Tout ce qui est dans l'oeuvre de Jacques, nous l'avons d'abord vécu à l'état de difficulté vitale et d'expérience, - les questions de l'art et de la morale, de la philosophie, de la foi, de la prière, de la contemplation. Cela nous a d'abord été donné à vivre, à chacun selon sa nature et la grâce de Dieu », notait Raïssa en 1934. Cette correspondance confirme le propos, qui nous fait pénétrer dans « l'amour fou » de deux vies données (...) l'une à l'autre, et la trame quotidienne de leur fécondité de pensée et de « grandes amitiés ».Leur conversion en 1906 scelle la vocation d'un couple venu déjà un peu d'ailleurs : lui, 18 ans, romantique, révolutionnaire et dreyfusard en diable, en rupture avec les élites républicaines laïques dont il est issu ; elle, 17 ans, comme sortie d'une peinture de Chagall, juive et slave en quête à la Sorbonne d'une nouvelle patrie spirituelle. Les premiers regards portés sur eux discernent déjà leur promesse : « Je les trouve absolument dignes l'un de l'autre ; ce sont même de si beaux types d'humanité qu'il faut se féliciter de les voir se rechercher. On ne trouve pas si souvent de couple bien assorti ; celui-là me paraît devoir donner un exemple lumineux. »Ils s'écrivent abondamment dès que les aléas de la vie les séparent et ce premier tome les suit dans la découverte d'eux-mêmes. Dans la discontinuité des circonstances, leur chemin métaphysique et mystique progresse, tandis que se révèle, derrière chaque ouvrage, chaque combat, chaque accompagnement spirituel, le secret de leur rayonnement : au fil de ces 712 lettres, c'est d'abord une histoire d'amour, dans un respect tendre et sacré de la singularité de l'autre.

This paper explores a specific problem within an important philosophical genre of the fourteenth century: the debates over the perfection of species. It investigates how the problem of defining limits for continuous magnitudes – a problem typical of Aristotelian physics – was integrated into these debates at the levels of genera, species, and individuals as these entities began to be conceptualized in quantitative terms. After explaining the emergence of this problem within fourteenth-century metaphysics, the paper examines the contributions of three (...) philosophers – Hugolinus of Orvieto, John of Ripa, and Paul of Venice – who offered varying solutions to the challenge of defining limits between species. It demonstrates that two primary solutions arose, inspired by continuous and discrete mathematical objects. It is shown that whereas Hugolinus of Orvieto advocates for a continuist model, John of Ripa proposes a discrete one. The last part of the paper examines Paul of Venice's hybrid approach, which combines elements from both models, facilitating a more comprehensive treatment of species particularly difficult to analyse, namely geometric figures. The conclusions of this comparative study underscore how profoundly the metaphysical reflections of the Middle Ages contributed to the analysis of the structure of the continuum and the extension of the notion of quantity to various objects.

Over the last 40 years or so, there has been an explosion of cultural evolution research in anthropology and archaeology. In each discipline, cultural evolutionists investigate how interactions between individuals translate into group level patterns, with the aim of explaining the diachronic dynamics and diversity of cultural traits. However, while much attention has been given to deterministic processes, we contend that current evolutionary accounts of cultural change are limited because they do not adopt a systematic stochastic approach. First, we show (...) that, in contrast with the intense debates in ecology and population genetics, the importance of stochasticity in evolutionary processes has generated little discussion in the sciences of cultural evolution to date. Second, we speculate on the reasons, both ideological and methodological, why that should be so. Third, we highlight the inadequacy of genetically-inspired stochastic models in the context of cultural evolution modelling, and ask which fundamental stochastic processes might be more relevant to take up. We conclude that the field of cultural evolution would benefit from a stochastic revolution. For that to occur, stochastic models ought to be developed specifically for cultural data and not through a copy-pasting of neutral models from population genetics or ecology. (shrink)

We provide characterizations of the equal division values and their convex mixtures, using a new axiom on a fixed player set based on player nullification which requires that if a player becomes null, then any two other players are equally affected. Two economic applications are also introduced concerning bargaining under risk and common-pool resource appropriation.

