Jean-Paul Sartre: Mind and Body, Word and Deed celebrates Sartre's polyvalence with an examination of Sartrean philosophy, literature, and politics. In four distinct yet related sections, twelve scholars from three continents examine Sartre's thought, writing and action over his long career. "Sartre and the Body" reappraises Sartre's work in dialogue with other philosophers past and present, including Maine de Biran, Maurice Merleau-Ponty and Didier Anzieu. "Sartre and Time" offers a first-hand account by Michel Contat of Sartre and Beauvoir working (...) together, and a "philosophy in practice" analysis by François Noudelmann. "Ideology and Politics" uses Sartrean notions of commitment and engagement to address modern and contemporary politics, including insights into Castro, De Gaulle, Sarkozy and Obama. Finally, an important but neglected episode of Sartre's life the visit that he and Beauvoir made to Japan in 1966 is narrated with verve and humour by Professor Suzuki Michihiko, who first met Sartre during that visit and remained in touch subsequently. Taken together, these twelve chapters make a strong case for the continued relevance of Sartre today. (shrink)
The physical origin of inertial forces is shown to be a consequence of the local interaction of Dirac's real covariant ether model(1) with accelerated microobjects, considered as real extended particlelike solitons, piloted by surrounding subluminal real wave fields packets.(2) Their explicit form results from the application of local inertial Lorentz transformations to the particles submitted to noninertial velocitydependent accelerations, i.e., constitute a natural extension of Lorentz's interpretation of restricted relativity.(3) Indeed Dirac's real physical covariant ether model implies inertial forces if (...) one considers the real accelerated noninertial motions of general relativity, defined within the absolute local inertial frames associated with the observed local isotropy of the 2.7° K background microwave radiation.(4) Inertia thus appears as a necessary consequence of the real particle motions described by the E.d.B.B. formalism of quantum mechanics.

This bibliographical review of the modelling of the mitotic apparatus covers a period of one hundred and twenty years, from the discovery of the bipolar mitotic spindle up to the present day. Without attempting to be fully comprehensive, it will describe the evolution of the main ideas that have left their mark on a century of experimental and theoretical research. Fol and Bütschli's first writings date back to 1873, at a time when Schleiden and Schwann's cell theory was rapidly gaining (...) ground throughout Germany. Both mitosis and chromosomes were to be discovered within the space of thirty years, along with the two key events in the animal and plant reproductive cycle, namely fecondation and meiosis. The mitotic pole, a term still in use to this day, was employed to describe a morphological fact which was noted as early as 1876, namely that the lines and the dots of the karyokinetic figure, with its spindle and asters, looks remarkably like the lines of force around a bar magnet. This was to lead to models designed to explain the movements of chromosomes which take place when the cell nucleus appears to cease to exist as an organelle during mitosis. The nature of those mechanisms and the origin of the forces behind the chromosomes' ordered movements were central to the debate. Auguste Prenant, in a remarkable bibliographical synthesis published in 1910, summed up the opposing viewpoints of the vitalists, on the one hand, who favoured the theory of contractility or extensility in spindle fibres, and of those who believed in models based on physical phenomena, on the other. The latter subdivided into two groups: some, like Bütschli, Rhumbler or Leduc, referred to diffusion, osmosis and superficial tension, whilst the others, led by Gallardo and Hartog, focussed on the laws of electromagnetism. Lillie, Kuwada and Darlington followed up this line of research. The mid-20th century was a major turning point. Most of the modelling mentioned above was criticized and fell into disuse after disappearing from research publications and textbooks.This marked the onset of a new era, as electron microscopes made possible the materialization and detailed study of the macromolecular elements of the fibres, filaments and microtubules of the cytoskeleton. The successive phases of (a) de Harven and Bernhard's 1956 discovery of the centriole's ultrastructure, (b) its identification with the basal body of the cilia and flagella, confirming the theory set out by Henneguy and von Lenhossek (1898–99), (c) the universal presence of microtubules in animal, vegetal and eukaryotic protist cells, (d) the polymerization-depolymerization induced reversible transformations of the tubulin pool in mitosing cells (Inoue, 1960), (e) ultrastructural comparative studies of the mitotic apparatus of eukaryotes illustrating the Pickett-Heaps integrating concept of the MTOC (microtubule-organizing centre), (f) the possibility ofin vitro experiments on mtocs or on microtubules, brings us upon the present day, which has seen the focus placed on the concept of motor-proteins (kinesin, dynein) and on cell cycle models. The latter are based on a close coincidence between the observable modifications of the mitotic apparatus and the periodic variations in intracellular concentrations of calcium or of certain enzymes (cyclins, Cdc2) during the main transitions of the cell cycle.

