Such ghosts ought to excite no more terror than a twinge of rheumatism, or a nervous headache. There can be no doubt, however, that, in our minds or bodies, there are powers latent, or nearly latent, in the ordinary healthy man, which, in some peculiar constitutions, or under the influence of certain agents, or certain classes of disease, become active, and develop themselves in an extraordinary way. It is not very uncommon to find people who have acquired intuitive perception of each other’s current thoughts, beyond what can be ascribed to community of interests, or comprehension of character. Zschokke, the German writer and teacher, is a peculiarly honorable and unimpeachable witness. What he affirms, as of his own knowledge, we have no right to disbelieve. Many of us have read the marvelous account given by him of his sudden discovery, that he possessed the power in regard to a few people—by no means in regard to all—of knowing, when he came near to them, not only their present thoughts, but much of what was in their memories. The details will be found in his Autobiography, which, being translated, has become a common book among us. When, for the first time, while conversing with some person, he acquired a sense of power over the secrets of that person’s past life, he gave, of course, little heed to his sensation. Afterward, as from time to time the sense recurred, he tested the accuracy of his impressions, and was alarmed to find that, at certain times, and in regard to certain persons, the mysterious knowledge was undoubtedly acquired. Once when a young man at the table with him was dismissing very flippantly all manner of unexplained phenomena as the gross food of ignorance and credulity, Zschokke requested to know what he would say if he, a stranger, by aid of an unexplained power, should be able to tell him secrets out of his past life. Zschokke was defied to do that; but he did it. Among other things he described a certain upper room, in which there was a certain strong box, and from which certain moneys, the property of his master, had been abstracted by that young man; who, overwhelmed with astonishment, confessed the theft. Many glimmerings of intuition, which at certain times occur in the experience of all of us, and seem to be something more than shrewd or lucky guesses, may be referred to the same power which we find, in the case just quoted, more perfectly developed. Nothing supernatural, but a natural gift, imperceptible to us in its familiar, moderate, and healthy exercise, brought first under our notice when some deranged adjustment of the mind has suffered it to grow into excess—to be, if we may call it so, a mental tumor. We may now come to a new class of mysteries—which are receiving, for the first time in our own day, a rational solution.
