The reason for this criticism seems to be, that while one small set of students is interested in, and familiar with the themes examined in the first part (namely the psychological characteristics of certain mental states from which, in part, the doctrine of spirits is said to have arisen), that set of students neither knows nor cares anything about the matter handled in the second part. This group of students is busied with "Psychical Research," and the obscure human faculties implied in alleged cases of hallucination, telepathy, "double personality," human automatism, clairvoyance, and so on. Meanwhile anthropological readers are equally indifferent as to that branch of psychology which examines the conditions of hysteria, hypnotic trance, "double personality," and the like. Anthropologists have not hitherto applied to the savage mental conditions, out of which, in part, the doctrine of "spirits" arose, the recent researches of French, German, and English psychologists of the new school. As to whether these researches into abnormal psychological conditions do, or do not, indicate the existence of a transcendental region of human faculty, anthropologists appear to be unconcerned. The only English exception known to me is Mr. Tylor, and his great work, "Primitive Culture," was written thirty years ago, before the modern psychological studies of Professor William James, Dr. Romaine Newbold, M. Richet, Dr. Janet, Professor Sidgwick, Mr. Myers, Mr. Gurney, Dr. Parish, and many others had commenced. Anthropologists have gone on discussing the trances, and visions, and so-called "demoniacal possession" of savages, as if no new researches into similar facts in the psychology of civilised mankind existed; or, if they existed, threw any glimmer of light on the abnormal psychology of savages. I have, on the other hand, thought it desirable to sketch out a study of savage psychology in the light of recent psychological research. Thanks to this daring novelty, the book has been virtually taken as two books; anthropologists have criticised the second part, and one or two Psychical Researchers have criticised the first part; each school leaving one part severely alone. Such are the natural results of a too restricted specialism.
