Alexandre Koyré a réuni trois ans avant sa mort (1964) ces Etudes d'histoire de la pensée philosophique. On retrouve ici la curiosité inlassable de l'auteur des Etudes newtoniennes, qui nous livre une histoire de la pensée philosophique de Zénon à Martin Heidegger, de Spinoza à Condorcet et à Louis de Bonald. L'auteur aborde à la fois les questions sur le vide et l'espace infini au XIVe siècle, celles sur le temps d'après la Logique d'Iéna, dont la doctrine inspirera la (...) phénoménologie de Husserl, de Heidegger et de Sartre, et d'autres sur la langue et la terminologie hégéliennes.

Cet ouvrage d'histoire des idées et de philosophie des sciences rassemble plusieurs études dont le point commun est d'analyser les conséquences majeures de la découverte scientifique de l'infini. Ainsi, Alexandre Koyré montre comment la révolution galiléenne ou la découverte du calcul infinitésimal par Leibniz et Newton ont profondément modifié la conscience qu'a l'homme de lui-même et de sa place dans l'univers.

Historien d'origine russe, Alexandre Koyré (1892-1964) est l'une de ces personnalités exceptionnelles dont les découvertes et les audaces ont profondément marqué l'évolution des idées au XXe siècle. Année par année, de 1922 à 1962, ce recueil nous fait suivre son itinéraire intellectuel à travers les enseignements qu'il donna à l'Ecole pratique des hautes études à Paris et aux Etats-Unis. Il nous permet de mieux comprendre le combat de Koyré pour faire de l'histoire des sciences le coeur même d'une (...) histoire de la pensée humaine, préfigurant aussi bien l'extraordinaire développement de cette discipline depuis un demi-siècle que l'anthropologie historique. Pietro Redondi a largement enrichi le contenu de ce livre à l'occasion de sa réédition, trente ans après sa première parution. Avec une nouvelle présentation, des textes inédits, un index et de nombreuses illustrations, ce volume offre ainsi la meilleure introduction à l'oeuvre de Koyré. (shrink)

"Le Proslogion de Saint Anselme de Cantorbéry - l'œuvre la plus célèbre d'un des premiers et des plus grands philosophes du moyen âge - a joué dans l'histoire de la philosophie médiévale et moderne un rôle de tout premier plan. Il contient, en effet, ce fameux argument, dit..." ontologique ", qui - fortune à nulle autre pareille - sema la division et la discorde parmi les philosophes et les théologien". Alexandre Koyré, Introduction au Proslogion.

In lieu of an abstract, here is a brief excerpt of the content:French Philosophical Thought: Present Trends of French Philosophical Thought *Alexandre Koyré*This is a rather large subject, so you will not be astonished that I shall not treat it in its entirety. French philosophy during the years of war and occupation was pretty active. Though there were some heavy losses: the death of Brunschvicg, posthumous book [...], Héritage de mots, héritage d’idées, 1 a book written when Brunschvicg was (...) in hiding, and a book as “clear and serene as that of Condorcet,” has appeared after the liberation of France; the death of Halbwachs, of Politzer, of Cavaillès, of Lautman shot by the Nazis, of others less well known...; there was the ban on publications by Jewish authors, yet, in spite of this, there has been a surprising number of interesting and even important publications, both during and after the war.It seems that for the elder generation of French philosophers—and that applies not only to philosophers, but to scholars in general—for the generation of men too old to take an active part in the underground move-ment—work, as if nothing happened, has been in the same time a means of escape and a means of resistance. They felt themselves asserting a spiritual tradition that could not be destroyed, and should not be destroyed, and should not be endangered by such contingent “accidents” as Vichy government or even the Gestapo.Thus there have been a new translation of Plato by Robin, books on Plato, on Aristotle, on the medieval (Gilson) and modern philosophy etc., books on philosophy of science, books on sociology, psychology, logic (Méray, Serrus), 2 philosophy of religion, translations of philosophy classics. At the first glance the bibliography of this period (Lavelle, Le Senne, Bachelard, Gilson, etc.) you could have the impression wander in a familiar landscape: yet this would be a completely false impression, because as a matter of fact, this familiar landscape has been completely upturned by the upsurge of existentialism and the revival of Catholic philosophy [End Page 531] (Fessard, 3 De Lubac, Blondel, Nedoncelle, G. Marcel). Under this double impact everything—even the “climate” of philosophy—has changed. Philosophy has become a socially phenomenon.Neither Catholicism nor existentialism are, of course, specifically French intellectual movements. Catholicism is universal ex definitione, and as for existentialism, though French existentialism possesses some specific fea-tures that distinguish it from and even oppose it to the German one, fea-tures that can probably be explained by different national traditions—Descartes, Pascal—it, too, is no more French than it is German. Existen-tialism as such is European by-phenomenon, a definite phase of Western philosophical thought (and European thought, European civilization, at least until the recent—perhaps successful—attempts to destroy it, has been a unity). It originates more than a hundred years ago with Maine de Biran and Kierkegaard, and only has been rediscovered by the twentieth century now. Two thinkers that have been nearly completely neglected by the 19th century—but the 19th century, at least the second part of it, has been a dark age for philosophy—and after the rediscovery or simply the discovery of Kierkegaard in the 20th, it spreads, in Kierkegaard’s wake, from country to country with the usual speed or delay with which ideas travel today. Thus existential philosophy has been, first, developed in Germany in the ‘20s and ‘30s by Heidegger and Jaspers, then—Kierkegaard having been translated into French during the long armistice between the World Wars—in France, some 15 years later. 4 I have heard, by the way, that Kierkegaard has been, or is in the process of being translated into English. So, it is possible that in some 15 or 20 years you will have an existentialism in this country.But to return to France, the rise or upsurge of existentialism has been extraordinarily rapid. It was simultaneous with Husserl’s phenomenolo-gy becoming known in France (Husserl’s last work, Meditations Car-tesiennes, being the text of the lectures he gave in the Sorbonne in 1929, which is now available only in the French translation): from Husserl to...

