Researchers from diverse disciplines, including organismal and cellular physiology, sports science, human nutrition, evolution and ecology, have sought to understand the causes and consequences of the surprising variation in metabolic rate found among and within individual animals of the same species. Research in this area has been hampered by differences in approach, terminology and methodology, and the context in which measurements are made. Recent advances provide important opportunities to identify and address the key questions in the field. By bringing together (...) researchers from different areas of biology and biomedicine, we describe and evaluate these developments and the insights they could yield, highlighting the need for more standardisation across disciplines. We conclude with a list of important questions that can now be addressed by developing a common conceptual and methodological toolkit for studies on metabolic variation in animals. (shrink)

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.

A magisterial mappa mundi of the terrain that Pierre Hadot has so productively worked for decades, this ambitious work revises our view of ancient philosophy- ...

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)

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)

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)

An advanced introduction to the new philosophical anthropology and an understanding of the most contemporary developments in it.

In lieu of an abstract, here is a brief excerpt of the content:Montaigne and the Coherence of EclecticismPierre ForceSince the publication of Pierre Hadot's essays on ancient philosophy by Arnold Davidson in 1995,2 Michel Foucault's late work on "the care of the self"3 has appeared in a new light. We now know that Hadot's work was familiar to Foucault as early as the 1950s.4 It is also clear that Foucault's notion of "techniques of the self" is very close to (...) what Hadot calls "spiritual exercises." At the same time, there are important differences between the views of these two philosophers, and Hadot has often expressed his regret that Foucault's untimely death prevented them from exploring these differences.5 One important point of disagreement was the status of eclecticism. In Foucault's interpretation of ancient philosophy, the "constitution of the self" implied a personal choice among disparate philosophical references: "Writing as a personal exercise done by the self and for the self, is an art of disparate truth."6 In a 1989 article Hadot argued from a historical point of view that, so far as Stoicism and Epicureanism were concerned, [End Page 523] eclecticism had no place in a mature practice of philosophy. Foucault's favorite example, Seneca's Letters to Lucilius, in which Stoic arguments were invoked along with Epicurean arguments, was a work for beginners. In a mature practice of Stoicism, one would stick to the arguments of the Stoic school, choose them for their coherence, and instead of trying to forge a spiritual identity for oneself through writing, one would "liberate oneself from one's individuality in order to raise oneself up to universality."7 Hadot added that "it is only in the New Academy—in the person of Cicero, for instance—that a personal choice is made according to what reason considers as most likely at a given moment."8 This discussion of Foucault may give the impression that Hadot was somewhat dismissive of eclecticism. Yet in a 2001 interview Hadot claimed that he had always admired Cicero's intellectual independence, and he proposed a reappraisal "of an attitude that has always had a bad reputation: eclecticism."9Something very similar is a stake in the work of Alexander Nehamas, as Lanier Anderson and Joshua Landy showed in their study of his Art of Living. In the conception of philosophy as a "way of life" (Hadot) or "care of the self" (Foucault) or "self-fashioning" (Nehamas), a central issue is the relationship between theoretical coherence and the coherence of the person who theorizes. Elaborating on Nehamas's chapter on Montaigne, Anderson and Landy argue that there is a move in Montaigne away from doctrinal coherence and towards a coherence of the self. As they put it, "the harmonious whole Montaigne commends [... ] is not a coherent body of fact or theory; it is the unified self of the theorizer."10 Anderson and Landy show that this brings up all kinds of difficulties: can this unified self be other than a fiction? If that is the case, how can philosophy be a way of life? Nehamas's answer is very much in the spirit of the late Foucault: there is a coherence of the self in Montaigne, and this coherence is the product of writing as a philosophical activity. The self is fashioned through writing.Because Montaigne writes in the ancient tradition of philosophy as a way of life, one may recall Hadot's suggestion that Foucault's notion of [End Page 524] "writing the self" is an intriguing but historically inaccurate description of ancient philosophical practice. But perhaps Hadot agrees with Foucault after all, since in his most recent interviews, he speaks favorably of eclecticism, a notion that is central to Foucault's analysis of self-fashioning through writing. The case of Montaigne is particularly interesting for these purposes, not only because the Essays seem to be the prototypical example of "writing the self," but also because eclecticism is both discussed and practiced throughout the Essays. I propose to take a fresh look at this issue by investigating the status of eclecticism in Montaigne's Essays. This must start with an examination of the philosophical tradition most closely associated with... (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.

