Paleoneuranatomy is an emerging subfield of paleontological research with great potential for the study of evolution. However, the interpretation of fossilized nervous tissues is a difficult task and presently lacks a rigorous methodology. We critically review here cases of neural tissue preservation reported in Cambrian arthropods, following a set of fundamental paleontological criteria for their recognition. These criteria are based on a variety of taphonomic parameters and account for morphoanatomical complexity. Application of these criteria shows that firm evidence for fossilized (...) nervous tissues is less abundant and detailed than previously reported, and we synthesize here evidence that has stronger support. We argue that the vascular system, and in particular its lacunae, may be central to the understanding of many of the fossilized peri-intestinal features known across Cambrian arthropods. In conclusion, our results suggest the need for caution in the interpretation of evidence for fossilized neural tissue, which will increase the accuracy of evolutionary scenarios. (shrink)

New concepts may prove necessary to profit from the avalanche of sequence data on the genome, transcriptome, proteome and interactome and to relate this information to cell physiology. Here, we focus on the concept of large activity-based structures, or hyperstructures, in which a variety of types of molecules are brought together to perform a function. We review the evidence for the existence of hyperstructures responsible for the initiation of DNA replication, the sequestration of newly replicated origins of replication, cell division (...) and for metabolism. The processes responsible for hyperstructure formation include changes in enzyme affinities due to metabolite-induction, lipid-protein affinities, elevated local concentrations of proteins and their binding sites on DNA and RNA, and transertion. Experimental techniques exist that can be used to study hyperstructures and we review some of the ones less familiar to biologists. Finally, we speculate on how a variety of in silico approaches involving cellular automata and multi-agent systems could be combined to develop new concepts in the form of an Integrated cell (I-cell) which would undergo selection for growth and survival in a world of artificial microbiology.

Jean Starobinski, one of Europe's foremost literary critics, examines the life that led Rousseau, who so passionately sought open, transparent communication with others, to accept and even foster obstacles that permitted him to withdraw into himself. First published in France in 1958, Jean-Jacques Rousseau remains Starobinski's most important achievement and, arguably, the most comprehensive book ever written on Rousseau. The text has been extensively revised for this edition and is published here along with seven essays on Rousseau that (...) appeared between 1962 and 1970. (shrink)

Les douze etudes reunies ici sur Jean Scot Erigene, philosophe irlandais du IXe siecle qui redecouvrit plusieurs intuitions originales du neoplatonisme, constituent les derniers travaux de Jean Trouillard. Apres sa these sur la procession et la purification plotinienne, et a la suite de ses traductions et commentaires de Proclus, il preparait un ouvrage sur Jean Scot qui ne vit jamais le jour. Or, ce que la lecture des esquisses de cette oeuvre laissee en suspens nous apprend, c'est (...) que ce passage a Erigene a ete aussi decisif que celui qui l'avait conduit de Plotin a Proclus. La ou il etait possible de craindre une fixation du mouvement de la pensee neoplatonicienne dans les divisions steriles d'une theologie apologetique, Trouillard nous montre qu'il est au contraire impossible de reduire Jean Scot a la seule problematique categoriale qui ouvre le Periphyseon. Erigene constitue un jalon essentiel dans la latinisation du neoplatonisme ou se manifeste avec une force nouvelle la rigueur systematique d'un courant encore trop ignore, porteur d'un paradigme metaphysique qui n'a pourtant jamais ete aussi necessaire qu'aujourd'hui.

Jean-Paul Sartre is one of the most famous philosophers of the twentieth century. The principal founder of existentialism, a political thinker and famous novelist and dramatist, his work has exerted enormous influence in philosophy, literature, politics and cultural studies. Jean-Paul Sartre: Basic Writings is the first collection of Sartre's key philosophical writings and provides an indispensable resource for readers of his work. Stephen Priest's clear and helpful introductions make the volume an ideal companion to those coming to Sartre's (...) writing for the first time. (shrink)

The philosopher of Mathematics Jean Cavaillès plays an important role in Claude Imbert's thought. His published work had a significant impact after the war. It is largely a reflection on debates on the foundation of mathematics and on two opposed models of axiomatics, foundationalist and constructionist. The philosophy he announced was to be a study of the generativity of conceptual structures, as opposed to a phenomenology of knowledge. He derived from his reflection on invention in mathematics a great scepticism (...) on the ideas of the separateness and unity of consciousness and a criticism of the teleologies inherent in philosophies of consciousness. In that, his work, according to Claude Imbert, made possible the reflections on structures and symbolisms which were to dominate the French context in the following decades. (shrink)

