to prevent Hector, he did not prevent him; but out of anger (and it depended on himself to be angry or not) did not keep back the fire, and was a concurring cause. Now the devil, being possessed of free-will, was able both to repent and to steal; and it was he who was the author of the theft, not the Lord, who did not prevent him. But neither was the gift hurtful, so as to require that prevention should intervene. But if strict accuracy must be employed in dealing with them, let them know, that that which does not prevent what we assert to have taken place in the theft, is not a cause at all; but that what prevents is involved in the accusation of being a cause. For he that protects with a shield is the cause of him whom he protects not being wounded; preventing him, as he does, from being wounded. For the demon of Socrates was a cause, not by not preventing, but by exhorting, even if (strictly speaking) he did not exhort. And neither praises nor censures, neither rewards nor punishments, are right, when the soul has not the power of inclination and disinclination, but evil is involuntary. Whence he who prevents is a cause; while he who prevents not judges justly the soul’s choice. So in no respect is God the author of evil. But since free choice and inclination originate sins, and a mistaken judgment sometimes prevails, from which, since it is ignorance and stupidity, we do not take pains to recede, punishments are rightly inflicted. For to take fever is involuntary; but when one takes fever through his own fault, from excess, we blame him. Inasmuch, then, as evil is involuntary,--for no one prefers evil as evil; but induced by the pleasure that is in it, and imagining it good, considers it desirable;--such being the case, to free ourselves from ignorance, and from evil and voluptuous choice, and above all, to withhold our assent from those delusive phantasies, depends on ourselves. The devil is called “thief and robber;” having mixed false prophets with the prophets, as tares with the wheat. “All, then, that came before the Lord, were thieves and robbers;” not absolutely all men, but all the false prophets, and all who were not properly sent by Him. For the false prophets possessed the prophetic name dishonestly, being prophets, but prophets of the liar. For the Lord says, “Ye are of your father the devil; and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own; for he is a liar, and the father of it.”[955]