This paper presents a version of hylomorphism that intends to solve problems faced by contemporary hylomorphism. After showing that attempts to understand form as sets or relation of essential properties fail at taking into account the dynamic development of substances, the paper suggests another version of hylomorphism able to solve these difficulties. A functionalist version of hylomorphism is then defended: the best way to understand how form can be present throughout all the developmental stages of a substance is to understand (...) it as a certain kind of function.

In this collection of essays, Bromberger explores the centrality of questions and predicaments they create in scientific research. He discusses the nature of explanation, theory, and the foundations of linguistics.

Intuitive predictions and judgements under uncertainty are often mediated by judgemental heuristics that sometimes lead to biases. Our micro-developmental study suggests that a presumption of rationality is justified for adult subjects, in so far as their systematic judgemental biases appear to be due to a specific executive-inhibition failure in working memory, and not necessarily to a lack of understanding of the fundamental principles of probability. This hypothesis was tested using an experimental procedure in which 60 adult subjects were trained to (...) inhibit the classical conjunction bias on a frequency judgement task derived from Tversky and Kahneman's work. Pre- and post-test performance was assessed via a probability judgement task. The data indicated a training effect, suggesting that subjects traditionally labelled as "irrational" with respect to the classical rules of inductive reasoning are in fact "inefficient inhibitors". These findings are discussed in terms of a polymorphous view of rationality. (shrink)

Émile Saisset (1814-1863) est un philosophe aujourd’hui bien oublié, bien qu’il ait été un insigne représentant de « l’école éclectique » qui a dominé l’enseignement de la philosophie en France entre 1820 et les années 1860. Au sein de cette école, il fut celui qui entretint avec le catholicisme un dialogue constant, et un des représentants les plus distingués du spiritualisme philosophique. Ce dialogue repose en partie sur la volonté de définir un nouveau magistère dans la société post-révolutionnaire, qui tienne (...) à la fois compte de la tradition portée par le christianisme et des nécessités d’affronter la « modernité ». Il a rêvé d’un concordat philosophique avec le christianisme. Il y avait une part de stratégie dans cette démarche, et les contemporains, comme les philosophes de la fin du siècle, n’ont pas manqué d’y voir une part d’hypocrisie. En réalité, il y avait aussi dans sa démarche une « inquiétude métaphysique », reposant sur les modalités d’articulation entre foi et raison dans un régime de société d’opinions. Si Émile Saisset a été oublié, c’est parce que la séquence historique qu’il incarne a été ensevelie sous la laïcité républicaine. Et pourtant, sa pensée et son action témoignent pour la construction française d’une acception spirituelle et philosophique du gouvernement politique. (shrink)

The Newell Test is an ambitious and promising project, but not without pitfalls. Some of the current criteria are not theoretically neutral, whereas others are unhelpful. To improve the test, the learning and development criteria are reviewed and revised, which suggests adding a maturation criterion as well. Such changes should make the Newell Test more general and useful.

Misunderstanding of the dynamical behavior of the ventilatory system, especially under assisted ventilation, may explain the problems encountered in ventilatory support monitoring. Proportional assist ventilation (PAV) that theoretically gives a breath by breath assistance presents instability with high levels of assistance. We have constructed a mathematical model of interactions between three objects: the central respiratory pattern generator modelled by a modified Van der Pol oscillator, the mechanical respiratory system which is the passive part of the system and a controlled ventilator (...) that follows its own law. The dynamical study of our model shows the existence of two crucial behaviors, i.e. oscillations and damping, depending on only two parameters, namely the time constant of the mechanical respiratory system and a cumulative interaction index. The same result is observed in simulations of spontaneous breathing as well as of PAV. In this last case, increasing assistance leads first to an increase of the tidal volume (VT), a further increase in assistance inducing a decrease in VT, ending in damping of the whole system to an attractive fixed point. We conclude that instabilities observed in PAV may be explained by the different possible dynamical behaviors of the system rather than changes in mechanical characteristics of the respiratory system.

