1. ProlégomènesL’usage de méthodes mathématiques pour traiter de données textuelles a une longue tradition. On se souvient que c’est en étudiant Pouchkine que Markov a élaboré ses chaînes. La linguistique mathématique (qui dépasse de très loin l’analyse des données textuelles) a connu un peu partout un essor important et a fourni des modèles à bon nombre de travaux portant sur le langage (Chomsky, Harris, Montague, …). On connaît aussi, via des mathématiques fort sophistiquées, la profonde in...

Children’s reasoning on food properties and health relationships can contribute to healthier food choices. Food properties can either be positive (“gives strength”) or negative (“gives nausea”). One of the main challenges in public health is to foster children’s dietary variety, which contributes to a normal and healthy development. To face this challenge, it is essential to investigate how children generalize these positive and negative properties to other foods, including familiar and unfamiliar ones. In the present experiment, we hypothesized that children (...) might rely on cues of food processing (e.g., signs of human intervention such as slicing) to convey information about item edibility. Furthermore, capitalizing on previous results showing that food rejections (i.e., food neophobia and picky eating) are a significant source of inter-individual variability to children’s inferences in the food domain, we followed an individual approach. We expected that children would generalize the positive properties to familiar foods and, in contrast, that they would generalize more often the negative properties to unfamiliar foods. However, we expected that children would generalize more positive and less negative properties to unfamiliar sliced foods than to whole unfamiliar foods. Finally, we expected that children displaying higher levels of food rejections would generalize more negative properties than children displaying lower levels of food rejections. One-hundred and twenty-six children, aged 3–6 years, performed an induction task in which they had to generalize positive or negative health-related properties to familiar or unfamiliar foods, whole or sliced. We measured children’s probability of generalization for positive and negative properties. The children’s food rejection score was assessed on a standardized scale. Results indicated that children evaluated positively familiar foods (regardless of processing), whereas they tend to view unfamiliar food negatively. In contrast, children were at chance for processed unfamiliar foods. Furthermore, children displaying higher levels of food rejections were more likely to generalize the negative properties to all kinds of foods than children displaying lower levels of food rejections. These findings entitle us to hypothesize that knowledge-based food education programs should take into account the valence of the properties taught to children, as well as the state of processing of the food presented. Furthermore, one should take children’s interindividual differences into account because they influence how the knowledge gained through these programs may be generalized. (shrink)

The algebraic structure of the 8-spinor formalism is discussed, and the general form of the 8-component wave equation, equivalent to the second-order 4-component one, is presented. This allows a canonical formulation that will be the first stage of the future Clebsch parametrization, i.e., a relativistic generalization of the Bohm-Schiller-Tiomno pioneering work on the Pauli equation.

If such a thing as nanoethics is possible, it can only develop by confronting the great questions of moral philosophy, thus avoiding the pitfalls so common to regional ethics. We identify and analyze some of these pitfalls: the restriction of ethics to prudence understood as rational risk management; the reduction of ethics to cost/benefit analysis; the confusion of technique with technology and of human nature with the human condition. Once these points have been clarified, it is possible to take up (...) some weighty philosophical and metaphysical questions which are not new, but which need to be raised anew with respect to nanotechnologies: the artificialization of nature; the question of limits; the role of religion; the finiteness of the human condition as something with a beginning and an end; the relationship between knowledge and know-how; the foundations of ethics.

Structuralism has recently moved center stage in philosophy of mathematics. One of the issues discussed is the underlying logic of mathematical structuralism. In this paper, I want to look at the dual question, namely the underlying structures of logic. Indeed, from a mathematical structuralist standpoint, it makes perfect sense to try to identify the abstract structures underlying logic. We claim that one answer to this question is provided by categorical logic. In fact, we claim that the latter can be seen—and (...) probably should be seen—as being a structuralist approach to logic and it is from this angle that categorical logic is best understood.

