Subjects classified visible 2-digit numbers as larger or smaller than 55. Target numbers were preceded by masked 2-digit primes that were either congruent (same relation to 55) or incongruent. Experiments 1 and 2 showed prime congruency effects for stimuli never included in the set of classified visible targets, indicating subliminal priming based on long-term semantic memory. Experiments 2 and 3 went further to demonstrate paradoxical unconscious priming effects resulting from task context. For example, after repeated practice classifying 73 as larger (...) than 55, the novel masked prime 37 paradoxically facilitated the “larger” response. In these experiments task context could induce subjects to unconsciously process only the leftmost masked prime digit, only the rightmost digit, or both independently. Across 3 experiments, subliminal priming was governed by both task context and long-term semantic memory. (shrink)

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)

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.

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 article contributes to the general literature on the relationship between corporate social performance and corporate financial performance, as well as to the emerging HRM–CSR literature, by exploring the curvature of the relationship between HRM–CSP and CFP. We advance conceptual arguments in favor of an inverted U-shaped relationship. Our results demonstrate a significant quadratic relationship between HRM–CSP and CFP. We provide evidence that this relationship is not linear or S-shaped but rather inverted U-shaped.

This paper presents a non-reductionist framework of eight nested modes of evolution that have successively emerged to organize the reproduction of all organisms, from the blue-green algae to our societies. The processes of biological, "Darwinian," evolution are those of drift during reproduction, and of selection. The key unit of evolutionary time is the generation, and its locus is the organisms' life-cycle setup. Different life-cycle setups support different mechanisms of reproduction, and therefore different modes of evolution. By tracing the different life-cycle (...) setups attested throughout Life's History, we are able to characterize the successive modes of evolution with which they are associated. The present attempt has led to a characterization of the following eight nested modes of evolution: Basic; Reptilian; Archaic Mammalian; Progressive Mammalian; Socio-cultural; Extrasomatically Enhanced Socio-cultural; Tinkering; and finally Para-biological. These successively emerging modes govern a progressively reduced number of life-forms. The first four modes are "Darwinian" in the strict sense. The fifth, or socio-cultural mode, which governs whale and elephant societies in addition to hominoids, is already not "Darwinian" in the traditional sense. The last three modes have emerged with the genus homo, through the progressive extension of its life-cycle setups. The present framework is to be used heuristically, as a prism with which to separate the evolutionary spectrum of the constituent elements of human behavior. An example of such a behavioral evolutionary spectrum is presented in the conclusion, and is used to compare the present framework with those recently proposed by Maynard Smith and Szathmáry and by Foley.

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.

L. Nathan Oaklander is one of the leading philosophers of time defending the tenseless or B-Theory of time. He has remained at the forefront of this field since the early 1980s and today he is arguably the most formidable opponent of the tensed or A-theory of time. Much of the direction of the debate in this field for the past twenty years or so, especially in regards to the new tenseless theory of time, has been influenced by Oaklander's work. This (...) book presents a carefully argued defense of the tenseless theory of time. The topics discussed include: the ontology of A- and B-theories of time; presentism; the open future theory; the A/B theory; defending the B-theory of time; temporal experience; temporal semantics; and time, identity, responsibility, and freedom.

Edmund Gettier is Professor Emeritus at the University of Massachusetts, Amherst. This short piece, published in 1963, seemed to many decisively to refute an otherwise attractive analysis of knowledge. It stimulated a renewed effort, still ongoing, to clarify exactly what knowledge comprises.

This new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology.

This edited volume represents a unique addition to the available literature on animal ethics, animal studies, and neuroethics. Its goal is to expand discussions on animal ethics and neuroethics by weaving together different threads: philosophy of mind and animal minds, neuroscientific study of animal minds, and animal ethics. Neuroethical questions concerning animals’ moral status, animal minds and consciousness, animal pain, and the adequacy of animal models for neuropsychiatric disease have long been topics of debate in philosophy and ethics, and more (...) recently also in neuroscientific research. The book presents a transdisciplinary blend of voices, underscoring different perspectives on the broad questions of how neuroscience can contribute to our understanding of nonhuman minds, and on debates over the moral status of nonhuman animals. All chapters were written by outstanding scholars in philosophy, neuroscience, animal behavior, biology, neuroethics, and bioethics, and cover a range of issues and species/taxa. Given its scope, the book will appeal to scientists and students interested in the debate on animal ethics, while also offering an important resource for future researchers.

Le philosophe Jean Baudrillard (1929-2007) a-t-il vraiment existé? Que reste-t-il de lui? "Une élégance certaine de la pensée", affirme l'un de ses meilleurs interprètes, François L'Yvonnet. Le philosophe de La Société de consommation, des Stratégies fatales et des Cool Memories s'attachait à l'idée du fragment comme mode de pensée : car dans le détail, tout est parfait, c'est dans sa reproduction que tout se complique. François L'Yvonnet explore cinq fragments de la philosophie de Jean Baudrillard et de sa biographie pour (...) mieux saisir l'éclat et la jubilation d'une pensée toujours vivante et contemporaine.

