Résumé : Les fondateurs du socialisme ont en commun de penser l'avènement d'une coupure historique, d'une révolution marquant le début d'un nouveau monde riche de rythmes temporels sans précédents. Mais leurs constructions des temps sociaux divergent profondément. Saint-Simon, puis Eugène Buret, Constantin Pecqueur, font du passé de l'Europe un temps scandé par la succession de systèmes (...) - XIXe (...) siècle – Nouvel article. (shrink)

This paper argues that proper names may have literal non-referential truth-conditional values, thereby undermining the notion of semantic reference.

De acordo com a constatação deNietzche, segundo a qual o destino da filosofiaestá ligado ao da música, devemos nos perguntaro que a fenomenologia traz para a compreensãodo fenômeno sonoro. Trata-se dedesenvolver a fenomenologia da consciênciaíntima do tempo, levando-se em conta a riquezado material musical. Este material se organizaem torno de noções, aparentemente independentesumas das outras, mas de fato essencialmenteligadas, de ritmo e de surpresa. Oconceito central que emerge desta pesquisanão é mais o de sentimento,mas de atenção. Husserl limitava este conceitoao (...) domínio da modificação imaginadora daexperiência vivida. (shrink)

This article examines how the theory of proportions was explained during the second half of the seventeenth century in the works of Andreas Tacquet, Antoine Arnauld, Ignace Gaston Pardies, Bernard Lamy, and Jacques Rohault. These five authors had very different conceptions of this subject, and on one hand, they show that this question was not forgotten, even after the Geometry of Descartes, and on the other hand, their work displays the progressive transformation of mathematical objects. While Tacquet deepened Euclidean thought, (...) the others stopped taking the Euclidean model as paradigmatic and tried to change the order of the Elements and to establish book V of Euclid in new ways. We shall see that this multiplicity of the approaches highlights both the vitality of the reflections and the difficulty in developing a new ontology of mathematics. Some of them nevertheless opened new perspectives that were to bloom only much later. We shall also see the increasingly important place of the algebra as time went by. (shrink)

We prove a couple of results on NTP2 theories. First, we prove an amalgamation statement and deduce from it that the Lascar distance over extension bases is bounded by 2. This improves previous work of Ben Yaacov and Chernikov. We propose a line of investigation of NTP2 theories based on S1 ideals with amalgamation and ask some questions. We then define and study a class of groups with generically simple generics, generalizing NIP groups with generically stable generics.

We prove in particular that, in a large class of dp-minimal theories including the p-adics, definable types are dense amongst nonforking types.

This paper is concerned with adaptive learning and coordination processes. Implementing agent-based modeling techniques (Learning Classifier Systems, LCS), we focus on the twofold impact of cognitive and environmental complexity on learning and coordination. Within this framework, we introduce the notion of Adaptive Learning Agent with Rule-based Memory (ALARM), which is a particular class of Artificial Adaptive Agent (AAA, Holland and Miller 1991). We show that equilibrium is approached to a high degree, but never perfectly reached. We also demonstrate that memorization (...) and learning capacities depend upon the relative discordance between the cognitive complexity of agents' mental models and the degree of stability of the environment.

Belle van Zuylen dicteerde haar brief aan haar neef toen deze bij haar in Frankrijk verbleef. Zij was al sinds zijn geboorte betrokken geweest bij zijn opvoeding, als raadgeefster van haar broer, de vader van Willem-René. Na de Franse Revolutie kon de jongeman geen aanspraak meer maken op de voorrechten van zijn adellijke geboorte, maar zou zichzelf met werken een plaats in de maatschappij moeten veroveren.

As stressed by Perruchet & Vinter, the SOC model echoes Johnson-Laird's mental model theory. Indeed, the latter rejects rule-based processing and assumes that reasoning is achieved through the manipulation of conscious representations. However, the mental model theory as well as its modified versions resorts to the abstraction of complex schemas and some form of implicit logic that seems incompatible with the SOC approach.

Aragon lived through two wars directly, and his relationship with them was different: most of what he wrote about the First World War was written forty years later, in Le Roman inachevé, whereas the Second World War led immediately to the poems of Crève-Cœur and Les Yeux d’Elsa, and then to those of the Resistance. A different relationship to time, then. But precisely because of the upheavals it brought to both historical and everyday experience, the illusions it shattered and the (...) heartbreak it caused, the war immediately confronted the poet with a diffraction of temporality: the time of boredom and forced inaction, time of death, setting in time of repetition, time of life slipping away. Occasionally, also, time of hope. (shrink)

Ivre de Dieu, Giordano Bruno nous offre une presentation violemment heterodoxe des dogmes chretiens, moins pour les destituer de leur autorite que pour les faire fonctionner autrement.
