That bubonic plague, typhus, fever, influenza, smallpox, and other serious diseases alter the sensations, emotions, and feelings of their victims need not be demonstrated. The general characteristic of the change induced by all these diseases is the pain, fear of death, delirium, and sense of weakness experienced by the victim. Apart from this common trait, each of the main epidemics discloses its own pattern of transformation of the victim’s sensations, feelings, and emotions. For our purposes it is unnecessary to characterize the specific changes produced by each of these diseases. It suffices to say that all the important pestilences profoundly transform the emotional and affective life of the patient. This transformation is due nor only to the biological forces of the sickness itself but also to the profound change in the social relationships of the victim. He suddenly finds himself isolated from almost all his fellow men, often even the members of his family. His condition plunges him into a sort of social vacuum. Hundreds of persons with whom he was linked by the ties of friendship and attachment, business, and common interests now try to avoid him. The victim is in the position of a spider whose web has been torn asunder. The former subject–or active participant in social life–is turned into a helpless object, avoided, forsaken, and repellent. He ceases to form a part of society. Socially he is already dead though he is still alive biologically.
Regardless of the biological factors, this abrupt psychosocial lonesomeness, this social death, is alone sufficient to create the profoundest change in the victim’s affective and emotional life. Even gradual psychosocial isolation alters the whole mental life of persons so profoundly that often it drives people to commit suicide. As a matter of fact, psychosocial isolation is the primary cause of so-called “egotistic” suicide. Vastly more profound is the change created by the psychosocial isolation due to pestilence. It comes abruptly; it isolates the victim suddenly. It effects a thoroughgoing revolution in the mental life of the victim.
Pestilence affects also the emotional life of all those who are in contact with the sick. Their emotional tone is also profoundly disturbed. Anxiety, sorrow, and fear, sympathy for the sick and egoistic concern for their own safety, hope and despair, mounting depression alternating with outursts of macabre exhilaration, irritability, and fatalistic resignation, emotional excitation and dullness, a reckless “devil may care” attitude and intense religiosity–these and similar waves of emotion sweep over the society ravaged by a pestilence. As in famine, its emotional life becomes unstable, jumpy, and uneven, subject to contrasting moods and violent changes. This instability and these contrasting emotional changes are probably the most important characteristics of such a society from the sociological standpoint.
