L’encadrement aporétique est une méthode d’animation en Philosophie Pour Enfants et Adolescents basé sur la confrontation d’idées, et par là d’argumentations divergentes. Il s’agit d’inviter les jeunes à toucher aux limites de leur entendement en les amenant dans l’impasse générée par les mises en contradiction de leurs opinions, les mises en opposition de leurs explications, les mises en demeure de leurs certitudes. Ce qui est pensé est remis en question, du seul fait qu’une autre manière de le penser existe. La (...) cohabitation de ses variétés de pensées engendre la nécessité de parfaire la réflexion et d’approfondir le raisonnement. L’aporie se conçoit alors comme un moyen de contrainte privilégié permettant la progression de la pensée. Il s’agit ici, dans un premier temps, de présenter les fondements théoriques d’un tel encadrement philosophique basé sur l’aporie, et dans un second temps, d’exposer sa praticabilité. (shrink)

Professeur Finkelstein avait posée la question, pourquoi, bien que leurs réalisations scientifiques et leur scientifique approche soient similaires, Bernard était beaucoup plus connu dans son pays, France, et à son époque, que Bois-Reymond en Allemagne? Une question similaire a été posée au sujet du pourquoi Darwin est connu pour la théorie de l'évolution, tandis que Wallace a été remis en arrière-fond dans leur temps et dans l'histoire. Selon Finkelstein, la cause de la differences entre Bois-Reymond et Bernard, peut être trouvée (...) dans la culture et la place de la science dans l'œil public en France contre les memes choses en Allemagne. C'est-à-dire, la rhétorique de la science a été plus respectée en France qu'en Allemagne, ce que Finkelstein a soutenu avec persuasion et éloquence. (shrink)

Dr André Berge : médecin et psychanalyste, est directeur médical du Centre psycho-pédagogique Claude Bernard. Les données traditionnelles, toutes les valeurs, tous les principes sont discutés et sans cesse remis en cause. Et pourtant, personne ne saurait échapper à la nécessité d’adopter dans l’existence une ligne de conduite — c’est-à-dire une morale — sous peine de sombrer dans l’incohérence. Mais l’homme, s’il a besoin d’une morale, n’en est pas moins enclin à l’utiliser pour s’écraser lui-même et tend parfois à (...) transformer cet instrument en une arme qu’il lui arrive de retourner contre sa propre personne. C’est cela qu’il s’agit d’empêcher. Ce que veut établir cet ouvrage, ce sont les bases d’une morale psychologique tendant à remédier au désarroi des esprits et à contribuer à l’avènement d’un nouvel humanisme. (shrink)

This article explores a training need common to every stage of a teacher’s career : the need to be accompanied. It takes an integrative perspective on the process of the situated learning of teaching, throughout the career, from the pre-service practicums to the period of entrance in the profession then to the in-service training. Providing a reflexive accompaniment of the teachers’ practical experiences is here presented as a central factor for linking the training and the work environments. The first part (...) of the article exposes our conception of a reflexive accompaniment and justifies its importance for the evolution of the teaching practices. Then, we describe how we were convinced of that importance through our role as directors of two teacher training devices, one in Switzerland, one in Quebec. Finally, the third part of the article is devoted to the training of the persons that practice such an accompaniment. (shrink)

We investigate the nature of the sense of presence that usually accompanies perceptual experience. We show that the notion of a sense of presence can be interpreted in two ways, corresponding to the sense that we are acquainted with an object, and the sense that the object is real. In this essay, we focus on the sense of reality. Drawing on several case studies such as derealization disorder, Parkinson’s disease and virtual reality, we argue that the sense of reality is (...) two-way independent from the spatial and sensory contents of experience. We suggest that the sense of reality is an affective experience akin to a metacognitive feeling. Finally, we present a potentially important implication of our account for the current debate between Intentionalism and Naïve Realism. Since perception is “opaque” with respect to the reality of what is perceived, Intentionalism cannot refer to the sense of reality as what differentiates perception from sensory-like experiences such as imaginings. In contrast, Naïve Realism has an independent explanation of the specificity of perception. (shrink)

WHO II low grade glioma evolves inevitably to anaplastic transformation. Magnetic resonance imaging is a good non-invasive way to watch it, by hemodynamic and metabolic modifications, thanks to multinuclear spectroscopy 1H/31P. In this work we study a multi-scale minimal model of hemodynamics and metabolism applied to the study of gliomas. This mathematical analysis leads us to a fast-slow system. The control of the position of the stationary point brings to the concept of domain of viability. Starting from this system, the (...) equations bring to light the parameters that push glioma cells out of their domain of viability. Four fundamental factors are highlighted. The first two are cerebral blood flow and the rate of lactate transport through monocarboxylate transporters, which must be reduced in order to push glioma out of its domain of viability. Another factor is the intra arterial lactate, which must be increased. The last factor is pH, indeed a decrease of intra cellular pH could interfere with glioma growth. These reflections suggest that these four parameters could lead to new therapeutic strategies for the management of low grade gliomas. (shrink)

