Of the Nature of the Soul.
15. (1) Every body is in a place; the incorporeal in itself is not in a
place, any more than the things which have the same nature as it.
16. (1) The incorporeal in itself, by the mere fact of its being
superior to every body and to every place, is present everywhere
without occupying extension, in an indivisible manner.
17. (1) The incorporeal in itself, not being present to the body in a
local manner, is present to the body whenever it pleases, that is, by
inclining towards it so far as it is within its nature to do so. Not
being present to the body in a local manner, it is present to the body
by its disposition.
18. (1) The incorporeal in itself does not become present to the body
in "being" nor in hypostatic form of existence. It does not mingle with
the body. Nevertheless, by its inclination to the body, it begets and
communicates to it a potentiality capable of uniting with the body.
Indeed the inclination of the incorporeal constitutes a second nature
(the irrational soul), which unites with the body.
19. (1) The soul has a nature intermediary between the "being" that is
indivisible, and the "being" that is divisible by its union with the
bodies. Intelligence is a "being" absolutely indivisible; the bodies
alone are divisible; but the qualities and the forms engaged in matter
are divisible by their union with the bodies.
20. (2) The things that act upon others do not act by approximation and
by contact. It is only accidentally when this occurs (that they act by
proximity and contact).