The history of the Nicaraguan Revolution has received considerable analytical attention. Typically, the successful overthrow of the Somoza regime in the late 1970s is associated with the Frente Sandinista de Liberación Nacional, a Marxist/socialist inspired vanguard group. While the role Christians played in the revolution is often acknowledged as a significant one, in part because many Sandinista cadres were Christian revolutionaries, little attention has been paid to the degree to which Sandinismo, as a unique perspective on socialism, shares elective affinities (...) with liberation theology, a prophetic expression of Christianity. This manuscript sets out to explore the relationship between liberation theology and Sandinismo-as-socialism. It starts by considering the perspective of Christian revolutionaries on this relationship. It then identifies the electives affinities between the aforementioned cultural frameworks, and it evaluates the Nicaraguan Revolution in light of these elective affinities. The latter evaluation includes exploring the connection between Saint Paul and what it means to be a Sandinista revolutionary. (shrink)

Résumé Le principe de précaution est une réponse apportée à un vrai problème. Les menaces auxquelles l’humanité se trouve confrontée aujourd’hui, et dont la mise en système pourrait mettre sa survie en danger, requièrent une forme de prudence radicalement nouvelle. Ni la phronêsis des Anciens ni le calcul des chances des Modernes ne conviennent. Le principe de précaution apparaît cependant incapable de relever ce défi, tant ses fondements conceptuels sont faibles et inadéquats. Il se trompe en particulier de cible en (...) posant que c’est l’incertitude qui paralyse l’action. On montre que c’est plutôt l’incapacité où l’on se trouve de transformer ce que l’on sait en croyances incitant à l’action. C’est au niveau d’une métaphysique de la temporalité que l’on cherche une réponse à ce défi, en introduisant des modalités de type bergsonien dans une nouvelle approche de l’argument dominateur. La construction qui en résulte conduit à une forme inédite de rationalité dont on explore les propriétés parfois paradoxales. (shrink)

The article argues the need to rehabilitate the concept of alienation within the post-Fordist model of production, insofar as it is the concept which – if we leave aside the general analysis of wage-labour within capitalist social structures – is best able to explain how the newly devised tools for the management of labour and, most importantly, for the mobilisation of the subjectivities of salaried workers, lead to a reduction both of their autonomy in work and of their opportunities for (...) escape from the stipulated behavioural norms. Finally, it is argued that the procedures for the organisation of production and labour, along with the mechanisms intrinsic to the mobilisation of labour, establish, to an unprecedented degree, the conditions for a denegation of alienation, thus consolidating it.

In this unique study, Jean-Pierre Clero examines medical ethics from a philosophical perspective. Based on the thoughts of great philosophers, he develops a theory of medical ethics that focuses on the values of intimacy.

Jean-Pierre Dupuy a tenu pendant la pandémie un « journal de pensée » d'un genre spécial : il réagit moins aux événements que nous avons tous vécus depuis le mois de mars 2020 qu'à la manière dont ces événements ont été analysés, discutés. Il le fait à la lumière de sa contribution majeure à la pensée de la catastrophe développée dans un livre fameux et souvent mal compris, Pour un catastrophisme éclairé. Quand l'impossible est certain (Seuil, 2002 ; (...) 2004). Voici un livre de combat mû par la colère. La colère de voir des intellectuels relativiser la gravité de la pandémie en cours, s'engager dans une critique virulente de sociétés et de gouvernants qu'ils jugent obsédés par la « protection de la vie », au point de sacrifier l'avenir du monde, de l'économie et des libertés publiques. Avec rigueur et détermination, Jean-Pierre Dupuy leur répond et met au jour les erreurs logiques - et scientifiques - qui sous-tendent ces raisonnements, et propose par là même une réflexion passionnante et passionnée sur la mort et la vie au temps de la pandémie."--Page 4 of cover.

An examination of the fundamental role cybernetics played in the birth of cognitive science and the light this sheds on current controversies. The conceptual history of cognitive science remains for the most part unwritten. In this groundbreaking book, Jean-Pierre Dupuy—one of the principal architects of cognitive science in France—provides an important chapter: the legacy of cybernetics. Contrary to popular belief, Dupuy argues, cybernetics represented not the anthropomorphization of the machine but the mechanization of the human. The founding fathers (...) of cybernetics—some of the greatest minds of the twentieth century, including John von Neumann, Norbert Wiener, Warren McCulloch, and Walter Pitts—intended to construct a materialist and mechanistic science of mental behavior that would make it possible at last to resolve the ancient philosophical problem of mind and matter. The importance of cybernetics to cognitive science, Dupuy argues, lies not in its daring conception of the human mind in terms of the functioning of a machine but in the way the strengths and weaknesses of the cybernetics approach can illuminate controversies that rage today—between cognitivists and connectionists, eliminative materialists and Wittgensteinians, functionalists and anti-reductionists. Dupuy brings to life the intellectual excitement that attended the birth of cognitive science sixty years ago. He separates the promise of cybernetic ideas from the disappointment that followed as cybernetics was rejected and consigned to intellectual oblivion. The mechanization of the mind has reemerged today as an all-encompassing paradigm in the convergence of nanotechnology, biotechnology, information technology, and cognitive science. The tensions, contradictions, paradoxes, and confusions Dupuy discerns in cybernetics offer a cautionary tale for future developments in cognitive science. (shrink)