The aim of this paper is to present the French approach to Information and Communication, and to sketch out some arguments pro and con for their amalgamation into a unique scientific body. Since its creation in 1975, the French academic field of Information-Communication has proved several advantages in the development of a new scientific corpus, but also some drawbacks. These are going to be reviewed and the question will be posed on the opportunity to generalize that model or to abandon (...) it. The research concludes that a dichotomy between information and communication is certainly not representative of the French field of information and communication; it would rather be a continuum or a multi-polar space. Furthermore it is suspected that Anglo-Saxon separation of information science from communication science is not clear either. International comparison and research program in information – communication are advocated. (shrink)
BackgroundIn the Canadian Alliance for Healthy Hearts and Minds cohort, participants underwent magnetic resonance imaging of the brain, heart, and abdomen, that generated incidental findings. The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants were recruited with (...) a follow-up questionnaire administered to 909 participants at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% of participants, with the highest proportions found in the brain and abdomen. The majority of participants informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

À travers l’ouvrage Le Successeur de pierre par Jean-Michel Truong et à la lumière des théories de Félix Guattari, de Mark B. N. Hansen et de Brian Rotman relatives aux multiples virtualités de l’être humain, cet article étudiera la narration romanesque de l’imbrication des nouvelles technologies de l’information et de la communication dans les processus de matérialisation et d’agentivité du posthumain. Dans son roman, Truong nous invite en effet à repenser la contextualité du corps et de l’identité humaine (...) en substituant un point de vue anthropocentrique et dualiste à une ontologie de l’émergence. This paper investigates Jean-Michel Truong’s book Le Successeur de pierre with Felix Guattari’s, Mark B. N. Hansen’s and Brian Rotman’s theories related to the multiple potentialities of human beings. It focuses more precisely on the fictional narrative of the new information and communication imbrication of technologies into the processes of posthuman’s materialisation and agency. In his novel, Truong indeed invites us to think over the contextuality of the body and the human identity by substituting an anthropocentric and dualistic point of view with an ontology of emergence.

The conceptual history of cognitive science remains for the most part unwritten. In this groundbreaking book, Jean-Pierre Dupuy--one of the principal architects of cognitive science in France--provides an important chapter: the legacy of cybernetics. Contrary to popular belief, Dupuy argues, cybernetics represented not the anthropomorphization of the machine but the mechanization of the human. The founding fathers of cybernetics--some of the greatest minds of the twentieth century, including John von Neumann, Norbert Wiener, Warren McCulloch, and Walter Pitts--intended to (...) construct a materialist and mechanistic science of mental behavior that would make it possible at last to resolve the ancient philosophical problem of mind and matter. The importance of cybernetics to cognitive science, Dupuy argues, lies not in its daring conception of the human mind in terms of the functioning of a machine but in the way the strengths and weaknesses of the cybernetics approach can illuminate controversies that rage today--between cognitivists and connectionists, eliminative materialists and Wittgensteinians, functionalists and anti-reductionists. Dupuy brings to life the intellectual excitement that attended the birth of cognitive science sixty years ago. He separates the promise of cybernetic ideas from the disappointment that followed as cybernetics was rejected and consigned to intellectual oblivion. The mechanization of the mind has reemerged today as an all-encompassing paradigm in the convergence of nanotechnology, biotechnology, information technology, and cognitive science. The tensions, contradictions, paradoxes, and confusions Dupuy discerns in cybernetics offer a cautionary tale for future developments in cognitive science. (shrink)

