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)

We appeal to the theory of Bayesian Networks to model different strategies for obtaining confirmation for a hypothesis from experimental test results provided by less than fully reliable instruments. In particular, we consider (i) repeated measurements of a single test consequence of the hypothesis, (ii) measurements of multiple test consequences of the hypothesis, (iii) theoretical support for the reliability of the instrument, and (iv) calibration procedures. We evaluate these strategies on their relative merits under idealized conditions and show some surprising (...) repercussions on the variety-of-evidence thesis and the Duhem-Quine thesis. (shrink)

I provide a taxonomy of the various circumstances under which one might reasonably say "P and I will believe that not-P" or violate the Reflection Principle.

Belgium has recently extended its euthanasia legislation to minors, making it the first legislation in the world that does not specify any age limit. I consider two strands in the opposition to this legislation. First, I identify five arguments in the public debate to the effect that euthanasia for minors is somehow worse than euthanasia for adults—viz. arguments from weightiness, capability of discernment, pressure, sensitivity and sufficient palliative care—and show that these arguments are wanting. Second, there is another position in (...) the public debate that wishes to keep the current age restriction on the books and have ethics boards exercise discretion in euthanasia decisions for minors. I interpret this position on the background of Velleman’s “Against the Right to Die” and show that, although costs remain substantial, it actually can provide some qualified support against extending euthanasia legislation to minors.

The intention of this paper is to relate the various standpoints regarding anxiety and uncertainty. Within the humanities and social sciences, research is pursued in many different disciplines without much interaction between them. Everyone's thinking is based on concepts which are domain-specific, and the distinctions, methods and arguments used are the ones that are generally accepted within the discipline. The divergent conclusions constitute pieces of a puzzle that are seldom if ever put together. There are even doubts about whether such (...) a puzzle can be put together. It can hardly be denied, however, that inspiration is to be found in a consideration of the views and findings of colleagues from other disciplines who are working on the same problems. Now that we have as our guests two prominent academics, each with specific views about our subject, we should take this opportunity to discuss together some of the sociological, anthropological, economic, philosophical and theological approaches to anxiety and uncertainty.If a number of well-known authors are to be believed, lack of trust, uncertainty and insecurity affect the most affluent and modern societies. In French one speaks of précarité , in German of Unsicherheit and Risikogesellschaft , and in English of “fear”, “risk” and “insecurity” . All modern Western societies seem to be afflicted with the same dismal and frustrating human experience.Belgian society is no exception to this. In recent years we have regularly been subjected to the emotional reactions provoked by sensational events in the areas of politics , justice and public health . Less spectacular but no less real were the results of opinion polls which showed that confidence in public institutions in general, and politics in particular, is at an all-time low. (shrink)

Suppose that we acquire various items of information from various sources and that our degree of confidence in the content of the information set is sufficiently high to believe the information. Now a new item of information is being presented by a new information source. Are we justified to add this new item of information to what we already believe? Consider the following parable: “I go to a lecture about wildlife in Greenland which was supposed to be delivered by an (...) expert in the field. When I arrive I notice that the expert has excused himself and that the biology department has sent a newcomer to fill in for him. I have no beliefs about wildlife in Greenland, but I do have some beliefs about Greenland’s climate and about the kinds of climate conditions that various types of wildlife favor. Suppose that our newcomer proclaims that large colonies of elk roam in a particular valley on the southern tip of Greenland. Then I would certainly be willing to accept this item of information. But suppose that he proclaims that large colonies of armadillos roam in the same valley. Then I would not be willing to accept this item of information. Why do I accept the former but not the latter item of information? Let us suppose that neither item of information is logically inconsistent with what I already believe. Clearly, the former item of information is not inconsistent. But also the latter item is not: after all, there may be small pockets of Greenland with special climatological conditions and some Texan sailors may have set loose a pair of armadillos as a practical joke. But whereas the former item of information is quite plausible given my previous beliefs, the latter item of information is not. And this is what makes for the difference. Now suppose that our newcomer proclaims that large colonies of wild boars roam this valley in Greenland. I am not that sure anymore. Given everything I believe, I find wild boars in Greenland more plausible than armadillos in Greenland, but certainly less plausible than elk in Greenland. Had our expert presented the lecture and provided precisely the 2 same information, then I would have been willing to adopt the belief that there are wild boars in Greenland, but, with our newcomer delivering the lecture, I am not willing to do so. It is not that I would believe anything out of the expert’s mouth: also he could not have convinced me that there are armadillos in Greenland. But when it comes to wild boars, the difference between the expert’s and the newcomer’s credentials simply makes for the difference.” What we learn from this story is that the question of belief expansion has something to do with the reliability of the information source as well as with the plausibility of the new information, given what I already believe. The more reliable the information source is, the less plausible the new information needs to be given what I already believe, for me to be justified to add the belief to our belief set. The more plausible the new information is given what I already believe, the less reliable the information source needs to be given what I already believe, for me to be justified to add the belief to my belief set. The challenge is: can a precise account of this relationship be provided? (shrink)

