Cette conversation entre l’avocat et écrivain de science-fiction Jean Baret et Ariel Kyrou porte l’idée d’une double nécessité, à la fois d’expérimenter les IA génératives pour ce qu’elles permettent très concrètement et d’en extrapoler les interactions futures par les fictions les plus libres. L’enjeu est en effet d’en mener une critique qui ne soit ni technophile ni technophobe, consciente des défis créatifs et sociétaux de ces IA qui nous parlent comme à un ami en s’excusant de leurs erreurs.

Jean Klein a été l'un des principaux passeurs de la non-dualité indienne (advaita) et du yoga en France. Il a exercé et continue d'exercer une influence considérable dans les cercles de chercheurs spirituels. Dans cet ouvrage, Ludovic Fontaine a choisi d'interviewer trois enseignants, trois des principaux élèves de Jean Klein, qui s'inscrivent de manière originale et ouverte dans la perspective de leur maître. Eric Baret, Francis Lucille, et Jean-Marc Mantel présentent ici leur parcours spirituel, leur perspective propre (...) sur la non-dualité, l'éveil, la nature de la réalité. Ludovic les interroge également sur leur méthode d'enseignement : comment transmettent-ils l'éveil? Quel est leur rapport aux traditions (advaita vedanta, tantrisme cachemirien, yoga)? Quelles pratiques préconisent-ils? Qu'est-ce que ces pratiques non-duelles peuvent changer dans notre vie? Chacun pourra trouver dans ces magnifiques entretiens des renseignements précieux sur le chemin vers la liberté et la joie."--Page 4 of cover. (shrink)

Cet ouvrage est l'hommage qu'une des deux filles de Jean Klein (1912-1998), Nita, comédienne et artiste, a décidé de rendre à son père, un des plus célèbres maîtres spirituels du XXe siècle, pour le centième anniversaire de sa naissance. Nita Klein a rassemblé ici de nombreux souvenirs de conversations avec Jean Klein, des inédits, des photographies autour de la question de l'art et de la spiritualité. Jean Klein a été philosophe et un maître spirituel remarquable auteur d'une (...) oeuvre essentielle qui a infuencé de nombreux enseignants contemporains comme Eric Baret, Jean-Bouchart D'Orval, Francis Lucille, Jean-Marc Mantel etc. Même si Jean Klein n'appartenait à aucune école, sa quête de la vérité a rencontré l'Advaïta Vedânta (Non-Dualité) dont il a dit lui-même que " ce n'est pas un système, une religion, une technique. Ce n'est même pas une philosophie, c'est simplement la vérité. " Mais Jean Klein était aussi violoniste (il pratiqua toute sa vie le violon) et s'intéressait à toutes les formes d'art : au théâtre, à la peinture (il était ami de Hans Hartung), à la danse (son autre fille, Malavika, est professeur de danse indienne). Il s'agit donc dans ce livre d'une rencontre entre l'intuition d'un artiste et la recherche indienne de la vérité, recherche plus orientée vers la perception globale de la Réalité que vers les certitudes offertes par le savoir. Nita Klein nous invite à découvrir comment la spiritualité authentique conduit à la création artistique ; comment, dans l'art du théâtre, l'interprétation d'un personnage, peut atteindre à la vérité, quand la personnalité du comédien consent à s'effacer. " En l'absence du "Moi", il y a seulement la vie. ", dit Jean Klein. Et pas seulement dans le théâtre, mais dans la peinture, le dessin, la danse. La Non-Dualité, avec Jean Klein, est une ouverture à la Beauté. (shrink)

Supra-Bayesianism is the Bayesian response to learning the opinions of others. Probability pooling constitutes an alternative response. One natural question is whether there are cases where probability pooling gives the supra-Bayesian result. This has been called the problem of Bayes-compatibility for pooling functions. It is known that in a common prior setting, under standard assumptions, linear pooling cannot be nontrivially Bayes-compatible. We show by contrast that geometric pooling can be nontrivially Bayes-compatible. Indeed, we show that, under certain assumptions, geometric and (...) Bayes-compatible pooling are equivalent. Granting supra-Bayesianism its usual normative status, one upshot of our study is thus that, in a certain class of epistemic contexts, geometric pooling enjoys a normative advantage over linear pooling as a social learning mechanism. We discuss the philosophical ramifications of this advantage, which we show to be robust to variations in our statement of the Bayes-compatibility problem. (shrink)

