This book promotes the research of present-day women working in ancient and medieval philosophy, with more than 60 women having contributed in some way to the volume in a fruitful collaboration. It contains 22 papers organized into ten distinct parts spanning the sixth century BCE to the fifteenth century CE. Each part has the same structure: it features, first, a paper which sets up the discussion, and then, one or two responses that open new perspectives and engage in further reflections. (...) Our authors’ contributions address pivotal moments and players in the history of philosophy: women philosophers in antiquity, Cleobulina of Rhodes, Plato, Lucretius, Bardaisan of Edessa, Alexander of Aphrodisias, Plotinus, Porphyry, Peter Abelard, Robert Kilwardby, William Ockham, John Buridan, and Isotta Nogarola. The result is a thought-provoking collection of papers that will be of interest to historians of philosophy from all horizons. Far from being an isolated effort, this book is a contribution to the ever-growing number of initiatives which endeavour to showcase the work of women in philosophy. (shrink)

In this article, we begin by questioning the notion of special educational needs, which is used today in Switzerland, by going back over its historical foundations and developing the main issues and problems it raises. We then present the results of a comprehensive research aimed at uncovering the factors at work in the process of designating certain students for an enhanced special education support measure during their compulsory schooling. On the basis of a content analysis of the reports for an (...) enhanced special education support measure produced during the 2016-2017 school year in a Swiss canton, as well as comprehensive interviews conducted with permanent teachers, we highlight various factors that can lead to the designation of a student for an enhanced special education support measure. We show how there is a degree of randomness in being designated for a special education support measure and critically discuss the role of the school institution and its actors in this process.

Depuis qu'elles existent, les sciences dites exactes se prétendent différentes des autres savoirs. Comment comprendre cette prétention? Faut-il, à la manière des épistémologues anglo-saxons ou de Karl Popper, tenter d'identifier les critères qui la justifient? Peut-on, suivant le modèle nouveau des études sociales des sciences, y voir une simple croyance? Ce livre propose un dépassement fructueux de l'opposition, apparemment irréconciliable, entre ces deux approches des sciences. Et si la tension entre objectivité scientifique et croyance était justement constitutive des sciences, enjeu (...) des pratiques inventées et réinventées par les scientifiques? Réussir à parler des sciences avec humour, sans en faire un objet de vénération, ni de dénonciation, en restant au plus proche de la passion des scientifiques, tel est ici le pari d'Isabelle Stengers. Mais ce livre ne se limite pas à un discours sur les sciences. Il s'agit bien plutôt de prolonger l'histoire de leur invention. Comment comprendre les liens multiples entre la science et les pouvoirs qui la mobilisent aujourd'hui? Comment concevoir les rapports entre science, expertise et démocratie? La nouveauté de L'invention des sciences modernes est de faire de ces différents problèmes intellectuels, pratiques et politiques les enjeux du processus par où pourrait s'inventer et se renouveler l'identité même des sciences.

"Isabelle Stengers presents us with a new way of understanding a remarkably diverse range of sciences and their relation to a material and living world. Playing with a position both inside the practices that constitute and transform science and outside the sciences as their mode of conceptualization, Stengers explores the limits, constraints, and inventions that fuse modern science and contemporary society."

