Developmental dyscalculia (DD) is a pervasive difficulty affecting number processing and arithmetic. It is encountered in around 6% of school-aged children. While previous studies have mainly focused on general cognitive functions, the present paper aims to further investigate the hypothesis of a specific numerical deficit in dyscalculia. The performance of 10- and 11-year-old children with DD characterised by a weakness in arithmetic facts retrieval and age-matched control children was compared on various number comparison tasks. Participants were asked to compare a (...) quantity presented in either a symbolic (Arabic numerals, number words, canonical dots patterns) or a nonsymbolic format (noncanonical dots patterns, and random sticks patterns) to the reference quantity 5. DD children showed a greater numerical distance effect than control children, irrespective of the number format. This favours a deficit in the specialised cognitive system underlying the processing of number magnitude in children with DD. Results are discussed in terms of access and representation deficit hypotheses. (shrink)

For the last three decades, physicists have been moving beyond the boundaries of their discipline, using their methods to study various problems usually instigated by economists. This trend labeled ‘econophysics’ can be seen as a hybrid area of knowledge that exists between economics and physics. Econophysics did not spring from nowhere—the existing literature agrees that econophysics emerged in the 1990s and historical studies on the field mainly deal with what happened during that decade. This article aims at investigating what happened (...) before the 1990s by clarifying the epistemic background that might have paved the way to the emergence of econophysics. This historical exploration led me to highlight the active role played by the Santa Fe Institute by promoting interdisciplinary research on complexity in 1980s. Precisely, by defining three research themes on economic complexity, the SFI defined a research agenda and a way of extending physics\biology to economics. This article offers a possible archeology of econophysics to clarify what could have contributed to the development of a particular episteme in the 1980s easing the advent of econophysics in the 1990s.

The explosion of health-related costs in U.S. firms over more than a decade is a huge concern for managers. The initiation of Health and Safety programs at the firm level is an adequate Corporate Social Responsibility initiative to contain this evolution. However, in spite of their documented efficiency, firms underinvest in those programs. This appears as a puzzle for health economists. In this paper, we uncover a strong negative relation of financial leverage to the implementation of H&S programs. The negative (...) impact of debt on investment and CSR activities is generally interpreted as an efficient disciplinary effect of debt on managers. H&S are particularly well suited to revisit this evidence, given their strong profitability and homogeneity across firms. Very interestingly, the negative effect is stronger for firms with high free cash flows, for which debt is used to prevent overinvestment. This strongly suggests that debt, while disciplining managers, also discourages investments which are valuable both for firms and society. (shrink)

What is philosophy of science? Numerous manuals, anthologies or essays provide carefully reconstructed vantage points on the discipline that have been gained through expert and piecemeal historical analyses. In this paper, we address the question from a complementary perspective: we target the content of one major journal of the field—Philosophy of Science—and apply unsupervised text-mining methods to its complete corpus, from its start in 1934 until 2015. By running topic-modeling algorithms over the full-text corpus, we identified 126 key research topics (...) that span across 82 years. We also tracked their evolution and fluctuating significance over time in the journal articles. Our results concur with and document known and lesser-known episodes of the philosophy of science, including the rise and fall of logic and language-related topics, the relative stability of a metaphysical and ontological questioning (space and time, causation, natural kinds, realism), the significance of epistemological issues about the nature of scientific knowledge as well as the rise of a recent philosophy of biology and other trends. These analyses exemplify how computational text-mining methods can be used to provide an empirical large-scale and data-driven perspective on the history of philosophy of science that is complementary to other current historical approaches.

With a meta-analysis of 85 studies and 190 experiments, the authors test the relationship between socially responsible investing and financial performance to determine whether including corporate social responsibility and ethical concerns in portfolio management is more profitable than conventional investment policies. The study also analyses the influence of researcher methodologies with respect to several dimensions of SRI on the effects identified. The results indicate that the consideration of corporate social responsibility in stock market portfolios is neither a weakness nor a (...) strength compared with conventional investments; the heterogeneous results in prior studies largely reflect the SRI dimensions under study.

