Les concepts dont les sciences font usage ne sont pas neutres, notamment lorsqu'ils s'appliquent au vivant. Ils se construisent suivant des déterminations spécifiques en fonction des époques, des idéologies humaines et possèdent l'originalité de porter un propos sur le vivant émanant du vivant lui-même. Ceci n'est pas sans incidence sur les différents champs d'application des sciences du vivant comme la médecine ou la thérapeutique. La présente étude s'intéresse au geste particulier auquel invite Georges Canguilhem dans son essai Le normal et (...) le pathologique. C'est sur ce geste, hautement philosophique, que s'appuient les prémisses d'une épistémologie des concepts. Toujours en acte, cette dernière ouvre la question des normes et de l'erreur rapportée au vivant. Elle est l'occasion d'une redécouverte de la richesse authentique de l'état pathologique permettant au vivant qui s'étudie de mieux se connaître. (shrink)

La réflexion philosophique, dont l'ouverture à l'univers dans lequel nous nous découvrons - avec une acuité proportionnelle à un étonnement renouvelé - n'a pas de limites, n'en est que plus tributaire des sciences et des techniques, des arts et de multiples activités qui régissent plus ou moins fructueusement notre expérience. Or, au sein des sciences humaines, privilégiées pour éclairer une condition que nous ne saurions cesser d'interpréter, peu d'oeuvres du dernier siècle auront enrichi en le précisant notre être-au-monde, comme la (...) théorie linguistique de Gustave Guillaume, assez solitaire, et les recherches multiformes de Jean Piaget - où la psychologie de l'enfant a souvent occulté la visée épistémologique et son enracinement biologique (cf Biologie et connaissance, 1967) et ses prolongements pédagogiques, voire éthiques. Le Cinquantenaire et le Trentenaire de leur disparition appelaient un hommage d'autant plus impératif qu'ils sont restés marginaux ou ignorés dans les milieux philosophiques, malgré la centralité de leurs élucidations. Leur commune orientation génétique et structurale n'ayant suscité aucun échange, pendant la contemporanéité de publications d'un tiers de siècle (1923-1960), mesurer leur complémentarité s'impose d'autant plus. S'ils peuvent aider à repenser la condition humaine, c'est qu'ils auront contribué à dissiper le "mystère de la pensée". L'un cherchant à habiliter les caractères systématique et cinétique des langues, irremplaçables moyens de penser ; l'autre dans un vis-à-vis cognitif et opératoire de Freud, en relavant sur les plans épistémologique et logique, notamment, l'élan révolutionnaire de la seconde modernité, autour de l'évolutionnisme. Mais les thèmes majeurs du constructivisme, du schème et de la symbolisation - et plus largement du temps et du langage - auront sans doute aidé à spécifier les mutations autorisées par la révolution critique. Entre l'Instant du je parle et un décentrement exigible pratiquement (éthique) comme théoriquement (épistémique), c'est bien la condition humaine dans son ensemble qui est concernée. Si repenser cette Condition s'impose en permanence, il importe de ne pas manquer des oeuvres qui, par-delà toute mode, proposent à notre expérience des fondations résistant à d'inéluctables vicissitudes.

Guillaume Collett questions to what extent we can locate Deleuze within the Lacanian School during the late-1960s, prior to Guattari. In so doing, he offers a new, integrated reading of Deleuze's The Logic of Sense by understanding it as a 'psychoanalysis of sense', and gives a new interpretation of Deleuze's conception of philosophy itself. The Psychoanalysis of Sense shows that Deleuze was not merely aware of the debates animating the Lacanian School during the 1960s: he sought to contribute to (...) them. Emphasising his appropriation of the work of post-Lacanian Serge Leclaire, Collett explains how Deleuze constructed a more singular and immanent theory of the linguistic structure of the unconscious - granting the erogenous body a larger structuring role.

L'hypothèse que l'on proposera ici est que le dispositif du «médecin de la civilisation» monté par Deleuze en 1962 dans sa lecture de Nietzsche, loin de pouvoir être généralisé comme tel (comme si la suite de l'oeuvre n'en était que l'application différée ou même la continuation par d'autres moyens), n'y est effectivement agissant qu'à force de décaler l'énonciation deleuzienne par rapport à l'instance de la philosophie clinique qu'il définit. Et que pour cette raison, la figure du philosophe médecin de la (...) civilisation permet d'autant mieux de problématiser certaines difficultés que rencontre la tâche d'une symptomatologie des modes collectifs d'existence. À prendre cette tâche au sérieux, j'avancerai enfin que le déplacement du dispositif nietzschéen de part et d'autre de la rencontre avec Guattari et de L'Anti-OEdipe, trouve un point de résolution, ou en tout cas de cohérence et d'équilibre, dans la détermination d'une pratique analytique sui generis, celle-là même que Guattari nommera «schizo-analyse», et plus spécifiquement dans le concept d'agencement qui, de L'Anti-OEdipe à Mille plateaux, en supportera de plus en plus clairement les coordonnées propres.

