In this paper, we examine Sextus Empiricus' treatise Against the geometers . We first set this treatise in the overall context of the sceptic's polemics against the liberal arts. After a discussion of Sextus' attitude to the quadrivium , we discuss the structure, the sources and the target of the Against the geometers . It appears that Euclid is not Sextus' source, and neither he, nor the professional geometers, seem to be Sextus' main targets. Of course, Sextus never really makes (...) clear his precise target, but his attacks are rather directed against geometry as a means of modelling the physical world, thus ruining the support geometry was intended to bring to the physical part of dogmatic philosophy.

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.

Galileo asked in his Dialogue of the Two New Sciences what relationship exists between the size of the set of all natural numbers and the size of the set of all square natural numbers. Although one is a proper subset of the other, suggesting that there are strictly fewer squares than natural numbers, the existence of a simple one-to-one correspondence between the two sets suggests that they have, in fact, the same size. Cantor famously based the modern notion of cardinality (...) on the second intuition, but recent advances in mathematical logic (most notably, numerosity theory) have renewed an interest in the question whether Cantor’s way out of Galileo’s paradox was the only possible one. I present a new solution to Galileo’s paradox and argue that it is a better alternative to the Cantorian solution than numerosity theory. In fact, I argue that it is the best possible way out of Galileo's Paradox that can be based on the "Euclidean" intuition that the whole is always greater than any of its proper parts. (shrink)

This conference was devoted to the 80 years of the Copenhagen Interpretation, and to the question of the relevance of the Copenhagen interpretation for the present understanding of quantum mechanics. It is in this framework that fundamental questions raised by quantum mechanics, especially in information theory, were discussed throughout the conference. As has become customary in our series of conference in Växjö, we were glad to welcome a fruitful assembly of theoretical physicists, experimentalists, mathematicians and even philosophers interested in the (...) foundations of probability and physics. The nature of quantum fluctuations---in the form of Stochastic Electrodynamics or in other approaches to stochastic quantum mechanics---was also a central topic discussed during the conference, especially during debates. We should also mention talks on the completeness or incompleteness of quantum mechanics; on macroscopic quantum systems; on Bell's inequality, entanglement and experiments on quantum nonlocality (and locality); on Bohmian mechanics; on the connection between quantum mechanics and general relativity; on quantum probability; on quantum computing, quantum teleportation and quantum cryptography technologies; and more generally on the mathematical formalism of quantum mechanics and on the philosophical problems raised by its interpretations.

Le film n’est pas seulement un récit, c’est aussi un discours sur le monde. Or, trop souvent, la puissance de ce discours est surestimée et les publics caricaturés, en contradiction avec notre pratique ordinaire d’une discussion, non seulement après, mais avec les films. La tradition rhétorique et argumentative, retravaillée aujourd’hui dans une perspective pragmatique, envisage formes et contextes conjointement et permet de comprendre les liens entre le film, son discours et le spectateur. Entre formes et espace public, les analyses de (...) films, reportages et séries proposées dans cet ouvrage montrent ainsi que la démarche rhétorique permet de restituer, à côté de leur capacité mimétique, la capacité délibérative des images et des sons, fondement d’un dialogue entre le film et le spectateur.

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.

_A portrait of Martin Heidegger as a man and a philosopher_ In this biography of Martin Heidegger (1889–1976), now available in English, historian Guillaume Payen synthesizes the connections between the German philosopher’s life and work. Critically, but without polemics, he creates a portrait of Heidegger in his time, using all available sources—lectures, letters, and the notorious “black notebooks.” Payen chronicles Heidegger’s “changing destinies”: after the First World War, an uncompromising Catholicism gave way to a vigorous striving for a philosophical (...) revolution—fertile ground for National Socialism. The book reflects a life of light and shadow. Heidegger was a great philosopher and teacher who cultivated friendships and love affairs with Jews but also was an anti-Semitic nationalist who lamented the “Judaization of German intellectual life.”.