It is widely held that under ordinal utility, utility differences are ill-defined. Allegedly, for these to be well-defined (without turning to choice under risk or the like), one should adopt as a new kind of primitive quaternary relations, instead of the traditional binary relations underlying ordinal utility functions. Correlatively, it is also widely held that the key structural properties of quaternary relations are entirely arbitrary from an ordinal point of view. These properties would be, in a nutshell, the hallmark of (...) cardinal utility. While much is obviously true in these two tenets, this note explains why, as stated, they should be abandoned. Any ordinal utility function induces a rich quaternary relation. There is such a thing as ordinal utility differences. Furthermore, this induced quaternary relation respects, apart from completeness, the most standard structural properties of quaternary relations. These properties are, from an ordinal point of view, anything but arbitrary; from a quaternary perspective only completeness should be considered the hallmark—if any—of cardinal utility. These facts are explained to be especially relevant to the critical appreciation of the ordinalist methodology. (shrink)

The representational theory of measurement has long been the central paradigm in the philosophy of measurement. Such is not the case anymore, partly under the influence of the critique according to which RTM offers too poor descriptions of the measurement procedures actually followed in science. This can be called the metrological critique of RTM. I claim that the critique is partly irrelevant. This is because, in general, RTM is not in the business of describing measurement procedures, be it in idealized (...) form. To support this claim, I present various cases where RTM can be said to investigate measurement without providing any measurement procedure. Such limit cases lead to a better understanding of the RTM project. They also illustrate some of the questions which the philosophy of measurement can explore, when it is ready to go beyond the metrological viewpoint. (shrink)

This paper examines the preference-based approach to the identification of beliefs. It focuses on the main problem to which this approach is exposed, namely that of state-dependent utility. First, the problem is illustrated in full detail. Four types of state-dependent utility issues are distinguished. Second, a comprehensive strategy for identifying beliefs under state-dependent utility is presented and discussed. For the problem to be solved following this strategy, however, preferences need to extend beyond choices. We claim that this a necessary feature (...) of any complete solution to the problem of state-dependent utility. We also argue that this is the main conceptual lesson to draw from it. We show that this lesson is of interest to both economists and philosophers. (shrink)

The Sure-Thing Principle famously appears in Savage’s axiomatization of Subjective Expected Utility. Yet Savage introduces it only as an informal, overarching dominance condition motivating his separability postulate P2 and his state-independence postulate P3. Once these axioms are introduced, by and large, he does not discuss the principle any more. In this note, we pick up the analysis of the Sure-Thing Principle where Savage left it. In particular, we show that each of P2 and P3 is equivalent to a dominance condition; (...) that they strengthen in different directions a common, basic dominance axiom; and that they can be explicitly combined in a unified dominance condition that is a candidate formal statement for the Sure-Thing Principle. Based on elementary proofs, our results shed light on some of the most fundamental properties of rational choice under uncertainty. In particular they imply, as corollaries, potential simplifications for Savage’s and the Anscombe- Aumann axiomatizations of Subjective Expected Utility. Most surprisingly perhaps, they reveal that in Savage’s axiomatization, P3 can be weakened to a natural strengthening of so-called Obvious Dominance. (shrink)

I examine the once popular claim according to which interpersonal comparisons of welfare are necessary for social choice. I side with current social choice theorists in emphasizing that, on a narrow construal, this necessity claim is refuted beyond appeal. However, I depart from the opinion presently prevailing in social choice theory in highlighting that on a broader construal, this claim proves not only compatible with, but even comforted by, the current state of the field. I submit that all in all, (...) the most accurate philosophical assessment consists not in flatly rejecting this necessity claim, but in accepting it in a suitably revised form. (shrink)

