s the Philosopher says
in the second book of the Metaphysics, and he affirms their existence.
Though we have not any perception of them from which our knowledge can
begin, yet some light from their most vivacious essence shines upon
our intellect, inasmuch as we perceive the above-mentioned reasons and
many others, even as he who has the eyes closed affirms the air to be
luminous, because of some little brightness or ray of light which
passes through the pupils; as it is with the bat, for not otherwise
are the eyes of the intellect closed, so long as the soul is bound and
prisoned by the organs of our body.

CHAPTER VI.

It has been said that, through defective instruction, the ancients saw
not the Truth concerning the Spiritual Creatures, although the people
of Israel were in part instructed by their Prophets, through whom by
many modes of speech and in many ways God had spoken to them, as the
Apostle says. But we are therein instructed by Him who came from God,

had commanded His Angels that they should minister unto Him and should
serve Him. Wherefore, it is evident to us that these creatures are in
a very great number; since His Spouse and Secretary, Holy Church, of
whom Solomon says: "Who is this that cometh forth from the Desert,
full of those things which give delight, leaning upon her friend?"
says, believes, and preaches these most noble creatures to be almost
innumerable; and She divides them into three Hierarchies, that is to
say, three holy, or rather Divine, Principalities: and each Hierarchy
has three orders, so that nine orders