In this paper, we use an experimental design to compare the performance of elicitation rules for subjective beliefs. Contrary to previous works in which elicited beliefs are compared to an objective benchmark, we consider a purely subjective belief framework. The performance of different elicitation rules is assessed according to the accuracy of stated beliefs in predicting success. We measure this accuracy using two main factors: calibration and discrimination. For each of them, we propose two statistical indexes and we compare the (...) rules’ performances for each measurement. The matching probability method provides more accurate beliefs in terms of discrimination, while the quadratic scoring rule reduces overconfidence and the free rule, a simple rule with no incentives, which succeeds in eliciting accurate beliefs. Nevertheless, the matching probability appears to be the best mechanism for eliciting beliefs due to its performances in terms of calibration and discrimination, but also its ability to elicit consistent beliefs across measures and across tasks, as well as its empirical and theoretical properties.

In this paper, I discuss the distribution and the interpretation of the temporal suffix -kue in Mbyá, a Guaraní language that is closely related to Paraguayan Guaraní. This suffix is attested both inside noun phrases and inside clauses. Interestingly, its nominal uses give rise to inferences that are unattested in its clausal uses. These inferences were first identified in Paraguayan Guaraní by Tonhauser, who called them the existence property and the change of state property. Tonhauser further argued that these properties (...) are built into the lexical entry of the nominal temporal marker -kue. By contrast, I argue that -kue denotes a relative past tense both in its nominal and clausal uses, and that the existence and change of state properties are pragmatic inferences that arise from the interaction of the literal meaning of -kue with general constraints on the interpretation of noun phrases, notably constraints on the topicality of the time of evaluation of noun phrases. This allows me to maintain a uniform analysis of -kue across its nominal uses and its clausal uses. The analysis of -kue in Mbyá is relevant to a number of current debates on the expression of tense crosslinguistically. Firstly, the existence of relative tenses has sometimes been called into question. Klein notably argues that relative tenses are actually combinations of tense with the perfect aspect. Others have argued that there exist true relative tenses in certain languages. I argue that facts of Mbyá support the latter view. Secondly, Klein famously defined tenses as relations between topic times and the time of utterance. I argue, on the other hand, that relative tenses only denote relations between times, and that the topicality or non-topicality of their temporal arguments depends on their context of use, including their syntactic environment. Thirdly, this paper contributes to debates on the nature and reality of nominal tenses The Oxford handbook of tense and aspect, 2012), by arguing that tense in Mbyá is a genuinely nominal category, in the sense that temporal functional projections are part of the extended projection of the noun phrase.

Representing an epistemic situation involving several agents obviously depends on the modeling point of view one takes. We start by identifying the types of modeling points of view which are logically possible. We call the one traditionally followed by epistemic logic the perfect external approach, because there the modeler is assumed to be an omniscient and external observer of the epistemic situation. In the rest of the paper we focus on what we call the internal approach, where the modeler is (...) one of the agents involved in the situation. For this approach we propose and axiomatize a logical formalism based on epistemic logic. This leads us to formalize some intuitions about the internal approach and about its connections with the external ones. Finally, we show that our internal logic is decidable and PSPACE-complete.

Pour Hegel, le sens s’élabore dans le langage, mais l’usage du langage ne fait pas nécessairement sens. Au niveau du discours, il semble même qu’un problème inévitable survienne. Si l’expérience d’un sens s’élaborant dans le langage ne s’accomplit que sous la forme d’un système autoréférent, comment ce sens peut-il se communiquer sans se contredire? Hegel n’échappe pas à ce problème si bien que l’on peut se poser la question de savoir si la dialectique du système est compatible avec les éléments (...) dialogiques (préfaces, notes, etc.) qui visent à l’instanciation de ce système? Nous montrons alors que pour nouer l’autoréférence du sens à l’idée de communication, Hegel présuppose le moyen terme d’un esprit commun, un "Nous". À partir de celui-ci, nous construisons un modèle dialogique et autoréférent qui dessine certains enjeux propres aux philosophies contemporaines de la communication. (shrink)

