Prologue A[1] A[2] A[3]
We must now consider how the human soul knows what is above itself, viz. immaterial substances. Under this head there are three points of inquiry:
A[1] Whether the human soul in the present state of life can understand the immaterial substances called angels, in themselves?
A[2] Whether it can arrive at the knowledge thereof by the knowledge of material things?
A[3] Whether God is the first object of our knowledge?
