Chacun d'entre nous fait partie du monde, certes. Mais, au-delà de son évidence, quelle est la signification d'une telle formule? Comment faisons-nous partie du monde? Comment sommes-nous reliés à tout ce qui n'est pas nous : les autres, le reste de la nature, le cosmos? Lionel Naccache répond à cette énigme intemporelle à partir d'une approche mathématique fondée sur la distinction entre ensembles discrets et ensembles continus : alors qu'un élément, qui fait partie d'un ensemble discret, reste séparé (...) des autres éléments par des frontières tranchées, ces frontières disparaissent dans un ensemble continu. La question devient alors : sommes-nous reliés au reste du monde par des liens continus ou par des liens discrets? Muni de cette boussole, Lionel Naccache nous propose une odyssée passionnante et pleine de gai savoir éclectique qui nous entraîne de la psychologie de la subjectivité vers les sciences du cerveau et de la conscience, les origines et l'évolution des idées mathématiques et la philosophie politique. Au bout du voyage, Lionel Naccache formule une nouvelle éthique pour le XXIe siècle"--Page 4 of cover. (shrink)

Can we ever experimentally disentangle phenomenal consciousness from the cognitive accessibility inherent to conscious reports? In this commentary, we suggest that (1) Block's notion of phenomenal consciousness remains intractably entangled with the need to obtain subjective reports about it; and (2) many experimental paradigms suggest that the intuitive notion of a rich but non-reportable phenomenal world is, to a large extent illusory – in a sense that requires clarification.

This introductory chapter attempts to clarify the philosophical, empirical, and theoretical bases on which a cognitive neuroscience approach to consciousness can be founded. We isolate three major empirical observations that any theory of consciousness should incorporate, namely (1) a considerable amount of processing is possible without consciousness, (2) attention is a prerequisite of consciousness, and (3) consciousness is required for some specific cognitive tasks, including those that require durable information maintenance, novel combinations of operations, or the spontaneous generation of intentional (...) behavior. We then propose a theoretical framework that synthesizes those facts: the hypothesis of a global neuronal workspace. This framework postulates that, at any given time, many modular cerebral networks are active in parallel and process information in an unconscious manner. An information becomes conscious, however, if the neural population that represents it is mobilized by top-down attentional amplification into a brain-scale state of coherent activity that involves many neurons distributed throughout the brain. The long-distance connectivity of these `workspace neurons' can, when they are active for a minimal duration, make the information available to a variety of processes including perceptual categorization, long-term memorization, evaluation, and intentional action. We postulate that this global availability of information through the workspace is what we subjectively experience as a conscious state. A complete theory of consciousness should explain why some cognitive and cerebral representations can be permanently or temporarily inaccessible to consciousness, what is the range of possible conscious contents, how they map onto specific cerebral circuits, and whether a generic neuronal mechanism underlies all of them. We confront the workspace model with those issues and identify novel experimental predictions. Neurophysiological, anatomical, and brain-imaging data strongly argue for a major role of prefrontal cortex, anterior cingulate, and the areas that connect to them, in creating the postulated brain-scale workspace.

Amidst the many brain events evoked by a visual stimulus, which are specifically associated with conscious perception, and which merely reflect non-conscious processing? Several recent neuroimaging studies have contrasted conscious and non-conscious visual processing, but their results appear inconsistent. Some support a correlation of conscious perception with early occipital events, others with late parieto-frontal activity. Here we attempt to make sense of those dissenting results. On the basis of a minimal neuro-computational model, the global neuronal workspace hypothesis, we propose a (...) taxonomy which distinguishes between vigilance and access to conscious report, as well as between subliminal, preconscious and conscious processing. We suggest that these distinctions map onto different neural mechanisms, and that conscious perception is systematically associated with a sudden surge of parieto-frontal activity causing top-down amplification.

The revisionary approach to semantic paradox is commonly thought to have a somewhat uncomfortable corollary, viz. that, on pain of triviality, we cannot affirm that all valid arguments preserve truth (Beall2007, Beall2009, Field2008, Field2009). We show that the standard arguments for this conclusion all break down once (i) the structural rule of contraction is restricted and (ii) how the premises can be aggregated---so that they can be said to jointly entail a given conclusion---is appropriately understood. In addition, we briefly rehearse (...) some reasons for restricting structural contraction. (shrink)