In the 1990s, large insurance companies failed in virtually every major market, prompting a fierce and ongoing debate about how to better protect policyholders. Drawing lessons from the failures of four insurance companies, When Insurers Go Bust dramatically advances this debate by arguing that the current approach to insurance regulation should be replaced with mechanisms that replicate the governance of non-financial firms.Rather than immediately addressing the minutiae of supervision, Guillaume Plantin and Jean-Charles Rochet first identify a fundamental economic rationale (...) for supervising the solvency of insurance companies: policyholders are the "bankers" of insurance companies. But because policyholders are too dispersed to effectively monitor insurers, it might be efficient to delegate monitoring to an institution--a prudential authority. Applying recent developments in corporate finance theory and the economic theory of organizations, the authors describe in practical terms how such authorities could be created and given the incentives to behave exactly like bankers behave toward borrowers, as "tough" claimholders.

We question the idea that the mirror neuron system is the substrate of social affordances perception, and we suggest that most of the activity seen in the parietal and premotor cortex of the human brain is independent of mirroring activity as characterized in macaques, but rather reflects a process of one's own action specification in response to social signals.

InFellow Creatures, Christine Korsgaard claims that human beingsoughtto treat all sentient animals as ends in themselves. However, in this article, I argue that Korgaard's method goes beyond what a coherent constructivist conception allows, and I claim that we should therefore adopt a Humean rather than a Kantian version of constructivism. I believe that such a conception permits us to hold substantial ethical positions about non-human animals without having to compromise our ontological commitments.

Corporate codes of ethics, which have spread in the last decades, have shown a limited ability to foster ethical behaviors. For instance, they have been criticized for relying too much on formal compliance, rather than taking into account sufficiently agents and their moral development, or promoting self-reflexive behaviors. We aim here at showing that a code of ethics in fact has meaning and enables ethical progress when it is interpreted and appropriated with practical wisdom. We explore a model that represents (...) an uncommon organizational code of ethics: the monastic Rule of St. Benedict, written in the sixth century and still used today. Our empirical study—conducted in several monasteries living under this rule—shows that organization members interpret this rule, both hermeneutically and ethically, to adapt it to situations. They also appropriate this rule as a way of life and treat it as a dynamic framework that helps them to follow their purpose within their organization. This exceptional code actually offers an alternative model for practicing codes of ethics, in a virtue-ethical manner, beyond mere compliance with the text. The way in which reflexive and active agents practice the code, both individually and collectively, shapes their organizational experience and fosters their moral development. (shrink)

A l'automne de 1534, alors que le débat religieux en France est dominé par l'interférence des doctrines luthériennes et sacramentaires, et soudainement dramatisé par l'" affaire des Placards ", Guillaume Budé - tout en jetant sur son temps un regard lucide et souvent prophétique - écrit le livre qui couronne une quête spirituelle de plus de vingt années, justifiant ainsi (au sens théologique du terme) sa propre vie intellectuelle et l'humanisme dont il est le champion. Ce " livre-testament ", (...) tout vibrant d'une éloquence tendue, somptueuse et savante, opère dans sa complexe écriture le transfert de toutes les ressources des lettres profanes (dont le mot hellénisme est l'indice) au christianisme.

The confrontations of stakeholder visions about agriculture and food production has become a focal point in the public sphere, coinciding with a diversification of agrifood models. This study analyzes the debates stemming from the coexistence of these models, particularly during the initial term of neoliberal-centrist Emmanuel Macron’s presidency in France. Employing collective monitoring from 2017 to 2021, a corpus of 958 online news and blog articles was compiled. Using a computational analysis, we reveal the framings and controversies emerging from this (...) media discourse. The macro-structuring of discourse on model coexistence revolves around scientific, economic and political framings. Coexistence is a complex of debates based on specific frames associated with specific arenas and actor configurations: growth of organic agriculture, transformations of agrifood systems, sciences of production and impacts, livestock and meat diet controversies, agroecological innovations, CAP reform criticism, discourse of peasant agriculture and State-Profession _co-gestion_. Employing global sentiment analysis and focusing on salient controversies, namely EGAlim law, pesticide regulations, and agribashing, we show the shift from conciliation to a hardening of debates. Finally, we discuss the causes and consequences of this trend. The political will to support the transition of agriculture remains influenced by the _co-gestion_ system, an inherited configuration of decision-makers instrumental in the agricultural modernization. As a consequence, significant agricultural challenges, particularly highlighted in the scientific macro-frame, persist unresolved. This lock-in of the agrifood system is based on defensive strategies that challenge the democratic debate about food and agricultural practices. (shrink)

La notion d’ordre public trouve des expressions diverses dans la norme constitutionnelle. Tantôt norme d’habilitation, tantôt moyen de conciliation entre des principes constitutionnels antagonistes, l’ordre public est un objectif de valeur constitutionnelle qui s’impose au législateur et qui est susceptible de restreindre l’exercice de certaines libertés. Plus fondamentalement, la Constitution apparaît comme une règle, par nature, d’ordre public.

