C’est la première édition critique du Liber particularis de Michel Scot, traité cosmologique latin qui constitue la deuxième partie de son Liber introductorius, rédigé entre 1220 et 1235 environ. L’édition est effectuée sur la base du ms. Bodl. Canon. Misc. 555 (collationné avec les mss Vatican, BAV Rossi IX 11 et Milan, Ambrosiana L 92 Sup), afin de restituer une version qui circula, sous une forme relativement stable, en Italie dans la première moitié du xiv e siècle. Dans (...) l’introduction, on trouvera les données essentielles sur les manuscrits du Liber particularis, sur la place de ce traité dans l’œuvre de Michel Scot et dans le contexte intellectuel de la cour de Frédéric II, ainsi qu’un essai préliminaire visant à l’inscrire dans le développement des savoirs en Occident dans la première moitié du xiii e siècle.

The authorship of the Theorica planterum has been controversial. According to a medieval tradition, the work was written by Gerard of Cremona. In the scholarly literature , however, the work was attributed to Gerard of Sabbioneta. This note reassesses the evidence put forward in support of the authorship of Gerard of Sabbioneta and argues, on the basis of manuscript evidence, that it is highly likely that the Theorica planetarum was translated by Gerard of Cremona or someone from his circle.

Cet ouvrage confronte la conception des principes constitutifs de la réalité chez Thomas d'Aquin, Scot, Occam et quelques conséquences produites par ces principes. Il met ainsi en lumière trois modèles de philosophie pertinents pour éclairer la pensée contemporaine : une philosophie transcendantale, une pensée nominaliste empiriste et une pensée de l'acte d'être de l'être en acte. Aux yeux de l'auteur, cette dernière possède, grâce à l'ordre hiérarchique, à la causalité et à l'analogie, la vertu d'échapper aux contradictions et aux (...) réductions qui menacent les deux premières. Un tel débat montre l'intérêt permanent d'une ontologie de l'acte. (shrink)

Francis Bertin s’est fait connaître dans le milieu des historiens du néoplatonisme latin notamment par quelques traductions: celle de trois petits traités de Nicolas de Cues et celle du Peri physeon de Jean Scot Erigène, dont deux volumes seulement ont paru jusqu’ici. Il nous propose avec le présent volume la traduction de cinq sermons prononcés par Nicolas de Cues: le sermon Dies sanctificatus du 25 décembre 1439, le sermon Verbum caro factum estI du 27 décembre 1453, le sermon homonyme (...) Verbum caro factum est II du 1er janvier 1454, celui qui est intitulé Ubi est qui natus est du 6 janvier 1456 et enfin le Tota pulchra es, amica mea du 8 septembre 1456. (shrink)

Le but de cet article est de contribuer au débat sur la relation entre les pratiques prédictives et l’orthodoxie religieuse, telle qu’elle est exposée dans le Liber introductorius de Michel Scot. Au cœur de ce travail se trouve l’étude de la discussion de l’interprétation des signes inhabituels et des événements inattendus par Michel Scot, à la fois dans le Liber quatuor distinctionum et le Liber particularis. L’analyse de nouvelles preuves textuelles, jusque là passées inaperçues, permettra par (...) ailleurs la réévaluation de la réception de Michel Scot en tant qu’autorité dans le domaine des pratiques prédictives.

ABSTRACT: In the 18th century, Kant evaluated that his historical period was not a time of enlightenment, but rather minority, because of man’s inability to use his own understanding. Adorno updated this problem, interpreting the minority in our presente in terms of loss of experience. Men are no longer apt to experience, because the technical and economic apparatus prevents the clarification and awareness of reality. From this diagnosis, The aim of this article is to investigate Adorno’s educational thought in its (...) possibilities of emancipation. In our point of view, the role of education, in the thoughts of the Frankfurtian, is to recover the critical autonomy of individuals, through dialectical thinking, to rebuild the damaged experience.