When, in Plato’s Parmenides 155e4–157b5, Parmenides refers to the instant (ἐξαίφνης), he is alluding to a paradox of Zeno, and not to an argument of Plato. Thus, in the second part of the Parmenides, the speaker is a fair representation of the historical Parmenides, and not a figment of Plato’s imagination.

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.

Marked sharply by its time and place (Paris in the 1970s), this early theological text by Jean-Luc Marion nevertheless maintains a strikingly deep resonance with his most recent, groundbreaking, and ever more widely discussed phenomenology. And while Marion will want to insist on a clear distinction between the theological and phenomenological projects, to read each in light of the other can prove illuminating for both the theological and the philosophical reader - and perhaps above all for the reader who wants (...) to read in both directions at once, the reader concerned with those points of interplay and undecidability where theology and philosophy inform, provoke, and challenge one another in endlessly complex ways." "In both his theological and his phenomenological projects Marion's central effort to free the absolute or unconditional (be it theology's God or phenomenology's phenomenon) from the various limits and preconditions of human thought and language will imply a thoroughgoing critique of all metaphysics, and above all of the modern metaphysics centered on the active, spontaneous subject who occupies modern philosophy from Descartes through Hegel and Nietzsche.

Meijs and Douven (2005) present an interesting pair of alleged counterexamples and an algorithm to generate such counter-examples to our criterion for a coherence quasi-ordering over information sets as outlined in our 2003a and 2003b accounts. We agree that our criterion does not always provide an ordering when we would intuitively say that one set is more coherent than the other. Nonetheless, we think that our criterion can be salvaged.

We consider a special set of risky prospects in which the outcomes are either life or death. There are various alternatives to the utilitarian objective of minimizing the expected loss of lives in such prospects. We start off with the two-person case with independent risks and construct taxonomies of ex ante and ex post evaluations for such prospects. We examine the relationship between the ex ante and the ex post in this restrictive framework: There are more possibilities to respect ex (...) ante and ex post objectives simultaneously than in the general framework, i.e. without the restriction to binary utilities. We extend our results to n persons and to dependent risks. We study optimal strategies for allocating risk reductions given different objectives. We place our results against the backdrop of various pro-poorly off value functions for the evaluation of risky prospects. (shrink)

This paper is the text of a lecture given at Sofia University St. Kliment Ohridski on 2 November 2023 at the invitation of Professor Irena Kristeva. Its purpose is to retrace the path of my research, from the question of the Animal in the eighteenth century to the theme, at the same time, of the environment associated with the construction of the modern Ego and which gave rise to my latest book published in 2020: Figures of the Self and the (...) Natural Environment in the Eighteenth Century. Throughout, the common thread remains to understand the link between these two processes and the new Anthropology being established at the time, whether in terms of the new definition of Man in general in relation to the Animal, or of the Self in relation to the natural Environment. At the same time, this sensitivity to Nature paved the way for our contemporary ecology, both scientific and political. (shrink)

Does Descartes belong to metaphysics? What do we mean when we say "metaphysics"? These questions form the point of departure for Jean-Luc Marion's groundbreaking study of Cartesian thought. Analyses of Descartes' notion of the ego and his idea of God show that if Descartes represents the fullest example of metaphysics, he no less transgresses its limits. Writing as philosopher and historian of philosophy, Marion uses Heidegger's concept of metaphysics to interpret the Cartesian corpus--an interpretation strangely omitted from Heidegger's own history (...) of philosophy. This interpretation complicates and deepens the Heideggerian concept of metaphysics, a concept that has dominated twentieth-century philosophy. Examinations of Descartes' predecessors (Aristotle, Augustine, Aquinas, and Suarez) and his successors (Leibniz, Spinoza, and Hegel) clarify the meaning of the Cartesian revolution in philosophy. Expertly translated by Jeffrey Kosky, this work will appeal to historians of philosophy, students of religion, and anyone interested in the genealogy of contemporary thought and its contradictions.