Do numbers and the other objects of mathematics enjoy a timeless existence independent of human minds, or are they the products of cerebral invention? Do we discover them, as Plato supposed and many others have believed since, or do we construct them? Does mathematics constitute a universal language that in principle would permit human beings to communicate with extraterrestrial civilizations elsewhere in the universe, or is it merely an earthly language that owes its accidental existence to the peculiar evolution of (...) neuronal networks in our brains? Does the physical world actually obey mathematical laws, or does it seem to conform to them simply because physicists have increasingly been able to make mathematical sense of it? Jean-Pierre Changeux, an internationally renowned neurobiologist, and Alain Connes, one of the most eminent living mathematicians, find themselves deeply divided by these questions.The problematic status of mathematical objects leads Changeux and Connes to the organization and function of the brain, the ways in which its embryonic and post-natal development influences the unfolding of mathematical reasoning and other kinds of thinking, and whether human intelligence can be simulated, modeled,--or actually reproduced-- by mechanical means. The two men go on to pose ethical questions, inquiring into the natural foundations of morality and the possibility that it may have a neural basis underlying its social manifestations. This vivid record of profound disagreement and, at the same time, sincere search for mutual understanding, follows in the tradition of Poincaré, Hadamard, and von Neumann in probing the limits of human experience and intellectual possibility. Why order should exist in the world at all, and why it should be comprehensible to human beings, is the question that lies at the heart of these remarkable dialogues. (shrink)
A monster stalks the earth—a sluggish, craven, dumb beast that takes fright at the slightest noise and starts at the sight of its own shadow. This monster is the market. The shadow it fears is cast by a light that comes from the future: the Keynesian crisis of expectations. It is this same light that causes the world’s leaders to tremble before the beast. They tremble, Jean-Pierre Dupuy says, because they have lost faith in the future. What Dupuy (...) calls Economy has degenerated today into a mad spectacle of unrestrained consumption and speculation. But in its positive form—a truly political economy in which politics, not economics, is predominant—Economy creates not only a sense of trust and confidence but also a belief in the open-endedness of the future without which capitalism cannot function. In this devastating and counterintuitive indictment of the hegemonic pretensions of neoclassical economic theory, Dupuy argues that the immutable and eternal decision of God has been replaced with the unpredictable and capricious judgment of the crowd. The future of mankind will therefore depend on whether it can see through the blindness of orthodox economic thinking. (shrink)
Will understanding our brains help us to know our minds? Or is there an unbridgeable distance between the work of neuroscience and the workings of human consciousness? In a remarkable exchange between neuroscientist Jean-Pierre Changeux and philosopher Paul Ricoeur, this book explores the vexed territory between these divergent approaches--and comes to a deeper, more complex perspective on human nature.Ranging across diverse traditions, from phrenology to PET scans and from Spinoza to Charles Taylor, What Makes Us Think? revolves around (...) a central issue: the relation between the facts of science and the prescriptions of ethics. Changeux and Ricoeur ask: Will neuroscientific knowledge influence our moral conduct? Is a naturally based ethics possible? Pursuing these questions, they attack key topics at the intersection of philosophy and neuroscience: What are the relations between brain states and psychological experience? Between language and truth? Memory and culture? Behavior and action? What is a mental representation? How does a sign relate to what it signifies? How might subjective experience be constructed rather than discovered? And can biological or cultural evolution be considered progressive? Throughout, Changeux and Ricoeur provide unprecedented insight into what neuroscience can--and cannot--tell us about the nature of human experience.Changeux and Ricoeur bring an unusual depth of engagement and breadth of knowledge to each other's subject. In doing so, they make two often hostile disciplines speak to one another in surprising and instructive ways--and speak with all the subtlety and passion of conversation at its very best. (shrink)
This is the first English-language introduction to Peter Sloterdijk, the distinguished German philosopher and controversial public intellectual. Sloterdijk, in the tradition of Nietzsche and Heine, is an iconoclast who uses humour and biting critique to challenge many of modernitys sacred thinkers, from Kant to Heidegger, in the process radically reinterpreting the canon of Western philosophy. In this unique textbook, leading Sloterdijk expert Jean-Pierre Couture explains in accessible language Sloterdijks exceptional contribution, breaking his thought down into five key approaches: (...) psychopolitics, anthropotechnics, spherology, controversy, and therapeutics. Sloterdijks frequent public controversies, with supporters of Habermas and the Frankfurt school in particular, are assessed and their significance for current philosophical debates explained. This fascinating book will be an essential companion for those interested in the hybrid aesthetics of thought situated at the crossroads of art and philosophy. Its up-to-date analyses of Sloterdijks recently translated corpus will make it essential reading for all students and scholars of modern European thought. (shrink)
Jean-Pierre Dupuy, prophet of what he calls "enlightened doomsaying," has long warned that modern society is on a path to self-destruction. In this book, he pleads for a subversion of this crisis from within, arguing that it is our lopsided view of religion and reason that has set us on this course. In denial of our sacred origins and hubristically convinced of the powers of human reason, we cease to know our own limits: our disenchanted world leaves us (...) defenseless against a headlong rush into the abyss of global warming, nuclear holocaust, and the other catastrophes that loom on our horizon. Reviving the religious anthropology of Max Weber, Emile Durkheim, and Marcel Mauss and in dialogue with the work of René Girard, Dupuy shows that we must remember the world's sacredness in order to keep human violence in check. A metaphysical and theological detective, he tracks the sacred in the very fields where human reason considers itself most free from everything it judges irrational: science, technology, economics, political and strategic thought. In making such claims, The Mark of the Sacred takes on religion bashers, secularists, and fundamentalists at once. Written by one of the deepest and most versatile thinkers of our time, it militates for a world where reason is no longer an enemy of faith. (shrink)
I will not dwell overlong on the “meaning” of this story. But let me make two essential points. Plato tells us this story as though it were true: it is “a tale which, though passing strange, is yet wholly true.” Those words were to be translated into every language in the world and used to justify the most realistic fantasies. That is quite understandable, for Plato’s story started something new. With a perversity that was to ensure him great success, Plato (...) had laid the foundations for the historical novel, that is to say, the novel set in a particular place and a particular time. We are now quite accustomed to historical novels, and we also know that in every detective story there comes a moment when the detective declares that real life is not much like what happens in detective stories; it is far more complicated. But that was not the case in the fourth century B.C. Plat’s words were taken seriously, not by everyone, but by many, down through the centuries. And it is not too hard to see that some people continue to take them seriously today.As for the “meaning,” following others and together with others, I have tried elsewhere to show that essentially it is quite clear: the Athens and Atlantis of ancient lore represent the two faces of Plato’s own Athens. The former, the old primordial Athens, is what Plato would have liked the city of which he was a citizen to be; the latter is what Athens was in the age of Pericles and Cleon, an imperialistic power whose very existence constituted a threat to other Greek cities.

