Defeasible reasoning is concerned with the logics of non-deductive argument. As is described in the literature, the study of this type of reasoning is considerably more involved than the study of deductive argument, even so that, in realistic applications, there is often a lack of resources to perform an exhaustive analysis. It follows that, in a theory of defeasible reasoning, the order and direction in which arguments are developed, i.e. theprocedure, is important. The aim of this article is to show (...) that debate is the most efficient procedure to argue in the presence of limited resources. To do so, there is first some general theory on defeasible argumentation, which is followed by an introduction to the problem of dialectical search. The problem of dialectical search is (or at least, should be) the essential issue in every theory on argumentation, and emerges at every occasion that involves adjudication on competing arguments. Starting with an example, it is explained that dialectical search can be best scheduled according to classical debating techniques, that work along well-tried methods. These methods (which include various forms of curtailment, interruption, and interpretation) have proven their value in keeping debating efforts within reasonable bounds. How they apply in a theory of formal argument, will be shown in this article. (shrink)

(1) What may be gained by applying concepts generalised from economics to methodological problems? The perspective of cost-benefit analysis ('CBA' for short) may help the researcher to see what sorts of questions he should take into account when dealing with particular methodological problems. This claim is supported by applying generalised CBA-thinking to two standard problems of methodology. (2) In the practice of research the handling of basic statements does not normally constitute any problem, and no conscious decision is involved. In (...) the methodological reconstruction the key questions are: 'How can a particular basic statement be criticised?' and 'What are the costs of defending a statement that is "problematic"?' The problem of the empirical 'base' is an investment problem: whether or not to invest time and effort into processing a particular basic statement into a falsifying hypothesis for the theory we wish to test. The valuation of the costs of rejecting or, as the case may be, of defending a basic statement, are objective. (3) With respect to theories, in basic science, the issue is not one of acceptance or rejection of a single theory, but rather of theory preference. Both the rational response to a falsification and rational theory preference are governed by CBA-considerations. The option for one of two competing theories is based upon a CBA where the valuation of benefits and costs is objective. Theory change is an objective process, at least in those fields, where theorising is closely controlled by empirical testing: the better theory drives out the less good theory. The costs of defending a theory that is less good than its competitor are mainly epistemic resources forgone. The use of CBA in methodology not only is compatible with Popper's position, but it may pay to view Popper's methodology as an application of CBA to epistemic situations. (shrink)

Computational dialectics is concerned with the formal representation of argument and dispute. The field emerged from developments in philosophy, artificial intelligence and legal theory. Its goal is to suggestalgorithms, procedures and protocols to investigate the tenability of logical claims, on the basis of information in the form of rules and cases. Currently, the field slowlyconverges to the opinion that dispute is the most fair and effective way to investigate claims. The basic assumption of this field is that dispute is the (...) most fair and effective way to investigate claims. The definition of a formal dispute varies throughout the literature, butis considered not to vary within one and the same logical system. In this paper it is shown that parts of the definition of a dispute may change within one logical system.To this end, the notion of partial protocol specification (PPS) is introduced. A PPS is a part of the definition of the protocol. A modification to the protocol, in the form of a PPS, can be put forward, disputed, established and incorporated as aneffective `point of order. The paper demonstrates the existence of self-undermining PPSs, it discusses the relevance of PPSs for dialectical models of legal argument and concludes with a description of how PPSs can be built into existing argumentation systems.

‘Gender ideology’ is a term used by many, but especially the Vatican, to chastise the view that sexual difference is more than just male and female, sexuality more than desire of the opposite. Each of the three books discussed in this article defends some version of this supposed ideology; each argues—though in different ways—for the need to move beyond a dimorphic account of sexual difference. Their arguments are taken up and deployed against what is here presented as the ideology of (...) sexual dimorphism, as it is seen in the body theology of John Paul II. It is argued that such a theology dehumanises intersexed people, along with homosexuals, and undermines Christian soteriology. The church needs to acknowledge as fully human all who don’t conform to heterosexual dimorphism; it needs to embrace a ‘third sex’ without reserve. (shrink)

Avant 1968, un seul ouvrage, très critique, avait été consacré à Marcuse. Même les leaders du mouvement étudiant semblent tout ignorer de sa pensée. Pourtant, la parution de L’Homme unidimensionnel au plus fort des « événements », bien qu’elle soit une coïncidence, peut révéler l’existence d’une réception souterraine mais intense portée par au moins deux générations dans des cercles intellectuels et éditoriaux influents ainsi que dans le mouvement trotskiste.

