The status of the old-fashioned ghost story has, within the past ten years, perceptibly changed. Formerly, by the credulous generality of people, it was almost universally accepted without reason and without critical examination. It was looked upon as supernatural, and supernatural things were neither to be doubted nor reasoned about, and there the matter ended. On the other hand, the more learned and scientific, equally without reason or critical examination, utterly repudiated and scorned all alleged facts and occurrences relating to the subject. "We know what the laws of nature are," they said, "and alleged occurrences which go beyond or contravene these laws are upon their face illusions and frauds." And so, with them also, there the matter ended. In the meantime, while the irreclaimably superstitious and credulous on the one hand, and the unco-scientific and conservative on the other, equally without knowledge and equally without reason, have gone on believing and disbelieving, a large number of people--intelligent, inquiring, quick-witted, and reasonable, some scientific and some unscientific--have come to think seriously regarding unusual occurrences and phenomena, either witnessed or experienced by themselves or related by others, and whose reality they could not doubt, although their relations to ordinary conditions of life were mysterious and occult. In the investigation of these subjects some new and unfamiliar terms have come into more or less common use. We hear of mind-reading, telepathy, hypnotism, clairvoyance, and psychical research, some of which terms still stand for something mysterious, uncanny, perhaps even supernatural, but they have at least excited interest and inquiry. The subjects which they represent have even permeated general literature; the novelist has made use of this widespread interest in occult subjects and has introduced many of the strange and weird features which they present into his department of literature. Some have made use of this new material without knowledge or taste, merely to excite wonder and attract the vulgar, while others use it philosophically, with knowledge and discrimination, for the purpose of educating their readers in a new and important department of knowledge and thought. Amongst the more scientific, societies have been formed, reports have been read and published, so that in scientific and literary circles as well as among the unlearned the subject has become one of interest. The object of these papers will be briefly to tell in connection with my own observations, what is known and what is thought by others who have studied the subject carefully, and especially what has been done by the English Society for Psychical Research and kindred societies.
