We prove that the class of stable models is incomplete with respect to pure λ-calculus. More precisely, we show that no stable model has the same theory as the strongly stable version of Park's model. This incompleteness proof can be adapted to the continuous case, giving an incompleteness proof for this case which is much simpler than the original proof by Honsell and Ronchi della Rocca. Moreover, we isolate a very simple finite set, , of equations and inequations, which has (...) neither a stable nor a continuous model, and which is included in and in , the contextual theory induced by the set of essentially λI-closed terms. Finally, using an approximation theorem suitable for a large class of models , we prove that and are included in , giving an operational meaning to the equality in these models. (shrink)

In this paper, I put forward a benchmark account of emergence in terms of non-explainability and explicate the relationship that exists between its synchronic and diachronic declinations. I develop an argument whose conclusion is that emergence is essentially a “two-faceted” notion, i.e. it always encapsulates both synchronic and diachronic dimensions. I then compare this account with alternative recent accounts of emergence that define the concept through the notion of unpredictability or topological non-equivalence.

This is an introduction to the topical collection Microbes, Networks, Knowledge: Disease Ecology in the twentieth Century, based on a workshop held at Queen Mary, University London on July 6–7 2016. More than twenty years ago, historian of science and medicine Andrew Mendelsohn asked, “Where did the modern, ecological understanding of epidemic disease come from?” Moving beyond Mendelsohn’s answer, this collection of new essays considers the global history of disease ecology in the past century and shows how epidemics and pandemics (...) have made “microbes complex”.

This paper defends a realist account of the composition of Newtonian forces, dubbed ‘residualism’. According to residualism, the resultant force acting on a body is identical to the component forces acting on it that do not prevent each other from bringing about its acceleration. Several reasons to favor residualism over alternative accounts of the composition of forces are advanced. (i) Residualism reconciles realism about component forces with realism about resultant forces while avoiding any threat of causal overdetermination. (ii) Residualism provides (...) a systematic semantics for the term ‘force’ within Newtonian mechanics. (iii) Residualism allows us to precisely apportion the causal responsibility of each component force in the ensuing acceleration. (iv) Residualism handles special cases such as null forces, single forces, and antagonistic forces in a natural way. (v) Residualism provides a neat picture of the causal powers of forces: each force essentially has two causal powers⎯the power to bring about accelerations (sometimes together with other co-directionnal forces) and the power to prevent other forces from doing so⎯exactly one of which is manifested at a time. (vi) Residualism avoids commitment to unobservable effects of forces: forces cause either stresses (tensile or compressive) or accelerations. (shrink)

This paper is concerned with extensions of geometric stability theory to some nonelementary classes. We prove the following theorem:Theorem. Let [Formula: see text] be a large homogeneous model of a stable diagram D. Let p, q ∈ SD(A), where p is quasiminimal and q unbounded. Let [Formula: see text] and [Formula: see text]. Suppose that there exists an integer n < ω such that [Formula: see text] for any independent a1, …, an∈ P and finite subset C ⊆ Q, but (...) [Formula: see text] for some independent a1, …, an, an+1∈ P and some finite subset C ⊆ Q.Then [Formula: see text] interprets a group G which acts on the geometry P′ obtained from P. Furthermore, either [Formula: see text] interprets a non-classical group, or n = 1,2,3 and•If n = 1 then G is abelian and acts regularly on P′.•If n = 2 the action of G on P′ is isomorphic to the affine action of K ⋊ K* on the algebraically closed field K.•If n = 3 the action of G on P′ is isomorphic to the action of PGL2(K) on the projective line ℙ1(K) of the algebraically closed field K.We prove a similar result for excellent classes.

The “species-as-individuals” thesis takes species, or taxa, to be individuals. On grounds of spatiotemporal boundedness, any biological entity at any level of complexity subject to evolutionary processes is an individual. From evolutionary theory flows an ontology that does not countenance universal properties shared by evolving entities. If austere nominalism were applied to evolving entities, however, nature would be reduced to a mere flow of passing events, each one a blob in space–time and hence of passing interest only. Yet if there (...) is genuine biodiversity in nature, if nature is genuinely carved into species, and taxa, then these evolutionary entities will be genuinely differentiated into specific kinds, each species being one of its kind. Given the fact that evolving entities have un-sharp boundaries, an appropriately weak, “non-essentialist” concept of natural kind has to be invoked that does not allow for strong identity conditions. The thesis of this paper is that species are not either individuals, or natural kinds. Instead, species are complex wholes (particulars, individuals) that instantiate a specific natural kind.

