Retrace l'histoire du néant en Occident en étudiant ses étapes décisives et ses principales désignations.

The unconscious-thought effect occurs when distraction improves complex decision making. Recent studies suggest that this effect is more likely to occur with low- than high-demanding distraction tasks. We discuss implications of these findings for Newell & Shanks' (N&S's) claim that evidence is lacking for the intervention of unconscious processes in complex decision making.

The ‘right to the truth’ involves disclosing all the pertinent facts to a patient so that an informed decision can be made. However, this concept of a ‘right to the truth’ entails certain ambiguities, especially since it is difficult to apply the concept in medical practice based mainly on current evidence-based data that are probabilistic in nature. Furthermore, in some situations, the doctor is confronted with a moral dilemma, caught between the necessity to inform the patient (principle of autonomy) and (...) the desire to ensure the patient's well-being by minimising suffering (principle of beneficence). To comply with the principle of beneficence as well as the principle of non-maleficence ‘to do no harm’, the doctor may then feel obliged to turn to ‘therapeutic privilege’, using lies or deception to preserve the patient's hope, and psychological and moral integrity, as well as his self-image and dignity. There is no easy answer to such a moral dilemma. This article will propose a process that can fit into reflective practice, allowing the doctor to decide if the use of therapeutic privilege is justified when he is faced with these kinds of conflicting circumstances. We will present the conflict arising in practice in the context of the various theoretical orientations in ethics, and then we will suggest an approach for a ‘practice of truth’. Last, we will situate this reflective method in the broader clinical context of medical practice viewed as a dialogic process. (shrink)

This article is about the conception of truth and signification in Augustine's early philosophical writings. In the first, semantic-linguistic part, the gradual shift of Augustine's position towards the Academics is treated closely. It reveals that Augustine develops a notion of sign which, by integrating elements of Stoic epistemology, is suited to function as a transmitter of true knowledge through linguistic expressions. In the second part, both the ontological structure of signified things and Augustine's solution to the apparent tautologies of mathematical (...) truths are examined. Again his notion of sign turns out to be the keystone; this time, however, the natural in contrast to the conventional sign of linguistic expressions. In their complementarity, both parts show how Augustine intensely struggles with and overcomes the skepticism of the sensible world through his conception of sign and signification. (shrink)

It is only approximately one year before Sein und Zeit was published that Heidegger read Kant for the first time with attention and interest. Has this late reading had an influence on the treatise that Heidegger was writing? The thesis that we stand for is that Kant’s main influence shall be found in no passage of the treatise in particular, but mostly in the decision of adopting the form of a treatise.

On a souvent résumé la présence importante des avocats dans la vie politique française sous la III e République à travers l’expression de « République des avocats. » De manière plus complexe, il s’agit de montrer comment les avocats sont au cœur, dans les premières décennies de la République, de la construction d’un champ politique marquée par la codification des règles électorales et une certaine démocratisation du personnel politique. Dans les décennies qui suivent, on note une diversification des formes d’investissement (...) du barreau en politique, moins marqué par l’investissement dans le champ politique proprement dit que par l’engagement à travers la défense judiciaire de causes.

This article argues that many situations in social life can be analyzed by their requirement for the justification of action. It is in particular in situations of dispute that a need arises to explicate the grounds on which responsibility for errors is distributed and on which new agreement can be reached. Since a plurality of mutually incompatible modes of justification exists, disputes can be understood as disagreements either about whether the accepted rule of justification has not been violated or about (...) which mode of justification to apply at all. The article develops a grammar of such modes of justification, called orders of worth (grandeur), and argues that the human capacity for criticism becomes visible in the daily occurrence of disputes over criteria for justification. At the same time, it is underlined that not all social situations can be interpreted with the help of such a sense of justice, which resides on a notion of equivalence. Regimes of love, of violence or of familiarity are systematically distinct from regimes of justification. (shrink)

