Back of the neurosis the motive of which is to worry the old father, to irritate him and force him to pay attention to the unsuccessful son, stands hidden his passionate love of the father, though he writes him scolding letters, 20 sheets long, and threatens to shoot him, should he dare cut down his rightful inheritance. A certain memory trace leads to various childhood fancies resembling the affairs with boys already mentioned. Finally he brings forth a reminiscence placing his father in an unpleasant light. The father was also a drinker.... It seems as if he had tried to forget that fact. His fancies of murder are directed against the father. That becomes clearer all the time. He turns ill and addicted to veronal so as to commit no crime. He feels his father slights and neglects him. They quarrel all the time on account of his dissipations. The father threatens he will be no longer responsible for his debts. The son must give up his expensive habits of living. Then the war broke out. He was among the first volunteers to answer the call, distinguished himself several times with his conduct, and finally met his death in an engagement. I have already pointed out elsewhere in this work the latent homosexuality of drinkers. In the light of these new considerations, the well-known jealousy of drinkers reveals an additional feature. The intoxication is to a certain extent a periodic artificial paranoia during which the ideas of persecution come to the foreground. This is very clearly to be seen in many cases. In that particular respect the alcohol addict is hardly different from the paranoiac. Both believe in the objectivity of their insane notions. The following two case histories of drinkers’ jealousy will conclude this lengthy list of illustrative cases: 80. Mr. N. V., Captain, married at the age of 34 and has been married two years. His marriage was unhappy from the very first day. Previous to that he had had intercourse only with _puellæ publicæ_ and with them was always potent. With his wife he is impotent. He is very unhappy over it and consoles himself with street women. He began to drink and beats his wife while intoxicated. He scolds her, calls her a whore and accuses her of intimacy with all the officers. Although he had been drinking formerly, he did so with moderation, but now he is a confirmed _potator_, spends his time in dram shops and while intoxicated becomes very friendly with the waiters and other underlings, kissing them and toasting their comradeship. He is firmly convinced that his wife is unfaithful to him and even suspects his boy whom he beats mercilessly when under the influence of drink. The woman left her husband and fled to her parents.
