Download E-books La naissance de la science, tome 2 : Grèce présocratique PDF

By André Pichot

Les sciences de los angeles Mésopotamie, de l'Égypte et de l. a. Grèce présocratique forment un ensemble cohérent, où les connaissances mésopotamiennes et égyptiennes (acquises sans véritable méthode) ont été reprises dans un esprit tout différent par l. a. Grèce. À los angeles Mésopotamie dont les plus grandes réussites scientifiques sont liées aux mystiques mumérique et astrologique, à l'Égypte plus soucieuse d'esprit pratique, succède une technological know-how grecque qui se préoccupe moins d'accumuler les résultats 'positifs' que de trouver des principes généraux et une explication rationnelle (ou tendant vers los angeles rationalité). Cet ensemble cohérent forme los angeles resource principale de l. a. technological know-how occidentale. Celle-ci ne négligera pas d'autres apports (indiens, chinois, arabes...), mais ils se grefferont sur un corpus dont les grands principes et l'orientation générale auront déjà été établis.

La technological know-how, en ses origines, a suivi deux voies distinctes : l. a. voie des objets et los angeles voie de l'esprit scientifique.
La voie des objets consiste en los angeles première différenciation d'études qui se structurent autour d'objets propres (les nombres, les astres, les êtres vivants...), mêlant empirisme, rationalité, magie et mystique.
La voie de l'esprit scientifique est d'abord celle, philosophique, par laquelle l. a. rationalité est élevée au rang de critère de vérité. C'est ensuite l. a. voie par laquelle les disciplines préscientifiques sont reprises et transformées dans cet esprit nouveau, propre à l. a. démocratie grecque.
