The development of the notion of continuous physical quantity is traced from Aristotle to Aquinas to Suarez. It is concluded that Aristotle’s divisibility definition fails to excavate the ontological core of material quantification. Although the basic germ of the solution to the problem is discovered in Aquinas, it is Suarez who fully articulates the essence of continuous physical quantity with his explicit concept of aptitudinal extension — which has crucial theological implications. Résumé Nous considérons ici le développement de la notion (...) de quantité physique continue, d’Aristote à Thomas d’Aquin à Suarez. Nous concluons que la définition d’Aristote en termes de divisibilité ne parvient pas à dégager le noyau ontologique de la quantification matérielle. Encore que le germe fondamental de la solution au problème soit découvert par Thomas d’Aquin, c’est Suarez qui articule pleinement l’essence de la quantité physique continue, grâce à son concept explicite d’extension « aptitudinale » — dont les implications théologiques sont cruciales.

The article titled The pearl of the ‘Pro-Life’ movement? Reflections on the Kermit Gosnell controversy is a thoughtful piece in which the author raises some important questions, including those impinging on the motivations and apparent inconsistencies of the more vocal officials of the more visible segments of a vast and somewhat diverse grass-roots social uprising.1The pro-life movement has indeed showcased the Gosnell trial, but not because many of its members actually believe that gestational age is a morally relevant criterion. In (...) fact, there is probably a nearly uniform desideratum among the most influential groups to abolish all induced abortion from the first moment of conception, even if that goal logically also requires a ban on all potentially abortifacient contraceptives .2 Even the umbrella National Right to Life Committee with its 50 state affiliates, many of which have been criticised for their incremental approach to ending elective abortion,3 holds that ‘a new individual human being begins at fertilisation, when the sperm and ovum meet to form a single cell.’4 There is no practical necessity to split temporal or geographical hairs about when or how far the sperm must enter the ovum for formal union to occur, because the process is virtually inexorable once it starts, and is, thence, confined to a short span of time and space.Nor are the pro-life leaders being ‘disingenuous’ in their focal interest on this particular case. The underlying motivation is not to go delving for a mere ‘pearl’ , but rather to dive into some deep metaphysical waters about the …. (shrink)

In his contribution to the Journal of Medical Ethics, Joseph Mazor1 makes a logical case, based on the premises underlying his reasoning, for his article's primary thesis: he concludes that parents have the prerogative to determine the ‘best interests’ of their infant son in a circumcision decision. If the facts of the matter were ultimately no different from what he adduces, one could admit the soundness of his argument. But the paper is flawed by some questionable assumptions and grievous incompleteness.First, (...) the author insufficiently explores the profound implications of a serious equivocation in the term ‘circumcision’ that is common throughout the literature. He does superficially reference the article on ‘Circumcision’ in The Jewish Encyclopedia, which describes in detail the actual steps involved in brit milah versus brit periah.2 Despite this general allusion, though, he hardly discusses the matter further, as though the distinction were practically irrelevant. It does have fundamental import, however. Milah is merely a token clip of the very tip of the prepuce, which leaves most of the organ system intact. This was evidently the version practiced in biblical times under the old Abrahamic–Mosaic covenant, before the Talmudic guardians of Judaic ethnic and religious identity proposed a means to prevent Hellinising Jewish men from attempting foreskin restoration by stretching their remaining preputial tissue forward. The rabbis mandated the replacement of milah with the more drastic procedure of periah, a radical surgery that cuts and tears from the penis its entire covering, leaving the glans irreversibly denuded. Unlike traditional milah, the innovation of periah necessarily has significant adverse consequences .Second, Mazor concedes that circumcision might cause a ‘moderate’ reduction of sexual pleasure in the lad's ….

In this dissertation I put forth a defense of liberalism understood in terms of the principle of state neutrality. In the first half of the dissertation, I attempt to show that a commitment to state neutrality is a central element running through the liberal tradition. I argue for this by examining closely the liberal theories offered by Locke, Mill, Hobhouse, and Rawls. In the second part, I defend liberal neutrality against two prominent criticisms: first, that it is flawed because it (...) cannot acknowledge the importance of certain distinctive virtues needed for a flourishing human life; second, that it fails to account for the importance of civic virtues in citizens and so leads to serious sustainability problems for liberal societies. I conclude that liberal neutrality, properly understood, can withstand both of these criticisms and offers a viable and attractive model of political association. (shrink)

