The want of discrimination of the facts from the theories invented to explain them, is another and great source of delusion; for the majority it suffices that if the "raps" occur, or the table moves, it is sufficiently demonstrative that it is by the influence of spirits; and it is a much less difficult matter to them to believe that the phenomena arises from supernatural than natural agency.
Certain luminous phenomena, phosphorescent flames, luminous clouds, glistening stars, &c., have been observed when the spirit-manifestations have occurred in profound darkness. These appearances were dependent upon a disordered condition of the eye, which will be fully dwelt upon in a subsequent part of this work.
The irregular and violent movements of the furniture which occurred when the séances were held in darkened apartments, were the result of the most palpable collusion. There were certain movements of the tables, however, around which the experimenters sat when eliciting the spirit-rappings, that could not be attributed to this source; and an examination of these motions showed that if several persons arranged themselves around a table, and rested their hands slightly upon it, after a longer or shorter period motion would occur, which was to a great extent under the control of the will, although the experimenters were not aware that they exerted any force whatever upon the table; and further, it was ascertained that a table thus set in motion would respond by rapping with the legs, to questions propounded to it, and that with a facility equal to the most perfect "medium."
This interesting phenomenon soon attracted considerable attention, for it was certain that neither collusion nor wilful deception were concerned in it; and it could be produced by persons who did not pretend to the character of "mediums;" indeed, out of a company of several individuals it was pretty certain that some could be found capable of inducing the phenomenon.
The "Rappites" looked upon it simply as another and more general manifestation of the spirit-world; others, imbued with the pseudo-scientific dogmas of animal magnetism, odylism, &c., sought an explanation in the principles of their respective theories; some regarded it as the result of Satanic agency; and lastly, those best capable of judging on the question, looked upon the motion as the result of muscular force exerted unconsciously by the experimenters, and in accordance with certain well-known laws of muscular and mental action.
The doctrine of Satanic agency has excited great attention in this country, from the fact of its being propounded and advocated by certain clergymen of our Established Church, who not content with regarding it as one of those "great wonders" which are to prelude the reign of Anti-christ, have even sought by this agency to verify the truths of the immortality of the soul, eternity, the existence of a hell; thus seeking a confirmation of the Scripture from the devil himself, and comically identifying themselves with the principles so pithily expressed by Ralpho:—
"Those principles I've quoted late,
Prove that the godly may allege
For anything their privilege,
And to the devil himself may go,
If they have motives thereunto:
For as there is a war between
The dev'l and them, it is no sin
If they, by subtle stratagem,
Make use of him, as he does them."[56]
The answer to this explication, as well as to those other explications based on the doctrines of the "Rappites," and the principles of the pseudo-sciences, is found in the simple fact, that if care be taken to ascertain the sources of motion which arise from the experimenters themselves, and to obviate their influence in the experiment, neither movements nor responses occur; and by a careful examination of the conditions requisite for the perfection of the experiment, and an experimental illustration of them, we arrive at the conclusion that "table-moving" and "table-talking" are the result solely of muscular action exercised unconsciously under the influence of certain expectant ideas.
If we proceed in the examination of this question as in that of every other physical question, by seeking the conditions requisite for the fulfilment of the experiment, and examining their nature, we observe that the position of the persons who perform it is one that would give rise to certain easily understood and comprehensible results. The hands are placed upon the table in such a position that the experimenter exercises the least degree of pressure of which he can be conscious, and in this position they are kept for a longer or shorter period, but generally averaging from twenty to thirty minutes. Whether the individual be sitting or standing, the protracted exertion of the muscles to keep the hand in so constrained a position, gives rise to considerable fatigue, which is manifested by the usual painful sensations in the over-exercised parts; and these sensations have been sagely compared by the advocates of the pseudo-sciences to those experienced by electric or electro-magnetic currents. As the muscular fatigue and the painful state of tension into which the muscles are thrown increase, the sensations by which we judge of the amount of pressure exercised upon a given object diminishes, and unless the degree of pressure exercised is checked by information derived through some other sense, it goes on ever increasing in a direct ratio until the whole weight of the hand, the arm, and even the shoulders of the person so standing is unconsciously thrown upon the table, and a degree of force exercised, which is sufficient to induce the movements we witness in the table experimented on.