Au début des années 1930, la ville de Metz entreprend un projet de rénovation urbaine qui menace l’existence des maisons de tolérance. La gestion municipale de la prostitution en maisons closes semble bien souvent soumise aux pressions des notables alors que les rapports entre la société locale et la prostitution restent plus ambigus, comme en témoignent les lettres conservées dans les archives administratives qui font état de demandes de maintien de l’activité prostitutionnelle. Si les filles sont réprimées au quotidien, la (...) prostitution s’insère d’autant mieux dans la vie de la cité qu’il existe une communauté d’intérêts avérée avec les autres formes de commerce. Dès lors les véritables enjeux de la réforme locale de la prostitution sont mis en exergue : ils sont de nature économique. (shrink)

Recent events and popularized stereotypes call into question the ethics of salesperson behaviors. Although prior research demonstrates that salespeople’s emotional exhaustion can have negative consequences for several job outcomes, little is known about the factors that can mitigate such relationships—particularly the relationship between emotional exhaustion and ethical behavior. To remedy this knowledge gap, we draw from self-control theory to propose a novel theoretical framework and develop hypotheses. These hypotheses are tested on a unique dataset consisting of survey data collected from (...) 123 matched business-to-business salesperson–manager dyads. The findings reveal that emotional exhaustion is negatively associated with sales performance, emotional exhaustion is negatively associated with ethical behaviors, ethical behaviors are positively associated with sales performance, ethical behaviors mediate emotional exhaustion’s negative effect on sales performance, perceived supervisor support attenuates the negative association between emotional exhaustion and ethical behaviors, and contrary to expectations, grit strengthens the negative association between emotional exhaustion and ethical behaviors. As we show here, perceived supervisor support may attenuate the undesirable effects of emotional exhaustion on ethical behaviors and sales performance. The article’s broader contribution thus lies in its suggestion that managers pay special attention to these factors. Moreover, factors such as grit can have unexpected and undesirable influences; therefore, we draw attention to the importance of scrutinizing these interactions, even when the factors involved are almost universally touted as beneficial. Theoretical and practical implications of the research are discussed. (shrink)

EveryK-trivial set is computable from an incomplete Martin-Löf random set, i.e., a Martin-Löf random set that does not compute the halting problem.

We investigate the role of continuous reductions and continuous relativization in the context of higher randomness. We define a higher analogue of Turing reducibility and show that it interacts well with higher randomness, for example with respect to van Lambalgen’s theorem and the Miller–Yu/Levin theorem. We study lowness for continuous relativization of randomness, and show the equivalence of the higher analogues of the different characterizations of lowness for Martin-Löf randomness. We also characterize computing higher [Formula: see text]-trivial sets by higher (...) random sequences. We give a separation between higher notions of randomness, in particular between higher weak 2-randomness and [Formula: see text]-randomness. To do so we investigate classes of functions computable from Kleene’s [Formula: see text] based on strong forms of the higher limit lemma. (shrink)

Laurent Henninger intervenant sur les « révolutions militaires » (notion située au carrefour du débat historique lancé dans les années 1980 par Geoffrey Parker – en polémique avec Jeremy Black – et du débat stratégique américain dans les années 1990) souligne que les avancées dans l’art de la guerre ont été depuis cinq siècles une des composantes majeures de la barbarisation et du totalitarisme. La notion de « révolution militaire » est aujourd’hui contestée par ceux qui y voient un (...) outil interprétatif de trop longue durée et lui préfèrent l’idée de « mutations militaires » (selon laquelle l’accumulation de changements millimétriques sur la longue durée débouche sur des ruptures). Après avoir passé en revue la première révolution militaire – XVe-XVIIe siècles – fondée sur la mise à distance de la cavalerie grâce à l’infanterie nouvelle, à l’artillerie du champ de bataille, Henninger s’interroge sur le critère discriminant pour qualifier les nouvelles guerres de la Renaissance (l’hyperviolence n’en est pas un à ses yeux) et voit dans les armes à feu la vraie rupture car elles influent de façon radicale sur la peur et le courage des combattants et sont source d’une véritable « inhumanité » dans la mesure où leur feu est « imparable ». Il insiste sur l’émergence d’un nouveau type de courage guerrier non archaïque et plus « stoïcien » marqué par l’acceptation de la mort. Dans cette perspective, l’« inhumanisation » technique porterait en elle la possibilité de la barbarisation. L. Henninger développe ensuite cette thèse à partir de l’examen des guerres mécanisées de la période 1860-1950 en s’attardant sur la guerre de Sécession puis sur la Grande Guerre. Il relie aussi la question du totalitarisme à la réflexion sur les « bombardements stratégiques massifs » et les débuts de la dissuasion nucléaire (terme qui ne s’impose que vers 1960). Il conclut en insistant sur le fait que, selon lui, la brutalisation des conflits naît toujours d’un retard de la pensée de la guerre et sur le paradoxe d’une culture occidentale qui produit en même temps barbarie de la guerre et codes qui tentent de l’enrayer.

