Au Centre Pompidou-Metz, faisant écho à l'exposition inaugurale, un colloque international a étudié de manière pluridisciplinaire et transversale la question du chef-d'œuvre. Loin de se focaliser sur le débat esthétique, les diverses approches ont assigné le droit, l'histoire, la sociologie, l'économie et les sciences exactes, pour mieux soumettre cet "objet" à un véritable examen clinique. Cette question ne serait-elle plus d'actualité? Loin s'en faut! Entre cœur et raison, la sacralisation des œuvres d'art produit toujours autant de savoirs, de savoir-faire et (...) de savoirs sur le faire. Mettant en avant le patrimoine, restaurant les objets de l'art, les reconstituant, favorisant le tourisme culturel, exhumant le vrai, condamnant le faux : à sa mesure, le "chef-œuvre" dynamise encore et toujours les divers moments de l'art.

This paper defends the view that Newtonian forces are real, symmetrical and non-causal relations. First, I argue that Newtonian forces are real; second, that they are relations; third, that they are symmetrical relations; fourth, that they are not species of causation. The overall picture is anti-Humean to the extent that it defends the existence of forces as external relations irreducible to spatio-temporal ones, but is still compatible with Humean approaches to causation (and others) since it denies that forces are a (...) species of causation.

The amount of information conveyed by linguistic conventions depends on their precision, yet the codes that humans and other animals use to communicate are quite ambiguous: they may map several vague meanings to the same symbol. How does semantic precision evolve, and what are the constraints that limit it? We address this question using a multiplayer gaming app, where individuals communicate with one another in a scaled-up referential game. Here, the goal is for a sender to use black and white (...) symbols to communicate colors. We expected that the players’ mappings between symbols and colors would grow more specific over time, through a selection process whereby precise mappings are preferentially copied. We found that players become increasingly more precise in their use of symbols over the course of their interactions. This trend did not, however, result from selective copying of precise mappings. We explore the implications of this result for the study of lexical ambiguity, Zipf's Law of Meaning, and disagreements over semantic conventions. (shrink)

In Study 1, we examined the moderating impact of alexithymia (i.e., a difficulty identifying and describing feelings to other people and an externally oriented cognitive style) on the automatic processing of affective information. The affective priming paradigm was used, and lower priming effects for high alexithymia scorers were observed when congruent (incongruent) pairs involving nonverbal primes (angry face) and verbal target were presented. The results held after controlling for participants' negative affectivity. The same effects were replicated in Studies 2 and (...) 3, with trait anxiety and depression entered as additional covariates. In Study 3, no moderating impact of alexithymia was found for verbal-facial pairs suggesting that the results cannot be merely explained in terms of transcoding limitations for high alexithymia scorers. Overall, the present results suggest that alexithymia could be related to a difficulty in processing and automatically using high arousal emotional information to respond to concomittant behavioural demands.

High and low alexithymia scorers were confronted with a modified visual oddball task that allowed the study of categorical perception of emotional expressions on faces. Participants had to quickly detect a deviant (rare) morphed face that shared or did not share the same emotional expression as the frequent one. Expected categorical perception effects, which were also neurophysiologically indexed, showed that rare stimuli were detected faster if they depicted a different emotional expression compared to rare stimuli depicting the same emotional expression (...) than the frequent one. Even if no differences were observed at a behavioural level, high alexithymia scorers evidenced overall delayed neurophysiological responses in components related to the attentional processing of rare emotional faces. Moreover, the categorical perception effects for event-related components associated with the attentional processing were smaller in high alexithymia scorers and were even absent for anger. These results show that high alexithymia scorers present discrimination delays that are already observed at the attentional level. (shrink)

What are economic exchanges? The received view has it that exchanges are mutual transfers of goods motivated by inverse valuations thereof. As a corollary, the standard approach treats exchanges of services as a subspecies of exchanges of goods. We raise two objections against this standard approach. First, it is incomplete, as it fails to take into account, among other things, the offers and acceptances that lie at the core of even the simplest cases of exchanges. Second, it ultimately fails to (...) generalize to exchanges of services, in which neither inverse preferences nor mutual transfers hold true. We propose an alternative definition of exchanges, which treats exchanges of goods as a special case of exchanges of services and which builds in offers and acceptances. According to this theory: (i) The valuations motivating exchanges are propositional and convergent rather than objectual and inverse; (ii) All exchanges of goods involve exchanges of services/actions, but not the reverse; (iii) Offers and acceptances, together with the contractual obligations and claims they bring about, lie at the heart of all cases of exchange.

