Most of what has been said about the formation of complexes is a statement of commonplace facts, and I would not repeat it here were it not that, in certain abnormal conditions, disposition, subject, and other complexes, though loosely organized, often play an important part. This is not the place to enter into an explanation of dissociated personality, but in such conditions we sometimes find that disposition complexes, for instance, come to the surface and displace or substitute themselves for the other complexes which make up a personality. A complex which is only a mood or a "side of the character" of a normal individual may, in conditions of dissociation, become the main, perhaps sole, complex and chief characteristic of the new personality. In Miss Beauchamp, for instance, the personality known as BI was made up almost entirely of the religious and ethical ideas which formed one side of the original self. In the personality known as Sally we had for the most part the complex which represented the enjoyment of youthful pleasures and sports, the freedom from conventionalities and artificial restraints generally imposed by duties and responsibilities. In BIV the complex represented the ambitions and activities of practical life. In Miss Beauchamp 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 correcting 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. In fact, the total of our complexes, which, regarded as a whole and in view of their reaction to the environment, their behavior under the various conditions of social life, their aptitudes, feeling-tones, "habits," and faculties, we term character and personality, are in large part predetermined by the mental experiences of the past and the vestiges of memory which have been left as residual from these experiences. We are the offspring of our past.