Husserl saw the Cartesian critique of scepticism as one of the eternal merits of Descartes’ philosophy. In doing so, he accepted the legitimacy of the very idea of a universal doubt, and sought to present as an alternative to it a renewed, specifically phenomenological concept of self-evidence, making it possible to obtain an unshakable foundation for the edifice of knowledge. This acceptance of the skeptical problem underlies his entire conceptual framework, both before and after the transcendental turn, and especially the (...) immanence/transcendence distinction, i.e., the very basis of intentionality. In taking as its starting point an analysis of perception, the article puts forth a certain number of phenomenological arguments in order to put into question the validity of the skeptical problem and, therefore, of the Husserlian conceptual framework; it defends, in the first place, a disjunctive conception of perception and, in the second place, a holism of experience.

I describe the general structure of most infinite regress arguments; introduce some basic vocabulary; present a working hypothesis of the nature and derivation of an infinite regress; apply this working hypothesis to various infinite regress arguments to explain why they fail to entail an infinite regress; describe a common mistake in attempting to derive certain infinite regresses; and examine how infinite regresses function as a premise.

Résumé L’écriture, la peinture et la relation à l’architecture sont les trois points d’entrée de ce rappel de l’œuvre de Claude Rutault, au travers d’une mise en parallèle avec celle de Rémy Zaugg. Sur le mode du témoignage, Xavier Douroux revient sur l’histoire du Consortium et de sa coopération avec Claude Rutault, notamment sur les expériences de peinture « en architecture » à la villa Savoye de Le Corbusier, à l’agence de Dominique Perrault, au pavillon de Mies Van (...) der Rohe, et à l’ Éclat de folie de Bernard Tschumi.

This paper discusses some of the ways in which circular definitions and circular explanations entail or fail to entail infinite regresses. And since not all infinite regresses are vicious, a few criteria of viciousness are examined in order to determine when the entailment of a regress refutes a circular definition or a circular explanation.

Taking the problem of perception and illusion as a leading clue, this article presents a new phenomenological approach to perception and the world: holism of experience. It challenges not only Husserl’s transcendentalism, but also what remains of it in Heidegger’s early thought, on the grounds that it is committed to the skeptical inference: Since we can always doubt any perception, we can always doubt perception as a whole. The rejection of such an implicit inference leads to a relational paradigm of (...) Being-in-the-World that differs from Heidegger’s on many points. (shrink)

ArgumentAfter having measured the velocity of the nervous impulse in the 1850s, Helmholtz began doing research on the temporal dimensions of visual perception. Experiments dealing with the velocity of propagation in nerves were carried out occasionally for some fifteen years until their final publication in 1871. Although the temporal dimension of perception seems to have interested Helmholtz less than problems of geometry and space, his experiments on the time of perception were technically rather subtle and seminal, especially compared with experiments (...) performed by his contemporaries, such as Sigmund Exner, William James, Rudolf Hermann Lotze, Ernst Mach, Wilhelm Volkmann, and Wilhelm Wundt. Helmholtz’s conception of the temporal aspects of perception reflects the continuity that holds between psychophysiological research and the Kantian philosophical background. (shrink)

La désignation de risques comme problèmes publics ainsi que la sélection et la hiérarchisation de ces risques s’expliquent souvent de trois grandes façons : soit comme le résultat d’arbitrages opérés par les autorités publiques ; soit comme le résultat de confrontations entre « société civile » et autorités publiques ; soit encore comme le résultat de la manière dont de multiples acteurs définissent et construisent les problèmes. Une des questions qui se posent est celle du statut de ces explications mobilisées (...) par des acteurs et des chercheurs. Correspondent-elles à des modes d’analyses ou bien sont-elles avant tout des discours intégrant les contraintes rhétoriques propres à tout problème public faisant l’objet de nombreuses appropriations, comme c’est le cas aujourd’hui avec les risques collectifs ?The designation of risks as public problems as well as the selection and the grading of these risks are often explained in three great ways : either like the result of arbitrations operated by the public authorities ; either like the result of confrontations between « civil society », and public authorities ; or still as the result of the way in which multiple actors define and build the problems. One of the questions which arise is that of the status of these explanations mobilized by actors and researchers. Do they correspond to modes of analyses or are they above all speeches integrating the rhetorical constraints which are specific to any public problem being the subject of many appropriations, as it is the case today with collective risks ?

