And as the years passed and he was enabled to coordinate the results of the investigations carried on by the different committees, he gradually became convinced that over and beyond the self of which man is normally conscious there existed in every man a secondary self endowed with faculties transcending those of the normal wake-a-day self. To this he gave the name of the "subliminal self," and, in the words of Professor James, "endowed psychology with a new problem,--the exploration of the subliminal region being destined to figure thereafter in that branch of learning as Myers's problem." Not content with this, he gave himself, with all the earnestness that had originally drawn him into activity with Sidgwick, to the formulation of a cosmic philosophy based on the hypothesis of the subliminal self and its operations in that unseen world of whose existence he no longer doubted. Here he laid himself open to the charge of extravagance and transcendentalism, and undoubtedly exceeded the logical limit. But for all of that his labors--cut short by death six years ago, and only a few months after the death of his beloved master, Sidgwick--have been little short of epoch marking, and amply suffice to vindicate the existence of the once despised, and still by no means venerated, Society for Psychical Research. Sir William Crookes, Sir Oliver Lodge, and Mr. Frank Podmore are other members of the society who have granted the outside world informative glimpses of its workings and discoveries. Sir William Crookes, of course, is best known as a great chemist, discoverer of the element thallium, and inventor of numerous scientific instruments; while Sir Oliver Lodge's most striking work has been in electricity, and more particularly in the direction of improving wireless telegraphy. But both have long been actively interested in psychical research, and perhaps most of all in those phases of it bearing on the telepathic hypothesis, their great aim being to discover just what the technique of telepathic communication from mind to mind may be. Mr. Podmore, on the other hand, like Richard Hodgson, has chiefly concerned himself with psychical research from the detective, or critical, standpoint. He began his labors late in the '70's, associating himself with the Cambridge group, and has consistently maintained the attitude of a skeptical, though open minded, investigator. To-day, to a certain extent, he may be said to occupy the place so long filled by Henry Sidgwick as a sane, restraining influence on the less judicial members of the society, who would unhesitatingly brush aside all objections and embrace the spiritistic hypothesis with all its supernatural implications.[T]