De longue date, les sciences dites " humaines et sociales " ont eu l'ambition d'appliquer à leurs objets les mêmes critères de rigueur scientifique que les sciences dites " exactes ". Mais les hommes et les sociétés sont des " objets " bien différents des neutrinos ou des bactéries, et les pratiques scientifiques, quand elles prétendent s'y appliquer, subissent une redoutable transformation : armé de concepts - croyance, motivation, opinion, habitude et même culture -, le scientifique rationnel cherche à se (...) différencier des objets humains ou sociaux qu'il décrit ; ce faisant, il ne peut que les réduire et donc les disqualifier dans leur complexité. Quitte ensuite à invoquer l'humaine vertu de tolérance pour nous exhorter à respecter les croyances ou les convictions qui échappent au savoir scientifique. C'est contre cet abus de pouvoir et cette faiblesse qu'Isabelle Stengers s'élève dans ce livre. Elle plaide pour que les sciences dites humaines et sociales abandonnent leurs fausses ressemblances avec les sciences dites " dures ". Ces dernières ont fait converger science et technique, pouvoir de connaître et pouvoir de transformer ; il appartient peut-être aux sciences " molles " de les faire diverger... Cette approche permet à l'auteur de proposer ici une synthèse des investigations menées dans les six premiers volumes de " Cosmopolitiques " : elle tente de répondre à la question cosmopolitique, celle de savoir comment et à quel prix les pratiques modernes, qui ont mis à jour les microbes et les électrons, les pratiques techniques, qui créent un autre ordre de savoirs, et les pratiques non modernes, qui font intervenir des êtres surnaturels, pourraient coexister en paix. Une paix qui ne serait pas d'indifférence ou de tolérance, car production de savoirs et production de relations y seraient indispensables. (shrink)

Concerned with the interplay between science, society, and power, Isabelle Stengers offers a unique perspective on the power of scientific theories to modify society, and vice versa. 9 diagrams.

Although the mapping between form and meaning is often regarded as arbitrary, there are in fact well-known constraints on words which are the result of functional pressures associated with language use and its acquisition. In particular, languages have been shown to encode meaning distinctions in their sound properties, which may be important for language learning. Here, we investigate the relationship between semantic distance and phonological distance in the large-scale structure of the lexicon. We show evidence in 100 languages from a (...) diverse array of language families that more semantically similar word pairs are also more phonologically similar. This suggests that there is an important statistical trend for lexicons to have semantically similar words be phonologically similar as well, possibly for functional reasons associated with language learning.

Noel Carroll, film scholar and philosopher, offers the first serious look at the aesthetics of horror. In this book he discusses the nature and narrative structures of the genre, dealing with horror as a "transmedia" phenomenon. A fan and serious student of the horror genre, Carroll brings to bear his comprehensive knowledge of obscure and forgotten works, as well as of the horror masterpieces. Working from a philosophical perspective, he tries to account for how people can find pleasure in having (...) their wits scared out of them. What, after all, are those "paradoxes of the heart" that make us want to be horrified? (shrink)

“Forget Taste” rejects the classical notion of taste as a viable concept for the exercise of critical evaluation and proposes an alternative approach to critical evaluation based crucially on the idea of the constitutive purpose of the artwork. The goal of this paper is to advance an approach—which I call the purpose-driven approach—to the critical evaluation of artworks that develops from and refines the views of art evaluation presented in my previous work. This approach, in virtue of its focus on (...) the constitutive purposes of artworks, regards the artwork as typically singular. For that reason, it follows that this approach is pluralistic in contrast to the hedonic conception of the taste model popularized in the eighteenth century and which still recurs today, if sometimes only subconsciously, and that reduces critical evaluation to feelings of pleasure. I argue that the hedonic taste model, which is noncognitive and reductive, should be abandoned in favor of one that is cognitivist and pluralistic, namely, the purpose-driven approach. (shrink)

According to spacetime state realism, the fundamental ontology of a quantum mechanical world consists of a state-valued field evolving in four-dimensional spacetime. One chief advantage it claims over rival wave-function realist views is its natural compatibility with relativistic quantum field theory. I argue that the original density operator formulation of SSR cannot be extended to QFTs where the local observables form type III von Neumann algebras. Instead, I propose a new formulation of SSR in terms of a presheaf of local (...) state spaces dual to the net of local observables studied by algebraic QFT. 1Introduction2Spacetime State Realism in Quantum Field Theory 2.1Equivalence thesis3Entanglement and the Type III Property 3.1No-Go Lemma 13.2No-Go Lemma 24State Space Axioms for Quantum Field Theory 4.1Revised equivalence thesis5Discussion.

