/summa/FP/FPX/FP_Q114:
We now consider the assaults of the demons. Under this head there are five points of inquiry:
(1) Whether men are assailed by the demons?
(2) Whether to tempt is proper to the devil?
(3) Whether all the sins of men are to be set down to the assaults or temptations of the demons?
(4) Whether they can work real miracles for the purpose of leading men astray?
(5) Whether the demons who are overcome by men, are hindered from making further assaults?
