Multiple Personalities. "Each alter is designed to do a job and only that job. It is endowed with characteristic traits which the Original Personality would have taken on, if it were in charge. The situation can be viewed as operating a doll factory, with only the outfits of clothes being produced. The doll, itself, is not present. The alters are the sets of clothes, but there is no doll inside any of them. Therefore, they cannot grow and change. They can only do what the ISH has programmed them to do."
