pious physicians, making use of such proper remedies as their skill teaches them, and having an honest faith, that the goods of nature intended for the use and benefit of man, if received by the patient with the same good faith, is above the power of the devil to frustrate, may not improperly be called natural magicians. These arguments of mine I shall now take leave to back by experience. Besides, what we have urged from reason, concerning the power of natural magic, we shall only subjoin, that divines themselves hold that natural magic, and also natural divinations and prophecies, are proved by quotations from that venerable writ which is their guide; and bring proofs from the same also, that by natural magic demons are also cast forth, but not all kinds of demons, and so many works of efficacy are wrought by natural magic: they tell you, such was the Pythonissa that raised the apparition to Saul, which appeared in a body of wind and air. Thus, if a person by natural magic should cast out demons, it does not follow that this was also from divine magic; and if demons are cast out by natural magic, by one that is in the fear of God, it does not follow that he is a true magician of God; but if it exorbitates to demoniacal, then it is condemned: and when natural magic keeps within its bounds, the divines tell us it is not condemned in the venerable book, which is the Christian's sure guide. But, inasmuch as the lawfulness even of natural magic has been called in question by others, I shall, in an Appendix joined to this treatise, examine that matter, both according to the reasons of our English laws, and according to the best stated rules of casuistry that I am a master of; still submitting my judgment to the superior judgment of those who are professed divines and lawyers; and if my opinions prove erroneous, I am willing to retract them; and therefore, in this place, there remains nothing farther for me to do, but only, as I have shown, on the one hand, how natural magic, and its powerful operations, are proved by reason, to show, on the other hand, how far reason in these cases is likewise backed and supported by well-evidenced practice, and notorious experience. And to do this, after having mentioned one memorable instance, which I refer the reader to in the body of the book, concerning the performances of Mr. Greatrix, to which a Lord Orrery was a witness, in Ireland; I shall, to avoid prolixity, bring the other testimonials of practice, from the success which our Duncan Campbell himself has had in this way on other occasions.
