Saint Bonaventura (1221-1274), who, as General of the Franciscan order, forbade Bacon to publish, was a man of a totally different kind. He belonged to the tradition of Saint Anselm, whose ontological argument he upheld. He saw in the new Aristotelianism a fundamental opposition to Christianity. He believed in Platonic ideas, which, however, only God knows perfectly. In his writings Augustine is quoted constantly, but one finds no quotations from Arabs, and few from pagan antiquity.
