This same lady happened to be in Petrograd during that sanguinary Revolution of the 22nd of January, and saw a street cleared by the volleys of soldiers. All around her people were dropping down dead or wounded, but she retained her calmness and self-possession, and caught sight of a door which gave her escape into another street. These terrible moments agitated her neither at the time nor later on. She was quite well afterwards, indeed felt better than usual.
Essentially similar reactions can quite often be observed. Hence it follows that the intensity of the trauma is of small pathogenic importance; the peculiar circumstances determine its pathogenic effect. Here, then, we have the key which enables us to unlock at least one of the anterooms to an understanding of predisposition. We must now ask what were the unusual circumstances in this carriage scene? The terror and apprehension began as soon as the lady heard the trampling horses. For a moment she thought this portended some terrible fate, her death, or something equally frightful; the next, she lost all sense of what she was doing.
This powerful impression was evidently connected in some way with the horses. The predisposition of the patient to react in such an exaggerated fashion to a not very remarkable incident, might result from the fact that horses had some special significance for her. It might be suspected that she had experienced some dangerous accident with them; this actually turned out to be the case. When a child of about seven years old she was out for a drive with the coachman; the horses shied and galloped at full speed towards a steep river-bank. The coachman jumped down, and shouted to her to do the same, but in her extreme terror she could scarcely bring herself to obey. She did, however, just manage to jump out in the nick of time, whilst the horses and carriage were dashed to pieces below. No proof is needed that such an experience must leave a lasting impression behind it. But it does not offer any explanation for such an exaggerated reaction to an inadequate stimulus. So far we only know that this later symptom had its prologue in childhood, but its pathological aspect remains obscure. To penetrate into