En affirmant que "tout philosophe a deux philosophies : la sienne et celle de Spinoza", Bergson exprime avant tout que le philosophe se doit de rompre avec une pensée dogmatique qui n'a plus lieu d'être et que Spinoza incarne tout particulièrement. Le spinozisme manifeste la pente de l'intelligence lorsqu'elle suit sa logique propre sans être rectifiée par le recours à l'expérience. Or, c'est cette démarche systématique que la philosophie doit désormais abandonner. Bergson est néanmoins hanté par la pensée de Spinoza (...) et le rapport qu'il entretient avec lui, en particulier dans ses cours au Collège de France, met en évidence un lien bien plus complexe et subtil qu'un simple rapport d'opposition. Contre la tendance à la clôture et à la systématicité, Bergson va alors privilégier chez Spinoza la tendance à l'ouverture et au mysticisme. En mettant en lumière cet aspect, cet ouvrage montre la sympathie intellectuelle qui réunit ces penseurs autour des notions de joie et de liberté. C'est pourquoi la figure du Christ va constituer un modèle non seulement éthique mais ontologique. Le terme de mysticisme, chez ces deux auteurs, ne désigne ni le refus de l'expérience ni celui des sciences positives mais renvoie à un rationalisme élargi jusqu'à l'amour du réel."--Page 4 of cover.

This book presents an approach to spirituality based on direct personal experience of the sacred. Using the language and insights of depth psychology, Corbett outlines the intimate relationship between spiritual experience and the psychology of the individual, unveiling the seamless continuity between the personal and transpersonal dimensions of the psyche. His discussion runs the gamut of spiritual concerns, from the problem of evil to the riddle of pain and suffering. Drawing upon his psychotherapeutic practice as well as on the experiences (...) of characters from our religious heritage, Corbett explores the various portals through which the sacred presents itself to us: dreams, visions, nature, the body, relationships, psychopathology, and creative work. Referring extensively to Jung's writings on religion, but also to contemporary psychoanalytic theory, Corbett gives form to the new spirituality that is emerging alongside the world's great religious traditions. For those seeking alternative forms of spirituality beyond the Judeo-Christian tradition, this volume will be a useful guide on the journey. (shrink)

Tout a commencé comme une enquête classique, avec l'espoir de déterminer ce que le nom " contemporain " dit de notre rapport au temps, à l'histoire, à l'espace. Mais très vite des myriades de données, parfois contradictoires, se sont imposées. Un véritable brouhaha. On aurait pu les ignorer, faire comme si elles n'existaient pas, et tenter de construire une fiction unitaire qui aurait prétendu dire la totalité de notre identité historique. C'eut été se méprendre sur la dynamique profonde que traduit (...) le nom contemporain. Elle se déploie ainsi : la représentation moderne du monde est débordée de toutes parts par une multiplicité qu'elle ne peut plus contenir, et qui la fait apparaître pour ce qu'elle est : un imaginaire, une illusion ; imaginaire de la distinction, de la séparation, alors que le contemporain propose, lui, un imaginaire marqué par l'indistinction, la déhiérarchisation, la globalisation. Toutes les histoires documentées dans cet essai retrouvent ce mouvement. Ainsi des espaces publics de l'art qui voient la fin du dispositifinstitution musée d'art moderne au profit des centres d'art contemporain et évoquent par là une manière différente d'habiter le monde. Ainsi du très grand nombre qui ne se laisse plus discipliner dans les concepts politiques hérités de la modernité. D'autres émergent (multitude, publics), prenant mieux en compte la double poussée de la massification et de la différenciation. Ainsi de la production du savoir qui se décentre et s'horizontalise. Ainsi du temps vécu comme une concordance de temporalités à l'ère hypermédiatique. Ainsi de l'imaginaire littéraire, emblématique de la modernité et lié au support-livre, qui intègre un plus vaste régime de publication. Ainsi de la pensée du monde qui est désormais une pensée des mondes. En six stations qui sont autant de mots-clés du contemporain (exposition, médias, controverses, publication, institutionnalisation, archéologie), cet essai s'attache à décrire les transformations actuelles des formes culturelles et des visions de l'histoire.

ABSTRACT:‘Race’ has long searched for a stable, suitable idea, with no consensus on a master meaning in sight. What I call deflationary pluralism about the existence of race recognizes that various meanings may be true as far as they go but avoids murky disputes over whether there are races in some sense. Once we have rejected the notion that racial essences yield innate cognitive differences, there is little point to arguing over the race idea. In its place, I propose the (...) idea of socioancestry, which jettisons racial thinking yet recognizes the social dynamics of color. For example, Black Americans, many of whom have traceable non-African ancestry, constitute an Africa-identified, socioancestrally black subgroup. ‘Race’ talk is not needed to sustain legitimate color-conscious approaches to social identity and social justice. Long-standing fixation on the race idea has obscured the simple truth that visible continental ancestry is the root of the social reality of color consciousness. (shrink)

The lexicon of religion has been widely used in the context of the social and cultural transformations associated with the ‘digital revolution’, whether in metaphoric or in realistic terms. The study of digital magic/magic in digital times, the other side of the coin of the Sacred 2.0, is still in its infancy. Yet, references to magic are made frequently in reflections about the rapid development of the digitalisation of society and culture, and they deserve more in-depth study. This paper tackles (...) the issue of magic in and of new technologies, including artificial intelligence devices. After a broad outline of the presence of magic in the digital ecosystem, this paper will focus on the lexical surface and semantic references to ‘magical thinking’, explore the underlying reasons for such references and unveil the regimes of existence for magic. Finally, the paper questions the role of language in the construction of a ‘digital magic’ and the transformations of the semantic category of magic as seen through the prism of a cultural revolution, that of the digitalisation of societies.