In this work, the author has two complementary objectives. Firstly, to demonstrate the contemporaneity of the Middle Ages and secondly, the false novelty of the Modern Times. The author shows the medieval horizon of modernity and, therefore, the false disjunction established between its origin, as rupture and break, considering the Middle Ages as Dark Ages. The author analyses several moments considered as indicating that rupture and several topics traditionally considered as modern, in order to demonstrate their medieval filiations. The author (...) does not pretend to defend the historical continuity within the logic of modernity, but the possibility of a genealogy of “oblivions” characterizing our age, in order to defend and reconsider the non- contemporary within a new definition of the contemporary and the study of medieval philosophy for herself, beyond her pre-modernity, in a post-modern order.

La question de la liberté est à la fois fondamentale et posée en des termes qui la rendent insoluble : comment penser une action libre si l'on admet que les phénomènes sont soumis à la causalité? En analysant l'émergence du concept de libre arbitre, Olivier Boulnois propose une autre généalogie de la morale.00Sous un problème en apparence évident (la liberté de la volonté, née de l'idée de responsabilité, et la difficulté de penser cette liberté dans un monde régi par (...) des rapports de cause à effet), l'auteur débusque une série de questions correspondant aux différents sens de la liberté : la liberté à l'égard d'une contrainte n'est pas la liberté à l'égard des causes extérieures ou internes ; elle peut viser la liberté d'agir, mais aussi la liberté de choisir entre plusieurs options et la liberté de vouloir ou de ne pas vouloir. Les approches classiques et modernes (celles d'Aristote, d'Augustin, de Descartes ou de Leibniz) sont confrontées aux pensées critiques des XlXe-XXe siècles (de Nietzsche à Freud et Wittgenstein). D'une liberté à l'autre, les questions ne sont pas les mêmes - ainsi, Aristote élabore une théorie cohérente de l'action sans poser la question de la liberté.00Il fallait faire apparaître l'± impensé? des théories du libre arbitre pour poser correctement la question, et espérer la résoudre.

Cette étude explore les ruptures et les transformations imposées à la doctrine de la liberté d’indifférence au XVIIe siècle. Celle-ci, d’origine scotiste, mais modifiée par les controverses autour de Molina, s’oppose d’abord aux théories thomistes de la prédétermination physique. L’œuvre de Gibieuf, pour qui l’indifférence décroît proportionnellement à l’évidence du bien, en change radicalement la signification. Désormais, certains thomistes pourront accepter l’indifférence, tandis que le jansénisme en fait un repoussoir. La pensée de Descartes apparaît ainsi comme une stratégie pour faire (...) une place à la liberté sans entrer dans les querelles théologiques : elle repose sur deux indéterminations successives, destinées à la rendre compatible tantôt avec la prédétermination, tantôt avec la science moyenne moliniste. Ainsi, Descartes est le seul philosophe classique à faire une place à la liberté d’indifférence, mais il est aussi celui qui la repousse à une place inférieure, amorçant ainsi un refoulement que consommeront ses successeurs.This study aims at exploring the splits and transformations which the theory of freedom of indifference has undergone during the XVIIth century. This theory has a Scotistic origin, but it was modified by the controversies around Molina. It is primarily directed against the « Thomsitic » theories of physical predetermination. The works of Gibieuf, for whom indifference decreases proportionally to the growth of evidence and goodness, has radically changed its meaning. Hereafter, a few Thomists will agree with the indifference theory, while it serves as a foil to Jansenists. Descartes’ thought appears thus as a strategy to give way to freedom without entering into theological controversies. It is grounded on two successive indeterminations, which make it compatible, once with predetermination, once with the molinist scientia media. Thus, Descartes is the sole classical philosopher who admits some indifference, but he is also the sole to force it back to an inferior position, beginning thus a containment which will be accomplished by his successors.

