“To these sorcerers and witches (_mediums_), they ordinarily show themselves in a visible form, and will come to those who call them.” “As to persons subject to these sort of things, they are usually those young and tender of age, cold and imperfectly organized beings; by such we can speak with power; old men and eunuchs, and withal melancholy persons.” “All those these devils dominate over, are estranged from their natural, beings, and not infrequently become maniacs.” Our author in his chapter on the essence of souls, affirms, that “that the ancient oracles _were only the Oracles of the souls of men_,” and to be specific, he gives a long list of names. He remarks, “there were in Greece, temples known to be psychomantic, and in such places were received responses from the souls of different men. It was for this reason too, that the souls for the same reason watched over the places where the bodies of generous and noble barons had been burned.” Further along Le Loyer mentions the origin of the _power that the spirits possess of manifesting themselves to us_, but our author _disagrees with the modern theories that makes them derive their power from the medium_, for he remarks that the spirits can act “_through their own powers_,” and are governed only by their own intelligence. “They are not off so far,” adds he, “and the distance between us and the spirits is so slight that we may easily communicate;” however, he says, meantime: “They are commanded by God and conform to his will.” Finally, he considers man as an inferior being to the spirits of the dead—in fact, he states: “The soul appears to derive nothing from another, and, as an invisible spirit, it acts with us as a passive agent, being too proud to control that which is inferior; and I deny,” says he, “that the true souls of the dead obey either charms or magical words.”
