When testing primates with cognitive tasks, it is usually not considered that subjects differ markedly in terms of emotional reactivity toward the experimenter, which potentially affects a subject’s cognitive performance. We addressed this issue in common marmosets (Callithrix jacchus), a monkey species in which males tend to show stronger emotional reactivity in testing situations, whereas females have been reported to outperform males in cognitive tasks. In a two-phase experiment, we first quantified the emotional reactivity of 14 subjects toward four different (...) experimenters performing a standardized behavioral action sequence and then assessed whether and how it affected the subjects’ participation and performance in a subsequent object permanence task. A test session was terminated if a subject refused to make a choice in four consecutive trials. Highly emotionally aroused individuals, particularly males, were less likely to participate in the cognitive task and completed fewer trials. However, whenever they did participate and were attentive to the task, their performance was not affected. Our results suggest that differences in emotional reactivity toward an experimenter have no major impact on cognitive performance if strict criteria are applied on when to abandon a test session and if performance is corrected for attention to the test procedure. Furthermore, they suggest that the reported sex differences in cognitive performance in marmosets may be owing to motivational and attentional factors, rather than a difference in cognitive ability per se.

André Tosel, décédé en mars 2017, était un philosophe engagé, attaché tout au long de son existence à faire vivre un marxisme critique puisant notamment dans le meilleur de la tradition italienne de ce courant de pensée ; il fut l'un des rares français à introduire et discuter les oeuvres majeures d'A. Labriola et surtout d'A. Gramsci, ainsi par ailleurs que celles de Vico dont il fut un fin connaisseur. Il consacra sa thèse de doctorat d'état aux rapports entre religion, (...) politique et philosophie chez Spinoza et contribua de façon décisive à de nouvelles lectures du philosophe en le mettant en miroir de Marx. Professeur de philosophie des universités de Besançon, Franche Comté, de Paris 1 Panthéon-Sorbonne et de Nice Sophia-Antipolis, dans lesquelles il occupa de nombreuses fonctions de directions administratives et scientifiques, il était un homme de collectif attaché à faire vivre le savoir, s'engageant dans la vie universitaire et politique, contribuant également de manière décisive au lancement et à l'animation de la revue Actuel Marx. Passionné par l'évolution des pensées contemporaines, il intervenait régulièrement dans des débats d'actualité, sous la forme de contributions dans L'Humanité ou dans des ouvrages destinés à un public large, tout particulièrement dans la dernière période sur les questions de sécularisation, de laïcité et de religion. Cet ouvrage entend lui rendre hommage en abordant les différentes facettes de son oeuvre, traversant un demi-siècle de vie intellectuelle. (shrink)

Einige versuchen, Wunder mit den Naturgesetzen vereinbar zu machen, indem sie „Wunder“ als etwas anderes als göttliche Eingriffe definieren. Dieser Aufsatz behauptet hin- gegen, daß Wunder die Naturgesetze nicht verletzen, obwohl sie göttliche Eingriffe sind. Wunder sind auch keine „Ausnah- men“ der Naturgesetze, noch treffen die Naturgesetze nicht auf sie zu. Naturgesetze haben nie Ausnahmen, sie werden nie verletzt oder ausgesetzt, sie sind wahrscheinlich notwen- dig und unveränderlich, und sie treffen auch auf göttliche Ein- griffe zu. (...) Wir sollten nicht unsere Vorstellung von Wundern, sondern unsere Vorstellung der Naturgesetze in Frage stel- len. Die Hauptthese dieses Aufsatzes ist, daß Naturgesetze keine Abfolgeregelmäßigkeiten implizieren und daß deshalb Wunder die Naturgesetze nicht verletzen. Wir brauchen eine neue Theorie der Naturgesetze: die Tendenztheorie. (shrink)

Coercion and the State: A review of B Sharon Byrd and Joachim Hruschka, Kant's Doctrine of Right: A Commentary by Helga Varden.

This volume gathers contributions at the intersection of history and politics. The essays, covering such topics as diverse as Italian identity in the Tientsin concession, international refugee policies in the interwar period and after, and the myths and realities of the Ukranian-Russian encounter in independent Ukraine, show that history provides better grounding as well as a more suitable paradigm for the study of politics than economics or other hard sciences. All of the contributors have a common link - doctoral work (...) supervised and shaped by Professor Andre Liebich - but have since expanded widely in the world. Hence, the authors of this work at once share a common base and yet benefit from diverse viewpoints. (shrink)

Tyler Andrew Wunder, in his article, “Alvin Plantinga on Paul Draper’s evolutionary atheology: implications of theism’s non-contingency,” argues that Plantinga makes a serious error regarding probabilities in his critique of Draper. Properly modified, Wunder believes the argument “works,” but only in a trivial sense. This paper argues that Wunder’s objection, based on an assumed probability calculus, is merely asserted; whereas, there are other competing axiomatic systems consistent with Plantinga’s treatment of probability. As to the modified argument, it (...) is demonstrated that Wunder mistakenly concludes that two key propositions are contradictory. The consequence of this is not that Plantinga’s argument “works” in a trivial sense, but rather that the argument becomes incoherent. Lastly, this paper will explore the consequences of both Wunder’s and Plantinga’s assumptions concerning conditional probability for Draper’s evidentiary argument and Plantiga’s Evolutionary Argument Against Naturalism.

The paper sets out and defends against criticism the claims argued for in the book A minimalist ontology of the natural world.

