At such times a corps is formed of workmen, furnished with various implements for the work. Some collect facts from which they hope to build up a theory; others propose theories by whose light they hope to detect valuable facts; a large number are engaged in circulating reports of these labors; a larger in attempting to prove them invalid and absurd. These last are of some use by shaking the canker-worms from the trees; all are of use in elucidating truth. Such a course of study has the civilized world been engaged in for some years back with regard to what is called Animal Magnetism. We say the civilized world, because, though a large portion of the learned and intellectual, to say nothing of the thoughtless and the prejudiced, view such researches as folly, yet we believe that those prescient souls, those minds more deeply alive, which are the life of this and the parents of the next era, all, more or less, consciously or unconsciously, share the belief in such an agent as is understood by the largest definition of animal magnetism; that is, a means by which influence and thought may be communicated from one being to another, independent of the usual organs, and with a completeness and precision rarely attained through these. For ourselves, since we became conscious at all of our connection with the two forms of being called the spiritual and material, we have perceived the existence of such an agent, and should have no doubts on the subject, if we had never heard one human voice in correspondent testimony with our perceptions. The reality of this agent we know, have tested some of its phenomena, but of its law and its analysis find ourselves nearly as ignorant as in earliest childhood. And we must confess that the best writers we have read seem to us about equally ignorant. We derive pleasure and profit in very unequal degrees from their statements, in proportion to their candor, clearness of perception, severity of judgment, and largeness of view. If they possess these elements of wisdom, their statements are valuable as affording materials for the true theory; but theories proposed by them affect us, as yet, only as partially sustained hypotheses. Too many among them are stained by faults which must prevent their coming to any valuable results, sanguine haste, jealous vanity, a lack of that profound devotion which alone can win Truth from her cold well, careless classification, abrupt generalizations. We see, as yet, no writer great enough for the patient investigation, in a spirit liberal yet severely true, which the subject demands. We see no man of Shakspearian, Newtonian incapability of deceiving himself or others.
