Este trabalho objetiva pesquisar sob uma perspectiva histórico-epistemológica o desenvolvimento da acústica musical no Renascimento. Tal investigação será especialmente focada na busca de indicadores da importância da verificação experimental na produção do conhecimento acústico nesse período. Com o intuito de extrair os indicadores mencionados, assim analisou-se tratados teórico-musicais desse período sob uma perspectiva das relações entre a física, a matemática e a música. Do ponto de vista educacional, o presente projeto pretende, por meio de uma exposição didática no museu Estação Ciência, reproduzir estruturalmente experimentos esclarecedores de conceitos acústicos emergentes na Revolução Científica, fazendo uso de recursos modernos. Como resultado bibliográfico de tais reflexões, foi organizada uma discussão sobre um conjunto de estratégias de ensino sobre a relação entre física, matemática e música, sob uma perspectiva histórico-epistemológica. Além disso, o presente trabalho relatou o processo de desenvolvimento de uma exposição didática sobre a relação entre a matemática, a física e a música. Tal exposição busca reconstruir os principais experimentos da história da acústica musical responsáveis pela consolidação da teoria que conhecemos atualmente, evidenciando os indicadores da importância da verificação experimental na produção do conhecimento acústico na história da ciência. Neste sentido, torna-se fundamental que a pesquisa historiográfica forneça subsídios teóricos para a fundamentação da transição de uma ciência musical centrada em um dogmatismo aritmético para uma ciência musical, que tem a verificação experimental como critério relevante de falseamento de suas teorias. Desta forma, o presente trabalho pretende apresentar a exposição didática que será realizada no museu Estação Ciência, reproduzindo por escrito sua estrutura, experimentos e painéis que visam esclarecer conceitos acústicos emergentes na Grécia Antiga e suas transformações ao longo da Revolução Científica. / This project aims to research under a historic-epistemological perspective the development of musical acoustic in the Renaissance. This research will be especially focused in the search for indicators of the importance of experimental verification in the production of acoustic knowledge of that time. Therefore, it becomes essential that the historiografical search provide theoretical subsidies for reasoning of the transition from a science musical centered on a dogmatism arithmetic to a science musical, which has a verification test as a relevant criterion of distorted from their theories. In order to extract the indicators mentioned, the aim is to analyze well-treated theoretical music of this period under the prospect of relations between the physics, mathematics and music. From an educational overview, this project intends, through a didactic exhibition at the museum \"Estação Ciência\", to reproduce structurally clarifying experiments of acustical concepts emerged in the Scientific Revolution, making use of modern resources. As a result of such bibliographic thoughts, it is intended to discuss various teaching strategies on the development of the relationship between physics, mathematics and music, on a perspective historic-epistemological. Then this project aims to describe the process of the development of a didactic exposition about the relation between mathematics, physics and music under a historicepistemological perspective. Such exposition intends to reconstruct the main experiments of the acoustics musical history, which are responsible for the consolidation of the theory that is currently known, evidencing the points of the importance on the experimental verification in the production of the acoustic knowledge, in the history of science. In this direction, it is extremely important that this research provides theoretical subsidies to the implementation of a transition between a centered musical science and an arithmetical dogmatism for a musical science which has the experimental verification as a relevant criteria of falsifiability of its theories. In doing so, this project intends to present the didatic exposition that will be carried out in the museum \"Estação Ciência\", reproducing, in writing, its structure, experiments and panels that aim to clarify emergent acoustic concepts in Old Greece and its transformations throughout the Scientific Revolution.

