What role does non-genetic inheritance play in evolution? In recent work we have independently and collectively argued that the existence and scope of non-genetic inheritance systems, including epigenetic inheritance, niche construction/ecological inheritance, and cultural inheritance—alongside certain other theory revisions—necessitates an extension to the neo-Darwinian Modern Synthesis (MS) in the form of an Extended Evolutionary Synthesis (EES). However, this argument has been challenged on the grounds that non-genetic inheritance systems are exclusively proximate mechanisms that serve the ultimate function of calibrating organisms (...) to stochastic environments. In this paper we defend our claims, pointing out that critics of the EES (1) conflate non-genetic inheritance with early 20th-century notions of soft inheritance; (2) misunderstand the nature of the EES in relation to the MS; (3) confuse individual phenotypic plasticity with trans-generational non-genetic inheritance; (4) fail to address the extensive theoretical and empirical literature which shows that non-genetic inheritance can generate novel targets for selection, create new genetic equilibria that would not exist in the absence of non-genetic inheritance, and generate phenotypic variation that is independent of genetic variation; (5) artificially limit ultimate explanations for traits to gene-based selection, which is unsatisfactory for phenotypic traits that originate and spread via non-genetic inheritance systems; and (6) fail to provide an explanation for biological organization. We conclude by noting ways in which we feel that an overly gene-centric theory of evolution is hindering progress in biology and other sciences. (shrink)

"Artists are trying to move away from the influence of competitive corporate culture that has increasingly defined art as an abrasive urban career. Artists are trying to replace this with the humbler notion of art as a practice, as a mindful way of life, consisting of consciously creative gestures, visible and invisible, large and small. Art practice is a private and public, selfless and generous, creative life process resulting in a conscious cultural product." "Walking Art Practice" brings together the author's (...) experiences as a monk, performance artist, social choreographer and educator. It serves as a provocation, walkers' manifesto, and teaching guide for walking as a mindful cultural activity and as mindful cultural activism. It is an inspirational text for artists, art students and anyone who loves to walk. Ernesto Pujol combines elements from an art book, field journal and walkers' manifesto. It is a text for performative artists, art students, and all who walk as cultural activism. This book is an invitation to: Rethink what it means to walk and explore different ways in which to walk as: a cultural practice; a meditative practice; a radical practice; art; healing; and social engagement; Reconsider how to attend to the inner and outer landscape whilst walking; Treat walking as a performance resource; Walk as an everyday pilgrimage; Walk slowly, walk in and with awareness, walk with and without skill, walk to regain and to lose.

Nicolas Pujol | : L’auteur montre, à partir d’une analyse critique de la catégorie de « sacré », que le modèle d’intégration de la spiritualité à l’hôpital proposé par Kenneth I.

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 examines the astrological and religious thinking of Moshe ben Nahman (also known as Ramban or Nahmanides) and the intellectual connections in this field with two of the most outstanding Christian thinkers of his time, Ramon Llull and Arnau de Vilanova. Nahmanides, like many medieval scholars, admitted an astral influence, but he did not accept astrology as a divinatory science. He incorporated astrological doctrines in his exegetical works, assuming that Israel is not determined by any star because it only (...) responds to God. Yet the study of medieval medicine and its application cannot be separated from astrology practice because it was considered that the stars had a direct influence not only on the development of the human body, from birth to death, but also in the disease processes which affect it. Ramban and his disciple Solomon ben Adret accepted and practiced astrological medicine. Llull and de Vilanova also devoted themselves to this discipline. All of them agree on the influence of the stars on humankind but condemned astral magic. Like Ramban, Llull rejects other astrological methods considered non-scientific in his time, such as prediction through horoscope. Thus, these thinkers tried to develop an astrology that was not in contradiction with divine omnipotence or free will. (shrink)

This book revisits the encounter between Chinese and Western philosophy while unfolding questions about the way "comparative philosophy" is conducted today. In the vulgate of intellectual history, "Western thought" has constructed a substantialist view of reality that puts "relations" and "processes" into a subordinate position. The same view explains for the primacy given to the autonomy of individual beings. In contrast, according to the same vulgate, Chinese thought has been mainly stressing the fluidity of all phenomena and forms of life (...) so as to best adapt to their overarching patterns. I label such vision the Disneyland of comparative philosophy. It deciphers texts, partly in function of concepts that it extracts from them, partly according to notions that are superimposed over these texts. The two first chapters are focused upon the Western version of the "Disneyland of comparative philosophy." The third chapter shifts to Chinese narratives about local, comparative and global philosophies. In contrast to these approaches, the fourth chapter offers a blueprint as to the way to engage different philosophical traditions into tasks they define and share together. A last chapter presents four cases of ongoing transcultural philosophical dialogues and the promises they bear. Once it develops outside pre-formatted narratives, the web shaped by our philosophies and wisdoms suggests the outlines of a world that we could inhabit together. (shrink)

