ABSTRACTNegative emotions typically have an adverse effect on reasoning, especially analytic or logical reasoning. This effect can be explained using an attentional framework in which emotion detracts limited-capacity cognitive resources which are required for reasoning. Another possibility is that the effect of emotion on reasoning is mediated by arousal, as previous research has shown that physiological arousal can be associated with decreased reasoning performance. In this research, we used a dual-task paradigm combining a syllogistic reasoning task and a time production (...) task. Prospective timing allows to disentangle the effects of attention and arousal: time productions should lengthen if emotion takes up cognitive resources that are therefore not available for timing, whereas time productions should shorten if emotional reasoning results from increased arousal. Results from two experiments confirm the adverse impact of emotion on logical reasoning performance. Reasoning about emotional contents led t... (shrink)

This article compares the features of a logic of discovery for the "friends of discovery" and for Karl Popper. It argues that the account given by Popper is the same as that of the "friends of discovery." The comparison will unsystematically exhibit that Popper proposes such a logic and will submit that the epistemological significance of a logic of discovery is to be sought in a configuration of ideas and transactions deemed regulated by or mirroring rationality rather than in creative (...) processes as such.

On rencontre encore cette idée d'une triple révolution: Copernic, Darwin, Freud. La première phase fera l'objet de nos réflexions. Elle a été conçue par Freud comme une blessure au narcissisme humain. « Le narcissisme universel des hommes, leur amour d'eux-mêmes, nous dit Ricœur expliquant Freud, a, jusqu'à présent, subi trois sévères coups de la part de la science: ce fut d'abord la position centrale de la terre qui fut contesée par Copernic, puis … « Freud lui-même nous dit que pour (...) l'homme pré-copernicien » la position centrale de la terre indiquait qu'elle jouait un rôle dominant dans l'univers et concordait avec la tendance qu'il avait à se considérer comme maître du monde «. Et à l'époque de Freud des historiens de la science abondèrent dans le même sens: au « moyen âge », la terre et l'homme étaient au centre de l'univers et cette position était la plus honorable.

Il peut sembler incongru de supposer qu'il y a une identité entre l'histoire de la science et l'histoire d'une idéologie C'est pourtant ce que donne à penser, comme on le verra, une comparaison entre la notion kuhnienne de paradigme et la notion d'idéologie. Une relation a déjà été établie entre les deux notions. Nous croyons qu'elle reste superficielle et ne conduit qu'à une compréhension négative. On pose cette relation pour dire que chez Kuhn le paradigme détermine le comportement de la (...) communauté scientifique à la manière de l'idéologie, au sens péjoratif du terme, c'est-à-dire d'une façon dogmatique, aveugle et passionnée, produisant des décisions irrationnelles et sectaires. Notre intention est d'abord d'expliciter la relation entre la notion kuhnienne de paradigme et la notion d'idéologie. Trois résultats sont visés. En premier lieu, il s'agit de donner plus de signification à cette relation et de la préciser. En second lieu, de contribuer à l'étude du problème de la justification en science, tel qu'il peut se poser à partir de Kuhn. En troisième lieu, de montrer que, dans la mesure où la description de Kuhn est convaincante, et où la relation que nous analysons est fondée, la séparation entre la science et l'idéologie est à repenser.

La révolution scientifique ou copernicienne apparait habituellement au penseur comme un événement imposant, complexe et problématique. Mais ce ne semble pas être le cas pour M. Raymond Montpetit. Vous n'avez, selon lui, qu'è y appliquer un regard dialectique on psychanalytique et le tour est joué. C'est ce que je retiens de l'allure et du biais de sa discussion de mon article sur la révolution en question.

This book establishes the connection between the evolutionary scientific ideas of The Human Phenomenon and the Christian spirituality and theology of The Divine Milieu.

The authors offer a "first" summary of Teilhard's thoughts on love, a central element in his evolutionary spirituality, presented in accessible language for the ordinary reader. They explore the implications of Teilhard's evolutionary perspective on love as it affects friendships, marriages, parent-child relationships, and teams (larger groups).