According to a popular version of the current evolutionary attitude in cognitive science, the mind is a massive aggregate of autonomous innate computational devices, each addressing specific adaptive problems. Our aim in this paper is to show that although this version of the attitude, which we call GOFEP , does not suffer from fatal flaws that would make it incoherent or otherwise conceptually inadequate, it will nevertheless prove unacceptable to most cognitive scientists today. To show this, we raise a common (...) objection to the concept of innateness, not to mount an attack on GOFEP but to study how its proponents have attempted to meet that challenge. The aim of this move is to show that GOFEP cannot face the challenge without, as it were, losing its soul. There is, or so we will argue, something deep at the heart of GOFEP that prevents its proponents from meeting the challenge. (shrink)

Applies the models to the confirmation of scientific hypotheses by means of partially reliable test instruments.

À la différence de la plupart des autres commentateurs, je soutiens que l’histoire de l’univers évoquée dans le mythe du Politique comprend trois périodes : le règne de Kronos décrit en 271c3-272d6, le monde laissé à lui-même évoqué en 272d6-273e4 et le règne de Zeus, le nôtre, décrit en 273e4-274d7. La période d’abandon ne peut correspondre à la nôtre, au cours de laquelle, suivant Platon, les dieux sont actifs et jouent un rôle important. Un passage du Timée et surtout le (...) dixième livre des Lois laissent en effet entendre qu’il s’agit là d’une « expérience de pensée », destinée à illustrer dans quel état serait le monde s’il était livré a lui-même.

Il faut aborder avec scepticisme les quelques références à Pythagore et aux Pythagoriciens contenues dans les dialogues de Platon, car il est difficile de prendre la mesure effective d'une influence pythagoricienne sur l'Athénien. En fait, les seules références explicites à Pythagore (Rép. X 600a-b) et aux Pythagoriciens (Rép. VII 530c-531a) ne nous disent pas grand-chose et, concernant les personnages traditionnellement considérés comme pythagoriciens, nos informations sont peu fiables, incertaines et temps contradictoires. Une telle prudence est particulièrement utile dans le cas (...) de Timée et du caractère homonyme de ce dialogue, dont le pythagorisme, bien que largement accepté par les commentateurs, semble hautement discutable. Ainsi, seule l'application d'une méthode historique prudente et lucide peut éviter cette dérive qui identifie comme pythagoricienne toute référence à la transmigration de l'âme et aux mathématiques au sens large.

L'extrême barbarie de la seconde guerre mondiale, et l'espoir d'une vie différente pour l'humanité, ont amené M. Merleau-Ponty à réfléchir sur le marxisme - théorique d'une part, stalinien d'autre part. Notre projet consiste à suivre son cheminement intellectuel à cet égard depuis ses premiers écrits politiques de '45 jusqu'en I960, quelques mois à peine avant sa mort subite survenue il y a exactement trente ans, en mai 1961. Mais en quoi est-il pertinent, à l'heure où un vent d'Histoire plane sur (...) l'Est, de revenir sur des textes dont certains atteindront bientôt le demi-siècle ? C'est que l'auteur a vu clair avant presque tout le monde, de telle sorte qu'il réussit à identifier, inscrite dès l'origine dans son propre système, l'asphyxie inévitable du régime soviétique. Aussi, lire le Merleau-Ponty de ces années pas si lointaines, c'est lire à notre avis l'URSS de Gorbatchev et voir également s'épanouir la nouvelle Europe depuis Prague jusqu'à Sofia. C'est comprendre du même souffle - ce que n'eût point désavoué Marx - qu'on ne saurait bâillonner indéfiniment, enracinée dans le tissu de l'homme, la Volonté-de-liberté des peuples et des nations.The extreme barbarity of the Second World War, and the hope for a different life for Humanity, lead Merleau-Ponty to reflect on marxism, theoretical as well as Stalinian. Our aim is to follow his intellectual progress on this subject since his first political writing, from 1945 until I960, that is, just a few months before his sudden death in may 1961. However, where is the relevance to come back to these fifty years old texts when History blows on eastern countries? Simply because Merleau-Ponty has foreseen the present situation almost before any other analyst, in such a way that he identified successfully the unavoidable asphyxia of the soviet regimen, as inscribed at the very outset of this political system. To read the Merleau-Ponty of these years, it is, do we think, to read the USSR of Gorbatchev, and to see also the new Euro pa to expand, from Prague to Sofia. It is also to understand, by the same occasion - and Marx would not have disavowed it -, that one cannot silence indefinitely the Will of liberty of people and nations which is routed in the nature of man.