Jean-François Lyotard (1924-1998) was one of the most important French philosophers of the Twentieth Century. His impact has been felt across many disciplines: sociology; cultural studies; art theory and politics. This volume presents a diverse selection of interviews, conversations and debates which relate to the five decades of his working life, both as a political militant, experimental philosopher and teacher. Including hard-to-find interviews and previously untranslated material, this is the first time that interviews with Lyotard have been presented as (...) a collection. Key concepts from Lyotard's thought – the differend, the postmodern, the immaterial – are debated and discussed across different time periods, prompted by specific contexts and provocations. In addition there are debates with other thinkers, including Emmanuel Levinas and Jacques Derrida, which may be less familiar to an Anglophone audience. These debates and interviews help to contextualise Lyotard, highlighting the importance of Marx, Freud, Kant and Wittgenstein, in addition to the Jewish thought which accompanies the questions of silence, justice and presence that pervades Lyotard's thinking.

Buridan was a brilliant logician in an age of brilliant logicians, sensitive to formal and philosophical considerations. There is a need for critical editions and accurate translations of his works, for his philosophical voice speaks directly across the ages to problems of concern to analytic philosophers today. But his idiom is unfamiliar, so editions and trans lations alone will not bridge the gap of centuries. I have tried to make Buridan accessible to philosophers and logicians today by the introduc tory (...) essay, in which I survey Buridan's philosophy of logic. Several problems which Buridan touches on only marginally in the works trans lated herein are developed and discussed, citing other works of Buridan; some topics which he treats at length in the translated works, such as the semantic theory of oblique terms, I have touched on lightly or not at all. Such distortions are inevitable, and I hope that the idiosyncracies of my choice of philosophically relevant topics will not blind the reader to other topics of value Buridan considers. My goal in translating has been to produce an accurate renaering of the Latin. Often Buridan will couch a logical rule in terms of the grammatical form of a sentence, and I have endeavored to keep the translation consistent. Some strained phrases result, such as "A man I know" having a different logic from "I know a man. " This awkwardness cannot always be avoided, and I beg the reader's indulgence. All of the translations here are my own. (shrink)

Jean-Marie Vaysse (1950-2011) hat das philosophische Leben in Frankreich durch die Originalität seines Nachdenkens über die Geschichte der Philosophie dauerhaft geprägt. Spinoza, Heidegger und Deleuze waren seine wichtigsten Weggefährten, mit denen er versucht hat, Fluchtlinien zu entwerfen, um über das Schicksal des zeitgenössischen Denkens nachzusinnen. Seine der deutschen Philosophie von Kant bis Heidegger gewidmete Lehre hat bei seinen Studenten an der Universität Toulouse II - Le Mirail eine sehr lebendige Erinnerung hinterlassen. Dieses Buch ehrt sein Werk, indem es seine (...) außergewöhnliche Art, philosophische Texte zu lesen, und seine Schärfe in der Analyse einiger bevorzugter Lehren hervorhebt und den Geist seiner Methode mit originalen Beiträgen fortführt. Außerdem werden zwei Texte postum veröffentlicht, die den Schwung eines nun abgebrochenen Denkens bezeugen. Jean-Marie Vaysse (1950-2011) a marqué durablement la vie philosophique française, par l’originalité de sa réflexion sur l’histoire de la philosophie. Spinoza, Heidegger et Deleuze ont constitué les principaux compagnons de route avec lesquels il s’est efforcé de dessiner des lignes de fuite pour méditer la destinée de la pensée contemporaine. Son enseignement à l’Université de Toulouse II-Le Mirail, consacré à la philosophie allemande, de Kant à Heidegger, a laissé un souvenir toujours vivant chez ses étudiants. Le présent volume rend hommage à son œuvre, en soulignant la singularité de sa pratique de lecture des textes philosophiques, l’acuité de son analyse de certaines doctrines privilégiées, et en perpétuant l’esprit de sa démarche par des contributions originales. Enfin, nous publions à titre posthume deux inédits, qui témoignent de l’élan d’une pensée interrompue. (shrink)

Jean-Jacques Rousseau est l'auteur de l'entrée "économie politique" dans l'Encyclopédie en 1755. A ce titre, il aurait pu être l'un des fondateurs de cette discipline. Pourtant, la définition qu'il en donne est à l'encontre de la pensée libérale des physiocrates, puis des classiques, et constitue une véritable "anti-économique". En hypertrophiant le rôle de l'Etat et en niant l'intérêt personnel, Rousseau est au contraire l'un des pères du socialsme. En niant la liberté humaine, il nie aussi l'existence de choix éthiques.

