Qu'est-ce qu'un enseignement? Une pensée? Qu'autorisent-ils? À la suite de Claire Brunet, Sandra Laugier et Frédérique Ildefonse qui dirigent ce volume, d'anciens étudiants, aujourd'hui chercheurs renommés ou plus discrets, creusent à travers le sillon de leur discipline ce que leur a permis l'enseignement de leur maître commune à l'École normale supérieure. Les amitiés intellectuelles s'y joignent. Ce que l'on appelle communément communication dans le monde académique devient texte. Tous, en creux, décrivent l'influence d'un enseignement, la liberté qu'il permet à des (...) esprits pour s'épanouir et nous laissent découvrir un portrait intellectuel d'une grande originalité. La pensée de Claude Imbert, philosophe, logicienne, longtemps directrice du département de philosophie de la rue d'Ulm, n'a pas les honneurs médiatiques français en sus des "académiques" d'usage. S'y prêterait-elle? Pourtant, la philosophe française est depuis plus de vingt ans lue, reçue et écoutée dans les universités du monde entier, des Etats-Unis à la Chine en passant par l'Amérique du Sud. Tous les textes rassemblés ici, comme autant de variations, sans jamais le dire, souhaitent contribuer à la reconnaissance de l'oeuvre. Un inédit "Ne rien oublier et tout apprendre" de la philosophe et un texte de Pascalle Monnier, écrivain, accompagnent le volume."--Page 4 of cover. (shrink)

There is a hint of paradox in opening this collection of texts on the procedures for totalizing knowledge in Antiquity by calling to witness the Platonic dialogues. What might they contribute, besides a critique of Sophistic polymathy, Socrates’ nescience, his way of jumping in and interrupting long discourses, the disconcerting interlude of preliminary questions, and the aporetic collapses? A host of questions does not make a book, much less a library - unless the Socratic stratagem defines some entirely new conditions, (...) or unless Plato's argument authorizes, beyond a program of study, a way of constituting knowledge with its hierarchized elements and the articulations called for by this program. A few remarks are in order here. (shrink)

: Frege's philosophical writings, including the "logistic project," acquire a new insight by being confronted with Kant's criticism and Wittgenstein's logical and grammatical investigations. Between these two points a non-formalist history of logic is just taking shape, a history emphasizing the Greek and Kantian inheritance and its aftermath. It allows us to understand the radical change in rationality introduced by Gottlob Frege's syntax. This syntax put an end to Greek categorization and opened the way to the multiplicity of expressions producing (...) their own intelligibility. This article is based on more technical analyses of Frege which Claude Imbert has previously offered in other writings (see references). (shrink)

Kant prit pour pivot de la révolution copernicienne l'immutabilité d'une table qui portait toute l'autorité du classicisme et révélait les opérations secrètes d'un sensus communis logicus. La logique n'avait pas d'histoire. Après la rupture introduite par la logique mathématique et pour la conjurer, on s'est intéressé à son histoire comme présentant autant de variétés d'une même forme. Mais la forme, terme homonyme entre l'eidos platonicien et la syntaxe moderne, gardait l'écorce sans le fruit, oubliant que l'héritage grec avait fructifié ailleurs, (...) dans les arts et dans les sciences et vivait précisément de ses métamorphoses. Le projet de Platon, accompli par le stoïcisme, donne la mesure de l'héritage athénien. L'épisode ouvert par Frege laissait un tout autre avenir que de choisir entre la formalisation ou le silence. Car la logique mathématique, liée à l'histoire de l'algèbre et de la calculabilité, ménageait la place pour une activité philosophique délivrée à son tour des opérations obscures du sens commun et consciente de ses symbolismes. Ce qui redonne sens aux réformes de l'entendement, opération philosophique essentielle et constante, contre les méthodes supposées régir toutes les manières de la connaissance. Cette autre histoire se trame de Port-Royal, à d'Alembert, Wittgenstein, Cavaillès et Merleau-Ponty. La connaissance s'y trouve servie par la diversité de ses supports, y compris styles et syntaxes, tous inscrits sur le palimpseste des opérations inconscientes qui précèdent toute épistémologie.

Résumé : Chez Baudelaire il y a une expérience moderne comme une pleine et égale possession de principe, comme une revanche mentale sur la diversité souvent scandaleuse des évènements et des conditions de la vie. Et si le moderne met en jeu nos proximités sensorielles et cérébrales, varie nos cartes corporelles, il n’en finira jamais . Ici s’éclaire cette physiologie insolite de la vie moderne – ce trope de Baudelaire serait la réponse , la plus exacte jusque dans son assonance, (...) donnée au corbeau de Poe , à ses mots volés on ne sait où et psalmodiés par un perroquet noir - never more . Mot-Clès: Littérature. Language. Esthétique. (shrink)

This article proposes a reading of the work of Claude Imbert through the concept of participation. This concept comes from the logical tradition of Plato, in which it designates the inscription of the intelligible within the sensible. But Imbert, following the Stoics, gives it an anthropological turn, showing that it opens onto a reading of the syntaxes by which an event is correlated to another. This turn can be considered as a continuation of the genealogy going from (...) Lévy-Bruhl to Lévi-Strauss in the anthropological reflection on the participation of the intelligible and the sensible.