This article argues for the need to recover the concept of political myth in order to understand the crucial phenomena of our epoch. By drawing on Blumenberg’s philosophical reflections on myth, it proposes to understand political myth as the continual process of work on a common narrative by which the members of a social group can provide significance to their political conditions and experience. In order to show how this understanding of political myth can throw light on important aspects of (...) contemporary politics, the article analyses the work on one of the most conspicuous political myths of our time: the clash of civilizations. By reconstructing the mechanisms through which this myth works, the article shows how a paradigm that has been strongly criticized as too simplistic and scientifically inadequate could have turned into a successful political myth, i.e. into a self-fulfilling prophecy.

Réfléchir à l’idée de justice et de prise en compte des intérêts, notamment économiques, ouvre un champ d’étude considérable, même en prenant comme point de départ l’analyse juridique. Aussi pour tenter de circonscrire l’objet de cette recherche, le choix a été fait de partir d’une situation, provoquant la mise en tension de l’idée même de justice d’une manière originale et d’envisager une réponse juridique nouvelle. A cet égard, partir des catastrophes industrielles s’est imposé à plusieurs titres. D’une part, le phénomène (...) est mondial puisque des catastrophes ont eu lieu tant dans des pays développés qu’en développement. D’autre part, il questionne l’idée de justice de manière complexe car les conséquences ne sont pas univoques et le profil des victimes est très divers. Enfin, les modalités d’intervention juridique pour réguler ces situations poussent à envisager un cadre transnational d’intervention cohérent avec la portée des catastrophes industrielles. Néanmoins, cette réglementation, au sein de traités négociés entre pays et qui relève du droit international économique ne fait pas figure d’évidence. Pour dépasser l’horizon national en matière de normes juridiques, il convenait donc d’identifier un concept à même de le justifier : la justice socio-environnementale. (shrink)

L’article « Droit naturel » de Diderot est sans doute l’un des articles les plus lus et les plus commentés de l’Encyclopédie. Certains critiques y voient une rupture décisive avec le droit naturel moderne, d’autres considèrent au contraire que Diderot s’efforce d’en donner une lecture personnelle et non métaphysique. La plupart s’accordent à y reconnaître les symptômes d’une « crise », qui n’est pas sans annoncer celle qui caractérisera un peu plus tard la pensée de Rousseau. Qu’il y ait une (...) « crise » du droit naturel dans cet article, personne ne le contestera. Plutôt que de considérer ce texte comme une simple réfutation, on peut se demander si Diderot ne cherche pas à refonder le droit naturel en posant autrement la question de sa « naturalité », à travers une série de propositions indécidables. Notre idée est que l’article de Diderot aménage et discute vigoureusement certains aspects de ce droit sans en récuser sa légitimité. Il introduit notamment la notion de volonté générale, absente des théories jusnaturalistes, pour proposer une nouvelle théorie des droits et des devoirs dont la fonction est d’ouvrir le champ de la morale. L’implicite de ce texte serait en effet le souci de donner les moyens conceptuels permettant de sortir d’un régime de prescription trop contraignant qui fait traditionnellement reposer la morale sur toute une série d’interdits. En confiant notamment à la « volonté générale » la charge de « fixer les limites de tous les devoirs », Diderot défait le carcan dans lequel s’enferme à des degrés divers toute morale déontique.

How is it possible for deontic evaluations of beliefs to be appropriate if we do not have voluntary control over our beliefs? Gaultier argues that we should reject the claim that we can have indirect control over beliefs in virtue of the basic voluntary control we have over our actions. We have another kind of indirect control over beliefs: we can demonstrate doxastic strength or, on the contrary, doxastic weakness when forming our beliefs. That is, we can resist or, on (...) the contrary, fail to resist the influence of some of our conative attitudes. And in the same way that we take our actions to be open to blame when they result from having demonstrated weakness of will even though this does not consist in doing something at will, we take our beliefs to be open to blame and hence subject to deontic evaluation, when they result from having demonstrated doxastic weakness even though this does not consist in doing something at will.

Following a common assumption, when one inquires into a question, one has an inquisitive attitude towards it. More precisely, I shall assume that there is an inquisitive attitude towards Q that all of those who inquire into Q have in common and in virtue of which they can be said to be in an inquisitive state of mind towards Q. This paper is about the nature of this attitude. I elucidate it by examining whether it boils down to doubt, curiosity, (...) epistemic desire, or wondering. I shall do this by examining whether having these attitudes is necessary and sufficient for being in an inquisitive state of mind. The test will prove negative for the first three, but the case of wondering is more complex. (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.

