Strictly speaking the law cannot admit toleration: It cannot tolerate ideas or behaviour which are contrary to its requirements. This logic explains why for centuries civilizations found no place for toleration. Then in the seventeenth and eighteenth centuries, philosophers and thinkers such as Spinoza, Locke, Bayle and later Voltaire or Malesherbes advocated tolerance, certain aspects of which were to be introduced into the legislation of many countries: freedom of opinion, the free movement of persons, freedom of assembly and of religion.

The philosopher of Mathematics Jean Cavaillès plays an important role in Claude Imbert's thought. His published work had a significant impact after the war. It is largely a reflection on debates on the foundation of mathematics and on two opposed models of axiomatics, foundationalist and constructionist. The philosophy he announced was to be a study of the generativity of conceptual structures, as opposed to a phenomenology of knowledge. He derived from his reflection on invention in mathematics a great (...) scepticism on the ideas of the separateness and unity of consciousness and a criticism of the teleologies inherent in philosophies of consciousness. In that, his work, according to Claude Imbert, made possible the reflections on structures and symbolisms which were to dominate the French context in the following decades. (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)

"In this groundbreaking book Jean Walton subjects psychoanalysis to a sustained and highly illuminating ethnographic critique.

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)

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)

Comment Bachelard, fils d'un cordonnier, professeur de physique et chimie, a-t-il pu devenir cet humaniste aussi savant que philosophe, aussi penseur que poète? Il n'a pas emprunté les chemins balisés, ceux des élites universitaires et culturelles. Il a contrarié les pronostics et les conventions. Il s'est adjugé contre vents et marées le droit de penser par lui-même en bousculant les frontières des savoirs et de la culture et en dérangeant les us et coutumes établis.

Scientific models need to be investigated if they are to provide valuable information about the systems they represent. Surprisingly, the epistemological question of what enables this investigation has hardly been investigated. Even authors who consider the inferential role of models as central, like Hughes or Bueno and Colyvan, content themselves with claiming that models contain mathematical resources that provide inferential power. We claim that these notions require further analysis and argue that mathematical formalisms contribute to this inferential role. We characterize (...) formalisms, illustrate how they extend our mathematical resources, and highlight how distinct formalisms offer various inferential affordances. (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)

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)

The roles models play in science have long been recognised and sparked rich and varied philosophical debates. In recent years attention has also been paid to the computational techniques used in the sciences, and the question arose what the implications were of the use of computer simulations for our understanding of scientific modelling, and science more generally. This was the subject of the conference “Models and Simulations”, which took place at the IHPST in Paris in June 2006. Selected papers of (...) that conference appeared in a special issue of this journal (Synthese 169(3) (2009)). After the conference there was a general feeling that there still was much ground to cover, and so we decided to organize a follow up a year later. “Models and Simulations 2” took place in October 2007 at the Tilburg Center for Logic and Philosophy of Science (TiLPS) in the Netherlands. The conference was made possible due to generous financial support from IHPST (Paris, CNRS), Universitat de Barcelona, TiLPS (Tilburg Center for Logic and Philosophy of Science) and the Evert Willem Beth Foundation. The papers in this special issue were presented at the conference and selected after a double-blind review process. We would like to thank the authors and referees of the papers for their work, and Vincent Hendricks and John Symons for their support of the project of another special issue on models and simulations.

We analyze the effects of the introduction of new mathematical tools on an old branch of physics by focusing on lattice fluids, which are cellular automata -based hydrodynamical models. We examine the nature of these discrete models, the type of novelty they bring about within scientific practice and the role they play in the field of fluid dynamics. We critically analyze Rohrlich's, Fox Keller's and Hughes' claims about CA-based models. We distinguish between different senses of the predicates “phenomenological” and “theoretical” (...) for scientific models and argue that it is erroneous to conclude, as they do, that CA-based models are necessarily phenomenological in any sense of the term. We conversely claim that CA-based models of fluids, though at first sight blatantly misrepresenting fluids, are in fact conservative as far as the basic laws of statistical physics are concerned and not less theoretical than more traditional models in the field. Based on our case-study, we propose a general discussion of the prospect of CA for modeling in physics. We finally emphasize that lattice fluids are not just exotic oddities but do bring about new advantages in the investigation of fluids' behavior. (shrink)

For two centuries, collaborative research has become increasingly widespread. Various explanations of this trend have been proposed. Here, we offer a novel functional explanation of it. It differs from ac- counts like that of Wray by the precise socio-epistemic mech- anism that grounds the beneficialness of collaboration. Boyer-Kassem and Imbert show how minor differences in the step-efficiency of collaborative groups can make them much more successful in particular configurations. We investigate this model further, derive robust social patterns concerning the (...) general successfulness of collaborative groups, and argue that these patterns can be used to defend a general functional account.

