Ame intellective, âme cogitative: Jean de Jandun et la duplex forma propria de l'homme

The article analyses the idea that according to the averroist Jean de Jandun, Master of Arts in Paris at the beginning of the 14th century, human beings are composed of a «double form» the separated intellect on the one hand, the cogitative soul on the other hand. After recalling several major accounts of the time, we explore Jean's reading of Averroes' major conceptions concerning the problem. Finally, we challenge the idea according to which we observe in his writings the radical thesis of a sometimes cogitating sometimes thinking «double human being» that makes of the homo intelligens a punctual and exclusive new being, which is accidentally produced while the thinking takes place.
