Highlighting the social tensions that confront the liberal tradition, Pierre Manent draws a portrait of what we, citizens of modern liberal democracies, have become. For Manent, a discussion of liberalism encompasses the foundations of modern society, its secularism, its individualism, and its conception of rights. The frequent incapacity of the morally neutral, democratic state to further social causes, he argues, derives from the liberal stance that political life does not serve a higher purpose. Through quick-moving, highly synthetic essays, he (...) explores the development of liberal thinking in terms of a single theme: the decline of theological politics. The author traces the liberal stance to Machiavelli, who, in seeking to divorce everyday life from the pervasive influence of the Catholic church, separated politics from all notions of a cosmological order. What followed, as Manent demonstrates in his analyses of Locke, Hobbes, Rousseau, Guizot, and Constant, was the evolving concept of an individual with no goals outside the confines of the self and a state with no purpose but to prevent individuals from dominating one another. Weighing both the positive and negative effects of such a political arrangement, Manent raises important questions about the fundamental political issues of the day, among them the possibility of individual rights being reconciled with the necessary demands of political organization, and the desirability of a government system neutral about religion but not about public morals.

« La métaphysique d’Aristote n’est, au sens aristotélicien, dialectique et par là incapable de tout achèvement déductif, que parce qu’elle est une métaphysique du mouvement, c’est-à-dire de la scission. » Le propos de l’auteur est simple : sans vouloir rajouter et apporter du nouveau sur Aristote, il tente au contraire de désapprendre tout ce que la tradition a ajouté à l’aristotélisme primitif. Car l’aristotélisme que nous connaissons est surtout celui des commentateurs grecs. L’image ainsi révélée est celle d’un Aristote aporétique, (...) mais « cette voix qui parle est celle plus fraternelle qui continue de chercher en nous ce qu’est l’être et de se taire parfois ».

The aim of this work is to study complex ecological models exhibiting simple dynamics. We consider large scale systems which can be decomposed into weakly coupled subsystems. Perturbation Theory is used in order to get a reduced set of differential equations governing slow time varying global variables. As examples, we study the influence of the individual behaviour of animals in competition and predator-prey models. The animals are assumed to do many activities all day long such as searching for food of (...) different types. The degree of competition as well as the predation pressure are dependent upon these activities. Preys are more vulnerable when doing some activities during which they are very exposed to predators attacks rather than for others during which they are hidden. We study the effect of a change in the average individual behaviour of the animals on interspecific relationships. Computer simulations of the whole sets of equations are compared to simulations of the reduced sets of equations. (shrink)

Gaining momentum during the last third of the twentieth century, the philosophy of biology is now a distinct field with its own debates, journals, audiences, and professional societies. This professionalization came along with the forging of an intellectual identity based on the existence of disciplinary frontiers that demarcated philosophy of biology from neighboring disciplines such as philosophy of medicine, history of biology, or general philosophy of science. Here, I argue that the identity of this emerging philosophy of biology also excluded (...) Continental traditions often called “biological philosophy” or “historical epistemology of the life sciences”. Going back to the 60s and 70s, I explore the emergence of the philosophy of biology at a time when its identity was still in flux and its analytic orientation debated. To do so, I focus primarily on the works of David Hull and Marjorie Grene, and I draw on their unpublished correspondence. Although Grene’s intellectual contribution to the philosophy of biology has been widely acknowledged, her coming from a different philosophical universe created tensions with the identity Hull and others sought to establish. Overall, this chapter raises a question about the historical conditions that make fields such as the philosophy of biology possible, and calls attention to the exclusions that permeated the philosophy of biology from its inception and what this involves in terms of the proper relation between philosophy and science, especially biology.

