Abstract

Peter John Olivi is oft characterized as having a particularly radical view, concerning the activity of the soul in cognition/appetite, where the soul’s cognitive and appetitive powers are the proper efficient causes from which even their most basic acts are produced; in contrast, external corporeal objects are insufficient to produce any direct effect on these “higher” powers. Olivi’s view can appear to be untenable, either leaving external objects completely outside of psychological explanation or requiring some novel type of cause outside of the typical medieval-Aristotelian causal framework. However, in this paper, I seek to alleviate this concern by considering Olivi’s response that the object can still be considered a “broadly efficient cause”; in particular, I look at how Olivi’s same view is endorsed by Gonsalvus of Spain, one of Olivi’s students. I argue that Gonsalvus takes a more diplomatic approach, despite endorsing essentially the same view, which shows that their shared active view of cognition/appetite can safely fit into a wider medieval-Aristotelian causal framework with some further explanation. As I explain, this interpretation of Olivi, alongside Gonsalvus, helps put later active views of cognition/appetite (e.g., from John Duns Scotus), and their own qualifications, into a more complete context.