Human expression is open-ended, versatile, and diverse, ranging from ordinary language use to painting, from exaggerated displays of affection to micro-movements that aid coordination. Here we present and defend the claim that this expressive diversity is united by an interrelated suite of cognitive capacities, the evolved functions of which are the expression and recognition of informative intentions. We describe how evolutionary dynamics normally leash communication to narrow domains of statistical mutual benefit, and how expression is unleashed in humans. The relevant (...) cognitive capacities are cognitive adaptations to living in a partner choice social ecology; and they are, correspondingly, part of the ordinarily developing human cognitive phenotype, emerging early and reliably in ontogeny. In other words, we identify distinctive features of our species' social ecology to explain how and why humans, and only humans, evolved the cognitive capacities that, in turn, lead to massive diversity and open-endedness in means and modes of expression. Language use is but one of these modes of expression, albeit one of manifestly high importance. We make cross-species comparisons, describe how the relevant cognitive capacities can evolve in a gradual manner, and survey how unleashed expression facilitates not only language use, but also novel behaviour in many other domains too, focusing on the examples of joint action, teaching, punishment, and art, all of which are ubiquitous in human societies but relatively rare in other species. Much of this diversity derives from graded aspects of human expression, which can be used to satisfy informative intentions in creative and new ways. We aim to help reorient cognitive pragmatics, as a phenomenon that is not a supplement to linguistic communication and on the periphery of language science, but rather the foundation of the many of the most distinctive features of human behaviour, society, and culture.

From John Maynard Keynes’s prediction of a fifteen-hour workweek to present-day speculation about automation, we have not stopped forecasting the end of work. Critical theory and political philosophy have turned their attention away from the workplace to focus on other realms of domination and emancipation. But far from coming to an end, work continues to occupy a central place in our lives. This is not only because of the amount of time people spend on the job. Many of our deepest (...) hopes and fears are bound up in our labor—what jobs we perform, how we relate to others, how we might flourish. The Return of Work in Critical Theory presents a bold new account of the human significance of work and the human costs of contemporary forms of work organization. A collaboration among experts in philosophy, social theory, and clinical psychology, it brings together empirical research with incisive analysis of the political stakes of contemporary work. The Return of Work in Critical Theory begins by looking in detail at the ways in which work today fails to meet our expectations. It then sketches a phenomenological description of work and examines the normative premises that underlie the experience of work. Finally, it puts forward a novel conception of work that can renew critical theory’s engagement with work and point toward possibilities for transformation. Inspired by Max Horkheimer’s vision of critical theory as empirically informed reflection on the sources of social suffering with emancipatory intent, The Return of Work in Critical Theory is a lucid diagnosis of the malaise and pathologies of contemporary work that proposes powerful remedies.

The concept of “life” certainly is of some use to distinguish birds and beavers from water and stones. This pragmatic usefulness has led to its construal as a categorical predicate that can sift out living entities from non-living ones depending on their possessing specific properties—reproduction, metabolism, evolvability etc. In this paper, we argue against this binary construal of life. Using text-mining methods across over 30,000 scientific articles, we defend instead a degrees-of-life view and show how these methods can contribute to (...) experimental philosophy of science and concept explication. We apply topic-modeling algorithms to identify which specific properties are attributed to a target set of entities (bacteria, archaea, viruses, prions, plasmids, phages and the molecule of adenine). Eight major clusters of properties were identified together with their relative relevance for each target entity (two that relate to metabolism and catalysis, one to genetics, one to evolvability, one to structure, and—rather unexpectedly—three that concern interactions with the environment broadly construed). While aligning with intuitions—for instance about viruses being less alive than bacteria—these quantitative results also reveal differential degrees of performance that have so far remained elusive or overlooked. Taken together, these analyses provide a conceptual “lifeness space” that makes it possible to move away from a categorical construal of life by empirically assessing the relative lifeness of more-or-less alive entities.

This article offers a contribution to the history of scientific ideas by proposing an epistemological argument supporting the assumption made by Miller whereby Niels Bohr has been influenced by cubism when he developed his non-intuitive complementarity principle. More specifically, this essay will identify the Bergsonian durée as the conceptual bridge between Metzinger and Bohr. Beyond this conceptual link between the painter and the physicist, this paper aims to emphasize the key role played by art in the development of human knowledge.