L’expression « physiologie du travail » apparaît dans les Congrès d’Hygiène et de Démographie de 1900 à 1904 pour désigner un nouveau programme de recherches – que quelques savants et hommes politiques appellent de leurs voeux – appliquant les méthodes et modèles de la physiologie fondamentale à l’étude du corps au travail dans différentes professions déterminées. Se dotant en 1913 d’un premier laboratoire public officiel, la « physiologie du travail professionnel » tente d’initier – à travers la diffusion d’études de cas et la publication de textes programmatiques – une vaste entreprise d’analyse scientifique du travail humain censée permettre de rationaliser la législation, d’arbitrer les conflits et d’optimiser l’organisation du travail. Développées d’abord indépendamment des travaux de Taylor, ces recherches vont pourtant (dès le début des années 1910) se présenter comme une amélioration du taylorisme – entérinant ses grands principes mais adaptant ses applications aux spécificités de l’organisme humain.Prenant ce "moment 1900" comme point de départ de la réflexion, le présent travail cherche à réinscrire les débats qui ont agité la constitution de cette nouvelle discipline dans la perspective de leur histoire longue – car le corps au travail n’attend pas le tournant du XXe siècle pour faire l’objet d’études scientifiques. L’hypothèse mise à l’épreuve est alors la suivante : le problème épistémologique essentiel qui se joue dans l’idée de « physiologie du travail » tient à ce que des spécialistes du fonctionnement organique vont subitement proposer d’analyser la façon dont les travailleurs utilisent leurs corps, et prétendre ainsi évaluer et optimiser cet usage à l’aune de critères directement issus d’une modélisation physiologique. Pour repérer les origines et suivre les évolutions de cette idée originale à travers les XVIIe, XVIIIe et XIXe siècles, ons’est donc proposé d’interroger les glissements – dans quelques grandes études de cas historiques d’analyse du travail humain – entre l’intérieur et l’extérieur du corps opérés par une modélisation tendue entre désir de comprendre et volonté de réformer.Si le matériau analysé est de nature historique, l’angle d’analyse est – par contre – une question de type philosophique : qu'est-ce que les motivations et les difficultés des « physiologistes du travail » nous apprennent quant à la volonté de dicter aux êtres humains le « bon usage » de leur propre corps – pour leur bien, et au nom d'une connaissance experte de son fonctionnement ? La problématique du présent travail cherchera en effet à comprendre pourquoi ces physiologistes d'un genre nouveau ont prétendu assigner au corps des ouvriers un mode d'emploi – et surtout pourquoi une telle prétention a finalement échoué, ouvrant la voie à une nouvelle façon d'aborder le problème dans ce qui deviendra à terme l'ergonomie. / The phrase “work physiology” (referring to professional work) appeared during the International Hygiene and Demography Congresses between 1900 and 1904. It was first used to call for a brand new research program applying the methods and results of experimental physiology to the study of the body at work in several definite occupations. Creating its first official state-funded laboratory in 1913, this “professional work physiology” tried to launch – by means of well publicized case studies and declarations – a large-scale scientific enterprise for the scientific analysis of human work. The self-proclaimed aim was to rationalize legislation regarding fatigue, settle arguments (between employers and employees) on scientific grounds, and most of all optimize the organization of work. This specific kind of “work physiology” developed t first without the knowledge of Taylor’s research, but as soon as the beginning of the 1910’s, “work physiologists” started announcing that their own studies tended to improve taylorism – as they confirmed its principles while adapting its applications to the specificities of the living organism.This thesis takes the “1900 period” as a starting point in order to show how the scientific debates resulting in the formation of “work physiology” actually have roots in distant history – for the working body has been an object for scientific study since at least the late 17th century. Our hypothesis is as follows: the formation of a “work physiology” raises an important epistemological issue, namely that experts in the organic functioning suddenly analyze the way workers are using their own bodies. Thus, while changing their object, scientists claim that it is possible to evaluate and optimize this use of one’s body from a purely physiological standpoint. This thesis tries to shed light on the source and the evolution of this peculiar idea, throughout the 17th, 18th and 19th century. Focusing on a few famous cases studies in the scientific analysis of human work, we try to show how the modeling practices tend to mix statements about what happens inside the body with what is at stake outside the body, in the real-world work situation.While the facts analyzed here are historical in nature, the question asked to carry out the analysis is philosophical in nature: what can we learn from the motives developed by and the difficulties encountered by these physiologists of a new kind, regarding the claim to dictate a “correct use” of the body solely based on physiological knowledge ? The issue that this dissertation tries to raise boils down to this question: can one assign something like an instruction manual to the living body? – a question fully renewed in the fifties and sixties by the newly formed ergonomics.