This book provides an innovative way to revisit the depth and scope of our moral/post-moral worldviews, while undertaking an ontic reflection about organizational life. The ontic dimension of life refers to existing entities’ lived experiences. It has nothing to do with psychological and relational processes. The ontic level of analysis mirrors a philosophical outlook on organizational life. Unlike moral worldviews, post-moral worldviews oppose the existence of Truth-itself. Post-moral worldviews rather imply that dialogical relationships allow people to express their own truth-claims (...) and welcome others’ truth-claims. The purpose of this book is to explain the philosophical implications of moral and post-moral worldviews and the way to move from a moral to a post-moral worldview. Moreover, this book explores the possibility to transcend the moral/post-moral dualism, through moral deliberation processes and a reinterpretation of the Presence of the Infinite in all dimensions of human life. This book could eventually help to better grasp the basic philosophical challenges behind ethical reflection about organizational issues. (shrink)

On désigne ici comme « espace esthétique » la forme subjective et pure de l’intuition du sens externe, telle que la met à jour l’exposition métaphysique de l’espace. Kant l’appelle ainsi « espace métaphysique » en l’opposant rigoureusement à l’« espace géométrique », déjà conceptualisé et ne relevant plus comme tel de l’Esthétique transcendantale dans son moment originaire. L’espace esthétique doit pouvoir être atteint dans son essence pure avant et indépendamment de ce que la « mathématique de l’étendue » constitue (...) du second : il faut délier le moment propre de l’Esthétique de toute subordination à la géométrie. À l’inverse, on esquissera la genèse transcendantale des différents types d’objectivité géométrique désignés dans des « concepts d’espace » (le quantum, la figure, l’espace lui-même considéré objectivement).

Etrange parcours que celui du Logos qui, de Heraclite a nos jours, tend a s'effacer, dans ce monde actuel, tout entier voue a la science, au tout numerique. Cette vision heracliteenne de la totalite s'est estompee, transformee qu'elle fut deja des les premiers siecles de notre ere dans sa postulation religieuse, puis dans la modernite, et s'est perdue dans un monde ou, science et technique prenant leur envol, l'homme avait comme horizon de " devenir comme maitre et possesseur de la (...)

Michel Blay analyse cet etat qui nous laisse de plus en plus en desherence ; et dans un monde ou " Dieu est mort, et c'est nous qui l'avons tue ", comment ne pas sombrer dans cette illusion d'un homme tout-puissant, dans lequel meme le psychique est traite a l'aune des neuro-sciences ou l'homme a perdu sa completude et ne pense meme plus a la chercher?

Although many small businesses and a great number of large enterprises have environmental policies, the contents of such policies vary widely according to their emphases either on technical rationality and technocentrism/technocracy or on ecological rationality and ecocentrism/ecocracy. I present them in four categories: with regard to strong anthropocentrism, (1) the neo-technocratic enterprise and (2) the techno-environmentalist enterprise; and with regard to weak anthropocentrism, (3) the pseudo-environmentalist enterprise and (4) the quasi-environmentalist enterprise. Such a typology can be useful for business managers (...) to write and/or review their environmental policies. However, it only reflects the “ideal values” of the enterprise, not the corporate story with regard to environmental issues. (shrink)

It is commonly thought that authors can make anything whatsoever true in their fictions by artistic fiat. Harry Deutsch originally called this position the Principle of Poetic License. If true, PPL sets an important constraint on accounts of fictional truth: they must be such as to allow that, for any x, one can write a story in which it is true that x. I argue that PPL is far too strong: it requires us to abandon the law of non-contradiction and (...) entails a radical revision of otherwise ordinary commitments about truth in fiction. (shrink)

Les Études philosophiques est une revue publiée par les Presses universitaires de France. Fondée en 1926 par Gaston Berger et d’abord publiée à Marseille, la revue fut initialement le Bulletin d’une société philosophique régionale. Il s’agissait de rendre compte des travaux locaux tout en assurant la communication des orientations et des résultats de la recherche au plan international. La revue s’est attachée à maintenir cette double vocation, ancrage dans la tradition philosophique et ouverture sur l’actualité de la philosophie en train (...) de se faire. Elle est un lieu d’élaboration et d’échange de la recherche philosophique ; elle donne un état de la recherche française et internationale, en publiant des études d’histoire de la philosophique mais aussi bien des articles de percée rédigés par de jeunes chercheurs ou des philosophes de réputation internationale. Son principal domaine de publication est l’histoire de la philosophie, qu’elle aborde via des dossiers sur des auteurs, classiques ou contemporains (Aristote, Descartes, Spinoza, Leibniz, Jean Scot Érigène, Duns Scot, Michel Henry, Claude Bruaire, Martin Heidegger, Carl Schmitt, Michel Foucault, etc.), sur des textes (le Discours de Rectorat de Heidegger), sur des problématiques ou des thèmes (Le Pascal des philosophes, La méthode phénoménologique, La philosophie des mathématiques, etc.). La revue publie chaque année quatre numéros ; chaque numéro est composé d’un dossier de 6 ou 7 articles dirigé par un spécialiste français ou étranger du domaine considéré ; les articles en langue étrangère sont toujours traduits en français ; sont joints généralement un ou deux articles dans la rubrique des Varia. La revue s’attache à laisser une part importante à des recensions ou notes de lecture sur des ouvrages significatifs, de langue française ou étrangère, récemment parus. La revue est accessible en version électronique sur Cairn (depuis 2011) et sur Jstor (1928-2005). (shrink)