Une première période où les influences mêlées d’Alessandro Padoa et de Bertrand Russell s’exercent en France culmine avec les essais philosophiques de Jean Nicod. Une seconde période voit fleurir les travaux du mathématicien Jacques Herbrand ; avant de périr, il laisse son nom à un théorème fondamental. Suit une période de débats entre philosophes, mathématiciens et physiciens, stimulés en 1935 et 1937 par la tenue à Paris de deux congrès consacrés, totalement ou en partie, à la philosophie des sciences. Paulette (...) Février y esquisse une logique non classique où l’on postule l’existence de couples de propositions non composables pour ériger en principes les relations de Werner Heisenberg. Jean-Louis Destouches développe cette conception jusqu’à décrire comment édifier une théorie unifiante. La structuration des êtres mathématiques est l’objet d’études philosophiques d’Albert Lautman. Le rôle putatif de la notion de groupe en logique est interrogé. La notion de structure mathématique est l’objet de deux contributions : Marc Krasner généralise les conceptions d’Évariste Galois, attribuées à la logique et étendues à des langages infinitaires ; Nicolas Bourbaki, compte tenu de l’évolution des mathématiques, qualifie de structure ce que nous appelons aujourd’hui un modèle.

Unlike in physics, the category of thought experiment is not very common in biology. At least there are no classic examples that are as important and as well-known as the most famous thought experiments in physics, such as Galileo’s, Maxwell’s or Einstein’s. The reasons for this are far from obvious; maybe it has to do with the fact that modern biology for the most part sees itself as a thoroughly empirical discipline that engages either in real natural history or in (...) experimenting on real organisms rather than fictive ones. While theoretical biology does exist and is recognized as part of biology, its role within biology appears to be more marginal than the role of theoretical physics within physics. It could be that this marginality of theory also affects thought experiments as sources of theoretical knowledge. Of course, none of this provides a sufficient reason for thinking that thought experiments are really unimportant in biology. It is quite possible that the common perception of this matter is wrong and that there are important theoretical considerations in biology, past or present, that deserve the title of thought experiment just as much as the standard examples from physics. Some such considerations may even be widely known and considered to be important, but were not recognized as thought experiments. In fact, as we shall see, there are reasons for thinking that what is arguably the single most important biological work ever, Charles Darwin’s On the Origin of Species, contains a number of thought experiments. There are also more recent examples both in evolutionary and non-evolutionary biology, as we will show. Part of the problem in identifying positive examples in the history of biology is the lack of agreement as to what exactly a thought experiment is. Even worse, there may not be more than a family resemblance that unifies this epistemic category. We take it that classical thought experiments show the following characteristics: They serve directly or indirectly in the non-empirical epistemic evaluation of theoretical propositions, explanations or hypotheses. Thought experiments somehow appeal to the imagination. They involve hypothetical scenarios, which may or may not be fictive. In other words, thought experiments suppose that certain states of affairs hold and then try to intuit what would happen in a world where these suppositions are true. We want to examine in the following sections if there are episodes in the history of biology that satisfy these criteria. As we will show, there are a few episodes that might satisfy all three of these criteria, and many more if the imagination criterion is dropped or understood in a lose sense. In any case, this criterion is somewhat vague in the first place, unless a specific account of the imagination is presupposed. There will also be issues as to what exactly “non-empirical” means. In general, for the sake of discussion we propose to understand the term “thought experiment” here in a broad rather than a narrow sense here. We would rather be guilty of having too wide a conception of thought experiment than of missing a whole range of really interesting examples. (shrink)

In update logic as studied by Baltag, Moss, Solecki and van Benthem, little attention is paid to the interpretation of an action by an agent, which is just assumed to depend on the situation. This is actually a complex issue that nevertheless complies to some logical dynamics. In this paper, we tackle this topic. We also deal with actions that change propositional facts of the situation. In parallel, we propose a formalism to accurately represent an agent's epistemic state based on (...) hyperreal numbers. In that respect, we use infinitesimals to express what would surprise the agents (and by how much) by contradicting their beliefs. We also use a subjective probability to model the notion of belief. It turns out that our probabilistic update mechanism satisfies the AGM postulates of belief revision. (shrink)

