To the first group we add those cases in which the patient has not reacted to psychic traumas because the nature of the trauma precluded a reaction as in the case of an irremediable loss of a beloved person or because social relations made the reaction impossible, or because it concerned things which the patient wished to forget and which he therefore intentionally inhibited and repressed from his conscious memory. It is just those painful things which in the hypnotic state are found to be the basis of hysterical phenomena (hysterical delirium of saints, nuns, abstinent women, and well-bred children). The second series of determinants is not conditioned by the content of the memories but by the psychic states with which the corresponding experiences in the patient have united. As a cause of hysterical symptoms one really finds in hypnosis presentations which are insignificant in themselves but which owe their preservation to the fact that they originated during a severe paralyzing affect like fright or directly in abnormal psychic conditions, as in the semi-hypnotic dreamy states of reveries, in autohypnosis and similar states. Here it is the nature of these conditions which make a reaction to the incident impossible. To be sure both determinants may unite, and as a matter of fact they often do. This is the case when a trauma in itself effective occurs in a state of a powerful paralyzing affect or in a transformed consciousness. But due to the psychic trauma it may also happen that in many persons one of these abnormal states occurs which in turn makes a reaction impossible. What is common to both groups of determinants is the fact that those psychic traumas which are not rectified by reaction are also prevented from adjustment by associative elaboration. In the first group it is due to the resolution of the patient who wishes to forget the painful experiences and in this way, if possible, to exclude them from association, and in the second group the associative elaboration does not succeed because there is no productive associative relationship between the normal and pathological state of consciousness in which these presentations originated. We shall soon have occasion to discuss more fully these relationships. Hence we can say, _that the reason why the pathogenically formed presentations retain their freshness and affective force is because they are not subject to the normal waste through ab-reaction and reproduction in conditions of uninhibited association_.
