I may select a few typical theories, which all come from evidently otherwise normal and harmless people. I have before me a whole series of manuscripts from a druggist who is sure that his ego theory is “very near the truth.” It is in itself very simple and convincing. “The right and the left cerebral egos united with one sublime ego are in the body in a loose union in possession of an amœboid cell. During sleep they may separate. The sublime ego wanders through nerve paths to the bowels, and the bowel experiences are the dreams.” An experiment brought a definite proof of this. The druggist dyed some crackers deep blue with methylene blue, and later dreamed that a large train of blue food was passing by. As each carriage of the train corresponded to a granule of starch in the crackers, he was able to figure that the ego which saw those parts of the crackers was about one thousandth of an inch large. “The fact of seeing in dreams is due to vital force, the peculiar low speed to the high vibration force of living albuminoids emitted from every tendril of bioplasm and perceived by the eye of the ego-bion during its visit.” “Within the ego-bion is the ego itself, which is much simpler looking, about one hundredth of a micromillimeter.” I do not want to go into details of how these egos can be transmitted “by kiss or otherwise” from one generation to another, but I can say that as soon as the reader has grasped the fundamental thesis of the author, everything follows with perfect logic. The good man, who is doubtless a faithful druggist and whose mind is perfectly clear, has simply twisted some of the ideas which he has gathered from his ample reading and developed his pet theory.
