“But Mr. Crookes mentioned another eminent scholar, Thury, of Geneva, professor of natural history, who was a brother-investigator with Gasparin in the phenomena of the Valleyres. This professor contradicts point-blank the assertions of his colleague.
“The first and most necessary condition”, says Gasparin, “is the will of the experimenter; without the will, one would obtain nothing; you can form the chain (the circle) for twenty-four hours consecutively, without obtaining the least movement.”
The above proves only that de Gasparin makes no different between phenomena purely magnetic, produced by the persevering will of the sitters among whom there may be not even a single medium, developed or undeveloped, and the so-called spiritual ones.
While the first can be produced consciously by nearly every person, who has a firm and determined will, the latter overpowers the sensitive very often against his own consent, and always acts independently of him.
The mesmerizer wills a thing, and if he is powerful enough, that thing is done. The medium, even if he had an honest purpose to succeed, may get no manifestations at all; the less he exercises his will, the better the phenomena; the more he feels anxious, the less he is likely to get anything; to mesmerize requires a positive nature, to be a medium a perfectly passive one.
This is the Alphabet of Spiritualism, and no medium is ignorant of it.”
