The objection to Psychical Research is not a verbal one; it is an objection to the separation of a class of problems from their natural habitat, an objection to the violent transplanting of a growth from its own environment. It is a protest against the notion that while the psychologist may be listened to with respect and authority in one portion of his topic, the layman and the member of the Society for Psychical Research are equally or more competent to pronounce judgments in a closely allied field. It is a protest against the view that for the comprehension of such processes as sensation and perception a course in Psychology may be useful, but that telepathy may be established by any moderately intelligent but not specially informed percipient and agent; or that the study of hallucinations is indeed a complex and difficult subject, but haunted houses, and phantasms of the living, offer a proper occupation for a leisure hour. All this is wrong and absurd; and yet it is hardly an exaggeration to declare that a majority of those who profess a deep interest in, and express an opinion about the one group of topics, would be surprised to have demanded of them a familiarity with the data of Psychology as a prerequisite to an intelligent coöperation in Psychical Research. If the problems of Psychical Research, or that portion of the problems in which investigation seems profitable, are ever to be illuminated and exhibited in an intelligible form, it will only come about when they are investigated by the same methods and in the same spirit as are other psychological problems, when they are studied in connection with and as a part of other general problems of normal and abnormal Psychology. Whether this is done under the auspices of a society or in the psychological laboratories of universities is, of course, a detail of no importance. It is important, however, what the trend, and the spirit, and the method, and the purpose of the investigation may be; as it is equally important, what may be the training, and the capabilities, and the resources, and the originality, and the scholarship of the investigators.
