Philosophe majeur de notre epoque, Henri Maldiney a elabore une phenomenologie de l'existence centree sur l'Ouvert. Preconisant un - retour aux choses memes -, il refute radicalement la separation instauree entre sujet et objet, insistant sur l'experience de la rencontre comme signifiance insignifiable, transpossibilite et transpassibilite, recueil et deploiement. a partir notamment de Binswanger, Straus, Freud, Szondi, Heidegger et plus largement des textes classiques grecs, allemands, chinois, accordant une importance toute particuliere a l'art, il a contribue de maniere decisive a (...) une philosophie du sentir, du rythme et de l'avenement. Lors du colloque de Cerisy, qui a reuni chercheurs, praticiens et artistes, chacun s'est mis a l'epreuve de cette oeuvre magistrale. Les contributions rassemblees ici manifestent l'evolution et l'impact de cette pensee fondamentale pour le XXIe siecle.". (shrink)

The relativistic revolution led to varieties of neo-Kantianism in which constitutive principles define the object of scientific knowledge in a domain-dependent and historically mutable manner. These principles are a priori insofar as they are necessary premises for the formulation of empirical laws in a given domain, but they lack the self-evidence of Kant’s a priori and they cannot be identified without prior knowledge of the theory they purport to frame. In contrast, the rationalist endeavors of a few masters of theoretical (...) physics have led to comprehensibility conditions that are easily admitted in a given domain and yet suffice to generate the theory of this domain. The purpose of this essay is to compare these two kinds of relativized a priori, to discuss the nature of the comprehensibility conditions, and to demonstrate their effectiveness in a modular conception of physical theories.

In 1887 Helmholtz discussed the foundations of measurement in science as a last contribution to his philosophy of knowledge. This essay borrowed from earlier debates on the foundations of mathematics, on the possibility of quantitative psychology, and on the meaning of temperature measurement. Late nineteenth-century scrutinisers of the foundations of mathematics made little of Helmholtz’s essay. Yet it inspired two mathematicians with an eye on physics, and a few philosopher-physicists. The aim of the present paper is to situate Helmholtz’s contribution (...) in this complex array of nineteenth-century philosophies of number, quantity, and measurement.Author Keywords: Helmholtz; Measurement; Arithmetic; P. Du Bois-Reymond; H. and R. Grassmann; J. von Kries. (shrink)

Research on the influence of industry on chemical regulation has mostly been conducted within the framework of the production of ignorance. This special issue extends this research by looking at how industry asserts its interests––not just in the scientific sphere but also at other stages of policy-making and regulatory process––with a specific focus on the types of tools or instruments industry has used. Bringing together sociologists and historians specialized in Science and Technology Studies, the articles of the special issue study (...) the arenas in which instruments and practical guidelines for public policy are negotiated or used. The aim is to observe the devices in the making or in action, from the selection of actors to the production of thresholds, criteria, and other technical regulations. The introduction highlights how industry influence on expertise and regulation is undoubtedly far more pervasive and multifarious than has been conceptualized to date by social scientists. Putting this issue back at the heart of both the STS and social sciences research agendas is increasingly urgent and could lead to new inquiries able to highlight these logics even more widely, using fresh empirical examples.

Cet article examine le traitement donné par Descartes et certains de ses successeurs d’une question classique, quoique peu étudiée, celle de savoir si l’on peut penser plusieurs choses à la fois. Le thème d’une saisie simultanée est central dans la théorie cartésienne de la connaissance, en particulier dans les Regulæ, où il s’appuie sur le recours à une attention divisée. Restreignant ce pouvoir à la seule imagination, Clauberg voit dans le corps vivant le paradigme de la simultanéité. Spinoza offre quant (...) à lui un point de vue synthétique : la simultanéité dans le corps et l’esprit sont des expressions de la puissance individuelle et de son progrès. L’attention n’est plus comme chez Descartes une condition de la simultanéité intellectuelle, mais un obstacle qu’il s’agit de surmonter pour comprendre plus et mieux. (shrink)