Claude Imbert often declares that the activity of philosophy now needs to be in line with the teachings of anthropology. In her book Maurice Merleau-Ponty, the very fact that the last course of the author of Phenomenology of Perception, questioning ‘The Possibility of Philosophy’, sketched out ‘the anthropological outline of an intellectual activity unburdened by any a priori’ [les contours anthropologiques d'un activité intellectuelle délestée de tout a priori] is considered by her as more evidence for such a (...) necessity. My contribution explores the meaning of Claude Imbert's affirmation that today the possibility of philosophy is deeply connected with anthropological knowledge. It will, in particular, confront such an affirmation with the debate among African philosophers, concerning the relationship between philosophical activity and ethnography. (shrink)

Convinced that logic has a history and that its history always manages to surprise the philosophers, Claude Imbert has devoted much of her work to the study of the Stoic school and of the late-nineteenth-century German logician Gottlob Frege. In the fifth chapter of her book Pour une histoire de la logique, she examines the trajectory of Frege's awareness of what his new logic entails, in particular the way it subverts the project of Kant.

Tolkien is one of our most beloved fantasy writers. Such was the power of his imagination that much has been written on his invented world, languages, and myth. This book is an invitation to tread the paths of Tolkien's realm, exploring three regions of his work: language, myth, and imagination. We will be looking for a path leading to a summit from where we can view Tolkien's whole realm. Yannick Imbert argues that we can gain such a view only (...) if we understand Tolkien's philosophical theology, his Thomism. To attain this vantage point and better understand the genius of his Middle Earth, readers journey with Tolkien through his academic, personal, and theological milieu, which together formed his Thomistic imagination."--Amazon.

Experiments (E), computer simulations (CS) and thought experiments (TE) are usually seen as playing different roles in science and as having different epistemologies. Accordingly, they are usually analyzed separately. We argue in this paper that these activities can contribute to answering the same questions by playing the same epistemic role when they are used to unfold the content of a well-described scenario. We emphasize that in such cases, these three activities can be described by means of the same conceptual framework—even (...) if each of them, because they involve different types of processes, fall under these concepts in different ways. We further illustrate our claims by presenting a threefold case study describing how a TE, a CS and an E were indeed used in the same role at different periods to answer the same questions about the possibility of a physical Maxwellian demon. We also point at fluid dynamics as another field where these activities seem to be playing the same unfolding role. We analyze the importance of unfolding as a general task of science and highlight how our description in terms of epistemic functions articulates in a noncommittal way with the epistemology of these three activities and accounts for their similarities and the existence of hybrid forms of activities. We finally emphasize that picturing these activities as functionally substitutable does not imply that they are epistemologically substitutable. (shrink)

Whereas computer simulations involve no direct physical interaction between the machine they are run on and the physical systems they are used to investigate, they are often used as experiments and yield data about these systems. It is commonly argued that they do so because they are implemented on physical machines. We claim that physicality is not necessary for their representational and predictive capacities and that the explanation of why computer simulations generate desired information about their target system is only (...) to be found in the detailed analysis of their semantic levels. We provide such an analysis and we determine the actual consequences of physical implementation for simulations. (shrink)

Epistemic accounts of scientific collaboration usually assume that, one way or another, two heads really are more than twice better than one. We show that this hypothesis is unduly strong. We present a deliberately crude model with unfavorable hypotheses. We show that, even then, when the priority rule is applied, large differences in successfulness can emerge from small differences in efficiency, with sometimes increasing marginal returns. We emphasize that success is sensitive to the structure of competing communities. Our results suggest (...) that purely epistemic explanations of the efficiency of collaborations are less plausible but have much more powerful socioepistemic versions. (shrink)

L'Odyssée, le plus ancien poème de la culture occidentale, met en scène la métamorphose qui change Ulysse en lui-même sous les yeux dessillés de ceux qui échouaient jusque-là à le reconnaître. Ulysse constitue ainsi la première d'une longue série de figures donnant corps à cette opération mystérieuse : le passage de l'existence en régime d'obscurité à l'existence "en personne", dans une forme de vérité. Que signifie un tel passage? Comment s'opère cette transition? Quelles formes cette idée d'existence en personne a-t-elle (...) pu revêtir dans la pensée occidentale? Claude Romano interroge les sources, y compris lointaines, de cette idée d' "existence en vérité" telle qu'elle sous-tend notamment l'idéal moderne d'authenticité personnelle, en retraçant la généalogie de cet idéal et en exhumant certaines de ses formes plus anciennes. Chemin faisant, le lecteur découvre différents types et régimes de discours, philosophique, mais aussi théologique, spirituel, rhétorique, littéraire, esthétique. Romano esquisse ainsi une histoire de la philosophie occidentale aux contours bien différents de ceux qu'on lui prête généralement : à l'écart des grandes métaphysiques du moi et de la subjectivité, il emprunte les chemins de traverse d'une enquête sur les formes de vie et les modes d'existence.

