 Avicenna’s theory of the permanence of substantial forms was often mentioned, but rarely accepted in the Latin West. Averroes’ position, that the elementary forms can be diminished and augmented, found many supporters, among them Henry of Ghent, Petrus Johannes Olivi, Richard of Middleton, John of Jandun and several members of the Merton school of the fourteenth century (Maier 1952, 36–46). Many authors accept Averroes’ position with modifications, especially by reinterpreting the thesis of the intension and remission of elementary forms. Henry Bate and Dietrich of Freiberg argue that the diminished forms assume the character of potential forms and thus join the matter of the compound; the form of the compound is a form added to these diminished forms. For Averroes, in contrast, the combination of the diminished forms was identical with the new form of the compound. In the Renaissance, the issue continued to be discussed. There was disagreement even among the followers of Averroes. Some, as Marcantonio Zimara, held that the form of the compound was added to the other forms, others, as Jacopo Zabarella, argued against such addition (Maier 1952, 46–69).