■ Evidence from functional neuroimaging studies on resting state suggests that there are two distinct anticorrelated cortical systems that mediate conscious awareness: an “extrinsic” system that encompasses lateral fronto-parietal areas and has been linked with processes of external input (external awareness), and an “intrinsic” system which encompasses mainly medial brain areas and..

Cet essai se propose de retracer le parcours de John Milton, formidable poète, mais aussi prosateur au service de la cause républicaine dans l’Angleterre révolutionnaire des années 1640-1660. On y découvre un penseur radical contrarié, figure puritaine s’il en faut, mais également un écrivain doué d’un humanisme profond. Ces tensions créatrices l’amènent à réconcilier, d’une manière peu banale, l’homme avec Dieu pour poser la liberté, qu’elle soit personnelle, domestique ou politique. This essay purports to show the life and works of (...) John Milton, universally known as a brilliant poet, but we should also remember him as an unequalled pamphleteer defending the republican cause in revolutionary England 1640-1660. There we discover a thwarted radical thinker, caught between humanism and Puritanism. Yet Milton eventually manages to reconcile God’s sovereignty with man’s liberty in quite an original way as he asserts freedom in all fields. (shrink)

Cultural Attraction Theory (CAT), also referred to as cultural epidemiology, is an evolutionary theory of culture. It provides conceptual tools and a theoretical framework for explaining why and how ideas, practices, artifacts and other cultural items spread and persist in a community and its habitat. It states that cultural phenomena result from psychological or ecological factors of attraction.

We hypothesize that when honesty is not motivated by selfish goals, it reveals social preferences that have evolved for convincing strategically vigilant partners that one is a person worth cooperating with. In particular, we explain how the patterns of dishonest behavior observed in recent experiments can be motivated by preferences for social and self-esteem. These preferences have evolved because they are adaptive in an environment where it is advantageous to be selected as a partner by others and where these others (...) are strategically vigilant: they efficiently evaluate the expected benefit of cooperating with specific partners and attend to their intentions. We specify the adaptive value of strategic vigilance and preferences for social and self-esteem. We argue that evolved preferences for social and self-esteem are satisfied by applying mechanisms of strategic vigilance to one's own behavior. We further argue that such cognitive processes obviate the need for the evolution of preferences for fairness and social norm compliance. (shrink)

We also investigated the evolution of these topics over time and their fluctuating significance in the journal articles. Our results concur with known episodes or traits of the discipline—for instance, the significance of evolution-related topics or the decrease of articles with a marked historical dimension—but also highlight a diversity of topics that is much richer than what is usually acknowledged.

Un nouveau type de paternalisme s’est développé ces dix dernières années sous l’impulsion de travaux innovateurs de certains économistes comportementaux. Ce nouveau type de paternalisme, que j’appelle ici paternalisme comportemental, s’est popularisé grâce à la théorie du « coup de pouce » de Richard Thaler et Cass Sunstein et remet en question l’idée selon laquelle le paternalisme serait inacceptable dans nos sociétés. L’objet de cet article est d’évaluer sa légitimité morale sans, néanmoins, se limiter à son supposé libertarianisme. Les résultats (...) de mon investigation peuvent se résumer ainsi : bien que le paternalisme comportemental soit généralement reconnu pour son caractère libéral, il ne satisfait pas en fait les conditions de ce que Joel Feinberg nomme le « paternalisme mou ». Néanmoins, il possède des qualités morales sous-estimées par ses partisans. Il résiste d’abord très bien à la critique égalitariste d’Elizabeth Anderson. A la différence des formes traditionnelles de paternalisme, le paternalisme comportemental n’est pas dégradant et n’est pas ostracisant. Le paternalisme comportemental, enfin, peut se targuer d’être véritablement altruiste, à la condition, cependant, d’abandonner les hypothèses principales de Sunstein et Thaler.

