1 Historique des projets ayant contribué au présent cahier thématique Ce numéro thématique porte témoignage des projets individuels et collectifs dans lesquels les éditeurs et l’éditrice invité-es ont été engagé-es ces dernières années. Les historiens de la pensée économique Nicolas Brisset et Raphaël Fèvre ont ainsi mené, à partir de 2018, un projet intitulé Expertise et Discipline Économiques sous Vichy (EDEV), ayant pour objectif d’interroger dans un même mouvement ce que Vichy a changé dans la structuration du savoir (et (...) de la discipline) économique en France, ainsi que la place de l’expertise des économistes dans le discours et les décisions du régime. L’historien des mathématiques Christophe Eckes a de son côté mis en place à partir de l’automne 2016 un séminaire portant spécifiquement sur les trajectoires de mathématiciennes et de mathématiciens sous l’Occupation, avec l’appui de ses homologues allemands Volker Remmert (université de Wuppertal) et Norbert Schappacher (universi...

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)

Dans cet article, nous entendons montrer que les principes d’invariance interviennent de manière essentielle pour caractériser les lois de la nature en physique. Pour ce faire, nous nous focaliserons sur les réflexions épistémologiques que Weyl et Wigner consacrent aux symétries. Nous proposerons une analyse conceptuelle de l’invariance en indiquant qu’elle permet de généraliser la première analogie de l’expérience de Kant (le principe de permanence de la substance). Nous analyserons de plus l’argument de Weyl selon lequel les principes d’invariance constituent des (...) connaissances a priori en un sens relativisé. Nous indiquerons pour finir qu’aux yeux de Wigner, les « symétries » constituent des conditions qui nous permettent de structurer notre compréhension de la réalité empirique. (shrink)

Nous entendons réexaminer tout un pan de l’histoire de la philosophie des sciences en France entre le milieu des années 1930 et l’immédiat après-guerre en nous appuyant sur les activités d’un réseau de scientifiques-philosophes qui s’est constitué autour de Gaston Bachelard, Jean-Louis Destouches et Ferdinand Gonseth après le congrès parisien de philosophie scientifique de septembre 1935. Ce réseau officialise sa rupture avec les positivismes logiques en organisant un colloque à Morgat en septembre 1938. Les activités de ce réseau se concrétisent (...) sous l’Occupation avec la publication en 1942 puis en 1944 de deux fascicules qui offrent une large place aux réflexions de Louis de Broglie, Jean-Louis Destouches et Paulette Destouches-Février en physique théorique, tout en traitant d’autres thématiques telles que le langage et le finalisme. Ces deux fascicules reflètent ponctuellement les engagements de l’un de ses membres, à savoir Jean Mariani, en faveur de la Révolution nationale. Si ce dernier est durement sanctionné à l’automne 1946, l’essentiel de ce réseau continue à jouer un rôle structurant en philosophie des sciences après la guerre et il gagne même en visibilité sur la scène philosophique internationale, grâce au soutien de Ferdinand Gonseth et de Stanislas Dockx.

À la fin du xixe siècle, avec l’achèvement des jalons d’un enseignement supérieur colonial en Algérie – création des écoles d’enseignement supérieur en Algérie en 1880 et fondation d’une université coloniale en terre algérienne, dotée d’un système facultaire en 1909 –, le paysage universitaire colonial prend son essor et se développe considérablement. La circulation d’universitaires métropolitains qui traversent la Méditerranée pour venir s’installer souvent durablement en Algérie, est le fait de botanistes, géologues, médecins et de mathématiciens. Cette contribution se focalise (...) sur l’analyse des circulations et des échanges dans le domaine des mathématiques entre la métropole et le territoire algérien. Elle propose d’examiner les évolutions de ces circulations à travers les trajectoires et les parcours d’universitaires qui ont soit effectué un séjour court en Algérie (le passage par l’École des sciences d’Alger pouvant servir de tremplin pour une carrière universitaire en métropole) ou qui ont effectué toute leur carrière universitaire et scientifique en Algérie. Cette focale, qui prend en compte la période 1868 à 1941, s’interroge en arrière-plan sur la contribution (ou non) du système colonial à la formation de jeunes mathématiciens algériens musulmans.

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.

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.

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.

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)

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.

Though only established as a discipline since the 1970s, philosophy of biology has already triggered investigations about its own history The Oxford handbook of philosophy of biology, Oxford University Press, New York, pp 11–33, 2008). When it comes to assessing the road since travelled—the research questions that have been pursued—manuals and ontologies also offer specific viewpoints, highlighting dedicated domains of inquiry and select work. In this article, we propose to approach the history of the philosophy of biology with a complementary (...) data-driven perspective that makes use of statistical algorithms applied to the complete full-text corpus of one major journal of the field—Biology and Philosophy—from its launch in 1986 up until 2017. By running text-mining and topic-modeling algorithms, we identified 67 key research topics that span across these 32 years. 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.

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.

Many researchers consider cancer to have molecular causes, namely mutated genes that result in abnormal cell proliferation (e.g. Weinberg 1998); yet for others, the causes of cancer are to be found not at the molecular level but at the tissue level and carcinogenesis would consist in a disrupted tissue organization with downward causation effects on cells and cellular components (e.g. Sonnenschein & Soto 2008). In this contribution, I ponder how to make sense of such downward causation claims. Adopting a manipulationist (...) account of causation (Woodward 2003), I propose a formal definition of downward causation, and discuss further requirements (in light of Baumgartner 2009). I then show that such an account cannot be mobilized in support of non-reductive physicalism (contrary to Raatikainen 2010). 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).

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.