Having served for a long time under Ostrogothic kings, then removed from office, Cassiodorus (vith century) designed his writings for the members of the famous monastery that he founded at Vivarium. In his monumental Expositio Psalmorum, meant for the novices, he wanted to give his readers not only an exegesis of the biblical text, but rudiments of Liberal Arts too, especially of dialectics and logic. This paper intends to show Cassiodorus’ conception of an orthodox study of dialectics, and his pedagogical (...) devices. Then is considered the way in which Cassiodorus applies in his commentary categorical and hypothetical syllogistics. Finally, special attention is given to Cassiodorus’ rigorous demonstration about the famous Three Chapters controversy. In the dialectical passages of the Expositio appears the artificial cha­racter of this attempt to reconcile secular culture and biblical exegesis. The best in Cassiodo­rus’ enterprise is his enthusiasm. (shrink)

There is a striking difference between the methodology of the young Einstein and that of the old. I argue that Einstein’s switch in the late 1910s from a moderate empiricism to an extreme rationalism should at least in part be understood against the background of his crushing personal and political experiences during the war years in Berlin. As a result of these experiences, Einstein started to put into practice what, drawing on Schopenhauer, he had preached for years, namely to use (...) science as his means of escaping from “the merely personal.” Whatever the exact sources of Einstein’s about-face, the older man has left us with a highly misleading picture of how the younger man achieved the successes that we still celebrate today. This has had a harmful influence on theoretical physics. If the young Einstein’s successes are any guide as to how successful theoretical physics is done, close adherence to general features of the empirical data is much more and mathematical elegance is much less important than the old Einstein wanted us to believe.

Postural instability and balance impairment are disabling symptoms in patients with acute unilateral peripheral vestibular hypofunction. Vestibular rehabilitation is known to improve the vestibular compensation process, but its effect on posture recovery remains poorly understood, little is known about when VR must be done, and whether the degree of vestibular loss matters is uncertain. We analyzed posture control under static and dynamic postural tasks performed in different visual conditions [eye open ; eyes closed ; and optokinetic stimulation] using dynamic posturography. (...) Non-linear analyses of the postural performance were performed in two groups of patients with UVH subjected to the same VR program based on the unidirectional rotation paradigm and performed either early or later after vertigo attack. Distribution of the angular horizontal vestibulo-ocular reflex gain values recorded on the hypofunction side before rehabilitation differentiated two distinct sub-groups with aVOR gains below or above 0.20. The postural performance of the four sub-groups of patients with UVH tested before VR showed significantly altered postural parameters compared with healthy controls. Greater instability, higher energy to control posture, larger sway without feedback corrections, and lower time of automatic control of posture were observed in static conditions. The four sub-groups recovered near-normal postural performance after VR in the EO and EC conditions, but still exhibited altered postural performance with optokinetic stimulation. In dynamic posturography conditions and before VR, the percentage of patients able to perform the postural tasks with EC and optokinetic stimulation was significantly lower in the two sub-groups with aVOR gain <0.20. After VR, the improvement of the postural parameters depended on the stage of rehabilitation and the degree of vestibular hypofunction. The best balance function recovery was found in the sub-group with early VR and pre-rehabilitation aVOR gain above 0.20, the worst in the sub-group with late rehabilitation and aVOR gain below 0.20. These differences were seen when the vestibular input remains the main sensory cue to control balance, that is, on unstable support without vision or altered visual motion cues. These findings extend to dynamic balance recovery the crucial roles of early rehabilitation and degree of vestibular hypofunction which we have already highlighted for vestibulo-ocular reflex recovery.

