In the two examples I have cited, if my interpretation is correct, the amnesia was due to dissociation by conflict and hence the conservation, as is the rule in functional dissociation, and the reproduction by automatic writing. This principle of dissociation by conflict and of conservation of the dissociated remembrances is of great practical importance as we shall see in later lectures. It can be best studied experimentally with cases of multiple personality. In the case of Miss B. numerous examples of amnesia from conflict were observed. Owing to the precise organization of the consciousness into two distinct personalities it was possible to definitely determine beyond question the antagonistic ideas of one personality which voluntarily induced the conflict and, by the impulsive force of their emotion, caused the amnesia in the other personality.[38] The same phenomena were observed in the case of B. C. A. As memory for the forgotten experiences in these instances returned as soon as the conflict ceased, conservation of them necessarily persisted during the amnesia. Perhaps I may be permitted to digress here slightly to point out that this same (in principle) phenomenon may be effected experimentally by suggestion. The suggested idea which has the force of a volition or unexpressed wish, coming in conflict with the knowledge of previously familiar facts, inhibits or represses the reproduction in consciousness of this knowledge as memory. It is easy to prove, however, that this knowledge is conserved though it cannot be recalled. Thus, I give appropriate suggestions to B. C. A. in hypnosis that she shall be unable, when awake, to remember a certain unpleasant episode connected with a person named “August.” After being awakened she has complete amnesia, not only for the episode, but even for the name. The suppression of the memory of the episode carries with it by association the name of the person. In fact, the name itself has no meaning for her. When asked to give the names of the calendar months after mentioning “July” she hesitates, then gives “September” as the next. Even when the name “August” is mentioned to her it has no meaning and sounds like a word of a foreign language. The memory of the episode has become dormant so far as volitional recollection is concerned. It can, however, be _recalled as a coconscious process_ through automatic writing, as in the preceding experiment, and then the word in all its meanings and associations is also awakened in the coconsciousness.