This paper examines the discussion about false pleasures in the "Philebus" (36 c3-44 a11). After stressing the crucial importance of this discussion in the economy of the dialogue, it attempts to identify the problematic locus of the possibility of true or false pleasures. Socrates points to it by means of an analogy between pleasure and doxa. Against traditional interpretations, which reduce the distinction drawn in this passage to a distinction between doxa and pleasure on the one hand and their object (...) on the other, it is argued that, rather, Socrates distinguishes between the mere fact of having a doxa or a pleasure, on the one hand, and the content of these acts, on the other hand. Consequently, the possibility for a pleasure to be false does not concern its relation to an object, but the affective content which defines it. In order to show how the affective content of a pleasure can be false, it is necessary to examine the three species of false pleasures described by Socrates in their relation to appearance and imagination. Appearance is not identical with perception for Plato: it consists in a mixture of perception and doxa. As for imagination, it consists in "illustrating" a doxa present in the soul by means of a "quasi-perception". It is the presence of a doxa in each of these processes which makes it possible for them to be true or false, while mere perception cannot be either true or false. It is then argued that according to the "Philebus" pleasure can be false precisely because its affective content is not a mere perception, but either an appearance or an imagination. (shrink)

This paper studies ‘minority’ initiatives to organize sports games. A meta-analysis of published data in the literature identifies the formal appearance taken by each of these initiatives under the Olympic model. But it also conduces to build a number of indicators to answer a series of questions about their logic and strategies. All the initiatives studied are based on an ambivalent posture that, while based on the denunciation of a discriminating space, claim access to it. By an astonishing paradox, ‘non-normative’ (...) actors are driven to reclaim a model that, under cover of Universal, aims to establish a norm that is situated and dated. In practice, they use two types of strategies: a strategy for participation in the Olympics to transform them into a space which represents a fight against exclusion, or a strategy to create alternative events. Whatever the strategy, these initiatives are implemented according to their objectives. Differentiated in their forms—participatory or autonomy—they are also in their purpose. The comparison of these initiatives shows that ultimately, beyond strategies and logic inherent in different social, historical and organizational contexts, the mobilizations of the actors reveal the same ambivalence about the sports model conveyed by the Olympic institution.

In this article, I examine the way Aristotle makes use of the methods Plato labelled as "dialectic". After suggesting a unified interpretation of Plato’s dialectic, I show that Aristotle makes room for them not inside the context of demonstrative science, but at the level of the investigation concerning the principles of such a science. These principles are, for the most part, definitions; and Plato’s dialectical methods are designed to search for and obtain definitions. Although Aristotle, contrary to Plato, seems to (...) distinguish between dialectic and philosophy, he relates both to the same capacity, and he suggests that their methods are identical up to a certain point. Moreover, the cognitive state corresponding to dialectic is, for Aristotle as for Plato, intelligence (nous). Nevertheless, there remain important differences between Plato and Aristotle on this issue: while the dialogical dimension of dialectic is for Plato constitutive of philosophy and implies that the philosophical thought is a perpetual motion, it is according to Aristotle what distinguishes dialectic from philosophy, which must for its part come to a rest; and while philosophy presupposes a rupture with sensation according to Plato, Aristotle envisages it in continuity with sensible experience.

On n'a jamais bien jugé l'empirisme, supposant d'emblée qu'il était l'opposé du rationalisme. En fait, qu'il s'agisse de l'empirisme ou du rationalisme, on déploie dans chaque cas une chaîne de séquences dont il s'agit de rendre les termes solidaires: rationalisme ═ a priorisme ═ principes généraux abstraits ═ raison universelle ═ idéalisme ═ la vérité est raison pure empirisme ═ a postériorisme ═ pas de principes généraux abstraits ═ pas d'ordre rationnel ═ positivisme ═ réalisme.