Contemporary philosophy, from Kant through Bergson and Husserl to Heidegger, has assumed that time must be conceived as a fundamental determination of the subject: Time is not first in things but arises from actions, attitudes, or comportments through which a subject temporalizes mtime, expecting or remembering, anticipating the future or making a decision. Event and Time traces the genesis of this thesis through detailed, rigorous analyses of the philosophy of time in Plato, Aristotle, and Augustine, ultimately showing that, in the (...) development of metaphysics, the understanding of the temporal phenomenon as an inner-temporal phenomenon has made possible time's subjectivization. The book goes on to argue that time is in fact not thinkable according to metaphysical subjectivity. Instead, the guiding thread for the analysis of time must shift to the eventual hermeneutics of the human being, first developed in Event and World, and now deepened and completed in Event and Time. Romano's diptych makes a compelling, rigorous, and original philosophical contribution to the thinking of the event. (shrink)

In this introductory paper, I try to give an overview of the concept of normativity in its philosophical history and its contemporary interpretations and uses in different fields. From philosophy of logic and mathematics to philosophy of language and mind, and to philosophy of medicine and care, normativity is found as a key concept pointing at the possibility of scientific and technical progress and improvement of human life in the interaction between the individual and his environment.

L'idéal universaliste, qui a traversé les siècles jusqu'à aujourd'hui en surplombant les traditions intellectuelles tant chinoise qu'européenne, a façonné un certain nombre de nos représentations et imposé l'idée d'une antinomie entre ce qui relève de l'universel et ce qui renvoie à l'existence du particulier. Outre ce que, à bien y regarder, cette incompatibilité supposée peut avoir de paradoxal, divers épisodes chinois ou européens montrent que, au cours de sa très longue histoire, l'universalisme a aussi entretenu des relations équivoques avec des (...) créations historiques instituant des communautés particulières, telle la nation. Et ce sont ses rapports, tantôt connivents, tantôt antagoniques avec un ensemble de constructions mentales ou historiques particularisantes que l'auteure envisage en première partie. A partir du XVIIe siècle, les deux universalismes évoluent dans une certaine interaction, au gré des rencontres de leurs divers représentants ou de moments de proximité intellectuelle : c'est cette histoire de leurs relations, longue de plus de quatre siècles, que retrace la seconde partie. Le dialogue né de cette interaction, marqué par des méprises et incompréhensions, aura été quelque peu tortueux, mais néanmoins fructueux, dans la mesure où il aura favorisé une prise de conscience par chacun des deux universalismes... d'eux-mêmes.

Édition commentée des deux fragments de manuscrits littéraires grecs découverts dans la trésorerie du palais d'Aï-Khanoum, dans un contexte daté de 145 av. J.-C. Ces manuscrits avaient été rédigés dans des officines méditerranéennes et sont paléographiquement datables entre le milieu du IIIe et le début du IIe s. av. J.-C. Le premier texte, rédigé sur papyrus, est un dialogue philosophique platonicien ou aristotélicien relatif à la théorie platonicienne des Idées ; le second, rédigé sur parchemin en trimètres iambiques, relève peut-être (...) du genre théâtral. Leur présence à Aï Khanoum atteste l'existence d'une bibliothèque dans le palais de cette cité. (shrink)

Samotność i tajemnica. Prolegomena do fenomenologii ludzkiej więzi (tłum. Marek Drwięga).

Based on a psychobiographical approach, this study addresses magical thinking across the life span of Paulo Coelho. Paulo Coelho, who was born in Brazil in the 1940s, has become one of the most sold and famous contemporary authors in the world. In his life, as well as in his books, which are mainly autobiographical accounts, magic and magical thinking, spirituality, meaningfulness, and the living of one’s dream, are key themes. The aim of this study was to explore magic and magical (...) thinking in Paulo Coelho’s life and creative works. The study uses a psychobiographical single case study approach within the methodological frame of Husserl’s phenomenology. The author, Paulo Coelho, was chosen as the subject of research. Documents providing both first person and third person perspectives were subjected to content analysis. The findings show that magical thinking played an important role in Coelho’s creative works and in his life, in the form, for example, of ascriptions of magic to key situations in his life, the performance of daily rituals, mystic interpretations of life events, and his deep religious faith. Magical thinking is usually regarded as indicative of pathological and inappropriate cognitive and psychological behaviour, especially when found in adults in a westernised culture. However, the analysis of Coelho’s life and works shows that magical thinking can be utilised creatively and be integrated into one’s life to enable personal development and growth while simultaneously providing fertile ground for creative production. In Paulo Coelho’s case, the intertwining of religion and magical thinking provided deep meaning that guided his personal development. (shrink)

