The word clairvoyance has acquired a decidedly sinister meaning in most people's minds. It is associated with professional spiritistic mediums, who lay claim to supernatural powers which they are ready, at a moment's notice, to exercise for all who are credulous enough to pay the fee they demand. Newspapers throughout the country daily contain advertisements of clairvoyants of this type, arrant humbugs, most of them, but often able, through cunningly acquiring information regarding their "sitters'" lives and family relationships, to persuade their victims that while "entranced" they are actually in contact with the "spirit world." Repeated exposures of their fraudulent methods have not driven them out of business, but have inspired a widespread and healthy distrust of their pretensions. Nevertheless, it would be rash to conclude, as many of us do, that there is no such thing as genuine clairvoyance, by which is meant the ability to perceive distant scenes and events as if one were bodily present at the place of their occurrence. That such a faculty exists, although usable only on rare occasions, and that there is nothing in the least supernatural about it, are facts definitely established by the scientifically trained investigators who have been diligently attacking this and other psychical problems the past twenty-five years. Their researches have made it evident that in order to explain genuine clairvoyant phenomena it is not necessary to postulate the intervention of "spirits," or the flight through space of the clairvoyant's "astral body." At most, clairvoyance is simply a special form of telepathy, differing in degree but not in kind from the phenomena discussed in the preceding chapter. There is absolutely no evidence to justify the hypothesis of so-called "independent clairvoyance," advocated by occultists of every shade of spiritistic belief, and utilized by unscrupulous tricksters to dazzle the imagination of their dupes. On the other hand, as I hope to make convincingly clear, there is plenty of proof that the scenes which the true clairvoyant perceives, and is frequently able to describe with graphic detail, are in reality only mental images, visual hallucinations, developed by the same process that enables any ordinary telepathic message to be apprehended. It must be acknowledged, however, that the telepathic connection is sometimes extremely difficult to trace; as, for example, in the few indisputable instances, reported by Professor James and other trustworthy investigators, in which the services of clairvoyants have been successfully invoked to find the bodies of persons drowned or otherwise accidentally killed under circumstances seemingly precluding any one from having knowledge of the place or manner of their death. A typical case of the kind occurred a few years ago in connection with the mysterious death of a New Hampshire girl, Miss Bertha Huse, of Enfield, who was drowned in Mascoma Lake.
