in this country does not provide a uniform answer to the question of what human death is. Instead, it allows people to choose between traditional death and brain death. The law states that if a person wants to be an organ donor after brain death has occurred, he or she must record that intention on a donor card or label beforehand. Those who object to brain death and transplantation do not need donor cards. They are considered to be alive until the heart stops beating. In this way the Japanese law respects the opinion of 20-40% of the society who do not believe in the brain death. The opinion of the same percentage of people in Western societies who oppose BD is ignored by their legal systems. Initially the concept of BD did not cause a lot of controversy but this situation changed in the nineties of the last century. Since then many authors have criticized the validity of the brain-based criteria of death. They maintain that it is impossible to declare the absence of all the functions of the whole brain on the basis of the clinical tests supposed to detect it. There may be present some level of consciousness in brain death (BD) patients and therefore, they may feel pain. It is significant that 27% of the members of the teams which perform the excision of the heart for transplantation think that they are killing a living person and that in many countries during this operation a normal general anesthesia is required because of the vivid reaction of the body of the patient. The opponents of the brain death theory stress that the accurate examination of the so-called brain dead persons shows the persistence of the functions of significant parts of their brains. There are EEG waves recorded in 20-40% of BD patients. Event related potentials (ERP) show the reaction to verbal and non-verbal stimuli and the hormone production by the brain tissue can be detected in many BD people. The proper treatment could not only significantly prolong lives of the BD patients, but around 60% of possible donors with the lowest result of 3 in Glasgow Coma Scale could be restored to normal life if their brain edema is properly treated. This treatment should be based on the therapeutic hypothermia connected with the application of the thyroid hormones, whose level is usually too low in the patients with the brain injury. There is a growing lack of consensus regarding the issue of brain death, especially among physicians. Some regard brain death as a biological one, some as the death of the person but not of the human body, and the rest, as a definition accepted by the society, which doesn’t require other legitimacy than the freely chosen criteria. The brain death concept is also criticized from the philosophical point of view. The strength of the brain death theory was based on the premise that the brain is the integrating center of the body. According to this argument, the death of the brain means that the organism ceases to exist for it is no longer a functioning whole. To this argument the opponents of the brain death concept say that this question is not a question a priori but an empirical one and that the empirical data validate the opposite opinion, which says that the bodies of brain dead patients are alive. Some widely known cases show that even the real death of the entire brain means the death of the body and, therefore, may not signify the death of a human person. The integration of the body is the function of the organism as a whole and not of a single organ, even if this organ is the brain. This point of view can be confirmed by the opinion of St. Thomas Aquinas who says that the soul is primarily and per se connected with the body as a whole as the proportionate perfectible and only secondarily with the parts of the body, according to their ordination to the whole. So, the death of any single organ does not preclude the union of the soul with the rest of the body as a living whole. Moreover, the terms such as “consciousness” and “person” should not be identified. The term such as “human living nonpersons”, proposed by some bioethicists and referring to the people without consciousness has not been accepted in the official documents concerning BD. Bodies of the BD people are alive, therefore, it is not right to use the term “brain death” to describe the state of these patients, but rather the term “brain failure” should be used. As the result, according to some authors, the dead donor rule should be abolished. The Catholic Church stresses the sacredness of the human life from the beginning to the end. Therefore She requires that there be no doubts that the donor in BD is really dead. Because of the lack of consensus among physicians, philosophers and theologians, the popes John Paul II and Benedict XVI decided to continue the scientific research and discussion concerning BD between the representatives of various disciplines. Keywords: brain death, brain edema, global ischemic penumbra, therapeutic hypothermia, consciousness, person, substantial form. (shrink)

