This article deals with the methodologies commonly used in the framework of the structural approach to social representations. It concerns free and hierarchical evocations, the characterization questionnaire, the similarity analysis, the basic cognitive schemes model, the attribute-challenge technique and the test of context independence. More than a simple review of these methodologies, it offers a critical approach concerning the problems encountered and related to: thresholds or “cutoff points” used to diagnose the structure and the accuracy of the structural diagnosis, grouping (...) methods employed to reduce the corpus of verbal associations, the dilemma between reliability and feasibility, especially in field research, the adequacy and number of modalities of response in the framework of the structural diagnosis. Following this evaluation, this article suggests potential solutions to overcome these methodological limitations. Moreover, as methodological issues are closely related to theoretical questions, the link between social representation theory and identity approaches is discussed. (shrink)

New concepts may prove necessary to profit from the avalanche of sequence data on the genome, transcriptome, proteome and interactome and to relate this information to cell physiology. Here, we focus on the concept of large activity-based structures, or hyperstructures, in which a variety of types of molecules are brought together to perform a function. We review the evidence for the existence of hyperstructures responsible for the initiation of DNA replication, the sequestration of newly replicated origins of replication, cell division (...) and for metabolism. The processes responsible for hyperstructure formation include changes in enzyme affinities due to metabolite-induction, lipid-protein affinities, elevated local concentrations of proteins and their binding sites on DNA and RNA, and transertion. Experimental techniques exist that can be used to study hyperstructures and we review some of the ones less familiar to biologists. Finally, we speculate on how a variety of in silico approaches involving cellular automata and multi-agent systems could be combined to develop new concepts in the form of an Integrated cell (I-cell) which would undergo selection for growth and survival in a world of artificial microbiology.

Discarding the traditional image of the Enlightenment as the (...) absolute enemy of absolutism, Gordon, in this sense, follows Norbert Elias and Robert Darnton who treat the Enlightenment as part of an elitist and hierarchical establishment. More specifically, as his subtitle indicates, Gordon portrays the invention of a “nonpolitical polis” (p. 6), an ideological social space where, despite political inequality, citizens could practice social equality in a hierarchical régime. The rise of this “nondemocratic egalitarian ethos” (p. 7) brought with it a new cult of sociabilité, a term invented in the eighteenth century to describe the idealization of the private sphere and the practice of social equality.The first chapter, then, ties sociability not to democracy, as in the Habermasian model, but to the absolutism that stimulated it and coexisted with it. A series of five ideal types of sociability depict how men and women, members of the bourgeoisie and the aristocracy, came together—in commerce, public welfare, scientific academies, salons, cafés, public libraries, and various other social situations not protorevolutionary in character—to create a bond among equals [End Page 279] under the ancien régime. In this framework, progress and modernity are born during the absolute monarchy where sociability suggests conviviality rather than class warfare. Every major French novel of the eighteenth century supports Gordon’s refutation of De Toqueville’s surprising statement that “noblemen and bourgeois never met except by chance in private life “in prerevolutionary France” (p. 27).In chapters two and three, Gordon examines the nature of the rules of sociability found in courtesy literature and their functioning as the imagined basis of the newly invented idealized space called société. In addition to analyzing in great detail the nature and frequency of the vocabulary invented to define and describe sociabilité, Gordon discusses sociabilité in the context of natural law theory in Hobbes, Bossuet, and among others, Pufendorf, who wanted to refute Hobbes by showing that self-interest leads humans to establish stable social relations even before government orders them to do so. Holbach surfaces here too for having amalgamated the older language of politeness and the newer language of natural law. In Holbach, as in the Encyclopédie, sociability, based on egalitarian premises of natural law, is nonetheless fully compatible with the hierarchical regime. Among other things, this shows clearly that the philosophes never preached the French Revolution. Striving to eliminate the abuses of despotism and establish equality in private life was not tantamount to working for political equality and the abolition of all rank. In this same vein, Gordon paints the apolitical essence of the private sphere and, by a rigorous study of the seventeenth-century manuals of polite living, shows convincingly (this time against Elias who saw the court as a model of refined behavior) that the salon was indeed a world unto itself, independent of preexisting social hierarchies. Rejecting Paul Hazard’s conception of absolute rupture between seventeenth-century culture and eighteenth-century thought, Gordon destroys the facile dichotomy between seventeenth-century hierarchy and eighteenth-century equality and, once again, admirably depicts the compatibility of Enlightenment and absolutism.If chapters one to three underscore a certain continuity between the seventeenth and eighteenth centuries, chapters four and five explain important changes. It is not, for example, the mere preservation of the idea of sociable communication but rather its new use that is germane in understanding the Enlightenment. Now “conversation” and “civility” no longer had meaning only for an urban elite but had in fact become ideals in all philosophical endeavors including the writing of universal history. Sociable communication had become the defining characteristic of modern nations. In the fourth chapter, by analyzing in detail the works of Jean-Baptiste Suard, Gordon demonstrates the meaning that the writing of universal history in Scotland acquired within the French...

