We discuss the finite-to-one Rudin-Keisler ordering of ultrafilters on the natural numbers, which we baptize the Rudin-Blass ordering in honour of Professor Andreas Blass who worked extensively in the area. We develop and summarize many of its properties in relation to its bounding and dominating numbers, directedness, and provide applications to continuum theory. In particular, we prove in ZFC alone that there exists an ultrafilter with no Q-point below in the Rudin-Blass ordering.

Le travail présenté dans cet article s’inscrit dans une recherche qui a pour but la constitution d’un corpus scolaire et le développement d’un outil d’aide à son exploitation à partir de l’annotation de phénomènes linguistiques saillants. Nous nous concentrerons ici sur les écrits produits en fin de classe de CP par des scripteurs encore débutants. L’objet de ce travail est d’explorer les possibilités qu’offre le traitement automatique des langues pour appréhender ces écrits particulièrement éloignés de la norme. L’hypothèse est que (...) la connaissance du contexte de production facilite ce processus. Nous mesurons cet apport au travers d’un exemple de traitement, à savoir le développement d’un outil d’aide à l’annotation de certaines erreurs orthographiques. Après une rapide présentation du projet et des caractéristiques du corpus élaboré, l’article propose un exposé détaillé du module d’annotation de ces erreurs. Il en expose la méthode d’identification et de correction au moyen d’une ressource lexicale de formes phonologiques ainsi que le modèle d’annotation élaboré. (shrink)

Le livre de Jean-Claude Terrier aborde l'histoire de la philosophie moderne, de Kant à Heidegger, sous l'angle de la question du corps et du désir, chemin buissonnier peu emprunté par les exégètes des grands systèmes totalitaires de la pensée - systèmes dont le souci essentiel fut de délimiter le champ théorique du savoir, ce qu'on désigne comme la critique de la connaissance. Prenant appui sur d'autres sources, tout particulièrement patristiques, Jean-Claude Terrier conteste l'ambition totalitaire des philosophies issues de (...) l'idéalisme allemand du XIXe siècle. En introduisant le thème du corps et du désir, propre à la tradition théologique et spirituelle du christianisme, il élargit l'horizon de la réflexion hégélienne et marxiste, il en marque les insuffisances et engage à son tour la voie de la pensée non vers la théorie de la totalité mais, par-delà la proclamation nietzschéenne de la mort de Dieu, vers l'expérience intérieure de la plénitude. Nous avons ici, d'une écriture puissante et transparente, le récit des aventures de la dialectique et l'ouverture d'une pensée en quête de la réconciliation de la chair et de l'esprit dans la transcendance de l'amour.

Dans les premières lignes du compte-rendu substantiel qu’il fournit de l’ouvrage de Mikel Dufrenne paru en 1963 sous le titre Le Poétique, Paul Ricœur écrit : Le dernier livre de Mikel Dufrenne n’est pas seulement le fruit mûr d’une œuvre qui pousse comme une plante – les images végétales conviennent à merveille à une philosophie qui se veut fidèle aux voix de la Nature! –, il est aussi l’un des signes de la mue de la philosophie française : celle-ci, de (...) multiples façons, se rebelle comme l...

The implementation of a diplomacy that could put more emphasis on democracy and human rights was not an easy process in Belgium. Treatment of these matters have taken a different perspective in Zaïre, Rwanda and Burundi, Belgium 's three most important African partners. Reasons for that are twofold. Fore one thing, the Belgian foreign affairs service has always been overloaded by mercantile preoccupations. Secondly, knowledge on Africa has been limited to short circle diplomatic contacts while no instruments were ever implemented (...) that could have ensured some following up of the African civil society at large.In the future, the continuation for a slow process of disengagement might be foreseable. New "partners" might come to the forefront such as South Africa while the U.S. and international financial organisations will definitely try to impose "good governance" together with a reasonable dose of human rights.

In reviewing the Belgian policy towards Zaïre for the last two decades, one is struck by a certain politica! as well as economic withdrawal which has become more obvious since the end of the sixties. In the context of the «Mobutu Plan», the Marshall Plan for Zaïre, or in that of the two Shaba upheavals, Belgium, unlike France with respect to its former colonies, has choosen to align itself with big powers policies and international organizations, and to avoid taking too (...) strong stands in the rather confuse situation which prevails in Zaïre today. Although unanimity does no langer exist among the various Belgian pressures groups about what is tobe done in Zaïre, the official policy of the government is entrenched in a «wait and see» attitude which points to the deepening contradictions within Western states towards Africa in general and Zaïre in particular.

The descriptive “null” hypothesis is strengthened by the fact that during dreaming sleep stage, the primary visual cortex is deactivated as compared with other sleep stages.

A cellular automaton that is related to the "mosaic cycle concept" is considered. We explain why such automata sustain very often, but not always, n-periodic trajectories (n being the number of states of the automaton). Our work is a first step in the direction of a theory of these type of automata which might be useful in modeling mosaic successions.