In this article, I argue that distinguishing ‘evolutionary’ from ‘Darwinian’ medicine will help us assess the variety of roles that evolutionary explanations can play in a number of medical contexts. Because the boundaries of evolutionary and Darwinian medicine overlap to some extent, however, they are best described as distinct ‘research traditions’ rather than as competing paradigms. But while evolu- tionary medicine does not stand out as a new scientific field of its own, Darwinian medicine is united by a number of (...) distinctive theoretical and methodological claims. For example, evolutionary medicine and Darwinian medicine can be distinguished with respect to the styles of evolutionary explanations they employ. While the former primarily involves ‘forward looking’ explanations, the latter depends mostly on ‘backward looking’ explanations. A forward looking explanation tries to predict the effects of ongoing evolutionary processes on human health and disease in contem- porary environments (e.g., hospitals). In contrast, a backward looking explanation typically applies evolutionary principles from the vantage point of humans’ distant biological past in order to assess present states of health and disease. Both approaches, however, are concerned with the prevention and control of human diseases. In con- clusion, I raise some concerns about the claim that ‘nothing in medicine makes sense except in the light of evolution’. (shrink)

Frederick Griffith was an English bacteriologist at the Pathological Laboratory of the Ministry of Health in London who believed that progress in the epidemiology and control of infectious diseases would come only with more precise knowledge of the identity of the causative microorganisms. Over the years, Griffith developed and expanded a serological technique for identifying pathogenic microorganisms, which allowed the tracing of the sources of infectious disease outbreaks: slide agglutination. Yet Griffith is not remembered for his contributions to the biology (...) and epidemiology of infectious diseases so much as for discovering the phenomenon known as ‘transformation’. Griffith’s discovery, for many, was a pure case of serendipity whose biological relevance had also largely escaped him. In this paper, I argue that the key to understanding the significance of bacterial transformation – and the scientific legacy of Fred Griffith – rests not only on it initiating a cascade of events leading to molecular genetics but also on its implications for epidemiology based on the biology of host–parasite interactions. Looking at Griffith’s entire career, instead of focusing only on the transformation study, we can better appreciate the place of the latter within Griffith’s overall contributions. Presented in this way, Griffith’s experiment on bacterial transformation also ceases to appear as an anomaly, which in turn leads us to rethink some of the most prevalent historical conceptions about his work.

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.

In a recently published paper, we argued that theories of cultural evolution can gain explanatory power by being more pluralistic. In his reply to it, Dennett agreed that more pluralism is needed. Our paper’s main point was to urge cultural evolutionists to get their hands dirty by describing the fine details of cultural products and by striving to offer detailed and, when explanatory, varied algorithms or mechanisms to account for them. While Dennett’s latest work on cultural evolution does marvelously well (...) on the first point, it has only whet our appetite on the second. Accordingly, the present paper aims to show what an evolutionary explanation of culture that takes the variety of cultural evolution mechanisms seriously would look like. We will focus on the cultural evolution of social epistemic mechanisms and we will propose that Darwinian algorithms should be complemented with a cultural analogue of the error reduction mechanism proposed to account for human cognition, with a particular emphasis on the necessity to build independencies between different sub-systems in charge of tracking states of the world. To illustrate our point, we will present how the evolution of the legal system as epistemic systems can be understood as a process of building increasingly better independencies and how various criticisms of the actual legal system calls for building even more of them.

In multicellular organisms, cells are frequently programmed to die. This makes good sense: cells that fail to, or are no longer playing important roles are eliminated. From the cell’s perspective, this also makes sense, since somatic cells in multicellular organisms require the cooperation of clonal relatives. In unicellular organisms, however, programmed cell death poses a difficult and unresolved evolutionary problem. The empirical evidence for PCD in diverse microbial taxa has spurred debates about what precisely PCD means in the case of (...) unicellular organisms. In this article, we survey the concepts of PCD in the literature and the selective pressures associated with its evolution. We show that definitions of PCD have been almost entirely mechanistic and fail to separate questions concerning what PCD fundamentally is from questions about the kinds of mechanisms that realize PCD. We conclude that an evolutionary definition is best able to distinguish PCD from closely related phenomena. Specifically, we define “true” PCD as an adaptation for death triggered by abiotic or biotic environmental stresses. True PCD is thus not only an evolutionary product but must also have been a target of selection. Apparent PCD resulting from pleiotropy, genetic drift, or trade-offs is not true PCD. We call this “ersatz PCD.”. (shrink)

