Although "intrasexual selection" has been accepted as the mechanism by which males evolve elaborate secondary sexual traits which are used in aggressive contests, the importance of "intersexual selection" as a mechanism by which males have acquired exaggerated traits to display to females during courtship was less readily accepted. In spite of this scepticism, several genetic models have supported the latter idea, and many empirical studies showed that females were generally more discriminating in mate choice than males, because of differences in (...) relative investment between sexes. Nowadays, this idea is reinforced by various concepts (parental investment, potential reproductive rate, environmental potential for polygamy...) which stress that the strength of sexual selection is related to many interdependent factors, such as mating systems, resource distribution (food, habitat, mate), life history and other ecological characteristics. The case of Salmonids is presented here to show how novel information on sexual selection has contributed to the understanding of the plasticity of breeding patterns in the context of evolutionary biology.

Es werden Beziehungen zwischen den Begriffen der potentia, der Existenz und der besten aller möglichen Welten untersucht.

Gallicagram est un nouvel outil de lexicométrie, fondé notamment sur les archives océrisées de la Bibliothèque nationale de France et sur celles du journal Le Monde ; il dénombre dans le corpus choisi et pour une période donnée les occurrences d’un mot ou d’un syntagme, et offre différents modes de visualisation des données obtenues. Ce logiciel mérite à plusieurs titres d’être investi par les chercheurs : outre le volume des données qu’il exploite, suffisant pour fonder des analyses lexicométriques depuis le (...) XVIIe siècle jusqu’à nos jours, Gallicagram a sur son concurrent immédiat, Ngram Viewer, l’avantage d’une transparence très supérieure et d’une structure plus constante au cours du temps. L’article présente Gallibase, son extension qui lui applique les outils de la statistique textuelle – en particulier les analyses factorielles et arborées. Il illustre son potentiel et insiste sur l’intérêt spécifique des corpus de presse, qui permettent des études sur périodes courtes. (shrink)

Are doubt and suspension of judgment similar attitudes? In the burgeoning literature on suspension of judgment, the notion of doubt is curiously absent. This paper aims to argue for the plausibility of an identity claim, which I term the “No-Difference View.” This view suggests that there is no substantial difference between being in doubt and suspending judgment. The argument will draw on historical and systematic considerations that support the No-Difference View as a plausible view within the logical space of positions.

Cet article vise à élucider la nature de l'enquête. Je présente tout d'abord les desiderata communs à toute théorie de l'enquête. Je catégorise ensuite l'enquête comme un processus structuré en me concentrant sur ses composantes essentielles : des attitudes de questionnement guidant des actions. Enfin, je me penche sur l'objection récente selon laquelle les attitudes de questionnement ne sont pas nécessaires à l'enquête. Je défends la thèse selon laquelle l'enquête est un processus structuré essentiellement constitué d'attitudes de questionnement ayant deux (...) rôles fonctionnels précis, soit d'initier et de guider le déploiement de capacités cognitives en vue d'un but épistémique.

Laughter and yawning can both occur spontaneously and are highly contagious forms of social behavior. When occurring contagiously, laughter and yawning are usually confounded with a social situation and it is difficult to determine to which degree the social situation or stimulus itself contribute to its contagion. While contagious yawning can be reliably elicited in lab when no other individuals are present, such studies are more sparse for laughter. Moreover, laughter and yawning are multimodal stimuli with both an auditory and (...) a visual component: laughter is primarily characterized as a stereotyped vocalization whereas yawning is a predominantly visual signal and it is not known to which degree the visual and auditory modalities affect the contagion of laughter and yawning. We investigated how these two sensory modalities contribute to the contagion of laughter and yawning under controlled laboratory conditions in the absence of a social situation that might confound their contagion. Subjects were presented with naturally produced laughter and yawning in three sensory modalities, and we recorded their reaction to these stimuli. Contagious responses differed for laughter and yawning: overall, laughter elicited more contagious responses than yawning, albeit mostly smiling rather than overt laughter. While the audio-visual condition elicited most contagious responses overall, laughter was more contagious in the auditory modality, and yawning was more contagious in the visual modality. Furthermore, laughter became decreasingly contagious over time, while yawning remained steadily contagious. We discuss these results based on the ontogenetic and phylogenetic trajectories of laughter and yawning. (shrink)