Excerpt from Der Echte: Und der Xenophontische Sokrates Der xen0phontische Sokrates selbst wieder zwang, die Fuh rung der Untersuchung weit mehr, als bisher geschehen, zu ver breitem. Die Memorabilien sind das Gegentheil eines selbst herrlichen Kunstwerks, weisen an allen Ecken und Enden uber sich hinaus, stehen als ein schwaches Glied in der Kette der sokratischen Literatur und zunachst in der der xenophontischen Schriften. Es galt, sie zunachst als solches zu begreifen und das volle Licht der Parallelen bei Xenophon auf sie (...) einwirken zu lassen. Dabei enthullten sich die Mem. Oft nur als durftiger Abklatsch anderer xenophontischen Schriften, von denen sie erst die farbige Beleuchtung, die Erklarung ihrer Motive, die Auf hellung ihrer Ordnung erhalten. So ward nun moglichst psycho logisch aus Xenophon erklart, was sich aus ihm erklaren liess. Indessen fur die Hauptsache, das Philosophische, stellte Xeno phon's notorische Unselbstandigkeit neue Fragen und Aufgaben, und hier ergab nun eine weitschichtige Vergleichung seine fast vollige philosophische Abhangigkeit im Ganzen wie im Einzelnen vom Kynismus, die in Grad und Art und plausiblen Motiven genau der Abhangigkeit der romischen Praktiker von den stoischen Nachfolgern der Kyniker_ entspricht. Nicht nur die Memorabilien, auch die andern Socratica Xenophon's, sowie vor Allem Cyropadie Hiero Agesilaus, de rep. Lac. Prolog und Epilog des Oynegeticus offenbarten sich mehr und mehr als durchaus kynisirende Schriften, und auch hier liegt dem Verf.

Ingthorsson, McTaggart’s Paradox and the R-theory of Time L. Nathan Oaklander University of Michigan-Flint, USA [email protected] his provocative book, McTaggart’s Paradox, R.D. Ingthors- son argues that McTaggart’s argument for the unreality of time rests on the principle of temporal parity according to which all times or events in time exist equally or co-exist in a sense that is compatible with their being successive. Moreover, since temporal parity is also an essential tenet of the B-theory, McTaggart’s argument against the reality of (...) time can also be used to undermine the B-theory. Ingthorsson argues further that only by adopting an ontologically frugal presentist metaphysics can one avoid McTaggart’s paradox and account for identity through time and change. The aim of this paper is to clarify Russell’s authentic view of time in con- trast to the B-theory which is McTaggart’s misrepresentation of Russell and argue that temporal parity it is not a fundamental tenet of the Rus- sellian theory. For that reason, the R-theory is immune to objections that are based on temporal parity. I shall then offer my own interpretation of McTaggart’s paradox that renders Ingthorsson’s version of presentism subject to it. (shrink)

En une petite centaine de pages, l'auteur éclaire l'œuvre de Simone Weil avec des facettes emblématiques de sa biographie : une cartographie des lieux et des influences, la question du déracinement, son rapport à la judaïté.

What is the nature of temporal passage—the movement of events or moments of time from the future through the present into the past? Is the future and the past as real as the present, or is the present—or perhaps the present and the past—all that exists? What role, if any, does language play in giving us an insight into temporal reality? Is it possible to travel through time into distant regions of the future or the past? What accounts for the (...) direction of time, the sense we have that we are moving toward the future and not back into the past? What is the relation between the physics of time and the philosophy of time? These are the kind of dizzying questions that have been addressed by metaphysicians since antiquity, and time has remained a critical concept for many thinkers and philosophers since then (for instance, in his Confessions, St Augustine, restating an observation by Plotinus, wrote: ‘So what is time? If no one asks me, I know; if I seek to explain it, I do not’). Interest in the subject has also been enduring—and has blossomed anew in the past century. The Philosophy of Time is a new title in the Routledge series, Critical Concepts in Philosophy. It meets the need for an authoritative reference work to make sense of the subject’s vast literature and the continuing explosion in research output. Edited by L. Nathan Oaklander, a leading scholar in the philosophy of time, this new Major Work from Routledge brings together in four volumes the canonical and the very best cutting-edge scholarship in the field to provide a synoptic view of all the key issues and current debates. With a comprehensive introduction to the collection, newly written by the editor, which places the collected material in its historical and intellectual context, The Philosophy of Time is an essential work of reference and is destined to be valued by philosophers of time—as well as those working in related areas of philosophy of science, philosophy of mind, and philosophy of religion—as a vital research resource.