In French mechanical treatises of the nineteenth century, Newton’s second law of motion was frequently derived from a relativity principle. The origin of this trend is found in ingenious arguments by Huygens and Laplace, with intermediate contributions by Euler and d’Alembert. The derivations initially relied on Galilean relativity and impulsive forces. After Bélanger’s Cours de mécanique of 1847, they employed continuous forces and a stronger relativity with respect to any commonly impressed motion. The name “principle of relative motions” and the (...) very idea of using this principle as a constructive tool were born in this context. The consequences of Poincaré’s and Einstein’s awareness of this approach are analyzed. Lastly, the legitimacy and significance of a relativity-based derivation of Newton’s second law are briefly discussed in a more philosophical vein. (shrink)

We study the class of elementary submodels of a large superstable homogeneous model. We introduce a rank which is bounded in the superstable case, and use it to define a dependence relation which shares many (but not all) of the properties of forking in the first order case. The main difference is that we do not have extension over all sets. We also present an example of Shelah showing that extension over all sets may not hold for any dependence relation (...) for superstable homogeneous models. (shrink)

This essay discusses attempts that have been made to explain the striking similarities between two theories propounded in 1905 by Albert Einstein and Henri Poincaré without any mutual reference.

When Henri Poincaré reviewed the then competing theories of electrodynamics in the 1890s, he required their compatibility with two principles of mechanical origin—the reaction principle and the relativity principle. Historians of relativity theory have usually focused on the relativity principle and neglected or misinterpreted Poincaré’s concern with the reaction principle. In particular, most of them have interpreted his crucial article of 1900 on “Lorentz’s theory and the principle of reaction” as an attempt to save this principle by assuming an electromagnetic (...) momentum in addition to the momentum of matter. The purpose of this article is to dismiss this interpretation and show that Poincaré had the opposite intention as he spelled out the paradoxical consequences of Lorentz’s violation of the reaction principle. In doing so, he formally introduced a quantity that could later be interpreted as a genuine electromagnetic momentum, developed a fundamentally new understanding of Lorentz’s transformations in relation with the relativity principle and identified the paradoxes that Einstein would later solve by assuming the inertia of energy.

L’expression équilibre naturel est largement utilisée dans les médias et par les militants écologistes pour sensibiliser le grand public aux conséquences néfastes des activités humaines sur l’environnement. Pourtant, alors qu’elle était relativement plébiscitée par les scientifiques au xixe et au début du xxe siècle, la quasi-totalité des écologues n’emploie plus cette expression. Dans cet article, nous visons à montrer que cette expression n’a pas été abandonnée à cause d’une réfutation de l’idée qu’elle recouvrait mais à cause d’une tombée en désuétude. (...) Nous avançons deux causes possibles à cette tombée en désuétude et nous défendons que les termes actuels de stabilité et de résilience renvoient à la même idée qui persiste et se précise. (shrink)

This book builds on recent scholarship highlighted in the edited collections, Philosophie, histoire, biologie: mélanges offerts à Jean Gayon (Merlin & Huneman, 2018) and Knowledge of Life Today (Gayon & Petit 2018/2019). While honoring the career and the thought of Jean Gayon (1949-2018), this book showcases the continued relevance of Gayon’s interdisciplinary work and illustrates his central place in the community of historians and philosophers of the life sciences. Chapters in this book address Jean Gayon’s intellectual trajectory from historical epistemology (...) to the philosophy of biology, the nature and scope of his philosophical approach to the history of science, and his unique contributions to the history and epistemology of biological concepts and theories. Drawing on published and unpublished sources, the book explores some of Gayon’s most significant contributions to the philosophy, history, and social studies of biology. (shrink)