Benoit Mathot À partir du cadre théorique de la décoïncidence proposé par le philosophe François Jullien, cet article explore les enjeux d’humanisation des soins médicaux, ainsi que l’introduction de la dimension spirituelle dans la prise en charge des patients. Il revient enfin sur le dialogue possible entre ces réflexions contemporaines et les considérations du théologien luthérien Paul Tillich sur la santé.

Taking regular walks when living with Parkinson’s disease has beneficial effects on movement and quality of life. Yet, patients usually show reduced physical activity compared to healthy older adults. Using auditory stimulation such as music can facilitate walking but patients vary significantly in their response. An individualized approach adapting musical tempo to patients’ gait cadence, and capitalizing on these individual differences, is likely to provide a rewarding experience, increasing motivation for walk-in PD. We aim to evaluate the observance, safety, tolerance, (...) usability, and enjoyment of a new smartphone application. It was coupled with wearable sensors and delivered individualized musical stimulation for gait auto-rehabilitation at home. Forty-five patients with PD underwent a 1-month, outdoor, uncontrolled gait rehabilitation program, using the BeatWalk application. The music tempo was being aligned in real-time to patients’ gait cadence in a way that could foster an increase up to +10% of their spontaneous cadence. Open-label evaluation was based on BeatWalk use measures, questionnaires, and a six-minute walk test. Patients used the application 78.8% of the prescribed duration and enjoyed it throughout the program. The application was considered “easy to use” by 75% of the patients. Pain, fatigue, and falls did not increase. Fear of falling decreased and quality of life improved. After the program, patients improved their gait parameters in the six-minute walk test without musical stimulation. BeatWalk is an easy to use, safe, and enjoyable musical application for individualized gait rehabilitation in PD. It increases “walk for exercise” duration thanks to high observance.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT02647242. (shrink)

English summary: Benoit Spinosa presents a much needed French biography and study of the English philosopher Thomas Hobbes (1588-1679). Spinosa discusses Hobbes controversial Leviathan and his unique understanding of the political machine in the Early Modern period. French description: Thomas Hobbes (1588-1679), philosophe anglais, doit sa celebrite au Leviathan, a une conception de la souverainete politique longtemps jugee monstrueuse. Par-dela contresens et accusations, Hobbes est bien le premier penseur de la modernite a avoir voulu maitriser la machination politique comme la (...) science galileenne controlait les mecanismes naturels. Il eut l'idee d'un systeme global, allant du corps en general, chose physique, au corps politique engendre par la puissance humaine d'artifice, en passant par le corps humain, objet d'une anthropologie nouvelle qui s'appuie sur une vision originale du desir. Sans le langage, la science des corps serait pourtant impossible. C'est par l'imposition de noms, que les hommes peuvent se soustraire aux aleas de l'experience, construire des chaines de raisonnement et envisager ainsi les choix politiques que la necessite laisse ouverts. Dans un monde expose aux violences de la revolution et des conflits religieux, Hobbes a cherche les moyens rationnels de resister aux folies de l'histoire. La question n'est visiblement pas close.

This paper studies how in his Theory of Moral Sentiments Adam Smith answered to Mandeville on the role of pride and vanity in the economic and social dynamics of commercial societies. We show why vanity supersedes pride in his analysis and how he offers a more positive view of these two passions. We study in particular the economic and social consequences of pride and vanity and describe the psychological foundations of excessive self-esteem that these passions entail.

Afin de clarifier la réalité elle-même, Nietzsche rapporte généalogiquement le « conatus » spinoziste à une volonté de statisme à laquelle il oppose la dynamique expansive de la volonté de puissance. Pourtant, on peut montrer que Nietzsche rejette moins la conservation qu’il ne la réinterprète dans l’ordre d’une grandeur à produire, indissociable du tragique.

