We must agree with the French psychologist, Ribot, when he comes to the conclusion that “every lowering of vitality, whether permanent or temporary, predisposes to fear; the physiological conditions which engender or accompany it, are all ready; _in a weakened organism fear is always in a nascent condition_.” The fear instinct becomes morbid when the individual has to draw on his reserve energy, and finds he is unable to do it. The cure consists in the release of the reserve energy which has become inaccessible. This can be done by various methods, but the best is the method of induction of the hypnoidal state under the control of a competent psychopathologist. The whole process consists in the restitution of the levels of dynamic energy and the building up of the patient’s active personality. From our point of view, fear is not necessarily due to pain previously experienced, it may be purely instinctive. The fear instinct may be aroused _directly_, such for instance is the fear of young children who have never before experienced a fall. In fact we claim that the fear instinct and the restlessness which expresses it antedate and precede pain. The fear of pain is but one of the forms under which the fear instinct is manifested. The fear instinct appears long before pain and pleasure come into existence. This holds true not only of the lower animal life, but also of the vague fear found in many a case of neurasthenia and functional neurosis and psychosis. Ribot also calls attention to pantophobia. “This is a state in which the patient fears everything, where anxiety instead of being riveted on one object, floats as a dream, and only becomes fixed for an instant at a time, passing from one object to another, as circumstances may determine.” It is probably best to classify fears as _antecedent_ and _subsequent_ to experience, or fears as _undifferentiated_ and _differentiated_. When the dynamic energy is used up in the course of life adaptations, and reserve energy is drawn upon, there may be danger that the energy may be used up until the static energy is reached, and neuropathic conditions are manifested. These conditions are preceded by psychopathic disturbances. Associative life becomes disturbed, and emotional reactions become morbid. There is a degeneration or reversion to earlier and lower forms of mental activity, and to lower instinctive life. The primitive instincts, the impulse of self-preservation and the fear instinct, come to the foreground, giving rise to the various forms of psychopathic affections.