This thesis focuses on the trajectory of the biomedical concept of virulence from 1880 until the present. Following the concept across disciplinary boundaries, from a longue durée history perspective, it explores how virulence was shaped through two distinct, although sometimes overlapping, “styles of reasoning”. Located at the intersection of several distinct research domains in biology and medicine, the concept of virulence provides, in addition, a window into the complex and changing relations between evolutionary biology and the health sciences (broadly construed) over the past two centuries. Moving back and forth between field experiments and the laboratory, this work examines, through the lens of historical epistemology, the emergence of what I call the molecular and the ecological styles, and their respective conceptual practices. It focuses on the ways in which these styles operationalize the distinction between virulent or avirulent organisms in sometimes opposite sense: Whereas in the molecular (or endogenous) style the expression of virulence is explained by properties of internal structures of the infectious agent (e.g. polysaccharide capsule, virulence gene, or pathogenicity island), the concept of virulence in the ecological (or exogenous) style reflects, in contrast, either a lack of adaptation between two species (avirulence hypothesis) or the existence of one or more ecological compromises between, say, the mode of transmission of a pathogen and its host’s recovery rate (trade-off model). Both styles can be said to originate in the medical bacteriology of the late-nineteenth century, but while the former grew mostly out of the work of Louis Pasteur and Robert Koch in Europe, the latter was primarily shaped by Theobald Smith in the United States. Nearly a century later, the introduction of the category of emerging infectious disease within public health discourses in the mid-1990s facilitated a rapprochement between the two styles that had, so far, remained apart. Employing the 1918–1919 influenza pandemic as an example in which to illustrate the trajectory of the molecular and the ecological approaches, the diversity of explanatory schemes developed to account for the pandemic’s exceptional virulence points toward an unresolved, and yet productive, epistemic tension between the two styles, on the one hand, and the intrinsic polarity of the concept of virulence itself, on the other.

Ma recherche a pour but de faire le point sur les derniers développements de l’historical epistemology, modalité d’enquête de la connaissance qui a émergée au cours du XX siècle au sein de l’épistémologie française et qui reste actuellement active dans une variété de formes. En dépit de son succès auprès de nombreux auteurs contemporains, l’épistémologie historique ne bénéficie encore d’aucune systématisation ni d’aucune liste d’auteurs et d’ouvrages canoniques. Mon travail de thèse se propose de traiter directement la question même de la légitimité et de l’originalité de ce type d’épistémologie en discutant sa nature, sa méthodologie et son unité. En analysant les ouvrages les plus importants dans ce domaine, j’accorderai un rôle central d’un coté à Michel Foucault et de l’autre à Ian Hacking, qui, à maintes égards, ont entretenu des rapports complexes, controversés, et pourtant révélateurs, avec l’épistémologie historique. Les deux phases de l’épistémologie historique, l’une « originaire » et l’autre « contemporaine », seront analysées dans un rapport biunivoque, dans un souci de clarification réciproque. Le développement à l’étranger de l’épistémologie historique dans sa phase contemporaine a créé une sorte de vide et une perte d’intérêt étonnante dans son lieu de naissance. La reconnexion de ce type d’épistémologie au cadre philosophique originel de son émergence représente l’occasion de ré-ouvrir le débat en France. / What is historical epistemology? Why does this field, despite its current proliferation,seem to be permanently haunted by questions relative to its nature, limits and ultimatetasks? What kind of historicization is at stake in this sort of inquiry? What is the relationbetween contemporary historical epistemology, as it is practiced by a growing number ofEnglish-speaking historians and philosophers of science, and the French “tradition” ofépistémologie historique? To address these questions, my research aims to provide arecursive analysis demonstrating how the two phases of historical epistemology, the“classical” and the “contemporary”, can clarify each other. In this process, the“archaeological method” of Michel Foucault, which draws on and transforms fundamentalinsights by Gaston Bachelard and Georges Canguilhem, will be shown to exert an enduringinfluence on the field, especially through Ian Hacking and his philosophical cum historicalanalyses of probability. / Che cos’è l’epistemologia storica? Perchè questo campo, nonostante la sua proliferazione attuale, sembra essere permanentemente minacciato da questioni relative alla sua natura, ai suoi limiti e ai suoi obiettivi ultimi? Che tipo di storicizzazione caratterizza questo tipo di indagine? Qual è la relazione tra l’epistemologia storica contemporanea, come è praticata da un numero crescente di storici e filosofi della scienza di lingua inglese, e la tradizione francese dell’épistémologie historique? Per affrontare tali questioni, la mia ricerca intende fornire un’analisi ricorsiva che dimostri come le due fasi dell’epistemologia storica, quella “classica” e quella “contemporanea”, possono chiarificarsi reciprocamente. In questo processo, il “metodo archeologico” di Foucault, che trae spunto da e trasforma intuizioni fondamentali di Gaston Bachelard e Georges Canguilhem, sarà mostrato nella sua influenza su questo campo di indagine, specialmente attraverso Ian Hacking e le sue analisi storico-filosofiche della probabilità.