, which uses the intuitionistic propositional calculus, with the only connective →. It is very important, because the well known Curry-Howard correspondence between proofs and programs was originally discovered with it, and because it enjoys the normalization property: every typed term is strongly normalizable. It was extended to second order intuitionistic logic, in 1970, by J.-Y. Girard [4], under the name of system F, still with the normalization property.More recently, in 1990, the Curry-Howard correspondence was extended to classical logic, following (...) Felleisen and Griffin [6] who discovered that the law of Peirce corresponds to control instructions in functional programming languages. It is interesting to notice that, as early as 1972, Clint and Hoare [1] had made an analogous remark for the law of excluded middle and controlled jump instructions in imperative languages.There are now many type systems which are based on classical logic; among the best known are the system LC of J.-Y. Girard [5] and the λμ-calculus of M. Parigot [11]. We shall use below a system closely related to the latter, called the λ c -calculus [8, 9]. Both systems use classical second order logic and have the normalization property.In the sequel, we shall extend the λ c -calculus to the Zermelo-Frænkel set theory. The main problem is due to the axiom of extensionality. To overcome this difficulty, we first give the axioms of ZF in a suitable (equivalent) form, which we call ZF ɛ. (shrink)

This paper shows that Aristotle's De Interpretatione does not separate syntax from semantics. Linguistic sentences are not syntactic entities, and non-linguistic meanings are not semantic propositions expressed by linguistic sentences. In fact, Aristotle resorts to a mental conception of meaning, distinguishing linguistic meanings in a given language from non-linguistic mental contents in relation to actual things: while the former are not the same for all, the latter are shared by everyone. Aristotle is not a modern logician, like Boole, Frege, or (...) Russell, in so far as a mental conception of meaning does not reveal an abstract semantics for a syntactic language. (shrink)

In this article first appeared in 1997, Jean-Louis Chrétien examines the meaning of prayer in Kierkegaard’s writings and existence. By focusing on the difficulties of this task and with meticulous attention to the vast work of the Danish philosopher, Chrétien describes prayer as a tense and agonistic experience, akin to the evangelical struggle between Jacob and the angel. Just like in his well-known phenomenological analysis, “The Wounded Word: Phenomenology of Prayer”, the author identifies in prayer a paradoxical articulation (...) of struggle and peace, gift and endeavour, speaking and listening, through which the human being is profoundly transformed and finally learns to truly say “thank you”.

Introduction. Il est bien connu que la correspondance de Curry-Howard permet d'associer un programme, sous la forme d'un λ-terme, à toute preuve intuitionniste, formalisée dans le calcul des prédicats du second ordre. Cette correspondance a été étendue, assez récemment, à la logique classique moyennant une extension convenable du λ-calcul. Chaque théorème formalisé en logique du second ordre correspond donc à une spécification de programme.Il se pose alors le problème, en général tout à fait non trivial, de trouver la spécification associée (...) à un théorème donné; autrement dit, de déterminer le comportement opérationnel commun aux λ-termes associés aux diverses démonstrations formelles du théorème considéré.Cette question est résolue ici pour le théorème de complétude de la logique classique.La première étape consiste à formaliser convenablement ce théorème en logique du second ordre. Ce travail est fait complètement dans la section 1. Il a comme sous-produit, peut-être inattendu, de montrer que ce théorème est prouvable en logique intuitionniste du second ordre. Ceci, toutefois, à condition d'introduire une légère variante de la notion de modèle, en admettant un modèle supplémentaire trivial, où toute formule est satisfaite.On notera, à ce sujet, que des preuves intuitionnistes du théorème de complétude de la logique intuitionniste, utilisant des variantes de la notion de modele de Kripke, ont été données par H. Friedman [7] et W. Veldman [8]. On remarquera également qu'un argument de G. Kreisel [2] montre que le théorème de complétude habituel de la logique intuitionniste n'a pas de preuve intuitionniste.

Véronique Adam : Les neurosciences ne s’intéressent que depuis très récemment à l’olfaction. Pourriez‑vous expliquer pourquoi ce sens est devenu un objet d’étude plus prégnant? Jean-Louis Millot : En fait, l’olfaction demeure encore peu étudiée comparée à d’autres modalités sensorielles. De manière générale, les neurosciences cognitives actuelles, comme d’autres investigations scientifiques chez l’homme par le passé, se focalisent davantage sur les compétences cognitives complexes, telles qu...

