Learning a novel environment involves integrating first-person perceptual and motoric experiences with developing knowledge about the overall structure of the surroundings. The present experiments provide insights into the parallel development of these egocentric and allocentric memories by intentionally conflicting body- and world-centered frames of reference during learning, and measuring outcomes via online and offline measures. Results of two experiments demonstrate faster learning and increased memory flexibility following route perspective reading (Experiment 1) and virtual navigation (Experiment 2) when participants begin exploring (...) the environment on a northward (vs. any other direction) allocentric heading. We suggest that learning advantages due to aligning body-centered (left/right/forward/back) with world-centered (NSEW) reference frames are indicative of three features of spatial memory development and representation. First, memories for egocentric and allocentric information develop in parallel during novel environment learning. Second, cognitive maps have a preferred orientation relative to world-centered coordinates. Finally, this preferred orientation corresponds to traditional orientation of physical maps (i.e., north is upward), suggesting strong associations between daily perceptual and motor experiences and the manner in which we preferentially represent spatial knowledge.

Description courte (Électre, 2019) : Une étude d'un des principaux axes de réflexion du philosophe des sciences et de la nature Raymond Ruyer (1902-1987). À la lumière des découvertes de l'embryogenèse et en s'appuyant par ailleurs sur la théorie de l'information, il proposa une interprétation des concepts unificateurs de la cybernétique mécaniste. -/- Short Descriptor (Electre 2019): A study of one of the main axes of reflection of the French philosopher of science and of nature Raymond Ruyer (1902-1987). Relying on (...) the discoveries about embryogenesis, and also with the use of information theory, Ruyer proposed an interpretation of the main unifying concepts of mechanistic cybernetics. -/- Cet ouvrage propose une étude fouillée d'un des principaux axes de réflexion du philosophe des sciences et de la nature français Raymond Ruyer (1902–1987) : la cybernétique. Après avoir proposé une philosophie structuraliste, Ruyer la modifia à la lumière des découvertes de l'embryogenèse, puis il proposa une interprétation des concepts unificateurs de la cybernétique mécaniste. Réfléchissant sur cette dernière et sur la théorie de l'information, en particulier sur l'origine de l'information, il défendit que cette cybernétique n'était qu'une lecture inversée de la vraie cybernétique, qui nous donnerait de lire dans l'expérience même les traces du pouvoir morphogénétique, appréhendé comme un champ axiologique. Dans un texte résumant son propre parcours, Ruyer affirma finalement que la critique de la théorie de l'information « peut donner […] l'espoir d'aboutir à quelque chose comme une nouvelle théologie. » Les idées directrices de Ruyer sont tout particulièrement contextualisées ici à partir de la question du développement des formes en biologie, et de celles de la génétique, de la genèse stochastique de l'ordre, et de l'identification mentale ou physique de l'information. Il se termine en départageant ce qui est théologique et axiologique dans ce projet de métaphysique qui, bien que resté inachevé, n'en représente pas moins le plus impressionnant conçu en France au siècle dernier. – This book offers an in-depth study of one of the main axes in the reflection of French philosopher of science and nature Raymond Ruyer. In a text summarising his own development, Ruyer stated about the philosophical critique of information theory that it "is what can give the most long-lasting hope of getting to something like a new theology." After propounding a structuralist philosophy, and distinguishing between form and structure, to then modify it in the light of discoveries in embryogenesis, Ruyer offered a re-evaluation of the unifying concepts of mechanistic cybernetics. Thinking about it and about information theory, he defended the idea that this cybernetics was in reality an inverted reading of the real one, which would allow us to read in experience itself traces of the morphogenetic power, apprehended as the axiological field. On some transversal points, the development of forms in biology and genetics, the stochastic genesis of order, the identification of information with either psychological and mental, or physical reality, behaviour, and the access to meaning, this work exposes the main ideas of Ruyer while situating them in the context of the breadth of others' contributions. It ends by determining what is theological and axiological in this project for a metaphysics which, although unfinished, is nevertheless the most impressive effort done in France in the last century. – Available on i6doc dot com (ISBN 978-2-930517-56-8 ; pdf 978-2-930517-57-5).

