And it is no wonder that the devil can do this by his own natural power; since any man by himself, being awake and having the use of his reason, can voluntarily draw from his repositories the images he has retained in them; in such a way that he can summon to himself the images of whatsoever things he pleases. And this being granted, it is easy to understand the matter of excessive infatuation in love.
Now there are two ways in which devils can, as has been said, raise up this kind of images. Sometimes they work without enchaining the human reason, as has been said in the matter of temptation, and the example of voluntary imagination. But sometimes the use of reason is entirely chained up; and this may be exemplified by certain naturally defective persons, and by madmen and drunkards. Therefore it is no wonder that devils can, with God’s permission, chain up the reason; and such men are called delirious, because their senses have been snatched away by the devil. And this they do in two ways, either with or without the help of witches. For Aristotle, in the work we have quoted, says that anyone who lives in passion is moved by only a little thing, as a lover by the remotest likeness of his love, and similarly with one who feels hatred. Therefore devils, who have learned from men’s acts to which passions they are chiefly subject, incite them to this sort of inordinate love or hatred, impressing their purpose on men’s imagination the more strongly and effectively, as they can do so the more easily. And this is the more easy for a lover to summon up the image of his love from his memory, and retain it pleasurably in his thoughts.
But they work by witchcraft when they do these things through and at the instance of witches, by reason of a pact entered into with them. But it is not possible to treat of such matters in detail, on account of the great number of instances both among the clergy and among the laity. For how many adulterers have put away the most beautiful wives to lust after the vilest of women!
We know of an old woman who, according to the common account of the brothers in that monastery even up to this day, in this manner not only bewitched three successive Abbots, but even killed them, and in the same way drove the fourth out of his mind. For she herself publicly confessed it, and does not fear to say: I did so and I do so, and they are not able to keep from loving me because they have eaten so much of my dung—measuring off a certain length on her arm. I confess, moreover, that since we had no case to prosecute her or bring her to trial, she survives to this day.
It will be remembered that it was said that the devil invisibly lures a man to sin, not only by means of persuasion, as has been said, but also by the means of disposition. Although this is not very pertinent, yet be it said that by a similar admonition of the disposition and humours of men, he renders some more disposed to anger, or concupiscence, or other passions. For it is manifest that a man who has a body so disposed is more prone to concupiscence and anger and such passions; and when they are aroused, he is more apt to surrender to them. But because it is difficult to quote precedents, therefore an easier method must be found of declaring them for the admonition of the people. And in the Second Part of this book we treat of the remedies by which men so bewitched can be set free.
The Method of Preaching to the People about Infatuate Love.
Concerning what has been said above, a preacher asks this question: Is it a Catholic view to maintain that witches can infect the minds of men with an inordinate love of strange women, and so inflame their hearts that by no shame or punishment, by no words or actions can they be forced to desist from such love; and that similarly they can stir up such hatred between married couples that they are unable in any way to perform the procreant functions of marriage; so that, indeed, in the untimely silence of night, they cover great distances in search of mistresses and irregular lovers?
As to this matter, he may, if he wishes, find some arguments in the preceding question. Otherwise, it need only be said that there are difficulties in those questions on account of love and hate. For these passions invade the will, which is in its own act always free, and not to be coerced by any creature except God, Who can govern it. From which it is clear that neither the devil nor a witch working by his power can force a man’s will to love or to hate. Again, since the will, like the understanding, exists subjectively in the soul, and He alone can enter into the soul Who created it, therefore this question presents many difficulties in the matter of unravelling the truth of it.
But notwithstanding this, we must speak first of infatuation and hatred, and secondly about the bewitching of the generative power. And as to the first, although the devil cannot directly operate upon the understanding and will of man, yet, according to all the learned Theologians in the 2nd Book of Sentences, on
