When “divided attention” methods were discovered in the 1950s their implications for conscious experience were not widely appreciated. Yet when people process competing streams of sensory input they show both selective processesandclear contrasts between conscious and unconscious events. This paper suggests that the term “attention” may be best applied to theselection and maintenanceof conscious contents and distinguished from consciousness itself. This is consistent with common usage. The operational criteria for selective attention, defined in this way, are entirely different from those (...) used to assess consciousness. To illustrate the scientific usefulness of the distinction it is applied to Posner's brain model of visual attention. It seems that features that are often attributed to attention—like limited capacity—may more accurately be viewed as properties of consciousness. (shrink)

In humans, conscious perception and cognition depends upon the thalamocortical complex, which supports perception, explicit cognition, memory, language, planning, and strategic control. When parts of the T-C system are damaged or stimulated, corresponding effects are found on conscious contents and state, as assessed by reliable reports. In contrast, large regions like cerebellum and basal ganglia can be damaged without affecting conscious cognition directly. Functional brain recordings also show robust activity differences in cortex between experimentally matched conscious and unconscious events. This (...) basic anatomy and physiology is highly conserved in mammals and perhaps ancestral reptiles. While language is absent in other species, homologies in perception, memory, and motor cortex suggest that consciousness of one kind or another may be biologically fundamental and phylogenetically ancient. In humans we infer subjective experiences from behavioral and brain evidence. This evidence is quite similar in other mammals and perhaps some non-mammalian species. On the weight of the biological evidence, therefore, subjectivity may be conserved in species with human-like brains and behavior. (shrink)

Moral status is a vexing topic. Linked for so long to the unending debates about ensoulment and the morality of abortion, it has recently resurfaced in the embryonic stem cell controversy. In this new context, it should benefit from new insights originating in recent scientific advances. We believe that the recently observed capability of somatic cells to return to a pluripotential state (a capability we propose to name 'reversed potency') in a controlled manner requires us to modify the traditional concept (...) of moral status and to consider it as referring not only to intrinsic properties (like 'to possess reason' or 'to be a person'), but also to extrinsic or relational ones.

Collingwood’s account of re-enactment is often misunderstood as providing methodological guidance to historians. Williams’s chapter is perceptive in seeing through this erroneous interpretation. Williams is however very critical of Collingwood’s account of the relationship between philosophy and history. He reads Collingwood’s account of absolute presuppositions as embracing a form of ‘radical historicism’ and argues that, like many other philosophers who reject foundationalism, Collingwood tends to use the word ‘we’ in an evasive way, both in an inclusive sense “as implying universalistic (...) preconditions on interpretation and intelligibility” and in a contrastive sense “under which ‘we’ here and now are distinct from others elsewhere and elsewhen, who lived in others and different intelligible human formations”. William’s chapter appropriately introduces this volume since the question concerning the nature of absolute presuppositions, and in what sense they can be said to be constitutive of the forms of inquiry which they make possible, is a central concern of this collection and is discussed by several contributors.

Today most critical theorists who deploy history use a genealogical method forged by Nietzsche and Foucault. This genealogical approach now dominates historically inflected critique. But not all genealogical writings today, nor all philosophical debates surrounding genealogy, advance the goals of critical philosophy. It is crucial now that we assess the value of genealogical critiques. The proper metric against which to evaluate such work is whether it contributes to transforming ourselves, others, and society in a valuable way. In this article, I (...) propose that we use the term “critical genealogy” to identify those genealogical practices that positively nourish our activity and, thereby, advance the ambition of critical philosophy.