In this article, Pierre Hadot examines the late philosophy of Ludwig Wittgenstein and the so-called “linguistic turn” in philosophy and the social sciences. Although certain interpreters of Wittgenstein have thought that Philosophical Investigations shows philosophy to be predicated on a series of confusions based on the misuse of language, Hadot argues contrarily that an understanding of Wittgenstein’s idea of “language games”—far from ending philosophy—allows us to see it anew and to discern the source of some of its deepest perplexities. (...) Of particular concern is the notion of the ancient idea of philosophical discourse as intrinsically connected to various forms of apprenticeship or spiritual formation. It is in this context that the supposed inconsistencies and unusual repetitions of ancient philosophy can be understood. Only from the Middle Ages do philosophical language games begin slowly to become detached from certain kinds of training, of pedagogies connected to forms of life, and become texts—and “systems”—in the sense of being written for the purposes of merely conventional reading.

I present and defend here a thesis named vehicleless externalism for conceptual mental episodes. According to it, the constitutive relations there are between the production of conceptual mental episodes by an individual and the inclusion of this individual in social discursive practices make it non-necessary to equate, even partially, conceptual mental episodes with the occurrence of physical events inside of that individual. Conceptual mental episodes do not have subpersonal vehicles; they have owners: persons in interpretational practices. That thesis is grounded (...) on inferentialism and on the endorsement of the idea that "meaning is normative". After having recapitulated this heritage and after having presented that thesis, the paper especially attempts to articulate how, in that framework, we may then positively conceive the relations there are between conceptual mental episodes, intracranial events and inferential behaviour.

Les émotions ont un rôle important dans nos interactions sociales. Sans émotions, nous avons du mal à faire des choix. Quand notre environnement déçoit nos attentes de manière répétée, nos émotions nous signalent qu'il serait rationnel de changer nos attentes, c'est-à-dire de procéder à des révisions. Le partage des émotions, qui est la clé de notre sentiment d'appartenance à une communauté, nous amène à révéler nos valeurs, parce qu'il permet de résister face à un monde décevant. Si même une fois (...) révisées nos croyances, nos émotions se maintiennent, elles manifestent alors des attentes bien enracinées, qui sont nos valeurs réelles. Pour étudier les valeurs collectives, il faut donc étudier les émotions, la manière dont elles incitent à des révisions, et comment leur partage collectif renforce nos résistances. La rationalité morale s'appuie sur les émotions. Celles-ci sont sensibles aux détails des situations, et cette rationalité dépend des contextes, si bien qu'elle propose des arguments qui restent révisables quand le contexte change. Ne résistent à toute révision que nos sentiments d'injustice. L'originalité de ce livre est donc d'étudier les émotions et les valeurs, individuelles et collectives, dans la dynamique de leurs changements, de leurs révisions et de leurs résistances, et d'utiliser ce lien entre émotions et révisions pour mieux définir la spécificité d'une rationalité morale.

Criticisms and rejections of representationalism are increasingly popular in 4E cognitive science, and especially in radical enactivism. But by overfocusing our attention on the debate between radical enactivism and classical representationalism, we might miss the woods for the trees, in at least two respects: first, by neglecting the relevance of other theoretical alternatives about representationalism in cognitive science; and second by not seeing how much REC and classical representationalism are in agreement concerning basic and problematic issues dealing with mental content (...) and intentionality. In order to expand and exemplify these ideas, this paper presents two heterodox positions on intentionality and on the relations between content and representation. Special attention is paid to the way REC is rejecting these positions: I argue that this rejection reveals common assumptions with classical representationalism, but also undermines the coherence of REC’s conception of intentionality.

