Dans un premier temps de son oeuvre, Georges Duby n’évoque qu’incidemment l’univers religieux féminin, avec quelques allusions au rôle de Robert d’Arbrissel ou d’Abélard. Frôlant le sujet dans Le Chevalier, la femme et le prêtre (1981), il n’aborde de front les rapports des femmes et de la religion que dans les premier et troisième volumes des Dames du XIIe siècle (1995-1996). Se refusant à reléguer les femmes dans le seul champ religieux, c’est pourtant bien là qu’il trouve les ferments qui (...) expliquent l’intérêt qui leur est porté vers 1100 et qui débouche, vers 1180, sur une considération sociale accrue. Il trace de surcroît les pistes permettant de cerner le mouvement de féminisation du religieux qui caractérise les derniers siècles du Moyen Âge. (shrink)

İslâm ilim geleneğinde Hz. Peygamber’e ait olanla olmayan bilginin sahih bir şekilde tespit edilmesi büyük önem arz etmektedir. Bu bağlamda haberlerin doğruluğunu ve güvenilirliğini belirlemek için çeşitli metodolojiler geliştirilmiştir. Hanefî fukahâsı, bu metodolojiler arasında kendine özgü bir yaklaşım benimsemiş ve haber-i vâhidlerin kabul edilebilirliğini dört temel ölçüt üzerinden değerlendirmiştir. Bu dört asıldan birisi de sahâbe ihticâcına arz prensibidir. Hanefî usulcüler, sahâbe arasında bir konuda ihtilaf çıktığında o konuyla alakalı rivâyetin ihtilaf anında delil olarak sunulmamasını o haberin makbul olmadığının alameti olarak (...) değerlendirmişlerdir. Hanefîlerin benimsemiş olduğu bu prensip oryantalistlerin e silentio/sessizlik delilini çağrıştırttığı ifade edilmektedir. e Silentio delili “Bir hadisin belirli bir zaman diliminde bulunmadığını ispatlamanın en iyi yolu, eğer hadis gerçekten o dönemde mevcut olsaydı, o dönemdeki fıkhî tartışmalarda delil olarak kullanılması gerektiği halde kullanılmadığını ortaya koymaktır” şeklinde açıklanmıştır. Bu sebeple Hanefî usûlcülerin bu haber-i vâhid tenkit kriterinden neyi kastettiklerinin, bunun nasıl anlaşılması ve uygulandığının doğru bir şekilde tespit edilmesi gerekmektedir. Çalışmanın en önemli amacı ise bu prensibin e silentio deliliyle ilişkisi ve karşıtlıklarının ortaya çıkarılmasıdır. Bu sebeple araştırmada hem literatür taraması hem de mukayeseli bir yöntem takip edilmiştir. Hanefî usûl eserleri ve e silentio delilini daha çok kullanan Schacht (1902-1969) ve Juynboll’un (1935-2010) eserleri çalışmanın ana kaynaklarını oluşturmaktadır. Cessâs'tan (ö. 370/981) itibaren bu asla atıfta bulunan Hanefî usûlcülerin bakış açıları incelendiğinde, her iki delilin görünüşte benzer yaklaşımlar sergilediği düşünülse de ayrıntılarda farklı amaçlara sahip oldukları sonucuna ulaşılmıştır.

Assumindo que o “tornar-se cristão” é o eixo que sustenta toda a produção literária de Søren Kierkegaard, o escopo deste ensaio é tentar delinear o conceito de paixão apresentado em Temor e Tremor como uma condição necessária para a efetivação dos movimentos dialéticos que possibilitam o desenvolvimento da fé. Efetivamente, é através do pseudônimo Johannes de Silentio que Kierkegaard apresenta sua ode à fé. Neste sentido, é sobre o esteio da narrativa apresentada em Temor e Tremor acerca da fé (...) demonstrada por Abraão (quando Deus solicitou-lhe a vida de Isaac em sacrifício) que destacaremos a importância que o mencionado pseudônimo atribui à paixão como fundamento que precede e, substancialmente, compõe a fé última: aquela que só emerge ante ao absurdo, mas que, uma vez conquistada, assoma como possibilidade para a fuga do desespero da existência e para a construção de sentido para a vida humana.

