First recorded in the 14th century, the analogy of spit-roast meat argues that expecting the Sun to rotate around a strictly immobile Earth would be just as ludicrous as trying to move the fire around the roasting meat. On the contrary, it should be the Earth that spins upon itself in order to glean, from all possible angles, all the benefits of the Sun, just as it is the meat’s responsibility to turn on the spit before the motionless fire for (...) it to be perfectly cooked on all sides. Aimed at demonstrating, in geocentricism, the plausibility of the rotation of the Earth and, in heliocentrism, at supporting the physical reality of this terrestrial rotation, nowadays this analogy barely elicits more than an amused, or even condescending, smile. However, its continued long-term existence and its frequency of use — from the 14th to the 19th century, we found it mentioned by no less than 45 different authors — incited us to finally pay attention to it. We then noticed that beyond its explicitly cosmological scope, it raises, in its own way, the question of the purpose of the natural world: had the latter been conceived based upon humankind, then it is normal, despite what this analogy advocates, that the Sun is at the service of something more important than itself by rotating, to the profit of humankind, around the Earth; conversely, since such an infringement of the rule of common sense, as illustrated by this analogy, can neither be justified nor tolerated, it is up to the Earth to move around the Sun. Tracing the vicissitudes of this analogy, over 6 centuries, is thus not only about reconstructing the largely forgotten history of a presently obsolete analogy, but also about discovering the deeper meaning, henceforth incomprehensible, behind it. In describing how this meaning became progressively lost, one can finally pro­vide an understanding of why, in the present day, we are no longer capable of more than an amused smile when happening upon it!

Etudie les aspects, les moyens et les précédents de l'interprétation que fait Plotin (205-270) de l'idée platonicienne de participation. L'auteur met en avant l'importance de la notion d'imitation dans l'hypothèse d'un processus d'engendrement des existences à partir des trois réalités véritables (l'Un, l'Intellect et l'Ame).

In what is quite possibly the most famous passage of the De revolutionibus, Copernicus implies that nobody could ever place this supreme flaming torch that is the Sun in another or better place than that from which it can illuminate everything simultaneously, namely the centre of this extremely beautiful temple that is our world. Considering the fact that he leaves an interrogatory twist to this argument of convenience, and since he makes this statement without any justification as it seems entirely (...) evident to him, certain Copernicans choose to illustrate this by means of an analogy: if indeed the Sun must be positioned thus, it is because the most appropriate place for the torch intended to illuminate the room is at its centre, and not in one of its corners. Despite the heliosophy of the Renaissance having been shared by both geocentrists and Copernicans alike, this "torch" argument does not appear to have achieved much success: rarely adopted by the Copernican camp, it was even contested by some of them; as for the geocentrists, it held no appeal for them whatsoever. Did this argument of convenience therefore not benefit from the self-evidence attributed to it by Copernicus, and from, in his wake, it's continued support by a good many commentators? As is often the case when it comes to the history of thought, the pseudo-obviousness of this argument is merely the fruit of a blatant anachronism: presenting heliocentrism as the cosmological system that finally grants the Sun its worthy centrality by placing it in the centre of the room and not in a corner, is to ignore the fact that this star of the day already enjoyed, in geocentrism, a centrality esteemed to be perfectly in keeping with both its dignity and its inherent illuminative function. Having lost their grasp on this worldview that no longer belonged to them, the Copernicans thus put forward an argument which, for the geocentrists, is worthless. Yet they could have argued the objective superiority of their centrality over that accorded to the Sun by geocentrism: while the latter is only numerical, on a purely planetary scale, and frankly fictitious, the former is thoroughly spatial, of cosmic proportions and, at least on first approximation, very real. In order to produce arguments of convenience that could carry their own weight, the protagonists of the new cosmology would have benefited from getting to know the world vision of their adversaries a little better instead of addressing them from their own point of view; similarly, instead of treating as an obvious fact that which is only evident to one of the two parties present, historians of scientific thought would also be well advised to have a better understanding of the world vision of those who history now considers as the losers!

