Existential isolation, a third given, refers to the unbridgeable gap between self and others, a gap that exists even in the presence of deeply gratifying interpersonal relationships. One is isolated not only from other beings but, to the extent that one constitutes one's world, from world as well. Such isolation is to be distinguished from two other types of isolation: interpersonal and intrapersonal isolation. One experiences interpersonal isolation, or loneliness, if one lacks the social skills or personality style that permit intimate social interactions. Intrapersonal isolation occurs when parts of the self are split off, as when one splits off emotion from the memory of an event. The most extreme, and dramatic, form of splitting, the multiple personality, is relatively rare {though growing more widely recognized}; when it does occur, the therapist may be faced {...} with the bewildering dilemma of which personality to cherish.