History is descriptive. Epistemology is conceived as normative. It appears, then, that a historical approach to epistemology, like historical epistemology, might not be epistemically normative. In our context here, epistemology is not a systematic theory of knowledge, truth, or justification. In this thesis I approach epistemic justification through the vantage point of practice of science. Practice is about reasoning. Reasoning, conceived as the human propensity to order perceptions, beliefs, memories, etc., in ways that permit us to have understanding, is not only about thinking. Reasoning has to do with our actions, too: In the ordering of reasoning we take into account the desires of ourselves and others. Reasoning has to do with tinkering with stuff, physical or abstract. Practice is primarily about skills. Practices are not mere groping. They have a form. Performing according to a practice is an activity with a lot of plasticity. The skilled performer retains the form of the practice in many different situations. Finally, practices are not static in time. Practices develop. People try new things, some of which may work out, others not. The technology involved in how to go about doing things in a particular practice changes, and the concepts concerning understanding what one is doing also may change. This is the point where history enters the picture. In this thesis I explore the interactions between history, reasoning, and skills from the viewpoint of a particular type of epistemic justification: a priori justification. An a priori justified proposition is a proposition which is evident independent of experience. Such propositions are self-evident. We will make sense of a priori justification in a context of regarding science as practice, so that we will be able to demonstrate that the latter accommodates the normative character of science.

On prend pour point de départ le constat d'une résistance dans la réception marxiste française de la thèse féministe de Judith Butler portant sur la construction discursive du «sexe» par le «genre». L'antagonisme apparent du matérialisme et du constructivisme, révélé par la réception française de Trouble dans le genre, invite à chercher, en amont, une solution matérialiste au problème épistémologique de la construction conceptuelle du donné. En remontant à la source de Marx, on peut montrer que sa pensée a nourri, chez Althusser et Foucault, une approche matérialiste du discours qu'on peut qualifier de constructiviste. Au prisme de l'épistémologie historique de Canguilhem, se dessinent des parentés entre Althusser et Foucault qui donnent une postérité inédite à Marx: l'exploration de deux figures du «matérialisme discursif» dans l'archéologie foucaldienne et l'épistémologie althussérienne, permet de rendre caduques les objections empiristes à l'idée d'une construction discursive du« sexe». L'objectif est de proposer une articulation entre le matérialisme marxiste et la pensée queer, en mettant au jour une tradition de pensée qui croise les apports de l'épistémologie historique et du matérialisme, et prend au sérieux la production de la nature et du corps par le discours. Il s'agit de donner à la thèse de Butler les conditions de son audibilité matérialiste et de déterminer en retour la fécondité de sa mise en question du donné pour le marxisme. / This analysis starts by pointing out a reluctance in the French Marxist reception of Judith Butler's feminist theories, mainly those regarding the discursive construction of « sex » by «gender». This apparent conflict between materialism and constructivism encourages us to look upstream for a materialistic solution to the epistemological issue of the conceptual construction of «facts». By getting back at the root of Marx, one can indeed show that his thought has provided input into Althusser's and Foucault's reflections for the development of a materialistic approach of discourse, which may be qualified as contructivist. In the light of Canguilhem's historical epistemology, some philosophical kinship between Althusser and Foucault takes shape, which provides a previously unseen posterity to Marx : the examination of two features of «discursive materialism» in Foucault's archeology and in Althusser's epistemology enables to make null and void the empiricist objections at the idea of a discursive construction of «sex». The goal is to pro vide a philosophical junction between Marxist materialism and queer theory, by highlighting a tradition of thought which combines the contributions of historical epistemology and materialism, and which takes seriously into consideration the production of nature and body by discourse. The goal is to provide Butler's theory with the means to be heard as a materialistic account, and in return to specify for marxism what it might gain when this theory challenges the given facts.

