will in many cases give proof of knowledge outside the range of the primary consciousness; it may show traces of keener sensibilities, and even of new faculties. Again, in some cases, it will act in opposition to its host. It will repudiate their common identity; and will take pains to thwart the schemes made by the other self. This opposition of the primary and secondary consciousness occurs even in the simpler forms of automatism; planchette will frequently write coarse or blasphemous expressions which are repugnant to the upper self. Extreme instances of opposition will be found in certain pathologic cases, especially in the mutual relations of the several "personalities" incarnated in the body of Miss Beauchamp. Strange and almost incredible as are some of the things recorded, they seem to represent no more than an exaggerated form of the struggle between opposing tendencies which is constantly taking place in human life—a struggle which forms indeed the very basis of moral evolution.
Thus, when the secondary personality assumes the name of a deceased friend of those present, mimics his attitude, his gestures and ways of speaking, and the external features of his personality,
view taken by Dr. Morton Prince himself, that "Sally" is to be regarded as merely a lay-product of the patient's mental disintegration, a split-off group of states of consciousness. In Mr. M'Dougall's view, if the facts are correctly recorded, the personality named "Sally" must be regarded as "a psychic being or entity distinct from that of the normal Miss B": in short, if I understand him rightly, an invading or obsessing spirit.