"The Invention of Modern Science proposes a fruitful way of going beyond the apparently irreconcilable positions, that science is either "objective" or "socially constructed." Instead, suggests Isabelle Stengers, one of the most important and influential philosophers of science in Europe, we might understand the tension between scientific objectivity and belief as a necessary part of science, central to the practices invented and reinvented by scientists."--pub. desc.

In den Mittelpunkt der Schrift stellt Nicolaus Cusanus die Figur eines Laien (idiota), der – als Gegenpol zum universitär ausgebildeten Philosophen – den einfachen Ungebildeten und damit die wahre Weisheit repräsentiert, die dem Geist des Menschen und seinen Potentialen entspricht. Statt auf Bücherwissen und Autoritäten setzt er auf das eigene Philosophieren, das immer neu nach der Wahrheit fragt. Der Laie verkörpert die cusanische Philosophie in besonderem Maße: Fundamentale anthropologische, erkenntnistheoretische und metaphysische Bestimmungen des Cusanus finden sich hier in einer Gestalt (...) vereint. Aus dem Wissen heraus, dass menschliches Erkennen immer nur mutmaßend sein kann, geht es um das rechte kritische Verhältnis zu den eigenen Erkenntnismöglichkeiten. An der Figur des Laien macht Cusanus deutlich, dass dies keineswegs in einen erkenntnistheoretischen Skeptizismus führt, der die Möglichkeit sicheren Wissens von vornherein für nicht erreichbar und infolgedessen alle Erkenntnisbemühungen für überflüssig hält, sondern dass darin das unendliche und dynamische Potential des Menschen zum Ausdruck kommt, sich unermüdlich an die Wahrheit anzunähern. In der Geschichte der Erkenntnistheorie vor Kant spielt "Der Laie über den Geist" somit eine fundamentale Rolle. (shrink)

Few today can escape exposure to mass art. Nevertheless, despite the fact that mass art provides the primary source of aesthetic experience for the majority of people, mass art is a topic that has been neglected by analytic philosophers of art. The Philosophy of Mass Art addresses that lacuna. It shows why philosophers have previously resisted and/or misunderstood mass art and it develops new frameworks for understanding mass art in relation to the emotions, morality, and ideology.

In this paper, I both propose and discuss a novel account of truthmaking. I begin by showing what truthmaking is not: it is not grounding and it is not correspondence. I then show what truthmaking is by offering an account that appeals both to grounding and what I call ‘deep correspondence’. After I present the account and show that it is an account that unifies, I put it to work by showing how it can overcome an objection to truthmaking, how (...) we can get truthmaking from correspondence, what it says about truthmaker necessitation, and how it can explain a connection between truthmaker maximalism and pluralism about truth.

Several tasks in artificial intelligence require the ability to find models about knowledge dynamics. They include belief revision, fusion and belief merging, and abduction. In this paper, we exploit the algebraic framework of mathematical morphology in the context of propositional logic and define operations such as dilation or erosion of a set of formulas. We derive concrete operators, based on a semantic approach, that have an intuitive interpretation and that are formally well behaved, to perform revision, fusion and abduction. Computation (...) and tractability are addressed, and simple examples illustrate the main results. (shrink)

