This is not the place to enter into an explanation of dissociated personality, but I may point out, in anticipation of a deeper discussion of the subject, that, in accordance with these two principles, in such conditions we sometimes find that disposition and other complexes conserved in the unconscious come to the surface and displace or substitute themselves for the other complexes which dominate a personality. A complex or system of complexes that is only a mood or a “side of the character” of a normal individual, may in conditions of dissociation become the main complex and chief characteristic of the new personality. In Miss B., for instance, the personality known as BI was made up almost entirely of the religious and ethical ideas with corresponding instincts which formed one side of the original self. In the personality known as Sally we had for the most part the chronological and mood complexes of youth representing the enjoyment of youthful pleasures and sports, the freedom from conventionalities and artificial restraints generally imposed by duties and responsibilities; she was a resurrection of child life. In BIV the complex represented the ambitions and activities of practical life. In Miss B., as a whole, normal, without disintegration, it was easy to recognize all three dispositions as sides of her character, though each was kept ordinarily within proper bounds by the conflicting influence of the others. It was only necessary to put her in an environment which encouraged one or the other side, to associate her with people who strongly suggested one or the other of her own characteristics, whether religious, social, pleasure-loving, or intellectual, to see the characteristics of BI, Sally, or BIV stand out in relief as the predominant personality. Then we had the alternating play of these different sides of her character. Likewise in B. C. A. In each of the personalities, B and A, similar disposition complexes could be recognized each corresponding to a side of the character of the original personality C. In A were represented the complexes formed by ideas of duty, responsibility, and moral scruples; in B were represented the complexes formed by the longing for fun and the amusements which life offered. When the cleavage of personality took place it was between these two complexes, just as it was in Miss B. between the several complexes above described. This is well brought out in the respective autobiographies of B[150] and Sally[151] in these two cases. In many cases of hysteria in which dissociation of personality can be recognized the same phenomenon is often manifest. A careful study will reveal it also, I believe, in other cases of multiple personality, although, of course, as we have seen, the dissociation may be along other lines; that is, between other complexes than those of disposition.
