(3) How man moves, who is composed of a spiritual and a corporeal nature.

(1) How an angel acts on an angel;
(2) How an angel acts on a corporeal nature;
(3) How an angel acts on man.
The first of these raises the question of the enlightenment and speech of the angels; and of their mutual coordination, both of the good and of the bad angels.
Concerning their enlightenment there are four points of inquiry:
(1) Whether one angel moves the intellect of another by enlightenment?
(2) Whether one angel moves the will of another?