Nous montrons dans cet article comment les approches dynamiques en logique contemporaine ont retrouvé, quoique sous d ’ autres attendus, une configuration théorique qu ’ on peut attribuer à Aristote au moment de la rédaction des Topiques. Dans cette configuration, la logique et la rhétorique – ou au moins la dialectique – se complètent dans le cadre conceptuel homogène offert par la dialectique, entendue comme une certaine forme relativement codifiée de débat critique. L ’ idée principale est qu ’ aujourd (...) ’ hui, de même qu ’ alors, la dialectique est le cadre dans lequel il est possible de penser le rapport entre la logique et les formes générales de l ’ argumentation d ’ une part, et entre la logique et la théorie de la connaissance scientifique d ’ autre part.

The animal cell cytoskeleton consists of three interconnected filament systems: actin‐containing microfilaments (MFs), microtubules (MTs), and the lesser known intermediate filaments (IFs). All IF proteins share a common tripartite domain structure and the ability to assemble into 8–12 nm wide filaments. Electron microscopy data suggest that IFs are built according to a completely different plan from that of MFs and MTs. IFs are known to impart mechanical stability to cells and tissues but, until recently, the biomechanical properties of single IFs (...) were unknown. However, with the discovery of naturally occurring micrometer‐wide IF bundles and the development of new methodologies to mechanically probe single filaments, it is now possible to propose a more unified view of IF biomechanics. Unlike MFs and MTs, single IFs can now be described as flexible, extensible and tough, which has important implications for our understanding of cell and tissue mechanics. Furthermore, the molecular mechanisms at play when IFs are deformed point toward a pivotal role for them in mechanotransduction. BioEssays 29: 26–35, 2007. © 2006 Wiley Periodicals, Inc. (shrink)

A central object of study in the field of algorithmic randomness are notions of randomness for sequences, i.e., infinite sequences of zeros and ones. These notions are usually defined with respect to the uniform measure on the set of all sequences, but extend canonically to other computable probability measures. This way each notion of randomness induces an equivalence relation on the computable probability measures where two measures are equivalent if they have the same set of random sequences. In what follows, (...) we study the equivalence relations induced by Martin-Löf randomness, computable randomness, Schnorr randomness and Kurtz randomness, together with the relations of equivalence and consistency from probability theory. We show that all these relations coincide when restricted to the class of computable strongly positive generalized Bernoulli measures. For the case of arbitrary computable measures, we obtain a complete and somewhat surprising picture of the implications between these relations that hold in general. (shrink)

ArgumentThe Germans occupying Paris arrested Emile Borel and three other members of the Académie des Sciences in October 1941 and released them about five weeks later. Drawing on German and French archives and other sources, we argue that these events illustrate the complexity of the motivations and tactics of the occupiers and the occupied. While Borel and his colleagues were genuine members of the Resistance, and those who arrested them were full participants in a brutal occupation, both sides respected a (...) bargain, of no small importance to the Vichy regime, that allowed the university to pursue its work if its members avoided overt acts of opposition.

Cognitive forms vary considerably as a human being detaches herself from what is closest and most personal and moves to communicate — in the broad sense of taking part in a common matter — across increasing relational distances. The article proposes to deal with the variety of cognitive formats which cannot `commonize' cognition to an equal degree, relating them to a set of regimes of engagement with the world that are identified in terms of the dependency between the human agent (...) and her environment. The good that engagement aims to guarantee orients how reality is grasped and specifies the format of what constitutes relevant information. This analysis offers new insight into the composition of communities as well as persons who have to cope with the plurality of cognitive formats and engagements from the very familiar to the most public.

