The entrance to the Park was black with human beings, some massed in groups, some running anxiously back and forth like ants when their hill has been crushed. There were blanched faces and trembling hands. The wildest rumors were in circulation and every bearer of tidings was immediately surrounded.[59]

Not only here but when the crowd trekked back, and in the subsequent scenes which were witnessed in supply stations and shelters, the association which Sidis draws between calamity and hyper-suggestibility in the body politic was abundantly endorsed.

We must now endeavor to understand the phenomena of emotion which accompany a great catastrophe. This is not the less difficult because the term emotion is not given consistent use even by psychologists. One interprets it as merely the affective side of the instinctive process—those “modes of affective experience,” such as “anger, fear, curiosity,” which accompany the excitement of “the principal powerful instincts.”[60] Another sees it as also an impulsive, not merely a receptive state. It is “the way the body feels when it is prepared for a certain reaction,” and includes “an impulse toward the particular reaction.”[61]

It will be accurate enough for our purpose to think of the emotions as complicated states of feeling more or less allied to one another and to the human will.[62] Among them are jealousy and envy—“discomfort at seeing others approved and at being out-done by them.”[63] This appeared repeatedly in the administration of relief and should be included in disaster psychology. Again greed[64]—more strictly a social instinct than an emotion—was common. How common will receive further exemplification in a [later chapter].

Fear has already been referred to. Anger, shame, resentment while evident, were of less significance. Gratitude was early shown and there were many formal expressions of it. Later on, it seemed to be replaced by a feeling that as sufferers they, the victims, were only receiving their due in whatever aid was obtained.

Of special interest is the rôle of the tender emotions, kindliness, sympathy and sorrow, as well as the reactions which may be expected when these occur in unusual exaltation through the repetition of stimuli or otherwise. Whatever may be the nature of the process whereby the feelings of his fellows affect a man, that which chiefly concerns us here, is how these reactions differ when the stimulation is multiplex. Of this multiplex stimulation in collective psychology Graham Wallas has written:

The nervous exaltation so produced may be the effect of the rapid repetition of stimuli acting as repetition acts, for instance, when it produces seasickness or tickling.... If the exaltation is extreme conscious control of feeling and action is diminished.[65] Reaction is narrowed and men may behave, as they behave in dreams, less rationally and morally than they do if the whole of their nature is brought into play.[66]

What Wallas has said of the additional stimulation which the presence of a crowd induces may be given wider application, and is indeed a most illuminating thought, describing exactly the psycho-emotional reactions produced by the stimulation of terrifying scenes, such as were witnessed at Halifax.

A case in point was that of the nervous exaltation produced upon a young doctor who operated continuously for many hours in the removal of injured eyes. The emotional tension he went through is expressed in his words to a witness: “If relief doesn't come to me soon, I shall murder somebody.”

Another instance where conscious control of feeling and action was diminished was that of a soldier. He was so affected by what he passed through during the explosion and his two days' participation in relief work, that he quite unwittingly took a seat in a train departing for Montreal. Later in a hospital of that city after many mental wanderings he recovered his memory. Over and over again he had been picturing the dreadful scenes which he had experienced. This condition includes a hyperactivity of the imagination “characterized by oneirism [oneiric delirium] reproducing most often the tragic or terrible scenes which immediately preceded the hypogenic shock.”[67]
