Van Heijenoort's main contribution to history and philosophy of modern logic was his distinction between two basic views of logic, first, the absolutist, or universalist, view of the founding fathers, Frege, Peano, and Russell, which dominated the first, classical period of history of modern logic, and, second, the relativist, or model-theoretic, view, inherited from Boole, Schröder, and Löwenheim, which has dominated the second, contemporary period of that history. In my paper, I present the man Jean van Heijenoort (Sect. 1); then (...) I describe his way of arguing for the second view (Sect. 2); and finally I come down in favor of the first view (Sect. 3). There, I specify the version of universalism for which I am prepared to argue (Sect. 3, introduction). Choosing ZFC to play the part of universal, logical (in a nowadays forgotten sense) system, I show, through an example, how the usual model theory can be naturally given its proper place, from the universalist point of view, in the logical framework of ZFC; I outline another, not rival but complementary, semantics for admissible extensions of ZFC in the very same logical framework; I propose a way to get universalism out of the predicaments in which universalists themselves believed it to be (Sect. 3.1). Thus, if universalists of the classical period did not, in fact, construct these semantics, it was not that their universalism forbade them, in principle, to do so. The historical defeat of universalism was not technical in character. Neither was it philosophical. Indeed, it was hardly more than the victory of technicism over the very possibility of a philosophical dispute (Sect. 3.2). (shrink)

In standard quantum mechanics, a state vector \ may belong to infinitely many different orthogonal bases, as soon as the dimension N of the Hilbert space is at least three. On the other hand, a complete physical observable A is associated with a N-dimensional orthogonal basis of eigenvectors. In an idealized case, measuring A again and again will give repeatedly the same result, with the same eigenvalue. Let us call this repeatable result a modality \, and the corresponding eigenstate \. (...) A question is then: does \ give a complete description of \? The answer is obviously no, since \ does not specify the full observable A that allowed us to obtain \; hence the physical description given by \ is incomplete, as claimed by Einstein, Podolsky and Rosen in their famous article in 1935. Here we want to spell out this provocative statement, and in particular to answer the questions: if \ is an incomplete description of \, what does it describe? is it possible to obtain a complete description, maybe algebraic? Our conclusion is that the incompleteness of standard QM is due to its attempt to describe systems without contexts, whereas both are always required, even if they can be separated outside the measurement periods.

We show how to encode context-free string grammars, linear context-free tree grammars, and linear context-free rewriting systems as Abstract Categorial Grammars. These three encodings share the same constructs, the only difference being the interpretation of the composition of the production rules. It is interpreted as a first-order operation in the case of context-free string grammars, as a second-order operation in the case of linear context-free tree grammars, and as a third-order operation in the case of linear context-free rewriting systems. This (...) suggest the possibility of defining an Abstract Categorial Hierarchy. (shrink)

Quelques années avant sa mort, Sartre soutient que, même s’il lui est arrivé d’écrire sur de tels sujets, il ignore aussi bien l’angoisse que le désespoir. Avec la sincérité – semble-t-il – d’un homme délivré du qu’en-dira-t-on, l’auteur de L’Être et le néant déclare : « j’ai parlé de désespoir, mais c’est de la blague, j’en ai parlé parce qu’on en parlait, parce que c’était la mode : on lisait Kierkegaard », et il ajoute à propos de l’angoisse : « (...) je n’ai jamais eu d’angoisse. Ce sont des no... (shrink)

Based on the analysis of narrations in Free Indirect Discourse and the Historical Present, we argue that the grammatical notion of context of speech should be ramified into a Context of Thought and a Context of Utterance. Tense and person depend on the Context of Utterance, while all other indexicals are evaluated with respect to the Context of Thought. Free Indirect Discourse and the Historical Present are analyzed as special combinatorial possibilities that arise when the two contexts are distinct, and (...) exactly one of them is presented as identical to the physical point at which the sentence is articulated.

In this paper, we show that the implication fragment of classical propositional logic is finitary for unification with parameters.

This paper develops an account of the normative basis of priority setting in health care as combining the values which a given society holds for the common good of its members, with the universal provided by a principle of common humanity. We discuss national differences in health basket in Europe and argue that health care decision-making in complex social and moral frameworks is best thought of as anchored in such a principle by drawing on the philosophy of need. We show (...) that health care needs are ethically ‘thick’ needs whose psychological and social construction can best be understood in terms of David Wiggins’s notion of vital need: a person’s need is vital when failure to meet it leads to their harm and suffering. The moral dimension of priority setting which operates across different societies’ health care systems is located in the demands both of and on any society to avoid harm to its members. (shrink)

In the tradition of quantified modal logic, it was assumed that significantly different linguistic systems underlie reference to individuals, to times and to ‘possible worlds’. Various results from recent research in formal semantics suggest that this is not so, and that there is in fact apervasive symmetrybetween the linguistic means with which we refer to these three domains. Reference to individuals, times and worlds is uniformly effected through generalized quantifiers, definite descriptions, and pronouns, and in each domain grammatical features situate (...) the reference of terms as near, far or ‘further’ from the actual or from a reported speech act. We outline various directions in which a program ofontological symmetrycould be developed, and we offer in theAppendixa symmetric fragment developed in a logic that can be seen as a compromise between an extensional and an intensional system.