Andrey Bely was an important member of the Russian symbolist movement of the late 19th and early 20th centuries. This essay presents a summary of the development of his ideas regarding the origins of image and symbol in poetic language. For Bely language organizes chaos. The poet finds images in the internal world of dreams. Music has an organizing power beyond that of language, which language attempts to imitate. Under the influence of Vladimir Solovyov he looked to the union of (...) Divine Wisdom or Sophia with the Eternal Logos as the principle behind symbolic images. Later, under the spell of Rudolf Steiner, he found the source of inspiration in the eternal dwelling of the Logos from which the human ego descends into flesh. The task of the poet is to recover the memory of the time before he left the realm of the Logos and to return to that realm by participating in Christ's ascent to the Cross. The autobiographical novel Kotik Letaev gives an account of recovering memory from before birth and the need to be joined with Christ crucified. (shrink)

In this paper I weigh in on the ongoing Thomistic debate between corruptionists, survivalists, and incompletionists about whether the soul's separate, post-mortem existence suffices for my post-mortem existence.

Dans le contexte d’une mondialisation qui n’est pas sans ambiguïtés ni opacités, il convient d’examiner à quelles conditions pluralisme culturel et pluralisme religieux sont des chances pour un humanum plus authentique. Le consensus porté par la Déclaration universelle des droits de l’homme pourrait réorienter le dialogue interreligieux et le nourrir alors que les religions suscitent aujourd’hui un certain scepticisme. Quant au message évangélique, en résonance profonde avec l’attente légitime de plus d’humanité, il porte en lui une capacité de résistance, plus (...) forte que la crise institutionnelle et culturelle des Églises.

Dans cet article, le théologien dominicain propose une sorte de biographie intellectuelle qui recoupe l’évolution de la théologie catholique durant les quarante dernières années. Héritier de la tradition intellectuelle dont Marie-Dominique Chenu fut l’initiateur dans son ouvrage, Une École de théologie: le Saulchoir, il explique comment, tout en restant fidèle à la posture théologique de Thomas d’Aquin, il a pris peu à peu ses distances vis-à-vis de la théologie thomiste en tant que théologie métaphysique. En charge à la suite d’Henri (...) Bouillard de la chaire de théologie fondamentale de l’Institut Catholique de Paris, il a cherché à définir celle-ci comme une science herméneutique qui assure la crédibilité du message chrétien à partir d’une corrélation critique entre l’expérience de la communauté chrétienne primitive et l’expérience historique des hommes et des femmes d’aujourd’hui. Il précise alors les conséquences de ce tournant herméneutique de la théologie tant pour la relecture des Écritures que pour la réinterprétation de la tradition théologique et dogmatique. En conclusion, dans la fidélité à l’orientation herméneutique de sa théologie, il fait état de ses principales options dans le chantier toujours ouvert de la théologie des religions ou mieux du pluralisme religieux.

Bounded PAC substructures of models of stable theory T are generalizations of bounded PAC fields and bounded PAC beautiful pairs generalize Poizat's beautiful pairs. Both notions were introduced in the authors Ph.D. thesis. In this paper, we prove that under the assumption that the PAC property is first order for T, the theory of any bounded PAC structure is simple. Moreover, if the PAC property is first order for T and T does not have the finite cover property, then the (...) theory of any bounded PAC beautiful pair is simple. We, also, give a characterization of dividing in both cases. (shrink)

