An implication is a proposition, a consequence is a relation between propositions, and an inference is act of passage from certain premise-judgements to another conclusion-judgement: a proposition is true, a consequence holds, whereas an inference is valid. The paper examines interrelations, differences, refinements and linguistic renderings of these notions, as well as their history. The truth of propositions, respectively the holding of consequences, are treated constructively in terms of verification-objects. The validity of an inference is elucidated in terms of the (...) existence of a chain of immediately evident steps linking premises and conclusion. (shrink)

The paper offers an interpretation of thesis 6.01. The treatment touches upon variables, identity, elementary propositions, internal relations. Klammerausdrücke, and operations. Wittenstein's notations are found not to cover the particular form of definition by induction that is used at 6 and 6.01. It is concluded that Wittgenstein's ability to design of a formal system of logic does not match his outstanding logico-philosophical insight.

The purpose of this paper is to show how a MacIntyre-inspired business school could contribute to developing practical wisdom in students through its curriculum, methods, faculty, student selection criteria, and governance. Despite MacIntyre's critiques, management can be presented, in MacIntyrean terms, as a second-order, domain-relative practice, with practical wisdom as corresponding virtue. Management education consists in developing practical wisdom. How? Primarily by initiating students and enabling them to participate in communal traditions of inquiry focused on, although not limited to, the (...) purposes and ends of business. The transmission of objective knowledge, analytical skills, and techniques is subordinated to the end goal. We consider traditions centered on shareholder value maximization, the balancing of stakeholder interests, and the fulfillment of the common good of firms. Each gives rise to a particular kind of business school. A MacIntyrean business school is one that seeks the common good of firms. (shrink)

This book brings together philosophers, mathematicians and logicians to penetrate important problems in the philosophy and foundations of mathematics. In philosophy, one has been concerned with the opposition between constructivism and classical mathematics and the different ontological and epistemological views that are reflected in this opposition. The dominant foundational framework for current mathematics is classical logic and set theory with the axiom of choice. This framework is, however, laden with philosophical difficulties. One important alternative foundational programme that is actively pursued (...) today is predicativistic constructivism based on Martin-Löf type theory. Associated philosophical foundations are meaning theories in the tradition of Wittgenstein, Dummett, Prawitz and Martin-Löf. What is the relation between proof-theoretical semantics in the tradition of Gentzen, Prawitz, and Martin-Löf and Wittgensteinian or other accounts of meaning-as-use? What can proof-theoretical analyses tell us about the scope and limits of constructive and predicative mathematics? (shrink)

We investigate the emergence of iconicity, specifically a bouba-kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of participant dyads who played an interactive communicative game and individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend (...) to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection. (shrink)

Ventricular Fibrillation is responsible for a majority of sudden cardiac death, but little is known about how ventricular tachycardia (VT) degenerates into ventricular fibrillation. Several clinical studies focused only on preventing VT with a class III antiarrhythmic drug resulted in many deaths. Our simulations investigate the interactions between an antiarrhythmic drug likely to suppress a VT and a Figure 8 reentry. A parameter AAR is introduced to increase the action potential duration and therefore simulate various Class III drugs. Simulations are (...) ran under several conditions (phases of the reentry, values of AAR, durations). They show that a VT can be suppressed whatever the phase of the reentry but it strongly depends on the duration of the effect. It confirms that a drug which can suppress a reentry can also worsen it. It also shows a great variety of activation patterns and thus the complexity of antiarrhythmic drugs effects. Simulations also demonstrate that suppressing VT is an increasing function of AAR.

It was an afternoon in the early stages of the pandemic when Lisa Richardson and I ran into each other at the hospital coffee line. Standing six feet apart and decked out in masks, scrub caps, and face shields, we were almost unrecognizable to one another and to ourselves. The pandemic was of course top of mind, but our conversation quickly turned to what was being articulated about the pandemic and why it was being heralded as a "disaster for feminism". (...) As Audre Lorde reminds us, "There is no such thing as a single-issue struggle because we do not live single issue lives," and we were beginning to see how many issues intersected in the pandemic moment. The United Nations was calling... (shrink)

Then, as soon as my column was safely submitted, hot new results on antigravity appeared. The lead article in the January 6, 1986 issue of Physical Review Letters had the unassuming title: "A Reanalysis of the Eötvös Experiment" by E. Fischbach, et al. Two days later the New York Times ran an article with the headline: "Hints of Fifth Force in Universe Challenge Galileo's Findings" describing the importance of Fischbach's work. Peculiar experimental results from terrestrial gravity measurements and from the (...) behavior of "strange" K-mesons (kaons) had been explained by a new theory proposing a "hypercharge" force, a new fifth force of nature which is gravity-like but which repels rather than attracting nearby masses. This new antigravity force is the subject of this AV column. (shrink)

About 22 years ago, the physics world was briefly rocked by claims of evidence for a new “5 th force”, based on reanalysis of data from an early 20 th century experiment. Baron Roland von Eötvös, a Hungarian nobleman, had performed extensive measurements of the correlation between inertial mass and gravitational mass and published them in 1922. The lead article in the January 6, 1986 issue of Physical Review Letters had the unassuming title: "A Reanalysis of the Eötvös Experiment" by (...) Ephriam Fischbach, et al. Two days later the New York Times ran an article with the headline: "Hints of Fifth Force in Universe Challenge Galileo's Findings" describing the possible implications of Fischbach's work. (shrink)