The aim of this study is to challenge the current scholarly consensus depicting Plato as having renounced the political ideal of his Republic, and modified it in favour of a in his last work, the Laws. The study shows that Plato's critique of democracy remains as firm in the Laws as it was in the Republic and the Statesman, refusing to concede any room to any form of popular sovereignty that could threaten the government of knowledge.

Alors qu’il était précepteur en Suisse, le jeune Hegel traduisit minutieusement un libelle révolutionnaire dénonçant l’oppression que les autorités bernoises exerçaient sur le Pays de Vaud. Il publia ces Lettres de Jean-Jacques Cart à son retour en Allemagne, en 1798, sous le couvert d’un anonymat qu’il ne leva jamais. Derrière le caractère anecdotique de cette première publication, on peut déceler des enjeux qui conduisirent à l’instauration de l’idéalisme spéculatif. Le motif de la lutte pour la reconnaissance, en particulier, semble (...) y trouver sa première apparition. Plus fondamentalement cette première publication éclaire le travail d’élaboration stylistique conduisant progressivement au système, avec, à l’horizon, la question de la portée pratique de la philosophie.

During the Second Industrial revolution, consulting professor bridged higher education institutions with industry and government. A concept like the utilitarian research regime by Terry Shinn can explain their material and intellectual production by allowing for a reconstruction of their social networks. Pierre‐Paul LeCointe and Louis Bourgoin , associates in an engineering consultancy office, institutionalised a consultation service at the Laboratory of Industrial Chemistry of the École Polytechnique of Montreal . The two industrial chemists were thereby able to obtain financial, material (...) and human resources through exchanges with industrialists, business men and civil servants; consequently, their material and intellectual production is marked by the preoccupations of the industries and government with whom they exchanged. Industrial development in Canada was, in part, based on the work of these consultants who helped private companies analyse primary resources, standardize fabrication procedures and adapt the production to regulations. The government also offered technological assistance to businesses thanks to consultants, while regulating the markets and producing industrial standards. The inception of a utilitarian research regime results from the conjunction of these different factors. Finally, on Bourgoin's initiative, the École Polytechnique created a research centre based on the model of consulting laboratories. (shrink)

resumo Esse artigo busca mostrar, em contraste com uma tradição já estabelecida, que a filosofia clássica alemã, longe de fazer do indivíduo simples apêndice do Estado, propõe uma verdadeira teoria do Estado de direito , e isso, antes mesmo que esta tenha sido formulada pelos juristas liberais. Mas se trata de uma teoria crítica, que põe em evidência o caráter ilusório da idéia liberal segundo a qual a sociedade civil poderia furtarse inteiramente à tutela do Estado. Para Fichte e para (...) Hegel, mas também para Kant, apenas um Estado verdadeiro, com os atributos de sua potência, pode ser um verdadeiro Estado de Direito. palavras-chave Fichte; Kant; Hegel; sociedade civil; liberalismo; Estado de direito.

The aim of this study is to challenge the current scholarly consensus depicting Plato as having renounced the political ideal of his Republic, and modified it in favour of a 'mixed constitution' in his last work, the Laws. The study shows that Plato's critique of democracy remains as firm in the Laws as it was in the Republic and the Statesman, refusing to concede any room to any form of popular sovereignty that could threaten the government of knowledge.

resumo O presente artigo investiga as relações entre individualidade e espírito objetivo no quadro da filosofia política hegeliana. Retomando o significado mediador contido na idéia de “vida ética”, procura-se apontar uma alternativa à interpretação de que Hegel seria partidário de um institucionalismo forte, que dissolveria o indivíduo quando de sua institucionalização sócio-política. palavras-chave vida ética – subjetividade – indivíduo – instituição – linguagem universal.