Dans les nations industrialisées, les goûts des individus sont désormais employés à doper la consommation. L'industrialisation de la jouissance privilégie le superflu au nécessaire, la sensibilité à la raison, la séduction à la faculté de juger. Pourtant, avec l'exploitation du goût, le capitalisme est loin d'avoir découvert une terre inconnue. A l'âge classique, la noblesse de cour cultivait un style de vie commandé par les loisirs et le goût, tout en faisant du bon goût un critère de distinction et de (...) promotion individuelle. Ces relations de compétition entre courtisans ont-elles été les premières notes en prélude au libéralisme? Si l'improductivité, au sens économique, a pu constituer une valeur fondatrice du goût, comment l'industrie a-t-elle pu transformer le goût en moteur économique de la consommation? Le devenir esthétique du capitalisme repose sur la captation et la conversion de ce qu'il aurait de plus individuel en valeurs mesurables, échangeables et massifiables, susceptibles de coloniser les moindres recoins de l'existence et de al culture. L'ouvrage montre que les enjeux du capitalisme esthétique excèdent le territoire angélique des agréments : les batailles esthétiques sont au cœur d'une guerre économique pour le contrôle des émotions et des affections.

Au-delà de ces significations spontanées, la notion a pourtant une portée philosophique plus profonde et plus générale, qui se révèle à travers une réflexion radicale sur les deux manières que nous avons de définir l'homme : par sa nature intime et par le rapport à l'autre. Or, dira l'auteur, ces deux inventions modernes sont à la fois des tentatives de négation de la destruction inhérente à l'existence et son exacerbation. C'est cette logique de l'existence qu'il s'agit de faire apparaître ici (...) dans son implacable fatalité, sans le cataplasme d'une pensée de l'espoir et sans promesses de bonheur. (shrink)

Cet article veut démontrer l’importance de la temporalité dans le champ des études queer. Notre objectif premier est de souligner que le concept de queer se révèle être fondamentalement un concept temporel qui se déploie de manière dynamique et transitoire. Par l’entremise du concept de résistance foucaldienne, nous insistons pour montrer qu’au cœur de la temporalité queer s’expose aussi bien une négativité — une critique de la temporalité hétéronormative — qu’une positivité — la création de nouvelles manières de vivre temporellement.

The aim of this paper is to give a critical discussion of Sartre’s concept of sexual desire and its relation to self-identity and freedom. Why Sartre? Sartre is one of very few philosophers who offers a systematic account of sexual desire. He has influenced eminent philosophical concepts of sexual desire held by, for instance, de Beauvoir, Lacan, Foucault, Levinas, Irigaray and Butler, but not much is written about his own notion of sexual desire. This alone is reason to explore Sartre’s (...) view. What makes his view of sexual desire particularly interesting is that it is framed by his theory of freedom. Sartre offers the original, radical notion that freedom is absolute. Because consciousness is never self-identical, he argues, human identity is not fixed. Instead, we are consequently nothing else but what we keep desiring to make of ourselves. He concludes that we are always free to choose our drives and desires, even what seem to be our most enslaving, natural sexual instincts. The question raised in this article, however, concerns what the nature of sexual desire is and how free we really are to choose our sexual desires. I first contextualise Sartre’s view of sexual desire within his notion of desire in general and its relation to instinct, drive, consciousness, freedom and identity. Then, I give a detailed discussion of his analysis of sexual desire, its relation to freedom, and, what Sartre calls its failures. Finally, I discuss a critique of, and alternative to, Sartre’s theory of sexual desire from the perspective of my own notion of heteronomous and autonomous desire and freedom. (shrink)

An interesting positive theory is the GPK theory. The models of this theory include all hyperuniverses (see [5] for a definition of these ones). Here we add a form of the axiom of infinity and a new scheme to obtain GPK∞+. We show that in these conditions, we can interprete the Kelley‐Morse theory (KM) in GPK∞+ (Theorem 3.7). This needs a preliminary property which give an interpretation of the Zermelo‐Fraenkel set theory (ZF) in GPK∞+. We also see what happens in (...) the original GPK theory. Before doing this, we first need to study the basic properties of the theory. This is done in the first two sections. (shrink)

