In page Petrus Ramus:

"

Ramus, as graduate of the university, started courses of lectures. At this period he was engaged in numerous separate controversies. One opponent in 1543 was the Benedictine Joachim Périon.[1] He was accused, by Jacques Charpentier, professor of medicine, of undermining the foundations of philosophy and religion. Arnaud d'Ossat, a pupil and friend of Ramus, defended him against Charpentier.[2] Ramus was made to debate Goveanus (Antonio de Gouveia), over two days.[3] The matter was brought before the parlement of Paris, and finally before Francis I. By him it was referred to a commission of five, who found Ramus guilty of having "acted rashly, arrogantly and impudently," and interdicted his lectures (1544).