Based on an endorsement of the hypothesis of extended cognition , this paper proposes a criticism of the representationalist assumptions that still pertain to these contemporary models of cognition. I first rehearse some basic problems akin to any representationalist model of cognition, before proposing some more specific arguments directed against the necessity, the plausibility, and the coherence of the marriage between extended cognition and contemporary representationalism . Extended and distributed models of cognition have the resources to get rid of representationalism, (...) and they should better do it. Their adherence to representationalism might be an by-product of the extended character of the scientific study of cognition. (shrink)

We present a dynamical model of a multi-site fishery. The fish stock is located on a discrete set of fish habitats where it is catched by the fishing fleet. We assume that fishes remain on fishing habitats while the fishing vessels can move at a fast time scale to visit the different fishing sites. We use the existence of two time scales to reduce the dimension of the model : we build an aggregated model considering the habitat fish densities and (...) the total fishing effort. We explore a regulation procedure, which imposes an average residence time in patches. Several equilibria exist, a Fishery Free Equilibria as well as a Sustainable Fishery Equilibria . We show that the dynamics depends on a threshold which is similar to a basic reproduction ratio for the fishery. When the basic reproduction ratio is less or equal to 1, one of the FFEs is globally asymptotically stable , otherwise one of the SFEs is GAS. (shrink)

La présente étude propose une interprétation de EN, V, 10, en défendant deux thèses: premièrement que la notion centrale de la variabilité du droit naturel signifie la diversité des interprétations que l'on peut donner d'un sentiment communément partagé du juste ou de l'injuste (cf. Rhét., I, 13); deuxièmement que, pour échapper au relativisme de type protagoréen, Aristote défend l'idée d'un régime parfait qui seul peut fournir la meilleure interprétation de ce sentiment.

A presentation and discussion of Gottlob Frege's understanding of language, both natural and artificial, with close attention to his texts.

Editor’s Introduction The following text was prepared by Pierre Bourdieu for delivery at a conference on his work held at Duke University, April 21–23, 1995. Entitled “Pierre Bourdieu: Fieldwork in Culture,” the conference was sponsored by the Duke Graduate Program in Literature and included such well‐known literary scholars as Barbara Herrnstein Smith, Jonathan Culler, and Fredric Jameson. Bourdieu, of course, was the invited guest of honor, but was uncertain as to whether he should make the effort of attending, (...) particularly since he was recovering from a short period of poor health. As I too had been invited , Bourdieu discussed the question with me in Paris.He was rather concerned about wrongheaded, trendy applications of his theories by American literary scholars, who often misunderstand his work because they simply do not know the intellectual landscape to which it relates. Reading such conference paper titles as “Cross‐Dressing for Success: The Scramble for Symbolic Power in Tabitha Sweeney’s Female Quixotism,” Bourdieu confessed his fear of being taken as simply the French intellectual flavor of the month, one whose theory is used simply as grist for the American academy’s industrious mills of literary interpretation.He ultimately decided to send the following text to be read at the conference in his absence. It treats, with polite frankness, his worries about being misinterpreted through importation into the American theoretical field with its peculiar conception of French philosophy; Bourdieu’s paper situates these particular worries within a more general account of “allodoxic”distortions caused by the international travel of theory; but it also tries to prevent further misunderstanding by offering a brief contextualization of his theory and a brief summary of his method of analysis through fields. The translation of Bourdieu’s text was prepared by Loïc Wacquant, and is presented here with only minor adjustments. (shrink)

Il s’agit en somme, dans cet ouvrage, de montrer qu’un vieux problème continue de résister à ceux qui prétendent l’avoir résolu. Ce vieux problème, c’est celui qui est sous-jacent aux paradoxes zénoniens de la Dichotomie et de l’Achille, rassemblés par l’auteur en une même « aporie du passage ». Ceux qui prétendent l’avoir résolu, ce sont principalement des philosophes d’obédience analytique qui s’appuient sur certains développements contemporains des mathématiques infinitaires et sur une cri...