The ethical propriety of routine male infant circumcision has been debated in journals of medicine and law for many years. This article explores the issue from historical, medical, and moral perspectives. Two essentially different forms of circumcision (one more drastic than the other) are distinguished. Discussion focuses on the effects of the more radical kind of nontherapeutic surgery on a normal healthy child’s body: whether it constitutes a mutilation, whether it is medically warranted, and whether it is ethically defensible in (...) light of general philosophical principles and Catholic moral doctrine. The conclusion questions the social bias favoring parental choice to circumcise a non-consenting son. National Catholic Bioethics Quarterly 12.1 (Spring 2012): 99–128. (shrink)

This study consists of a series of steps toward the development of a general theory of differences in ontological kind. The first part defines the notion of a "logical individual" and argues for its role as the basic ontological unit. I also take issue with those who hold that 'exist' is equivocal, as well as with those who claim that category-mistakes lack a truth-value. This part concludes with the "existence criterion", according to which a thing exists just in case it (...) is a logical individual; examples of things which satisfy and things which fail to satisfy this criterion are discussed. ;The second part covers a number of topics related to the classification of things into kinds. Problems involved in such classification are considered, including a discussion of whether, and on what grounds, certain attributes may be better qualified to define kinds than are others. The idea of ontological kinds is also adumbrated in an intuitive fashion, and a "formalist" strategy for ontological kinds, under which no attribute is treated as more ontologically puissant than any other, is considered and discarded. ;In the last part the ideal of substance is employed as a way of mediating between individuals, on the one hand, and privileged kinds, on the other. Following an examination of substance in Aristotle, six senses of substance are distinguished, of which two are found to hold particular promise for the development of a theory of ontological kinds. Discussion of these two notions of substance includes critiques of "stuff" metaphysics as well as "Aristotelian essentialism". The latter is found to depend on an unwarranted assumption that certain individuals are not only referentially, pragmatically, or psychologically prior to others, but also ontologically privileged. Refutation of this assumption leads to a rehabilitation of Aristotle's notion of "prime matter", but also to a picture of substance closer to Descartes' than to Aristotle's. The arguments against Aristotelian substance finally suggest an account of ontological kinds in terms of the possibility or impossibility of "fusion"--the coinstantiation by two individuals of a single individual concept.

Task shifting is increasingly used to address human resource shortages impacting HIV service delivery in low- and middle-income countries. By shifting basic tasks from higher- to lower-trained cadres, such as Community Health Workers, task shifting can reduce overhead costs, improve community outreach, and provide efficient scale-up of essential treatments like antiretroviral therapies. Although there is rich evidence outlining positive outcomes that CHWs bring into HIV programs, important questions remain over their place in service delivery. These challenges often reflect concerns over (...) whether CHWs can mitigate HIV through a means that does not overlook the ethical and practical constraints that undergird their work. Ethical and practical guidance thus needs to become the cornerstone of CHW deployment. This paper analyzes such challenges through the lens of Ethical Principlism. We examined papers identifying substantive and ethical challenges impacting CHWs as they provide HIV services in low- and middle-income contexts. To do this, we analyzed papers written in English and published from year 2000 or later. These articles were identified using MEDLINE, Cochrane Database of Systematic Reviews, and Google Scholar databases. In total, 465 articles were identified, 78 of which met our inclusion criteria. Article reference lists and grey literature were also examined. CHWs experience specific challenges while carrying out their duties, such as conducting emotionally- and physically-demanding tasks with often inadequate training, supervision and compensation. CHWs have also been poorly integrated into health systems, which not only impacts quality of care, but can hinder their prospects for promotion and lead to CHW disempowerment. As we argue, these challenges can be addressed if a set of ethical principles is prioritized, which specifically entail the principles of respect for persons, justice, beneficence, proportionality and cultural humility. CHWs play a crucial role in HIV service delivery, yet the ethical challenges that can accompany their work cannot be overlooked. By prioritizing ethical principles, policymakers and program implementers can better ensure that CHWs are combatting HIV through a means that does not exploit or take their critical role within service delivery for granted.