I present first the challenge for epistemology when it faces the dilemma between rationalism and empiricism, followed by a presentation of the ideas introduced by Ruyer in order to ask if they can be articulated to the "third way" in epistemology. I explore the consequences of Ruyer's inversion of our understanding of space which can be looked upon as psychic. I consider Ruyer's refusal to locate in pure immanence the scheme of eupraxic resolution of successful aggregates–as living forms–in our experience. (...) I then highlight the major principles of Gaston Bachelard's and Michel Serres's respective epistemologies, and in a lesser measure those of Bergon and Deleuze as well, in order to underscore Ruyer's refusal to limit philosophy to what science allows one to say, but also in order to finally situate the verticalism of his position.

Teilhard de Chardin is a fascinating character! Born in 1881 and deceased in 1955, he remains strikingly contemporary. In response to a world shattered by the atrocities of World War I, he progressively elaborates the vision of a world entirely unified through a Center beyond itself. This perception is inserted at the heart of an intellectual endeavor wherein faith and scientific pursuit call onto each other, intertwined in a dialogue of a rare fruitfulness. Books such as The Phenomenon of Man, (...) The Divine Milieu, the Writings in time of War, or The Heart of the Matter witness to his underlying insight: "true" mysticism and the thrust of science which spiritualizes the earth coincide and are in fact one. Besides introducing to the life and thought of Teilhard de Chardin, this book is an anthology of his greatest texts where he discloses for us his mystical insights. (shrink)

This paper provides a method for characterizing space events using the framework of conceptual spaces. We focus specifically on estimating and ranking the likelihood of collisions between space objects. The objective is to design an approach for anticipatory decision support for space operators who can take preventive actions on the basis of assessments of relative risk. To make this possible our approach draws on the fusion of both hard and soft data within a single decision support framework. Contextual data is (...) also taken into account, for example data about space weather effects, by drawing on the Space Domain Ontologies, a large system of ontologies designed to support all aspects of space situational awareness. The framework is coupled with a mathematical programming scheme that frames a mathematically optimal approach for decision support, providing a quantitative basis for ranking potential for collision across multiple satellite pairs. The goal is to provide the broadest possible information foundation for critical assessments of collision likelihood. (shrink)

Radical democratic thinking is becoming intrigued by the material situatedness of its political agents and by the role of nonhuman participants in political interaction. At stake here is the displacement of narrow anthropocentrism that currently guides democratic theory and practice, and its repositioning into what we call ‘the nonhuman condition’. This Critical Exchange explores the nonhuman condition. It asks: What are the implications of decentering the human subject via a new materialist reading of radical democracy? Does this reading dilute political (...) agency? Or should this be seen, on the contrary, as an invitation for new voices and demands to enter into democratic assemblages? How might engagement with the more-than-human disrupt or extend theories of radical democracy? Hans Asenbaum and Amanda Machin discuss the human democratic subject both through radical democratic and new materialist lenses. They suggest that a new materialist decentred subject does not lose agency but further gains political responsibility in radical democracy. Jean-Paul Gagnon highlights the possibility of becoming through loss. In losing our anthropocentric arrogance—our understanding of being other and better than animal—we become more connected and discover our place in human-nonhuman assemblages. Melissa Orlie agrees that something can be gained through renouncing dominant human fantasies and presents a ‘radical democratic naturalism’. By renouncing land violence and acknowledging nature’s subjectivity, we can further nonexploitative radical democratic politics. This is where the notion of ‘tidalectic’ processes introduced by James L. Smith is helpful. Focusing on water and the Indigenous knowledges around rivers, he considers how democracy and community can be reimagined as plural, cyclical and attentive to the nonhuman with which the human is inevitably entangled. Diana Leong offers a different approach. Considering the nonhuman from the perspective of Black Studies demands an awareness to how blackness has long been constituted as non- or partially human.