Sa célébrité à l'étranger, considérable, masque mal l'obstination française à l'ignorer, à la dénigrer ou à la récuser sans la lire vraiment. Il est vrai que des controverses, des polémiques, des malentendus ont brouillé sa réception. Surprenant, rétif à toute assignation disciplinaire, difficile donc à classer, à l'interstice entre philosophie et sociologie, Baudrillard déroute autant qu'il séduit. Sa liberté de pensée ébranle nos savoirs et nos croyances. L'objet de ce livre est donc moins de constituer une somme d'hommages posthumes que (...) de questionner une oeuvre qui, au-delà des célébrations ponctuelles, connaît un accueil à la fois fasciné et circonspect. Entretiens, études, lettres, essais l'affrontent et s'y confrontent, tantôt avec gratitude et reconnaissance, tantôt avec réticence ou résistance, parfois avec hostilité. Les textes rassemblés émanent d'universitaires, d'intellectuels, d'écrivains qui interrogent sans complaisance une oeuvre essentielle qui n'a eu de cesse d'interpeller le présent. La diversité des auteurs sollicités (Sophie Calle, Michel Deguy, Philippe Dagen, Bernard Edelman, Nathalie Heinich, Michel Maffesoli, Philippe Petit, Anna Sauvagnargues, Bernard Stiegler, Jean-Baptiste Thoret...) était essentielle. Les analyses et les propos tenus par les uns et les autres dialoguent librement avec cette pensée exigeante, féconde, souvent déroutante. Toujours en mouvement, Baudrillard voulait "promouvoir un commerce clandestin des idées, de toutes les idées irrecevables, des idées imprenables". Ce livre répond à cette exigence radicale. (shrink)

In teasing out the diverse origins of our “modern, ecological understanding of epidemic disease” Greater than the parts: holism in biomedicine, 1920–1950, Oxford University Press, Oxford, 1998), historians have downplayed the importance of parasitology in the development of a natural history perspective on disease. The present article reassesses the significance of parasitology for the “invention” of medical ecology in post-war France. Focussing on the works of microbiologist Charles Nicolle and on that of physician and zoologist Hervé Harant, I argue that (...) French “medical ecology” was not professionally insulated from some major trends in parasitology, especially in Tunis where disciplinary borders in the medical sciences collapsed. This argument supports the claim that ecological perspectives of disease developed in colonial context but I show that parasitologists such as Harant built on the works of medical geographers who had called attention to the dynamic and complex biological relations between health and environment in fashioning the field of medical ecology in the mid-1950s. As the network of scientists who contributed to the global emergence of “disease ecology” is widening, both medical geography and parasitology stand out as relevant sites of inquiries for a broader historical understanding of the multiple “ecological visions” in twentieth-century biomedical sciences.

Adolf Reinach belongs to the Brentanian lineage of Austrian Aristotelianism. His theory of social acts is well known, but his account of ownership has been mostly overlooked. This paper introduces and defends Reinach’s account of ownership. Ownership, for Reinach, is not a bundle of property rights. On the contrary, he argues that ownership is a primitive and indivisible relation between a person and a thing that grounds property rights. Most importantly, Reinach asserts that the nature ownership is not determined by (...) positive law but presupposed by it. Some have objected that such realism raises insuperable difficulties as to the origin of ownership, difficulties that could only be dealt with under a more conventionalist approach. I argue that the independence of the nature ownership from positive law is, in fact, compatible with the claim that its existence is dependent on human conventions. (shrink)

In this article, we first describe our general inhibitory-control theory and, then, we describe how we have tested its specific hypotheses on reasoning with brain imaging techniques in adults and children. The innovative part of this perspective lies in its attempt to come up with a brain-based synthesis of Jean Piaget’s theory on logical algorithms and Daniel Kahneman’s theory on intuitive heuristics.

Comment interpréter le regain d'intérêt pour les réflexions sur la transcendance, la quête de sens, la morale et l'éthique dans nos sociétés contemporaines? C'est ce sur quoi Lawrence Olivier et Yves Boisvert se sont penchés dans cet ouvrage ; le premier accuse les théoriciens de la postmodernité d'être de grands fabulateurs qui font la promotion de la reconfiguration des systèmes moraux, tandis que le second reproche aux nihilistes d'être de grands nostalgiques de la Vérité qui ont sombré dans un (...) fatalisme total et un individualisme radical face à l'échec du projet de la modernité. Leur désaccord portant principalement sur l'interprétation à donner à ce retour des grands questionnements sur les valeurs et le sens de la vie, l'hypothèse de base est que les individus ont besoin de croire à une certaine forme de transcendance et qu'ils ressentent un profond besoin de donner un sens à leur vie. Invités à se prononcer sur cette question, anthropologues, philosophes, politicologues, sociologues et théologiens livrent ici leurs propres analyses de cette problématique par un riche panorama des réflexions sur la sexualité, la mort, la mode, l'art, les jeunes de la rue, les activités extrêmes, la religion et la pop psycho. Sans épuiser la problématique de la transcendance contemporaine, cet ouvrage stimulera la curiosité de tous les lecteurs intéressés aux nouvelles valeurs culturelles ou aux nouveaux comportements sociétaux.