A new class of values combining marginalistic and egalitarian principles is introduced for cooperative TU-games. It includes some modes of solidarity among the players by taking the collective contribution of some coalitions to the grand coalition into account. Relationships with other class of values such as the Egalitarian Shapley values and the Procedural values are discussed. We propose a strategic implementation of our class of values in subgame perfect Nash equilibrium. Two axiomatic characterizations are provided: one of the whole class (...) of values, and one of each of its extreme points. (shrink)

Using the matching bias example, the aim of the present studies was to show that adults' reasoning biases are due to faulty executive inhibition programming. In the first study, the subjects were trained on Wason's classical card selection task; half were given training in how to inhibit the perceptual matching bias (experimental group) and half in logic without the inhibition component (control group). On the pre- and post-tests, their performance was assessed on the Evans conditional rule falsification task (with a (...) negation in the antecedent of the rule), a task that also involves matching bias. In addition, subjects were tested for perceptual field dependence/independence using the Embedded Figures Test. The results brought out a specific inhibition training effect, as well as a clear-cut relationship in the experimental group between receptiveness to training and perceptual field independence. In the second study, the training paradigm was the same except that on the pre- and post-tests, the negation was in the consequent of the conditional rule (in this case, the perceptual matching response corresponds to the logical response). The subjects succeeded on the pre-test, and the matching-bias inhibition training had a negative effect on post-test performance. This specific negative priming effect confirms the inhibitory impact of our experimental training and outlines the dissociation of inhibition and logical components. (shrink)

This article focuses on the methodological issues involved in combining data collected by questionnaire and interview to study the barriers to educational and professional participation of young people (aged 15-26) living with cystic fibrosis. In addition to an exploratory survey of thirteen professionals, it is based on the cross-referencing of data produced from a short and adapted version of the Measure of the Quality of the Environment-MQE (n=100) and interviews of the “story of life and practices” type with high school (...) students, students, young people looking for work or in employment (n=29). The results show the discrepancy between the responses to the MQE and the narratives produced in the interviews. On the one hand, the responses to the MQE shed light on the impact of the physical environments and the spatial and temporal organisation of the school and work environments on the experience of disability. On the other hand, they seem to underestimate the weight of human environments in producing or reducing barriers to participation. The testimonies gathered in interviews allow us to reassess the importance of these environments. The use of mixed research methods therefore seems essential to understand the respective roles of the material and human components of environments in the production of educational and occupational disability.

Ce texte est consacré à la conception de la liberté absolue chez Schelling, telle qu’elle est exposée dans les Weltalter et accomplie dans la philosophie tardive. À partir d’une élucidation des rapports entre liberté, nécessité et contingence, nous souhaitons montrer que Schelling parvient à développer un nouveau concept de liberté absolue qui d’une part ne concerne pas seulement Dieu mais aussi l’homme, et qui d’autre part dépasse la liberté kantienne comme autonomie et autodétermination, mais aussi la liberté de l’É crit (...) sur la liberté de 1809 comme « pouvoir du bien et du mal ». En outre, nous soutenons que la liberté du Dieu « Seigneur de l’être » de la philosophie de Munich et Berlin se distingue de celle du Dieu seulement « sur-étant » des Weltalter. Seule la « liberté d’être et de ne pas être » du « Seigneur de l’être » représente une forme de liberté à laquelle l’homme peut et doit tendre, une liberté non pas de l’auto-anéantissement, mais du don de soi, liberté suprême qui n’est autre que celle de l’amour.

For Merleau-Ponty and Maldiney, the world of the pictorial image is “an almost crazy world” and a world of “confused sensations”. However, it is not only an illusory and chimeric world, cut off from the real world. Indeed, far from distancing us from the real world, this craziness and this confusion bring us back to it. The objective of this essay is therefore to question the relationship between pictorial art and the real (not fictional or imaginary) world. Certainly, the pictorial (...) work of art makes us return “to the things themselves”, because it establishes a conversion of the gaze and a metamorphosis of the visible. But one can ask if this conversionof the gaze does not reverse the movement of phenomenological “reduction” as described by Edmund Husserl, since it plunges us into the very heart of the world and does not imply any abstention or abstraction. For Maldiney as for Merleau-Ponty, painting reveals our original being-in-the-world, so that it will be necessary to elucidate what it means exactly. Moreover, we will investigate the role of style and rhythm as well as the role of color and the line in order to describe more precisely the connection between the world and the work of art, between continuity and discontinuity. Finally, we will propose another meaning of the word “image”in order to highlight the ethical function of the image thus understood. (shrink)