How do we individuate the senses, what exactly do we do when we do so, and why does it matter? In the following article, I propose a general answer to these related questions based on Franz Brentano's views on the senses. After a short survey of various answers offered in the recent literature on the senses, I distinguish between two major ways of answering this question, causally and descriptively, arguing that only answers giving priority to description and to the classification (...) involved in it are on the right track for a general answer to the related questions. In the second part of the article, I argue that Brentano's descriptive psychology is an attractive candidate for such an answer. His descriptive psychology provides a plausible account of the classification involved in description, in particular regarding the classification of sensory qualities. I close the article by briefly explaining how Brentano spells out the priority of descriptive answers over causal ones. (shrink)

En 2021, le livre de Van Rensselaer Potter intitulé Bioethics: Bridge to the Future a célébré son cinquantième anniversaire de parution. Or, la conception de la bioéthique proposée par l’auteur diffère de celle d’André Hellegers, qui a fait école. Pourtant, conçu comme guide, Potter y présente des éléments importants pour penser la place de la bioéthique dans le contexte sociétal et le développement actuelle des connaissances. Dans le texte qui suit, nous abordons certains éléments du contexte dans lequel ce livre (...) a pris forme. Nous nous arrêterons brièvement pour décrire la perspective dominante de la bioéthique. Puis, nous ferons ressortir certains éléments importants de la conception qu’a l’auteur de ce que devrait être la bioéthique. Nous terminerons en examinant les répercussions de cette pensée dans deux dossiers : celui de l’université et celui du développement durable dans sa perspective onusienne. Cette démarche nous conduira vers un élément que nous considérons important de la pensée de l’auteur, celui de l’ouverture. Ouverture qui est offerte à la bioéthique par l’inclusion de perspectives ayant cours quant aux compréhensions variées du vivant, ouverture à la considération des savoirs ancestraux et des savoirs communs, ouverture aussi à tout autre contexte, qu’ils impliquent des situations minoritaires, des personnes défavorisées ou autres. Cette ouverture donne un sens particulier à une valeur primordiale de la bioéthique, celle du respect de la dignité humaine. (shrink)

On se souvient que Les Mots et les Choses s’ouvrait sur l’inextinguible rire secouant les « familiarités de [notre] pensée », à la lecture d’un texte de Borges. On se souvient de la jubilation de Foucault à citer cette incertaine « encyclopédie chinoise », de l’attelage, mystérieux et apocryphe, formé par l’énumération de ces catégories des antipodes, de l’inquiétude indicible suscitée par leur simple juxtaposition syntaxique : Les animaux se divisent en : a) appartenant à l’Empereur, b) emb...

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)

Au Roland Barthes critique, celui des analyses litteraires des Essais critiques, du Sur Racine ou des constructions theoriques nourries par la linguistique et le structuralisme comme le Degre zero de l ecriture, S/Z, le Systeme de la mode; au Roland Barthes ecrivain, sachant meler, avec une originalite inimitable, fiction et reflexions analytiques dans le Roland Barthes par Roland Barthes ou les Fragments d un discours amoureux, il faudrait ajouter un Roland Barthes, moins connu et moins analyse, celui de l - (...) amateur - d art. Il n aura pas fallu attendre son dernier livre, La Chambre claire, pour savoir que Roland Barthes aimait les uvres d art visuel et qu il pratiquait lui-meme, avec grand plaisir et serieux, la peinture. Des ses premiers textes rassembles dans les Essais critiques, il associe a des etudes sur Tacite, Chateaubriand, Baudelaire ou Robbe-Grillet, un essai sur Pieter Saenredam avec lequel il ouvre un recueil pourtant consacre a la litterature. Tout au long de son uvre, que cela soit sous la forme de preface de catalogues consacres a des artistes contemporains (Bernard Requichot, Daniel Boudinet, Cy Twombly), d articles sur des artistes classiques (Arcimboldo, Artemisia Gentileschi) ou de reflexions plus generales sur l art (le kitsch, le cinema, l abstraction, la musique), Roland Barthes a accorde une attention toute particuliere aux images. Elles etaient, a ses yeux, bien plus qu un passe-temps, un delassement intellectuel qui l eloignait de son veritable travail critique. L image, et l imaginaire qui lui est lie, possede une vertu que le texte ne semble pas pouvoir revendiquer: meler le langage expressif au discours critique, faire emerger la - substance sous le concept - et pousser la question de la signification jusqu a sa limite la plus extreme. Sans s embarrasser des regles methodiques dictees par l histoire de l art, en se voulant - sauvage et sans culture - devant ces uvres d art qui venaient a lui comme par - inadvertance -, qui l incitaient a l - aventure -, Roland Barthes a elabore une - esthetique - qui demeure une des plus singulieres et utiles contributions a l etude des images. Le - troisieme sens - et son correlat, la - signifiance - (cet - au-dela - du sens), l - imaginaire de l image - ou bien encore le celebre couple Punctum/ Studium avec lequel il precise la dimension subjective de tout commerce avec les uvres sont autant de propositions methodiques que l auteur reconsidere attentivement afin de tirer toute la force heuristique de cette - lecon de l image - a laquelle nous convie Roland Barthes. La - lecon de l art - que Barthes retient de son commerce constant avec les uvres d artistes contemporains (Cy Twombly, Daniel Boudinet, Bernard Requichot) ou anciens (Saenredam, Arcimboldo) a permis de developper une reflexion singuliere sur le fonctionnement des images. - En elaborant des notions comme la - signifiance -, le - troisieme sens - ou le fameux - punctum - afin de traduire les effets que les images provoquaient sur lui, Barthes a compose une veritable esthetique qu il est temps de lire avec autant de serieux que de plaisir.".