La formule selon laquelle « l’homme est un animal politique par nature » est une des plus connues d’Aristote, pour cela même méconnue. L’objet de cette étude est de montrer qu’il n’y a pas lieu d’interpréter cela d’une façon trop naturaliste, ou, pire, « réductionniste ». Que la nature soit à l’origine de l’élan ayant présidé à l’apparition de la polis est certain, mais qu’elle gouverne tout le processus l’est nettement moins. À commencer par les critères de la distinction entre (...) les différentes constitutions, faites par les citoyens eux-mêmes. De même en va-t-il pour l’acquisition de la vertu morale, qui n’est nullement donnée par la nature et que les citoyens se devraient de posséder. D’où il résulte qu’en matière de politique, il est bien plus question d’éducation que de nature. (shrink)

Lo studio degli interventi politici repubblicani fiorentini dopo il 1494 (prediche savonaroliane, testi d'intervento, discorsi, dialoghi, cronache e storie) mette in rilievo in quest'articolo la nascita di una nuova lingua della politica, più immediata, più efficace, più precisa, più chiara che intende render conto dei tempi nuovi della guerra permanente e del suo stato d'emergenza. Questa retorica inedita porta quindi in sé nuove forme di razionalità politica che portono con sé buona parte dell'aurora della politica moderna.

The biological function of human reasoning abilities cannot be to improve shared knowledge. This is at best a side effect. A more plausible function of argumentation, and thus of reasoning, is to advertise one's ability to detect lies and errors. Such selfish behavior is closer to what we should expect from a naturally selected competence.

Signifiance du monde propose une "harmonisation intégrale" entre la linguistique saussuro-guillaumienne des langues naturelles et la pensée phénoménologique heideggérienne de la vérité de l'être en tant qu'alètheia, dans son sens grec de "ce qui sort de la latence" et que Jean-Louis Tristani nomme illatence. En d'autres termes, cet essai donne accès à une compréhension des "relations grammaticales évidentes qui articulent l'être, dans sa vérité, et la pensée, telles qu'elles sont a priori données dans le système linguistique de n'importe (...) quelle langue naturelle". Cette mise au jour de la co-originarité de la langue et de la pensée corrobore la formule du linguiste français Antoine Meillet, maintes fois citée par Gustave Guillaume, selon laquelle, en ce lieu intelligible de la langue "tout se tient et a un plan d'une pleine rigueur". Une rigueur qui intègre le système morpho-lexical d'une langue, en tant qu'intégrale des conditions d'effection du discours, avec les conditions existentiales de possibilité du Dasein en tant qu'être-au-monde. D'où Signifiance du monde, ce titre qui annonce la composante linguistique de notre présence au monde."--Page 4 of cover. (shrink)

Il y a bien eu, dans le refus d'un culte des images en Europe latine, la construction d'un dogme des images portant prescription de leur usage conforme à leur pouvoir d'évocation du passé (un art de mémoire), aux manipulations de figures dans la machinerie des rêves. La théologie et les philosophies en ont fait l'instrument approché de toute connaissance conçue comme la lecture d'un tableau, possible parce que nous en participons par notre nature. Que signifient les formules de la création (...) : l'homme a été fait comme une image? l'homme a été créé selon le mode des images? Dieu a créé l'homme à son image, ou encore, il l'a fabriqué par une image? (shrink)

La défense canguilhemienne de l’institution philosophique s’inscrit dans une lignée républicaine ; cette attitude diffère de celle propre à certains de ses contemporains (Nizan), ou de ses cadets (Althusser, Foucault). Canguilhem a toujours défendu l’importance de la philosophie quand elle était menacée par les sciences humaines et sociales, tant au moment du succès de l’existentialisme que pendant le structuralisme des années 1960 ; il fut, en même temps, le critique de certaines manières de concevoir la philosophie (existentialiste ou spiritualiste), de (...) certaines modes de sa pratique (journalistique ou littéraire), et un innovateur en matière de pédagogie.

Celem pracy jest podanie reguł semantycznych dla logik, w których funkcjonują obok siebie funktory modalne i funktory deontyczne. Idea wspólnego traktowania tych funktorów. a w szczególności badania związków między nimi, została zapoczątkowana jeszcze w 1671 r. przez Leibnitza w "Elementa juris naturalis". Autor rozróżnia trzy następujące koncepcje dotyczące wzajemnych relacji między rozważanymi dwoma rodzajami funktorów logicznych: 1) koncepcję Leibnitza, wg. której konieczność implikuje obowiązek; 2) koncepcję, w której konieczność jest nieporównywalna z obowiązkiem; 3) zmodyfikowaną koncepcję [2] drogą pomysłowej modyfikacji znanej (...) semantyki Kripkego - autor wprowadza dodatkowe rozróżnienie światów na pozytywne i negatywne. Interesująco wypadają też porównania reguł semantyk dla trzech wymienionych wyżej koncepcji i rozważania wzajemnych powiązań czterech pojęć deontycznych: silnego obowiązku, silnego zakazu, słabego przyzwolenia i słabej "dowolności" - okazuje się, że spośród szesnastu możliwych relacji aż osiem spełnionych jest równocześnie we wszystkich trzech semantykach, Artykuł kończą uwagi na temat możliwych konsekwencji i zastosowań zaprezentowanego materiału.