Crise de la gouvernance politique? Certainement. Démarquage, différences et divergences face au capitalisme mondial et existentiel? Oui encore. (shrink)

Cette étude examine la philosophie naturelle de Nicolas Malebranche et son devenir au cours du XVIIIe siècle. Des savants énoncent ou discutent des principes, des lois et des méthodes explicatives dont l'origine est à chercher dans De la recherche de la vérité. La présence de Malebranche se manifeste alors par un occasionnalisme physique et par une critique de la force des corps au repos de Descartes, ce qui conduit à une conception nomologique de la causalité et à un rejet de (...) la force d'inertie, et par une interprétation des phénomènes physico-chimiques à l'aide de la théorie des petits tourbillons. Malebranche est ainsi à l'origine d'une des formes prises par la philosophie mécanique dont ce livre établit les caractéristiques essentielles."--Page 4 of cover. (shrink)

This paper explores the notion of 'relational values' from a phenomenological point of view. In the first place, it stresses that in order to make full sense of relational values, we need to approach them through a relational ontology that surpasses dualistic descriptions of the world structured around the subject and the object. With this aim, the paper turns to ecophenomenology's attempt to apprehend values from a first-person perspective embedded in the lifeworld, where our entanglement with other beings is not (...) a theoretical construction but a palpable reality. Overall, the article's main purpose is to show that, in our direct and raw experience, values do not appear as subjective judgments or as objective properties but as events in which we participate alongside other human and non-human beings.

As a discipline of its own, the philosophy of science can be traced back to the founding of its academic journals, some of which go back to the first half of the twentieth century. While the discipline has been the object of many historical studies, notably focusing on specific schools or major figures of the field, little work has focused on the journals themselves. Here, we investigate contemporary philosophy of science by means of computational text-mining approaches: we apply topic-modeling algorithms (...) to eight major philosophy of science journals, from the 1930s up until 2017. Based on the full-text content of some 15,897 articles, we identified 25 research themes and 8 thematic clusters that show how the research agenda of the philosophy of science has changed in its content over the course of the last eight decades, up to the philosophy of science we now know. We also show how each one of the journals contributed in its own way to this thematic evolution. (shrink)

S’il est bien une passion libre pour Descartes, c’est la générosité. Or, si toutes le sont pour Sartre, la générosité n’en est pas moins la passion de la liberté. On ne s’étonnera donc pas que Sartre puisse, avec Descartes, faire l’éloge de la générosité. On le fera néanmoins à le voir aussi bien, contre lui, en faire la critique. Sans doute cette ambivalence dans le traitement de la générosité par Sartre s’explique-t‑elle par l’ambiguïté de cette passion elle-même. Mais son auteur (...) n’est pas sans jouer double jeu, feignant d’être stupide dans la présentation qu’il donne de la position de Descartes relativement au problème des passions, pour que sa propre conception de celles-ci et de la liberté qui y préside paraisse d’autant plus subtile.

I analyse the impact of search engines on our cognitive and epistemic practices. For that purpose, I describe the processes of assessment of documents on the Web as relying on distributed cognition. Search engines together with Web users, are distributed assessment systems whose task is to enable efficient allocation of cognitive resources of those who use search engines. Specifying the cognitive function of search engines within these distributed assessment systems allows interpreting anew the changes that have been caused by search (...) engine technologies. I describe search engines as implementing reputation systems and point out the similarities with other reputation systems. I thus call attention to the continuity in the distributed cognitive processes that determine the allocation of cognitive resources for information gathering from others. (shrink)

Showing a very early interest in Descartes, after having first considered him as a Christian thinker in the perspective of a deconstruction of religious life, Heidegger soon regards him as the major obstacle to the phenomenological analyses he wants to develop, as part of the first ontological search he gave himself: that of a hermeneutics of facticity. Therefore, the latter immediately takes in his work the shape of a hermeneutics of the I think, therefore I am, its author being blamed (...) for having entirely ignored the sense of being in the I am, focused as he is on the thinking ego, the ins and outs of which he develops. But the criticism also applying to Husserl, it is by laying the blame on his master, that Heidegger intends to radicalize the project of his own master, hence the necessity to throw light on the origin and the foundations of what we can call the Cartesian question in Heidegger.