La première partie, " Sociologie de Jean-Michel Berthelot ", rassemble les contributions restituant des traits de son œuvre à l'aide d'études de cas précis ou de panoramas plus larges, et balise des domaines de recherche dans lesquels il s'est illustré : sociologie de l'éducation, du corps, des sciences, épistémologie des sciences sociales. La deuxième partie rend compte des perspectives ouvertes par ses travaux et de la manière dont (...) des chercheurs ont mis en œuvre ses réflexions pour leurs propres recherches. Il s'agit donc de restituer la façon dont on peut faire de la sociologie " avec " Jean-Michel Berthelot - à l'aide de ses travaux et des jalons qu'ils posent.

Dirigé par Jean-Christophe Marcel et Olivier Martin, cet ouvrage rassemble les contributions de collaborateurs, d'anciens étudiants ou de proches collègues de Jean-Michel Berthelot. (shrink)

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)

A quick, but inconclusive, way to defend generous realism is to rely on the reciprocal conceptual dependency between component and resultant forces. Conceptually, there cannot be component without compounds, nor compounds, or resultants, without components. If there are only component forces, then they are not really component ; and if there are only resultant forces then there are not really resultant.

Cette monumentale etude d'Olivier Brunet reste assurement la reference majeure concernant la philosophie esthetique de David Hume (1711-1776). Les questions et les problemes relatifs au "beau", au "jugement de gout" ne se presentent pas, dans l'oeuvre du penseur ecossais, de maniere detachee, isolee du reste de sa philosophie. C'est l'un des merites d'Olivier Brunet d'avoir montre que les reflexions de Hume sur l'esthetique sont inseparables de ses concepts essentiels. Ainsi, lorsque l'on recherche les racines conceptuelles de la definition (...) du "jugement de gout" chez Hume, on retrouve les memes jalons qui structurent son ethique. En morale comme en esthetique, les "passions" jouent un role central et sont liees - chacune a leur facon - a l'"utile"; celui-ci participe a la cause du "plaisir esthetique" qui est lui-meme etroitement lie a la fameuse "sympathie", sentiment desinteresse reglant le comportement moral tel que definit par Hume. La boucle est-elle bouclee? Loin de la, car l'esthetique humienne serait encore impossible a saisir, sans y considerer l'usage que le fondateur de l'empirisme moderne fait de ses concepts-phares : la croyance, le scepticisme, l'experience, l'habitude. Olivier Brunet, enfin, ne borne pas son etude a la philosophie esthetique de Hume. De tres belles pages sont consacrees a la relation personnelle que ce dernier entretenait avec l'art, ainsi qu'aux vertus sociales, psychologiques et morales que l'auteur du Traite de la nature humaine deduisait de la contemplation du Beau.

A new study of the 87 coins (29 silver and 58 bronze) of Apollonia in Illyria which comprise the Dimalla treasure. The silver coins have as types a head of Apollo on the right and three nymphs dancing around the hearth of the Nymphaeon on the reverse, with names of mint officers (which are not those of the prytaneis), and having the same weight as the Roman denier. The bronze coins revert to the types that preceded the great 1st c. (...) monetary reform, but with different mint officers, names and above all different weights, which are exactly the same as those of the Roman bronze coins, and probably struck at Corinth by the praefectus of Antonius' fleet, Atratinus. This shows that Apollonia created its own monetary system between 38 and 36 BC, adapting it to the standards of the denier and the new Roman bronze coinage. (shrink)

A French secondary school teacher is committed to the inclusion of adolescents with intellectual disabilities, and aligning her beliefs with her inclusion practices is by no means obvious. She nevertheless succeeds with the support of a school adaptation system at her college, and the results of our field survey, which took the form of a socio-anthropological approach centered on the case study, help to better understand how and why the support she receives from this system allows her to align her (...) beliefs and practices in terms of inclusion. Her beliefs about the education of adolescents with intellectual disabilities are identified, and her practices and the support she receives from the ULIS system are described, and related to her beliefs about inclusion.Our results, which are based on the articulation of three theoretical approaches (multidisciplinary analysis of work situations, clinical activity and constructive ergonomics) allow, in the context of this case study, to better understand the construction of a link between beliefs and practices, but nevertheless questions the support provided by this device for the inclusion ofFrench teachers in the inclusive paradigm.

