We propose a new derivation of Wigner's function based on the property of positivity of its integrals along straight lines in phase space. Identifying the values of these marginalizations with densities pertaining to invariant observables, we are able to reconstruct Wigner's pseudo-distribution from its slices.

`Mr Russell's very brilliant criticism of Leibniz ... is a piece of controversial philosophy as well as a contribution to history.' - Bernard Bosanquet.

The objective of this article is to contribute to the epistemological, theoretical, methodological, and pedagogical debates concerning the relationship between research activities, training activities, and work activities. Its main focus is on new forms of engineering, thought of as cooperative and transformative. After situating the issues of the reciprocal triadic relationships between the three poles, the article presents two practical cases of transformative cooperative engineering. The authors then return to their epistemological position, which is socio-constructivist, complex, interactionist, and critical. They (...) sketch out the first elements of an elaborate system of intelligibility (multi-referential and transdisciplinary) aimed at supporting the hypothesis of an engineering process of joint transformation (trades, actors, organizations, training provision). The article also presents the research methodology (training-action-research) developed. A discussion of the issues and conditions of possibility of cooperative and transformative engineering concludes the article. (shrink)

On connaît cette thèse de Bachelard : "Il n'y a pas de vérités premières, il n'y a que des erreurs premières." Cet intérêt très vif pour l'erreur remonte en fait au me siècle, lorsque les théories génétiques de l'esprit, d'une part, la méthodologie expérimentale et les approches probabilistes, d'autre part. lui confèrent un statut dont elle était auparavant privée. L'erreur funeste qui nous fait trébucher et nous détourne du vrai est remplacée par l'erreur instructive, censée nous renseigner sur les lois (...) fondamentales de l'esprit humain, la logique du ju2ement, la normativité du vivant. Le thème de l'erreur est mis au programme des lycées, comme une question qui recoupe logique et psychologie. Victor Brochard lui consacre sa thèse, qui fait apparaître les ambiguïtés de l'intellectualisme et du volontarisme. Si tant d'auteurs s'intéressent à ce thème - parmi lesquels Cournot, Duhem, Lagneau, Meyerson... -, c'est parce qu'il est le révélateur de toutes les grandes problématiques épistémologiques et gnoséologiques de la séquence historique ici envisagée, de sorte que c'est tout un pan de la philosophie française que l'on peut revisiter sous cet angle."--Page 4 of cover.

Clear and accessible, this little book is an intelligible and stimulating guide to those problems of philosophy which often mistakenly make the subject seem too lofty and abstruse for the lay mind.

Contents Include: Mysticism and Logic - The Place of Science in a Liberal Education - A Free Man's Worship - The Study of mathematics - Mathematics and the Metaphysicians - On Scientific Method in Philosophy - The Ultimate Constituents of Matter - The Relation of Sense-Data to Physics - On the Notion of Cause - Knowledge by Acquaintance and Knowledge by Description.

Only a handful of papers reprinted in this collection were written after 1959--Russell retired from academic philosophy for the second time after the publication of My Philosophical Development, devoting his final years to political protest. 1949 and 1950--the years that Russell was appointed to the Order of Merit and awarded the Nobel Prize for Literature--fall in the period covered by this volume. The papers include autobiographical and self-critical writings as well as papers on non-demonstrative inference, his contemporaries, metaphysics and epistemology, (...) ethics and politics, John Stuart Mill, religion, Albert Einstein, and ordinary language philosophy.