All known chimpanzee populations have been observed to hunt small mammals for meat. Detailed observations have shown, however, that hunting strategies differ considerably between populations, with some merely collecting prey that happens to pass by while others hunt in coordinated groups to chase fast-moving prey. Of all known populations, Taï chimpanzees exhibit the highest level of cooperation when hunting. Some of the group hunting roles require elaborate coordination with other hunters as well as precise anticipation of the movements of the (...) prey. The meat-sharing rules observed in this community guarantee the largest share of the meat to hunters who perform the most important roles leading to a capture. The learning time of such hunting roles is sometimes especially long. Taï chimpanzee males begin hunting monkeys at about age 10. The hunters’ progress in learning the more sophisticated hunting roles is clearly correlated with age; only after 20 years of practice are they able to perform them reliably. This lengthy learning period has also been shown in some hunter-gatherer societies and confirms the special challenge that hunting represents. (shrink)

Many researchers consider cancer to have molecular causes, namely mutated genes that result in abnormal cell proliferation (e.g. Weinberg 1998). For others, the causes of cancer are to be found not at the molecular level but at the tissue level where carcinogenesis consists of disrupted tissue organization with downward causation effects on cells and cellular components (e.g. Sonnenschein and Soto 2008). In this contribution, I ponder how to make sense of such downward causation claims. Adopting a manipulationist account of causation (...)

However, I also argue that such downward causation claims might point at particularly interesting dynamic properties of causal relationships that might prove salient in characterizing causal relationships (following Woodward 2010).

La fin du xixe siècle est une période difficile pour les Français. La défaite de 1871, la chute du régime impérial, les déboires de la Troisième République et le krach de 1882 les ont amenés à douter de la capacité de leurs gouvernants. La société se fragilise et se divise, favorisant la montée du boulangisme et de l’antisémitisme. Charles Maurras et l’Action française en profitent également, après le suicide du général Boulanger en 1891 et la condamnation du capitaine Dreyfus en (...) 1894. Comtien convaincu, Maurras prend régulièrement position contre Rousseau, dans lequel il voit le principal responsable de la décadence morale et politique de la France.

Cette étude a pour objet la mention – très inhabituelle – d’images de « souris » parmi le tribut des Philistins accompagnant le retour de l’arche dans le récit de 1 Samuel 5-6. Sur la base d’une comparaison entre les principaux témoins anciens du texte de Samuel, on argumente ici que cette mention reflète une série d’interprétations successives, à l’intérieur desquelles on peut distinguer (au moins) trois étapes. À l’origine, la mention de souris semble relever d’une glose scribale, ayant pour (...) fonction de donner forme aux images de « tumeurs » apportées par les Philistins en tribut selon 1 Samuel 6. Plus tard, les images de souris ont été comprises comme formant un tribut distinct, ce qui a donné ensuite naissance à la tradition d’un fléau de souris dans le territoire philistin, tel qu’on le trouve raconté dans les principaux témoins grecs de 1 Samuel 5. Au terme de ce processus, les souris sont devenues un agent du dieu d’Israël, ce qui rapproche ce dernier de l’Apollon Smintheus. Les « souris » de 1 S 5-6 forment ainsi un objet textuel complexe, dont l’analyse demande de combiner une perspective philologique avec des considérations relevant plus franchement de l’histoire des religions.

Science is now studying biodiversity on a massive scale. These studies are occurring not just at the scale of larger plants and animals, but also at the scale of minute entities such as bacteria and viruses. This expansion has led to the development of a specific sub-field of “microbial diversity”. In this paper, I investigate how microbial diversity faces two of the classical issues encountered by the concept of “ biodiversity ”: the issues of defining the units of biodiversity and (...) of choosing a mathematical measure of diversity. I also show that the extension of the scope of biodiversity to microbial entities such as viruses and many other not-clearly-alive entities raises yet another foundational issue: that of defining a “lower-limit” of biodiversity.

Ignoring most published evidence on wild chimpanzees, Tomasello et al.'s claim that shared goals and intentions are uniquely human amounts to a faith statement. A brief survey of chimpanzee hunting tactics shows that group hunts are compatible with a shared goals and intentions hypothesis. The disdain of observational data in experimental psychology leads some to ignore the reality of animal cognitive achievements.

La vie est-elle un phénomène émergent ?