Nous comparons les notions d’usage et de signification chez Ludwig Wittgenstein et Martin Heidegger. Contrairement à Jocelyn Benoist, nous pensons que l’analogie entre Wittgenstein et Heidegger n’est pas superficielle. La métaphysique de Heidegger explicite certaines présuppositions implicites de la seconde philosophie de Wittgenstein. Le pragmatisme naturaliste de Wittgenstein peut être théorisé. Notamment la notion wittgensteinienne d’usage, ou de jeu de langage, peut être comprise comme une pratique à la fois naturelle et normative régie par des règles. -/- Wittgenstein’s notions of (...) use and meaning are compared with the corresponding Heidegger’s ones. Unlike Jocelyn Benoist, we suggest that the analogy between Wittgenstein and Heidegger is not superficial. Heidegger’s metaphysics makes explicit some of the implicit presuppositions of Wittgenstein’s philosophy. Wittgenstein’s naturalistic pragmatism can be theorized. In particular, Wittgenstein’s notion of use, or language game, can be understood as both natural and normative rule- governing practice. (shrink)

Associations between cardiorespiratory fitness and brain health in healthy older adults have been reported using a variety of cardiorespiratory fitness estimates. Using commonly used methods to determine CRF, we assessed the relationship between CRFe and executive function performance. Healthy older adults, underwent three CRF tests: a Maximal Graded Exercise Test performed on a cycle ergometer, the Rockport Fitness Walking Test, and a Non-Exercise Prediction Equation. Executive function was assessed by a computerized cognitive assessment using an N-Back task and a Stroop (...) task. Multiple hierarchical regression analyses were conducted to assess the relationship between different CRFe and executive function performance. Regardless of age and education, cardiorespiratory fitness estimated from the Maximal Graded Exercise Test and the Rockport Fitness Walking Test was significantly associated with the global switch cost. All CRFe were associated with the interference cost. No association was observed between CRFe and local switching costs or the updating costs. In the present study, not all subcomponents of executive function were related to CRFe. Interestingly, the executive functions that were associated with CRFe are those that are known to be the most affected by aging. (shrink)

Past research dedicated to the impact of hierarchy on the autonomic nervous system has focused mainly on dominance. The current study extends this investigation by assessing the effect of social prestige, operationalized through occupational status, and examines whether people react differently when interacting with individuals of high or low occupational status. Participants’ heart rate and electrodermal activity were recorded while they interacted with a confederate who was introduced either as a neurosurgeon or as a nurse aide. The results show that, (...) contrary to the participants’ skin conductance level, their heart rate was modulated by the confederate’s status. In the high-status condition, participants’ heart rate increased when the “neurosurgeon” approached them, reaching a higher level than when interacting with the person in the low-status condition. We discuss our results in terms of the threats or opportunities that prestige may elicit. (shrink)

Pascal a croise le jeu a plusieurs reprises. En reflechissant sur des parties de cartes (ou de des) interrompues, le mathematicien jette les bases de ce qui deviendra ulterieurement le calcul des probabilites. L'auteur des Pensees, qui concoit ses lecteurs sous les traits de libertins et joueurs notoires, leur presente une societe entierement soumise au hasard; il en sonde les lois comme des regles de jeu. L'objet de cette etude n'est pas d'etablir une thematique du jeu dans l'oeuvre de Pascal, (...) mais de proposer cette notion de jeu comme un modele, un prisme a travers lequel un certain nombre de realites incompatibles coexistent neanmoins. Le modele du jeu rend compte ainsi de quelques-uns des paradoxes les plus stimulants sur lesquels roulent les Pensees: comment le conservatisme politique de Pascal s'accompagne d'une mise en cause radicale des lois, comment le monde en proie au jeu est un monde a la fois fondamentalement desordonne et admirablement regle. Quant au Pari, qui fascine et embarrasse depuis plusieurs siecles, une etude attentive des notions mathematiques qui le sous-tendent permet d'eclairer quelques obscurites du texte, et de poser une fois encore, mais sur de nouvelle bases, la question de sa portee et de sa validite.