Die Hauptrichtung der französischen Soziologie ist heute noch die Durkheimsche Schule, die C. Bouglé in seinem Buch „Bilan de la Sociologie française contemporaine“ in den Vordergrund stellt. Diese Schule hat weniger im Sinne einer Einzelwissenschaft gewirkt als durch den Einfluss, den sie auf fast alle sozialen Wissenschaften ausgeübt hat. Deswegen sind die verschiedenen Kapitel des Bougléschen Buches den besonderen Disziplinen : Psychologie, Ethnographie, Geschichte, Jura, Nationalökonomie gewidmet, um die Wechselwirkung zwischen ihnen und der Soziologie, die Verbreitung der soziologischen Methode, des (...) soziologischen Gesichtspunkts zu würdigen. Anschliessend an Bouglé versucht Koyré diese Würdigung zusammenzufassen und kritisch zu beleuchten. Trotz ihrer verschiedenen theoretischen Einstellung kommen diese Disziplinen praktisch zu einer fruchtbaren Zusammenarbeit. Schliesslich macht Koyré zwei wichtige Bemerkungen : 1. über die Tendenz der soziologischen Moral, für welche die soziale Kohärenz der höchste Wert wäre, und 2. über die Wiederentdeckung einer besonderen Schicht der Wirklichkeit durch Dürkheim, nämlich die Kollektivvorstellung, die wie der „objektive Geist“ jedem Individuum innerlich und zugleich äusserlich und für alle verpflichtend ist.The dominant tendency in French sociology is still represented by the school of Durkheim, which receives prominent treatment by C. Bouglé in his book,,, Bilan de la Sociologie française contemporaine“. This school has penetrated nearly all the different social sciences and its influence has not been confined to the boundaries of a separate discipline. The different chapters of Bouglé's book, therefore, deal with psychology, anthropology, history, law, and political economy, in order to analyze the interaction between these separate disciplines and the sociological method.The author attempts to develop further the viewpoint advanced by Bouglé and to throw critical light upon it. He makes his observations along two main lines of thought, namely : first, that the focal conception which represents the supreme value for any sociology and its scientific unity is the conception of social coherence ; and second, that there is a particular area of reality rediscovered by Durkheim, namely the collective idea which, like the „objective mind“, represents for each and every individual a bond internal as well as external.

In so curious, lively, and passionate an epoch as that of Theophrastus Paracelsus, the life and work of few other persons generated as much admiration, as many repercussions and so much influence as did his. At the same time, few others caused as much animosity and hostility. And yet, there are few others about whose work and thought we are less informed. Who was this infamous vagabond? Was he a profound scientist, whose struggles against Aristotelian physics and classical medicine supposedly (...) laid the foundations of modern experimental medicine? Was he a precursor to nineteenth century rational science? Was he an erudite physician, or an ignorant charlatan? A peddler of superstition and quackery, an astrologist, a magician, a gold maker? Was he one of the greatest minds of the Renaissance, or simply a latecomer to Middle Age mysticism, a ‘gothic’? Was he a pantheistic cabalist, an adept of a vague Neo-Platonism and natural magic? Or was he ‘the physician’, ever watchful over suffering humanity; a man who found and formulated a new conception of life, the universe, of God and humanity? Was he, with a deeply Christian mind, one who attempted his own ‘reformation’ in the solitude of the Swiss mountains, who preached an evangelical, sophisticated form of mysticism, without clergy, dogma, and rites? Or was Paracelsus ultimately a Christian who, in spite of his frequently heterodox, even heretical opinions, remained faithful to his Church, preferring Catholicism to the new Protestant churches?

Une apparition miraculeuse dans l'histoire de l'humanite et particulierement dans celle de l'esprit allemand : c'est en ces termes que Schelling, dans sa Philosophie de la Revelation, salue la figure de Jacob Boehme. Si l'on reconnait aujourd'hui a l'oeuvre du celebre cordonnier-philosophe une influence majeure sur le destin de la metaphysique allemande, la pensee du premier philosophe allemand, comme l'appelle Hegel dans son Histoire de la philosophie, demeure encore pour nous deroutante et au premier abord insaisissable. Or, a travers l'etude (...) chronologique des principales oeuvres de Boehme (L'Aurore naissante; Les trois principes de l'essence divine; La triple vie de l'homme; etc.), c'est cette coherence et cette unite souvent tenues pour incertaines que le grand historien Alexandre Koyre parvient a retrouver dans la doctrine de Boehme. Pour le dire d'un mot, c'est la reprise du double probleme de l'existence du mal et de la nature des rapports de Dieu au monde, qui se revele etre le fil conducteur de la theosophie boehmienne. Reprise dont la profonde originalite repose autant sur une formulation inedite de la question que sur les solutions qui en decoulent : loin de reduire le mal a une simple negation, a un neant oppose a l'essence divine, comme le fera Leibniz, heritier de toute une tradition scolastique, Boehme s'efforce au contraire de le penser comme une qualite positive et reelle, montrant que ce n'est que si le mal est positif, donc contingent, que l'on peut esperer un jour sa defaite.
