upper hand. She groups her own mental products around the personality of the hypnotiser, that is, of the grandfather, now degraded to a mere image. In this way we are enabled to understand the dualism in the character of the grandfather. The grandfather I. who speaks directly to those present, is a totally different person and a mere spectator of his double, grandfather II., who appears as Ivenes’ teacher. Grandfather I. maintains energetically that both are one and the same person, and that I. has all the knowledge which II. possesses, and is only prevented from giving information by the difficulties of speech. (The dissociation was of course not realized by the patient, who took both to be one person.) Grandfather I., if closely examined, however, is not altogether wrong, judging from one fact which seems to make for the identity of I. and II., viz. that they are never both present together. When I. speaks automatically II. is not present; Ivenes remarks on his absence. Similarly, during the ecstasy, when she is with II., she cannot say where I. is, or she may learn only on returning from an imaginary journey that meanwhile I. has been guarding her body. Conversely I. never says that he is going on a journey with Ivenes and never explains anything to her. This behaviour should be noted, for, if I. is really separate from II., there seems no reason why he should not speak automatically at the same time that II. appears, and also [no reason why he should not] be present with II. in the ecstasy. Although this might have been supposed possible, as a matter of fact it was never observed. How is this dilemma to be resolved? At all events there exists an identity of I. and II., but it does not lie in the region of the personality under discussion; it lies in the basis common to both; that is, in the personality of the patient which in deepest essence is one and indivisible. Here we come across the characteristic of all hysterical dissociations of consciousness. They are disturbances which only belong to the superficial, and none reaches so deep as to attack the strong-knit foundation of the ego-complex.
In many such cases we find the bridge which, although often well-concealed, spans the apparently impassable abyss.