In “The Free-Will Intuitions Scale and the Question of Natural Compatibilism,” Deery, Davis, and Carey recommend that experimental philosophers employ a new methodology for determining the extent to which the folk are natural compatibilists about free will and moral responsibility. While I agree that the general methodology that the authors developed holds great promise for improving our understanding of folk attitudes about free will and moral responsibility, I am much less enthusiastic about some of the conclusions that they reached on (...) the basis of the particular studies they ran. Key among these are that the folk harbor some compatibilist intuitions and that the findings of both Nichols and Knobe , on the one hand, and Nahmias and Murray , on the other, are undermined by their reliance upon a particular formulation of determinism in the cases they presented to their subjects.

The new G?ndh?r? manuscript finds from Afghanistan and Pakistan, which date from approximately the first century BCE to the third or fourth century CE, are the earliest manuscript witnesses to the literature of the Indian Buddhist nik?yas or schools. They preserve texts whose parallels are found in the various Tripi?akas, or what remains of them, preserved in other languages and belonging to various nik?yas, including sections of?gamas such as the Ekottarik?gama and Vana-sa?yutta of the Sa?yutta-nik?ya/Sa?yukt?gama and anthologies of such s?tras, (...) besides many texts that are not generally classed as "canonical", such as commentaries. These very early collections of texts raise questions concerning canon-formation, such as whether the Gandh?ran communities that produced these manuscripts had fixed?gama collections and closed canons or whether this material witnesses a stage in which collections and canons were still relatively fluid and open, and whether these manuscripts, which span several centuries, witness a shift towards fixity. This paper addresses these issues and re-examines our understanding of the formation of the canons of the early Indian nik?yas in light of the new G?ndh?r? manuscript finds. (shrink)

The lettering of this inscription begins at the very top of the block, just below the straight edge, and stops half-way down the block, the lower part being smoothed but uninscribed. As the inscription is not set centrally on the block, it is probably the continuation of an inscription which ran on a block once superimposed upon it. Doubtful letters are those which are marked by the dot underneath; and W. Peek reported in Ath. Mitt. lxvi, 200 n. 2, that (...) he had seen the top of the v which Vollgraff suggested in the restorationThe inscription is dated to the seventh century B.C. by epigraphists. The stone itself was seen in 1729 by Fourmont and rediscovered in 1928 by Vollgraff; it was in the wall of a Venetian tower on the Larissa or acropolis of Argos. No one knows whence the Venetians had taken it. Therefore Vollgraff's suggestion that it had originally been set up in porta arcis regiae is no more than an attractive speculation. (shrink)

Bu araştırma, din öğretiminde, şükür kavramı örnekliğinde, herhangi bir kavramın, değerin, duygunun, tutumun, halin, bir varoluş durumunun öğretilmesine yönelik öğreticiye rehberlik edebilecek bir bakış açısına dikkat çekme çabasındadır. Bu bakış açısının temelinde, dini metinlerdeki bilginin, öğrenenin yaşantısı ile buluşması yer almaktadır. Öğrenenin kendini bu buluşmalar yoluyla keşfetmeye devam etmesi ve yeni öğrenmeler yoluyla dönüşmesi süreçlerinin, öğreticinin dini bilgiyle oluşturacağı içeriğe dair bakış açısıyla doğrudan ilgili olduğu düşünülmektedir. Bu makalede şükür kavramı hakkında Tefsir ve Hadis alanlarının kendi yöntem ve kaynakları kullanılarak (...) bir içerik sunulmaktadır. Öğreticinin içeriği oluşturmada bu bakış açısına ulaşmasının, öğrencinin bağlamsal düşünme becerisi kazanarak, din bilgisi ve hayat bilgisini buluşturabilmesine katkı sağlayacağı düşünülmektedir. Makalede, dinden öğrenme modeli benimsenmiş ve yorumlayıcı yaklaşımla çalışılmıştır. Sonuç olarak bilginin hayatla buluşması yönünde emeği geçen öğreticileri, bilgiyi kendi yöntemsel çerçevesinde anlamaya ve insan varlığını ilgilendiren konuları öğretime müsait hale getirmenin çok yönlü ve bütüncül bir bakış açısıyla mümkün olabileceğini kavramaya ulaştıran nitelikli çalışmalara ihtiyaç olduğu söylenebilir.

In the late nineteenth and early twentieth century the name of Adam Smith was popularly associated with the sort of ‘laissez faire’ policy that is expounded with all the fervour of a religious faith. Smith, so the story ran, in his eagerness to combat the excessive mercantilist government intervention of his day, had resorted to supra-natural claims in his general onslaught against central control and planning by governments. Such intervention was ‘unnatural’ and conflicted with Deistic Design. Only through private actions (...) could mankind reach satisfying and ‘natural’ fulfillment. Action through private self-interest was twice blessed; it. blessed him who profited and his fellows who were ‘profited from’. True there was a kind of central planning that was of supreme importance; but it had a divine origin and it worked not through governments but through individual free trade. Private actions in fact were directed by an Invisible Hand which brought society into a grand and spontaneous Natural Harmony. (shrink)
