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.

In this paper, I investigate how Xenophanes was ‘eleaticised’, i.e. attributed theses and arguments that belong to Parmenides and Melissus. I examine texts of Plato, Aristotle and Theophrastus in order to determine if they considered Xenophanes as a philosopher and a monist. I show that neither Plato nor Aristotle regarded him as a philosopher, but rather as a pantheist poet who claimed, in a vague way, that everything is one. But Theophrastus interpreted too literally Aristotle’s claims and was the first (...) to make Xenophanes a proper monist philosopher. (shrink)

Melissus’ fragment B9, where he claims that being has no body and no thickness, raises the question of how being can be extended and full and at the same time incorporeal. Most recent interpretations tried to avoid lending to “body” the meaning of “physical body”. My aim in this paper is to reconstruct Melissus’ notion of body, by examining its connection to “thickness”. I show that Melissus meant by “thick” something that has distinct parts and therefore supports in B9 the (...) indivisibility of being. I then indicate that he relied on the contrast between soul and body for his conception of corporeality, by highlighting that by Presocratic thinkers, the soul was considered as “thin” and regarded as something that could be exempt of the division into parts. I conclude that even though Melissus’ notion of incorporeality is very different from the one Plato will develop, he made a huge step toward its conceptualization. (shrink)

This paper examines two doxographies present in Ḥunayn’s summaries to Galen’s treatise On the Elements. We track the origin of these doxographies back, from Greek scolia to Galen’s treatise to Simplicius’ Commentary on Aristotle’s Physics, which we show to be the ultimate source. We also point out that Simplicius’ Commentary inspired an interpretation of Parmenides and Melissus that we find in Ḥunayn’s texts. This allows us to see remnants of Simplicius’ Commentary in the Arabic world and to shed some light (...) on the production of these summaries to Galen’s work called Summaria Alexandrinorum.

Cet ouvrage collectif, issu de la conférence Eleatica qui a eu lieu du 15 au 18 avril 2012 à Ascea, est construit autour des trois présentations données par Jaap Mansfeld à cette occasion, intitulées « Melissus between Miletus and Elea ». Elles sont précédées d’une introduction de Massimo Pulpito, et suivies d’un ensemble de 9 courts articles (de 5 à 10 pages) qui constituent des réponses à divers points de l’intervention de Mansfeld ; enfin, Jaap Mansfeld a l’occasion de répondre (...) en quelques...

Jaap Mansfeld (M.) a rassemblé dans ce livre dix-neuf articles, parmi lesquels une (longue) recension, qui portent tous sur les penseurs préplatoniciens et leur interprétation. La plupart des travaux sélectionnés sont récents, puisqu’à l’exception de deux d’entre eux, ils ont tous été publiés après 2004. Ils sont reproduits avec la pagination d’origine indiquée en marge et peu de modifications : une partie du chapitre 19 a été enlevée pour éviter des redondances avec le chapitre 3, et des add...

Cet article examine l’influence sur la première hypothèse du Parménide de deux penseurs dont l’importance a été négligée par les critiques : Mélissos et Gorgias. Après avoir observé que les prédicats attribués à l’un ainsi que la forme démonstrative sont plus représentatifs de l’éléatisme de Mélissos que de celui de Parménide, nous expliquons ce constat par le fait que Platon reprenne une partie du Traité du Non-être de Gorgias qui vise elle-même essentiellement Mélissos. Nous démontrons alors que la première hypothèse, (...) et même l’ensemble de la seconde partie du Parménide, est un pastiche du Traité du Non-être, et nous en tirons des conclusions sur le statut de l’exercice dialectique mis en œuvre dans le Parménide.

Both Hippolytus of Rome and Sextus Empiricus attribute a concept of λόγος to Empedocles, relying on fragments that seem to have nothing to do with this claim. This article aims to show how the identification and clarification of their common Stoic source helps us to understand these texts better, and to reconstruct an interpretation of Empedocles’ epistemology that has not attracted critical attention so far.

Claude Romano seeks to change all that, to describe precisely what sort of phenomenon an event is and to establish how it can be grasped via a phenomenology.

ArgumentAfter having measured the velocity of the nervous impulse in the 1850s, Helmholtz began doing research on the temporal dimensions of visual perception. Experiments dealing with the velocity of propagation in nerves were carried out occasionally for some fifteen years until their final publication in 1871. Although the temporal dimension of perception seems to have interested Helmholtz less than problems of geometry and space, his experiments on the time of perception were technically rather subtle and seminal, especially compared with experiments (...) performed by his contemporaries, such as Sigmund Exner, William James, Rudolf Hermann Lotze, Ernst Mach, Wilhelm Volkmann, and Wilhelm Wundt. Helmholtz’s conception of the temporal aspects of perception reflects the continuity that holds between psychophysiological research and the Kantian philosophical background. (shrink)

In the latest years of the 6th/12th century, two chains of affiliation of a distinctive kind make their appearance in the Muslim world, in the East on one hand, and in the West on the other: the first is referred to in the sources as silsilat al-muṣāfaḥa, the second as silsilat al-mushābaka. These ‘chains’, mentioned mostly in works pertaining to the genre of prosopographic literature in the largest sense, experienced a broad and rapid expansion throughout the dār al-islām. They are (...) linked to a specific ritual aimed at perpetuating, across generations, a physical contact with the Prophet. Widespread among the ʿulamāʾ, they become conflated with the musalsalāt ḥadīths, or ‘chained traditions’, during the Ottoman era. (shrink)

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)