Building on recent work, I present sequent systems for the non-classical logics LP, K3, and FDE with two main virtues. First, derivations closely resemble those in standard Gentzen-style systems. Second, the systems can be obtained by reformulating a classical system using nonstandard sequent structure and simply removing certain structural rules (relatives of exchange and contraction). I clarify two senses in which these logics count as “substructural.”.

Development of the shapes of living organisms and their parts is a field of science in which there are no generally accepted theoretical principles. What form these principles are likely to take, when they emerge, is a subject in which there is a wide gulf of disagreement between physical scientists and experimental biologists. This book contains both an extensive philosophical commentary on this dichotomy in views and an exposition of the type of theory most favoured by physical scientists. In this (...) theory living form is a manifestation of the dynamics of chemical change and physical transport or other physics of spatial communication. The reaction-diffusion theory, as initiated by Turing in 1952 and since elaborated by Prigogine and by Gierer and Meinhardt among others, is discussed in detail at a level that requires a good knowledge of a first course in calculus, but no more than that. The great growth of molecular biology has tended to overshadow the increase in our understanding of the nature of these kinetic processes. This book seeks to reawaken interest in dynamics in the hope that a better balance between the importance of things and the importance of actions may emerge in the biology of the 21st century.

Deflationists about truth seek to undermine debates about the nature of truth by arguing that the truth predicate is merely a device that allows us to express a certain kind of generality. I argue that a parallel approach is available in the case of logical consequence. Just as deflationism about truth offers an alternative to accounts of truth's nature in terms of correspondence or justification, deflationism about consequence promises an alternative to model-theoretic or proof-theoretic accounts of consequence's nature. I then (...) argue, against considerations put forward by Field and Beall, that Curry's paradox no more rules out deflationism about consequence than the liar paradox rules out deflationism about truth.

Innocence is a notion that can prove controversial. Claims of innocence typically support not imposing burdens on the innocent when their conduct is relevantly unobjectionable. This paper examines innocence in the context of violent conflict between states or groups. Many thinkers about the morality of such violence want to establish a principle that would protect innocent civilians. Yet the common view in just war theory does not affirm the moral innocence of civilians. Similarly, the common view that soldiers have an (...) equal right to kill does not affirm their equal moral culpability. (shrink)

According to commitment accounts of assertion, asserting is committing oneself to something’s being the case, where such commitment is understood in terms of norms governing a social practice. I elaborate and compare two version of such accounts, liability accounts (associated with C.S. Peirce) and dialectical norm accounts (associated with Robert Brandom), concluding that the latter are more defensible. I argue that both versions of commitment account possess a potential advantage over rival normative accounts of assertion in that they needn’t presuppose (...) any notion of an assertion’s correctness. Additionally, I show how dialectical norm accounts can explain relations between assertion and truth. After setting forth objections that have been raised against commitment accounts, I argue that responses are available on behalf of dialectical norm accounts. Finally, I propose that a liberalized dialectical norm account can illuminate phenomena sometimes seen as supporting truth relativism. (shrink)

Experiencing a stimulus in one sensory modality is often associated with an experience in another sensory modality. For instance, seeing a lemon might produce a sensation of sourness. This might indicate some kind of cross-modal correspondence between vision and gustation. The aim of the current study was to provide explore whether such cross-modal correspondences influence cross-modal integration during perceptual learning. To that end, we conducted 2 experiments. Using a speeded classification task, Experiment 1 established a cross-modal correspondence between visual lightness (...) and the frequency of an auditory tone. Using a short-term priming procedure, Experiment 2 showed that manipulation of such cross-modal correspondences led to the creation of a crossmodal unit regardless of the nature of the correspondence (i.e., congruent, Experiment 2a or incongruent, Experiment 2b). However, a comparison of priming-effects sizes suggested that cross-modal correspondences modulate cross-modal integration during learning and thus leading to new learned units that have different stability over time. We discuss the implications of our results for the relation between cross-modal correspondence and perceptual learning in the context of a Bayesian explanation of cross-modal correspondences.

Rejecting structural contraction has been proposed as a strategy for escaping semantic paradoxes. The challenge for its advocates has been to make intuitive sense of how contraction might fail. I offer a way of doing so, based on a “naive” interpretation of the relation between structure and logical vocabulary in a sequent proof system. The naive interpretation of structure motivates the most common way of blaming Curry-style paradoxes on illicit contraction. By contrast, the naive interpretation will not as easily motivate (...) one recent noncontractive approach to the Liar paradox. (shrink)