As I am not at all a specialist on Gottlob Frege’s work, my comments intended initially to be focused on an aspect that emerges in the last part of Peter Clark’s paper “Frege, neo-logicism and applied mathematics” 1, where he treats the question of “applied mathematics” — an aspect that appealed to me and that was triggered by Frege’s relationship between numbers and concepts, and reasoning. Starting with this concern, I have been led by my subject to propose some considerations (...) about foundations and rationality which will go — briefly — in two directions. The first direction is that of a distinction between logical and rational foundations, whilst the second direction is that of taking into account as a fact the historical development of mathematics among the sciences, which modifies the terms of any foundational program. In delineating these considerations, I found that what I had in mind could apply to mathematics itself as well as to “applied mathematics”, thus deviating somewhat from my first explicit intention. In conclusion I shall consider the possibility of a rational foundation programme for mathematical and physico-mathematical sciences which would take into account the changes in the scientific contents and the widenings of the forms of rationality that, in my view, make these changes possible. Such foundations for knowledge would not be any more static, but dynamical and would be possibly considered only retrospectively: they would be “forward foundations”, in a sense that will be discussed in detail elsewhere.

This paper deals with the question whether Seneca’s dramas contain a concept of the tragic. Examining this question this contribution first discusses the studies that have supported the thesis that Seneca’s dramas are anti-tragic. Then it tries by means of the method of the interpretatio stoica to advance a hypothesis how a concept of tragic could be grasped at the background of Seneca’s philosophical thinking. Finally the paper examines this hypothesis at the example of the „Troades“.

This paper is devoted to an analysis of some aspects of Bas van Fraassen’s views on representation. While I agree with most of his claims, I disagree on the following three issues. Firstly, I contend that some isomorphism between the representor and what is represented is a universal necessary condition for the success of any representation, even in the case of misrepresentation. Secondly, I argue that the so-called “semantic” or “model-theoretic” construal of theories does not give proper due to the (...) role played by true propositions in successful representing practices. Thirdly, I attempt to show that the force of van Fraassen’s pragmatic - and antirealist - “dissolution” of the “loss of reality objection” loses its bite when we realize that our cognitive contact with real phenomena is achieved not by representing but by expressing true propositions about them.

I relate the story of how matrix mechanics grew out of the treatment of optical dispersion in the old quantum theory, paying special attention to the contributions of the American theoretical physicists John H. Van Vleck and John C. Slater. Van Vleck shares the credit with Max Born for being the first to publish a full derivation of the crucial Kramers dispersion formula using Bohr’s correspondence principle. Slater was one of the architects of the short-lived but influential Bohr-Kramers-Slater (BKS) theory (...) that helped popularize the so-called Ersatz- or virtual oscillators central both to the treatment of dispersion in the old quantum theory and to the transition to matrix mechanics.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Généalogie de la liberté by Olivier BoulnoisKristell TregoOlivier Boulnois. Généalogie de la liberté. Paris: Seuil, 2021. Pp. 496. Paperback, €24.00.The author starts from an apparently simple question: are we free? But such a question is not as simple as it seems. This book shows that it is neither eternal nor universally asked; rather, it is a question linked to a specific culture (the West), and it has a (...) history. This is why the author intends to draw up its genealogy.In order to draw up a genealogy of the concept of freedom, we must leave aside the standard theoretical framework that assumes freedom as a given. Rather, we should ask: Does [End Page 152] freedom exist? What is its nature? Should it be described as the absence of compulsion or as the power of choice? We must also be wary of any systematic approach to these questions, such as those that have opposed partisans of freedom to determinists or intellectualists to voluntarists throughout the ages. If we want to draw up a genealogy of freedom, we should rather think about the theoretical conditions that made possible the birth and the development of this theoretical "artifact," as Boulnois calls it (23). Contemporary discussions about freedom tend to debate its nature without wondering why such a concept was forged in the first place. By contrast, Boulnois takes a step back and tries to discover the nature of freedom by turning to the moment of its birth.Boulnois has adopted a genealogical approach in his previous books. He used it in his Être et représentation, whose subtitle is une généalogie de la métaphysique moderne à l'époque de Duns Scot (Paris: PUF, 1999). He also mentioned it in the title of a collection of edited essays, where he preferred to talk of "genealogies" in the plural in order to accommodate the diversity of approaches adopted by the authors of the contributions to that volume (Olivier Boulnois, ed., Généalogies du sujet: de saint Anselme à Malebranche [Paris: Vrin, 2007]). In his new book, Boulnois explains his choice of the genealogical method as an attempt to give a history of freedom that might reconcile the so-called continental and analytic approaches (18). Instead of giving a simple description of theories of freedom, by his genealogical method Boulnois intends to show how the Western approach to freedom has resulted in an aporia—the very aporia that Kant diagnosed as an insoluble problem in his Critique of Pure Reason. Boulnois's genealogy should be distinguished from the so-called archeology as heralded by the French scholar of the Middle Ages Alain de Libera. Although both the genealogical and the archeological methods originate in the writings of Michel Foucault, and as such are undeniably connected to each other, the genealogical enterprise is intended to "deconstruct" past philosophers' claims not in order to leave them behind and reject them (as the archeological method intends to do), but rather to become fully aware of those philosophers' theoretical choices and commitments (see Boulnois, Être et representation, 16). Genealogy is thus supposed to "liberate" our thought by making apparent the framework in which we think.To deconstruct the problem of freedom, Boulnois proceeds in four main steps. First, he shows how the problem of freedom is constructed by examining a cluster of related concepts (free will, will, power, and action) and discovering the aporia of free will, which appears to be both indubitable and impossible to conceptualize. Second, Boulnois turns to Aristotle's ethics and theory of action, which conceives of human choices without appealing to the idea of freedom. Third, he considers the "invention of freedom," or better of free will (in Latin, liberum arbitrium voluntatis), by highlighting three main moments: the Stoics' assent to the order of the world; Alexander of Aphrodisias's cogitations, which make room for free will in an Aristotelian framework, even without ever naming it; and finally, Augustine's reorganization of ethics around the very concept of free will. Fourth and finally, Boulnois focuses on the medieval debates concerning freedom and the way they contributed to contrasting human beings with the... (shrink)