In this paper I pursue two goals. Firstly, I try to evaluate how Susan Haack receives and categorically rejects Rorty's anti-epistemological message from Philosophy and the Mirror of the Nature and some subsequent writings. I reconstruct Haack's counterarguments and Rorty's responses to these counterarguments. Secondly, I propose to deconstruct the theoretical position from which Haack orchestrates her attack on Rorty. On the one hand I show that she assumes a series of classical metaphysical presuppositions that are difficult to accept today, (...) which predisposes her to a lack of hermeneutical flexibility and clarity. On the other hand, at least some of Haack's arguments against Rorty are erroneous. Following Michael Williams, I point out that Rorty's position in Mirror is not against knowledge, since it raises questions about the legitimacy of epistemology. The challenge of my approach is not to defend Rorty, but rather to examine the mechanism of a charge against him in the name of a pretended philosophical correctness. I call this type of charge “hermeneutics of annihilation”. Haack's hermeneutics of annihilation is a pseudo-hermeneutics, since her goal is not to understand the stake of Rorty's philosophy exposed in Mirror. She only understood, from the point of view of an epistemologist ideology, that this work would be a threat to Truth, Knowledge, Epistemology, Science, and Reason. (shrink)

The Church is a sexed body, in both carnal and symbolic terms. The Church has sex, but being the Church it does so in a radically creative way. This article explores the contrast between sex as imagined by the Church and as imagined by evolutionary psychology (Darwinism). It argues that the latter reduces sex to reproduction (repetition) and makes this a metaphysical principle, whereas the Church transforms sex into a means for final beatitude. (Christian sex is not about self-perpetuation, but (...) about welcoming strangers; not about children as possessions, but as God's most precious gifts.) Darwinism strangely repeats a debased (neoscholastic) form of the natural law, whereas the Church looks to follow a law that is the dispossessive desire of God for God. Sex after this law orders us towards the infinite joy of our consummation with and in God, in the fellowship of Christ and the holy saints. (shrink)

La philosophie juive doit être distinguée du judaïsme et de la pensée juive pour pouvoir être questionnée sur son caractère national. Son travail de pensée consiste à transcrire le figural de la pensée biblico-talmudique en concepts, à se mouvoir entre le propre, qu’elle n’est pas, et l’étranger, qu’elle arpente. Ni universelle, ni nationale, la philosophie juive, succession discontinue d’événements traductifs, permet de mieux comprendre comment chaque philosophie singulière est plus que le champ philosophique dans lequel elle s’inscrit.

This article assumes that the key element in Relativism is the denial of any comparability between different moral codes. Each system of morality is, according to the relativist, defined internally to any given culture, as parallels with examples in sport might illustrate, and as two key examples from recent moral disputes amply show. While classical writers such as Hume and Bentham, each in his way a kind of utilitarian, certainly intended to be absolutist, it might nevertheless be argued that they (...) left the way open to relativism despite their intentions. The absolutist needs to establish a common moral standard of some kind which can be used as a standard of comparison between apparently different moral codes. Hume's assumption that we share the disposition to sympathy with others seems far too optimistic; and Bentham's attempt to be scientific presupposes a shared view both of values and of the canons of moral reasoning; but there is arguably no such shared view. Might some version of Aristotelianism be a more promising approach? The article ends with an ariswer to this question. /// O presente artigo parte do pressuposto de que o elemento-chave do Relativismo é a negação de toda e qualquer comparabilidade entre diferentes códigos morais. Cada sistema de moralidade é, de acordo com o relativista, deftnido internamente nos termos de cada cultura determinada, tal como se pode ilustrar com exemplos do mundo do desporto, e dois exemplos tirados da discussão moral mais recente amplamente demonstram. Enquanto que escritores clássicos tais como David Hume e Jeremy Bentham, cada um deles utilitarista à sua maneira, pretendiam certamente ser absolutistas, a verdade é que, argumenta o autor do artigo, ambos deixaram, apesar das suas intenções, o caminho aberto ao relativismo. O absolutista necessita de alguma forma de estabelecer um padrão moral comum que possa ser usado como termo de comparação entre códigos morais aparentemente diferenciados. O pressuposto de Hume de que nós partilhamos uma inclinação para a simpatia em relação a outros seres humanos parece demasiado optimista; por seu lado, a tentativa de Bentham de corresponder às expectativas da ciência pressupõem, por seu lado, uma visdo comum dos valores e dos cânones do raciocínio moral. O problema, porém, é que se pode demonstrar não existir uma tal visão comum. Assim, pergunta o autor do artigo, não será de considerar uma certa versão do Aristotelismo como uma abordagem mais promissora? A resposta a esta questão constitui a parte final do artigo. (shrink)

