However, to collect human semen from one person and to transfer it to another implies certain local actions. But devils cannot locally move bodies from place to place. And this is the argument they put forward. The soul is purely a spiritual essence, so is the devil: but the soul cannot move a body from place to place except it be that body in which it lives and to which it gives life: whence if any member of the body perishes it becomes dead and immovable. Therefore devils cannot move a body from place to place, except it be a body to which they give life. It has been shown, however, and is acknowledged that devils do not bestow life on anybody, therefore they cannot move human semen locally, that is, from place to place, from body to body.
Moreover, every action is performed by contact, and especially the act of generation. But it does not seem possible that there can be any contact between the demon and human bodies, since he has not actual point of contact with them. Therefore he cannot inject semen into a human body, and therefore since this needs a certain bodily action, it would seem that the devil cannot accomplish it.
Besides, devils have no power to move those bodies which in a natural order are more closely related to them, for example the heavenly bodies, therefore they have no power to move those bodies which are more distant and distinct from them. The major is proved, since the power that moves and the movement are one and the same thing according to Aristotle in his Physics. It follows, therefore, that devils who move heavenly bodies must be in heaven, which is wholly untrue, both in our opinion, and in the opinion of the Platonists.
Moreover, S. Augustine, On the Trinity, III, says that devils do indeed collect human semen, by means of which they are able to produce bodily effects; but this cannot be done without some local movement, therefore demons can transfer semen which they have collected and inject it into the bodies of others. But, as Walafrid Strabo says in his commentary upon Exodus 7:11: And Pharaoh called the wise men and the magicians: Devils go about the earth collecting every sort of seed, and can by working upon them broadcast various species. See also the gloss on those words (Pharaoh called). And again in Genesis 6 the gloss makes two comments on the words: And the sons of God saw the daughters of men. First, that by the sons of God are meant the sons of Seth, and by the daughters of men, the daughters of Cain. Second, that Giants were created not by some incredible act of men, but by certain devils, which are shameless towards women. For the Bible says, Giants were upon the earth. Moreover, even after the Flood the bodies not only of men, but also of women, were preeminently and incredibly beautiful.
Answer. For the sake of brevity much concerning the power of the devil and his works in the matter of the effects of witchcraft is left out; for the pious reader either accepts it as proved, or he may, if he wish to inquire, find every point clearly elucidated in the second Book of Sentences, 5. For he will see that the devils perform all their works consciously and voluntarily; for the nature that was given them has not been changed. See Dionysius131 in his fourth chapter on the subject; their nature remained intact and very splendid, although they cannot use it for any good purpose.
And as to their intelligence, he will find that they excel in three points of understanding, in their age-long experience, and in the revelation of the higher spirits. He will find also how, through the influence of the stars, they learn the dominating characteristics of men, and so discover that some are more disposed to work witchcraft than others, and that they molest these chiefly for the purpose of such works.
And as to their will, the reader will find that it cleaves unchangeably to evil, and that they continuously sin in pride, envy, and gross covetousness; and that God, for his own glory, permits them to work against His will. He will also understand how with these two qualities of intellect and will devils do marvels, so that there is no power in earth which can be compared to them: Job 41. There is no power on the earth which can be compared with him, who was created that he should fear no one. But here the gloss says, Although he fears no one he is yet subject to the merits of the Saints.
He will find also how the devil knows the thoughts of our hearts; how he can substantially and disastrously metamorphose bodies with the help of an agent; how he can move bodies locally, and alter the outward and inner feelings to every conceivable extent; and how he can change the intellect and will of a man, however indirectly.
For although all this is pertinent to our present inquiry, we wish only to