The main scientific problems of chemical bonding were solved half a century ago, but adequate philosophical understanding of chemical combination is yet to be achieved. Chemists routinely use important terms ("element," "atom," "molecule," "substance") with more than one meaning. This can lead to misunderstandings. Eliminativists claim that what seems to be a baseball breaking a window is merely the action of "atoms, acting in concert." They argue that statues, baseballs, and similar macroscopic things "do not exist." When macroscopic objects like (...) baseballs move, exceedingly large numbers (1025) of microscopic components coordinate their activities. Understanding how this happens requires attention to the interactions that link parts into larger units. Eliminativists say that everything that truly exists has causal relationships in addition to those of its components—"nonredundant causality." This paper holds that if a number of entities interact in such a way that the effect of that collection on test objects is different than it would have been in the absence of the interaction, then identification of that collection as a single composite agent is warranted, for purposes to which that difference is relevant. Ordinary "chemical substances" (both elementary materials such as dihydrogen and compounds such as water) fulfill this version of the requirement of nonredundant causality. Other sorts of chemical coherences, including chemical dissipative structures (e.g., flames), also fulfill that criterion. All these types of coherences qualify as "substances" (as that term is used in philosophy) even though they are not all "chemical substances.". (shrink)

This study examines the self-reported ethics of both current and future advertising practitioners, and compares their responses to four scenarios and 17 statements on advertising ethics. Stepwise discriminant analysis was used to determine the extent to which both groups applied the classical ethical theory of deontology to the scenarios and statements. Results indicate significant differences between both groups. For example, current advertising practitioners are significantly less likely than future practitioners to apply deontology to decision making. The implications of these results (...) are discussed and suggestions for future research are outlined. (shrink)

We show that every infinite computable partial ordering has either an infinite Δ 0 2 chain or an infinite Π 0 2 antichain. Our main result is that this cannot be improved: We construct an infinite computable partial ordering that has neither an infinite Δ 0 2 chain nor an infinite Δ 0 2 antichain.

In [3] F. P. Ramsey proved as a theorem of Zermelo-Fraenkel set theory (ZF) with the Axiom of Choice (AC) the following result:(1) Theorem. Let A be an infinite class. For each integer n and partition {X, Y} of the size n subsets of A, there exists an infinite subclass of A all of whose size n subsets are contained in only one of X or Y.

A distinction is drawn between the "outcome", Or result of a certain exercise of power, And the "act", Or the manner in which that result is accomplished. Omnipotence is then defined solely in terms of its possible outcomes, And the definition used to dispel certain "paradoxes" recently discussed in articles by j l mackie, P t geach and r g swinburne, Among others. Finally, It is argued that god's inability to do certain things, Such as telling a lie or breaking (...) a promise, Is not incompatible with his omnipotence. (shrink)

Business ethics is the continuing process of re-defining the goals and rules of business activity. In times of rapid change, spurred equally by technological innovation within the business community and by societal expectations in the larger community, participants who share in that process of re-defining goals and rules should be sensitive to professional differences. Lawyers and executives, for instance, while seeking a common societal good, will utilize measurably different goals and methods based on differences in leadership style, accountability to constituents (...) and client relationship generally. Because of these differences, definitions of what is ethical will vary as well, spread across a spectrum of ethicality. (shrink)

A phenomenalist philosophy which employs the Principle of Acquaintance (PA) plus the Principle that what exists are the referents of certain meaningful terms, defined by PA, cannot include either universals or particulars in its ontology, but is limited to instances of universals as constituting the range of ontological existents. Universals must be omitted since they are repeatable and, hence, never wholly presented or contained, whereas the objects of direct acquaintance are wholly and exhaustively presented. Furthermore, no entities beyond characters (qualities (...) and relations) are given in direct acquaintance; hence, particulars, too, must be omitted for the phenomenalist who relies on PA. (shrink)

Frank E. Zachos offers a comprehensive review of one of today's most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts found (...) in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name ("species") is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.