Toute science, admet-on, commence par détacher un objet en le rendant indépendant des sujets et des situations. Mais cette conception étroite de la connaissance scientifique laisse subsister des zones d'ombre. La conscience n'est pas un objet. Elle est ce sans quoi rien ne pourrait être pris pour objet. La conscience n'est pas détachable des sujets, car elle s'identifie à ce qui est vécu par un sujet. De façon analogue, en physique quantique, un phénomène n'est pas dissociable de son contexte expérimental, (...) car il s'identifie à ce qui se manifeste à grande échelle au laboratoire. Que faire pour ne pas laisser ces cas extrêmes de côté? Généraliser la méthode scientifique. Ne plus la borner à définir et à caractériser des objets, mais l'étendre à la coordination directe des expériences. Telle est la révolution de pensée qu'il faut accomplir pour résoudre, ou plutôt dissoudre, deux questions-limites de la science : le problème de l'origine de la conscience et le paradoxe du "chat de Schrödinger" en physique quantique.

L'ONTOLOGIE comme question de l'Etre aura dominé le XXe siècle, avec L'Etre et le Temps de Heidegger et l'Etre et le Néant de Sartre. Mais que dire sur l'Etre sans le présupposer, sans dire qu'il est ceci ou cela alors que c'est ce dire même qui fait problème? L'Etre se présente ainsi comme la problématicité de la philosophie, et c'est du même coup cette problématicité qui pose question avant tel ou tel objet, aussi éminent soit-il. En se voulant interrogation sur (...) l'Etre, la philosophie néglige de prendre en compte l'être de sa propre interrogation, et de s'interroger non seulement sur son questionnement, mais sur le questionnement en général, qu'elle met cependant en œuvre comme une évidence. Le but de cet ouvrage est d'analyser, de Platon à Heidegger, en passant par Kant, Sartre, Bergson et Wittgenstein, les apories de l'ontologie et leur dépassement par la thématisation du questionnement, la problématologie. Car qu'est-ce que la philosophie sinon un questionnement radical, à questionner enfin comme tel, et non plus au travers de l'Etre ou du sujet? MICHEL MEYER. (shrink)

This commentary on Gert Goeminne’s paper “Postphenomenology and the politics of sustainable technology” elaborates on the subpolitics of technology as a basis for dealing with sustainability issues. It questions the “sustainable technology” phrasing of the issue and focuses on the political/post-political debate to eventually suggest that the politics of sustainable technology is a possible post-political question. Minor disagreements on some philosophy of science references are briefly expressed.