This paper argues that the dominant mainstream neo‐classical economic theory propounds a world‐view which is based not simply on half‐truths, but on straight lies. This is particularly significant since the influence of the economic world‐view reaches into every realm of social thought. Although overtly grounded in utilitarianism, the basis of neo‐classical thought has undergone two shifts of meaning which have converted the original self‐evident utilitarian presuppositions into an ideology.The first of these alters the utilitarian proposition that ‘we seek satisfaction’ into (...) the statement that ‘we only seek satisfaction’. It follows that human action is motivated by nothing other than selfishness and greed, and that altruism therefore cannot exist: anything that looks like altruism is therefore nothing other than egoism in disguise, and there is no place for ethical reasoning in individual choice.The second shift alters the premise that our goal is ‘maximum satisfaction’ to the assertion that what we seek is ‘maximum monetary gain’. This shift is already present in the writings of Jeremy Bentham, and forms the basis of much subsequent work in economics. In particular, it has facilitated the emergence of what one might term ‘economic imperialism’, i.e. the use of economic theory to analyse social issues – family size, racial discrimination, marriage, education choices, among others. In all of these cases monetary gain is the paramount criterion. For business ethics the most obvious example here is the absolutisation of profit as the sole criterion of business achievements, and of salary as the sole criterion of work choice and worker satisfaction.Both of these premises are then used to demonstrate that it is free competition which will ensure maximum social welfare. This conclusion is both relativistic and reductionistic. In the first place, the necessary conditions for perfect competition can never exist. Nor can ‘optimum social welfare’ be translated into ‘optimum welfare for all’ in an economic world‐view which sees wealth and poverty as the ‘just deserts’ of hard work and laziness respectively.The dominant economic theory is thus explicitly immoral in that it enshrines the absolute sovereignity of the individual and the law of the jungle as social norms. The qualitative measure of human happiness is desire, the quantitative measure is money. From an ethical perspective we must reject the falsity of this world‐view. (shrink)

What does the ostensibly innocuous phrase “das Selbst” exactly mean in Heidegger’s fundamental ontology? Does Heidegger really have a “theory of the self ” in the same way as, say, Descartes, Locke or Husserl? This is what has been often concluded by many interpreters of Being and Time, and it is that view that the current paper attempts to challenge. Heidegger not only rejects the supposition of a substantial ego, along the lines of Descartes’ conception, but he also repudiates any (...) “self ” understood as a present-at-hand being, an inner core of Dasein, and he insists on the intrinsic connection between the “egologies,” from Descartes to Husserl, and “traditional ontology”. What seems to be at stake in the fundamental-ontological approach of Sebstheit and Selbstsein, Being-oneself, is rather a complete paradigm-shift, since both concepts refer to “ways of being” or “ways of existing” of Dasein, and no longer at all to a self-identical being of a condition of its self-identity. In trying to investigate the economy of the related existential concepts of Jemeinigkeit, Selbstheit and Man-selbst, this article makes the claim that Heidegger’s break with egology is much deeper that it has been often thought, and that the phenomenologist raises a completely new question, rather than trying to give a new response to older ones.

Algebraic theories for extensive measurement are traditionally framed in terms of a binary relation $\lesssim $ and a concatenation (x,y)→ xy. For situations in which the data is "noisy," it is proposed here to consider each expression $y\lesssim x$ as symbolizing an event in a probability space. Denoting P(x,y) the probability of such an event, two theories are discussed corresponding to the two representing relations: p(x,y)=F[m(x)-m(y)], p(x,y)=F[m(x)/m(y)] with m(xy)=m(x)+m(y). Axiomatic analyses are given, and representation theorems are proven in detail.

Cet article aborde la question générale du développement d'une histoire sociale des mathématiques et de la logique, à partir d'un cas historique. Il vise à rendre compte de certains traits de l'histoire récente de la logique floue. À cette fin, il met en oeuvre une sociologie des pratiques de démonstration et une approche fondée sur l'analyse matérielle du travail logique, notamment de l'activité d'écriture et de lecture. Il esquisse la construction d'une histoire sociale des formes de démonstration.

Essentiellement composé de photographies aériennes, Earthscape est néanmoins un ouvrage de phénoménologie. Après avoir commencé des études d’architecture, puis soutenu une thèse de doctorat en philosophie à Freiburg, son auteur, Chan-fai Cheung, qui a dirigé le département de philosophie de la Chinese University of Hong Kong, met en effet, en tant que photographe, en suspens nos appréhensions habituelles et, pour ainsi dire, naturelles de la terre ; comme l’écrit Bernhard Waldenfels à propos...

Por que o nome do um encanta? Não será porque, mesmo ao preço do mais cruel sofrimento, os homens têm nele a ilusão de guardarem sua própria nomeação e, ao mesmo tempo, permanecerem associados? La Boétie parece ensinar, assim, que os homens perdem a liberdade, mas não o desejo de se tornarem livres.

Les lignes 72-74 de la lex portorii Asiae découverte à Éphèse mentionnent, d'après les éditeurs H. Engelmann et D. Knibbe, les dîmes et la scriptura (impôt sur les pâturages), les premières pour en régler la perception, la seconde pour dispenser de droits de douane les troupeaux en transhumance d'été. Il s'agit en fait de fausses lectures : à la 1. 74, il faut lire (au lieu de μετακομιδηι τη ήλιαρίφ) : ή 8ι' αυτό. D'autre part il n'y a pas deux (...) phrases concernant deux sujets différents, mais une seule, à lire continûment. Ce sont les produits des dîmes qui, dans certaines circonstances, et à certaines conditions, sont dispensés de payer la douane. On suggère qu'il était question 1. 73, dans la lacune, des «droits de garde» (custodia, φυλακείον) dans les entrepôts de la douane. (shrink)
