The usual action integral of classical electrodynamics is derived starting from Lanczos’s electrodynamics – a pure field theory in which charged particles are identified with singularities of the homogeneous Maxwell’s equations interpreted as a generalization of the Cauchy–Riemann regularity conditions from complex to biquaternion functions of four complex variables. It is shown that contrary to the usual theory based on the inhomogeneous Maxwell’s equations, in which charged particles are identified with the sources, there is no divergence in the self-interaction (...) so that the mass is finite, and that the only approximations made in the derivation are the usual conditions required for the internal consistency of classical electrodynamics. Moreover, it is found that the radius of the boundary surface enclosing a singularity interpreted as an electron is on the same order as that of the hypothetical “bag” confining the quarks in a hadron, so that Lanczos’s electrodynamics is engaging the reconsideration of many fundamental concepts related to the nature of elementary particles.

The author explores with the leading scholars of today the way and extent to which many forms of oppression, such as racism, classism, capitalism, sexism, and linguicis, have affected the women, poor working-class people, queer people, students of color, female faculty and faculty of color. The leading scholars are: Richard Delgado, David Gillborn , Zeus Leonardo, Antonia Darder, Howard Winant, Christine Sleeter, Sonia Nieto, Carl Grant, Peter McLaren, Noam Chomsky, Eduardo Bonilla-Silva, Pedro Noguera, and Dave Stovall. Sometimes immensely personal, the (...) interviews unveil the how far America has come, and just how far we have to go, in the quest for equality for all its citizens. (shrink)

A presentation and discussion of Gottlob Frege's understanding of language, both natural and artificial, with close attention to his texts.

Les émotions ont un rôle important dans nos interactions sociales. Sans émotions, nous avons du mal à faire des choix. Quand notre environnement déçoit nos attentes de manière répétée, nos émotions nous signalent qu'il serait rationnel de changer nos attentes, c'est-à-dire de procéder à des révisions. Le partage des émotions, qui est la clé de notre sentiment d'appartenance à une communauté, nous amène à révéler nos valeurs, parce qu'il permet de résister face à un monde décevant. Si même une fois (...) révisées nos croyances, nos émotions se maintiennent, elles manifestent alors des attentes bien enracinées, qui sont nos valeurs réelles. Pour étudier les valeurs collectives, il faut donc étudier les émotions, la manière dont elles incitent à des révisions, et comment leur partage collectif renforce nos résistances. La rationalité morale s'appuie sur les émotions. Celles-ci sont sensibles aux détails des situations, et cette rationalité dépend des contextes, si bien qu'elle propose des arguments qui restent révisables quand le contexte change. Ne résistent à toute révision que nos sentiments d'injustice. L'originalité de ce livre est donc d'étudier les émotions et les valeurs, individuelles et collectives, dans la dynamique de leurs changements, de leurs révisions et de leurs résistances, et d'utiliser ce lien entre émotions et révisions pour mieux définir la spécificité d'une rationalité morale.

Drawing on various resources and requirements (as expressed by Dewey, Wittgenstein, Sellars, and Brandom), this paper proposes an externalist view of conceptual mental episodes that does not equate them, even partially, with vehicles of any sort, whether the vehicles be located in the environment or in the head. The social and pragmatic nature of the use of concepts and conceptual content makes it unnecessary and indeed impossible to locate the entities that realize conceptual mental episodes in non-personal or subpersonal contentful (...) entities (vehicles). Persons, who engage in social practices of deontic scorekeeping (Brandom), and who are thus able to produce appropriate inferential behaviour, enact conceptual mental episodes and the basis of their supervenience.

The dissertation seeks to gain a comprehensive understanding of Frege's watershed work of logic, the 1879 Begriffsschrift . The treatise is the first since Aristotle's instauration of the discipline to have succeeded in completely recasting logic. Very generally stated, the dissertation aims at making explicit the conceptual origins of modern logic. To do that will require that each of the achievements of Concept-script be examined from one or more vantage points: either within the perspective of Frege's larger and guiding ambition, (...) that of providing a logical justification of arithmetic; or with respect to the horizon of modernity; or in relation to later developments in logical theory and the philosophy of language, developments stimulated, albeit not exclusively, by Frege's very work. The vantage point adopted in each case will depend on the nature of the topic and the extent to which it requires to be made explicit. One perspective will have preponderance, that of Frege's relationship to his early modern ancestors, a group that includes philosophers, scientists, and mathematicians. Since modernity is constituted in a nearly constant critical, if not polemical, relationship to the Ancients, they will also at times be drawn into the discussion. The elucidation of Frege's breakthrough work will be guided by the following thesis: Frege's attempt to justify arithmetic logically and the fine work of clarification he produced in actualizing this project; his discovery of function-theoretic logic and his fashioning of a concept-script ; and his critique of natural language and the attendant semantics developed over the course of that critique constitute an unfolding and an extension of the primacy of universal method over ontology that is the signature of modern inquiry.

