Between the organized effort and well-recognized plan of action of science and the chaotic movements of the untutored mind, there is a marked contrast. The savage, like the child, constantly meets with the unexpected; every experience lying outside his narrow beaten track stirs him with a shock and often fills him with fear--the handmaid of ignorance. He is apt to picture nature as a fearful monster, and to people the world with tyrannical beings. Step by step the region of the known expands, and suggests the nature of the unknown; men expect, they foresee, they predict. The apparent chaos of mutually inimical forces gives way to the profound harmony of unifying law. And yet the unknown and the borderland that separates it from the known are always near by, to tempt curiosity and the spirit of adventure.
The problem here to be considered relates to the attitude which may most properly and profitably be taken with regard to the outlying phenomena of the mind. Are they outcasts, to be treated in a spirit of charity and forbearance? Are they the true owners of the land, driven off, like the Indian before the white man, by the relentless march of civilization to a prescribed reservation? Are they the unjustly deposed and rightful heirs, soon to be restored to their kingdom by a fairer and more searching examination of their title? Or are they, gypsy-like, of obscure origin, surviving in a civilization which they are in but not of, attempting to eke out an uncertain existence by peddling relics of antiquated lore to the curious and the credulous?
The current usage of the term "Psychical Research" takes its meaning from the Society for Psychical Research, founded in England in 1882. The original programme of the society involved a systematic investigation of "that large group of debatable phenomena designated by such terms as mesmeric, psychical, and Spiritualistic." "From the recorded testimony of many competent witnesses," it is urged, "there appears to be, amidst much delusion and deception, an important body of remarkable phenomena, which are _prima facie_ inexplicable on any generally recognized hypothesis, and which, if incontestably established, would be of the highest possible value." The work of investigation of these "residual phenomena" was intrusted to six committees, who were to inquire severally into "the nature and extent of any influence which may be exerted by one mind upon another, apart from any generally recognized mode of perception;" into hypnotism, the so-called mesmeric trance, clairvoyance, and other allied phenomena; to undertake a revision of Reichenbach's researches with reference to discovering whether his "sensitives" possessed "any power of perception beyond a highly exalted sensibility of the recognized sensory organs;" to investigate the reports of apparitions at the moment of death, and of houses reputed to be haunted; to inquire into the causes and general laws of the phenomena of Spiritualism; and to collect material relative to the history of these subjects. It is the investigation of these topics from the point of view prevalent in the publications of this Society that constitutes the definition of Psychical Research. This phrase, which has come into prominence within less than a score of years, has no simple or familiar synonym; it must not be interpreted by the combined connotation of its component words, but must be accepted as the technical equivalent of the trend and content of a certain type of investigation of obscure phenomena or alleged phenomena, in most of which psychological factors are prominent.
