Commentary on Wilkins’s Essay
By Jonathan McIntosh,

In “Henry of Ghent and the Waning of the Divine Light,” Shane Wilkins presents Ghent’s epistemology as an alternative to St. Thomas’s thirteenth-century synthesis of Aristotelian naturalism and Augustinian supernaturalism. Being more familiar with Aquinas’ ideas than I am with Ghent’s, I would like to spend this commentary developing briefly a point that Wilkins makes in regard to Aquinas, in the hope that it will encourage further discussion of the similarities and differences between these two great thinkers.
Wilkins notes that, his Aristotelianism notwithstanding, Aquinas still “tried to make a little room for illumination by identifying God’s gift of divine light with his bestowing the soul with the agent intellect.” To this end Wilkins cites a passage from Aquinas’s Disputed Questions on Truth in which the latter likens the agency of the agent intellect (whereby the intelligible form of a sensible object is abstracted from the imagination) to that of a “light.” As Thomas presents it here, this light, far from it being an unmediated, supernatural gift occasioned by the cooperative work of the senses and imagination, is instead said to be imparted to the agent intellect “at the start,” for in this light is “mediated” the universal concepts by which we have “a prior cognition” of those things experienced through the senses. In the passage cited, Thomas concludes with what appears to be an allusion to Plato’s famous argument in the Meno dialogue that in the act of knowing we are really “recollecting” what we already knew: “In this connection there is truth in the view that the things we learn, we already had knowledge of.” In his commentary on Thomas’s passage, finally, Wilkins makes the point that if this “constitutes Thomas endorsing illuminationism, it is clear that the theory is present in a sense very much restricted from the one which Augustine gave it.” The chief difference Wilkins notes is that, whereas illumination for Augustine and early Franciscans was “an ongoing occurrence,” Thomas seems to limit the role of illumination to “‘the start’ of life.”
In what is perhaps Thomas’s most extended treatment of the themes of divine illumination, however, his Exposition of Boethius’s De Trinitate (EBT), I suggest we see a different picture emerging. For as Thomas expressly argues there, God is always the cause of the soul’s natural light, “not only of its coming into existence but of its existence itself. In this way, therefore, God is constantly at work in the mind, endowing it with its natural light and giving it direction. So the mind, as it goes about its work, does not lack the activity of the first cause” (EBT 1, 1, ad 6, Armand Maurer translation). On this understanding, knowledge would seem to be never truly divisible into purely natural and supernatural phases, but is always simultaneously a natural and supernatural event. As John Milbank has argued, in Thomas the “Augustinian and Neoplatonic construal of truth as inner illuminatio” is not so much pitted against Aristotelian naturalism as it has in fact undergone an “Aristotelian detour” and transformation “through the truth embodied in finite creatures and conveyed to us only via the senses” (Truth in Aquinas 23). If so, the question is raised as to whether Thomas might not in fact achieve an even greater integration of divine and natural “light” than Ghent (at least as Wilkins has represented him), inasmuch as the latter still views the knowing act as indeed in principle divisible into, on the one hand, a “thoroughly naturalistic” (as Wilkins has it) phase that is able to semi-autonomously grasp the “truth of a thing,” and on the other hand, a later, merely corroborative, supernatural phase that knows “the thing’s truth” in light of the divine exemplar. If so, is it any wonder that Ghent’s oil-and-water approach to uniting the mind’s natural powers of reason and God’s own power of illumination should have excited Scotus’s ire, and thus arguably helped produce an even more thorough-going Aristotelian naturalism floating within an even more extremely conceived theological voluntarism? Let the comments commence.