En 1777, alors que la France et la Grande-Bretagne sont en guerre aux Amériques, un Français est reçu franc-maçon outre-Manche. À cette occasion, l’orateur de la loge prononce un discours qui traduit bien l’état d’esprit des fondateurs de la République universelle des francs-maçons : Toi, notre frère, natif et sujet d’un autre royaume, puissant et éclairé, en entrant dans notre Ordre, tu viens de contracter des liens sacrés et amicaux avec des milliers de maçons dans cette nation et bien d’a...

Dans ce livre savant et moqueur, Pierre-André Taguieff passe au scalpel l'idéal moderne par excellence, celui d'émancipation, qui exalte, mobilise et aveugle depuis longtemps les Modernes. Le temps est venu de soumettre à un examen critique sans complaisance cette notion qui fait partie du prêt-à-penser dont se sont emparés les utopistes et les démagogues de toutes obédiences. Comment expliquer que cette notion banale ait pu devenir un thème philosophique et politique majeur depuis la fin du XVIIIe siècle, sous la (...) forme du projet universaliste de l'émancipation du genre humain comme sous celle de l'autonomie croissante de l'individu? Taguieff analyse la formation philosophique de l'idée d'émancipation, explore ses usages politiques et dissèque ce qu'il appelle "l'émancipationnisme ", produit de la corruption idéologique de cette idée-force. Car l'émancipation comme projet global appelle une critique fondamentale : ce qui est rejeté subrepticement, voire diabolisé, ce sont les attachements, les fidélités, les enracinements, les mémoires particulières, donc la transmission. Il s'agit d'un programme de refonte anthropologique, visant à créer l'" homme nouveau ", chimère d'une société mondiale d'individus également émancipés. La généalogie d'une idée floue, pour penser librement le monde de demain. (shrink)

Les sociologues n'ont jamais cessé d'exprimer leur intérêt pour le problème dit de « la nature de la réalité sociale ». Pour nombre d'entre eux, le projet de clarifier ce problème n'est rien de moins que le programme complet de leur discipline. Mais la controverse autour de la nature de la réalité sociale est très loin d'être réglée. Des conceptions diamétralement opposées s'y affrontent, les unes « réalistes », les autres « anti-réalistes ». Ce genre de controverse, relatif à l'existence (...) ou à la non-existence de certaines entités (l'individu et la société, par exemple), et aux relations de dépendance ou de priorité entre elles, peut être dit « métaphysique ». Dans ce débat, certains des arguments requièrent une enquête sur la signification de termes centraux – « existence », « état de choses », « mental », « physique », « social », etc. –, et sur la détermination de leurs relations. On peut appeler « ontologiques » les recherches relatives à ces termes centraux. Elles contribuent à spécifier le mode d'existence des objets sociaux. C'est à la présentation de telles recherches qu'est consacré le présent volume. Son idée principale est qu'une enquête ontologique, ouverte à l'imagination et à l'invention, peut, en enrichissant l'ontologie mobilisée, sortir la querelle sur « la nature de la réalité sociale » de certaines de ses impasses.

