 This short treatise has the advantage of contextualizing Bacon’s works in the 1260s in terms of the debates on Latin Averroism. It would appear that Bacon, like Bonaventure and Pecham, was an explicit opponent of the young teachers of the Arts at Paris, especially Siger of Brabant. Bacon and Pecham shared the same scientific concerns (Hackett 2013a). And it would appear that Bacon’s treatises such as the Perspectiva were written with this context in mind. Since, as we have noted above, Bacon provided a philosophical critique of the issues concerning Latin Averroism already as a teacher at Paris in the 1240s, we should see his intervention in the debates of 1266–72 as the criticism of an emeritus Professor of Philosophy, now engaged with the theological arguments of the schools at Paris.
