Excerpt

The phenomena called "thought-reading" and "lucidity," and later known as "telepathy" and "clairvoyance," have in recent decades come to occupy a place in the scientific literature and laboratory under the name of extra-sensory perception (ESP). Although a great deal of work has been done in the field during this period and much has been written in controversy over the subject, there has been hitherto no attempt to present a thorough survey of the whole attack on the problem; scientists as well as lay readers have lacked an opportunity to examine the evidence as a whole.

This book is intended to afford just such a complete review of the recent research in extra-sensory perception, in the light of all of the criticisms that it has drawn. It is the purpose of the authors to include in this survey everything that is of importance to know in deciding whether ESP occurs, and what it is like if it does occur. It is their hope that the presentation will be clear enough to permit a view of the work in proper perspective, and yet technical enough to answer all the relevant questions as far as they have been answered by the results of experiments. How far this intention, this purpose, and this hope have been achieved is, of course, another matter; the best efforts of the many collaborators who have taken an active part in the preparation of this volume may not have been adequate to the size of the undertaking.

However, it seems best to submit now a summary of what has been achieved so far, even though it may mean that the accumulation of items for revision will have to begin before the ink is dry on this paper. The reason for this action is the evidence from many quarters of the urgent need for a monograph of this character.

First, interest in the subject of ESP has found its way into the psychology classroom and laboratory. Tests for extra- sensory perception have been introduced in many courses in . . .
