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)

, 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)

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.

Aristote soutenant que les plaisirs corporels se sont accaparés le nom de plaisir, il sous-entend clairement par là que ce ne sont pas les seuls. On aurait tort, cependant, malgré la tradition médiévale, de ne voir dans les plaisirs non-corporels que les plaisirs dus à la « vie contemplative » menée par le sage d’Aristote. Il existe des « plaisirs intellectuels » et ils ne sont pas nécessairement « spirituels ». C’est par exemple le cas du géomètre exerçant la géométrie (...) et c’est à l’analyse de ces plaisirs qu’est consacrée cette étude. (shrink)

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)

When it was first published in French in 1980, The Ordinary Man of Cinema signaled a shift from the French film criticism of the 1960s to a new breed of film philosophy that disregarded the semiotics and post-structuralism of the preceding decades. Schefer describes the schizophrenic subjectivity the cinema offers us: the film as a work projected without memory, viewed by (and thereby lived by) a subject scarred and shaped by memory. The Ordinary Man of Cinema delineates the phenomenology of (...) movie-going and the fleeting, impalpable zone in which an individuals personal memory confronts the cinemas ideological images to create a new way of thinking. It is also a book replete with mummies and vampires, tyrants and prostitutes, murderers and freaksfigures that are fundamental to Schefers conception of the cinema, because the worlds that cinema traverses (our worlds, interior and exterior) are worlds of pain, unconscious desire, decay, repressed violence, and the endless mystery of the body. Fear and pleasure breed monsters, and such are what Schefers emblematic "ordinary man" seeks and encounters when engaging in the disordering of the ordinary that the movie theater offers him. Among other things, Schefer considers "The Gods" in 31 brief essays on film stills and "The Criminal Life" with reflections on spectatorship and autobiography. While Schefers book has long been standard reading in French film scholarship, until now it has been something of a missing link to the field (and more broadly, French theory) in English. It is one of the building blocks of more widely known and read translations of Gilles Deleuze (who cited this book as an influence on his own cinema books) and Jacques Rancière. (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)

Inλ-calculus, the strategy of leftmost reduction (“call-by-name”) is known to have good mathematical properties; in particular, it always terminates when applied to a normalizable term. On the other hand, with this strategy, the argument of a function is re-evaluated at each time it is used.To avoid this drawback, we define the notion of “storage operator”, for each data type. IfT is a storage operator for integers, for example, let us replace the evaluation, by leftmost reduction, ofϕτ (whereτ is an integer, (...) andϕ anyλ-term) by the evaluation oftτϕ. Then, this computation is the same as the following: first computeτ up to some reduced formτ 0, and then applyϕ toτ 0. So, we have simulated “call-by-value” evaluation within the strategy of leftmost reduction.The main theorem of the paper (Corollary of Theorem 4.1) shows that, in a second orderλ-calculus, using Gödel's translation of classical intuitionistic logic, we can find a very simple type (or specification) for storage operators. Thus, it gives a way to get such operators, which is to prove this type in second order intuitionistic predicate calculus. (shrink)

Au Chant Premier du Paradis, Dante fait de la poésie un art de la subversion sinon de la transgression, en lui assignant la tâche de travailler la parole pour en contourner les limites : Outrepasser l’humain, c’est aller au-delà des limites du langage, prétendre aux formes angéliques de la communication. Les anges font une expérience heureuse de l’indicible et se comprennent en silence. C’est dans cet intervalle que la poésie doit se frayer son chemin et faire accéder l’impensable à l’expression, (...) dire l’indicible. Elle doit signifier par des mots (« significar per verba ») ce qui excède toute signification humaine. Nous retrouvons ici la théologie négative et son inventeur Denys l’Aréopagite : quand la théologie, confrontée à l’ineffable, aboutit au silence et à l’apophatisme, la poésie répond à l’appel pour assurer le passage de l’invisible à la figuration. Figuration également négative, qui fait exploser des images « bigarrées », faites de mots pour ainsi dire illisibles. En quoi la poésie a vocation à devenir non figurative. (shrink)

Comment et pourquoi affirmer que l'humanisme d'un penseur catholique du XVIIe siècle peut nous guider dans la compréhension de phénomènes culturels contemporains, c'est in fine la question qui commande cette étude rigoureuse et audacieuse. Faire dialoguer de façon féconde le projet de Blaise Pascal et la pop culture, appréhendée à partir des tribus musicales punk, rock, skinhead, gothique, hip-hop et électro, c'est l'objectif du travail de Jean-Louis Bischoff.