Knowledge is still an enigma, with its ability to inductively bring out a pattern without restricting itself to an empirical count of situations experienced. Instead of seeing the concept as a weakened object representing an external reality, it is suggested to view knowledge as the bridging of a distance with an ability for the knower to stay connected with outward reality. Attempts at defining an external and quantitative criterion of truth are questioned, as many human performances are not likely to (...) be solved or even properly grasped by the project of artificial intelligence. The positive side of the cognitive constructivist project is finally assessed and it is argued that one of its unexpected results could be to reinsert the human knowing power in the sub-human realm.

Le présent essai examine d'abord les notions newtoniennes d'espace et de temps absolus en elles-mêmes et dans leurs relations réciproques, puis ensuite dans leurs rapports avec d'autres notions connexes comme celles de lieu et de mouvement, en prenant pour base le Scholium qui fait suite aux définitions formulées au début des Principia mathematica philosophiae naturalis. La seconde partie analyse les arguments et precédés utilisés par Newton pour identifier des mouvements absolus, et prouver ainsi que de tels mouvements existent. La troisième (...) partie montre en quel sens il faut entendre que ces mouvements sont « absolus », et pourquoi on ne peut en tirer une preuve ultérieure de l'existence d'un temps et d'un espace absolus et subsistants.

In a first part I present the results of the philosophy of scientific explanation with an attempt to apply them to the case of the theory of evolution. Then I observe that the requirements of modelization of phenomena with the help of inductive logic do not capture efficiently the pertinent factors and fail just as much to exclude those which end up being neutral as explanatory premises. I then query in the direction of confirmation theory, and show that probabilistic reasoning (...) does not possess the syntactic means of testing evolutionary hypotheses in a way that would rely on a valid mode of inference. In a second part, I try to show how biology has oscillated between two privileged modes of explanation, the first one being through form of which I suggest here that it has never been replaced and that it has known a forgotten vitality in the middle and latter part of the 19th Century, and the second one being through function here evaluated critically alongside that of tinkering. Finally, some limits are seen to hold against the pretence to epistemological exclusivism of those two outlooks on the biological object. (shrink)

The article focuses on the implementation of a socio-technical device aimed at integrating services for older adults living with loss of functional autonomy in France. It unfolds in three parts. The first introduces the theories of innovation, the second presents the innovative model of integrated services, and the last part deals with the relationship that practitioners have with socio-technical devices that make up the innovation in the French context. It will be seen that this report is carried out in an (...) epistemic tension between a philic representation of these devices, which are supposed to bring about an expected renewal of professional and managerial practices, and a phobic representation, projecting on the innovation different fantasies as to their more or less explicit totalitarian character. Despite this tension, the real challenge is that of the coherence- as perceived by adopters of the innovation- between the principles underlying the innovation and the real will of its political promoters.

Schools located in underpriviledged areas have to deal with different factors, like the dropout rate among students and teachers; the culture of action, the culture of oral and a «carpe diem» culture; the low literacy rates; the type of children's knowledges — sometimes different from those promoted at school — and the learning difficulties of pupils... In light of these factors, few states have decided to adopt measures to support pupils and teachers in these communities. In this sense, several studies (...) examine the potential role of philosophy for children (P4C), but none examines, in this kind of environment, the integration of P4C in the context of a teaching field experience program. Insofar several novice teachers start their career in these environments, it could be helpful to enrich our comprenhension on this subject. This paper presents results from an exploratory study on this issue, which led to raise questions about the bachelor of education program, at least in our university. (shrink)

Les Œuvres respectives de Piaget et de Kuhn sont des études sur l'évolution d'un certain type de connaissance: la connaissance enfantine chez Piaget, la physique et la chimie chez Kuhn. Dans les deux cas, on essaie d'analyser les facteurs qui déterminent les changements des contenus de la connaissance, et les relations qui existent entre ces divers contenus successifs. Il nous semble qu'une comparaison de ces deux études révèle des convergences intéressantes pour la théorie de la connaissance.

