The sympathetic transference of thought from one mind to another, and the acquisition of knowledge of things either present or remote, without the aid of the external senses, are phenomena known as far back as history has any records. Such phenomena are wonderful and mysterious, but not more so than the generation of animal life or the appearance of a rainbow in the sky--subjects from which science has removed much of the mystery. Trans-corporeal or non-sensual perception has also been investigated, its laws established, its anatomical and physiological foundation explained, its range of power determined, its vast powers and utilities illustrated, and its method of development and culture made known. But of all this the mind-reading sciolists know nothing and have not attempted to learn anything. They are attitudinizing on the outer steps of the temple of science, before the gazing multitude, instead of penetrating the interior of the temple, where the multitude do not follow. The exhibiting mind-readers start with the assumption that matter does all, and that the ample literature in which the powers of the soul are recorded, demonstrated, and explained is unworthy of notice. Thus they place themselves in sympathy with the prevalent ignorance on such subjects, and the dogmatism of a certain class of scientists. The dogmatism of this hypothesis cannot be maintained by any careful and conscientious inquirer, who knows how to conduct an investigation. When the psychic faculties are well developed, as they certainly are in Mr. Bishop, the inquirer cannot fail to realize that ideas are developed by transference in the mind without the slightest opportunity of being instructed by muscular movements. Hence Mr. Bishop finally admits the direct transference of thought from mind to mind; but instead of presenting it boldly as a positive and thousand times demonstrated act, he still leans upon the letter of Dr. Carpenter, which represents him as learning the thoughts of others, by "careful study of the indications unconsciously given by the subject." He confesses that he once stood upon the strictly material hypothesis, from which he has advanced to the psychic doctrine he now maintains, and adds, "Where I am may be only a stopping, not an abiding, place." Very true; the remark is honorable to his candor. He should advance a great deal farther; but he would not have stopped at either position if he had taken pains to learn what was already known and published a quarter of a century, or even what was known several centuries, before he began. If he would even now read Professor Gregory's "Letters on Animal Magnetism" and the "Manual of Psychometry," published in Boston, he might make a new departure, might understand the vast extent of his own powers, which he has not yet developed, and show to those whom he has already astonished that there is much more in the mysteries of earth and heaven than their mechanical philosophy has even suspected.
