We study function fields over p-adically closed fields in the first-order language of fields. Using ideas of Duret [D], we show that the field of constants is definable, and that the genus is an elementary property.

We study first-order properties of the quotient rings C(V)/P by a prime ideal P, where C(V) is the ring of p-adic valued continuous definable functions on some affine p-adic variety V. We show that they are integrally closed Henselian local rings, with a p-adically closed residue field and field of fractions, and they are not valuation rings in general but always satisfy ∀ x, y(x|y 2 ∨ y|x 2 ).

We consider valued fields with a distinguished isometry or contractive derivation as valued modules over the Ore ring of difference operators. Under certain assumptions on the residue field, we prove quantifier elimination first in the pure module language, then in that language augmented with a chain of additive subgroups, and finally in a two-sorted language with a valuation map. We apply quantifier elimination to prove that these structures do not have the independence property.

Probabilistic models have much to offer to philosophy. We continually receive information from a variety of sources: from our senses, from witnesses, from scientific instruments. When considering whether we should believe this information, we assess whether the sources are independent, how reliable they are, and how plausible and coherent the information is. Bovens and Hartmann provide a systematic Bayesian account of these features of reasoning. Simple Bayesian Networks allow us to model alternative assumptions about the nature of the information sources. (...) Measurement of the coherence of information is a controversial matter: arguably, the more coherent a set of information is, the more confident we may be that its content is true, other things being equal. The authors offer a new treatment of coherence which respects this claim and shows its relevance to scientific theory choice. Bovens and Hartmann apply this methodology to a wide range of much discussed issues regarding evidence, testimony, scientific theories, and voting. Bayesian Epistemology is an essential tool for anyone working on probabilistic methods in philosophy, and has broad implications for many other disciplines. (shrink)

L'oeuvre du philosophe anglais est au coeur du débat qui divise historiens et philosophes sur le thème de la sécularisation de la pensée politique moderne. Cet ouvrage ambitionne de contribuer nettement à ce débat, en montrant le rôle joué par la théologie de la toute-puissance dans la constitution de la philosophie morale et politique de Hobbes.

Les etudes ici reunies rendent compte de ce que furent le contexte historique et litteraire de la redaction des dialogues platoniciens, puis de la maniere dont leur auteur a choisi de confronter sa philosophie a la mythologie, afin de mener une enquete sur le monde, l'ame et la cite. Ces lectures veulent prendre ainsi la mesure de ce qui nous eloigne aujourd'hui de Platon, mais suggerer encore qu'une histoire de la philosophie qui cherche a s'affranchir de l'anachronisme trace un chemin (...) vers la philosophie.

What happens when the meaning of life based on a divine revelation no longer makes sense? Does the quest for transcendence end in the pursuit of material success and self-absorption? Luc Ferry argues that modernity and the emergence of secular humanism in Europe since the eighteenth century have not killed the search for meaning and the sacred, or even the idea of God, but rather have transformed both through a dual process: the humanization of the divine and the divinization of (...) the human. Ferry sees evidence for the first of these in the Catholic Church's attempts to counter the growing rejection of dogmatism and to translate the religious tradition into contemporary language. The second he traces to the birth of modern love and humanitarianism, both of which demand a concern for others and even self-sacrifice in defense of values that transcend life itself. Ferry concludes with a powerful statement in favor of what he calls "transcendental humanism"--a concept that for the first time in human history gives us access to a genuine spirituality rooted in human beings instead of the divine.

As the need for more diversity in business ethics is becoming more pressing in our global world, we provide an historical study of a Fair Trade (FT) movement, born in rural Mexico. We first focus on the basic assumptions of its founders, which include a worker–priest, Frans van der Hoff, a group of native Indians and local farmers who formed a cooperative, and an NGO, Max Havelaar. We then review both the originalities and challenges of the FT movement and its (...) potential contributions to the current theories and practices in business ethics. (shrink)

This article presents the results of an evaluative research on the impacts of collaborative research in the evolution of the practices of researchers and associated teachers. It was a question of understanding how the collaborative approach was useful and relevant to the participants, how it enabled them to better take ownership of their role as an associate teacher, and how to transform their practices.

One of the strongest strands in Nancy's philosophy is an attempt to rethink community and the very idea of the social in a way that does not ground these ideas in some individual subject or subjectivity. The fundamental argument of this book is that being is always 'being with', that 'I' is not prior to 'we', that existence is essentially co-existence. He thinks this being together, not as a comfortable enclosure in a pre-existing group, but as a mutual abandonment and (...) exposure to each other, one that would preserve the 'I' and its freedom in a mode of imagining community as neither a 'society of spectacle' nor via some form of 'authenticity'.