Quelle est aujourd’hui la place des Espaces-Rencontre parmi les interventions qui portent sur les relations enfants-parents, notamment dans les situations de rupture? Quelle est la spécificité de l’action des Espaces-Rencontre et d’où tiennent-ils leur identité? Quelle place occu-pent-ils dans le champ judiciaire, la santé mentale, le travail social? Et quel enseignement tirer de cette analyse pour l’avenir des Espaces-Rencontre? L’auteur, sociologue et chercheur, fait le point pour les dix ans du Point-Rencontre de Lille.

La présente étude rassemble les passages de l’Ab Vrbe condita de Tite-Live où un terme lié au rire est associé à un discours ou à une parole rapportée, afin de les confronter aux vues exprimées par Cicéron et Quintilien sur le rire en contexte rhétorique.

It is clear enough that utilitarianism contributed to the softening of many penal systems in the world by arguing that very cruel punishments should be excluded every time a less cruel one would be just as effective. But does utilitarianism as such oppose the death penalty ? It is well known that Beccaria and Bentham criticized capital punishment on utilitarian grounds. But the fact that John Stuart Mill held a speech in favour of the death penalty at the House of (...) Commons in 1868 suggests that there is no necessity for a utilitarian thinker to oppose it. Otherwise, it would be possible to claim that John Stuart Mill betrayed, so to speak, the principle of utility by defending such a punishment. But nothing, it seems, allows us to say so. On the contrary, we would like to suggest that Mill’s disagreement with Bentham and Beccaria originates from his own empirical judgement on the following question : is death penalty the most cruel punishment for murder ? In other words, whether we like it or not, there is no way we can hold that Mill was less faithful than Beccaria and Bentham to the principle of utility when supporting the death penalty. (shrink)

A few months after the publication of the French translation of his book Causing Death and Saving Lives, Jonathan Glover was kind enough to return to some of the theses defended in this book. In forty years, this work has become a classic of applied ethics in the English-speaking world. Glover tackled a series of questions involving the lives of men and women, including abortion, infanticide, suicide, euthanasia, the death penalty and war. We asked him here about the method he (...) considers the best in moral philosophy, and returned to his criticism of certain dominant ideas at the time. Jonathan Glover also discusses some of the positions of his former students Peter Singer and Jeff McMahan. (shrink)

L'article explore la notion wébérienne de «domination rationnelle» comme outil pour analyser les rapports entre les efforts de gestion des populations indigènes par l'État colonial, et le développement d'une forme spécifique de rationalité scientifique, prenant pour objet ces populations: les savoirs anthropologiques. En s'appuyant sur le cas de l'Afrique coloniale française, on s'efforce de montrer comment les dimensions d'instrumentation (avec la production d'instruments d'identification et de compréhension) et de légitimation sont essentielles dans l'émergence de savoirs sur les sociétés et les (...) cultures indigènes, d'abord au sein des appareils administratifs, mais aussi dans les institutions savantes métropolitaines. L'appui au développement de la science de l'homme se fait dans le cadre de projets de « rationalisation » de la colonisation qui rapprochent des savants et des réformateurs liés à l 'École coloniale, voulant redéfinir la profession d'administrateur colonial comme «spécialiste des indigènes».

Christianism often mentions perfumes. Its liturgy based on Scripture uses incense and balm. A reading from the Bible and the lives of saints reveals many extraordinary perfumes (“odours of sanctity”). The Virgin Mary holds extreme importance among saints and it is quite common to see her spreading miraculous fragrances. These are subtle, discrete but pleasant signals from Heaven. They are sent to everyone in order to convert non‑believers or turn back believers to the faith in God. The divine origin of (...) perfumes is tied up with the memories and hopes from Paradise. It marks bodies escaping from death and entering into eternal life. (shrink)