The basic axioms or formal conditions of decision theory, especially the ordering condition put on preferences and the axioms underlying the expected utility formula, are subject to a number of counter-examples, some of which can be endowed with normative value and thus fall within the ambit of a philosophical reflection on practical rationality. Against such counter-examples, a defensive strategy has been developed which consists in redescribing the outcomes of the available options in such a way that the threatened axioms or (...) conditions continue to hold. We examine how this strategy performs in three major cases: Sen's counterexamples to the binariness property of preferences, the Allais paradox of EU theory under risk, and the Ellsberg paradox of EU theory under uncertainty. We find that the strategy typically proves to be lacking in several major respects, suffering from logical triviality, incompleteness, and theoretical insularity. To give the strategy more structure, philosophers have developed “principles of individuation”; but we observe that these do not address the aforementioned defects. Instead, we propose the method of checking whether the strategy can overcome its typical defects once it is given a proper theoretical expansion. We find that the strategy passes the test imperfectly in Sen's case and not at all in Allais's. In Ellsberg's case, however, it comes close to meeting our requirement. But even the analysis of this more promising application suggests that the strategy ought to address the decision problem as a whole, rather than just the outcomes, and that it should extend its revision process to the very statements it is meant to protect. Thus, by and large, the same cautionary tale against redescription practices runs through the analysis of all three cases. A more general lesson, simply put, is that there is no easy way out from the paradoxes of decision theory. (shrink)

A recently emerging view in music cognition holds that music is not only social and participatory in its production, but also in its perception, i.e. that music is in fact perceived as the sonic trace of social rela- tions between a group of real or virtual agents. While this view appears compatible with a number of intriguing music cognitive phenomena, such as the links between beat entrainment and prosocial behaviour or between strong musical emotions and empathy, direct evidence is lacking (...) that listeners are at all able to use the acoustic features of a musical interaction to infer the affiliatory or controlling nature of an underlying social intention. We created a novel experimental situation in which we asked expert music improvisers to communicate 5 types of non-musical social intentions, such as being domineering, dis- dainful or conciliatory, to one another solely using musical interaction. Using a combination of decoding studies, computational and psychoacoustical analyses, we show that both musically-trained and non musically-trained listeners can recognize relational intentions encoded in music, and that this social cognitive ability relies, to a sizeable extent, on the information processing of acoustic cues of temporal and harmonic coordination that are not present in any one of the musicians’ channels, but emerge from the dynamics of their interaction. By manipulating these cues in two-channel audio recordings and testing their impact on the social judgements of non-musician observers, we finally establish a causal relationship between the affiliation dimension of social behaviour and musical harmonic coordination on the one hand, and between the control dimension and musical temporal coordination on the other hand. These results provide novel mechanistic insights not only into the social cognition of musical interactions, but also into that of non-verbal interactions as a whole. (shrink)

State-dependent utility is a problem for the behavioural branch of decision theory under uncertainty. It questions the very possibility that beliefs be revealed by choice data. According to the current literature, all models of beliefs are equally exposed to the problem. Moreover, the problem is solvable only when the decision-maker can influence the resolution of uncertainty. This article gives grounds to reject these two views. The various models of beliefs can be shown to be unequally exposed to the problem of (...) state-dependent utility. The problem can be argued to be solved even when the decision-maker has no influence over the resolution of uncertainty. The implications of such reappraisal for a philosophical appreciation of the revealed preference methodology are discussed. (shrink)

This new edition of "What is Literature?" also collects three other crucial essays of Sartre's for the first time in a volume of his.

Theorists have consistently maintained that the most plausible forms of objective consequentialism must be probabilistic if and only if indeterminism is true. This standard position, however popular, lacks sufficient motivation. Assume determinism to be true and an attempt will be made to show that attractive forms of objective consequentialism must be probabilistic - and not for reasons related to our epistemic limitations either. -/- Here it is argued that all extant objective formulations of consequentialism fail to deliver the normative implications (...) that the spirit of objective consequentialism requires. My argument rests upon the claim that certain pairs of subjunctive conditionals with identical antecedents and incompatible consequents are such that neither of the pair is true. -/- Upon leveling the objection, the concept of an "objective" subjunctive probability is introduced and utilized in the transformation of a subjective version of expected act utility consequentialism into an objective version, one that is capable of dealing with the difficulties posed by the objection. I end by indicating some ways in which the closest thing to a plausible, objective form of consequentialism might be developed. (shrink)

