 As the newly rediscovered Aristotelian texts began to find their way into university curricula in the thirteenth century, more conservative faculty reacted. Bonaventure and Henry were among the latter, and each argued against those who sought to replace the reigning Augustinianism with too many new Aristotelian elements. Aquinas, Siger of Brabant, and others sought to synthesize Aristotle and Christianity in a much more thoroughgoing way than Henry thought acceptable. And as part of the commission organized at the Pope’s request, Henry helped create a list of 219 propositions—some held by Aquinas himself—that were condemned as heretical to the Catholic faith in 1277 by Bishop Etienne Tempier.