Cette étude considére le § 301 du Gai Savoir, à partir du § 98 même ouvrage. Dans le sillage de la «nouvelle justice» brièvement présentée dans le § 289, ce § 301 remaine en profondeur l'opposition traditionelle entre l'actif et le contemplatif; suivre pas à pas ect aphorisme permet ainsi de constituer «l'homme juste» en problime qui est cet «homme juste»? Brutus? Shakespeare? Le «poète»? Et donc: comment appréhender la «nouvelle justice»?Diese Untersuchung befasst sich mit dem § 301 der Fröhlichen (...) Wissenschaft, gestützt auf § 98 desselben Werks. Im Zuge der "neuen Gerechtigkrit", die in § 289 kurz dargestellt worden war, formt dieser § 301 den traditionellen Gegensatz zwischen dem Aktiven und dem Contemplativen grundlegend um. Die schrittweise Betrachtung dieses Aphorismus erlaubt dann, den "gerechten Menschen" zum Problem zu machen: wer ist dieser "gerechter Mensch"? Brutus? Shakespeare? Der "Dichter"? Und somit: wie ist die "neue gerechtigkeit" aufzufassen? This articles considers § 301 of The Gay Science in the light of § 98 of the same work. In the wake of the "new justice" briefly presented in § 289, § 301 is an in-depth reconsideration of the traditional opposition between the active and the contemplative; thus a step by step approach to this aphorism allows one to establish "the just man" as a problem: who is that "just man"? Brutus? Shakespeare? The "poet"? Hence, how is the notion of "new justice" to be grasped? (shrink)

Throughout the manuscript of the Pensées and in other writings, Pascal crisscrosses his research on what the art of writing achieves and entails, on the one hand, and on the way to read and interpret the Holy Scriptures, on the other hand. Reading and writing practices are critically interwoven. This article offers a synthesis on Pascal’s reflexive account of such practices. After a summary of previous findings on the subject, it examines Pascal’s approach to (a) the rules that govern scriptural (...) interpretation; (b) the techniques of persuasion; and (c) the way to ground an instituted body, an expression by which we refer to a textual corpus, a political society, or a community of believers.

During the past few years, the IRBIT domain has emerged as an important add‐on of S‐adenosyl‐L‐homocystein hydrolase (AHCY), thereby creating the new family of AHCY‐like proteins. In this review, we discuss the currently available data on this new family of proteins. We describe the IRBIT domain as a unique part of these proteins and give an overview of its regulation via (de)phosphorylation and proteolysis. The second part of this review is focused on the potential functions of the AHCY‐like proteins. We (...) propose that the IRBIT domain serves as an anchor for targeting AHCY‐like proteins towards cytoplasmic targets. This leads to regulation of (i) intracellular Ca2+ via the inositol 1,4,5‐trisphosphate receptor (IP3R), (ii) intracellular pH via the Na+/HCO3− cotransporters (NBCs); whereas inactivation of the IRBIT domain induces (iii) nuclear translocation and regulation of AHCY activity. Dysfunction of AHCY‐like proteins will disturb these three important functions, with various biological implications. BioEssays 30:642–652, 2008. © 2008 Wiley Periodicals, Inc. (shrink)

Dans une note de son ouvrage consacré à Henry, P. Audi affirme qu’« il n’y a pas de philosophie de l’histoire à proprement parler chez Henry ». Nous ambitionnons de rappeler ici que Henry a néanmoins donné un contenu au concept d’histoire et posé les conditions épistémologiques pour construire une phénoménologie radicale de l’histoire. Cette thématique, il est vrai, est généralement ignorée de la littérature secondaire. À son corps défendant, on est obligé de reconnaître que la question de l’...

Descola’s work has profoundly renewed ecological thought by suggesting that the global planetary crisis is linked to the ‘naturalist ontology’, by which modern Westerners distance themselves from non-humans. This article proposes to re-read Descola with Marx in order to critically assess question the genesis of this ontology. Rather than looking to the history of ideas in search of what prepared this naturalism, a close reading of Marx allows to hypothesise a practical origin of naturalism, in the worldly occupations that make (...) up ‘abstract labour’. By shedding light on the practical ontogeny of naturalism, we emphasize that the Marxian analysis of capitalism remains highly needed for thinking about and living through the ecological crisis.