Distant Suffering examines the moral and political implications for a spectator of the distant suffering of others as presented through the media. What are the morally acceptable responses to the sight of suffering on television, for example, when the viewer cannot act directly to affect the circumstances in which the suffering takes place? Luc Boltanski argues that spectators can actively involve themselves and others by speaking about what they have seen and how they were affected by it. Developing ideas in (...) Adam Smith's moral theory, he examines three rhetorical 'topics' available for the expression of the spectator's response to suffering: the topics of denunciation and of sentiment and the aesthetic topic. The book concludes with a discussion of a 'crisis of pity' in relation to modern forms of humanitarianism. A possible way out of this crisis is suggested which involves an emphasis and focus on present suffering. (shrink)

A coherent story is a story that fits together well. This notion plays a central role in the coherence theory of justification and has been proposed as a criterion for scientific theory choice. Many attempts have been made to give a probabilistic account of this notion. A proper account of coherence must not start from some partial intuitions, but should pay attention to the role that this notion is supposed to play within a particular context. Coherence is a property of (...) an information set that boosts our confidence that its content is true ceteris paribus when we receive information from independent and partially reliable sources. We construct a measure cr that relies on hypothetical sources with certain idealized characteristics. A maximally coherent information set, i.e. a set with equivalent propositions, affords a maximal confidence boost. cr is the ratio of the actual confidence boost over the confidence boost that we would have received, had the information been presented in the form of maximally coherent information, ceteris paribus. This measure is functionally dependent on the degree of reliability r of the sources. We use cr to construct a coherence quasi-ordering over information sets S and S’: S is no less coherent than S’ just in case c_r is not smaller than c_r for any value of the reliability parameter. We show that, on our account, the coherence of the story about the world gives us a reason to believe that the story is true and that the coherence of a scientific theory, construed as a set of models, is a proper criterion for theory choice.

"Par dizaines, des expressions issues de la mythologie grecque se sont inscrites dans le langage courant : une "pomme de discorde", un "dédale de rues", prendre le "taureau par les cornes", toucher le "pactole", "tomber de Charybde en Scylla", suivre un "fil d'Ariane", "jouer les Cassandre", etc. Mille références endormies aux Sirènes, à Typhon, Océan, Triton, Python, Sibylle, Stentor, Mentor, Laïus, Argus, OEdipe et à tant d'autres personnages mythiques habitent encore incognito nos conversations de tous les jours. Je vous propose (...) de les réveiller en racontant les histoires magnifiques qui en sont l'origine. Mais il y a plus. Les grands mythes ne se limitent pas à des "contes et légendes". Ils proposent des leçons de vie et de sagesse d'une profondeur abyssale. La mythologie représente ainsi une tentative grandiose pour apporter des réponses à l'antique question métaphysique de "la vie bonne pour les mortels". Son étude, passionnante en elle-même, constitue pour cette raison une excellente introduction à la philosophie." Luc Ferry. (shrink)

"Ne croyez surtout pas qu'il s'agisse de science-fiction : 18 avril 2015, une équipe de généticiens chinois entreprenait d'"améliorer" le génome de quatre-vingt-trois embryons humains.

Sera-t-il possible un jour (bientôt? déjà?) d'"augmenter" à volonté tel ou tel trait de caractère de ses enfants, d'éradiquer dans l'embryon les maladies génétiques, voire d'enrayer la vieillesse et la mort en façonnant une nouvelle espèce d'humains "augmentés"?

Les progrès des technosciences sont d'une rapidité inimaginable, ils échappent encore à toute régulation. En parallèle, cette "infrastructure du monde" qu'est le Web a permis l'apparition d'une économie dite "collaborative", celle que symbolisent des applications comme Uber, Airbnb ou BlaBlaCar. Selon l'idéologue Jeremy Rifkin, elles annoncent la fin du capitalisme au profit d'un monde de gratuité et de souci de l'autre. N'est-ce pas, tout à l'inverse, vers un hyperlibéralisme, vénal et dérégulateur, que nous nous dirigeons? Certaines perspectives ouvertes par les innovations technoscientifiques sont enthousiasmantes, d'autres effrayantes.