Le présent article examine la façon dont John Dewey a entrepris de poser le problème de la valuation et de ses conséquences au sein de sa théorie de l’éducation. Plus spécifiquement, nous voudrions montrer que son effort pour repenser l’articulation des moyens et des fins du processus de valuation contribue à repenser l’enquête morale. Celle-ci, si elle fait alors l’objet d’une pédagogie qui met au centre l’expérience vécue du sujet, nous oblige à concevoir à nouveaux frais les valeurs que nous (...) accordons aux connaissances apprises. Notre analyse entend démontrer que : 1) de même que dans le domaine éthique, rien n’a de valeur en soi pour le sujet agissant. Mais que 2) la valuation de tout acte est déterminée en situation, alors, 3) dans le domaine de la pédagogie, aucune connaissance n’a de valeur en soi pour l’élève. 4) Ainsi la première tâche de l’enseignant.e est de former l’élève à des processus de valuation efficaces. Cela dans le but que celui-ci puisse à son tour, clairement, déterminer pour lui-même les connaissances qui auront de la valeur. Si notre hypothèse est juste alors cette tâche devient à la fois un point de départ important de la pédagogie pragmatiste et un impératif incontournable de l’éthique enseignante. -/- The present article examines how Dewey addressed the problem of value, as well as the consequences that this solution had for his educational theory. More specifically, I aim to show that Dewey’s effort to rethink means and ends within the process of valuation contributes to a recasting of moral inquiry. If moral inquiry becomes part of a pedagogy that focuses upon the lived experience of the subject, this compels us to rethink the value we attribute to acquired knowledge. My analysis will demonstrate 1) that even within the ethical domain, nothing has value in itself for the acting subject, but that 2) the value of all acts must be determined within specific situations, and therefore 3) within the domain of pedagogy, no knowledge has value in and of itself for the student. 4) Thus the first task of the teacher is to teach students how to evaluate questions of value, which will push them to determine for themselves what knowledge has value. If my hypothesis is correct, this task becomes simultaneously an important starting place for pragmatist pedagogy and a cornerstone of a new ethic of teaching. (shrink)

Le present livre propose l'etude de la constitution, durant le haut Moyen Age latin, d'une position philosophique: le realisme de l'immanence a propos des universaux. Cette position est fondee sur la conviction qu'il existe, dans le monde qui nous entoure, certes des individus particuliers - ce tilleul, cette tortue -, mais aussi des entites universelles. Ces entites n'existent pas separees des individus, mais integralement realisees en eux, sans variation ni degre. Cet engagement philosophique resulte d'une exegese des Categories d'Aristote, reinterpretees (...) selon des philosophemes issus de la pensee de Porphyre. La genealogie de cette position est ici retracee en abordant successivement ses sources tant grecques que latines et ses ancetres patristiques (avant tout Gregoire de Nysse), puis son elaboration conceptuelle durant les premiers siecles du Moyen Age latin jusqu'a la critique qu'en donnera Pierre Abelard, et ce, par l'analyse de l'ontologie des quatre philosophes qui l'ont soutenue: Jean Scot Erigene, Anselme de Canterbury, Odon de Cambrai et Guillaume de Champeaux. Ce parcours permet de dessiner les contours d'un projet philosophique: comprendre, analyser et decrire le monde sensible au moyen des concepts issus de la logique aristotelicienne. (shrink)

Luminance and color are strong and self-sufficient cues to pictorial depth in visual scenes and images. The present study investigates the conditions Under which luminance or color either strengthens or overrides geometric depth cues. We investigated how luminance contrasts associated with color contrast interact with relative height in the visual field, partial occlusion, and interposition in determining the probability that a given figure is perceived as ‘‘nearer’’ than another. Latencies of ‘‘near’’ responses were analyzed to test for effects of attentional (...) selection. Figures in a pair were supported by luminance contrast or isoluminant color contrast and combined with one of the three geometric cues. The results of Experiment 1 show that luminance contrasts associated with hue, when it does not interact with other hues, produces the same effects as achromatic luminance contrasts: The probability of‘‘near’’ increases with luminance contrast while the latencies for ‘‘near’’ responses decrease. Partial occlusion is found to be a strong enough pictorial cue to support a weaker red luminance contrast. Interposition cues lose out against cues of spatial position and partial occlusion. The results of Experiment 2, with isoluminant displays of varying color contrast, reveal that red color contrast on a light background supported by any of the three geometric cues wins over green or white supported by any of the three geometric cues. On a dark background, red color contrast supported by the interposition cue loses out against green or white color contrast supported by partial occlusion. These findings reveal that color is not an independent depth cue, but is strongly influenced by luminance contrast and stimulus geometry. Systematically shorter response latencies for stronger ‘‘near’’ percepts demonstrate that selective visual attention reliably detects the most likely depth cue combination in a given configuration.