Les recherches sur le travail comme valeur au Moyen Âge se sont principalement attardées sur la malédiction prononcée lors de l'expulsion du jardin d'Eden, négligeant l'activité à laquelle se livrait Adam avant la chute (Gn 2,15). A la suite de Philon d'Alexandrie, Augustin a proposé une lecture littérale de ce premier travail, qui a eu un fort impact dans la culture médiévale, certains auteurs (franciscains) comprenant ce verset au sens d'une mission d'améliorer encore la création.

Le Liber ostensor quod adesse festinant tempora, rédigé en 1356 dans la prison du Soudan à Avignon, est le plus important des écrits conservés du visionnaire et prophète et franciscain Jean de Roquetaillade. Son édition, par une équipe dirigée par A. Vauchez, offre des matériaux très riches pour l'histoire religieuse et culturelle du XIVe siècle. On note toutefois quelques lacunes dans la bibliographie et l'identification des sources, et notamment dans la notice consacrée aux emprunts faits à Pierre de Jean Olivi. (...) Au-delà des citations explicites, on peut mettre en évidence une dépendance bien plus grande, que masque pour partie une stratégie d'écriture carcérale. (shrink)

Autour de 1100, pour les jeunes femmes de l’aristocratie éduquées dans des monastères, l’écriture de lettres d’amour fictives à leur maître de rhétorique constituait un apprentissage aussi bien littéraire qu’émotionnel. Comme le rappelle Barbara Newman, les Epistolae duorum amantium, correspondance échangée par Héloïse et Pierre Abélard durant leur liaison, doivent se comprendre dans cette lumière. Leur singularité tient largement au fait qu’Héloïse a choisi de donner corps à une figure poétique, en s’identifiant aux héroïnes tragiques d’Ovide.

Neuroconstructivism: How the Brain Constructs Cognition proposes a unifying framework for the study of cognitive development that brings together (1) constructivism (which views development as the progressive elaboration of increasingly complex structures), (2) cognitive neuroscience (which aims to understand the neural mechanisms underlying behavior), and (3) computational modeling (which proposes formal and explicit specifications of information processing). The guiding principle of our approach is context dependence, within and (in contrast to Marr [1982]) between levels of organization. We propose that three (...) mechanisms guide the emergence of representations: competition, cooperation, and chronotopy; which themselves allow for two central processes: proactivity and progressive specialization. We suggest that the main outcome of development is partial representations, distributed across distinct functional circuits. This framework is derived by examining development at the level of single neurons, brain systems, and whole organisms. We use the terms encellment, embrainment, and embodiment to describe the higher-level contextual influences that act at each of these levels of organization. To illustrate these mechanisms in operation we provide case studies in early visual perception, infant habituation, phonological development, and object representations in infancy. Three further case studies are concerned with interactions between levels of explanation: social development, atypical development and within that, developmental dyslexia. We conclude that cognitive development arises from a dynamic, contextual change in embodied neural structures leading to partial representations across multiple brain regions and timescales, in response to proactively specified physical and social environment.

In this brief commentary, we present a critical reflection on trait emotional intelligence (EI) theory and research as covered in a recent narrative review (Petrides et al., 2016). We consider (a) whether synthesising research findings that use different conceptualisations of EI is desirable, (b) if the measurement of trait EI might become more diverse, (c) whether trait EI research in interpersonal settings requires additional analytical thought, and (d) how researchers might go about objectively conceptualising trait EI. Our collective focus is (...) on EI measurement as it relates to the development of trait EI theory and research in the future. (shrink)