In this contribution, we analyse the treatment of professional practice in two training sequences dedicated to the teaching of written French. Firstly, we examine the characteristics of the training devices organised with a combination of school field and training institution scheme. We then focus on interactions between trainer and trainees within two training activities aimed at sharing and reflecting on practicum. The interest of this double perspective lies in the understanding of knowledge circulation between school field and training institution and (...) how this circulation serves the development of teachers’ action.

Cet article souhaite élucider la philosophie de la chair développée par Michel Henry. Il s’agit de voir comment Henry parvient à penser la chair comme la possibilité principielle de l’individualité. Nous voulons montrer que la démarche henryenne repose non seulement sur une mise en question des canons de l’apparaître, mais également sur la conviction que le problème de l’individualité trouve sa solution dans une expérience charnelle radicale de soi-même permettant d’opérer un repli en-deçà du corps chosifié de la phénoménologie husserlienne. (...) C’est ce double mécanisme conceptuel qui permet à Henry de rejoindre l’individualité et de l’établir comme fondement de la vie in-ek-statique. (shrink)

Intersex is an umbrella term for variations in sexual characteristics. Although 1.7% to 4% of the population is born outside the framework of sexual binarity, the bodies of intersex people are pathologized and, according to medical specialists, in need of “repair”. This institutional stigmatization takes the form of sex reassignment surgery or hormone treatments, justified by socio-cultural premises based on heterosexist norms. Medical discourse is based less on the health, physical and psychological dangers of intersex patients than on safeguarding gendered (...) bicategorization. At the same time, individuals with intersex variations are demanding their right to self-determination, in particular through respect for their free and informed consent. Sex-assignment surgery, motivated and oriented by historically constructed gender binarity, lead to two types of epistemic injustice. A conceptual philosophical analysis of testimonial injustice and hermeneutic injustice will help us to understand the process of making intersex invisible through the epistemic relationship between intersex people and physicians.

This paper aims at introducing a French audience to the Intelligent Design debate. It starts by reviewing recent attacks on any possibility of a rational account of theism in light of the contemporary theory of evolution. A section is devoted to outlining the genesis of the "wedge" strategy, to distinguish it from young earth creationism, and to highlight the questioning of evolution as our meta-narrative bearing on overall conceptions of the scientific endeavor. The arguments propounded by Behe are reviewed in (...) detail, as the example of blood coagulation as a purported irreducibly complex mechanism is contrasted to the question of system boundaries. Counter-arguments by Miller are reviewed, and a few bottom-line questions are directed to invite a further consideration of the type of engineering this could testify to. The concept of complex specified information is then presented, and contrasted to traditional and lingering axiomatic problems in the theory of probabilities. The problem of the recognition of an intrinsic pattern is also brought together with some work in recent philosophy of causation and explanation. The two opposing strategies, naturalistic evolutionism and intelligent design, are seen as caught in each other's rhetoric, and some probing is offered in the direction of a theory that could surpass those stalling factors.

