His own view is that many truths knowable per se by the wayfarer can be known, not only a posteriori but also a priori, "under the aspect of deity by a form of cognition that is superior and more noble than any knowledge by faith". He proves one part of this by saying that an intellect able to understand a subject under the aspect of a subject [ie the subject of a science] can understand a principle virtually included in the subject, and further conclusions contained in a principle, because as the term of the subject is the cause of the principle so is the principle the cause of a conclusion. The object of the science of theolgy Scotus thinks can be known by means of abstractive cognition (as distinguished against intuitive).
The second part of his position, that the cognition the wayfarer has of God under the aspect of deity is more perfect and more certain than all cognition of faith, Scotus supports with the claim that whatever God can do by means of a second cause, he can do per se efficiently without it. But God by the mediation of some object can cause certain knowledge and certain assent so that the will is not able to dissent. Therefore God can do this per se without a medium (Scotus is thinking of the prophets here, who couldn't dissent from what was revealed to them. apparently).
Now comes the interesting part, and our quote for the evening:
"From this I infer two conclusions. The first is that in the cognition of God there are five grades. The first is to know truths intuitively, truths which are knowable about God and knowable distinctly by the notion of the subject known intuitively and distinctly, and that grade is not commonly possible to the wayfarer. The second grade is to know something certitudinally in something representatively distinctly known, and that grade is possible for a wayfarer. The third grade is to know something with certitude so that its certitude is not subject ot an actof the will, and that grade was in the prophets. The fourth grade is to know explicitly those things which are contained in the Scriptures by which brings pious aid and defends agains the impious by knowing how the solve the doubts of others and to fortify them with good arguments, and that grade is of the great ones in the church ['maiorum':Wolter translates this as elders]. The fifth grade is to know those things which are necessary for salvation, which is of the simple ones, because they are not able to search through all things contained in scripture."
The second conclusion he derives is that the light Henry talks about is not something that comes with extended study, but is there by a supernatural infusion who possesses it as a free gift to the intellect. Which is about as much as I've seen Scotus ever grant to the notion of divine illumination.