This article provides a critical appraisal of the case for healthcare being rationed away from older patients to those who are younger. After sketching a metaphysics of elderliness and reviewing clinical and economic cases for healthcare rationing, the article looks in depth at the most challenging case for age rationing known as the ‘fair innings’ case. This article rejects that case and makes an alternative case that fairness actually dictates against age rationing in favour of allocation on the basis of (...) need. It concludes with a call for a renewed ‘covenant between generations’, founded on the virtue of pietas. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Where Do Substantial Forms Come From?—A Critique of the Theistic Evolution of Mariusz Tabaczek*Michael Chaberek O.P. and Monika Metlerska-ColerickIntroductionThe question posed in the present article is whether it is possible to be a proponent of theistic evolution and, at the same time, of the metaphysical [End Page 239] principles elaborated by St. Thomas Aquinas. The authors of Thomistic Evolution: a Catholic Approach to Understanding Evolution in the Light of (...) Faith, recently published in Polish, imply that Aquinas's doctrine was not only compatible with the idea of biological macroevolution, but also—on some level—endorsed it.1 In his "Afterword" to the above publication, Mariusz Tabaczek points out certain deficiencies in the argumentation provided by its authors, simultaneously underlining that he agrees with the book's principal thesis.I will not examine the book by the American Dominicans in this article because I have already addressed their arguments in full in my book entitled Aquinas and Evolution,2 where I demonstrated that it is impossible to be both a proponent of theistic evolution and a follower of the philosophical views proposed by St. Thomas. In his "Afterword," Tabaczek presents a contradictory thesis. He claims that being both of the above is possible, provided that one modifies St. Thomas's teaching in four "essential aspects." The very approach of this kind already raises doubts. After all, if St. Thomas's doctrine indeed needs to be modified in order to reconcile his thought with evolution, it suggests that, in fact, it cannot be reconciled with it. Therefore, perhaps the problem comes down to asking whether the four points of incompatibility indicated by Tabaczek really constitute an "essential" part of Aquinas's doctrine? If it is not the case, they might be omitted or modified. If, however, they relate to certain essential elements of Aristotelian-Thomistic metaphysics, disregarding them equals denying St. Thomas's teaching and, consequently, makes it impossible to reconcile it with theistic evolution.In order to settle the problem, I devote the first part of my article to determining whether the points presented by Tabaczek refer to the essential elements of Aquinas's discourse. In the second part of my text, however, I move to a more important point, namely the fact that theistic evolution encounters many more problems in the context of Thomistic metaphysics. Since I have already addressed this matter in several places,3 I limit the scope [End Page 240] of the second part of my article to only one such problem: the emergence of new substantial forms (new species) via the mechanism of evolution. Thus, the object of the present analysis is to examine whether the solution suggested by Tabaczek provides an explanation to the problem of the origin of new substantial forms in theistic evolution.Commentary on the Four Points of IncompatibilityAccording to Tabaczek, the teaching of St. Thomas can be reconciled with theistic evolution under the conditions of:(1) recognizing the possibility of the emergence of new species, that is, acknowledging that the perfection of the universe can increase every day not only in terms of the number of individual beings, but also as regards the number of species; (2) emphasizing the fact that God's initial act of creation is limited to the derivation of matter of the lowest degree of complexity out of nothing (ex nihilo); (3) recognizing the fact that the processes of chemical, biochemical, and biological evolution belong to the work of adornment (opus ornatus), whose subsequent stages spread out across the entire history of the universe and, therefore, are not limited to a finished and past time period; and finally (4) acknowledging that God's direct intervention in the creation of the first representatives of plant and animal species (with the exception of man) is not necessary.4Ad (1) and ad (3). Points 1 and 3 boil down to the same idea, since they are both concerned with the fact that evolution continues, whereas from the Christian perspective, the divine work of creation had already finished. Therefore, if one adopts theistic evolution, the Christian truth of God completing his creative work with the creation of man has to be rejected. The... (shrink)

The twentieth century was a period of prolonged crisis of spirituality in the Soviet Union. The atheist state used all possible and impossible levers of various influences on religious associations and ordinary believers. Since the assertion of the Soviet authorities, an open war has been declared against any manifestation of religion. There were real battles: with their ideological fronts, offensives and retreats, the whole system of operations developed and the tactical plan in line with the party-approved strategy. The result of (...) such disputes between the state and its believing citizens has been the church crises, schisms, and even the elimination of entire denominations. The most violent was the struggle against religious organizations disloyal to the Soviet authorities. It should be noted that even external loyalty did not save religious associations from the onslaught of anti-Sovietism. (shrink)