En prenant le contre-pied des méthodes généralisées et universalisantes d’évaluation mondiale des institutions de la science, la présente thèse décrit les savoirs générés par le discours universitaire au moment de leur mise à l’épreuve de validation par des instances d’évaluation d’un espace localisé. Le cadre d’observation est le système d’évaluation en vigueur au Cameroun qui sert de dispositif de promotion sociale des enseignants-chercheurs, et de légitimation du travail universitaire. Le décryptage des formes de savoirs produits en situation d’évaluation endogène prend appui sur l’épistémologie historique et l’archéologie foucaldienne des discours. Les résultats de l’analyse montrent que le savoir produit, s’inscrivant dans une temporalité discursive est anonyme et marqué historiquement, culturellement et géographiquement. Ce savoir appartient en outre à un réseau de discours qui dépasse la seule sphère des universités et des disciplines. Les mécanismes et stratégies d’élaboration des savoirs sont soumis à des règles et à des normes qui elles-mêmes produisent de manière permanente des formes de pouvoir. Les référents théoriques et méthodologiques mobilisés dans ce travail participent à l’enrichissement des cadres de référence traditionnels des sciences de l’information et de la communication. / In addition to the general and universal evaluation methods of scientific instituions, this thesis describes knowledge generated by university discourse during validation by local authorities. The framework of experience is the evaluation system in force in Cameroon which serves as social promotion for university lecturers and researchers and legitimizes university work. Deciphering forms of knowledge produced in an endogenous evaluation system is based on historical epistemology and Foucaldian archeology of discourse. The results of the analysis show that knowledge produced falls within the purview of discursive temporality and is anonymous and geographically, culturally and historically marked. It belongs moreover to a network of discourse which goes beyond the lone sphere of universities and disciplines. Knowledge generation mechanisms and strategies are subject to rules and standards which themselves permanently produce forms of power. The theoretical and methodological referents mobilised in this work contribute to the development of traditional frames of information and communication sciences

Dans Naissance de la clinique, Michel Foucault mit en évidence l’émergence au XIXe siècle d’un regard médical qui, en faisant taire la théorie au lit du malade, tâche de parler la langue étrangère de la maladie dans la profondeur des tissus. En opposition aux nosographies essentialistes du XVIIIe siècle, une forme de nominalisme médical apparaît progressivement à travers le développement de l’anatomo-pathologie. Cette médecine clinique est parcourue par un concept souvent oublié qui se trame, pourtant, dans l’ombre de son savoir et préfigure son dépassement. Il s’agit du concept de « probabilité ». Bien que celui-ci s’inscrit dans la clinique, l’application du calcul de probabilités ne parvient pas à s’y intégrer. Le XIXe siècle sera le théâtre d’un véritable conflit sur la conjecture qui oppose « les numéristes » et les cliniciens d’obédience hippocratique. L’orthodoxie de l’Ecole de Paris se trouve confrontée à l’émergence de la méthode numérique. La dispute théorique qui en résulte problématise l’application du calcul de probabilités en la médecine : du probable peut-on connaître autre chose que du probable ? Durant tout le XIXe siècle, on s’accorde à rejeter épistémologiquement cette méthode. Elle ne cadre pas avec la positivité des sciences médicales. Ce sera l’hygiène publique qui en fera usage pour pallier à l’inanité clinique dans le traitement des épidémies, des endémies et des épizooties. Cette rencontre conflictuelle de l’individuel et du collectif dans le médical fera naître une nouvelle forme de nosologie au XXe siècle. Il s’agit d’en comprendre l’émergence. / In The Birth of The Clinic, Michel Foucault highlights the emergence of a medical gaze in the 19th-century that – by vanishing the theory at the patient's bedside – tries to speak the foreign language of the disease in the depth of organic tissues. With the development of anatomo-pathology, a form of medical nominalism progressively appears in opposition to the essentialist nosography of the 18th-century. This clinical medicine is shot-through by a concept often forgotten that is framed, however in the shadow of clinical medical knowledge and that prefigures its disappearance. This is the concept of "probability". Even though this concept is part of clinical medicine, the application of probability calculation fails to be part of medical knowledge. The 19th-century was the scene of a conflict over numerical conjecture that opposes "Numerists" and Hippocratic’s Clinician. The Ecole de Paris’s orthodoxy was then confronted with the emergence of the numerical method. The theoretical dispute that results from the application of the calculation of probabilities in medicine gives rise to this question: from what is only probable, can we know anything else than what is probable? Throughout the 19th-century, the numerical method is rejected on epistemological grounds. It is held not to fit with the positivity of medical science. In the treatment of epidemics, endemic diseases, and epizootics, public health services make use of it still. This confrontation between the individual and the collective in medicine gives rise to a new form of nosology in the 20th-century.