Working in Germany between the two world wars, John Heartfield developed an innovative method of appropriating and reusing photographs to powerful political effect. As a pioneer of modern photomontage, he sliced up mass media photos with his iconic scissors and then reassembled the fragments into compositions that utterly transformed the meaning of the originals. In John Heartfield and the Agitated Image, Andrés Mario Zervigón explores this crucial period in the life and work of a brilliant, radical artist whose desire to (...) disclose the truth obscured by the mainstream press and imperial propaganda made him a de facto prosecutor of Germany’s visual culture. Zervigón charts the evolution of Heartfield’s photomontage from an act of antiwar resistance into a formalized and widely disseminated political art in the Weimar Republic. Appearing on everything from campaign posters to book covers, the photomonteur’s notorious pictures challenged well-worn assumption and correspondingly walked a dangerous tightrope over the political, social, and cultural cauldron that was interwar Germany. Zervigón explains how Heartfield’s engagement with montage arose from a broadly-shared dissatisfaction with photography’s capacity to represent the modern world. The result was likely the most important combination of avant-garde art and politics in the twentieth century. A rare look at Heartfield’s early and middle years as an artist and designer, this book provides a new understanding of photography’s role at this critical juncture in history. (shrink)

" Au bas de la statue d'Auguste Comte, place de la Sorbonne, à Paris, on pouvait lire récemment - et peut-être le peut-on encore : "Ni Comte ni Sponville". Ce graffiti exprime à sa manière l'un des grands défis de la philosophie française de cette fin de siècle, à savoir celui de sa popularité. Car la philosophie est désormais au centre de la vie publique : elle trône dans les cafés, se fait une place dans l'entreprise et s'installe même dans (...) les cabinets privés. Mais ce qui ne laisse pas d'étonner, c'est l'écho qu'elle rencontre auprès d'un grand public avide de lectures philosophiques. Il convient de s'interroger sur cet engouement, ou plutôt d'interroger les philosophes à ce sujet, eux qui sont sans doute les mieux placés pour y répondre. " Précédés d'une introduction à l'œuvre des auteurs interviewés, les six entretiens réunis dans ce livre font le point à la fois sur la pensée de chacun d'eux et sur la situation générale de la philosophie française actuelle. Bien qu'on n'ait dans aucun sens affaire ici ni à une école ni à une improbable " pensée 98 ", il se dégage quand même de ces rencontres l'image d'une philosophie qui a renoué avec la vie, qui est arrivée à reformuler, à nouveaux frais, les questions de la philosophia perennis et qui a rétabli le dialogue avec son temps.

James Beilby’s Epistemology as Theology is the first monograph to address Alvin Plantinga’s completed Warrant Trilogy. The book provides a thorough introduction to Plantinga’s current religious epistemology, but readers hoping for a critical treatment of Plantinga will be largely disappointed: while Beilby does level criticisms against Plantinga, he often underestimates their significance. One of Beilby’s main goals is to sketch out how a version of Reformed epistemology, even if not exactly Plantinga’s version, can withstand its critics. I provide a chapter-by-chapter (...) examination of Beilby’s book, and argue his defense of Reformed epistemology is not obviously a significant improvement over Plantinga’s. (shrink)

This paper is a response to Tyler Wunder’s ‘The modality of theism and probabilistic natural theology: a tension in Alvin Plantinga's philosophy’ (this journal). In his article, Wunder argues that if the proponent of the Evolutionary Argument Against Naturalism (EAAN) holds theism to be non-contingent and frames the argument in terms of objective probability, that the EAAN is either unsound or theism is necessarily false. I argue that a modest revision of the EAAN renders Wunder’s objection irrelevant, (...) and that this revision actually widens the scope of the argument. (shrink)

In this article I respond to Yuk Hui by revisiting the crossroads in the philosophy of technology as represented by the philosophies of Stiegler and Ihde. Whereas Hui proposes the concept of cosmotechnics as an integrating perspective, I conceive of the crossroads in other terms, namely from the perspective of substantivism. I characterize our present situation, what a philosophy of technology should address and then examine Hui’s notion of cosmotechnics from this alternative perspective. My main concern is to show future (...) paths of development for cosmotechnical thought. (shrink)

Compared to existing classical approaches to semiotics which are dyadic (signifier/signified, F. de Saussure) and triadic (symbol/concept/object, Ch. S. Peirce), this theory can be characterized as tetradic ([sign/semion]//[object/noema]) and is the result of either doubling the dyadic approach along the semiotic/ordinary dimension or splitting the ‘concept’ of the triadic one into two (semiotic/ordinary). Other important features of this approach are (a) the distinction made between concepts (only functional pairs of extent and intent) and categories (as representations of expressions) and (b) (...) the indication of the need for providing the mathematical passage from the duality between two sets (where one is a singleton) within systems of sets to category-theoretical monoids within systems of categories while waiting for the solution of this problem in the field of logic. Last but not least, human language expressions are the most representative physical instances of semiotic objects. Moreover, as computational experiments which are possible with linguistic objects present a high degree of systematicity (of oppositions), in general, it is relatively easy to elucidate their dependence on the concepts underlying signs. This new semiotic theory or rather this new research program emerged as the fruit of experimentation and reflection on the application of data science tools elaborated within the frameworks of Rough Set Theory (RST), Formal Context Analysis (FCA) and, though only theoretically, Distributed Information Logic (DIL). The semiotic objects (s-objects) of this theory can be described in tabular datasets. Nevertheless, at this stage of formalisation of the theory, lattices (not trees) can be used as working representation structures for characterizing the components of concept systems and graphs for categories of each layer.
