 Furthermore, many scholars argue that the Aristotelian doctrine of the formal identity of knower and known plays a significant role for Aquinas in particular. If (on this interpretation) the knower quite literally takes on the form of the known object, and thus becomes identical to the known object in this formal way, then there is no chance for error. The knower is not at a remove from the known object at all, on this account. There is considerable disagreement about Aquinas’s motivations here; for a few representative views, see Gilson (1986), MacDonald (1993), Pasnau (1997), Jenkins (1997), and Hibbs (1999).