This paper presents and examines the interreligious philosopher-theologian Raimon Panikkar’s proposal of ‘Cosmic Confidence’ in interreligious spirituality and another dialogue theologian Paul Knitter’s critique on it. Their conversation is to be situated in a wider issue of the relation between pluralism and justice. The paper proceeds in three parts. The first part summarily presents the context and direction of Panikkar’s pluralistic vision, particularly with a focus on his central insight of cosmic confidence. The second part indicates a challenge to Panikkar’s (...) cosmic confidence in terms of a preferential option for the poor – a spirit, of course, of liberation theology, but also that gets reflected in the challenge thrown by Knitter. And the final part deals with some implications of their mutual dialogue for the issue of pluralism, justice and reconciliation. (shrink)

In 1837 the German-born astronomer F. G. W. Struve published his famous catalogue of double stars. For Struve this was the culmination of 12 years' detailed observation of a class of celestial objects lying exclusively beyond the solar system; for historians of astronomy it poses the problem of explaining why the study of double stars became a significant part of astronomical endeavour, as it did, during the 1820s and 1830s. For, although Struve's interest was extreme, it was shared to a (...) lesser extent by several eminent contemporaries, including John Herschel, Friedrich Bessel, Johann Encke, James South and Félix Savary. Their combined efforts represented an important transition in astronomy: for the first time one of the emphases of the subject moved beyond the solar system to the so-called fixed stars. The question of the emergence of interest in double stars is of historical significance, therefore, as it is related to the problem of the origins of ‘stellar astronomy’. This essay is thus intended to offer an explanation of astronomers' interest in double stars, and to tackle the related question of whether this transition constituted a major break in the history of astronomy. Furthermore it is proposed that answers to these problems may be found by considering the practice of astronomy dominant during the first half of the nineteenth century. Astronomers in this period were overwhelmingly concerned with a refined form of positional astronomy. The problems they chose to solve were by and large related to the difficulties of the accurate reduction of observational data, and the compilation of reliable tables and star charts, which were then used as a background against which the motions of solar system objects were plotted. By assessing individuals' studies of double stars within this context it can be seen firstly that such studies were no more or less than specific examples of a general case, and secondly that the stars themselves were not usually of intrinsic interest. In general it was the positions of the stars on the. (shrink)

This article explores the relation between the concept of symmetry and its formalisms. The standard view among philosophers and physicists is that symmetry is completely formalized by mathematical groups. For some mathematicians however, the groupoid is a competing and more general formalism. An analysis of symmetry that justifies this extension has not been adequately spelled out. After a brief explication of how groups, equivalence, and symmetries classes are related, we show that, while it’s true in some instances that groups are (...) too restrictive, there are other instances for which the standard extension to groupoids is too un restrictive. The connection between groups and equivalence classes, when generalized to groupoids, suggests a middle ground between the two. *Received July 2007. †To contact the authors, please write to: Alexandre Guay, UFR Sciences et Techniques, Université de Bourgogne, 9 Avenue Alain Savary, 21078 Dijon Cedex, France; e‐mail: [email protected] ; or to Brian Hepburn, Department of Philosophy, University of British Columbia, 1866 Main Mall E370, Vancouver, BC, Canada V6T 1Z1; e‐mail: [email protected].

To what extent are non human alterities in contemporary Brazilian literature? How have some Brazilian writers dealt with the paradoxical relations between humanity and animality, as well as with ethno-ecological problems proper to our time? This article addresses the presence of non human beings in works by Nicanor Sena, Astrid Cabral, Olga Savary, Sérgio Medeiros and Josely Vianna Baptista, in the light of a transdisciplinary theoretical framework that includes thinkers such as Ailton Krenak, Eduardo Viveiros de Castro, Dominique Lestel (...) and Donna Haraway. The article also deals with the cultural and textual hybridity that cuts through the works of some authors of our literary repertoire. I thereby show how they present a liminal nature, with a strong transnational bent, as they are shot through by mythological and zoological elements, indigenous legends, diverse literary references, and different geographical and linguistic spaces.

Em que medida as alteridades não humanas se inscrevem na literatura brasileira contemporânea? Como alguns escritores brasileiros têm lidado com as relações paradoxais entre humanidade e animalidade, bem como com os problemas ecológicos do nosso tempo? Este artigo aborda a presença dos seres não humanos em obras de Nicanor Sena, Astrid Cabral, Olga Savary, Sérgio Medeiros e Josely Vianna Baptista, à luz de um referencial teórico transdisciplinar, que inclui pensadores como Ailton Krenak, Eduardo Viveiros de Castro, Dominique Lestel e (...) Donna Haraway. Outro tópico desenvolvido é o hibridismo cultural e textual que atravessa os trabalhos de alguns dos autores incluídos no repertório literário, de forma a mostrar como eles apresentam um caráter fronteiriço, com um forte viés transnacional, por estarem atravessados por elementos zoológicos e mitológicos, lendas indígenas, referências literárias diversas e diferentes espaços linguístico-geográficos.