(Back Cover:) « La pensée métaphysique renaîtra demain. Ce sont des savants qui ont le goût et le sens de la pensée conduite jusqu’au terme de ses exigences internes, et des philosophes initiés aux sciences expérimentales qui, en commun, la feront. » L’œuvre de Claude Tresmontant (1925-1997) illustre parfaitement cette recherche de la métaphysique d’un monde en devenir, qui sait écouter et se modeler sur la transformation – la métamorphose – promise à une Création finalisée. Le trait commun aux exposés (...) ici présentés sous forme définitive a été cette recherche autour d’une pensée qui renouvelle de l’intérieur la métaphysique en réalisant le vœu de Bergson qu’elle devienne « auscultatrice », que l’énigme que pose l’homme face à son origine et sa destinée ne soit pas recouverte par une pensée qui se perdrait dans la description des choses ou dans l’esprit de système, mais qui non plus n’irait se recroqueviller sur elle-même, en narrant sa propre expérience subjective sous le mode de la déréliction. Claude Tresmontant a su penser l’être en genèse, et il a cherché à renouveler la question de l’existence de Dieu, en en transformant la problématique en dialogue avec les sciences contemporaines. À ce goût de l’être dont les sciences ont renouvelé l’approche, il a également voulu infuser un « supplément d’âme », en repensant la réalité de la création et l’horizon de la cause finale, toujours à partir de la nature ultimement théologique de la réponse à la question « qu’est-ce que l’homme ? » Contributeurs : Yves Tourenne, Philippe Gagnon, Fabien Revol, Brunor, Frédéric Crouslé, Bertrand Souchard, Emmanuel Gabellieri.

Freedom is first apprehended as the pursuit of an activity which implies the choice to defend a thesis among other possible ones. This translation of the problem of freedom in an articulate language presupposes a complex nervous system and sensory apparatuses which we take for granted. In this study, I try to explore the undergrounds of the problem of freedom along with the suggestion that the notion of coding could enable one to bridge nature and the mind. When organisms invent, (...) are they doing it in a spontaneous manner, inscribing in their hereditary and mnemonic instructions a stochastic contrivance of random accidents, or are they attempting to select among a limited number of schemes endowed with some optimality of functioning? If we consider them as submitted to physical forces, it is to the extent that we make them part of a strategy to extend the "laws" of a nature understood to respond passively. I suggest in this study that the epistemological understanding must regionalize itself and admit a hierarchy of dispositions in relation to the phenomenon of selection. I end by suggesting the pursuit of affirmation instead of negation, as this alone contains the requirement of integration to the knowing subject as well as the form in its act of understanding, without giving it a spontaneist position.

Nous nous proposons, dans cet article, d'examiner l'aspect philosophique de la pensée de Piaget sur la causalité, ainsi que sa critique des conceptions de Hume et de Kant. Mais une étape préalable s'jmpose d'abord, soit l'analyse des fondements empiriques de la pensée piagétienne. Nous ferons cette analyse en faisant un usage le plus discret possible du vocabulaire plutôt technique de Piaget.

In this public debate with Philippe Deterre (research director in immunology at the CNRS) – held at l'Enclos Rey in Paris' 15th district during the biennial Conference of the Réseau Blaise Pascal in March 2017 –, I defended the usefulness of natural theology. I first clarify theology's nature and understanding, then I speak about a tradition that upheld the public and exterior knowledge of God, and make an effort to show the presence of a theme reminiscent of natural theology behind (...) attempts at the good life. I then ask whether natural theology would only exist for the Christian. In the reply to my opponent's own reaction, I insist on the incongruity of separating our knowledge of God from our knowledge of science's wonderful discoveries, I ask whether nature could be said to be crafty and "ingenious," and I conclude by building a case for the return of God in public conversation, as part of an effort that our world needs in terms of finding back its compass, and restoring an ideal of living rationally.

Dans ce texte, je suggère que les personnes souffrant d’anorexie mentale s’infligent une forme particulière de violence épistémique lorsqu’elles ignorent volontairement les symptômes de leur maladie. Pour ce faire, dans une démarche inspirée par celle de Havi Carel, je présente d’abord le rapport particulier qu’entretiennent les personnes souffrant d’anorexie avec leur corps, et ce, à l’aide de trois axes d’analyse empruntés à Susan Bordo, soit le dualisme Corps/Esprit, les idéaux de contrôle et d’autonomie, et les rapports de genre. Je propose (...) ensuite le concept de violence épistémique auto-infligée en montrant que l’ignorance volontaire de la faim a pour objectif de préserver l’identité des personnes vivant avec cette maladie comme autonomes et en contrôle, autrement dit comme n’étant pas « malades ».