Since the advent of behaviorism the question of volition or "will" has been largely neglected. We consider evidence indicating that two identical behaviors may be quite distinct with respect to volition: For instance, with practice the details of predictable actions become less and less voluntary, even if the behavior itself does not visibly change. Likewise, people can voluntarily imitate involuntary slips they have just made. Such examples suggest that the concept of volition applies not to visible behavior per se, but (...) to the control system that guides behavior. Involuntary events include both automatisms and counter voluntary actions such as slips . An adequate theory of voluntary control must account for the entire set of such pairs of voluntary/involuntary contrasts. The problem of volition highlights core psychological issues. Voluntary acts are consistent with one′s current dominant goals. Volition and consciousness are intimately related. Consciousness of an action seems to recruit unconscious resources that help in planning, executing, and monitoring a voluntary act. Conversely, losing conscious access to an action seems to produce a loss of voluntary control. However, voluntary actions are not wholly conscious. It appears that we only need conscious access to nonroutine choice-points in the flow of control; routine aspects are handled unconsciously. The goals that guide voluntary acts often encounter conflict, either from reality or from other goals, and emotions are widely believed to result from appraisals of such conflicts . Finally, there is a close connection between countervoluntary slips and the symptoms of clinical pathology, which involve a loss of voluntary control over speech, action, feeling, imagery, or thought. A modern version of William James′ ideomotor theory is proposed, based on Global Workspace theory . The theory shows how a conscious goal image could activate unconscious plans and automatisms that shape a voluntary act. Conscious feedback from the act serves to communicate success or failure to many unconscious routines, which may then adapt cooperatively to shape future actions. (shrink)

Cet article étudie les principales classifications grecques anciennes des sciences mathématiques. Je souligne le rôle joué par Platon dans cette topique.

L’A. se propose un nouvel examen de l’unité du Phèdre, problème qui mobilise les commentateurs depuis l’Antiquité et a été récemment relancé dans les études françaises et anglo-américaines. De fait, Platon n’a pas explicité la charnière articulant le diptyque formé par le discours sur l’amour comme éros spiritualisé suivi de la réflexion sur la rhétorique du vrai. Au-delà de l’étrangeté formelle, l’enjeu est philosophique : la dualité même du dialogue signale la tentative platonicienne de maintenir à tout prix le travail (...) de la psychagogie, fondement de la recherche amoureuse de la vérité, sur le terrain de la parole politique, jusqu’à se heurter à l’éclatement mutuel des deux ordres. Reste alors, devant nos yeux, l’unité fracturée du métaphysique et du politique. (shrink)

Le polythéisme polynésien était-il une forme métaphorique de panthéisme ?

À suivre Gérard Genette, son passage de la critique littéraire à la poétique, puis de celle-ci à l’esthétique résulterait d’un « processus génétique en quelque sorte oblique », d’une « filiation collatérale » qui voit le détail d’un livre devenir le sujet du suivant. Un retour sur son parcours fait apparaître que l’enchaînement métonymique est lissé par le tuilage des moments : ceux-ci, pour être focalisés, n’en sont pas moins cumulatifs. Mieux, même, au fil du temps, dans la dynamique cumulative (...) d’un œuvre complet in progress, le principe de cohérence se sera appliqué non seulement à l’idéalité des textes, mais à la physicalité qui détermine le régime d’immanence de la littérature. On peut voir dans « Du texte à l’œuvre », « exercice d’autodiction préposthume » qui ouvre Figures IV, en 1997, plus que le simple bilan d’un chercheur, fût-il de grande envergure, dressant le bilan de son parcours au soir de sa carrière : sous couleur de rendre compte des liens qui unissent ses livres, il s’agit ni plus ni moins de montrer en quoi les textes qu’il a publiés constituent une œuvre.

Two main schemes explain how a system adapts to its environment. Evolutionary models are grounded on three usual processes (variation, transmission, selection) acting at the population level. Learning models are concerned with the endogenous search for a better performance at the individual level. The first ones were initially favored by biology and the second well illustrated by game theory. The article examines first how game theory went to evolution and how biology later considered learning. It shows some examples of a (...) hybrid use of models of each type. It finally proposes a common framework for both types of models. (shrink)

The 3rd batch of 6 books in this series on the Greatest Philosophers by acclaimed specialists writing for the General reader. From Aristotle to Wittgenstein, from Democritus to Derrida, this series provides a lucid and consise survey of philosophers ancient and modern. Each volume is by an acknowledged expert briefed to address the adventurous but non specialist reader.