Along with Husserl's Ideas and Heidegger's Being and Time, Being Given is one of the classic works of phenomenology in the twentieth century. Through readings of Kant, Husserl, Heidegger, Derrida, and twentieth-century French phenomenology (e.g., Merleau-Ponty, Levinas, and Henry), it ventures a bold and decisive reappraisal of phenomenology and its possibilities. Its author's most original work to date, the book pushes phenomenology to its limits in an attempt to redefine and recover the phenomenological ideal, which the author argues has never (...) been realized in any of the historical phenomenologies. Against Husserl's reduction to consciousness and Heidegger's reduction to Dasein, the author proposes a third reduction to givenness, wherein phenomena appear unconditionally and show themselves from themselves at their own initiative. Being Given is the clearest, most systematic response to questions that have occupied its author for the better part of two decades. The book articulates a powerful set of concepts that should provoke new research in philosophy, religion, and art, as well as at the intersection of these disciplines. Some of the significant issues it treats include the phenomenological definition of the phenomenon, the redefinition of the gift in terms not of economy but of givenness, the nature of saturated phenomena, and the question “Who comes after the subject?” Throughout his consideration of these issues, the author carefully notes their significance for the increasingly popular fields of religious studies and philosophy of religion. Being Given is therefore indispensable reading for anyone interested in the question of the relation between the phenomenological and the theological in Marion and emergent French phenomenology.

This study explains how the myths of Greece and Rome were transmitted from antiquity to the Renaissance. Luc Brisson argues that philosophy was ironically responsible for saving myth from historical annihilation. Although philosophy was initially critical of myth because it could not be declared true or false and because it was inferior to argumentation, mythology was progressively reincorporated into philosophy through allegorical exegesis. Brisson shows to what degree allegory was employed among philosophers and how it enabled myth to take on (...) a number of different interpretive systems throughout the centuries: moral, physical, psychological, political, and even metaphysical. How Philosophers Saved Myths also describes how, during the first years of the modern era, allegory followed a more religious path, which was to assume a larger role in Neoplatonism. Ultimately, Brisson explains how this embrace of myth was carried forward by Byzantine thinkers and artists throughout the Middle Ages and Renaissance after the triumph of Chistianity, Brisson argues, myths no longer had to agree with just history and philosophy but the dogmas of the Church as well.

Critical evaluations of the current movement of corporate social responsibility commodification have neglected an important question: How do CSR professionals manage the tensions resulting from the search for both profit and social responsibility? This article addresses this question by analyzing the discourse of CSR consultants with the aim of understanding how they deal with such tensions through identity work. Our findings suggest that people who claim, or who are ascribed, paradoxical professional identities may engage in ‘paradoxical identity mitigation’ – a (...) process whereby the concomitant and paradoxical use of linguistic strategies is aimed at simultaneously embracing and distancing oneself from contradictory identity demands. In uncovering how CSR professionals discursively manage the tensions engendered by CSR commodification, our results also advance current knowledge of CSR by shedding light on the underlying processes whereby new ‘hybrid’ identities are constituted and mobilized by actors to make sense of their professional activities.

This paper addresses a problem for theories of epistemic democracy. In a decision on a complex issue which can be decomposed into several parts, a collective can use different voting procedures: Either its members vote on each sub-question and the answers that gain majority support are used as premises for the conclusion on the main issue, or the vote is conducted on the main issue itself. The two procedures can lead to different results. We investigate which of these procedures is (...) better as a truth-tracker, assuming that there exists a true answer to be reached. On the basis of the Condorcet jury theorem, we show that the pbp is universally superior if the objective is to reach truth for the right reasons. If one instead is after truth for whatever reasons, right or wrong, there will be cases in which the cbp is more reliable, even though, for the most part, the pbp still is to be preferred. (shrink)

In their recently published book Nudge (2008) Richard H. Thaler and Cass R. Sunstein (T&S) defend a position labelled as ‘libertarian paternalism’. Their thinking appeals to both the right and the left of the political spectrum, as evidenced by the bedfellows they keep on either side of the Atlantic. In the US, they have advised Barack Obama, while, in the UK, they were welcomed with open arms by the David Cameron's camp (Chakrabortty 2008). I will consider the following questions. What (...) is Nudge? How is it different from social advertisement? Does Nudge induce genuine preference change? Does Nudge build moral character? Is there a moral difference between the use of Nudge as opposed to subliminal images to reach policy objectives? And what are the moral constraints on Nudge? (shrink)

A vital and underappreciated dimension of social interaction is the way individuals justify their actions to others, instinctively drawing on their experience to appeal to principles they hope will command respect. Individuals, however, often misread situations, and many disagreements can be explained by people appealing, knowingly and unknowingly, to different principles. On Justification is the first English translation of Luc Boltanski and Laurent Thévenot's ambitious theoretical examination of these phenomena, a book that has already had a huge impact on French (...) sociology and is likely to have a similar influence in the English-speaking world. In this foundational work of post-Bourdieu sociology, the authors examine a wide range of situations where people justify their actions. The authors argue that justifications fall into six main logics exemplified by six authors: civic (Rousseau), market (Adam Smith), industrial (Saint-Simon), domestic (Bossuet), inspiration (Augustine), and fame (Hobbes). The authors show how these justifications conflict, as people compete to legitimize their views of a situation. On Justification is likely to spark important debates across the social sciences.

