besides his "logica", he wrote "consequentiae", a treatise on the syllogism, and "obligationes" or "scholastica militia", a series of "formal exercises in scholastic dialectics." he had some not unfriendly controversy with his colleague john wyclif, against whom he defended the possession of wealth by the clergy, and held that in the church abuses were better than disturbance. he also attacked wyclif's doctrine of predestination. his positions are gathered from wyclif's "responsiones ad rodolphum strodum" (ms. 3926, vienna imperial library).