In his ‘Theory of Light and Colours’, presented to the Royal Society in November 1801, Thomas Young defended a mechanical explanation of the coloured fringes observed outside of the shadow of an opaque object – the so-called ‘colours by inflection’ – that was based on the hypothesis of an ethereal density gradient surrounding all material bodies. However, two years later, he publicly rejected that hypothesis, without giving much detail of his reasons. Although Geoffrey Cantor has demonstrated the crucial role of (...) mechanical and astronomical arguments in explaining the withdrawal of this fundamental hypothesis long ago, the purpose of this article is to draw deeper attention to a set of experiments performed by David Brewster on the inflection of light, described in a letter he addressed to the Royal Society in January 1802, but was retained by William Herschel, and finally was neither read before the Society, nor published in its Philosophical Transactions. For the hypothesis that will be evaluated here is that these unpublished experiments of Brewster’s were eventually known to Young through the mediation of Herschel, and eventually played a significant role in Young’s rejection of his ether distribution hypothesis.

This article attempts to clarify an “argument from reason” set forth by C. S. Lewis in his Miracles. While there are various contemporary interpretations of the argument, Lewis intended to expose the “cardinal difficulty of naturalism.” First, this article seeks to clarify both Lewis’s argument and the understanding of naturalism that it presupposes. Second, philosophers of religion—especially, William Hasker and Alvin Plantinga—have significantly contributed to the argument’s contemporary discussion, and so their views are addressed with the intent to show how (...) they differ from Lewis’s contribution. C. S. Lewis’s argument from reason was and is remains to this day philosophically timely and deserving of serious consideration. (shrink)

To be optimistic, it is standardly assumed, is to have positive expectations. I here argue that this definition is correct but captures only one variety of optimism – here called factual optimism. It leaves out two other important varieties of optimism. The first – focal optimism – corresponds to the idea of seeing the glass half full. The second – axiological optimism – consists in the view that good is stronger than bad. Those three varieties of optimism are irreducible to (...) each other and do not belong to a common kind. I define each of these, characterize their respective correctness conditions, and contrast hope with optimism. (shrink)

Samuel Johnson claimed to have refuted Berkeley by kicking a stone. It is generally thought that Johnson misses the point of Berkeley's immaterialism for a rather obvious reason: Berkeley never denied that the stone feels solid, but only that the stone could exist independently of any mind. I argue that Johnson was on the right track. On my interpretation, Johnson’s idea is that because the stone feels to resist our effort, the stone seems to have causal powers. But if appearances (...) are to be taken at face value, as Berkeley insists, then the stone has causal powers. I argue that such causal powers threaten not only Berkeley’s view that only minds are active, but also, and more fundamentally, his central claim that sensible things depend on perception. (shrink)

On nomme ici « un sexe » une manière singulière d’envisager une pratique sexuelle et de s’y engager. Michel Leiris est exemplaire dans sa manière d’exposer une pratique que l’on pourrait qualifier, en usant d’un de ses propres termes de « timoré ». Loin d’être naturelle ou immédiatement exaltante, l’acte sexuel se présente plutôt pour lui comme une épreuve, certes sans violence ni dimension sacrale, mais qui peut néanmoins être comparée, comme l’écriture elle-même, à une sorte de corrida intime.

Can one refute Berkeleyan phenomenalism by arguing that sensory objects seem mind-independent, and that, according to Berkeley, experience is to be taken at face value? Relying on Mackie’s recent discussion of the issue, I argue, first, that phenomenalism cannot be straightforwardly refuted by relying on perceptual or bodily experience of mind-independence together with the truthfulness of experience. However, I maintain, second that phenomenalism can be indirectly refuted by appealing to the bodily experience of resistance. Such experience presents us with the (...) causal activity of the resisting physical object. If experience is truthful, as the phenomenalist has it, physical objects are causally active. But then their effects no longer depend on our perceiving them, on pain of overdetermination. (shrink)

Phenomenology is an emerging field within the broader domain of African and Africana philosophy. The phenomenological method, with its various approaches to studying the meaning of lived experience, is at the core of the thought of African philosophers such as Paulin Hountondji, Dismas A. Masolo, Achille Mbembe, Mabogo More, Tsenay Serequeberhan, Noel Chabani Manganyi, and proponents of Africana Philosophy such as WEB Du Bois, Frantz Fanon, Lucius Outlaw, Lewis Gordon, George Yancy, and Linda Martin Alcoff. Technically, the term “African phenomenology” (...) is not used as widely, or introduced as systematically, as Africana phenomenology. The aim of this chapter is to introduce some of the central issues and theorists of the field of African phenomenology. As the subtitle of this chapter indicates, its scope is limited to what one may call introductory perspectives in African phenomenology. The idea is to outline for further investigation some thematically related contributions to African phenomenology with specific reference to the grounding work of Paulin Hountondji as related to works of Kwasi Wiredu and Dismas A. Masolo. Hountondji’s critical adoption of Husserl’s classic phenomenological approach offers a broad, foundational scope, which makes it particularly suitable for a basic introduction to African phenomenology.

