It is said that magicians and sorcerers themselves, when they fall into the hands of judges and inquisitors, are often the first to maintain that magic and sorcery are merely imaginary, and the effect of popular prejudices and errors. Upon that footing, Satan would destroy himself, and overthrow his own empire, if he were thus to decry magic, of which he is himself the author and support. If the magicians really, and of their own good will, independently of the demon, make this declaration, they betray themselves most lightly, and do not make their cause better; since the judges, notwithstanding their disavowal, prosecute them, and always punish them without mercy, being well persuaded that it is only the fear of execution and the hope of remaining unpunished which makes them say so. But would it not rather be a stratagem of the evil spirit,[115] who endeavors to render the reality of magic doubtful, to save from punishment those who are accused of it, and to impose on the judges, and make them believe that magicians are only madmen and hypochondriacs, worthy rather of compassion than chastisement? We must then return to the deep examination of the question, and prove that magic is not a chimera, neither has it aught to do with reason. We can neither rest on a sure foundation, nor derive any certain argument for or against the reality of magic, either from the opinion of pretended _esprits forts_, who deny because they think proper to do so, and because the proofs of the contrary do not appear to them sufficiently clear or demonstrative; nor from the declaration of the demon, of magicians and sorcerers, who maintain that magic and sorcery are only the effects of a disturbed imagination; nor from minds foolishly and vainly prejudiced on the subject, that these declarations are produced simply by the fear of punishment; nor by the subtilty of the malignant spirit, who wishes to mask his play, and cast dust in the eyes of the judges and witnesses, by making them believe that what they regard with so much horror, and what they so vigorously prosecute, is anything but a punishable crime, or at least a crime deserving of punishment. We must then prove the reality of magic by the Holy Scriptures, by the authority of the Church, and by the testimony of the most grave and sensible writers; and, lastly, show that it is not true that the most famous parliaments acknowledge neither sorcerers nor magicians.