Several disputes about the nature of experience operate under the assumption that experiences have parts, including temporal parts. There's the widely held view, when it comes to temporal experiences, that we should follow James' exhortation that such experiences aren't mere successions of their temporal parts, but something more. And there's the question of whether it is the parts of experiences which determine whole experiences and the properties they have, or whether the determination goes instead from the whole to the parts, (...) as holists have it. But what are parts, or temporal parts, of experiences exactly—what does it mean to say that an experience is “part” of another? Are the participants in those disputes talking about the same thing—is there a univocal notion of “experiential part” available? Are there different kinds of experiential parts? And if there are, is there a systematic way of carving them out? More importantly, how should we conceive of the temporal parts of experiences, and how can we establish that experiences really do have temporal parts, against those who reject the notion? (shrink)

La question qu’on nomme aujourd’hui des « genres naturels » en métaphysique porte sur les « jointures » du monde : quelles classes de choses constituent le monde et existent réellement? Si nominalistes et réalistes s’opposent depuis longtemps sur la possibilité même de répondre à cette question, les sciences modernes proposent des découpages en genres naturels qui contrastent souvent avec l’image naturelle du monde. Cet article se concentre sur les genres naturels en biologie. Après avoir présenté le principe de réponse (...) offert par la biologie évolutive, à savoir la systématique cladistique, j’expose le paradoxe du poisson, puisque « poisson » n’y est pas un nom de classe objectif, et semble donc aussi peu réel que « légume ». Je montre ensuite comment ce paradoxe est abordé différemment par des conceptions réalistes ou pragmatistes des genres naturels, et, en distinguant plusieurs sortes de pragmatismes en fonction des pratiques sociales auxquelles ils réfèrent la vérité des énoncés, je défendrai un pragmatisme modéré quant aux genres naturels en biologie.

The main task of the article is to propose a critical analyses of the thesis of François Flahault that homo oeconomicus – an abstract subject of the cleaved Western consciousness – is responsible of economism and its mischiefs. The author shows the positive aspects of Flahault's interpretation, but also his simplifications and errors, by traversing the historical backgrounds of the concept of homo oeconomicus leading to the sophisms of the new economic doxa and its erroneous values.

Cet article propose de confronter le thème kojévien de « la disparition de l’homme à la fin de l’histoire » et le thème foucaldien de la « mort de l’homme ». Cette confrontation permet non seulement de faire apparaître le déplacement qui s’opère de Kojève à Foucault en ce qui concerne le cadre théorique de leur réflexion sur l’homme, mais aussi de souligner les effets contrastés de la lecture kojévienne de Hegel sur Sartre et sur Bataille.This paper aims at confronting (...) the Kojevian theme of « the Disappearance of Man at the end of History » and the Foucaldian theme of the « Death of Man ». This comparison allows one the displacement from Kojève to Foucault as regards the theoretical frame of their thoughts about Man, and also to emphasize the contrasted effects of the Hegelian reading of Kojève on Sartre and on Bataille.

The paper presents a new logic for reasoning about the formation of beliefs through perception or through inference in non-omniscient resource-bounded agents. The logic distinguishes the concept of explicit belief from the concept of background knowledge. This distinction is reflected in its formal semantics and axiomatics: we use a non-standard semantics putting together a neighborhood semantics for explicit beliefs and relational semantics for background knowledge, and we have specific axioms in the logic highlighting the relationship between the two concepts. Mental (...) operations of perceptive type and inferential type, having effects on epistemic states of agents, are primitives in the object language of the logic. At the semantic level, they are modelled as special kinds of model-update operations, in the style of dynamic epistemic logic. Results about axiomatization, decidability and complexity for the logic are given in the paper. (shrink)