Analogies between hearing and seeing already existed in ancient Greek theories of perception. The present paper follows the evolution of such analogies until the rise of 17th century optics, with due regard to the diversity of their origins and nature but with particular emphasis on their bearing on the physical concepts of light and sound. Whereas the old Greek analogies were only side effects of the unifying concepts of perception, the analogies of the 17th century played an important role in (...) constructing optical theories by imitation of acoustic theories, or vice versa. This transition depended on several factors including the changing relations between optics, music, mathematics, and physics, the diversity of early modern concepts of sound, and the rise of a new physics based on experimentation and mechanical explanation.

We review the history of the philosophy of fondue since Aristotle so as to arrive at the formulation of the paradox of Swiss fondue. Either the wine and the cheese cease to exist (Buridan), but then the fondue is not really a mixture of wine and cheese. Or the wine and the cheese continue to exist. If they do, then either they continue to exist in different places (the chemists), but then a fondue can never be perfectly homogenous (it is (...) a French fondue). Or the wine and the cheese continue to exist in the same place (the Stoïcs), but then wine and cheese have to be, oddly, penetrable and spatially expansible. Aristote attempted to solve this paradox by arguing that the cheese and wine continue to exist, but only potentially in the fondue. We sketch an alternative answer. The wine and the cheese continue to exist, but only non-spatially in the fondue. Wine and cheese, once mixed, become non-spatial constituents of the fondue, a bit like character traits are non-spatial constituents of persons. The wine and the cheese are in the fondue, but only the fondue is there in the fondue pot. (shrink)

A slight modification of Helmholtz’s metrical approach to the foundations of geometry leads to the locally Euclidian character of space without restriction of the curvature. A bolder generalization involving time measurement leads to the locally Minkowskian character of spacetime. Some philosophical consequences of these results are drawn.Keywords: Hermann Helmholtz; Space; Time; Spacetime.

Dans les Cours d'Esthétique, qu'il prononce à Berlin entre 1820 et 1829, Hegel propose une théorie de la musique et analyse le rapport de celle-ci avec les autres arts dans l'ensemble du système philosophique. Mais comment le philosophe, qui n'est pas connaisseur, peut-il penser la musique de son temps? Sur quelle base se construit la réflexion? Et comment la reconstituer scientifiquement à partir des différentes sources? Le présent ouvrage apporte une réponse à ces questions en replaçant le discours hégélien dans (...) l'arrière-plan socio-historique de la vie musicale contemporaine, et en reconstituant, pour la première fois, la théorie de Hegel à partir des manuscrits inédits des différents cours. La spéculation apparaît alors dans toute son originalité, comme le prolongement des multiples expériences faites au théâtre et au concert. La conception de la musique comme manifestation de l'esprit absolu se vérifie alors dans l'expérience la plus concrète. (shrink)

To be optimistic, it is standardly assumed, is to have positive expectations. I here argue that this definition is correct but captures only one variety of optimism – here called factual optimism. It leaves out two other important varieties of optimism. The first – focal optimism – corresponds to the idea of seeing the glass half full. The second – axiological optimism – consists in the view that good is stronger than bad. Those three varieties of optimism are irreducible to (...) each other and do not belong to a common kind. I define each of these, characterize their respective correctness conditions, and contrast hope with optimism. (shrink)

Samuel Johnson claimed to have refuted Berkeley by kicking a stone. It is generally thought that Johnson misses the point of Berkeley's immaterialism for a rather obvious reason: Berkeley never denied that the stone feels solid, but only that the stone could exist independently of any mind. I argue that Johnson was on the right track. On my interpretation, Johnson’s idea is that because the stone feels to resist our effort, the stone seems to have causal powers. But if appearances (...) are to be taken at face value, as Berkeley insists, then the stone has causal powers. I argue that such causal powers threaten not only Berkeley’s view that only minds are active, but also, and more fundamentally, his central claim that sensible things depend on perception. (shrink)

