City of God

What, then, is the difference between good and evil demons? For the Platonist Apuleius, in a treatise on this whole subject, while he says a great deal about their aerial bodies, has not a word to say of the spiritual virtues with which, if they were good, they must have been endowed. Not a word has he said, then, of that which could give them happiness; but proof of their misery he has given, acknowledging that their mind, by which they rank as reasonable beings, is not only not imbued and fortified with virtue so as to resist all unreasonable passions, but that it is somehow agitated with tempestuous emotions, and is thus on a level with the mind of foolish men. His own words are: “It is this class of demons the poets refer to, when, without serious error, they feign that the gods hate and love individuals among men, prospering and ennobling some, and opposing and distressing others. Therefore pity, indignation, grief, joy, every human emotion is experienced by the demons, with the same mental disturbance, and the same tide of feeling and thought. These turmoils and tempests banish them far from the tranquility of the celestial gods.” Can there be any doubt that in these words it is not some inferior part of their spiritual nature, but the very mind by which the demons hold their rank as rational beings, which he says is tossed with passion like a stormy sea? They cannot, then, be compared even to wise men, who with undisturbed mind resist these perturbations to which they are exposed in this life, and from which human infirmity is never exempt, and who do not yield themselves to approve of or perpetrate anything which might deflect them from the path of wisdom and law of rectitude. They resemble in character, though not in bodily appearance, wicked and foolish men. I might indeed say they are worse, inasmuch as they have grown old in iniquity, and incorrigible by punishment. Their mind, as Apuleius says, is a sea tossed with tempest, having no rallying point of truth or virtue in their soul from which they can resist their turbulent and depraved emotions.