The word myth is commonly thought to mean a fictional story, but few know that Plato was the first to use the term muthos in that sense. He also used muthos to describe the practice of making and telling stories, the oral transmission of all that a community keeps in its collective memory. In the first part of Plato the Myth Maker , Luc Brisson reconstructs Plato's multifaceted description of muthos in light of the latter's Atlantis story. The second part (...) of the book contrasts this sense of myth with another form of speech that Plato believed was far superior: the logos of philosophy. Gerard Naddaf's substantial introduction shows the originality and importance both of Brisson's method and of Plato's analysis and places it in the context of contemporary debates over the origin and evolution of the oral tradition. "[Brisson] contrasts muthos with the logos found at the heart of the philosophical reading. [He] does an excellent job of analyzing Plato's use of the two speech forms, and the translator's introduction does considerable service in setting the tone."-- Library Journal. (shrink)

In the third book in the trilogy that includes Reduction and Givenness and Being Given. Marion renews his argument for a phenomenology of givenness, with penetrating analyses of the phenomena of event, idol, flesh, and icon. Turning explicitly to hermeneutical dimensions of the debate, Marion masterfully draws together issues emerging from his close reading of Descartes and Pascal, Husserl and Heidegger, Levinas and Henry. Concluding with a revised version of his response to Derrida, In the Name: How to Avoid Speaking (...) of It, Marion powerfully re-articulates the theological possibilities of phenomenology.

The coherentist theory of justification provides a response to the sceptical challenge: even though the independent processes by which we gather information about the world may be of dubious quality, the internal coherence of the information provides the justification for our empirical beliefs. This central canon of the coherence theory of justification is tested within the framework of Bayesian networks, which is a theory of probabilistic reasoning in artificial intelligence. We interpret the independence of the information gathering processes (IGPs) in (...) terms of conditional independences, construct a minimal sufficient condition for a coherence ranking of information sets and assess whether the confidence boost that results from receiving information through independent IGPs is indeed a positive function of the coherence of the information set. There are multiple interpretations of what constitute IGPs of dubious quality. Do we know our IGPs to be no better than randomization processes? Or, do we know them to be better than randomization processes but not quite fully reliable, and if so, what is the nature of this lack of full reliability? Or, do we not know whether they are fully reliable or not? Within the latter interpretation, does learning something about the quality of some IGPs teach us anything about the quality of the other IGPs? The Bayesian-network models demonstrate that the success of the coherentist canon is contingent on what interpretation one endorses of the claim that our IGPs are of dubious quality. (shrink)

Hope obeys Aristotle's doctrine of the mean: one should neither hope too much, nor too little. But what determines what constitutes too much and what constitutes too little for a particular person at a particular time? The sceptic presents an argument to the effect that it is never rational to hope. An attempt to answer the sceptic leads us in different directions. Decision-theoretic and preference-theoretic arguments support the instrumental value of hope. An investigation into the nature of hope permits us (...) to assess the intrinsic value of hope. However, it must be granted to the sceptic that there is a tension between hope and epistemic rationality. I conclude with some reflections about the relationship between hope and character features that are constitutive of inner strength. (shrink)

We present an age-structured model for erythropoiesis in which the mortality of mature cells is described empirically by a physiologically realistic probability distribution of survival times. Under some assumptions, the model can be transformed into a system of delay differential equations with both constant and distributed delays. The stability of the equilibrium of this system and possible Hopf bifurcations are described for a number of probability distributions. Physiological motivation and interpretation of our results are provided.

If we receive information from multiple independent and partially reliable information sources, then whether we are justified to believe these information items is affected by how reliable the sources are, by how well the information coheres with our background beliefs and by how internally coherent the information is. We consider the following question. Is coherence a separable determinant of our degree of belief, i.e. is it the case that the more coherent the new information is, the more justified we are (...) in believing the new information, ceteris paribus? We show that if we consider sets of information items of any size (Holism), and if we assume that there exists a coherence Ordering over such sets and that coherence is a function of the probability distribution over the propositions in such sets (Probabilism), then Separability fails to hold.
