This is a newer perspective on the makings of the "normal" mind which brings modern views of pluralism even to the inner workings of the mind. This is useful because if it becomes popular enough, it will make talking about multiplicity exceptionally easy, and it will head off the push for integration, since everyone is plural -- so to attempt to integrate would be counterproductive.
Multiples who do not want to enter therapy and be looked at like they have 3 heads and are crazy ought to seek out practitioners who believe in self-pluralism -- and in fact screen for therapists who have and admit to their own separate "parts" and have given them names, etc. If this becomes popular enough, perhaps it will become easier to seek out such persons when we feel we need a little professional help and guidance.
Self-pluralism bears more than a slight resemblence to 80s theories of ego-state families of selves used by some psychotherapists to assist juvenile delinquents. Because this type of theory tends to have an approach that they're "all you", it may not be ideal for all multiples.

Perhaps these ideas are not so "modern" though:
Other Lives, Other Selves by Roger J. Woolger, Ph.D. quotes (on p. 213) something by Gurdjieff in "Man Is a Plural Being" from 1922 [an excerpt from a book called Views from the Real World by E. P. Dutton, New York, 1975, p. 75] that states that there are "hundreds, thousands of little 'I's in every one of us. We are divided in ourselves but we cannot recognize the plurality of our being except by observation and study."