L'individualité est un thème largement exploité par les sciences sociales et la psychologie, mais, sans doute, trop peu par la philosophie.

Le respect de la vie privée et de l’intimité est un droit reconnu aux usagers des services de santé et des services sociaux par différents codes d’éthique, par la Charte des droits et libertés de la personne du Québec et par la Loi sur les services de santé et les services sociaux. Pour autant, la signification que prend ce droit demeure incertaine. Il n’y a pas une signification, mais bien des significations. S’appuyant sur un important travail d’observation dans deux comités (...) d’éthique clinique situés dans des établissements de santé et de services sociaux, les auteurs présentent et analysent ici un certain nombre de situations litigieuses dans lesquelles une interprétation du droit à la vie privée et à l’intimité a été faite. Au terme de l’exercice, il ressort entre autres que, selon les situations analysées, les discussions qui se font dans les CÉC conduisent à des modalités différentes (« déplacement et hiérarchisation », « opposition et évitement », « ouverture et compromis », « élargissement et remise en question ») qui ont pour effet de changer le regard porté sur l’usager et plus spécifiquement de faire comprendre son point de vue. En outre, si le droit à la vie privée et à l’intimité contribue à modifier l’interprétation que l’on se fait d’une situation ou des usagers, il est lui-même objet d’interprétation. C’est la diversité de sens qu’il peut prendre qui lui préserve son pouvoir d’interroger. (shrink)

Taking as a starting point for his quest the teaching received from the Hebrew prophets and transmitted by the people of Israel, Claude Tresmontant identifies in it the specific moment where an entirely new and creative thought is introduced in the history of mankind. Trained in philosophy of science and conscious of the discipline involved in a rigorous experimental method as a key to valid and true knowledge, Claude Tresmontant boldly recreated bridges, long destroyed, between science and philosophy of nature, (...) as well as metaphysics and theology. Following an immense effort, he has found back, stringently and often on his own, a unifying concept capable of integrating the experience and the questions of today's man: "...the central question is that of integrating the teaching of creation and that of revelation in the unity of an intelligible vision of the world, desirable, and verifiable..." as he said himself in the preface to L'histoire de l'univers et le sens de la Création. This immense, powerful and thought-provoking work is here presented by a young philosopher, long time correspondent of Claude Tresmontant, who benefited from decisive moments of encounter with him.

Résumé Dans ce texte, l’autrice explore différents enjeux proprement féministes qui émergent de l’industrie de la mode, notamment dans les secteurs de la production, de la vente et de la commercialisation des vêtements. Elle s’intéresse également à la manière dont les images produites par l’industrie de la mode participent à renforcer l’objectivation des corps féminins. S’en suit un retour sur les travaux de Beauvoir, Garcia, Dolezal et Bordo sur l’être-au-monde féminin, qui signifie d’exister-pour-autrui et de se faire objet de désir. (...) Ces réflexions sont mises en parallèle avec les travaux de Young et de Froidevaux-Metterie, selon qui le plaisir de se vêtir participe à l’appropriation et à l’augmentation de la subjectivité. L’autrice propose alors de concilier valeurs féministes non oppressives avec le besoin existentiel d’être et de se reconnaître que le vêtir permet en grande partie de combler, en adoptant des pratiques de mode lente.

This is a critical notice/review essay on *L'embryogenèse du monde et le Dieu silencieux*, a manuscript completed by Raymond Ruyer in the early 1980s. It came out as a monograph in November 2013, with the Éditions Klincksieck in Paris. It offers a presentation in an organized fashion of many aspects of his thought. Ruyer considered that a book about God could only be churned into a series of chapters on the unachievable character of our knowledge in different domains of human (...) inquiry. The nature of this final solution on God's relationship to the world and to natural forms is here assessed critically. (shrink)
