Cartesio e il grande progetto della ragione Fra pensiero e passione: vita e opere di un genio René Descartes ( in latino Cartesius, in italiano Cartesio ) nasce il 31 marzo a La Haye in Turenna, terzo figlio di Joachim Descartes, avvocato e consigliere al Parlamento di Bretagna a Rennes e di Jeanne Brochard. La famiglia, che possiede rendite e terre, conta numerosi magistrati, medici e funzionari delle imposte: il padre è insignito del titolo di "escuyer", primo grado della nobiltà. Alla morte della madre per parto, René è affidato alla nonna materna. Di salute delicata, impara a leggere ed a scrivere in casa, sotto la guida di un precettore. Compie gli studi nel collegio gesuita di La Fléche, dove resterà circa nove anni seguendo i tre corsi regolari di grammatica, retorica e filosofia che comprendevano insegnamenti di logica, dottrine umanistiche, fisica, metafisica e matamatica con elementi di teoria musicale.A causa delle sue condizioni di salute, gode di un regime di favore, con una camera personale e la possibilità di riposare a letto sino alle dieci di mattina, esentato dall'obbligo di sveglia alle cinque. Uscito dal collegio, ubbidendo ai desideri del padre, si reca a Poitiers per studiare diritto.

Roberval, Gilles Personne de 1. Dates Born: near Senlis, 10 August 1602 Died: Paris, 27 October 1675 Dateinfo: Dates Certain Lifespan: 2. Father Occupation: Peasant/Small Farmer He came from a family of simple farmers. Although nothing explicit is said, the phrase "simple farmers" says to me that they were poor. What he himself said about his education certainly says the same thing. 3. Nationality Birth: French Career: French Death: French 4. Education Schooling: No University Roberval writes that he was born and educated among the people (inter multos). He left his family at an unknown age. He embraced the study of mathematics at the age of fourteen. He travelled to various regions of the country earning a living from private lessons. He continued to educate himself by attending classes at the universities in the regions he visited. In Bordeaux where he met Fermat and took on François du Verdus as a pupil he may have attended the university. 5. Religion Affiliation: Catholic He is buried in the church of St. Severin. Auger writes that according to Lebeuf Roberval is buried in the choir, but Auger was unable to locate any signs. 6. Scientific Disciplines
