Petrus Ramus, as a graduate of the Collège de Navarre, one of the colleges of the University of Paris, has opened courses of lectures; but his audacities have drawn upon him the hostility of the conservative party in philosophy and theology.

The influential anti-Aristotelian logician is engaged in numerous separate controversies during this period.

One opponent in 1543 is the Benedictine Joachim Périon, a prolific translator of Aristotle’s works.

Continuing his attack on Aristotle and his modern disciples, Ramus creates a new two-part logic to replace Aristotle's Organon in his Dialecticae partitiones ("Structures of Dialectic”), published in 1543.

He is accused by Jacques Charpentier, professor of medicine, of undermining the foundations of philosophy and religion.

Arnaud d'Ossat, a pupil and friend of Ramus, defends him against Charpentier.

Ramus is made to debate Goveanus (Antonio de Gouvea), over two days.
