Sic igitur uirtutes formarum substantialium simplicium corporum in corporibus mixtis saluantur." 30 Cf. Maier's (1952, 105–108) report on Scotus's views. R. Wood, although she notes that Scotus went as far as to reject Aristotle, follows Maier's assessment of Scotus as developing the Thomist position: "By the fourteenth century, not Averroes but Aquinas had more followers on the subject of mixture, and those followers included not only Dominicans, but Franciscans, 326 Lucian Petrescu I will follow Sctous's discussion on II Sent., d. 15 from the Reportata parisiensia (Reportatio 2A, printed in John Duns Scotus 1968, vol.