In African Philosophy and Enactivist Cognition: The Space of Thought (2023), Bruce B. Janz introduces what he calls an enactivist African philosophy. The book makes a significant contribution to African philosophy as no other work has yet made the connection between African philosophy and enactivism. This article’s aim is to give a critical response to the book. It starts with some background by connecting Enactivist Cognition with Janz’s earlier Philosophy in an African Place (2009). This is followed by a brief (...) discussion of his introduction to enactivist African philosophy and its connection to texts in African philosophy. The article closes with a discussion of some issues that Enactivist Cognition raises. (shrink)

The thought of the psychoanalytical thinker, Jacques Lacan, is examined in this paper with a view to ascertaining the place and function of the so-called imaginary in it, the symbolic as well as the 'real'. The extent to which the imaginary or realm of images is construed by Lacan as being the order of identification and a (spurious) sense of unity of the ego or self, is contrasted with the symbolic (or linguistic) order as that of the subject and of (...) desire, in fact, of the subject of desire. The place and meaning of the enigmatic third register in Lacan's thought, namely the 'real', is also addressed in relation to the question of desire. Furthermore, the question is raised, where philosophy in its traditional sense belongs – to the Lacanian register of the imaginary or to that of the symbolic. S. Afr. J. Philos. Vol.23(1) 2004: 1–19.

This collection of essays offers different ways of seeing twentieth-century art via the medium of aesthetics. Each essay explores a different vision: Pablo Picasso's Mercure , Paul Klee's work from the thirties, Yves Klein's concept of the Void, Ed Ruscha's gunpowder drawings, and Cy Twombly's Bacchus paintings. Having curated exhibitions on the majority of these artists, Olivier Berggruen's acquaintance with their work is profound, and his approach both scholarly and highly intimate. Olivier Berggruen lives in New York and (...) has curated museum exhibitions devoted to Pablo Picasso, Henri Matisse, Yves Klein, Jean-Michel Basquiat, and Ed Ruscha. (shrink)

" Se moquer de la philosophie, c'est vraiment philosopher. " Ce propos de Pascal, Olivier Bloch l'illustre et le confirme par le présent ouvrage, en s'attachant à démontrer la part de philosophie inhérente au texte de Molière et le jeu théâtral auquel elle renvoie. La philosophie, dont le terme et le concept courent tout au long de l'œuvre de Molière, c'est celle de son temps, au premier chef celle de Descartes, mais aussi les philosophies antagonistes comme celle de Gassendi. (...) L'étude d'Olivier Bloch nous montre que les pièces les plus célèbres de Molière - Dom Juan, Les Femmes Savantes, Tartuffe... comme d'autres moins connues - Amphitryon, Les Amants magnifiques... - mettent littéralement en scène des propos, des débats et des concepts caractéristiques de ces philosophies. Ce constat n'a rien d'anecdotique : nous découvrons ainsi que Molière avait une connaissance et une compréhension des problèmes philosophiques de son époque qui dépassent ce que l'on avait soupçonné jusqu'alors. Sur le registre de l'humour, il détourne à travers ses pièces les thèmes philosophiques majeurs de l'époque classique (Dieu et les preuves de son existence, l'âme et le corps, le Moi, etc.) et fait écho à leur mise en cause dans la Culture du XVIIe siècle. Lecture originale et subtile de Molière, cet essai éclaire son œuvre, les débats de son époque et les rapports qu'entretiennent la littérature, le théâtre, la comédie, le rire et la philosophie.

This chapter has three sections. The first introduces Brentano’s view of sensations by presenting the intentional features of sensations irreducible to features of the sensory objects. The second presents Brentano’s view of sensory objects —which include sensory qualities— and the features of sensations that such objects allow to explain, such as their intensity. The third section presents Brentano’s approach to sensory pleasures and pains, which combines both appeal to specific modes of reference and to specific sensory qualities.

