Prologue A[1] A[2] A[3]
Next in order, the question arises as to the medium of the angelic knowledge. Under this heading there are three points of inquiry:
A[1] Do the angels know everything by their substance, or by some species?
A[2] If by species, is it by connatural species, or is it by such as they have derived from things?
A[3] Do the higher angels know by more universal species than the lower angels?