In this book, Benoît Dubreuil explores the creation and destruction of hierarchies in human evolution. Combining the methods of archaeology, anthropology, cognitive neuroscience and primatology, he offers a natural history of hierarchies from the point of view of both cultural and biological evolution. This volume explains why dominance hierarchies typical of primate societies disappeared in the human lineage and why the emergence of large-scale societies during the Neolithic period implied increased social differentiation, the creation of status hierarchies, and, eventually, (...) political centralisation.

In this special issue on Jonathan Glover and his applied ethics, I asked Jeff McMahan to review the influence of Questions of Life and Death, published forty years ago in its original version.

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.

Alterations in the gut microbiome have increasingly been implicated in driving obesity and its associated diseases, but underlying mechanisms remain poorly defined. Herein, in addition to reviewing the field, we hypothesize that a highly significant causative factor of such inflammatory disease‐associated microbiome alterations is a more aggressive microbiota that encroaches upon its host, with components having high potential to activate host pro‐inflammatory gene expression in a manner that drives metabolic disease. We further hypothesize that a range of societal changes, including (...) use of antibiotics and increasing consumption of food additives, have provoked such microbiota aggression and, consequently, may be contributing factors to the increased incidence of obesity and its associated diseases.

The current SARS-CoV-2 crisis raises questions about the challenges faced by nation states and international organisations in offering a coordinated international response to the pandemic, and reveals the great vulnerability of European countries, which are implementing lockdown measures and imposing restrictions on international travel, for the most part on a unilateral basis. Such measures run counter to the prevailing approach of the previous two centuries that developed an international public health space. This article examines the measures adopted by European states (...) in order to contain 19th-century cholera pandemics, which took shape through the development of an international maritime quarantine system, based primarily on the implementation of national regulations and local decision-making. This regime was quickly viewed as ineffective and out of step with liberal ideas that urged a “laissez-faire” approach to public health matters. In its stead, a long-term trend developed towards easing quarantine measures. Nation states supported the internationalisation of the fight against pandemics, which chiefly consisted of externalising quarantine measures to the East in order to eliminate them in Europe. This process was based on a subtle dialectical relationship between the construction of an international public health space and the affirmation of state sovereignty, and continued into the 20th century with the progressive creation of international institutions responsible for advancing global health.

O revezamento de protagonismo de um dos Três Poderes, em determinado momento histórico, é sazonal; acarretando o aperfeiçoamento de mecanismos que recomponham o equilíbrio (freios e contrapesos - checks and balances).

The recent literature on social norms has stressed the centrality of emotions in explaining punishment and norm enforcement. This article discusses four negative emotions (righteous anger, indignation, contempt, and disgust) and examines their relationship to punitive behavior. I argue that righteous anger and indignation are both punitive emotions strictly speaking, but induce punishments of different intensity and have distinct elicitors. Contempt and disgust, for their part, cannot be straightforwardly considered punitive emotions, although they often blend with a colder form of (...) indignation to favor low-cost, indirect, and collective forms of punishment such as mockery, exclusion, and ostracism.

Normal 0 21 Minha intenção é a de mostrar como uma leitura cética dos diálogos socráticos de Platão permite explicar alguns impasses nos quais resulta a interpretação dogmática desses diálogos. Enumero aqui, de maneira programática, os elementos que permitirão sustentar que, nos diálogos de juventude, Platão desenvolveu uma lógica que conduz a uma posição forte sobre os limites do conhecimento e do intelectualismo. Essa interpretação se inspira em traços dominantes do ceticismo de Arcesilau (séc. III a.C.). Mostrarei como os diálogos (...) de Platão podem ser lidos como a inspiração por trás da posição de Arcesilau quando este afirma que seria preciso suspender o julgamento e, na falta de certeza, seguir o que é razoável ( eulogon ). De uma parte, o estudo do estatuto paradoxal da ignorância socrática e do papel do oráculo na Apologia permite discernir o funcionamento de uma lógica propícia a gerar aporias. De outra parte, a análise do problema da virtude-ciência no Protágoras e no Laques permite exibir os mecanismos de uma argumentação cuja conclusão é a impossibilidade de defender hic e nunc uma ética estritamente intelectualista.