Guillaume Lejeune | : La philosophie de Bradley se présente moins comme une tentative d’importation de la pensée allemande en Angleterre que comme une volonté de régler par le recours à divers écoles les problèmes dans lesquels la tradition empiriste se dépêtre : un atomisme de la connaissance et une conception externaliste des relations qui rendraient impossible une vision unitaire de l’expérience. La critique que développe Bradley de l’association d’idées dans la mesure où elle fait ressortir les présuppositions de (...) la tradition empiriste et en rejette le bien-fondé peut se lire comme une tentative de déconstruction de celle-ci. | : Bradley’s philosophy is not a mere attempt to import German thought in Great-Britain, but a willingness to regulate the problems in which the empiricist tradition is entangled — an atomism of knowledge and an externalist conception of relation that make impossible a unitary view of experience — by borrowing ideas from various schools. According to Bradley, associationism clearly brings out the two problematic aspects of the whole empiricism. That is why his rejection has a strategic character. It can be read as an attempt to “deconstruct” the empiricist tradition. (shrink)

This dissertation is devoted to dual-process theories, widely discussed in the recent literature in cognitive science. The author argues for a significantly modified version of the account suggested by Samuels (2009), replacing the distinction between ‘Systems’ with a distinction between ‘Types of processes,’ which allows a critique of both the (only) modularist accounts and the accounts describing a deep difference between two systems each having their specificities (functional, phenomenological and neurological). In the account of dual-process theories developed here, the distinction (...) between ‘Types of processes’ is considered, a priori, only as a heuristic distinction allowing to better understand the mind and to explain some of its properties. The main idea defended in this dissertation is that cognitive processes should be distinguished by their position in a multidimensional conceptual space allowing researchers to consider all of the characteristics and peculiarities attributed to a process, which is preferable to accounts forcing the process into either ‘System’ or either ‘Type’ identified in the most influential approaches (cf. Evans, 2008). Once this research program is in place, it will become possible to revise the concepts used and the categories defined to ground anew some of the notions we find in the literature (‘module,’ ‘System 1 / 2,’ etc.). The argument is made in three steps: -/- 1) The first chapter aims at a clarification of the notion of ‘module’ commonly used in cognitive science. Against the accounts aiming at a weakening of the notion in order to classify all of the mind’s processes as modular, the author – following most notably Faucher and Poirier (2009) and Samuels (2006) – casts doubt on how this notion is used by many influential authors, particularly in evolutionary psychology (e.g. Barrett, Carruthers, Cosmides, Tooby). -/- 2) The objective of the second chapter is to present, examine and criticize many dual-process theories and to suggest that no theory currently discussed is adequate to describe the architecture of mind. The accounts, especially influent or representative, suggested by Stanovich (1999; 2004; 2009), by Evans (2008; 2009), by Lieberman (2007; 2009) and by Carruthers (2006; 2009), are examined. -/- 3) In the third chapter, the author criticizes the framework developed by Samuels (2009) before developing his own account of dual-process theories and discussing some of its advantages.

ALl its main traits -starting with the Method of Extensiveion- are here questioned anew.

Cette étude vise à éclairer la doctrine des catégories que Wilhelm Dilthey met au service de son projet de fondation autonome des sciences de l’esprit, et notamment la manière dont elle relève son pari initial d’enraciner les catégories dans la vie sans pour autant succomber au péril du psychologisme. Nous suivons pour ce faire les principales étapes selon lesquelles cette doctrine se déploie. Elle soumet d’abord à la critique la doctrine kantienne et ses soubassements aristotéliciens : la généalogie historico-psychologique de (...) l’appareil catégorial hérité de la métaphysique à laquelle procède Dilthey met en évidence sa rupture originelle avec l’expérience. En contrepoint de telles catégories « formelles », Dilthey entend montrer la possibilité de catégories « concrètes » qui, puisées à la source même de l’expérience, sont des « catégories de la vie », soustraites aussi bien à la réduction théorique qu’au clivage du logique et de l’ontologique propres à la tradition métaphysique. Nous soulignons néanmoins la précarité qui affecte la validité de « catégories concrètes » déployées sur un plan essentiellement psychologique. Dès lors, il s’agit d’examiner comment Dilthey, se saisissant avec plus d’acuité de ce problème, tente finalement de procéder à une fondation herméneutique des « catégories de la vie », en recourant au détour de l’« expression » de l’expérience vécue et en attribuant à la signification une place centrale au sein d’un appareil catégorial entièrement renouvelé.