We argue that the pictorial nature of certain constructions in signs and in gestures explains surprising properties of their syntax. In several sign languages, the standard word order (e.g. SVO) gets turned into SOV (with preverbal arguments) when the predicate is a classifier, a distinguished construction with highly iconic properties (e.g. Pavlič, 2016). In silent gestures, participants also prefer an SOV order in extensional constructions, irrespective of the word order of the language they speak (Goldin-Meadow et al., 2008). But in (...) silent gestures and in Brazilian Sign Language (Libras), intensional constructions can override these SOV preferences, yielding SVO instead (Schouwstra & de Swart, 2014; Napoli et al., 2017). This distinction was argued to be due to iconicity: arguments are expressed before the verb if they correspond to entities that are present before the action, otherwise they follow the verb. While agreeing with this intuition, we propose that the extensional/intensional distinction is neither empirically nor theoretically appropriate. In new data from American Sign Language, we replicate the distinction among extensional classifier predicates: for _x ate up the ball_, the ball is typically seen before the eating and a preposed object is preferred; but for _x spit out the ball_, the ball is typically seen after the spitting and a postposed object is preferred, although both _eat up_ and _spit out_ are used extensionally. We extend this finding to data involving pro-speech (= speech-replacing) gestures embedded in French sentences. We argue for a Visibility Generalization according to which arguments appear before the verb if their denotations are typically visible before the action, and we develop a new formal account within a pictorial semantics for visual animations (inspired by Greenberg and Abusch). It derives the observed word order preferences, it explains how the semantics of classifier predicates combines iconic and conventional properties, and it makes a more general point: sign language semantics combines logical semantics with pictorial semantics.

Animal research suggests that central serotonergic neurons are involved in behavioral suppression, particularly anxiety-related inhibition. The hypothesis linking decreased serotonin transmission to reduced anxiety as the mechanism in the anxiolytic activity of benzodiazepines conflicts with most clinical observations. Serotonin antagonists show no marked capacity to alleviate anxiety. On the other hand, clinical signs of reduced serotonergic transmission (low 5-HIAA levels in the cerebrospinal fluid) are frequently associated with aggressiveness, suicide attempts, and increased anxiety. The target article attempts to reconcile such (...) human and animal findings by investigating whether anxiety reduction or increased impulsivity is more Likely to account for animal behavioral changes associated with decreased serotonergic transmission. The effects of manipulating central serotonin in experimental anxiety paradigms in animals (punishment, extinction, novelty) are reviewed and compared with the effects of antianxiety drugs. Anxiety seems neither necessary nor sufficient to induce control by serotonergic neurons on behavior. Further evidence suggests that behavioral effects of anxiolytics thought to be mediated by decreases in anxiety are not caused by the ability of these drugs to reduce serotonin transmission. Blockade of serotonin transmission, especially at the level of the substantia nigra, results in a shift of behavior toward facilitation of responding. This behavioral shift is particularly marked when there is competition between acting and restraining response tendencies and when obstacles prevent the immediate attainment of an anticipated reward. It is proposed that serotonergic neurons are involved not only in behavioral arousal but also in enabling the organism to arrange or tolerate delay before acting. Decreases in serotonin transmission seem to be associated with the increased performance of behaviors that are usually suppressed, though not necessarily because of the alleviation of anxiety, which might contribute to the suppression.

The challenges posed by chronic illness have pointed out to epidemiologists the multifactorial complex nature of disease causality. This notion has been referred to as a web of causality. This web extends theoretically beyond risk markers. It includes determinants of emergence/non-emergence of disease. This web of determinants is a form of complex system. Due to its complexity, the determinants within such system are not linked to each others in a linear, predictable manner only. Predictability is possible only on a short-term (...) basis, and unpredictability sets in over the long run. Understanding such a system of determinants calls for articulation and testing of complex models which synthesize our knowledge of multiple determinants at many scales, both biological and otherwise. Given the complexity of this web and existing knowledge about the nonlinearity of such systems, the following question is posed: Can the challenge of studying causality be adequately addressed if emphasis continues to be placed on using tools and methods that are geared towards looking at such system from a linear paradigm? Or is it time to add to the epidemiologic research agenda the notion of nonlinearity and its relevant form of analytical approaches that are being tested in other disciplines? Furthermore, the question posed here applies as well to the study of determinants of health. Addressing determinants of heath adds further complexity to our task. (shrink)

This is a study that investigated the extent of use of the three principles of ethics – utility, morality, and justice – in managerial ethical decision making, in addition to the personal attitude towards them. It involved undergraduate and graduate business students (total N=163) from the Olayan School of Business in the American University of Beirut, Lebanon. Two kinds of measurements were done: self assessment, and testing with the Saschkin’ s Managerial Value Profile (1997). It showed that morality was the (...) overriding ethical principle used, especially in the graduate group (professionals). Business students still believed in the justice system despite the weakness of the country’s law. Utility was the least used, although males were found to be more utilitarian than females. Finally there was no relation between personal attitudes toward the three ethical principles, and the intentional behavior when faced with ethical dilemmas. The findings were discussed and recommendations were given. (shrink)

ABSTRACT Taking the example of the French Résistance and by summoning up the twin rhetorical concepts of kinesis and energeia, this article establishes the long reach of a national liberation trajectory, of which the Résistance was a key moment in its attempt to free the country and to move ahead with the project and promise of an ideal republic.