Novel forms of matter, such as states made of gluons (glueballs), multiquark mesons or baryons and hybrid mesons are predicted by low energy QCD, for which several candidates have recently been identified. Searching for such exotic states of matter and studying their production and decay properties in detail has become a flourishing field at the experimental facilities now available or being built - e.g. BESIII in Beijing, BELLE II at SuperKEKB, GlueX at Jefferson Lab, PANDA at FAIR, J-PARC and in (...) the upgraded LHC experiments, in particular LHCb. A modern primer in the field is required so as to both revive and update the teaching of a new generation of researchers in the field of QCD. These lectures on hadron spectroscopy are intended for Master and PhD students and have been originally developed for a course delivered at the Stefan Meyer Institute of the Austrian Academy of Sciences. They are phenomenologically oriented and intended as complementary material for basic courses in particle and nuclear physics. The book describes the spectra of light and heavy mesons and baryons, and introduces the fundamental properties based on symmetries. Further, it derives multiplet structures, mixing angle, decay coupling constants, magnetic moments of baryons, and predictions for multiquark states and compares these with suitable experimental data. Basic methods of calculating decay angular distributions and determining masses and widths of resonances are also presented. The appendices provide students and newcomers to the field with the necessary background information, and include a set of problems and solutions. (shrink)

On connaît de Charles Larmore (1950), philosophe moral américain contemporain, ses célèbres objections à John Rawls, mais peu de travaux se concentrent sur sa philosophie : son réalisme moral, sa réhabilitation partielle de l'idéal d'authenticité, sa version du libéralisme politique ou encore à sa théorie normativiste du moi. Ce sont ces différents aspects de sa pensée que les études contenues dans ce volume, premier ouvrage entièrement consacré à l'oeuvre de Charles Larmore, interrogent et mettent en perspective. Un essai inédit du (...) philosophe américain ainsi qu'un débat entre Charles Larmore et Alain Renaut autour de la controverse réalisme-idéalisme y figurent également, en guise de conclusion.

"Alexis de Tocqueville compte parmi le petit nombre de penseurs dont la réputation ne fait que s’affirmer avec le temps. Depuis la parution de sa Démocratie en Amérique, il y a près de deux siècles, des études innombrables ont souligné la justesse et la perspicacité de sa vision de l’histoire moderne. Dans ce livre, Claude Corbo met en lumière des aspects moins connus de l’homme et de l’œuvre, qu’il connaît de longue date. Au cours de son célèbre voyage de (...) 1831-1832, Tocqueville rencontre non seulement des citoyens de la jeune république américaine, mais aussi ceux qui ont pris figure de vaincus. Il prend le temps d’observer les Autochtones aussi bien en périphérie des villes qu’aux confins que constitue la Frontière. Du 23 août au 2 septembre 1831, visitant Montréal, Québec et les campagnes environnantes, il fait avec ravissement la connaissance des Canadiens français du Bas-Canada. Dans les deux cas, ses rencontres et ses observations lui inspirent des réflexions lucides et sombres à la fois. Des nations autochtones, il écrit sans ménagements: "La ruine de ces peuples a commencé du jour où les Européens ont abordé sur leurs rivages; elle a toujours continué depuis; elle achève de s’opérer de nos jours." Des Canadiens français, il se désole d’avouer que "ce ne sera jamais un peuple nombreux. Tout deviendra anglais autour de lui.""--Page 4 de la couverture. (shrink)

Up until today, the term linguistics has never figured in the title of any chair in the Collège de France. However, those having a rapport with language have not been lacking, among them those of “language and literature,” “history and philology” of various cultures, philology, although it does not study language itself, having recourse to it. There are four personalities to be kept in mind in the twentieth century: Abbé Rousselot, whose teaching of phonetics, although briefly, left a permanent mark (...) on his listeners; Mario Roques, who gave a course in the “Histoire du vocabulaire français” from 1937 to 1946; Roland Barthes, who rendered “Sémiologie littéraire” illustrious from 1976 to 1980; and M. Zemb, who two years ago was the first linguist in the modern sense to enter the Collège, with a chair of “Grammaire et pensée allemandes.”. (shrink)

The persistent pervasiveness of inappropriately small studies in empirical fields is regu-larly deplored in scientific discussions. Consensually, taken individually, higher-powered studies are more likely to be truth-conducive. However, are they also beneficial for the wider performance of truth-seeking communities? We study the impact of sample sizes on collective exploration dynamics under ordinary conditions of resource limita-tion. We find that large collaborative studies, because they decrease diversity, can have detrimental effects in certain realistic circumstances that we characterize precisely. We show how (...) limited inertia mechanisms may partially solve this pooling dilemma and dis-cuss our findings briefly in terms of editorial policies. (shrink)