Although robots can contribute to the understanding of biological behavior, they fail to model the processes by which humans cope with their environment. Both development and learning are characterized by complex relationships that require constant modification. Given present technology, robots can only model behaviors in specific situations and during discrete stages. Robots cannot master the complex relationships that are the hallmark of human behavior.

Faced with the conflict between our intuition that no two things ever share a place at a time and these counterexamples to it, philosophers usually try to find a happy medium between sticking with the original intuition and rejecting all of its counterexamples or giving up the whole intuition and accepting all the counterexamples. Some counterexamples might be rejected on conceptual grounds : one may deny for instance that absolute space is in the same place that the entities located therein (...) on the ground that absolute space is not itself located. One may also reject the distinct existence of some of the entities put forward in the examples : determinable properties might be nothing else than boolean combinations of determinate ones, spots on a screen may be just four dimensional worms whose passing through each other is a matter of part sharing rather than compenetration, etc. But as long as the conceivability of at least one counterexample is granted, the impenetrability intuition has to be weake- ned. To this end, one can weaken either the modal force of the impenetrability intuition or its scope. One may claim for instance that things are impenetrable in our world, but grant that the remaining counterexample refers to genuine metaphysical possibilities (although not natural ones). On the other hand, on may claim that the impenetrability intuition does not bear on every entity in the outside world, but only on some of them. Locke, famously, did not want to give up the metaphysical necessity of impenetrability, but agreed to restrict it to entities of the same kind.4 One other way to restrict the scope of the intuition of impenetrability is to claim that only independent entities (substances, or things proper) are impenetrable , or that only material entities are.

• Thesis to be defended: there are no tropes. • General argument: there are no good way to account for the particularity of tropes (which is essential to tropes). • Six views to be rejected: 1. Tropes particularized by their locations in formal spaces 2. Tropes as scattered particulars 3. Tropes particularized by their bearers 4. Tropes particularised by their constituents 5. Tropes particularized by their individual dependence to their bearers 6. Tropes as primitely particular .

The claim to be defended may be called phenomenological neutral monism: phenomenological neutral monism about perception (or selfless perception): ordinary perception does not intrinsically present us with the distinction between itself and its objects, that is, with the fact that its objects exist (or seem to exist) independently of the perceptual act.

Tout au long des années 80, Derrida a exploré le thème de l’invention et étudié en particulier sa conception cartésienne. Derrida récuse avec force cette dernière pour montrer qu’elle dissimule une conception théologico-politique du sujet, accomplissant sur le plan politique la thèse métaphysique du logocentrisme. Mais, à partir de Psychè. Inventions de l’autre, cette vision est infléchie pour développer la signification positive de ce qu’il finit par appeler « l’invention du même » qui constitue l’un des courants majeurs de l’invention (...) techno-scientifique au sens moderne. Solidaire d’une certaine « politique de la recherche », Descartes voit l’une de ses inventions, la « langue universelle », être pour la première fois « contresignée » par Derrida. Cette reconnaissance ne doit pas toutefois cacher un désaccord où se révèle l’originalité de la pensée derridienne de l’invention : résolument anticartésienne, elle propose une inventio qui, en tant qu’elle confond avec le jeu même de la « différance », s’exclut de la cogitatio. Événement immanent à la res extensa qui, pour cette raison, ne saurait être entièrement rationalisé et qui, c’est significatif, en même temps qu’il s’ouvre à la chance, renvoie à une autre conception de l’être-ensemble. L’invention porte dans son excès, selon Derrida, l’annonce d’un temps nouveau. (shrink)

Tel qu’Arrien l’indique dans les Entretiens, le cours d’Épictète comprenait une partie technique, où l’apprentissage de la doctrine et des démonstrations était de mise, et une autre, à laquelle nous avons seulement accès, où le maître discutait plus librement avec des interlocuteurs de tous horizons sur des sujets d’ordre spécifiquement éthiques en interprétant la doctrine stoïcienne selon ses propres catégories conceptuelles. Cette deuxième séquence pédagogique interroge directement l’utilité de la première, et engage une réflexion plus large sur l’école philosophique, reprenant (...) la discussion traditionnellement menée entre stoïciens et académiciens sur la scholè. Épictète apporte ainsi un éclairage original sur le rôle, le sens et la fonction des pratiques scolaires à l’époque romaine, dans la perspective stoïcienne d’une vie philosophiquement authentique, en accord avec la nature.

