Trust must also fall by the way side because I need to trust in someone else, and that idea is destroyed if selves aren't unified. It is also claimed that we cannot understand ourselves unless we are unified over time. This is so because when I think about and understand myself, I do so in reference to my past, future, and present. If the self were not unified it would only be able to make us of the snap-shot present and that wouldn't yield any understanding. This section discusses multiples.
Special concern is given to whether multiples are multiple simultaneously or through time.
Raddenn does not think there is any compelling reason to believe someone is multiple simultaneously given the observable behavior. We think of the two hemispheres of the brain as two people talking, but it isn't like that at all. Thus, there needn't be two centers of awareness for split brain patients to make the interesting mistakes they do. The subjective reports of thought insertion, depersonalization, derealization, etc are more difficult for Raddenn, but she dismisses them on the grounds that for me to tell you about my problem with thought insertion or my out of body experience, there must be one unity of consciousness that can report 'my' experience. For one thing, ownership of experience is grammatically guaranteed.