This volume is about searching for fundamental theory in physics which has become somewhat elusive in recent decades. Like a group of blind men investigating an elephant, one physicist postulates the trunk as a hose, another a leg as a tree, the body a wall or barrier, the tail a rope and the ears as a fan. The organizers of the Vigier series symposia strongly believe cross polination by exploring many avenues of seemingly disparate research is key to breakthrough discovery (...) and solicited papers on all areas of physics deemed pertinent in Astrophysics, Cosmology, nuclear physics, quantum theory, electromagnetism, thermodynamics, vacuum field theory and topology.

L’œuvre de Bentham repose sur quelques paradoxes étonnants. Le premier est que le plaisir est la clé de voûte du système des arts et des sciences et pourtant ce système ne donne lieu à aucune esthétique qui ait l'ampleur de la réflexion de l'auteur sur le droit, la politique, l’éthique, les sciences, les techniques, et même sur la religion. Le second est que l'on a souvent opposé l'utilité à la beauté et bien des auteurs ont vu dans la recherche de (...) l'utilité une enquête incompatible avec la recherche du beau. Mais il n'y a guère de raison à donner pour justifier cette opposition : une chose peut être utile et belle ; une chose belle a au moins l'utilité de sa beauté puisqu'elle produit un plaisir. Le troisième est que l'analyse que Bentham mène à propos du plaisir et de la douleur est assez incertaine ; tantôt le plaisir est tenu pour aussi réel que la douleur, mais, à d'autres moments, la douleur est plus réelle que le plaisir. Le quatrième tient à la difficulté de nier radicalement qu'il y ait des bons goût et des mauvais goûts ; la notion de goût implique cette différence. Enfin, nous avons trouvé si peu de raison qui permette d'exclure les beaux arts du champ de la réflexion utilitariste que nous nous sommes risqués, à partir de quelques éléments donnés par Bentham, à esquisser une esthétique. Il nous paraît toutefois qu'une esthétique utilitariste reste à concevoir. (shrink)