En ce XXe siècle, où la physique s'est identifiée à la science révolutionnaire par excellence, l'œuvre passionnée d'Ilya Prigogine constitue une singulière anomalie. Anormale parce qu'elle prend le parti du monde des phénomènes physiques contre le pouvoir de la théorie, jugé abusif ; mais anormale aussi par sa longue obstination à une époque où la rapidité fait foi. Le combat avait commencé au début des années soixante, sur un mode mineur : Prigogine demandait à ses collègues de reconnaître qu' " (...) il y a certainement une signification physique profonde dans l'équation de Boltzman ". Thèse apparemment bien légitime : l'équation de Boltzmann permet de décrire avec succès le comportement de non-équilibre des gaz dilués. Mais thèse iconoclaste : car, depuis que la croissance de l'entropie a été renvoyée aux seules probabilités, le comportement de non-équilibre n'est plus sensé autoriser la moindre " signification profonde ". Raconter l'histoire de ce combat, comme le fait Isabelle Stengers dans ce livre, revient à interroger les lois fondamentales sous l'angle du lien entre théorie, valeur et obligation. En effet, sans ce lien, ni la position de Prigogine ni celle des physiciens contre qui il va chercher des arguments toujours plus puissants ne sont intelligibles. L'auteur montre que ce lien permet d' " inventer " des problèmes : Il y a Prigogine qui oppose ainsi des lois nouvelles, les " lois du chaos ", au déterminisme absolu des lois fondamentales de la physique. La physique est habitée par la passion de la loi, mais la manière dont cette passion est ici réinventée pourrait ouvrir de nouvelles voies, vitales pour une " écologie des pratiques ". Serait-il possible que le physicien ne se présente plus comme celui par qui s'opère la fascinante découverte des lois de la nature? Serait-il possible de célébrer avec lui l'extraordinaire aventure que constitue l'invention d'un objet capable de dicter la manière dont il doit être décrit? (shrink)

There seem to be at least two leading conceptions of art appreciation. The first, and by far the most popular, it seems to me, regards “appreciation” as a synonym for “approbation,” which itself can be a synonym for affection or even love. “To appreciate,” in this sense, is “to cherish.” This is the notion of appreciation that most plain speakers have in mind when they say things such as “I appreciate what you’ve done with your garden.” They mean “I like (...) what you’ve done with your garden.” Call this “appreciation-as-liking.” Although I’ve claimed that this is the popular construal of appreciation, it also possesses some estimable philosophical credentials. David Hume, for example, seems to hold a... (shrink)

The paper provides a new critical perspective on the propensity interpretation of fitness, by investigating its relationship to the propensity interpretation of probability. Two main conclusions are drawn. First, the claim that fitness is a propensity cannot be understood properly: fitness is not a propensity in the sense prescribed by the propensity interpretation of probability. Second, this interpretation of probability is inessential for explanations proposed by the PIF in evolutionary biology. Consequently, interpreting the probabilistic dimension of fitness in terms of (...) propensities is neither a strong motivation in favor of this interpretation, nor a possible target for substantial criticism.

Providing a compelling scholarly statement about the interrelation and pliability of values in the life sciences, medicine and health care, this volume aims to aid our understanding of the roles of power, knowledge production and economic action in the heavily scientised and economised areas of life science and medicine.

Pourquoi les sciences modernes n'avancent-elles que sur le mode guerrier - guerre du scientifique contre ses concurrents, guerre du savant contre le " charlatan ", guerre du " nouveau " contre l' " ancien "? Pourquoi ces sciences sont-elles présentes parmi nous sous le jour le plus faux : triomphe d'un savoir enfin objectif, neutre et désintéressé, produit par une démarche méthodique, humble et sereine? Et pourquoi, lorsque les scientifiques osent dire leurs rêves et leurs ambitions, est-ce si souvent la (...) spéculation arrogante, le mépris et la polémique qui trouvent à s'exprimer? Les savoirs modernes sont aujourd'hui habités par une obsession de la différenciation. Et cette obsession de la différence à rappeler, de l'opposition à maintenir, entre objectivité scientifique et savoirs subjectifs, les voue à exister sur le mode de la guerre généralisée, guerre défensive ou offensive de chacun contre les autres, guerre de tous contre ce qu'ils s'accordent à disqualifier en tant que simple opinion. Est-il possible de civiliser les savoirs modernes, d'inventer entre eux et avec nous un régime de coexistence pacifique? Est-ce possible, sans leur demander de renoncer aux rêves et aux passions qui les font exister, sans exiger qu'ils se soumettent, au nom de cette paix à établir, à un quelconque tribunal distribuant les droits et les devoirs de chacun? C'est pour construire une réponse à cette question qu'Isabelle Stengers tente ici une démarche tout à la fois de diagnostic et de pronostic. Car il s'agit tout aussi bien de comprendre les valeurs que font exister les sciences, que de risquer un pari sur un avenir possible où ces valeurs seraient activement dissociées du pouvoir de disqualifier. Le projet d'une mise en culture des sciences n'a rien à voir, alors, avec un quelconque supplément d'âme, ou une meilleure diffusion des connaissances scientifiques. Pour Isabelle Stengers, il passe par la construction de ce qu'exigerait une véritable écologie des pratiques, modernes et non modernes. (shrink)