Touch seems to enjoy some epistemic advantage over the other senses when it comes to attest to the reality of external objects. The question is not whether only what appears in tactile experiences is real. It is that only whether appears in tactile experiences feels real to the subject. In this chapter we first clarify how exactly the rather vague idea of an epistemic advantage of touch over the other senses should be interpreted. We then defend a “muscular thesis”, to (...) the effect that only the experience of resistance to our motor efforts, as it arises in effortful touch, presents us with the independent existence of some causally empowered object. We finally consider whether this muscular thesis applies to the perception of our own body. (shrink)

Dans cette question sur le livre II des Sentences, Guiral Ot demande si la créature, avant sa création, a un être propre, distinct de celui du Créateur : d’une part, Dieu crée ex nihilo ; avant la création, il n’y a donc rien, hormis Dieu ; d’autre part, Dieu connaît et veut de toute éternité ce qu’il produira avant de le produire ; les créatures ont bien un être-connu et un être-voulu en Dieu. Pour répondre à cette difficulté, Duns Scot (...) avait admis un être possible et un être relatif des créatures dans la pensée divine. Mais, avec plus de subtilité encore, Guiral Ot aperçoit neuf manières pour les choses d’être dans la pensée divine avant d’être créées. C’est le déploiement de ces modes d’être ainsi que leur articulation que nous révèle l’édition de cette question. (shrink)

Joan Copjec has shown that modernity is privy to a notion of immortality all its own – one that differs fundamentally from any counterpart entertained in Greek antiquity or the Christian Middle Ages. She points to Blumenberg and Lefort as thinkers who have construed this concept in its modern guise in different ways, and ultimately opts for Lefort's paradoxical understanding of immortality as the ‘transcending of time, within time' before elaborating on a corresponding notion in Lacan's work. It can be (...) shown that Nietzsche, too, provides a distinctly modern conception of ‘immortality', articulated in relation to his notions of affirmation, singularity and eternal recurrence. In brief, this amounts to his claim that, to affirm even one single part or event in one's life entails affirming it in its entirety, and, in so doing – given the interconnectedness of events – affirming all that has ever existed. Moreover, once anything has existed, it is in a certain sense, for Nietzsche, necessary despite its temporal singularity. Therefore, to be able to rise to the task of affirming certain actions or experiences in one's own life, bestows on it not merely this kind of necessary singularity, but what he thought of as ‘eternal recurrence' – the (ethical) affirmation of the desire to embrace one's own, and together with it, all of existence ‘eternally', over and over. This, it is argued, may be understood as Nietzsche's distinctive contribution to a specifically modern notion of immortality: the ability of an individual to live in such a way that his or her singular ‘place' in society is ensured, necessarily there, even after his or her death.

Augustin est le seul penseur antique à avoir rédigé un traité sur le concept d’image, la Question 74, où il démontre la possibilité d’une image (invisible) de l’invisible. Cette conception éclaire la réticence des Libri Carolini envers la théologie de l’icône, développée par le concile de Nicée II. La doctrine augustinienne de l’image mentale, associée au texte déchiffré, permet de comprendre la théorie médiévale de la méditation, et l’inflexion qu’elle subit en devenant « représentation » (Aelred de Reivaulx). Elle permet (...) enfin de justifier la doctrine de la vision face à face, contre l’invisibilité de Dieu dans l’au-delà, définie par Denys et Jean Scot, qui sera condamnée en 1241. (shrink)

Dans son œuvre théologique, Duns Scot propose une démonstration métaphysique de la Trinité. Il produit une véritable déduction a priori des émanations trinitaires, sans recourir aux données de l’Écriture, et antérieurement même aux noms des personnes. Puisqu’il n’existe que deux productions possibles, par mode d’intellection et par mode de volition, et parce qu’il faut partir d’une subsistence première, Duns Scot montre que l’essence divine, par le biais de la première personne, se communique nécessairement aux deux autres. Ce schéma fait l’économie (...) du Filioque hérité d’Augustin dans l’occident latin. Mais il y a un prix à payer : il est impossible de penser le passage de l’essence unitaire de Dieu à la triplicité des subsistences ; la réflexion se détache de l’Écriture sainte ; la théologie se sépare de l’économie du salut.