Worldwide there are substantial differences within and between countries in aggression and violence. Although there are various exceptions, a general rule is that aggression and violence increase as one moves closer to the equator, which suggests the important role of climate differences. While this pattern is robust, theoretical explanations for these large differences in aggression and violence within countries and around the world are lacking. Most extant explanations focus on the influence of average temperature as a factor that triggers aggression, (...) or the notion that warm temperature allows for more social interaction situations in which aggression is likely to unfold. We propose a new model, CLimate, Aggression, and Self-control in Humans, that helps us to understand differences within and between countries in aggression and violence in terms of differences in climate. Lower temperatures, and especially larger degrees of seasonal variation in climate, call for individuals and groups to adopt a slower life history strategy, a greater focus on the future, and a stronger focus on self-control. The CLASH model further outlines that slow life strategy, future orientation, and strong self-control are important determinants of inhibiting aggression and violence. We also discuss how CLASH differs from other recently developed models that emphasize climate differences for understanding conflict. We conclude by discussing the theoretical and societal importance of climate in shaping individual and societal differences in aggression and violence. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Really statistical explanation is a hitherto neglected form of noncausal scientific explanation. Explanations in population biology that appeal to drift are RS explanations. An RS explanation supplies a kind of understanding that a causal explanation of the same result cannot supply. Roughly speaking, an RS explanation shows the result to be mere statistical fallout.

Should a principle of charity be applied to the interpretation of the colour concepts exercised in visual experience? We think not. We shall argue, for one thing, that the grounds for applying a principle of charity are lacking in the case of colour concepts. More importantly, we shall argue that attempts at giving the experience of colour a charitable interpretation either fail to respect obvious features of that experience or fail to interpret it charitably, after all. Charity to visual experience (...) is therefore no motive for resisting the natural, Galilean response to a scientific understanding of light and vision. The best interpretation of colour experience ends up convicting it of widespread and systematic error. (shrink)

We present data and argument to show that in Tetris - a real-time interactive video game - certain cognitive and perceptual problems are more quickly, easily, and reliably solved by performing actions in the world rather than by performing computational actions in the head alone. We have found that some translations and rotations are best understood as using the world to improve cognition. These actions are not used to implement a plan, or to implement a reaction; they are used to (...) change the world in order to simplify the problem-solving task. Thus, we distinguish pragmatic actions ñ actions performed to bring one physically closer to a goal - from epistemic actions - actions performed to uncover information that is hidden or hard to compute mentally. To illustrate the need for epistemic actions, we first develop a standard information-processing model of Tetris-cognition, and show that it cannot explain performance data from human players of the game - even when we relax the assumption of fully sequential processing. Standard models disregard many actions taken by players because they appear unmotivated or superfluous. However, we describe many such actions that are actually taken by players that are far from superfluous, and that play valuable roles in improving human performance. We argue that traditional accounts are limited because they regard action as having a single function: to change the world. By recognizing a second function of action - an epistemic function - we can explain many of the actions that a traditional model cannot. Although, our argument is supported by numerous examples specifically from Tetris, we outline how the one category of epistemic action can be incorporated into theories of action more generally.

The purpose of this paper is to apply Aristotle''s theory of causation to the administrative realm in an attempt to provide the manager/student with a more complete basis for organizational analysis. The authors argue that the traditional approach to administrative case studies limits the manager''s/student''s perspective to the positivistic world view at the expense of a more encompassing perspective which can be achieved through the use of an Aristotelian approach. Aristotle''s four-part theory of causation is juxtaposed with contemporary views of (...) organizational ideology/philosophy, culture, climate and leadership, and staff or personnel. The Mazda automobile plant in Flat Rock, Michigan is provided as a sample case study to demonstrate the comprehensiveness of the Aristotelian method in organizational contexts. (shrink)

This commentary focuses on the parts of psychological game theory dealing with preference, as illustrated by team reasoning, and supports the conclusion that these theoretical notions do not contribute above and beyond existing theory in understanding social interaction. In particular, psychology and games are already bridged by a comprehensive, formal, and inherently psychological theory, interdependence theory (Kelley & Thibaut 1978; Kelley et al. 2003), which has been demonstrated to account for a wide variety of social interaction phenomena.

Biblical Christianity should be a powerful, life-forming, paradigm-shifting experience leading to increasing levels of Christlikeness. Unfortunately, the experience of many Christians today is far short of the transformation described in Scripture. This article reports on a portion of mixed-methods research examining the transformative learning reported by alumni of a 22-lesson discipleship process called the Immersion Experience by Aphesis Group Ministries. Holistic spiritual health involves listening to our emotions, confronting toxic shame, addressing childhood defenses, and untangling our distorted spirituality.

