On the Mysteries
IV, Chapter I (2)
These inform us what ought to be done, and from what it is fit to abstain. They also give assistance to just works, but impede such as are unjust; and as many endeavour to take away unjustly the property of others, or basely to injure or destroy some one, they cause these to suffer the same things as they have done to others. But there is, likewise, another most irrational genus of dæmons, which is without judgment, and is allotted only one power, through an arrangement by which each of these dæmons presides over one work alone. As therefore, it is the province of a sword to cut, and to do nothing else than this, thus also of the spirits which are distributed in the universe, according to the partible necessity of nature, one kind divides, but another collects, things which are generated. This, however, is known from the phænomena. For the Charonean spiracles, as they are called, emit from themselves a certain spirit, which is able to corrupt promiscuously every thing that falls into them. Thus, therefore, of certain invisible spirits, each is allotted a different power, and is alone adapted to do that which it is ordained to perform. He, therefore, who turns from their natural course things which contribute to the universe in an orderly manner, and illegitimately performs a certain thing, in this case receives the injury arising from that which he uses badly. This, however, pertains to another mode of discussion.

On Divine Names, Caput IV (23)
Then, are they evil to themselves or to others? If to themselves, they also destroy themselves; but if to others, how destroying, or what destroying?-...
(23) But, neither are the demons evil by nature; for, if they are evil by nature, neither are they from the Good, nor amongst things existing; nor, in fact, did they change from good, being by nature, and always, evil. Then, are they evil to themselves or to others? If to themselves, they also destroy themselves; but if to others, how destroying, or what destroying?--Essence, or power, or energy? If indeed Essence, in the first place, it is not contrary to nature; for they do not destroy things indestructible by nature, but things receptive of destruction. Then, neither is this an evil for every one, and in every case; but, not even any existing thing is destroyed, in so far as it is essence and nature, but by the defect of nature's order, the principle of harmony and proportion lacks the power to remain as it was. But the lack of strength is not complete, for the complete lack of power takes away even the disease and the subject; and such a disease will be even a destruction of itself; so that, such a thing is not an evil, but a defective good, for that which has no part of the Good will not be amongst things which exist. And with regard to the destruction of power and energy the principle is the same. Then, how are the demons, seeing they come into being from God, evil? For the Good brings forth and sustains good things. Yet they are called evil, some one may say. But not as they are (for they are from the Good, and obtained a good being), but, as they are not, by not having had strength, as the Oracles affirm, "to keep their first estate." For in what, tell me, do we affirm that the demons become evil, except in the ceasing in the habit and energy for good things Divine? Otherwise, if the demons are evil by nature, they are always evil; yet evil is unstable. Therefore, if they are always in the same condition, they are not evil; for to be ever the same is a characteristic of the Good. But, if they are not always evil, they are not evil by nature, but by wavering from the angelic good qualities. And they are not altogether without part in the good, in so far as they both are, and live and think, and in one word--as there is a sort of movement of aspiration in them. But they are said to be evil, by reason of their weakness as regards their action according to nature. The evil then, in them, is a turning aside and a stepping out of things befitting themselves, and a missing of aim, and imperfection and impotence, and a weakness and departure, and falling away from the power which preserves their integrity in them. Otherwise, what is evil in demons? An irrational anger--a senseless desire--a headlong fancy.--But these, even if they are in demons, are not altogether, nor in every respect, nor in themselves alone, evils. For even with regard to other living creatures, not the possession of these, but the loss, is both destruction to the creature, and an evil. But the possession saves, and makes to be, the nature of the living creature which possesses them. The tribe of demons then is not evil, so far as it is according to nature, but so far as it is not; and the whole good which was given to them was not changed, but themselves fell from the whole good given. And the angelic gifts which were given to them, we by no means affirm that they were changed, but they exist, and are complete, and all luminous, although the demons themselves do not see, through having blunted their powers of seeing good. So far as they are, they are both from the Good, and are good, and aspire to the Beautiful and the Good, by aspiring to the realities, Being, and Life, and Thought; and by the privation and departure and declension from the good things befitting them, they are called evil, and are evil as regards what they are not: and by aspiring to the non-existent, they aspire to the Evil.

(8) And that the devil so spoken of by the Barbarian philosophy, the prince of the demons, is a wicked spirit, Plato asserts in the tenth book of the Laws, in these words: "Must we not say that spirit which pervades the things that are moved on all sides, pervades also heaven? Well, what? One or more? Several, say I, in reply for you. Let us not suppose fewer than two - that which is beneficent, and that which is able to accomplish the opposite." Similarly in the Phoedrus he writes as follows: "Now there are other evils. But some demon has mingled pleasure with the most things at present." Further, in the tenth book of the Laws, he expressly emits that apostolic sentiment, "Our contest is not with flesh and blood, but principalities, with powers, with the spiritual things of those which are in heaven;" writing thus: "For since we are agreed that heaven is full of many good beings; but it is also full of the opposite of these, and more of these; and as we assert such a contest is deathless, and requiring marvellous watchfulness."