In this paper, I examine the decision-theoretic status of risk attitudes. I start by providing evidence showing that the risk attitude concepts do not play a major role in the axiomatic analysis of the classic models of decision-making under risk. This can be interpreted as reflecting the neutrality of these models between the possible risk attitudes. My central claim, however, is that such neutrality needs to be qualified and the axiomatic relevance of risk attitudes needs to be re-evaluated accordingly. Specifically, (...) I highlight the importance of the conditional variation and the strengthening of risk attitudes, and I explain why they establish the axiomatic significance of the risk attitude concepts. I also present several questions for future research regarding the strengthening of risk attitudes. (shrink)

A travers une analyse des concepts d’affirmation originaire, d’attestation et de reconnaissance, cet article tente de reconstituer le sens et les motivations du cheminement réflexif qui conduit Ricœur de L’Homme faillible à Soi-même comme un autre et à Parcours de la reconnaissance . Pour ce faire, il s’efforce d’abord de montrer ce qui fait la continuité profonde, de problématique et de méthode, du projet anthropologique ricœurien; afin de dégager ensuite les difficultés centrales liées à l’idée d’une constitution poétique du soi, (...) qui conduisent Ricœur à réélaborer les concepts directeurs de son herméneutique du soi. A la lumière du dialogue constant de Ricœur avec la philosophie de Nabert, il tente enfin de montrer comment les concepts d’attestation et de reconnaissance trouvent, pour l’essentiel, leur genèse dans un approfondissement de la notion d’affirmation originaire, lui-même prolongé par une réflexion sur le témoignage.  .

In this paper, I examine a neglected debate between Francisco Suárez and Pedro Hurtado de Mendoza about the unity of composite substances. There was a consensus among the Jesuits on the fact that the per se unity of composite substances requires something in addition to matter and form. Like most Jesuits, Suárez and Hurtado further agree on the fact that this additional ingredient is not a full-blown thing, but a “mode of union.” However, while Suárez claims that the union is (...) achieved through a single mode, Hurtado maintains that it is necessary to postulate two distinct modes of union, one modifying form and another modifying matter. I argue that this disagreement actually reflects an important ontological debate about the nature of the items that serve as the cement of things and that it eventually leads later Jesuits like Rodrigo de Arriaga to conceive of union as a polyadic or “straddling” mode.

The relation between extension and impenetrability is a major issue in the Descartes-More correspondence, which implies an analysis of the concept of extension. The mereological structure partes extra partes is a crucial element here. Both philosophers hold two opposed views of this mereological structure. I try to show that these two views can be traced back to scholastic discussions on quantity’s relation to extension. This background provides a vantage point, which enables to propose a new construal of the argumentative exchange (...) around impenetrability, and which casts some light too on our understanding of two properties – spissitude and indiscerpibility – which More attributes to spiritual extension in his later writings.

This view encouraged theorists to consider artistic geniuses the high-priests of humanity, creators of works that reveal the invisible essence of the world."--BOOK JACKET.

How to reconcile monadic simplicity with the successive plurality of the monadic states ? The doctrine of continued creation seems to entail the existence of independent temporal parts and thus lead to the thesis that the world contains only transitory things. I try to show how Leibniz has the resources to get out of this quandary. The analysis of the concept of extension shows that a plurality of states does not constitute a divisible aggregate. Then I examine the Leibnizian interpretation (...) of continued creation, by com- paring it to the scholastic and Cartesian Background. From thence I conclude that Leibniz’s final thesis is that monads are wholly present at each moment of their duration. (shrink)

Alors qu’il était précepteur en Suisse, le jeune Hegel traduisit minutieusement un libelle révolutionnaire dénonçant l’oppression que les autorités bernoises exerçaient sur le Pays de Vaud. Il publia ces Lettres de Jean-Jacques Cart à son retour en Allemagne, en 1798, sous le couvert d’un anonymat qu’il ne leva jamais. Derrière le caractère anecdotique de cette première publication, on peut déceler des enjeux qui conduisirent à l’instauration de l’idéalisme spéculatif. Le motif de la lutte pour la reconnaissance, en particulier, semble (...) y trouver sa première apparition. Plus fondamentalement cette première publication éclaire le travail d’élaboration stylistique conduisant progressivement au système, avec, à l’horizon, la question de la portée pratique de la philosophie.