A total of 80 authors working in a variety of scientific disciplines commented on the theoretical model of CLimate, Aggression, and Self-control in Humans. The commentaries cover a wide range of issues, including the logic and assumptions of CLASH, the evidence in support of CLASH, and other possible causes of aggression and violence. Some commentaries also provide data relevant to CLASH. Here we clarify the logic and assumptions of CLASH and discusses its extensions and boundary conditions. We also offer suggestions (...) for future research. Regardless of whether none, some, or all of CLASH is found to be true, we hope it will stimulate future research on the link between climate and human behavior. Climate is one of the most presing issues of our time. (shrink)

The dispute between realists about color and anti-realists is actually a dispute about the nature of color properties. The disputants do not disagree over what material objects are like. Rather, they disagree over whether any of the uncontroversial facts about material objects--their powers to cause visual experiences, their dispositions to reflect incident light, their atomic makeup, and so on--amount to their having colors. The disagreement is thus about which properties colors are and, in particular, whether colors are any of the (...) properties in a particular set that is acknowledged on both sides to exhaust the properties of material objects. In a previous paper we discussed at length one attempt to identify colors with particular properties of material objects--namely, with their dispositions to cause visual experiences. Here we shall discuss a different and perhaps more influential version of realism, which says that the colors of material objects are microphysical properties of their surfaces. We shall call this theory physicalism about color (physicalism, for short). In order to evaluate this theory, however, we shall first have to clarify some methodological issues. Our hope is that we can bring some further clarity to the question of color realism, whether or not we succeed in our critique of the physicalists' answer. (shrink)

Die Leitgedanken meiner Untersuchungen über die Grundlagen der Mathematik, die ich - anknüpfend an frühere Ansätze - seit 1917 in Besprechungen mit P. BERNAYS wieder aufgenommen habe, sind von mir an verschiedenen Stellen eingehend dargelegt worden. Diesen Untersuchungen, an denen auch W. ACKERMANN beteiligt ist, haben sich seither noch verschiedene Mathematiker angeschlossen. Der hier in seinem ersten Teil vorliegende, von BERNAYS abgefaßte und noch fortzusetzende Lehrgang bezweckt eine Darstellung der Theorie nach ihren heutigen Ergebnissen. Dieser Ergebnisstand weist zugleich die Richtung (...) für die weitere Forschung in der Beweistheorie auf das Endziel hin, unsere üblichen Methoden der Mathematik samt und sonders als widerspruchsfrei zu erkennen. Im Hinblick auf dieses Ziel möchte ich hervorheben, daß die zeit weilig aufgekommene Meinung, aus gewissen neueren Ergebnissen von GÖDEL folge die Undurchführbarkeit meiner Beweistheorie, als irrtüm lich erwiesen ist. Jenes Ergebnis zeigt in der Tat auch nur, daß man für die weitergehenden Widerspruchsfreiheitsbeweise den finiten Stand punkt in einer schärferen Weise ausnutzen muß, als dieses bei der Be trachtung der elementaren Formallsmen erforderlich ist.

Music is a natural human expression present in all cultures, but the functions it serves are still debated. Previous research indicates that rhythm, an essential feature of music, can enhance coordination of movement and increase social bonding. However, the prolonged effects of rhythm have not yet been investigated. In this study, pairs of participants were exposed to one of three kinds of auditory stimuli (rhythmic, arrhythmic, or white‐noise) and subsequently engaged in five trials of a joint‐action task demanding interpersonal coordination. (...) We show that when compared with the other two stimuli, exposure to the rhythmic beat reduced the practice effect in task performance. Analysis of the behavioral data suggests that this reduction results from more temporally coupled motor movements over successive trials and that shared exposure to rhythm facilitates interpersonal motor coupling, which in this context serves to impede the attainment of necessary dynamic coordination. We propose that rhythm has the potential to enhance interpersonal motor coupling, which might serve as a mechanism behind its facilitation of positive social attitudes. (shrink)

The material contained in the following translation was given in substance by Professor Hilbertas a course of lectures on euclidean geometry at the University of G]ottingen during the wintersemester of 1898-1899. The results of his investigation were re-arranged and put into the formin which they appear here as a memorial address published in connection with the celebration atthe unveiling of the Gauss-Weber monument at G]ottingen, in June, 1899. In the French edition, which appeared soon after, Professor Hilbert made some additions, (...) particularly in the concludingremarks, where he gave an account of the results of a recent investigation made by Dr. Dehn.These additions have been incorporated in the following translation.Geometry, like arithmetic, requires for its logical development only a small number ofsimple, fundamental principles. These fundamental principles are called the axioms ofgeometry. The choice of the axioms and the investigation of their relations to one anotheris a problem which, since the time of Euclid, has been discussed in numerous excellentmemoirs to be found in the mathematical literature.1 This problem is tantamount to thelogical analysis of our intuition of space.