Le manuel de sophismes politiques de Bentham se fixait pour objectif de dénoncer un certain nombre de raisonnements fallacieux destinés à entraver les propositions de réforme politique.

Although Wilhelm Dilthey and Franz Brentano apparently were pursuing roughly the same objective—to offer a description of our mental functions and of their relations to objects—and both called their respective research programs ‘descriptive psychology’, they seem to have used the term to refer to two different methods of psychological research. In this article, I compare analyses of these differences. Against the reading of Orth but also against a possible application of recent relativist accounts of the epistemology of peer disagreement to (...) this case, I argue that their apparent shared objective is not enough to support an understanding of their views as two alternatives within a given historical or scientific context, or as a mutual peer disagreement. I show that the impression of a shared objective can be explained away as stemming from the influence of their teacher Adolf Trendelenburg, and I stress that the case of introspection strongly suggests that an account in terms of peer disagreement is not plausible. Finally, I conclude that the opposition between two traditions, Austrian philosophy and historicism, might be better suited to account for the dispute and its apparent common historical context.

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.

This paper examines the “critique of historical existence” as a main theme in Karl Löwith’s philosophical works and discusses its emergence, its exact meaning and its contemporary relevance. First, the study shows that Löwith’s critique of History stems from his preoccupation with the question of nihilism. He first discusses the question of “the world as such” in the 1920’s in the context of his anthropological project, and then again in the 1930’s as part of his interpretation of the work of (...) Nietzsche. Secondly, a distinction is proposed between, on the one hand, Löwith’s investigation into the “theological background of the philosophy of history” and, on the other hand, his radical criticism of history as a “historical world”. Finally, the paper sheds light on the difficulties that challenge the project of overcoming the modern historical paradigm, and goes on to discuss the new relevance that Löwith’s philosophy could have today in order to think anew the relationship between nature and history.

Alf Ross je želel izoblikovati »pristno« realistično teorijo prava. To pomeni, da naj bi bila ta sposobna po eni strani razrešiti probleme, s katerimi sta se soočali tako Kelsnova normativistična teorija kot teorija ameriških realistov, po drugi strani pa poustvariti njihove razprave na znanstveni način. Rossova izvirnost tiči v njegovem pojmu pristojnostnih norm, ki jih je pred vsemi drugimi obravnaval kot »konstitutivna pravila«. V nasprotju s trditvami mnogih komentatorjev takšen pojem konstitutivnih norm ni neskladen z Rossovo realistično teorijo prava. V (...) luči njegovih zgodnjih zapisov je mogoče kompetenčne norme razumeti kot racionalizacije, ki lahko izrazijo nagnjenost naslovnikov norm, da določena dejstva prepoznajo kot pravo.

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)

The Grand Challenges literature brings under its umbrella a wide variety of disjointed phenomena but runs the risk of reinventing the wheel as well as overlooking incremental progress and past work. To avert this, scholars need to (dis)connect (dis)similar issues, build on past research on these issues, and create opportunities for generalizability through theoretical examinations.

Why did Thomas More write two versions of his History of King Richard III, one in English and the other in Latin? Critics tend to answer this question by arguing that the two versions were not destined for the same audience: the Latin for a continental elite, the vernacular for a larger British readership. Although perfectly convincing, this explanation may not be the only one: this paper tries to underline the existence of another motivation, one of a literary nature. The (...) History of King Richard III indeed combines two historiographical models: the ancient and classical monograph as illustrated by Sallust, and the medieval tradition of the chronicle. The oscillation between English and Latin may reflect More's wish to renovate the genre of the medieval chronicle, accomplished by an hybridization with classical Latin models—as if More attempted to grasp the best of both traditions in order to initiate a new means of writing history.