L'énergie se conserve! Cet énoncé scientifique, le premier à pouvoir concerner tous les processus naturels, du mouvement planétaire au métabolisme vivant, du feu qui brûle à la pile électrique, a constitué, au milieu du siècle dernier, un véritable événement. Tous, physiciens, chimistes, ingénieurs, médecins, philosophes, sont concernés. Comment concevoir cette énergie qui semble dire, à la fois, l'unité de la nature et sa diversité? Et pourtant, à la fin du XIXe siècle, il ne reste plus que des physiciens, et ceux-ci (...) semblent avoir réussi à concentrer le problème autour d'une grandeur mystérieuse, qu'eux seuls savent définir, l'entropie. Un siècle plus tard, la physique du XXe siècle est devenue cette science habitée par la conviction que le monde est, comme l'a dit Einstein, énigmatiquement intelligible, et qu'il appartient aux physiciens, au nom de tous les humains, d'en percer l'énigme. Pour comprendre comment ce pouvoir exorbitant a été conquis, c'est vers ce moment critique du XIXe où s'est jouée la notion de " réalité physique " - réalité du monde ou réalité construite par les questions des physiciens? - qu'il s'agit de remonter. C'est ce que tente ici Isabelle Stengers, en retraçant la controverse étonnante qui mobilisa Clausius, Engels, Thomson, Maxwell, Planck, Poincaré, Mach, Duhem, Botzmann. Avec une brutalité exemplaire, l'issue de cette controverse a défini vainqueurs et vaincus : vainqueurs, ils appartiennent à l'histoire de la physique ; vaincus, leur intervention dans la question de la réalité physique a été renvoyée à l'épistémologie et à la philosophie. Que s'est-il passé? Pourquoi est-ce par le triomphe de la loi que l'histoire " est passé "? La singularité des choix qui ont fait exister la physique du XXe siècle n'a pas à être critiquée, mais peut être racontée, à la manière d'une véritable histoire. (shrink)

RésuméLes querelles constituent une activité « routinière » plutôt qu’extra ordinaire du monde lettré et savant. Nous montrons ici qu’elles ont un rôle à jouer dans le domaine de la critique historique. Notre apport est double. En nous intéressant aux enjeux épistémologiques de l’écriture baylienne de la querelle, nous transposons sur le terrain de l’historiographie l’apport des études récentes sur la productivité des querelles scientifiques. Nous présentons une perspective nouvelle de compréhension des querelles comme activité structurante de la république des (...) lettres, tant sur le plan social qu’intellectuel. Ce faisant, nous prenons position dans le débat sur le « pyrrhonisme » historique de Bayle en montrant que les querelles sont centrales dans une démarche historio graphique consciente de ses limites comme de ses pouvoirs d’investigation.