The paper presents the results of two vignette studies that examine how company breastfeeding accommodation influences ratings of organizational attractiveness and work-related intentions. North American business students and employees engaged in long-term employment found organizations that accommodate breastfeeding to be more fair, attractive, and were more likely to apply to them, and accept jobs from them, than organizations that did not accommodate. Effects were stronger for female participants than for male participants. Female participants without children indicated lower support for breastfeeding (...) accommodation than female participants with children and male participants. (shrink)

Quand on compare l' Optique d'Ibn al-Haytham à celle de Ptolémée, on rencontre des innovations à coup sûr capitales, et qui chacune mériterait une analyse particulière: étude expérimentale de la propagation rectiligne de la lumière, nouvelle théorie de la vision fondée sur la réception dans l'œil de rayons lumineux, recherche du lien entre l'anatomie de 1'œil et sa fonction optique, preuve expérimentale que la réfraction joue un rôle important dans la vision, et j'en passe: les dimensions d'un article de revue (...) n'y suffiraient pas. Aussi bien mon but est-il plus global et plus synthétique. Il consiste à tenter de faire le point sur ce qu'est devenue, après Ibn al-Haytham, l'insertion de l'optique dans le système des savoirs qui lui sont connectès, en comparant cette insertion à ce qu'elle était au temps de Ptolémée, c'est-à-dire dans l'œuvre de référence reçae et travaillée par lui.

Fluid-phase endocytosis (pinocytosis) kinetics were studied inDictyostelium discoideum amoebae from the axenic strain Ax-2 that exhibits high rates of fluid-phase endocytosis when cultured in liquid nutrient media. Fluorescein-labelled dextran (FITC-dextran) was used as a marker in continuous uptake- and in pulse-chase exocytosis experiments. In the latter case, efflux of the marker was monitored on cells loaded for short periods of time and resuspended in marker-free medium. A multicompartmental model was developed which describes satisfactorily fluid-phase endocytosis kinetics. In particular, it accounts (...) correctly for the extended latency period before exocytosis in pulse-chase experiments and it suggests the existence of some sorts of maturation stages in the pathway.

This innovative publication maps out the broad and interdisciplinary field of contemporary European social theory. It covers sociological theory, the wider theoretical traditions in the social sciences including cultural and political theory, anthropological theory, social philosophy and social thought in the broadest sense of the term. The volume surveys the classical heritage, the major national traditions; the fate of social theory in a post-national and post-disciplinary era; identifies what is distinctive about European social theory. It is divided into five parts: (...) disciplinary traditions, national traditions, major schools, key themes, and the reception of European social theory in American and Asia. It is an indispensable book for students, teachers and researchers in sociology, cultural studies, politics, philosophy and human geography. (shrink)

Engageant une « idée de l’homme », la recherche en sciences sociales présuppose des réponses – presque toujours implicites – à des questions philosophiques comme « l’essence du moi », « la nature de l’esprit », « la possibilité de se connaître soi-même », « la relation entre l’esprit et le corps », « la possibilité de connaître d’autres esprits », etc. :..
