Résumé Au sein d’une théologie considérée comme fondamentalement pratique, la théologie pratique comme sous-discipline se distingue par un intérêt particulier — empirique, herméneutique, critique et stratégique — pour les pratiques dont elle fait souvent son objet propre. Après avoir signalé quelques impacts de ce centrement sur la pratique, l’article présente quelques définitions de la pratique et quelques éléments d’histoire du concept. Il expose ensuite quelques traits des pratiques, en particulier avec Paul Ricoeur et Jürgen Habermas, conjuguant des perspectives sémantique, pragmatique (...) et communicationnelle. Il vise particulièrement à faire ressortir la richesse et la complexité de la pratique dont l’étude est trop souvent prise comme allant de soi et qui surprennent toujours celui qui s’y adonne.At the heart of a theology which is fundamentally considered to be practical, practical theology, as a sub-discipline, distinguishes itself by its particular empirical, hermeneutic, critical, and strategic interest in the practices with which it is concerned. After pointing out some of the impacts of this central concern with practice, the present article presents some definitions of practice as well as some historical background of the concept. It then examines some of the characteristics of practice, particularly in relation to Paul Ricoeur and Jürgen Habermas, while discussing semantic, pragmatic, and communicational perspectives. In particular, this article aims at highlighting the richness and complexity of practice. (shrink)

Résumé Dans cet article, nous discuterons de l’intégration du numérique à la sémiotique et proposerons qu’une modélisation conceptuelle puisse offrir un pont de dialogue entre ces deux domaines classiquement cloisonnés. Plus précisément, nous avancerons l’hypothèse que tout projet de recherche qui en appellera à l’informatique soit une démarche scientifique que s’il construit une théorie qui contient, en plus des modèles classiques que sont les modèles formel, computationnel et physique, un modèle conceptuel. Ce lieu, où les chercheur-es conceptualisent les multiples dimensions (...) de leur objet de recherche, sera alors défini en tant que socle d’une relation solide entre la sémiotique et l’informatique. Nous verrons que les différentes définitions du modèle conceptuel convergent vers la thèse soutenant que la connaissance scientifique met en œuvre une instance de conceptualisation qui doit identifier les diverses dimensions du problème en plus de devoir s’exprimer de manière à ce qu’elle soit communicable entre les membres des communautés épistémiques. Nous verrons, enfin, qu’un projet de recherché sémiotique exige la construction d’un tel modèle afin de décrire, généraliser et sélectionner des problèmes et que ce même modèle, conceptuel, sera aussi nécessaire si le ou la sémioticien-ne utilise l’informatique dans le cadre de sa recherche.fr.

Cet article propose un lien entre le discours féministe et la perversion. Dans un monde où le sujet pervers est Maître, le réel est anticipé de façon à satisfaire les besoins primaires. Mais la réalité est tout autre, lorsqu'une femme se pose, ou s'oppose, d'une façon plus spontanée, et vient compromettre la quête du pervers : d'objet, dans un monde qui l'assujettit, elle devient sujet. Elle secoue ainsi l'édifice masculin, non sans heurt, car une certaine forme de violence s'impose alors (...) que l'objet résiste. Ce scénario ne fait que rendre manifeste ce que nous savions déjà sur l'agressivité inhérente au rapport pervers. Ce qui a néanmoins comme conséquence d'offrir une autre possibilité de discours qui, d'un point de vue éthique, s'impose à nos sociétés occidentales pour sortir de la perversion et du Même.This paper proposes an explanation for the resistance to feminist discourse, by linking it to perversion. In a world in which the perverse subject dominates, reality is apprehended with the sole satisfaction of primary needs in view. Now such a "reality" becomes wholly transformed so soon as a woman spontaneously asserts or oppose herself, for she appears to compromise the perverse subject's quest; hitherto an object in a subjugating world, she becomes a subject herself. She thus rocks the masculine structure, with resulting clashes, since some degree of violence is inevitable in the face of resistance. This scenario merely manifests what was already known about agression as endemic to perverse relations. From an ethical point of view, however, new possibilities are thus opened up by a discourse which ought to help our Western societies to escape from perversion and Sameness. (shrink)

Argumentation has been an important topic in knowledge representation, reasoning and multi-agent systems during the last twenty years. In this paper, we propose a new abstract framework where arguments are associated with a strength, namely a quantitative information which is used to determine whether an attack between arguments succeeds or not. Our Strength-based Argumentation Framework combines ideas of Preference-based and Weighted Argumentation Frameworks in an original way, which permits to define acceptability semantics sensitive to the existence of accruals between arguments. (...) The question of accruals arises in situations where several arguments defending the same position against another argument are unable to individually defeat this argument, but could do it collectively if they combine their strengths. We investigate some of the theoretical and computational properties of our new framework and semantics, and present a reasoning algorithm that is based on a translation of the problem into pseudo-boolean constraint satisfaction. This paper proposes an intuitive framework which allows strength compensations in an argumentation context where attacks may not succeed, completed by an approach which detects accruals throughout the reasoning process without requiring the elicitation of all compensatory combinations of arguments as an input.

A study is reported testing two hypotheses about a close parallel relation between indicative conditionals, if A then B , and conditional bets, I bet you that if A then B . The first is that both the indicative conditional and the conditional bet are related to the conditional probability, P(B|A). The second is that de Finetti's three-valued truth table has psychological reality for both types of conditional— true , false , or void for indicative conditionals and win , lose (...) , or void for conditional bets. The participants were presented with an array of chips in two different colours and two different shapes, and an indicative conditional or a conditional bet about a random chip. They had to make judgements in two conditions: either about the chances of making the indicative conditional true or false or about the chances of winning or losing the conditional bet. The observed distributions of responses in the two conditions were generally related to the conditional probability, supporting the first hypothesis. In addition, a majority of participants in further conditions chose the third option, “void”, when the antecedent of the conditional was false, supporting the second hypothesis. (shrink)

The rise of big digital data is changing the framework within which linguists, sociologists, anthropologists, and other researchers are working. Semiotics is not spared by this paradigm shift. A data-driven computational semiotics is the study with an intensive use of computational methods of patterns in human-created contents related to semiotic phenomena. One of the most promising frameworks in this research program is the Semantic Vector Space models and their methods. The objective of this article is to contribute to the exploration (...) of the SVS for a computational semiotics by showing what types of semiotic analysis can be accomplished within this framework. The study is applied to a unique body of digitized artworks. We conducted three short experiments in which we explore three types of semiotic analysis: paradigmatic analysis, componential analysis, and topic modelling analysis. The results reported show that the SVS constitutes a powerful framework within which various types of semiotic analysis can be carried out. (shrink)

The Bayesian model is used in psychology as the reference for the study of dynamic probability judgment. The main limit induced by this model is that it confines the study of revision of degrees of belief to the sole situations of revision in which the universe is static (revising situations). However, it may happen that individuals have to revise their degrees of belief when the message they learn specifies a change of direction in the universe, which is considered as changing (...) with time (updating situations). We analyze the main results of the experimental literature with regard to elementary qualitative properties of these two situations of revision. First, the order effect phenomenon is confronted with the commutative property. Second, an apparent new phenomenon is presented: the redundancy effect that is confronted with the idempotence property. Finally, results obtained in this kind of experimental situations are reinterpreted in the light of pragmatic analysis. (shrink)