La démocratie contemporaine, aux yeux des peuples et des cultures d'aujourd'hui, souffre d'une crise de crédibilité. Pour qui croit encore aux principes et idéaux de la démocratie, la compréhension de cette crise est une urgence intellectuelle et pratique de notre temps. L'essai présenté ici est un effort soutenu dans ce sens. Or comprendre cette crise, c'est d'abord comprendre les fondements des principes et des valeurs qui font de la "thèse démocratique" une thèse défendable, sur le registre de la raison critique, (...) mais aussi, et surtout, de l'expérience. Et l'expérience, précisément, nous fournit-elle une image cohérente du fonctionnement démocratique réel de nos sociétés? Dans la sphère économique, les rapports de pouvoir sont-ils aussi démocratiques que dans la sphère politique? D'où la question centrale : la démocratie peut-elle être fondée universellement, à tous les niveaux de l'organisation sociale? (shrink)

Dans l'impossibilite de s'instaurer ex nihilo, toute societe doit definir la nature des rapports que ses valeurs, ses normes, ses institutions et ses moeurs actuelles entretiennent avec celles qui gouvernaient son passe. Ces rapports se situent entre deux poles: celui de la reconduction et de la reproduction les plus fideles d'une part; celui de la rupture et de l'arrachement d'autre part. Les societes voisines du premier pole seront qualifiees de traditionnelles; celles plus proches du second seront appelees modernes. On reservera (...) le qualificatif de traditionalistes aux societes ou sous-groupes sociaux qui, au sein du monde moderne, veulent ouvertement, sinon restaurer, du moins rester inconditionnellement fideles a des principes, regles et modes de vie subvertis par la dynamique de la modernite. Apres avoir examine la polysemie de la tradition et du rapport a la tradition, l'ouvrage etudie en detail trois cas particuliers de la dialectique entre tradition et modernite la secularisation du christianisme et les mutations contemporaines des croyances et pratiques religieuses; la tension entre contractualisme et traditionalisme dans la constitution et les manifestations de l'appartenance nationale republicaine; la tradition du nouveau dans les arts plastiques.

This paper aims to connect philosophy of chemistry, green chemistry, and moral philosophy. We first characterize chemistry by underlining how chemists: co-define chemical bodies, operations, and transformations; always refer to active and context-sensitive bodies to explain the reactions under study; and develop strategies that require and intertwine with a molecular whole, its parts, and the surroundings at the same time within an explanation. We will then point out how green chemists are transforming their current activities in order to act upon (...) the world without jeopardizing life. This part will allow us to highlight that green chemistry follows the three aforementioned characteristics while including the world as a partner, as well as biodegradability and sustainability concerns, into chemical practices. In the third part of this paper, we will show how moral philosophy can help green chemists: identify the consequentialist assumptions that ground their reasoning; and widen the scope of their ethical considerations by integrating the notion of care and that of vulnerability into their arguments. In the fourth part of the paper, we will emphasize how, in return, this investigation could help philosophers querying consequentialism as soon as the consequences of chemical activities over the world are taken into account. Furthermore, we will point out how the philosophy of chemistry provides philosophers with new arguments concerning the key debate about the ‘intrinsic value’ of life, ecosystems and the Earth, in environmental ethics. To conclude, we will highlight how mesology, that is to say the study of ‘milieux’, and the concept of ‘ecumeme’ proposed by the philosopher and geographer Augustin Berque, could become important both for green chemists and moral philosophers in order to investigate our relationships with the Earth.