Combinant des méthodes employées en ethnoscience et en sociolinguistique, cet article formule une hypothèse destinée à expliquer pourquoi, dans certains types de situations, les membres de la société apache occidentale s’abstiennent de parler. En dépit de l’extrême insuffisance des données interculturelles sur le silence, certaines preuves recueillies suggèrent que cette hypothèse peut également s’appliquer à d’autres sociétés.

Les sources augustiniennes du cogito cartésien – voilà assurément une question qui n’aura jamais sérieusement préoccupé Martin Heidegger! Nous voudrions cependant suggérer, dans notre étude, que les différentes lectures critiques que Heidegger entreprend de la métaphysique cartésienne, dès les années du premier enseignement de Fribourg, à travers le premier cours donné à Marburg notamment, et jusqu’à Sein und Zeit, sont singulièrement aimantées par une question augustinienne : la question que je suis devenu pour moi-même précisément, et que c’est d’abord à (...) partir de cette question et de la problématisation du mode d’être du sum et de l’ego qu’elle commande, que Heidegger déploie son débat ou son différend avec l’instauration cartésienne d’une métaphysique de la subjectivité.Les méditations cartésiennes de Martin HeideggerAuf den ersten Blick könnte man den Eindruck gewinnen, Heidegger habe den augustinischen Wurzeln des cartesianischen « cogito » nie ernsthafte Beachtung geschenkt. Diese weithin verbreitete Auffassung versucht der folgende Artikel durch eine eingehende Analyse bestimmter Kerntexte aus Heideggers früher Schaffensperiode zu revidieren, die von einer kritischen Auseinandersetzung mit der cartesianischen Metaphysik geprägt sind. Bei genauerer Betrachtung wird deutlich, da dieser wiederholte Rückgang auf Descartes – angefangen von den Jahren der ersten Freiburger Lehrtätigkeit über die Marburger Vorlesung Einführung in die phänomenologische Forschung bis hin zu Sein und Zeit – von einer eminent augustinischen Fragestellung motiviert ist, nämlich der Frage, zu der ich mir selbst geworden bin. Vor diesem Hintergrund erschliet sich erst die Art und Weise, in der Heidegger der Frage nach der Seinsart des « sum » und des « ego » nachgeht, um von diesem Ansatz her die cartesianische Begründung einer Metaphysik der Subjektivität einer eingehenden Kritik zu unterziehen.

Durante la vida de Newton, su Óptica se publicó en sucesivas ediciones. En esta medida, fijar una versión definitiva del texto es problemático, por lo cual se hace necesario recurrir no sólo al texto sino también a los contextos y a la intertextualidad. El artículo plantea las dificultades de las lecturas tradicionales de la Óptica (como respuesta a teorías de la visión y la luz precedentes y como parte de la físico-teología inglesa) y argumenta a favor de una lectura teológica (...) del tratado, desde la epistemología de la Óptica y del entusiasmo religioso que Newton rechazó categóricamente. Consecuencia de esta lectura es una reformulación del texto, el contexto y la intertextualidad que hacen comprensible la Óptica de Newton. (shrink)

Quel sens revêt aujourd’hui l’appel à mener un mode de vie philosophique, quand les philosophies ne se conçoivent plus comme devant être vécues, quand les penseurs même qui soulignent l’importance de la pratique ne semblent plus voir dans la philosophie un possible art de vivre? En réalité, l’invite à vivre philosophiquement, reprise par Pierre Hadot aux Anciens, découle de la reconnaissance du primat de la pratique, et de la considération sérieuse de ce que signifie philosopher : une vie accomplie aspire (...) à la cohérence intérieure, elle est à la fois critique et ouverte, elle veut se grandir, dans ses actes et ses œuvres. La vérité nous échapperait-elle, que nous gagnerions toutefois la possibilité, par et dans l’activité philosophique, de forger par nous-mêmes notre vie, d’y trouver notre vérité. (shrink)
