Question 55 — The Medium of the Angelic Knowledge

Next in order, the question arises as to the medium of the angelic knowledge. Under this heading there are three points of inquiry:

(1) Do the angels know everything by their substance, or by some species?

• (2) If by species, is it by connatural species, or is it by such as they have derived from things?
• (3) Do the higher angels know by more universal species than the lower angels?
