The answer to the fourth objection. The work of God can be destroyed by the work of the devil in accordance with what we are now saying with reference to the power and effects of witchcraft. But since this can only be by the permission of God, it does not at all follow that the devil is stronger than God. Again, he cannot use so much violence as he wishes to harm the works of God, because if he were unrestricted he would utterly destroy all the works of God.
The answer to the fifth objection may be clearly stated thus: The planets and stars have no power to coerce and compel devils to perform any actions against their will, although seemingly demons are readier to appear when summoned by magicians under the influence of certain stars. It appears that they do this for two reasons. First, because they know that the power of that planet will aid the effect which the magicians desire. Secondly, They do this in order to deceive men, thus making them suppose that the stars have some divine power or actual divinity, and we know that in days of old this veneration of the stars led to the vilest idolatry.
With reference to the last objection, which is founded upon the argument that gold is made by alchemists, we may put forward the opinion of S. Thomas when he discusses the power of the devil and how he works: Although certain forms having a substance may be brought about by art and the power of a natural agent, as, for example, the form fire is brought about by art employed on wood: nevertheless, this cannot be done universally, because art cannot always either find or yet mix together the proper proportions, and yet it can produce something similar. And thus alchemists make something similar to gold, that is to say, in so far as the external accidents are concerned, but nevertheless they do not make true gold, because the substance of gold is not formed by the heat of fire which alchemists employ, but by the heat of the sun, acting and reacting upon a certain spot where mineral power is concentrated and amassed, and therefore such gold is of the same likeness as, but is not of the same species as, natural gold. And the same argument applies to all their other operations.
This then is our proposition: devils by their act do bring about evil effects through witchcraft, yet it is true that without the assistance of some agent they cannot make any form, either substantial or accidental, and we do not maintain that they can inflict damage without the assistance of some agent, but with such an agent diseases, and any other human passions or ailments, can be brought about, and these are real and true. How these agents or how the employment of such means can be rendered effective in cooperation with devils will be made clear in the following chapters.
Question II
If it be in accordance with the Catholic Faith to maintain that in order to bring about some effect of magic, the devil must intimately cooperate with the witch, or whether one without the other, that is to say, the devil without the witch, or conversely, could produce such an effect.
And the first argument is this: That the devil can bring about an effect of magic without the cooperation of any witch. So S. Augustine holds. All things which visibly happen so that they can be seen, may (it is believed) be the work of the inferior powers of the air. But bodily ills and ailments are certainly not invisible, nay rather, they are evident to the senses, therefore they can be brought about by devils. Moreover, we learn from the Holy Scriptures of the disasters which fell upon Job, how fire fell from heaven and striking the sheep and the servants consumed them, and how a violent wind threw down the four corners of a house so that it fell upon his children and slew them all. The devil by himself without the cooperation of any witches, but merely by God’s permission alone, was able to bring about all these disasters. Therefore he can certainly do many things which are often ascribed to the work of witches.
And this is obvious from the account of the seven husbands of the maiden Sara, whom a devil killed. Moreover, whatever a superior power is able to do, it is able to do without reference to a power superior to it, and a superior power can all the more work without reference to an inferior power. But an inferior power can cause hailstorms and bring about diseases without the help of a power greater than itself. For Blessed Albertus Magnus in his work De passionibus aeris117 says that rotten sage, if used as he explains, and thrown into running water, will arouse most fearful tempests and storms.
Moreover, it may be
