The species concept is one of the oldest and most fundamental in biology. And yet it is almost universally conceded that no satisfactory definition of what constitutes a species has ever been proposed. The present article is devoted to an attempt to review the status of the problem from a methodological point of view. Since the species is one of the many taxonomic categories, the question of the nature of these categories in general needs to be entered into.

Les progrès fulgurants des biotechnologies, combinés à la révolution des technologies de l'information, laissent entrevoir un avenir radicalement différent pour l'humanité. L'homme cybernétique, le "transhumain", peut-il vraiment "sauver l'homme" ou doit-il susciter nos craintes? A travers la critique de l'argumentaire transhumaniste, qui est fondé sur une conception appauvrie de ce qui fait l'humain, Thierry Magnin nous invite à porter un nouveau regard sur notre humble condition. Qu'est-ce que l'homme à l'heure où l'on pourra bientôt remplacer tous ses organes par des (...) machines intelligentes, voire transférer son psychisme? L'anthropologie chrétienne peut-elle nous aider à aborder avec confiance la révolution annoncée afin que celle-ci nous ouvre, non à un abandon de l'humain, mais à son plein accomplissement? (shrink)

The present thesis considers, in the light of Heisenberg's interpretation of the uncertainty formulas, the conditions necessary for the derivation of the quantitative statement or law of momentum conservation. The result of such considerations is a contradiction between the formalism of quantum physics and the asserted consequences of Heisenberg's interpretation. This contradiction decides against Heisenberg's interpretation of the uncertainty formulas on upholding that the formalism of quantum physics is both consistent and complete, at least insofar as the statement of momentum (...) conservation can be proved within this formalism. A few comments are also included on Bohr's “complementarity interpretation” of the formalism of quantum physics. A suggestion, based on a statistical mode of empirical testing of the “uncertainty” formulas, does not give rise to any such contradiction. (shrink)

The aim of this paper is on the one hand to remind the Western reader of some aporias of Chinese antiquity, and on the other hand to show that a logic of sorts or of types similar to that which has been proposed to explain the relation between categories (in the mathematical sense of the term) and logic brings much light on these aporias. This should be contrasted with older traditional explanations using conventional syllogistics or feeling satised with too simple (...) explanations such as the confusion between inclusion and identity. The article is based on preceding papers of the Author, but stresses the basic unity of the solutions which were proposed there. (shrink)

This is a critique of Michael Wolff's ideas on Kant and Aristotle. I criticize in particular his overestimation of Kant as a logician and his claim that Aristotle wants to offer proofs for his perfect syllogisms.

For over a decade, the world has experienced an accelerating erosion of a language that took hundreds of years to emerge. It is a language ordering time and space with words, such as enlightenment, reason, rationality, modernization, and the most recent by-word, globalization. However, it is a language that has been accompanied by colonialism, imperialism, racism, the exploitation of people and nature, an unequal distribution of the world's resources, pogroms, genocides, and world wars. There has been a gap between assumptions (...) underlying a visionary ambition and the often-brutal practices that have accompanied it. Moreover, it is a language that expresses European values, with the implicit or explicit suggestion that they pertain to the whole world, a civilizing mission from a European centre. Although the established narrative argued that there was continuous progress, it was a conclusion reached through hindsight. The idea of progress had to be repeatedly recreated through new visionary projects that attempted to live up to the high ideals their predecessors failed to achieve. Against the backdrop of this meta normative point of departure, the book argues that that a convincing grand narrative has failed to materialize since the discrediting of globalization. In the search for a new narrative, it argues at a meta normative level for a reformulation of the term 'global' away from its close connection to the globe as an unbounded self-propelling market that exists beyond human influence. 'Global' should no longer be reduced to auto-playing market fiction but instead be connected to the planet, Terra, the Earth. With reference to Latour and Chakrabarty, 'global' and 'planetary' mean cohabitation; life on earth seen as an infinite symbiotic system, nurtured, and protected, but also destroyed, by human action. The book argues that a new conceptualization of 'the global' and 'the planet' requires input from African and Asian language cultures. The book explores in depth the history of the two political key African concepts of ujamaa and ubuntu and argues that they are cases showing how work on a new global/planetary narrative might look. The investigation of the two concepts demonstrate that translations are juxtapositions that point up what is shared and what isn't between concepts in two or more languages. The point of comparison is not to develop a uniform, global perspective, even if that were possible, but to develop a global understanding of difference and, through that, to begin to look for a common ground. Translations of political key concepts are the source of a growing understanding of difference. (shrink)

In propounding his unified logico-linguistic theory W. S. Cooper [4] maintains that “...meaning... is so surrounded by unresolved debates and controversial distinctions that the modem investigator is sometimes well advised to dissociate himself from all precedent and define his terms afresh”. This is the line that will be adopted for this presentation carried out within the framework of Glottodidactics [5] and [10], i.e. in terms of this language-teaching discipline’s purposes as different from those of linguistics and, therefore, offering, hopefully, a (...) new angle of approach to the problem of meaning.