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)

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)

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)

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)

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)

Artificial stimulation of the peripheral vestibular system has been shown to improve ownership of body parts in neurological patients, suggesting vestibular contributions to bodily self-consciousness. Here, we investigated whether galvanic vestibular stimulation interferes with the mechanisms underlying ownership, touch, and the localization of one’s own hand in healthy participants by using the “rubber hand illusion” paradigm. Our results show that left anodal GVS increases illusory ownership of the fake hand and illusory location of touch. We propose that these changes are (...) due to vestibular interference with spatial and/or temporal mechanisms of visual-tactile integration leading to an enhancement of visual capture. As only left anodal GVS lead to such changes, and based on neurological data on body part ownership, we suggest that this vestibular interference is mediated by the right temporo-parietal junction and the posterior insula.

La vie est-elle un phénomène émergent ? Traduit-elle l'apparition de propriétés nouvelles au niveau d'un tout, qui seraient irréductibles aux propriétés et à l'organisation des composants de ce tout, ou encore imprédictibles à partir de ces mêmes éléments ? Développée à la charnière des XIXe et XXe siècles comme alternative aux deux approches antinomiques du vivant que sont le vitalisme et le mécanisme, la notion philosophique d'émergence connaît aujourd'hui de nouveaux développements : avec la prise de conscience de la complexité (...) du vivant, un nouveau discours émergentiste refait surface en biologie et dans le champ scientifique des origines de la vie. Que signifie la notion d'émergence lorsqu'elle s'applique à l'apparition de la vie sur Terre ? Quelles sont sa pertinence et sa portée ? Dans ce livre, Christophe Malaterre propose une clarification conceptuelle de la notion philosophique d'émergence ; il en défend une conception épistémique et contextuelle, adossée à la notion d'explication. En s'inspirant des travaux les plus contemporains sur les origines de la vie, il montre que, selon le contexte épistémique dans lequel le phénomène est évalué, la qualification de l'apparition de la vie comme émergente est, ou non, justifiée. Il défend alors la thèse selon laquelle la caractérisation émergentiste de l'apparition de la vie n'est qu'une conséquence temporaire des limites de nos connaissances scientifiques. (shrink)

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)

The author argues the following hypothesis: the medical clinic is an experimental practice, in the sense given to this term by Claude Bernard, and the clinic is its specific laboratory. Its object is not the disease, but the patient. Careful examination of the clinic attests to its very close proximity to the experimental method, and the comparison also raises a number of difficulties. The main obstacle arises from the specificity of medicine, which involves treating individual human subjects whose words cannot (...) be suppressed. Its main challenge is to combine a linguistic practice with an experimental method. (shrink)

The plurality of definitions of life is often perceived as an unsatisfying situation stemming from still incomplete knowledge about ‘what it is to live’ as well as from the existence of a variety of methods for reaching a definition. For many, such plurality is to be remedied and the search for a unique and fully satisfactory definition of life pursued. In this contribution on the contrary, it is argued that the existence of such a variety of definitions of life undermines (...) the very feasibility of ever reaching a unique unambiguous definition. It is argued that focusing on the definitions of specific types of ‘living systems’ – somehow in the same way that one can define specific types of ‘flying systems’ – could be more fruitful from a heuristic point of view than looking for ‘the’ right definition of life, and probably more accurate in terms of carving Nature at its joints.

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)

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.

Christophe Bruchansky asks if we’re living in a global themepark. -/- Walt Disney World opened in Florida in 1971. It was the second theme park built by Disney, the first being Disneyland in California in 1955. Disney World is not one theme park, but a group of four theme parks, two water parks, and many hotels, all together in Orlando. It is one of the most visited attractions in the world, and represents far from merely an American phenomenon. Disney (...) theme parks are now located in Paris, Tokyo and Hong Kong, and a new park has recently been announced for Shanghai. But what is a Disney theme park? Is it a utopia? Is it a heterotopia – a concept defined by French philosopher Michel Foucault? Or is it something else? As you will see from this article, understanding Disney World requires a profound reflection on culture, history and reality. (shrink)

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.

If the desert was long perceived as a hostile and inhospitable territory, it was gradually conquered during the 20th century by the practice of sports and leisure activities. The aim of this articl...

Le déficit d’explicabilité des techniques d’apprentissage machine (AM) pose des problèmes opérationnels, juridiques et éthiques. Un des principaux objectifs de notre projet est de fournir des explications éthiques des sorties générées par une application fondée sur de l’AM, considérée comme une boîte noire. La première étape de ce projet, présentée dans cet article, consiste à montrer que la validation de ces boîtes noires diffère épistémologiquement de celle mise en place dans le cadre d’une modélisation mathématique et causale d’un phénomène physique. (...) La différence majeure est qu’une méthode d’AM ne prétend pas représenter une causalité entre les paramètres d’entrées, qui peuvent être de plus de haute dimensionnalité, et ceux de sortie. Nous montrons dans cet article l’intérêt de mettre en œuvre les distinctions épistémologiques entre les différentes fonctions épistémiques d’un modèle, d’une part, et entre la fonction épistémique et l’usage d’un modèle, d’autre part. Enfin, la dernière partie de cet article présente nos travaux en cours sur l’évaluation d’une explication, qui peut être plus persuasive qu’informative, ce qui peut ainsi causer des problèmes d’ordre éthique.

Christophe Perrin ABSTRACT: What does it mean to ‘make love?’ Or, rather, what are we doing when we ‘make love?’ This expression makes of love a praxis on which the history of philosophy, rather modest, has said little. Philosophy has certainly evoked love, but always as a passion, an emotion, a feeling, and rarely as an...

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)