Toward the end of his book Jokes, perhaps the best known philosophical treatment of the subject, Ted Cohen includes a notorious joke about a group of young Black men who are deterred from committing a gang rape by being thrown a basketball. This is a joke that perplexes Cohen and that he admits plays into stereotypes that presuppose the mindless obsession of Black youths with basketball as well as their unbridled sexuality. He agrees that the joke is morally bad and (...) that it would be a better world without it. But he denies that its evil compromises its alleged funniness. He writes: “Wish that there were no mean jokes. Try remaking the world so that such jokes will have no place, will not arise. But do not deny that they are funny. That denial is a pretense that will help nothing.” In this paper, I want to challenge the claim that the moral defectiveness of a joke, especially a racist joke, cannot ever compromise its capacity to be funny.

Growing inequality and its implications for democratic polity suggest that corporate social responsibility has not proved itself in twenty-first century business, largely as it lacks clear criteria of demarcation for businesses to follow. Today the problem is viewed by many commentators as an ethical challenge to business itself. In response to this challenge, we begin by examining Porter and Kramer’s :64–77, 2011) call for a shift from a social responsibility to a shared value framework and the need to respond to (...) the problem of the ‘separation thesis’ between business and ethics :89–118, 1996; Harris and Freeman, Bus Ethics Q 18:541–548, 2008). We identify the eighteenth century economist and philosopher Adam Smith in his book The Theory of Moral Sentiments as a source for an ethical approach to business. Building on his central concept of ‘sympathy’, we introduce the idea of the Impartial Spectator Test, which we argue builds on traditional stakeholder perspectives and which provides an objective route to ethical criteria of demarcation. We conclude by assessing how this approach adds to the existing debate around social responsibility and shared value. (shrink)

It is sometimes said that simulation can serve as epistemic substitute for experimentation. Such a claim might be suggested by the fast-spreading use of computer simulation to investigate phenomena not accessible to experimentation. But what does that mean? The paper starts with a clarification of the terms of the issue and then focuses on two powerful arguments for the view that simulation and experimentation are ‘epistemically on a par’. One is based on the claim that, in experimentation, no less than (...) in simulation, it is not the system under study that is manipulated but a system that ‘stands-in’ for it. The other one highlights the pervasive use of models in experimentation. It will be argued that these arguments, as compelling as they might seem, are each based on a mistaken interpretation of experimentation and that, far from simulation and experimentation being epistemically on a par, they do not have the same epistemic function, do not produce the same kind of epistemic results.

Virginia Woolf, to whom university admittance had been forbidden, watched the universities open their doors. Though she was happy that her sisters could study in university libraries, she cautioned women against joining the procession of educated men and being co-opted into protecting a “civilization” with values alien to women. Now, as Woolf's disloyal daughters, who have professional positions in Belgian universities, Isabelle Stengers and Vinciane Despret, along with a collective of women scholars in Belgium and France, question their academic (...) careers and reexamine the place of women and their role in thinking, both inside and outside the university. They urge women to heed Woolf's cry—Think We Must—and to always make a fuss about injustice, cruelty, and arrogance. (shrink)

The heart of Aristotelian Logic is the square of opposition. This study engaged on further [re]investigation and meta-logical analysis of the validity of the square of opposition. Further, in this paper, it has been modestly established, with greater clarity, the exposition of the strengths, more than the presentation of the defects, loopholes and weaknesses, of the Aristotelian Logic in a descriptive and speculative manner. The unconcealment of the breakdown of the square of opposition marked a rupture and the opening of (...) avenues of alternative reasoning. The critical and analytical exposition of the loopholes of the square of opposition led to a realization that things around us could have been and still be different; and there could have been better alternative reasoning than what we have called, adopted, and worshipped [Greek] logic. Results show that the downfall of the oppositional relationships in the square of opposition provided a proof of the logical illusion of Aristotle or the loophole of Traditional Logic. The laws of opposition, that have been considered the measures of logically deductive inferences, are practically almost totally logical deceptions. By implication, if the laws of subcontrariety, contrariety, and subalternation [and may be contradiction] have collapsed, the square of opposition has also collapsed; hence, Aristotle‟s square of opposition is a fallacy. This means that the square of opposition has errors and in itself an error. (shrink)
