The paper studies a specific adaptive learning rule when each player faces a unidimensional strategy set. The rule states that a player keeps on incrementing her strategy in the same direction if her utility increased and reverses direction if it decreased. The paper concentrates on games on the square [0,1]×[0,1]\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$[0,1]\times [0,1]$$\end{document} as mixed extensions of 2×2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$2\times 2$$\end{document} games. We study in general the (...) behavior of the system in the interior as well as on the borders of the strategy space. We then describe the system asymptotic behavior for symmetric, zero-sum, and twin games. Original patterns emerge. For instance, for the “prisoner’s dilemma” with symmetric initial conditions, the system goes directly to the symmetric Pareto optimum. For “matching pennies,” the system follows slowly expanding cycles around the mixed strategy equilibrium. (shrink)

At M. Bernard's I saw several magnificent paintings on porcelain by Monsieur Constantin. In two hundred years, Raphael's frescoes will be known only through Monsieur Constantin.Stendhal, Voyage en France, 1837If we compare the forms that the act of copying has assumed in various civilizations, we cannot fail to notice that a certain number of phenomena are specific to European culture since the Renaissance. Perhaps one of the most singular of these phenomena is the will to create and to possess (...) imperishable reproductions of works that have been singled out, at a given moment, as the brightest jewels of Western art. The history of the fortune of Graeco-Roman sculptures has been masterfully related by Francis Haskell and Nicholas Penny in Taste and the Antique: The Lure of Classical Sculpture 1500-1900, even if it would no doubt be worthwhile to give further consideration to the critical fortune of materials used for reproduction, and particularly to the particular prestige attached to bronze—from the Mantuan works of Antico to the reconstitutions of Greek Urbilder in bronze, instead of the plaster used earlier, which were executed at the beginning of the twentieth century, such as the two Doryphoros that Georg Römer realized from various ancient marble copies of Polyclitus's athlete. But, in fact, it was not only in modern Europe that copies were made in bronze. The production of copies using this alloy was particularly prevalent in imperial China after the rediscovery, in the second half of the eleventh century of our era, of a collection of archaic bronzes from the Shang era. This is why I prefer to call attention to a practice that appears to me, in contrast, to be unique to the Western world: the copying of renowned paintings in materials that are supposed to defy time.

Ce livre est composé de chroniques destinées à la revue mensuelle du Rotary club de Colmar dont Bernard Pierrat est un ancien président. L'auteur porte un regard critique sur les informations recueillies dans de nombreux domaines pour apaiser les angoisses nées le plus souvent de l'ignorance. Les avancées fulgurantes de la science ont bouleversé les repères auxquels nous nous référions dans notre approche du réel. Nous sommes sans cesse confrontés à des questions nouvelles qui sollicitent notre curiosité, ce sel (...) de l'esprit. Nourri de la pensée de Teilhard de Chardin, l'auteur propose d'analyser avec lucidité les pistes d'un avenir au service de l'humain et tente d'actualiser la devise du Rotary international " Servir " destinée à favoriser la compréhension entre les Hommes et aider chacun à être plus ouvert sur le monde et sur les autres.

Time is analyzed as being those processes by which a system notes the processes which comprise its own existence. The directionality of time is given by the concepts, past, present, and future. To understand the meaning of these concepts, a set of experiments was carried out with four male subjects in which areas of time were expanded or ablated by means of post-hypnotic suggestions. These operations were carried out singly or in combination. The data suggest that the present is primarily (...) associated with stimulus input, the past with the criteria for defining that input as well as the development of response inhibitions and the future with the directionality of that input. Marked personality changes which range from the occurence of catatonic-like states to obsessive types of reaction and manic-like reactions are associated with different combinations of time alterations. Some of the changes are in accord with the serialist position on time of J. W. Dunne. The concept of death is very important both with regard to one’s view of time and how one lives. While it is important to live in the present, the present has no meaning without at least a past or a future. Implications of these findings for psychopathology in general and schizophrenia in particular are considered. (shrink)

_Nulla dies sine linea_ « Regarde de tous tes yeux, regarde » « Travaille ton instrument » Essentielle à toute activité artistique, la pratique d’exercices est pourtant rarement interrogée en tant que telle. Qu’est-ce qu’un exercice artistique? Quelles perspectives la pensée de l’exercice permet-elle d’ouvrir sur la compréhension des pratiques artistiques, sur leurs liens avec les savoirs et les techniques, sur leur dimension historique et sociale, sur les valeurs de transmission qu’elles font vivre? Réactivée dans la philosophie contemporaine, la notion (...) d’exercice n’est pourtant que rarement confrontée aux pratiques artistiques et aux élaborations théoriques de ces pratiques. Or l’artiste, c’est d’abord une femme ou un homme qui, pour faire et pour produire, doit s’exercer, et s’exercer sans relâche. Exercices d’apprentissage et de formation, antérieurs à l’œuvre ; e...

This paper explores a remarkable convergence of ideas and evidence, previously presented in separate places by its authors. That convergence has now become so persuasive that we believe we are working within substantially the same broad framework. Taylor's mathematical papers on neuronal systems involved in consciousness dovetail well with work by Newman and Baars on the thalamocortical system, suggesting a brain mechanism much like the global workspace architecture developed by Baars (see references below). This architecture is relational, in the sense (...) that it continuously mediates the interaction of input with memory. While our approaches overlap in a number of ways, each of us tends to focus on different areas of detail. What is most striking, and we believe significant, is the extent of consensus, which we believe to be consistent with other contemporary approaches by Weiskrantz, Gray, Crick and Koch, Edelman, Gazzaniga, Newell and colleagues, Posner, Baddeley, and a number of others. We suggest that cognitive neuroscience is moving toward a shared understanding of consciousness in the brain. (shrink)

Marqués par Descartes et Locke, les philosophes de ce siècle se sont notamment intéressés à l'épistémologie devenue alors discipline philosophique fondamentale.

Avant de s'inquiéter de la variété des perversions et même de la volonté perverse, l'auteur s'interroge sur l'énigme de la volonté, sur la lente émergence de sa reconnaissance explicite. Non pour opérer une réduction historienne, morale ou psychopathologique, mais pour mieux approcher la perversion comme intensité. La perversion n'est pas une simple perturbation de la finalité supposée du désir ni seulement l'expression d'une défaillance, mais d'abord une forme d'affirmation de la volonté libre, une intensification qui affecte aussi bien le rapport (...) au fini que celui à l'infini. Oui. la volonté perverse est révélatrice du dépassement que la liberté désire introduire dans les hasards et les nécessités de l'opinion, des lois et des sciences physiques, humaines ou théologiques ; elle est aspiration à toujours plus d'accomplissement de soi. l'impuissance à saisir le moment favorable est le coeur de la perversion : non pas avant tout une méprise d'objet. La perversion de la volonté libre est d'abord une intensité de fixation sur le bonheur voulu immédiatement et en soi, et non par égard à ce qui advient. Une réflexion qui vient à point nommé. (shrink)
