Masterson is also a very famous psychoanalyst who is one of the world's best authorities on borderline personality disorder. One of the reasons he is so optimistic, is also the rub. The thought is that all personality disorders do not have these personalities imposed upon their real selves but that these personalities have become part and parcel OF the real self. It is integral, organic to the individual if you will. However, with psychoanalysis and possibly psychoanalytic psychotherapy there is the distinct possiblity that one can rebuild one's personality. I know it sounds awful doesn't it? But that is one true road to go on. The man knows his stuff.
