I trust that what I have written will act as an incentive to some of my readers to try experiments in this branch of psychical research.[2] It is not enough that a few individuals by patient inquiry and experiment should have been convinced of the reality of telepathy. What is wanted is that scientific men generally, by the record of an overwhelming number of experiments under the strictest test conditions, should be convinced of its truth. Once let them be so, then public conviction will in due time follow. Meanwhile I feel bound to state that, in spite of initial improbability, the experiences which I myself have had, as partly narrated in this book, especially those briefly summarized in Part I, have convinced me that the telepathic faculty does exist, and that its detection is a genuine extension of scientific knowledge; though much more will have to be done before the bare fact receives its explanation and is permanently incorporated in a coherent system of Science. [Footnote 2: Information relating to cases of genuine telepathy may be sent to the Secretary of the Society for Psychical Research, 20 Hanover Square, London, who will be pleased to investigate them.] PRINTED BY MORRISON AND GIBB LTD., EDINBURGH ---------------------------------------------------------------------- Transcriber's Note: Punctuation errors have been corrected without note.