Can one refute Berkeleyan phenomenalism by arguing that sensory objects seem mind-independent, and that, according to Berkeley, experience is to be taken at face value? Relying on Mackie’s recent discussion of the issue, I argue, first, that phenomenalism cannot be straightforwardly refuted by relying on perceptual or bodily experience of mind-independence together with the truthfulness of experience. However, I maintain, second that phenomenalism can be indirectly refuted by appealing to the bodily experience of resistance. Such experience presents us with the (...) causal activity of the resisting physical object. If experience is truthful, as the phenomenalist has it, physical objects are causally active. But then their effects no longer depend on our perceiving them, on pain of overdetermination. (shrink)

Phenomenology is an emerging field within the broader domain of African and Africana philosophy. The phenomenological method, with its various approaches to studying the meaning of lived experience, is at the core of the thought of African philosophers such as Paulin Hountondji, Dismas A. Masolo, Achille Mbembe, Mabogo More, Tsenay Serequeberhan, Noel Chabani Manganyi, and proponents of Africana Philosophy such as WEB Du Bois, Frantz Fanon, Lucius Outlaw, Lewis Gordon, George Yancy, and Linda Martin Alcoff. Technically, the term “African phenomenology” (...) is not used as widely, or introduced as systematically, as Africana phenomenology. The aim of this chapter is to introduce some of the central issues and theorists of the field of African phenomenology. As the subtitle of this chapter indicates, its scope is limited to what one may call introductory perspectives in African phenomenology. The idea is to outline for further investigation some thematically related contributions to African phenomenology with specific reference to the grounding work of Paulin Hountondji as related to works of Kwasi Wiredu and Dismas A. Masolo. Hountondji’s critical adoption of Husserl’s classic phenomenological approach offers a broad, foundational scope, which makes it particularly suitable for a basic introduction to African phenomenology.

Hans KELSEN, le plus célèbre philosophe du droit issu du rang des juristes, est surtout connu pour avoir fondé une école juridique (l'Ecole de Vienne) qui radicalise la doctrine du positivisme juridique. Il a défendu, sa vie durant, une conception normativiste du droit et la thèse d'une stricte séparation entre le droit et la science du droit. Si l'on connaît bien en France son ouvrage programmatique sur la Théorie pure du droit, dans sa deuxième édition traduite par Charles Eisenmann, on (...) sait au moins que cette seconde édition, publiée en 1960, n'est pas l'expression définitive de sa pensée. La traduction de la Théorie générale des normes, qui est un ouvrage posthume et inachevé, donne au lecteur français l'occasion de découvrir cette pensée dans ses derniers développements qui rompent en partie avec ceux de l'œuvre précédente. Le Maître viennois y poursuit l'analyse de la norme juridique, entamée dans la Théorie pure du droit, mais il l'approfondit sur certains points et l'infléchit sur d'autres. Il introduit ainsi de nouvelles réflexions sur la signification de la norme et sur ses fonctions, sur l'application et l'interprétation de la norme et également sur le rapport entre la norme et le langage, insistant notamment sur la distinction entre la norme et l'énoncé sur la norme. Par ailleurs, il considère la religion et le droit comme deux ordres normatifs similaires, ce qui le conduit à proposer une théorie vraiment " générale " des normes et non pas seulement une théorie juridique des normes. Il avance une nouvelle interprétation de la norme fondamentale en recourant à l'idée de fiction juridique. Enfin, dans la dernière partie du livre, Kelsen donne le dernier état de sa pensée sur le problème majeur de l'application de la logique au droit. Rompant avec son logicisme antérieur, il nie l'existence d'une logique spécifique au droit et conteste l'application de la logique syllogistique au processus d'application du droit, renouant ainsi avec un volontarisme juridique qu'il avait rejeté au début de son œuvre. Dans cet ouvrage, sous couvert de bâtir une théorie générale des normes, Kelsen construit une théorie de l'interprétation des normes. Il propose donc une herméneutique juridique originale qui intéressera tous ceux qui étudient les sciences normatives (juristes, mais aussi théologiens et spécialistes de l'éthique). Il engage un dialogue avec les représentants anglo-américains de la philosophie du droit, de l'éthique ou de la logique, et il renoue le dialogue avec les auteurs influents à Vienne au début du siècle.