The following article is the result of a collaboration between a painter and a woman philosopher. They worked previously on an experimental documentary film about objects and art objects, which was realized at Palais de Tokyo. The painter had illustrated in black and white fictions of philosophy, written during a festival on lost films organized by UNdocumenta in South Korea, and then he made photographs of oil paintings of the English translation. This article about painting and philosophical ethics is their (...) first common text. It aims to show that there is no interdiscipline or passage known between the philosophical work and the painting. The philosopher can not imitate the recognition of the painter nor the painter to repair the philosophical non-encounter. The question then is: What can ethics in this non-symmetrical space? Rather than being a product of philosophy, it is what organizes this space between recognition and non-encounter. It is an ethics for philosophy, rather than the other way around. Ethics force to greet the other philosophers without the grudge of the loss necessary to the invention and allows the painter to know the distances that make him feel the recognition. This ethical space is unknown and can not be covered by the artist's philosophy of access or pre-nomination by indexes. Ethics is this unknown, i.e. it is a sense-without-sign, it is without rules-said but process of indexation and acceptance of the loss. (shrink)

À partir d’une rencontre avec la «sino-théologie», l’auteur tente une double ressaisie: du rapport entre sagesse et révélation tel qu’il nous est loisible de le penser aujourd’hui; du régime de la sagesse chinoise et, par extension, d’autres expressions de la «sagesse des peuples» à la lumière d’une herméneutique renouvelée. Il suggère quelques chemins par lesquels «sagesse» et «révélation» peuvent être comprises comme des catégories «ouvertes», ne recevant sens et pertinence que d’être référées à une constante reprise à neuf. En parallèle, (...) le régime épistémologique de la sagesse chinoise se découvre avoir vocation à former un type d’homme en qui l’humanisation est inséparable du sens de la perte et de la quête, et du retournement des sens vers l’intérieur. Le passage par la tradition chinoise nous permet de saisir comment la catégorie de «révélation» ne fait sens qu’en relation à une «sagesse» qui seule en permet la réception par l’interprétation vivante dont elle fournit la trame.

The discourse of tragedy has significant value in a military context, reminding us of the temptations of hubris, the prevalence of moral dilemmas, and the inescapable limits of foresight. Today, however, this discourse is drawn upon too heavily.

The tragedy discourse, when wrongly applied by policymakers and the media, indulges the very hubris the (...) tragic recognition is intended to caution against. This article clarifies the limits of “tragedy” in the context of military violence and argues for a renewed focus on political responsibility. (shrink)

The progressive dominance of historical-critical methods in the reading of ancient Chinese classics has led scholars to privilege micro levels of textual analysis. Consequently, the question as to whether laws of composition could be identified in this corpus has often been ignored, or considered irrelevant. Working on Chinese number symbolism as well as on rules governing “ring composition” in other cultural contexts, this article aims at fashioning anew the question of the possibility of an ancient Chinese “structural rhetoric” and at (...) envisioning the patterns that might have governed it. It specifically applies the approach it propounds to Huainanzi 淮南子, showing how numerology frames its structure and argument, the text being built after the image of the “roundness” of the Way and of the Ruler. It then endeavors to apply these results to the unearthing of “inter-structural” patterns that would help us to locate Huainanzi, Lüshi Chunqiu 呂氏春秋, the versions at hand of Zhuangzi 莊子, Lunyu 論語, or yet Laozi 老子 into a textual universe that shares correlated rhetorical features.

Theories of knowledge as credit for true belief, or as cognitive achievement, have to face the following objection: in the famous Barn façades case, it seems that the truth of Barney's belief that he is in front of a barn is to be explained by the correct functioning of his cognitive capacities, although we are reluctant to say that he knows he is in front of a barn. Duncan Pritchard concludes from this that a safety clause, irreducible to the conditions (...) a true belief must satisfy in order to be credited to the believer, constitutes a necessary condition of knowledge. Because those who define knowledge as a cognitive achievement have not convincingly answered this objection, I intend, in the first section of this paper, to refute it by showing how practical and doxastic achievements differ. Then I defend the idea that we should also distinguish two kinds of environmental epistemic luck, and, correlatively, two kinds of safety, that are not equally incompatible with knowledge. Finally, I argue that this distinction is inevitably vague and I indicate some consequences of this vagueness for our knowledge‐intuitions. (shrink)

It is well known that working memory performance changes with age. Two recent computational models of working memory, TBRS* and SOB-CS, developed from young adults WM performances are opposed regarding the postulated causes of forgetting, namely time-based decay and interference for TBRS* and SOB-CS, respectively. In the present study, these models are applied on a set of complex span data produced by young and older adults. As expected, these models are unable to account for the older adult data. An investigation (...) on the effect of the main parameters of these models showed that the poorer performance of older adults does not come from a weaker encoding of item but rather from difficulties during the free time that immediately follows each distractor, as well as from a higher level of confusion between items. These results are discussed with respect to the current theories of working memory and aging. (shrink)