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.

The identification of neural substrates underlying the long lasting debilitating impact of drug cues is critical for developing novel therapeutic tools. Metabolic coupling has long been considered a key mechanism through which astrocytes and neurons actively interact in response of neuronal activity, but recent findings suggested that disrupting metabolic coupling may represent an innovative approach to prevent memory formation, in particular drug‐related memories. Here, we review converging evidence illustrating how memory and addiction share neural circuitry and molecular mechanisms implicating lactate‐mediated (...) metabolic coupling between astrocytes and neurons. With several aspects of addiction depending on mnemonic processes elicited by drug experience, disrupting lactate transport involved in the formation of a pathological learning, linking the incentive, and motivational effects of drugs with drug‐conditioned stimuli represent a promising approach to encourage abstinence.

This article analyses the conditions of formation of the concept of “race” in natural history in the middle of the eighteenth century. Relying on the method of historical epistemology to avoid some of the aporias raised by the traditional historiography of “racism”, it focuses on the peculiarities of the concept of “race” in contrast to other similar concepts such as “variety”, “species” and tries to answer the following questions: to what extent the concept of “race” was integrated in natural history’s (...) discourses before the middle of the eighteenth century? To which kind of concepts and problems was it linked and to which style of reasoning did it pertain? To which conditions could it enter natural history and develop in it? The article argues that “race” pertained to a genealogical style of reasoning which was largely extraneous to natural history before the middle of the eighteenth century. Natural history was rather dominated by a different style of reasoning, a logical and classificatory style, whose principles and concepts were strong obstacles to the development of a concept of “race”. To understand how the concept of “race” developed in natural history, one should understand how the genealogical style of reasoning entered natural history and modified the very principles of classification that organized it. I try to establish that it is through Buffon and some of the main authors of the “monogenist” tradition that the most fundamental conditions for the integration of a genealogical style of reasoning and the development of a concept of “race” are met. To put it clearly, in contrast to many scholars’ analysis – and following some intuitions of P.R Sloan – I argue that Buffon in particular, and monogenism in general, were decisive in the integration and development of the concept of “race” in natural history.

Many recent studies on network technologies and cities share an alarmist view of the impact of technological or regulatory change in utility sectors on the social and spatial fabric of cities, pointing to growing discrimination and inequalities, alienation, enhanced social exclusion and urban “splintering” on a universal scale. A science and technology study perspective on these matters is helpful in moving beyond this “universal alarmism” by emphasizing the ambivalence inherent to all technologies, the significant potential of contestation of, and resistance, (...) to technology-supported forms of discrimination, and the deeply contingent nature of the process of appropriation of new technologies and, as a consequence, of the social “effects” of technologies. Adopting this perspective would mean actively searching for and exploring these context-dependent and often conflictive appropriation processes. For it is in these spaces that we might begin to identify urban technological politics that break free from an intellectually and politically disabling technological pessimism. (shrink)

Les nombreux débats conflictuels entourant l’application du principe de grève de masse au sein du Parti social-démocrate allemand témoignent de la lente agonie des idéaux marxistes au sein de ce parti de masse. La fragile victoire des idéaux prônés par la faction radicale du Parti contre ceux des réformistes, entre 1900 et 1906, connaît un retour de balancier sans appel après la première révolution russe. De 1906 à 1910, la logique légalo-parlementaire allait progressivement devenir la seule voie légitime aux yeux (...) des dirigeants du Parti. Ce changement de tactique et de stratégie visant à conquérir le pouvoir, sera grandement contesté par plusieurs militants influents du Parti. Le conflit intellectuel entre Rosa Luxemburg et Karl Kautsky, qui éclata publiquement en 1910 alors que les mouvements contestataires en Allemagne étaient très forts, nous permet de comprendre, par l’analyse du discours de ces penseurs marxistes, les raisons qui conduisirent le SPD à ne pas appliquer la grève de masse. Ceci, alors qu’une motion favorable à ce principe avait été votée en 1905 lors du Congrès d’Iéna. Du point de vue pseudo-sérendipien qui était le sien, Luxemburg croyait fermement que la temporalité était favorable à l’application de la grève de masse. L’interprétation temporelle et électoraliste de Kautsky l’amènera plutôt à critiquer les effets pseudo-sérendipiens, non contrôlés par le SPD, entourant ce type d’action politique. (shrink)
