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)

Jean-Pierre Vernant delineates a compelling new vision of ancient Greece that takesus far from the calm and familiar images of Polykleitos and the Parthenon, and reveals a culture ofslavery, of blood sacrifice, of perpetual and ritualized warfare, of ceremonial hunting andecstasies.In his provocative discussions of various institutions and practices including war,marriage, and the city state, Vernant unveils a complex and previously unexplored intersection ofthe religious, social, and political structures of ancient Greece. He concludes with a genealogy ofthe study (...) of myth from antiquity to the present, and offers a critique of structuralism.Jean-PierreVernant is Professor Emeritus of Comparative Study of Ancient Religions at the College de France inParis.

Jean Pierre-Vernant and Pierre Vidal-Naquet are leaders in a contemporary French classical scholarship that has produced a a stunning reconfiguration of Greek thought and literature. In this work, published here as a single volume, the authors present a disturbing and decidedly non-classical reading of Greek tragedy that insists on its radical discontinuity with our own outlook and with our social, aesthetic, and psychological categories. Originally published in French in two volumes, this new single-volume edition includes revised essays (...) from volume one and is the first English translation of both volumes.Pierre Vidal-Naquet is Director of Studies and Professor of Sociology at the Ecole Pratique des Hautes Etudes in Paris.

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.

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.