Στον οπισθόδομο του ναού του Απόλλωνος στους Δελφούς, ένα μνημείο έχει αφήσει τα ίχνη του πάνω στην πλακόστρωση. Η ίδρυση του είναι σύγχρονη με την οικοδόμηση του ναού. Η παρουσία ενός μνημείου στο τμήμα αυτό ενός ναού είναι μοναδικό παράδειγμα * θα πρέπει να εξηγείται από κάποια τοπική ιδιομορφία. Αντιμετωπίζονται δύο υποθέσεις : πρόκειται είτε για ένα άγαλμα του Απόλλωνος αφιερωμένο από τους Αμφικτιονες ως αποζημίωση για την ιεροσυλία των Φωκαέων, είτε για τον ομφαλό. Η δεύτερη υπόθεση θα συμφωνούσε με (...) την πορεία του Παυσανία και, επιπλέον, δεν διαψεύδεται από τους λογαριασμούς οικοδόμησης του ναού. (shrink)

No one is responsible for their conduct because free will is an illusion, say some skeptics. Even when it seems that we have several options, we only have one. Hence, says the free will skeptic, we should reform our practices which involve responsibility attributions, such as punishment and blame. How seriously should we take this doctrine? Is it one that we could live by? One thorn in the side of the skeptic concerns deliberation. When we deliberate about what to do—what (...) film to go see, whom to befriend, which doctrine to follow—we must presume that our options are open to us. But then, every time that skeptics deliberate, they presume something which is incompatible with their doctrine, i.e. that they have several options. In a word, skeptics cannot deliberate qua skeptics. Some philosophers have responded that deliberators don’t have to presume that their options are open; they only have to presume that their choice will be efficacious. I argue that this proposal uses resources which, if they are available and successful, can be employed to refute skepticism. The upshot is that free will skeptics are pushing for a doctrine that is either false or in tension with deliberation. (shrink)

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)

Political judgments usually combine a normative principle or intuition with an appreciation of empirical facts regarding the achievability of different options and their potential consequences. The interesting question dividing partisans of political idealism and realism is whether these kinds of considerations should be integrated into the normative principles themselves or considered apart. At first sight, if a theorist is concerned with guiding political judgments, non-ideal or realist theorizing can seem more attractive. In this article, however, I argue that ideal theorizing (...) might be considered valuable even by theorists moved by a pragmatic concern because it is less exposed to conservatism. I nonetheless contend that the aim to guide action in the world as it is should not be abandoned. Therefore, I outline a four-step method for proceeding from abstract moral principles to concrete political judgments and apply it to a test case. (shrink)

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...

This paper aims to challenge the idea claimed by Putnam in his Dewey Lectures that internal realism presupposed sense data theory so that it would have been unable to account for the fundamental intuition of common sense realism that perception gives us cognitive access to reality. Rather, I argue that Putnam’s writings from the period of internal realism indicate that it (internal realism) already presupposed a form of direct realism of the kind he puts forth in the Dewey lectures. I (...) support my thesis with a demonstration of the implication of direct realism in the refutation of the brain-in-a-vat hypothesis that occurs in the first chapter of Reason, Truth and History, as well as with various passages from the philosopher’s writings of the time when he defended internal realism. I also argue, contrary to what the philosopher seems to assert in his Dewey Lectures, that his model-theoretic argument against metaphysical realism does not involve sense data theory. After noting the very strong resemblance between the theses of his common sense realism of the 1990s and those of his internal realism of the 1980s, I hypothesize that Putnam pretended to renounce internal realism in order to allow himself to rephrase his original position so as to avoid being misinterpreted as a form of idealism or fact constructivism, as was the case with his initial statement.

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)
