There is first of all an emotional instability, with a tendency to prolonged and freakish manifestations,--the well-known hysterics with laughing, crying, etc. Fundamental in the personality of the hysterics is this instability, this emotionality, which is however secondary to an egotistic, easily wounded nature, craving sympathy and respect and often unable legitimately to earn them. A group of symptoms that seem hard to explain are the so-called paralyses. These paralyses may affect almost any part, may come in a moment and go as suddenly, or last for years. They may concern arm, leg, face, hands, feet, speech, etc. They seem very severe, but are due to worry, to misdirected ideas and emotions and not at all to injury to the nervous system. They are manifestations of what the neurologists call "dissociations of the personality." That is, conflicts of emotions, ideas, and purposes of the type previously described have occurred, and a paralysis has resulted. These paralyses yield remarkably to any energizing influence like good fortune, the compelling personality of a physician or clergyman or healer (the miracle cure), or a serious danger. The latter is exemplified in the cases now and then reported of people who have not been out of bed for years, but are aroused by threat of some danger, like a fire, reach safety, and thereafter are well. Similar in type to the paralyses are losses of sensation in various parts of the body,--losses so complete that one may thrust a needle deep into the flesh without pain to the patient. In the days of witch-hunting the witch-hunters would test the women suspected with a pin, and if they found places where pain was not felt, considered they had proof of witchcraft or diabolic possession, so that many a hysteric was hanged or drowned. The history of man is full of psychopathic characters and happenings; insane men have changed the course of human events by their ideas and delusions, and on the other hand society has continually mistaken the insane and the nervously afflicted for criminals or wretches deserving severest punishment. Especially striking in hysteria are the curious changes in consciousness that take place. These range from what seem to be fainting spells to long trances lasting perhaps for months, in which animation is apparently suspended and the body seems on the brink of death. In olden days the Delphian oracles were people who had the power voluntarily of throwing themselves into these hysteric states and their vague statements were taken to be heaven-inspired. To-day, their descendants in hysteria are the crystal gazers, the mediums, the automatic writers that by a mixture of hysteria and faking deceive the simple and credulous.
