A lady, aged fifty-nine years, suffered from kynophobia. When about the age of twenty-nine years she was bitten by a dog; since then she was afraid of hydrophobia. She kept on reading in the papers about cases of hydrophobia until the fear became developed to an extraordinary degree and became fixed and uncontrollable. According to the principles of evolution of psychopathic states, the fear kept on extending. The fear psychosis included all objects that might possibly carry the germ of hydrophobia. The neurosis became a mysophobia.

As in all other cases of psychopathic states the psychosis was traced to the fear instinct, the germ of which was laid in the patient’s early history. The patient was a timid child, and was afraid of strange animals. In the village where she lived there were a few cases of hydrophobia which impressed her when a child. This germ was in later life developed by thirty years’ cultivation.

Psychopathic or neurotic symptom complexes I observed in children whose early training was favorable to the awakening and development of the fear instinct. In children affected with fear of animals I traced the fear psychosis to the parents who were afraid of animals, on account of actual traumas in their life history, the child being influenced by imitation, by suggestion, often subconscious, by the behavior of the parents in the presence of animals. Such children are predisposed to recurrent psychopathic states.

In all such cases the etiology is easy to find, if the patient is carefully examined. In many cases the fear instinct with its symptom complex is associated with external objects, giving rise to the so-called phobias. Instead, however, of being associated with external objects, the fear instinct is frequently associated with somatic functions (pathophobia), or with mental activities (phrenophobia).

Man, aged forty-seven years; actor; family neurotic. Patient suffered from anorexia, indigestion, choking, vomiting, gagging, eructation, gastralgia, and occasional pains in the limbs. He led a rather gay and irregular life up to the age of thirty-two years, when he had syphilis, for which he was under treatment for two years. This scared him because he had the opportunity to see the consequences of syphilis in many of his friends. He had been under continual fear of the possibility of development of parasyphilitic diseases.

Seven years ago, at the age of forty years, he had to watch at the bedside of an intimate friend, who had been suffering from severe gastric crises of tabes dorsalis. After one specially exhausting night of vigil, worry and fear, he went to bed for a short nap and woke up with the idea of general paresis and intense fear. From that time he began to suffer from symptoms of tabes with fear of general paresis.

The patient had been an imaginative child; he had his fear instinct cultivated from early childhood by stories of frights, scares, and horrible accidents. When ten years old, his grandfather gave Faust to him to read. Since then the patient was troubled with the fear of selling his soul to Satan. The patient was religious in his childhood, prayed much, and was possessed by the fear of committing sins. “It has now all come back,” he complained. A great number of fears could be traced to his early childhood. The somatic symptoms were the manifestations of association of experiences of parasyphilitic diseases, based on the pathological state of the fear instinct, a case of pathophobia, a somatopsychosis.

A few hypnoidal treatments effected a cure. The patient returned to his occupation, free from any distressing symptoms.

H. M. aged twenty-seven years, male, Canadian. Family history good; looked pale, anemic, and frail; very intelligent, sensitive, restless, and had a tendency to worry. About a year ago, he began to feel depressed, to worry about his health; thought he suffered from tuberculosis. His physician assured him that nothing was the matter, but he had an uncontrollable fear of consumption; and the idea kept on recurring. Up to the age of nineteen years he was perfectly well. He was then laid up with a sore knee for a few weeks. He had time enough to brood over the knee, and read some literature on the subject. He thought it was tuberculosis and worried much. The knee, however, got well, and gradually he forgot all about it, although the idea of tuberculosis often made him feel uncomfortable, and the idea of “water in the knee” used to flash through his mind, to pass away the next moment.

A year ago, however, he happened to lose his work, became despondent, began to worry and to brood over his financial troubles, slept restlessly, suffered from anorexia, and began to lose flesh. The idea of the knee and the fear of tuberculosis got possession of him. He could not rid himself of the idea of tuberculosis. If in the clinic the physician assured him that he was all right, he felt better for a couple of hours; but often it did not last even as long as that. The least pain, cough, heart beat, a feeling of chill or heat, and the like, brought the idea and fear of tuberculosis back to his mind with renewed energy. He was obsessed by the fear of tuberculosis and felt he was doomed to certain death, a psychosomatic pathophobia.
