Le Politique est généralement conçu comme un dialogue décousu et manquant d'unité, au mieux comme une succession de méthodes et de voies de recherche différentes (division dichotomique, mythe, paradigme) visant chacune à définir le politique. Le présent article vise au contraire à montrer que l'unité du dialogue est coextensive au développement d'une unique diaíresis, et ce en soulignant, à partir de ce que le texte dit lui-même, que le mythe, la méthode par paradigme et l'analyse des constitutions existantes ne sont (...) que des moyens permettant à la division de tracer le sentier qui mène au politique tel qu'il devrait être. L'ensemble des passages méthodologiques du dialogue permet ainsi d'expliquer comment le Politique explore les possibilités et souligne les limites de la méthode diairétique. Plato's Statesman is usually read as a tedious and carelessly written exercise in dialectic, or, more charitably, as a patchwork of loosely connected applications of different methods of definition of statesmanship (division, myth and paradigm). In this paper, I argue that this much disputed problem of the unity of the dialogue can be solved, provided one reads the whole dialogue as what it claims to be, i.e. the developpment of a single diaíresis. It can be shown that the Eleatic Visitor makes use of the myth, of the analysis of paradigms and of the treatment of non-ideal constitutions as means to following a single path, throughout the whole dialogue, that leads to the definition of statesmanship as it should be. The Statesman emerges as Plato's most profound reflection on the possibilities and the limits of the diairetic method. (shrink)

Même si bon nombre de ses travaux ont porté sur l’interprétation des mythes grecs fondateurs, Vernant a consacré la première partie de sa carrière à l’étude de la naissance de la polis et de la démocratie grecques. Contre l’idée d’un surgissement miraculeux de la Raison en Ionie au VI e siècle avant notre ère, Vernant a montré ce que la conception grecque de la rationalité hérite du monde homérique mais surtout ce qu’elle doit aux structures sociales et politiques de la (...) polis démocratique. Mais les travaux de Vernant font plus qu’établir l’acte de naissance d’une forme particulière de rationalité « fille de la cité » : ils touchent au cœur du problème plus général des rapports entre raison et démocratie.

Some interpretations of quantum mechanics regard a mixed quantum state as a ensemble, each individual member of which has a definite but unknown state vector. Other interpretations ascribe a state vector only to anensemble of similarly prepared systems, but not to anindividual. Previous attempts to detect the hypothetical individual state vectors have failed, essentially because the state operator enters the relevant equations linearly. An example from nonlinear dynamics, in which a density matrix enters nonlinearly, is examined because it might appear (...) to circumvent this difficulty. However, it is shown that the hypothetical individual state vectors can not be detected this way, so the adequacy of theensemble interpretation survives a critical test. (shrink)

A version of scattering theory that was developed many years ago to treat nuclear scattering processes, has provided a powerful tool to study universality in scattering processes involving open quantum systems with underlying classically chaotic dynamics. Recently, it has been used to make random matrix theory predictions concerning the statistical properties of scattering resonances in mesoscopic electron waveguides and electromagnetic waveguides. We provide a simple derivation of this scattering theory and we compare its predictions to those obtained from an exactly (...) solvable scattering model; and we use it to study the scattering of a particle wave from a random potential. This method may prove useful in distinguishing the effects of chaos from the effects of disorder in real scattering processes. (shrink)

This article examines constructivism, a paradigm in qualitative research that has been propagated by Egon Guba, Yvonna Lincoln, and Norman Denzin. A distinction is made between whether the basic presuppositions of constructivism are credible compared to those of a competing paradigm and whether constructivism's beliefs are internally consistent. The latter approach, i.e. whether constructivism is internally consistent, is the focus of this article. The issues singled out for discussion are concerned with the constructivist ontology and epistemology. This article shows that (...) constructivism's paradigmatic beliefs are internally in tension.

This paper recasts the normative shape of Fear and Trembling by presenting an ‘ethical reading’ based on an ethic of care. It will be argued that Abraham's response represents a commitment to sustain and deepen his fundamental relationship with God, to make absolute his relation to the Absolute. Since most readers tend to focus myopically on ‘the trial’ itself, apart from the context and history of the God-relationship, the proffered interpretations tend inevitably to distort the nature and significance of Abraham's (...) form of life. By remembering the pattern of attachment between God and Abraham, I think that a different normative picture will emerge, one which can be expressed in the grammar of care. (shrink)

Erasmus wrote his Colloquies as educational material for training boys in Latin conversation. This volume of the Amsterdam edition of the Latin texts of Erasmus offers a critical edition of the Latin texts of these influential, creative writings, which resemble short Latin plays.
