'It is very probable that Mr. Rolfe is, unknown to himself, a physical medium, and that when he was in the confined space of the cellar he turned it into a cabinet in which his magnetic powers could accumulate and be available for use.' (It is hard to believe that he who speaks like this about 'magnetic powers' once had at least an elementary knowledge of physics.) On page 170 we read, concerning another poltergeist, that '... a clergyman, with some knowledge of occult matters, has succeeded by sympathetic reasoning and prayer in obtaining a promise from the entity that it will plague the household no more.' [Footnote 19: A poltergeist is a spirit that throws things about; its appearance is generally associated with the presence of some young person, whose tricks may be detected to the discredit of the ghostly cause. If trickery is not detected the poltergeist is the manifestation of an evil spirit.] Poor Mr. Rolfe has had a narrow escape of being mixed up with an 'entity' who, or which, might have led him to the stake in a thorough-going spiritualist age. This relation between spiritualism and witchcraft is not a fantasy of my unconscious; listen to this from another believer:-- 'The dangers of the spiritual world are greater because, bad as a man living on our plane may be, he cannot compare in that respect with a thoroughly wicked denizen of the fourth-dimensional space, whose power is all the greater because his very existence is almost universally denied. What little good was ever in him has been blotted out in the course, perhaps, of centuries; his cunning passes earthly comprehension; his experience of the ways and foibles of humanity is profound; his malignity is dreadful. To be fully under the influence of such an entity as this is to be at his mercy, and, as no such word exists in his vocabulary, the end is a foregone conclusion, unless another force of a contrary character and at least as powerful is directed against him.'[20] [Footnote 20: _Problems of the Borderland_, p. 49, by J. Herbert Slater. Wm. Rider & Sons, 1915.] It is indeed fortunate that the existence of these entities is almost universally denied. Hangings and burnings would be soon in fashion again if any large proportion of us were influenced by such a horrible complex.
