The connection is often so clear that it is perfectly manifest how the causal event produced just this and no other phenomenon. It is quite clearly determined by the cause. Thus let us take the most banal example; if a painful affect originates while eating but is repressed, it may produce nausea and vomiting and continue for months as a hysterical symptom. A girl was anxiously distressed while watching at a sick bed. She fell into a dreamy state and experienced a frightful hallucination, and at the same time her right arm hanging over the back of a chair became numb. This resulted in a paralysis, contracture, and anesthesia of that arm. She wanted to pray but could find no words, but finally succeeded in uttering an English prayer for children. Later, on developing a very grave and most complicated hysteria, she spoke, wrote, and understood only English, whereas her native tongue was incomprehensible to her for a year and a half. A very sick child finally falls asleep. The mother exerts all her will power to make no noise to awaken it, but just because she resolved to do so she emits a clicking sound with her tongue (“hysterical counter-will”). This was later repeated on another occasion when she wished to be absolutely quiet, developing into a tic which in the form of tongue clicking accompanied every excitement for years. A very intelligent man was present while his brother was anesthetized and his ankylosed hip stretched. At the moment when the joint yielded and crackled he perceived severe pain in his own hip which continued for almost a year. In other cases the connection is not so simple, there being only as it were a symbolic relation between the cause and the pathological phenomenon, just as in the normal dream. Thus psychic pain may result in neuralgia, or the affect of moral disgust may cause vomiting. We have studied patients who were wont to make the most prolific use of such symbolization. In still other cases such a determination is at first sight incomprehensible, yet to this group belong the typical hysterical symptoms such as hemianesthesia, contraction of visual field, epileptiform convulsions and many others. The explanation of our views on this group we have to reserve for the more detailed discussion of the subject.