: According to Dewey inquiry proceeds from uncertainty to integration and control. Even if Dewey pays attention to the incompleteness of nature, to the modification and revision of primary generalizations by more elaborated conceptions, to the necessity of introducing changes in the world in order to carry an experimental inquiry, to the possibility of re-determine the interdependent constituents in a "transaction", he seems not to be aware of the instability that this process of revision implies: we do not know in (...) advance whether a newly undertaken revision is a progress or a waste of time. If we accept this consequence of pragmatism, how can we be confident in the truth of our beliefs, if we know in advance that most of them are to be revised, and that even if our belief is by chance a really true one, it could be reasonable some day to pay attention to some counter-argument that would induce us to revise it. How can be maintained the practical force of an obligation, if all norms are to be revised someday, and if we never know whether our favorite norms are really not been revised? The stability that pragmatism seems to aim at could be obtained by studying the relation between two opposite revisions, where some properties of symmetry and fairness can be required and defined, in a "transactional" fashion that is reminiscent of Dewey. When these properties are not satisfied, it will be true forever that we are and will be entitled to require a revision of the situation. But then, the core of pragmatism is the revolt against what is unfair, a negative content. On the contrary, Dewey has always insisted upon the positive effect of negative situations, seeing failure as learning and negation as positive determination.Key-words: pragmatism, Dewey, inquiry, revision, ethics, democracy, transaction.Resumo: Segundo Dewey, a investigação procede da incerteza à integração e ao controle. Mesmo Dewey prestando atenção à incompletude da natureza, à modificação e revisão das generalizações por concepções mais elaboradas, à necessidade de introduzir mudanças no mundo de forma que conduza a uma investigação experimental, à possibilidade de re-determinar os constituintes interdependentes em uma "transação", ele parece não estar consciente da instabilidade que esse processo de revisão implica: nós não sabemos de antemão se uma nova revisão realizada é um progresso ou uma perda de tempo. Se aceitarmos essa conseqüência do pragmatismo, como podemos estar confiantes na veracidade de nossas crenças, já que sabemos de antemão que a maior parte delas deverá ser revisada? E mesmo se nossa crença for efetivamente verdadeira, poderia ser razoável algum dia prestar atenção a algum contra-argumento que poderia induzir-nos a revisá-la. Como pode ser mantida a força prática de uma obrigação, se todas as normas deverão ser revisadas algum dia, e se nunca sabemos se nossas normas favoritas não estão efetivamente sendo revisadas? A estabilidade que o pragmatismo parece buscar poderia ser obtida estudando-se a relação entre duas revisões opostas, em que algumas propriedades de simetria e justiça podem ser requeridas e definidas, em uma maneira "transacional" ao modo de Dewey. Quando essas propriedades não são satisfeitas, será verdadeiro para sempre que nós estamos e seremos encarregados de requerer uma revisão da situação. Mas, então, o centro do pragmatismo é a revolta contra o que é injusto, um conteúdo negativo. Ao contrário, Dewey sempre insistiu sobre o efeito positivo das situações negativas, enxergando o erro como aprendizado e a negação como determinação positiva.Palavras-chave: pragmatismo, Dewey, inquirição, revisão, ética, democracia, transação.

Apparue il y a une dizaine d’années dans le vocabulaire des relations internationales, la « diplomatie scientifique » reste mal connue, une erreur fréquente étant de la confondre avec la coopération scientifique internationale. Prenant appui sur des exemples puisés dans l’histoire et dans l’actualité des relations internationales, ce texte peut être lu comme une introduction générale à la diplomatie scientifique. Celle-ci appartient au champ des politiques publiques et recouvre des pratiques variées, identifiées à partir des grands objectifs poursuivis par les (...) États qui s’y engagent : attirer, coopérer, influencer. (shrink)

In this article, I argue that distinguishing ‘evolutionary’ from ‘Darwinian’ medicine will help us assess the variety of roles that evolutionary explanations can play in a number of medical contexts. Because the boundaries of evolutionary and Darwinian medicine overlap to some extent, however, they are best described as distinct ‘research traditions’ rather than as competing paradigms. But while evolu- tionary medicine does not stand out as a new scientific field of its own, Darwinian medicine is united by a number of (...) distinctive theoretical and methodological claims. For example, evolutionary medicine and Darwinian medicine can be distinguished with respect to the styles of evolutionary explanations they employ. While the former primarily involves ‘forward looking’ explanations, the latter depends mostly on ‘backward looking’ explanations. A forward looking explanation tries to predict the effects of ongoing evolutionary processes on human health and disease in contem- porary environments (e.g., hospitals). In contrast, a backward looking explanation typically applies evolutionary principles from the vantage point of humans’ distant biological past in order to assess present states of health and disease. Both approaches, however, are concerned with the prevention and control of human diseases. In con- clusion, I raise some concerns about the claim that ‘nothing in medicine makes sense except in the light of evolution’. (shrink)

Expliquant le social par le social, le sociologie se trouve prise dans le raisonnement naturel et en même temps confrontée à l'expression littéraire. Cela ne gêne pas l'anthropologue contemporain qui puise dans le roman d'initiation les ressources narratives nécessaires à la maîtrise de sa relation à l'Autre, toujours plus proche et plus intériorisé. Les découvertes de l'acuité philosophique et sociologique de la « Recherche » de Marcel Proust stimulent par ailleurs la réflexion sur les liens convergents, divergents ou ambivalents entre (...) la fiction romanesque et les sciences sociales. L'analyse de la genèse et de la transformation de ces liens est décidément encore en chantier. (shrink)