Que fait la justice numérique à la théorie et à la pratique du droit? Qu’induit-elle pour la vocation de justice de l’institution judiciaire? Comment en bouleverse-t-elle les différents métiers? Jean Lassègue et Antoine Garapon mènent une enquête approfondie pour différencier soigneusement les deux formes symboliques du numérique et du droit. Ils s’efforcent ainsi de ménager ainsi une troisième voie qui sache éviter tout autant la fascination dogmatique des juristes pour la tendance « loi et mathématique » (la tentation de fonder (...) la rationalité juridique sur la formalisation) que l’ambition légale démesurée de l’informatique contemporaine (la prétention actuelle des algorithmes à empiéter sur tous les domaines, y compris le droit). Il doit être possible de résister à l’automatisation pour inventer une justice, certes, assistée par ordinateur, mais sachant rester humaine. Reste à savoir comment. (shrink)

Jusqu'au IXe siècle, en Orient où l'Empire romain perdure comme en Occident où il n'existe plus, « l'Église » se pense et se vit sur le mode synodal, avec les nuances qu'apporte, ici, l'idéologie eusébienne, donnant le primat au « palais royal » sur le « siège apostolique », et, là, l'augustinienne, qui soutient l'inverse. Deux siècles plus tard, alors que l'Empire byzantin a cessé de prétendre à l'universalité romaine, la chrétienté latine occidentale ne rêve que de renovatio romani imperii, (...) à son bénéfice. Entre ces deux moments, il y a l'éphémère aventure de Gerbert d'Aurillac qui, après avoir défendu à Reims la cause des évêques contre le pape, devint, par la grâce d'Otton III, le pape de l'An Mil, Sylvestre II : c'était le nom que portait le pontife du temps de Constantin, auquel le nouvel empereur ne cesse de se référer, en souhaitant un empire moins germanique qu'universel. Ce dut être une grande joie, pour le pape, d'entendre Otton dire en 1001 : « Nous proclamons Rome capitale du monde et nous reconnaissons l'Église romaine comme mère de toutes les Églises. » Désormais, la communion n'est plus réglée par la lex communis ecclesiae catholicae, mais par 1'unius arbitrium et Sylvestre II parlera en « père universel », conscient d'exercer seul le ministère de Pierre. C'est dans ces fortes convictions que l'Église romaine affrontera la crise de la chrétienté des XIIIe-XIVe siècles. Up until the ninth century, when the Roman Empire continued in the East but ceased to exist in the West, « the Church » thought and lived in the synodal mode. The slight difference was that Eusebien ideology prevailed in the East, which gave primacy to the « royal palace » over the « apostolic seat », while Augustinien ideology held the contrary in the West. Two centuries later, when the Byzantine Empire ceased to pretend to Roman universality, western Latin Christianity dreamed only of the renewal of the Roman Empire, to its own advantage. Between these two moments, there was the ephemeral adventure of Gerbert of Aurillac who, after having defended the cause of the bishops against the pope at Reims, became pope Sylvester II in the year 1000, thanks to Otto III. Sylvester was the name of the pontiff at the time of Constantine, to whom the new emperor didn’t cease to compare himself in wishing an empire less Germanic than universal. It must have been a great joy for the pope to hear Otto say in 1001 : « We proclaim Rome the capital of the world and we recognize the Roman Church as mother of all the Churches. » In the future, communion was no longer regulated by the Catholic Church's common law, but by the unius arbitrium, and Sylvester II will speak as « universal father », conscious of exercising alone the ministry of Peter. It is with these strong convictions that the Roman Church would face the crisis of Christianity in the XIII and XIV centuries. (shrink)

If the new and rapidly expanding discipline of neuroethics is to have a signii cant impact on patient care, the neuroscience clinicians must become familiar with the discipline, and be competent and comfortable in applying its cognitive base and principles to clinical decisionmaking. Familiarity with and practical experience in the application of basic biomedical knowledge and principles to clinical decision- making in the neurosciences becomes the essential foundation on which to begin to integrate neuroethics into medical education. The place where (...) the building of this foundation and the initial exposure to neuroethics must begin is in the residency program. This article describes the approach developed in the neurology residency education program at the University of Calgary to move toward achieving this goal. The key elements for the development and successful implementation of the program are outlined and a brief overview of the topics covered in the sessions is described. (shrink)

Des premiers rites baptismaux à la confession moderne, les références au christianisme sont constantes dans l'œuvre de Michel Foucault. Cette constance s'inscrit dans un questionnement philosophique plus large sur notre actualité : comprendre le rapport que nous avons aujourd'hui à nous-mêmes demande de s'interroger sur les actes de vérité que l'Occident a instaurés depuis les premiers siècles chrétiens. Que faut-il dire et manifester de soi pour être transformé dans son être, pardonné, sauvé, jugé ou guéri)?