The history of the relations between Leibniz and Spinoza is a matter of philosophical and scholarly controversy. This chapter aims to refer to the first thesis as the Necessity of Actuality and to the second thesis as the Plenitude of Possibilities. It examines how Leibniz's stance with respect to these two theses, and more generally his views on modality, grew out as a response to Spinoza's views. Leibniz explicitly connects Spinoza's attributes with the concept of a world. As most commentators, (...) Leibniz reads Spinoza as a necessitarian, which is a natural interpretation. The difference between Leibniz's and Spinoza's views would reside in their conceptions of God and of the mechanism whereby the actual world comes to exist. Leibniz entertains the hypothesis of reality encompassing a plurality of actual worlds, which seems to achieve the Plenitude of Possibility. (shrink)

In 1982-83, I was preparing my volume on the Belgian cartoonist Hergé. During the Second World War, Hergé’s comic strips appeared daily in the newspaper Le Soir. Since I wanted to analyze the influence of the rightist thought on Hergé and Tintin, I borrowed most of the copies of Le Soir available in this country through interlibrary loan. Examining the newspaper, I came across Paul de Man’s articles, which were sometimes on the same page as the comic strips. I showed (...) these articles to some colleagues related to or teaching at Harvard University. I specifically recall an afternoon with a colleague from Boston University whose specialty is the hunting of presumed French fascist intellectuals; we discussed together the possible bridges between de Man’s contemporary thought and his former intellectual engagement during the Second World War.That is to say that, as far as I know, several people at Harvard and in the Boston area were aware of de Man’s former affiliation with rightist circles. One can ask why it took five more years for the “scandal” to appear: why this “sudden” revelation after several years of silence and dissimulation? Compared to the fact that Hergé had constantly been confronted with his political past, one can wonder how strongly Paul de Man’s “secret” was kept. Jean-Marie Apostolidès is professor of French at Stanford University. He is currently writing an essay on the anthropological reading of literature. His article “Molière and the Sociology of Exchange” appeared in the Spring 1988 issue of Critical Inquiry. (shrink)

Starting from a genesis of the concept of narrative identity, this article attemps to interpret the constitution process of our narrative identities through a systematic and synthetic review of the main contributions of the Ricœurian theory of imagination, from Freedom and Nature to Oneself as Another.

Qu'est-ce que la réalité? Jamais un état de fait. C'est une oeuvre. Une oeuvre d'art qui ne correspond qu'à un moment d'une mise en oeuvre dont nous sommes de plus en plus les maîtres d'oeuvre. C'est à partir de ce constat que l'auteur démontre implacablement l'inanité du réalisme. Ce qu'illustre à ses yeux aussi bien la révolution impressionniste, qui fit exploser le réalisme pictural, que le dépassement nécessaire de la confrontation matérialisme-idéalisme ou que le flamboiement de l'utopisme gaullien de 1940 (...) confronté au réalisme pétainiste. À travers cette thèse singulière et stimulante qui débouche sur une nouvelle approche de la philosophie et de l'histoire de son rapport au réel, Jean-François Kahn incite à de salutaires remises en question qui ne manqueront pas de faire grincer quelques dents.

Rising exclusion rates indicate the continuing marginalisation of many young people in education in the UK. Working-class boys, children living in poverty, and children with additional/special educational needs are among those experiencing a disproportionate rate of exclusion. This book traces the processes of exclusion and alienation from school and relates this to a changing social and economic context. Jean Kane argues that policy on schooling, including curricular reform, needs to be re-connected to the broad political pursuit of social justice, (...) and presents compelling case studies of excluded pupils, showing the multi-faceted identities of pupils, with a particular focus on masculine and feminine identities. This invaluable contribution to the literature offers an alternative analysis where the social identities of pupils are shown to be tied up with their exclusion from school. Themes investigated include: the meanings of school exclusions social class, gender and schooling social identities of excluded pupils negotiating identities in school: moving towards exclusion exclusions and young people’s lives improving participation in schooling. Providing fascinating reading for teachers, social workers, researchers and policy-makers this book considers how educational disadvantage might be addressed through recognition of the gender and class identities of pupils.