Upshot: In view of Kenny’s clinical insights, Hug’s notes on the intricacies of rational vs. a-rational “knowing” in the design sciences, and Chronaki & Kynigos’s notice of mathematics teachers’ meta-communication on experiences of change, this response reframes the heuristic power of bisociation and suspension of disbelief in the light of Kelly’s notion of “as-if-ism” (constructive alternativism. Doing as-if and playing what-if, I reiterate, are critical to mitigating intra-and inter-personal relations, or meta-communicating. Their epistemic status within the radical constructivist framework is (...) cast in the context of mutually enriching conversational techniques, or language-games, inspired by Maturana’s concepts of “objectivity in parenthesis” and the multiverse.

I invoke the conceptual machinery of contemporary possible-world semantics to provide an account of the metaphysical status of "bridge laws" in intertheoretic reductions. I argue that although bridge laws are not definitions, and although they do not necessarily reflect attribute-identities, they are supervenient. I.e., they are true in all possible worlds in which the reducing theory is true.

The Kyoto Protocol on global warming has provoked great controversy in part because it calls for heavier burdens on wealthy countries than on developing countries in the effort to control climate change. The U.S. Senate voted unanimously to oppose any agreement that does not require emissions reductions in low-income countries. The ethics of this position are examined in this paper which shows that there are good moral reasons for supporting the provisions of the Kyoto Protocol. Such a conclusion follows easily (...) from considerations of distributive justice but can also be supported by more narrowly self-interested arguments. (shrink)

Encore un livre sur saint Thomas, dira-t-on. Que pourrait ajouter celui-ci à tout ce qui existe déjà? Nous voudrions d'abord dans cet ouvrage répondre simplement mais en vérité, et en lisant les textes eux-mêmes de saint Thomas et d'Aristote, à certaines objections ou lieux communs entendus ou lus plus ou moins régulièrement, qui empêchent de commencer à vouloir connaître la pensée de frère Thomas. Il s'agit de mettre en évidence la grande richesse, pour l'intelligence et le coeur humains, de sa (...) pensée philosophique, de ses analyses, de ses manières de poser les questions et d'interroger le réel. Un préambule pour une introduction à la philosophie de Thomas, telle est essentiellement l'intention de ces quatre études et non pas une introduction à la philosophie thomasienne purement et simplement. Elles cherchent ainsi à définir l'esprit d'un apprentissage philosophique qui a aussi en lui tout ce qui convient pour aider à un apprentissage théologique et spirituel, mystique même. (shrink)

In this paper we investigate some families of decision problems associated with a restricted class of Post canonical forms, specifically, those defined over one-letter alphabets whose productions have single premises and contain only one variable. For brevity sake, we call any such form an RPCF (Restricted Post Canonical Form). Constructive proofs are given which show, for any prescribed nonrecursive r.e. many-one degree of unsolvability D, the existence of an RPCF whose word problem is of degree D and an RPCF with (...) axiom whose decision problem is also of degree D. Finally, we show that both of these results are best possible in that they do not hold for one-one degrees. (shrink)

A constructive proof is given which shows that every nonrecursive r.e. many-one degree is represented by the family of decision problems for partial implicational propositional calculi whose well-formed formulas contain at most two distinct variable symbols.

A critical study of McPeck's recent book, in which he strengthens and develops his arguments against teaching critical thinking (CT). Accepting McPeck's basic claim that there is no unitary skill of reasoning or thinking, I argue that his strictures on CT courses or programs do not follow. I set out what I consider the proper justification that programs in CT have to meet, and argue both that McPeck demands much more than is required, and also that it is plausible that (...) this deflated justification can be met. Specitically, I argue that it is reasonable to expect transfer of learning for basic logical skills. Additional topics covered include: the relation ofliberal education to critical thinking, argument analysis, testing for CT, and the value of conceptual or linguistic analysis. (shrink)