L’édition critique des œuvres de Moïse ben Sabbataï, philosophe juif actif (à Rome?) vers 1340, avait signalé, parmi d’autres sources latines lues dans les traductions en hébreu de son contemporain Juda de Rome, un exemplum présentant le sage athénien Solon sur son lit de mort en champion de la doctrine de l’élévation intellectuelle en vue de la vie éternelle. Cette note identifie comme sa source un chapitre d’Albert le Grand, De natura et origine animae II, 13, dont la traduction en (...) hébreu se trouve dans un ouvrage inédit de Juda de Rome, son Commentaire du Qaddīš et de la Qeduššāh. La traduction du chapitre est éditée, l’histoire de l’ exemplum reconstituée et son emploi par les trois auteurs, remis en contexte et interprété. (shrink)

This paper first queries what type of concept of emergence, if any, could be connected with the different chemical activities subsumed under the label ‘quantum chemistry’. In line with Roald Hoffmann, we propose a ‘rotation to research laboratory’ in order to point out how practitioners hold a molecular whole, its parts, and the surroundings together within their various methods when exploring chemical transformation. We then identify some requisite contents that a concept of emergence must incorporate in order to be coherent (...) from the standpoint of the scientific practices involved. In this respect, we finally propose a relational form of emergence which pays attention to the constitutive role of the modes of intervention and to the co-definition of the levels of organization. No metaphysical distinction between the higher and basic levels of organization is supposed, but only a plurality of modes of access. Moreover, these modes of access are not construed as mere ways of revealing intrinsic patterns of organization but, on the contrary, are considered to be active elements on which the constitution of those patterns depends. What is at stake in this paper is therefore not an ontological form of emergence but an agnostic one which fits what chemists do in their daily work. (shrink)

Suppose we were to meet with extraterrestrials and that we were able to have a discussion about our respective cultures. At some point, they start asking questions about that something which we call “mathematics”. “What is it?”, they ask. Tough question. How should we answer them?

Au XVIIème siècle, c’est la découverte du principe d’inertie, un concept purement physique, qui permit de débloquer la théorisation du mouvement, en panne depuis Aristote. La plupart des philosophes et historiens des sciences caractérisent le tournant de la « science moderne » par sa mathématisation, arguant, comme Koyré, que le principe d’inertie découlerait de cette dernière, ou bien, comme Duhem, qu’il était déjà contenu dans l’impetus médiéval, ou encore, comme, Husserl et Kojève, en s’abstenant d’en parler. Et pourtant, la mathématisation (...) de la physique était en marche depuis l’époque hellénistique. L’originalité de Galilée est d’avoir mathématisé non pas la nature, mais, via le principe d’inertie, le temps. (shrink)

Introduced and commented by specialists in film studies and philosophy, Meunier's intricate phenomenological descriptions of the spectator's engagement with fiction films, documentaries and home movies can reach the wide audience they have deserved ever since their publication in French in 1969.

Cet article traite des analyses proposées par Karl Marx et par Friedrich Engels sur le mouvement des salaires dans la dynamique du capitalisme, et sur la question de la « paupérisation » des travailleurs, en particulier entre les années 1840 et les années 1860. Il montre que si Engels n’a jamais pronostiqué clairement une « paupérisation absolue » ou « relative », Marx, dans ses écrits des années 1860 et au-delà, maintient la thèse d’une baisse du « salaire relatif », (...) mais ne pronostique plus une baisse des salaires réels en longue période, et ne formule aucune « loi » de « misère croissante » du prolétariat.

For Suarès, Baudelaire was the first poet to take himself as an object of reflection : as an innovator in introspection, he was inevitably pessimistic. Bringing in light his history of misfortune and his guilt, Suarès sees him as a theologian, among other things, especially in his assertion : "What is natural is vile". Since nature is corrupt, art is purification. If Baudelaire is religious, it is in a strange way indeed. Nevertheless, one finds in him the presence of a (...) religious idea of "redemption", to which the poet aspires with all his might. "The flowers are not all 'of evil', as one might imagine. Sin insinuates its singular virtue there, prompting great remorse in the sinner and then leading him towards redemption". Starting from Suarès, as well as the reflections of Benjamin Fondane and Yves Bonnefoy, J.-P. Jossua attempts in these pages to understand what Baudelaire's religion was. (shrink)