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)

La pensée du cinéma ne rencontre d'ordinaire Jean-François Lyotard, dans ses textes sur le cinéma ou non, que par le biais de deux activateurs : l'acinéma et le figurai. Ces deux activateurs, au demeurant, sont fortement représentatifs de la position paradoxale de Lyotard pour les études cinématographiques : si l'acinéma a été le plus souvent critiqué pour sa radicalité voire son sectarisme, n'ayant de fait guère de postérité, il en va tout autrement du figurai, lequel a trouvé dans les (...) films un terrain fertile d'investigation. Tout autant représentative est la méconnaissance en théorie du cinéma de nombreux autres textes de Lyotard portant sur le cinéma ou sur des films, et dont on ne parle jamais, ainsi que de sa philosophie postérieure à sa période libidinale, qui ne semble pas avoir encore trouvé d'échos particuliers en régime filmique. Le présent ouvrage fait précisément le pari de ces deux directions. A partir d'un autre Lyotard, ou du même mais envisagé très différemment, se dessinera progressivement une possibilité de penser le cinéma qui ne devra plus rien au figurai, à l'abstrait ou à l'expérimental, dont Lyotard le premier a fini par revenir, mais qui, singulièrement, ouvrira à une originale théorie du cinéma figuratif. " Méfiance envers les figuratifs quand ils ont de l'âme ", peut-on lire dans Que peindre?... (shrink)

Tous les textes publiés dans l'ouvrage parlent directement de l'œuvre de Jean-Michel Berthelot. La première partie, " Sociologie de Jean-Michel Berthelot ", rassemble les contributions restituant des traits de son œuvre à l'aide d'études de cas précis ou de panoramas plus larges, et balise des domaines de recherche dans lesquels il s'est illustré : sociologie de l'éducation, du corps, des sciences, épistémologie des sciences sociales. La deuxième partie rend compte des perspectives ouvertes par ses travaux et de la (...) manière dont des chercheurs ont mis en œuvre ses réflexions pour leurs propres recherches. Il s'agit donc de restituer la façon dont on peut faire de la sociologie " avec " Jean-Michel Berthelot - à l'aide de ses travaux et des jalons qu'ils posent. La troisième partie est biographique en restituant l'itinéraire académique, intellectuel et humain de Berthelot, que ce soit son parcours universitaire et social, notamment à l'ENS durant mai 68, ou encore sa période " toulousaine " où sa carrière universitaire a débuté et qui en constitue une partie essentielle. Dirigé par Jean-Christophe Marcel et Olivier Martin, cet ouvrage rassemble les contributions de collaborateurs, d'anciens étudiants ou de proches collègues de Jean-Michel Berthelot. (shrink)

On the subject of football, Serge Mésonès, former French international turned journalist, wrote that ?the true miracle remains the birth of a great team; everything which could contribute to this deserves consideration. Whatever happens, the coach and his group will always form that tandem which Bella Guttman used to compare to a symphony orchestra and their conductor: there is a significant difference between the performance when Toscanini is conducting, and that when the conductor is mediocre? (Mésonès 1992, 12). With the (...) aim of better understanding the issues of such an assertion, in this article we will develop the theoretical elements that we began to tackle in the book Teaching Collective Sport in Schools (1999).1 This will involve clarifying, and going into detail on, some conceptions relating to the long journey that is the formation of a sporting group, exploring one scenario at a time.

Est-il possible de parler de ce qui n’est pas ou d’y penser sans présupposer une forme d’être pour cela même que nous pensons ne pas exister? La vieille énigme parménidienne, qui hante toujours la philosophie contemporaine, est au cœur non seulement de la philosophie médiévale mais aussi des études médiévales, comme en témoigne le récent ouvrage d’Alain de Libera sur la référence vide. L’objet de cette étude est en comparaison beaucoup plus...