In African Philosophy and Enactivist Cognition: The Space of Thought (2023), Bruce B. Janz introduces what he calls an enactivist African philosophy. The book makes a significant contribution to African philosophy as no other work has yet made the connection between African philosophy and enactivism. This article’s aim is to give a critical response to the book. It starts with some background by connecting Enactivist Cognition with Janz’s earlier Philosophy in an African Place (2009). This is followed by a brief (...) discussion of his introduction to enactivist African philosophy and its connection to texts in African philosophy. The article closes with a discussion of some issues that Enactivist Cognition raises. (shrink)

This chapter has three sections. The first introduces Brentano’s view of sensations by presenting the intentional features of sensations irreducible to features of the sensory objects. The second presents Brentano’s view of sensory objects —which include sensory qualities— and the features of sensations that such objects allow to explain, such as their intensity. The third section presents Brentano’s approach to sensory pleasures and pains, which combines both appeal to specific modes of reference and to specific sensory qualities.

Urban agriculture is an important source of food and income throughout Africa. The majority of cultivators on the continent are women who use urban agriculture to provide for their family. Much research on urban agriculture in Africa focuses on the material benefits of urban agriculture for women, but a smaller body of literature considers its social and psychological empowering effects. The present study seeks to contribute to this debate by looking at the ways in which urban agriculture empowers women on (...) the Cape Flats, a region of Cape Town where urban agriculture is supported by nongovernmental organisations. Based on interviews with cultivators, the findings show that NGO-run urban agriculture projects not only aid food security, but also help women to develop supportive networks that unlock benefits across the personal, social and economic spectrum.

Touch seems to enjoy some epistemic advantage over the other senses when it comes to attest to the reality of external objects. The question is not whether only what appears in tactile experiences is real. It is that only whether appears in tactile experiences feels real to the subject. In this chapter we first clarify how exactly the rather vague idea of an epistemic advantage of touch over the other senses should be interpreted. We then defend a “muscular thesis”, to (...) the effect that only the experience of resistance to our motor efforts, as it arises in effortful touch, presents us with the independent existence of some causally empowered object. We finally consider whether this muscular thesis applies to the perception of our own body. (shrink)

In Why pains are not mental objects Guy Douglasrightly argues that pains are modes rather than objects ofperceptions or sensations. In this paper I try to go a stepfurther and argue that there are circumstances when pains canbecome objects even while they remain modes of experience.By analysing cases of extreme pain as presented by Scarry,Sartre, Wiesel, Grahek and Wall, I attempt to show thatintense physical pain may evolve into a force that, likeimagination, can make our most intense state of experiencebecome (...) a mental object. I shall finally argue that, thoughextreme pains cannot serve as paradigm cases, they do showthe general importance of taking pain states to be objects. (shrink)

Euclidean geometry, statics, and classical mechanics, being in some sense the simplest physical theories based on a full-fledged mathematical apparatus, are well suited to a historico-philosophical analysis of the way in which a physical theory differs from a purely mathematical theory. Through a series of examples including Newton’s Principia and later forms of mechanics, we will identify the interpretive substructure that connects the mathematical apparatus of the theory to the world of experience. This substructure includes models of experiments, models of (...) measurement, and modular connections with partial theories. It evolves during the life of a theory as physicists learn how to apply it in various contexts. It should nevertheless be regarded as an integral part of a genuine physical theory since the theory would otherwise degenerate into pure mathematics. (shrink)