RESUME L’hypothèse que tente d’esquisser cet article est que l’idée ricœurienne d’une médiatisation dynamique des contradictions de l’imaginaire social présuppose une corrélation originaire de l’idéologie et de l’utopie qui ne peut elle-même être comprise qu’à partir de l’événement de l’institution d’un imaginaire social constituant. Dans un premier temps, l’article s’efforce de cerner ce qui fait la spécificité de la théorie ricœurienne de l’idéologie et de l’utopie comme « pratiques imaginatives », en soulignant à ce titre l’influence déterminante des thèses de (...) Jacques Ellul sur l’idéologie. Puis, dans un second temps, il s’engage dans une analyse régressive qui conduit de la réappropriation ricœurienne de la conception dialectique de l’idéologie et de l’utopie exposée par Mannheim à l’idée d’un fondement événementiel de ces deux formes opposées de l’imaginaire social. Mots-Clés : Evénement, idéologie, utopie, Ellul, Mannheim. ABSTRACT This paper attempts to sketch out the hypothesis that the Ricœurian conception of a dynamic mediatization of the contradictions of the social imaginary presupposes an original correlation between ideology and utopia, which can itself be understood only from the event that institutes a constitutive social imaginary. The first part of the paper marks out the specificity of the Ricœurian theory of ideology and utopia in terms of “imaginative practices”, underlining the determining influence of Jacques Ellul’s theses on ideology. The second part tries to develop a regressive argument, starting from the Ricœurian re-appropriation of Mannheim’s dialectical conception of ideology and utopia, and leading back to the idea of an event foundation for these two opposed forms of the social imaginary. Keywords : Event, Ideology, Utopia, Ellul, Mannheim. (shrink)

James Cain issues forth a two-pronged attack against classical forms of act utilitarianism, elucidating objections from infinite utility streams and distributive justice through his novel examples.1 In his first example, we are to imagine an infinite number of immortals, living on an infinitely long street (Elm Street), bracing to suffer an infinite amount of migraine pain with the onset of this horrific disease. Left untreated, the disease would wreak havoc among our immortals in the following way.

Résumé Cet article cherche à comprendre en quel sens il est possible de parler de « forme de vie » dans le cadre de la théorie hégélienne de la Bildung. Par le terme de Bildung (formation, culture, éducation), Hegel pense l’activité qui consiste à former la vie, c’est-à-dire à faire passer la première nature de l’individu à une seconde nature sociale. De ce point de vue, la philosophie hégélienne entre en dialogue avec la philosophie sociale contemporaine dans une perspective naturaliste (...) : elle permet de mettre en avant le rôle de la socialisation du corps naturel dans les relations de reconnaissance ou de domination.

Introduction Tf HE ideas we shall deal with here represent only one aspect of the teaching transmitted during his life by GI Gurdjieff. ...

Le raisonnement par lequel Hume établit l'ori- gine empirique de Vidée de cause repose implicitement sur un principe de possibilité a priori et même de probabilité a priori, dont Hume n'a pas remarqué le caractère rationnel, tant il paraissait naturel. Ce principe est identique à celui sur lequel Pascal fonde le calcul des probabilités. Si l'on admet sa légitimité, il en résulte deux conséquences capita- les pour la théorie de la connaissance : 1 - La raison ne se limite pas (...) aux seuls principes logiques en oeuvre dans la déduction mais doit reconnaître que ce qui est également pensable est également probable a priori. 2 - Ce principe de probabilité fournit une preuve de l'existence d'une réalité extérieure à la conscience, que l'on cherchait en vain dans le principe de causalité.

In this paper, we look for the relevance of chaos in the well-known Hicks-Samuelson's oscillator model investigating the endogenous fluctuations of the national income between two limits: full employment income and under-employment income. We compute the Lyapunov exponent, via Monte- Carlo simulations, to detect chaos in the evolution of the income between both limits. In the case of positive Lyapunov exponent and large values of the parameter (i.e. marginal propensity to consume and technical coefficient for capital), the evolution of income (...) is seen to be chaotic. The model also may contain a quasi-periodic attractor that can be chaotic or not. (shrink)
