says the same philosopher, in another passage.[523]
They objected to it for several good reasons. 1. “It is extremely difficult to distinguish a good dæmon from a bad one,” says Iamblichus. 2. If a human soul succeeds in penetrating the density of the earth’s atmosphere—always oppressive to her, often hateful—still there is a danger the soul is unable to come into proximity with the material world without that she cannot avoid; “departing, she retains something,” that is to say, contaminating her purity, for which she has to suffer more or less after her departure. Therefore, the true theurgist will avoid causing any more suffering to this pure denizen of the higher sphere than is absolutely required by the interests of humanity. It is only the practitioner of black magic who compels the presence, by the powerful incantations of necromancy, of the tainted souls of such as have lived bad lives, and are ready to aid his selfish designs. Of intercourse with the Augoeides, through the mediumistic powers of subjective mediums, we elsewhere speak. The theurgists employed chemicals and mineral substances to chase away evil spirits. Of the latter, a stone called Μνίζουριν was one of the most powerful agents.
“When you shall see a terrestrial demon approaching,
Exclaim, and sacrifice the stone Mnizurin,”
exclaims a Zoroastrian oracle (Psel., 40).
And now, to descend from the eminence of theurgico-magian poetry to the “unconscious” magic of our present century, and the prose of a modern kabalist, we will review it in the following:
In Dr. Morin’s Journal de Magnétisme, published a few years since in Paris, at a time when the “table-turning” was raging in France, a curious letter was published.
“Believe me, sir,” wrote the anonymous correspondent, “that there are no spirits, no ghosts, no angels, no demons enclosed in a table; but, all of these can be found there, nevertheless, for that depends on our own wills and our imaginations.... This MENSAbulism[524] is an ancient phenomenon ... misunderstood by us moderns, but natural, for all that, and which pertains to physics and psychology; unfortunately, it had to remain incomprehensible until the discovery of electricity and heliography, as, to explain a fact of spiritual nature, we are obliged to base ourselves on a corresponding fact of a material order....
“As we all know, the daguerreotype-plate may be impressed, not only by objects, but also by their reflections. Well, the phenomenon in question, which ought to be named mental photography, produces, besides realities, the dreams of our imagination, with such a fidelity that very often we become unable to distinguish a copy taken from one present, from a negative obtained of an image....
“The magnetization of a table or of a person is absolutely identical in its results; it is the saturation of a foreign body by either the intelligent vital electricity, or the thought of the magnetizer and those present.”