Many logicians have tried to formalize a modal logic from the Prior Analytics, but the general view is that Aristotle has failed to offer a consistent modal logic there. This paper explains that Aristotle is not interested in modal logic as such. Modalities for him pertain to the relations of predication, without challenging the assertoric system of deductions simpliciter. Thus, demonstrations or dialectical deductions have modal predicates and yet are still deductions simpliciter. It is a matter of distinguishing inferential necessity (...) that applies to every deduction from the modal predicates in the two premises and conclusion. The modality of demonstrations can be either necessary or possible. The necessity is predicative, i.e., independent of inferential necessity. While the possible demonstration challenges the predicative necessity of the necessary demonstration, it preserves the inferential necessity of the deduction simpliciter. (shrink)

Plutôt que de prendre le parti d’une critique – par ailleurs légitime – des usages, notamment managériaux, de la compétence éthique, ce texte propose de prendre le concept au sérieux et de tenter de l’éclairer en s’appuyant notamment sur les approches pragmatistes des émotions développées par James, Dewey et Peirce. Plutôt que de privilégier une accentuation délibérative et argumentative des compétences éthiques favorisée par l’efflorescence et la multiplication des « comités d’éthique », il cherche principalement à penser les émotions comme (...) compétences éthiques, tout en en revendiquant une conception cognitiviste. Les « compétences éthiques » sont tout d’abord déployées sous les accentuations possibles de la responsabilité, distinguées selon la grammaire des pronoms personnels, comme autonomie, comme sollicitude, comme souci du collectif, comme accusation... L’éclairage pragmatiste des émotions comme compétences éthiques permet ensuite d’ouvrir à une approche renouvelée de l’« engagement » pensé comme compétence, couvrant un large spectre allant des engagements volontaires, obéissant à des décisions, jusqu’à des engagements à dominante émotionnelle caractéristiques par exemple des « communautés esthétiques », du ressentir, du vibrer ensemble.

L’une des conséquences indirectes de la rupture de l’unité confessionnelle aux temps modernes, fut une exploration accélérée du passé chrétien. Pour cela, une masse régulièrement accrue de documents venait nourrir deux représentations antagonistes de l’histoire de l’Eglise, lesquelles étaient défendues par des travaux d’érudition au service de deux conceptions de l’histoire, qui étaient aussi bien deux théologies de l’Eglise. Cependant, l’exigence de proximité des sources devait induire un mode particulier d’écriture de l’histoire qui transcenderait les frontières confessionnelles, tout en maintenant (...) des positions différentes. La prise en compte des documents allait notamment renforcer une certaine critique, pour laquelle surgissent notamment les noms de Mabillon et de Le Nain de Tillemont, même si les positions continueraient de se différencier tout au long du XVIIe siècle.One of the indirect consequences of the break up of confessional unity in modern times was an accelerated exploration of the Christian past. In the process, a constantly increasing mass of documents came to fuel two opposing representations of the history of the Church. These representations were supported by works of erudition in keeping with two different conceptions of history, which were also two theologies of the Church. The use of new sources became required, however, and led it to a particular way of writing history that would transcend confessional boundaries, while maintaining different positions. Taking these documents into account strengthened a critical current that gave rise to Mabillon and Le Nain de Tillemont, even though the positions continued to differ throughout 17th century.

A great deal of thought has been given to the effects of information technology on reading, books and printed material. Its impact on writing, the production of texts, which is, however, the counterpart of reading, has not aroused the same interest. It is true that witnesses to the act of creation are less familiar objects than books or newspapers: in spite of the passion of the media and the educated public for writers’ manuscripts, these remain predominantly the prerogative of researchers (...) and are still rarely taken out of libraries and archive collections. In extremely literate Western societies, reading is an activity practised by large sectors of the population. The same cannot be said about writing as an active producer of texts, for this encompasses a much more limited group of professionals, and is thought, more or less, to require a special gift in its literary form. Written production is rather the hidden face of McLuhan's Gutenberg galaxy, and the commercial businesses which manufacture and distribute writing in its printed form are better known to the public than the mysterious secrets of creation.