This article focuses on systems psychodynamics and particularly on the CIBART-model which explores conflict, identity, boundary, authority, role and task and how these phenomena work out on an unconscious level. Therefore, this article presents empirical findings on CIBART in a German multinational engineering organization operating in South Africa. For this study, 16 managers where interviewed on their transformation toward Industry 4.0 with special interest in the interconnection how CIBART aspects play out in the South African context. Findings show that all (...) of the CIBART-phenomena are important during the transformation to more advanced technological levels and restructuring processes. Conclusions are drawn and recommendations are given how to deal with systems-psychodynamic influences within the organization. (shrink)

Résumé À partir de données expérimentales issues d’un jeu de la confiance répété, nous estimons des modèles structurels de formation des croyances permettant de distinguer les modes d’apprentissage des deux joueurs. Nous trouvons que les deux joueurs ne peuvent être décrits par le même mode d’apprentissage. Des simulations sur longue période montrent ensuite que l’interaction de ces deux types d’agents peut conduire à des issues contrastées.

The article looks at the varying forms taken by parenthood in different societies, past and present. It examines how it belatedly came to be defined by Lewis Morgan, in the context of our modern societies, in terms of an aristocratic and genetic conception, thus establishing a model which Lévi-Strauss unintentionally took to an aporia. Against such a schematic conceptualisation of parenthood, the article posits the material and sentimental links which grow from the responsibilities assumed for the material and educational needs (...) of minors by « parents » devoid of any genetic link to those who are dependent on their care.

The cheerleader effect describes the phenomenon whereby faces are perceived as being more attractive when flanked by other faces than when they are perceived in isolation. At least four theories predict the cheerleader effect. Two visual memory processes could cause a cheerleader effect. First, visual information will sometimes be averaged in the visual memory: the averaging of faces could increase the perceived attractiveness of all the faces flanked by other faces. Second, information will often be combined into a higher-order concept. (...) This hierarchical encoding suggests that information processing causes faces to appear more attractive when flanked by highly attractive faces. Two further explanations posit that comparison processes cause the cheerleader effect. While contrast effects predict that a difference between the target face and the flanking faces causes the cheerleader effect due to comparison processes, a change in the evaluation mode, which alters the standard of comparison between joint and separate evaluation of faces, could be sufficient for producing a cheerleader effect. This leads to the prediction that even when there is no contrast between the attractiveness of the target face and the flanking faces, a cheerleader effect could occur. The results of one experiment support this prediction. The findings of this study have practical implications, such as for individuals who post selfies on social media. An individual’s face will appear more attractive in a selfie taken with people of low attractiveness than in a selfie without other people, even when all the faces have equally low levels of attractiveness.

I argue that there are at least two kinds of tacit premises; describe a certain type of counterexample against the validity of arguments, and then use it to identify one kind of tacit premise. I distinguish two classes of tacit premises on the grounds that they are discovered or constructed differently, they have different roles in an argument or causal explanation, and have different logical relations to each other.

Showing that the premises of an argument are not sufficient for (viz., do not entail) a conclusion a conclusion involves citing a counterexample that would show the premises of the argument to be true and the conclusion false. This paper distinguishes counterexamples by analogy (an argument with the same form as argument against which it is advanced but where it is clearly the case that the premises are true and the conclusion is false), counterexamples by possible conjunction (a conjunction of (...) the premises and the negation of the conclusion), and counter-arguments (arguments directed against the truth of the conclusion). After detailing the logical differences between these concepts, the paper describes the pedagogical significance of this distinction and provides an assortment of test exercises for students.

In many species of reptiles, sex is determined at fertilization by zygotic sex chromosome composition. In other species, including all crocodilians, most turtles and some lizards, sex is determined by temperature during the earlier stages of gonadal differentiation. The effects of exogenous estrogens, antiestrogens and aromatase inhibitors at different temperatures have unambiguously demonstrated the involvement of estrogens in sexual differentiation of the gonads. Aromatase is the enzyme that converts androgens to estrogens. Gonadal aromatase activity is well correlated with gonadal structure. (...) It increases exponentially in differentiating ovaries, whereas it remains low in differentiating testes. Moreover, there is a high correlation between the thermosensitive periods for both ovary differentiation and increase in aromatase activity. We suggest that a thermosensitive factor intervenes, directly or indirectly, in the transcriptional regulation of the aromatase gene in reptiles with temperature‐dependent sex determination. (shrink)
