A breathtaking look at the new science that can track consciousness deep in the brain How does our brain generate a conscious thought? And why does so much of our knowledge remain unconscious? Thanks to clever psychological and brain-imaging experiments, scientists are closer to cracking this mystery than ever before. In this lively book, Stanislas Dehaene describes the pioneering work his lab and the labs of other cognitive neuroscientists worldwide have accomplished in defining, testing, and explaining the brain events (...) behind a conscious state. We can now pin down the neurons that fire when a person reports becoming aware of a piece of information and understand the crucial role unconscious computations play in how we make decisions. The emerging theory enables a test of consciousness in animals, babies, and those with severe brain injuries. A joyous exploration of the mind and its thrilling complexities, Consciousness and the Brain will excite anyone interested in cutting-edge science and technology and the vast philosophical, personal, and ethical implications of finally quantifying consciousness.

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.

There are two opposing views concerning intuitive cases of wage exploitation. The first denies that they are cases of exploitation at all. It is based on the nonworseness claim: there is nothing wrong with a discretionary mutually beneficial employment relationship. The second is the reasonable view: some employment relationships can be exploitative even if employers have no duty towards their employees. This article argues that the reasonable view does not completely defeat defences of wage exploitation, because these do not rely (...) solely on the nonworseness claim. They also rely on the idea, popularised by Alan Wertheimer, that exploitation is a form of disequilibrium price occurring in defective markets. The article then proceeds to criticise Wertheimer’s account through neoclassical, new institutional, and Austrian economics. It concludes that considerations for economic efficiency are irrelevant to assessing intuitions regarding exploitation. (shrink)

In the first English language translation of this classic late 20th-century text within French Catholic thought, Poetics of the Sensible brings together insights from Neoplatonism and phenomenology with a distinctive and innovative approach. Taking a stance within the generative conception of human language represented by continental thinkers such as Humboldt and Herder and powerfully articulated today by Charles Taylor, Stanislas Breton expands the sense of the "poetic"-the constructive meaning-bearing capacity that is a core characteristic of humanity-to include the body (...) and its senses phenomenologically intertwined with the world. Defying Heidegger's prohibition on the question of God alongside contemporary thinkers such as Jean-Luc Marion, Jean-Louis Chrétien and Emmanuel Falque, he boldly writes of God, of the angel, of the icon, and of prayer in a refusal to bracket his religious faith. Against a Neoplatonic backdrop, Breton promotes the dense material dimensions of embodied signification as paradoxically harbouring meaning that is greater than that of conceptual abstraction alone. Illuminating Breton's poetic and allusive discourse, Poetics of the Sensible showcases his unique voice in French philosophy, phenomenology and the philosophy of religion and is essential reading for scholars and students alike.

La connaissances noyau de la géométrie euclidienne est liée au raisonnement déductif et non à la reconnaissance de motifs perceptuels.

"La méditation du Principe est le principe même de la philosophie." Cette sentence par laquelle débute le présent ouvrage ne décline pas seulement le projet d'un livre, elle traduit l'ambition d'une oeuvre. Son auteur, Stanislas Breton, disparu le 2 avril 2005, métaphysicien original et génial, parvenu alors au faîte d'une recherche initiée dans les universités romaines, poursuivie dans les Instituts catholiques de Lyon de Paris et relancée à l'Ecole normale supérieure d'Ulm, en déroulait alors la thèse dans une étonnante (...) fulgurance. Trente ans exactement après sa première publication, celle-ci se trouve à nouveau, plus actuelle que jamais, présentée au public. Les quatre parties qui la structurent sont consacrées au concept antique de "Principe" à "l'Ineffable" auquel il se trouve nécessairement confronté, à ses usages en philosophie et en théologie, et à la critique à laquelle le soumet la pensée contemporaine. Elles déchiffrent, chemin faisant, ce qui décide, sous des modes bien différents, de l'"organisation du pensable" à l'intérieur des philosophies et des théologies. Ainsi réédité, cet ouvrage se livre à l'inspiration de nouvelles générations soucieuses d'honorer et d'exploiter, dans la ligne du N Fonds Breton une oeuvre d'exception. (shrink)

Cet essai est un retour aussi réfléchi que possible sur l'ensemble de mes écrits de philosophie. S'étalant sur une durée approximative de cinquante-cinq ans, ils sont à la fois nombreux et, du fait de leur nombre, menacés par la dispersion. Je suis bien conscient de l'objection possible ainsi que de la demande, toujours plus réitérée depuis 1990, d'une quasi-synthèse, de la part de lecteurs qui, à diverses reprises, m'ont fait part de leur sympathie et de leur encouragement. Je me suis (...) promis de les satisfaire par un bref écrit qui serait, à ma façon, et sans égaler le modèle qui de loin m'inspire, une quasi-monadologie. J'ai le sentiment, dans ce retour sur mon passé, de devoir beaucoup à ceux qui, au cours de mon cheminement, m'ont aidé dans ce long travail de pensée. Ma première interrogation serait donc celle-ci : " Qu'as-tu que tu n'aies reçu? STANISLAS BRETON. (shrink)

