Obsessing ideas of such personal influence involve of course always a certain amount of emotional excitement and they may lead us to the unlimited field of disturbances in which the persecuting idea is surrounded by emotional attitudes. Analysis shows easily that the emotion is an essential factor and that it persists in the disease while the ideas to which it clings may change. Central is the emotion of fear; nearest to it that of worry, but any emotion may give color to the particular case. Again any number of methods may be applied and a few illustrations with quite different ways of treatment may indicate more fully the character of the trouble. There is no doctor in the city and none in the remotest village who may not find such cases in his near neighborhood. Of course slight degrees are easily hidden by the patient's own inhibition of external expression. If such suppression by the own will secures a real overcoming of the unjustified emotion, this is surely better than to begin any medical treatment. But as the suppression usually means simply lack of discharge and thus offers all the conditions for an unhealthy inner growth of the trouble, the neglect of such disturbances is most regrettable, and frankness of the patient must be encouraged. Such situation demands a careful observation of the whole case and a subtle adjustment of the treatment to the individual needs. It may perhaps be helpful at first simply to indicate the varieties of the more frequent disturbances of this kind by quoting from various letters. Each case belongs to a type which can easily be removed by psychotherapeutic influence, generally even by a skillfully directed autosuggestion. The writer is a young man. "I have always, as long as I can remember, been very nervous and sensitive. When about seven years of age, I was attacked by St. Vitus' Dance. Before that I cannot say whether I was particularly nervous or not. Afterward it was impressed upon me by the remarks of relatives that I was nervous, so that I soon took note of this condition myself. The manner in which this weakness has been especially troublesome is that it has caused me to be very shy. I shrank from new acquaintances and disliked being observed. Often in walking along on the street, I imagined myself closely noticed by the passerby and I always felt uncomfortable.
