perhaps Salinger is making some kinda play on society, like holden isn't the crazy one, but he's the one who's in therapy; the phoniness is everywhere...where are the evidence of all these personalities, if he is supposed to be schizophrenic? i don't see that at all. i think that one of the main points of the book is that holden is confused about growing up, not a raving maniac with a bunch of people running around in his brain.
