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. The authors have attempted to condense: (a) all the experimental and evaluative methods by which the research has been done and by which its adequacy must be judged; (b) all of the results obtained--grouped, classified, and analyzed so as to enable them to be assayed critically from the point of view of all possible alternatives; (c) a thorough digest of the criticisms, both constructive and otherwise; and (d) all of these as they bear upon the clarified question about which the research is concerned, with as much of an answer to that question as the assembled material permits. In addition--and assuming that ESP occurs--there is given here a summary of all the established and partially established relations of ESP to better-known processes, indicating the relations between ESP and the individual, the relation of ESP to the conditions under which it is tested, indications of its place in the physical and mental worlds, as far as these are shown by the results. And last, for the student, the experimenter, and the forward-looking follower of these experiments, there is a sketch of the outstanding problems that still remain unsolved, the methods under contemplation by which they may possibly be solved, and the further needs and prospects which confront investigators now dealing with ESP and associated problems".