Cellular Automata (CA) based simulations are widely used in a great variety of domains, fromstatistical physics to social science. They allow for spectacular displays and numerical predictions. Are they forall that a revolutionary modeling tool, allowing for “direct simulation”, or for the simulation of “the phenomenon itself”? Or are they merely models "of a phenomenological nature rather than of a fundamental one”? How do they compareto other modeling techniques? In order to answer these questions, we present a systematic exploration of (...) CA’s various uses. (shrink)

Why are some models, like the harmonic oscillator, the Ising model, a few Hamiltonian equations in quantum mechanics, the poisson equation, or the Lokta-Volterra equations, repeatedly used within and across scientific domains, whereas theories allow for many more modeling possibilities? Some historians and philosophers of science have already proposed plausible explanations. For example, Kuhn and Cartwright point to a tendency toward conservatism in science, and Humphreys emphasizes the importance of the intractability of what he calls “templates.” This paper investigates more (...) systematically the reasons for this remarkable interdisciplinary recurrence. To this aim, the authors describe in more detail the phenomenon they focus on and review competing potentialexplanations. The authors disentangle the various assumptions underlying these explanations based on sensitivity to a computational constraints and assess its relationships with the other analyzed explanatons.

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)

Parues pour la premiere fois en 1938, les Etudes kierkegaardiennes de Jean Wahl constitutent a tous egards une somme incontournable pour comprendre le sens de la philosophie de Kierkegaard et la place si originale qu'elle occupe dans l'histoire de la philosophie. L'auteur s'efforce d'y faire apparaitre le lien existant entre les evenements qui marquerent la vie de Kierkegaard et la formation de ses concepts fondamentaux. Par ce biais, l'auteur montre comment la theorie des trois stades de l'existence fait appel (...) a une dialectique qualitative, opposee a la dialectique hegelienne. L'auteur montre enfin que la theorie des trois stades de la croyance et de l'existence qui lui sont liees sont inseparables d'une lutte entreprise contre les pensees qui contribuerent a la genese de la pensee de Kierkegaard et qu'il s'agit a present pour lui de depasser: il n'y a pas de chemin qui conduit de la pensee, du cogito, a l'etre, au sum, car l'existence est l'etre hors de toute pensee.

One of the most perceptive and ambidextrous social commentators of our day, Augustinian scholar Jean Bethke Elshtain furnishes in ever fresh ways through her writings a bridge between the ancient and the modern, between politics and ethics, between timeless moral wisdom and cultural sensitivity. To read Elshtain seriously is to take the study of culture as well as the "permanent things" seriously. But Elshtain is no mere moralist. Neither is she content solely to dwell in the domain of the (...) theoretical. For it is Elshtain the citizen - the creatively engaged and contributing citizen - whom the reader encounters on virtually every page of her writings. But reader beware: Elshtain does not shy away from controversy. At the same time, she is anything but a controversialist. In the essay that follows, several prominent themes that emerge from Elstain's writings - civic responsibility, justice, gender, and war - are considered afresh. Whether one agrees with her positions or not, one is forced to confess in the end that she cares deeply about the common good. And this alone makes her required reading for any engaged citizen of the republic. (shrink)

Y a-t-il une psychanalyse chrétienne? Cette question a-t-elle un sens? Un croyant souffrant doit-il ou non s'assurer que son psychanalyste est lui-même croyant pour protéger sa foi? Autrement dit, comment l'analyse intègre-t-elle ou modifie-t-elle une donnée religieuse? Faire une analyse, c'est accepter de traverser le tragique de sa propre vie. En raison du dévoilement de la vérité que ce processus met en œuvre, le patient voit se dégager devant lui la perspective d'un désir dont la nouvelle mesure est infinie. Ce (...) désir avait été comblé par des objets qui, jusque-là, semblaient le satisfaire. Puis, le symptôme surgit, déstabilise, perturbe les petits arrangements que le patient s'était autorisés. Première ou dernière scène de son tragique? Dans le huis clos théâtral qu'est la séance analytique, le patient-acteur reprend et parle toute son histoire. Comme à son insu, il se voit contraint de redéfinir ce qui donne sens à sa vie : sens religieux? sens éthique? Bref, tout ce qui échappe à l'analyse et que, paradoxe imprévisible, elle évoque et convoque... Pourtant, un point restera toujours aveugle pour lui, à l'instar d'Œdipe qui, les yeux crevés, poursuit son chemin. C'est peut-être en ce même point - tragique-aveugle - que l'homme reconnaît sous une lumière nouvelle que son histoire personnelle rejoint la détresse commune et ordinaire de toute l'humanité.

" L'homme a toujours pensé que le visage du monde devait l'instruire sur lui-même. " Fort de cette certitude, le philosophe et historien des sciences français Jacques Merleau-Ponty a cherché toute sa vie à donner un sens à l'extraordinaire histoire que nous racontent les astronomes contemporains. Or le visage de l'univers actuel est une véritable énigme pour l'homme moderne : origine inaccessible, histoire chaotique, espace infini, temps relatif, avenir imprévisible... A l'accumulation des connaissances, il fallait répondre par le courage de (...) la pensée. Contemporain de toutes les découvertes cosmologiques du XXe siècle, Jacques Merleau-Ponty a été un des très rares philosophes à y réfléchir pour redonner une place à l'homme dans cet ensemble démesuré. Car si la science cosmologique appartient aux spécialistes, la description du ciel est un bien commun et la pensée du big bang une nouvelle nécessité. Ce livre expose pour la première fois cette pensée qui prend le risque de poser la plus universelle et intime des questions : quel est le sens de l'univers? Depuis Copernic, l'homme n'est décidément plus au centre du cosmos mais il est toujours au coeur de sa signification. (shrink)