L'assise où se dressaient des statues devant le mur Sud du trésor des Athéniens est couramment appelée « socle marathonien » parce qu'elle porte une dédicace où figure le nom de Marathon. Pour les uns, cette dédicace est celle du trésor lui-même ; pour d'autres, le socle a été accolé à un monument bâti avant 490. La dédicace a été regravée, probablement au IIIe s. av. J.C. ; le texte regravé est en tout point identique à celui de la première (...) inscription, qui a laissé quelques traces, difficiles à dater. On s'est mépris sur la fonction du mot akrothinia dans la dédicace ; le socle ne portait pas un trophée constitué par des pièces du butin, mais des statues. Les fondations du trésor et la terrasse portant le socle ont été bâties en même temps, ce qui confirme que le trésor a été construit après 490. Il ne s'ensuit pas nécessairement que la dédicace du socle soit aussi celle du trésor ; il n'est pas sûr que Pausanias l'ait lue. (shrink)

The academic path of Jean Gayon (1949–2018) follows in the wake of the “French style” in epistemologyEpistemology, but he is also one of the first representatives of philosophy of biology in France. In the light of this double philosophical heritage, this chapter re-examines the relations between the works of Gayon, the tradition in which he first studied, and the one he later adopted, but not without reservations. Tracing his intellectual journey, this article explores why he naturally appears as a Canguilhemian, (...) a view against which he defends himself. Attending to the connexions that he established with the philosophers of biology will bring to light the growing tension that inhabits him, from the middle of the 1980s onwards, and which led him to identify some of the limits inherent to theHistorical epistemology matrix of historical epistemologyGayon, JeanOn historical epistemology, without disowning his first philosophical tradition. Finally, in an attempt to reconcile two approaches, I will underline the emergence in the thought of Jean Gayon of a third way seeking to overcome the opposition between a “unitarian” style that seeks to make a clear break with the history of scienceHistory of science and its philosophical past, and the “dualist” style which tends to stay above scientific debates, and which accepts a clear distinction between the work of science and the work of philosophy. Reuniting the history and the philosophy of the sciences, privileging the long durée and depths of history, where the problems of biology unfold, while also recognizing the value of analysing the conceptual puzzles which structure the contemporary life sciences, the oeuvre of Jean Gayon illustrates the complementary character of these disciplines.

Silvio Berlusconi constitue un phénomène original, et même un cas unique, puisqu'il est le seul chef d'entreprise du secteur des médias qui accède, à deux reprises, aux fonctions de Premier ministre dans une grande démocratie. L'arrivée au pouvoir du dirigeant de la grande entreprise de la communication répond à la crise de la représentation politique et inaugure dans l'Europe latine, une «néo-politique». Comme toute figure symbolique, l'image de Berlusconi est ambivalente et ne peut laisser indifférente. Si Berlusconi suscite tant de (...) réactions d'adhésion ou de rejet, c'est parce qu'il inscrit toute son activité publique dans l'espace de l'image, de la séduction et de l'émotion, plus que dans le champ rationnel et traditionnel de la représentation politique. Il sait être l'ordonnateur du débat public en le dramatisant autour de clivages simplistes, notamment pour ou contre l'État, pour ou contre l'impôt... Il promeut ainsi une politique faite de passions et de croyances, comme dans une fiction télévisuelle. Le phénomène ne relève pas pour autant du populisme, voire du « télépopulisme ».Silvio Berlusconi represents an original phenomenon, or even a unique case, in that he is the only company manager from the world of media who twice rose to the office of Prime Minister in a major democracy. The coming to power of the manager of this large media firm is an answer to the crisis of political representation; it ushers in a "neo-policy" in Latin Europe. Like any symbolical figure, Berlusconi's image is ambivalent and cannot leave indifferent. If Berlusconi gives rise to so many reactions of support or rejection, that is because he places his whole public activity in the field of image, seduction and emotion rather than in the rational and traditional field of political representation. He knows how to organize public debate by dramatizing it around simplistic divides, such as for or against State, for or against taxes... Thus he promotes politics built on passions ans beliefs, as in a television fiction. For all that, the phenomenon does not fall into populism, nor even into "telepopulism". (shrink)