Stanislas Breton's _A Radical Philosophy of Saint Paul_, which focuses on the political implications of the apostle's writings, was an instrumental text in Continental philosophy's contemporary "turn to religion." Reading Paul's work against modern thought and history, Breton helped launch a reassessment of Marxism, introduce secular interpretations of biblical and theological traditions, develop "radical negativity" as a critical category, and rework modern political ideas through a theoretical lens. Newly translated and critically situated, this edition takes a fresh approach to (...) Breton's classic work, reacquainting readers with the remarkable ways in which an ancient apostle can reset our understanding of the political. Breton begins with Paul's biography and the texts of his conversion, which challenge common conceptions of identity. He broaches the question of allegory and divine predestination, introduces the idea of subjectivity as an effect of power, and confronts Paul's critique of Law, which leads to an exploration of the logics and limits of agency and power. Breton develops these and other insights in relation to Paul's subversive reflections on the crucified messiah, which challenge meaning and reason and upend our current world order. Neither a coherent theologian nor a stable humanist, Breton's Paul becomes a fascinating figure of excess and madness, experiencing a kind of being that transcends philosophy, secularity, and religion.

Sean Irving’s book Hayek’s Market Republicanism: The Limits of Liberty shows that the commonly accepted reading of Hayek as a liberal thinker is mistaken, and that his political writings are best understood as belonging to the broader tradition of republicanism. The distinction is important for understanding many aspects of Hayek’s thought, and especially his rejection of social justice and majoritarian democracy. In that sense, one of the book’s more general merits is its implicit contribution to ongoing debates between republican ‘freedom (...) as non-domination’ and liberal ‘freedom as non-interference’. Irving focuses on what he sees as a contradiction between Hayek’s chief concerns about the state as the main source of domination and his disregard for private forms of power, and especially within the capitalist firm. I argue, however, that the example of Hayek should lead us to consider a more prosaic conclusion: freedom as non-domination is a concept less useful for criticising the free market than Irving and left-leaning Republicans seem to assume.

The charism of the congregation expresses some selected and implemented aspect of the mystery of Christ and the life of the Church, and its specificity is the determinant of the identity of the institute. From it follows a specific pattern of relationship with God and with the environment, the characteristics of spirituality, various forms of the practice of the evangelical counsels, business forms and certificates of members, leading to the formation of a particular tradition. An important dimension in the formation (...) and development of religious congregations are the socio-cultural conditions. In business meetings is visible specific aspect resulting from its own charisma, but its implementation are multiple activities forming an integral approach to the needs of people and the environment. Thanks to the dynamics of dialogue educational activities, organizational and social formed in the nineteenth/twentieth century in Poland, active congregations today continues and is still valid.

This paper clarifies the usage of Albert Hirschman’s categories of market behaviour as of exit and voice in debates about workplace democracy by taking seriously his critique of the neoclassical analysis of competition. Pro-market liberals are generally hostile to the idea of workplace democracy and tend to favour top-down hierarchies as a way of organising labour. This hostility is generally inspired by the neoclassical analysis of exploitation and efficiency, which leads them to defend distributions achieved through exit-based competitive equilibria. Following (...) Hirschman, I propose to consider a hypothetical alternative: a democratic equilibrium, reached through the use of voice. I show that it would present the same appealing characteristics than its competitive counterpart while also accounting for the non-ideal conditions in which markets operate. Support for free markets should entail support for workplace democracy minimally understood as a strengthening of voice. (shrink)

Comment penser et décrire l'animal aujourd'hui? Faut-il insister sur l'identité homme-animal, au point de supprimer toute différence? Doit-on maintenir un propre de l'homme, et si oui, lequel? Comment éviter les travers de l'anthropocentrisme? Que faire - et ne pas faire - aux animaux, et au nom de quoi? Georges Chapouthier et Florence Burgat travaillent depuis longtemps ces questions, d'une manière qui déplace nos (pré)conceptions...

A prominent defence of compulsory voting is based on the negative effects of a low turnout on democracy, which leads to an unequal representation of the most vulnerable citizens of our societies, since they are the least likely to vote voluntarily. This paper shows that this justification relies on the truth of an added premise – that voting is a proxy for use of political influence and power. However, the inclusion of this premise weakens the entire argument, which regains consistency (...) only through the adoption of a narrow understanding of what representation is. Introduction.

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.