Although women hold more negative attitudes toward cheating than do men, they are about as likely to engage in academic dishonesty. Cognitive dissonance theory predicts that this attitude-behavior inconsistency should lead women to experience more negative affect after cheating than would men. This prediction was tested in a sample of 92 male and 78 female college students who reported having cheated on an examination during the prior 6 months. Consistent with the results of previous research, women reported more negative attitudes (...) toward cheating than did men, but cheated at the same rate. However, women did not experience more negative affect than did men, although they reported experiencing less positive affect. The gender difference in positive affect was partially mediated by the gender difference in attitudes. (shrink)

This chapter contains sections titled: The Identity of Analytical Philosophy Meta‐ethics Ethical Theory Morality, Politics and Analytical Philosophy.

Block seems to propose untested answers to empirical questions. Whether consciousness is a “mongrel problem,” rather than a single core fact with many facets, is an empirical issue. Likewise, the intimate relationship between personal consciousness and global access functions cannot be decided pretheoretically. This point is demonstrated by the reader's private experience of foveal versus parafoveal vision, and for conscious versus unconscious representation of the many meanings of common words.

Sociobiologists claim that there are important constraints on human behavior that are the result of genetic factors. Some of them also claim that this has important implications for ethics, and even more generally for determining how persons ought to behave. In this paper I shall defend these two claims, though I shall not be defending the views of any particular sociobiologist, unless one is prepared to count Hobbes as a sociobiologist.

A summary is out of place because of the outlinish nature of the presentation. I have presented a taxonomy or general theory of ethics. The view is acceptable or not depending on how well it competes with rival theories. One thing that hinders such a comparison is the absence of sufficiently clearly articulated rivals. Perhaps this paper will stimulate the production of some rival views.

This study is based on the self-reporting by circus artists’ concerning their injuries. We refer to the theoretical framework of emersiology and argue that circus artists may be able to soothe their distress and pain by learning through their body. We will draw further on the comparison between our therapeutic approach and the techniques of self-care introduced by Michel Foucault in his History of Sexuality.

This article analyses neuronal determinism and mentions that at first sight it appears to be a type of qualified determinism. Neurodeterminism is better conceived as determinism tout court when it is applied to human beings. It differs importantly from genetic determinism, together the two views that are often regarded as similar in form if not in content. Moreover, the article examines the question of genetic determinism, because it is a paradigm of qualified determinism. It then explains the meaning of determinism (...) tout court, its relation with the notions of “free will” and “responsibility,” and the debate about their alleged incompatibility. It provides an understanding of what neurodeterminism consists of, shows that it should be conceived as determinism tout court when it is applied to human beings, imparting an empirical turn to a very old metaphysical conundrum.

Moral psychology is often ignored in ethical theory, making applied ethics difficult to achieve in practice. This is particularly true in the new field of animal ethics. One key feature of moral psychology is recognition of the moral primacy of those with whom we enjoy relationships of love and friendship – philia in Aristotles term. Although a radically new ethic for animal treatment is emerging in society, its full expression is severely limited by our exploitative uses of animals. At this (...) historical moment, only the animals with whom we enjoy philia – companion animals – can be treated with unrestricted moral concern. This ought to be accomplished, both for its own sake and as an ideal model for the future evolution of animal ethics. (shrink)

Surgical patients under anesthesia can wake up unpredictably and be exposed to intense, traumatic pain. Current medical techniques cannot maintain depth of anesthesia at a perfectly stable and safe level; the depth of unconsciousness may change from moment to moment. Without an effective consciousness monitor anesthesiologists may not be able to adjust dosages in time to protect patients from pain. An estimated 40,000 to 200,000 midoperative awakenings may occur in the United States annually. E. R. John and coauthors present the (...) scientific basis of a practical ''consciousness monitor'' in two articles. One article is empirical and shows widespread and consistent electrical field changes across subjects and anesthetic agents as soon as consciousness is lost; these changes reverse when consciousness is regained afterward. These findings form the basis of a surgical consciousness monitor that recently received approval from the U.S. Food and Drug Administration. This may be the first practical application of research on the brain basis of consciousness. The other John article suggests theoretical explanations at three levels, a neurophysiological account of anesthesia, a neural dynamic account of conscious and unconscious states, and an integrative field theory. Of these, the neurophysiology is the best understood. Neural dynamics is evolving rapidly, with several alternative points of view. The field theory sketched here is the most novel and controversial.
