Faith and Rhetoric in Giles of Rome

Giles of Rome's view of faith in the reportatio of his questions on book III of the Sentences (q. 38, d. 23) is founded on a likening of faith to rhetoric. The firm intellectual assent that characterizes them both is caused by the will, motivated by emotion, or affective bias. This paper argues that this is made possible by Giles' move away from Aquinas' position on the assent produced by rhetorical discourse, which Aquinas thought to be of little certainty, while Giles affirms that, based on the will's natural control over the intellect, it can be as certain as faithful assent, and that the psychological process that produces it can serve as a model for that which produces faithful assent. The new function Giles gives to rhetoric underlines the evolution of thirteenth-century views on faith, as shown through a comparison of Giles' view with two other doctrines of faith that use examples similar to the one Giles employs: those of Philip the Chancellor and Peter John Olivi. For the former, faith founded on affective bias is a typical example of non-virtuous faith, while for the latter, just as for Giles, it is the very model of virtuous faith.
