In proportion as the neurotic attacks keep on recurring the formed pathological system is gaining in energy and in ease of manifestation. The psychopathic attacks with their symptoms emerge at an ever diminishing intensity of stimulation. The resistance of healthy normal associations is ever on the decrease until a point is reached when all power of resistance is lost. The conscious and subconscious groups which enter into the psychopathic system, forming the neurosis, get control over the patient’s life, and become an uncontrollable, psychopathic obsession. XV. _The Principle of Modification_ The patient attempts to control or alleviate his fear state by a totally different fear state. In the long run this is a losing game. For the general fear disposition becomes ultimately reinforced. Finally he may land in the mystic regions of love or of an Infinite Love in which he expects to find safety, protection, and salvation from the miseries of exaggerated self impulse and intensified fear instinct. Such a course, however, leads to a swamp in which the patient’s individuality becomes engulfed and obliterated. The end is mental suicide. These fundamental principles of neurosis-development should be kept in mind in the examination and study of psychopathic cases. The cases adduced in this volume will help one to understand the mechanism of the main factors and principles of neurosis. CHAPTER XVIII ILLUSTRATIONS, NEUROTIC HISTORIES The psychopathic character appears to be full of contradictions, “a house divided against itself.” Neurotics are like “the troubled ocean which never rests.” Some of my patients complain of fatigue, physical and especially intellectual, inability of concentration of attention, and yet they hint at being undeveloped, unappreciated geniuses. The patient may be said to suffer from a paradoxical state of “humble superiority.” A few of my cases may help one to form some faint idea of the intensity of the impulse of self-preservation and fear instinct which obsess the psychopathic sufferer.