Do trees of life have roots? What do these roots look like? In this contribution, I argue that research on the origins of life might offer glimpses on the topology of these very roots. More specifically, I argue (1) that the roots of the tree of life go well below the level of the commonly mentioned ‘ancestral organisms’ down into the level of much simpler, minimally living entities that might be referred to as ‘protoliving systems’, and (2) that further below, (...) a system of roots gradually dissolves into non-living matter along several functional dimensions. In between non-living and living matter, one finds physico-chemical systems that I propose to characterize by a ‘lifeness signature’. In turn, this ‘lifeness signature’ might also account for a diverse range of biochemical entities that are found to be ‘less-than-living’ yet ‘more-than-non-living’. (shrink)

Dans cet article, j’entends décrire comment évolue la philosophie de la physique de Weyl au cours de la période 1918-1927. Je rappellerai en particulier qu’il développe différentes formes d’« apriorisme» entre 1918 et 1923: un apriorisme « spéculatif» avec sa théorie unifiée des champs, puis une conception des connaissances a priori largement inspirée de la Wesensanalyse de Husserl dans ses travaux sur le problème de l’espace. Je montrerai par ailleurs que le holisme de Weyl, i.e., la thèse selon laquelle seule (...) une théorie physique envisagée comme un tout peut faire l’objet de tests empiriques, occupe le devant de la scène dès 1924-1925 dans des textes qui portent sur les fondements des mathématiques. Ce holisme est étroitement lié à sa conception de la théorie physique comme construction symbolique de la réalité. Au bout du compte je caractériserai le point de vue holiste de Weyl en le comparant à certaines réflexions développées par Cassirer, Einstein et Hilbert à peu près au même moment. (shrink)

This essay is intended to explore relations between work and subjectivity (that is, what concerns the individual subject: his or her suffering, pleasure, personal development, and so on). To this end, we shall draw on a body of theory and clinical practice that has been developing in France for some twenty years under the name of the `psychodynamics of work' and ask the three following questions. What is work? This question might seem trivial, but the clinical analysis of the relationship (...) between work and subjectivity shows that work is inseparable from suffering. Working inevitably means experiencing failure—in terms of one's know-how, technique and control of the work process. Is suffering simply an unfortunate consequence of work? We shall attempt to show that in fact it is also at the origin of intelligence and ingeniousness. Which subjectivity? Assuming that we recognise what work owes to subjectivity, we must also reverse the question and ask ourselves what subjectivity (individual development) owes to work. We shall attempt to show that work constitutes a decisive challenge for subjectivity, one that can enhance that subjectivity (self-fulfilment) or, conversely, destroy it (mental pathology). Here, we shall evoke the questions raised by mental pathologies generated by the new forms of work organisation. Subjectivity between work and action? Work is not simply an individual experience. We always work for someone. Working always means encountering others in social relations, or in other words, relations of domination and servitude. Under what conditions do men and women who work agree to cooperate with each other? What conditions allow us to ward off the violence threatening to emerge from the social relations of work? Work offers what is perhaps the most ordinary opportunity to learn about living together (in Aristotle's sense) and democracy. But it can also give rise to the worst—the instrumentalisation of human beings and barbarity. (shrink)

ABSTRACT This paper reports on a multidisciplinary meeting held to discuss ethical issues in medical research in the developing world. Many studies, including clinical trials, are conducted in developing countries with a high burden of disease. Conditions under which this research is conducted vary because of differences in culture, public health, political, legal and social contexts specific to these countries. Research practices, including standards of care for participants, may vary as a result. It is therefore not surprising that ethical issues (...) emerge. This meeting sought to identify and discuss these issues from the perspectives of the many actors in such research, including community representatives, with a view to finding ethical and pragmatic solutions to these issues. Dialogue between these actors was also promoted, with a view to identifying the need to develop such dialogue in future. Drawing from the experiences of the speakers, the colloquium attempted to outline some answers to several key questions characterising the field today. Experiences related to epidemiologic research, vaccine trials, drug trials, diagnostic tests and to some fundamental ethical issues in health research. Speakers were from different countries, disciplines and professions. The meeting provided a forum for consultation and debate between different ethics actors. Both encouraging findings and challenges emerged. (shrink)