Un foisonnement d'expériences associatives et coopératives s'est manifesté dans les différents pays européens depuis les années 1970, particulièrement dans le champ des initiatives locales et des nouveaux services relationnels. Selon la grille d'analyse adoptée qui privilégie le potentiel de démocratisation, ces pratiques peuvent être mieux comprises à travers une perspective d'économie solidaire que par les références habituelles au tiers secteur, à l'économie sociale et aux organisations non gouvernementales. Néanmoins, comme l'interdépendance entre actions collectives et publiques s'avère déterminante dans l'histoire européenne (...) pour organiser une résistance à l'utopie d'une « société de marché », le devenir de l'économie solidaire est étroitement lié à la reconnaissance par les pouvoirs publics. Tant au niveau national qu'international celle-ci reste partielle et la pertinence d'un soutien ne fait pas consensus comme le montre la position de l'Union européenne.A large amount of associative and cooperative experiments has arisen everywhere in Europe since the 1970s particularly in the fields of local initiatives and new “relational” services. Our framework of analysis shows these practices are better understood by a civil and solidarity-based economy perspective, emphasizing their potential of economic democratization, rather than by the usual references to third sector, social economy or non-governmental organizations. Nevertheless, since collective and public action has interacted decisively in European history to organize resistance against the utopic vision of the “market society”, the future of this solidarity-based economy appears to be closely linked to its recognition by public policies. But at the European and national levels, this still remains partial and the relevance of such an economy is a highly controversial subject as the European Union’s position demonstrates. (shrink)

Há anos ou décadas, vemos países que estavam em marcha em direção à democracia como a Rússia, a Turquia e mesmo reais democracias como o Brasil, se tornarem verdadeiras democraduras, ou se encaminharem para esse tipo de regime, a Hungria por exemplo, mas igualmente outros países. Os analistas políticos continuam lutando para entender a origem e a natureza desse direcionamento sobre o qual a leitura de Tocqueville ainda fornece um esclarecimento notável, cujas análises mantêm perfeita atualidade; é um grande pensador (...) para os dias atuais que estabelece como, para pensar o surgimento da democracia e os problemas que aparecem a ela, é apropriado partir do estado social democrático.

Two strains of male mice have bred over fortygenerations, starting with the work of RobertCairns and his colleagues, one strain with ahigh level of intra-species aggression, theother a low level of aggression. Thehigh-aggression mice tend to establishdominance hierarchies and particularly fight inthe presence of female mice. Thelow-aggression mice tend, in groups of theirown, to have a high degree of low-intensity,peaceful social contact, and to be more timidin initiating action than the high-aggressionmice. Biochemical differences have beenobserved between the two strains, and (...) confirmedby the present data: the high-aggression micehave greater dopamine concentrations (in thecaudate nucleus and nucleus accumbens), lowerlevels of the stress hormone corticosterone,and higher levels of testosterone than thelow-aggression mice. The current experimentswere designed to answer questions about theflexibility of adaptive behaviors:specifically, what is the effect of early dailymaternal separation on adult stress response ineach strain? What are the behavioral andhormonal mechanisms by which, as has beenobserved, low-aggression mice achieve adominant status when brought into situationswhere they compete for territory withhigh-aggression mice? Finally, what are thesocial and neurochemical mechanisms by whichhigh-aggression mice can develop low-aggressionbehavior if brought out of isolation and intogroups?Maternal separation was found to lead todecreases in stress levels, as measured bycorticosterone, in the low-aggression but notthe high-aggression, mice – presumably becauseof the surplus of maternal care the pupsreceive on returning to the nest. When alow-aggression mouse became dominant and ahigh-aggression mouse became submissive, theirusual pattern of corticosterone andtestosterone levels was found to be reversed. The change to low-aggression behavior inhigh-aggression mice switching from anisolation condition to a group condition, wasmediated by a decrease in D 1 dopaminereceptor densities.These results, like the ones on which theybuild, argue for substantial developmentalinfluences in expressions of the genesinfluencing aggressive or cooperative behavior. In this approach to evolution, epigenesis istreated not as a set of traits and behaviorspredetermined by the genome, but as a set ofprobabilistic tendencies toward certain traitsand behaviors.

. The aim of this paper is to clarify the logical structure of a code connecting together some distinctions already introduced by different authors: a distinction between primary norms and secondary norms, the latter being implied by the provisions describing institutions in the indicative; a distinction between norms the content of which concerns a state and those the content of which concerns a behaviour which is itself function of several states; a distinction, among the primary norms, of the norms of (...) competence by which a normative power can be delegated to an individual; lastly a distinction between regulative rules and constitutive rules.
