Other morbid symptoms, such as obsessions and pathological impulses, have a certain importance as regards sexual appetite and love. Love or rejection, as well as other sexual images, may become the objects of obsessions, and then cause the subjects much torment, but without harming their surroundings; for the obsessed generally remain passive. Pathological impulse to actions may, on the contrary, become dangerous and lead to violation, whether combined with perversion or not. (12). We have seen that _senile paradoxy_ often shows itself, as a symptom of senile dementia, by a sexual appetite for children. This is the initial symptom of the complaint, and may lead to the commission of assault. The holy indignation of the public, and often of ignorant judges, against these depraved old men often result in the public contempt or even the imprisonment of poor patients who have hitherto led a blameless life, and who have simply become victims of senile degeneration of the arteries of the brain. (13). I will mention another case which I have observed, which shows how complex hereditary cerebral pathology may become, and lead in turn to crime, madness and sexual perversion; giving rise to the most tragic scenes of human life, and to the degeneration of families. A very charming and intelligent, but deceitful man, an amoral person whose heredity was strongly tainted with mental disease, had strong sexual instincts partly inverted. He was attracted rather more by men than by women, but committed excesses with both sexes. He married a virtuous and intelligent midwife. At long intervals he had three attacks of acute mania, but was cured after each attack and procreated two boys and a girl. When he was sane he spent his time in deceitful occupations and speculation and never worked honestly to earn his living. He behaved well toward his wife, but this did not prevent him committing pederasty with men. He was often convicted for pederasty and swindling, and I treated him several times in an asylum. His poor wife complained bitterly, but found consolation in her husband's apparent love, but especially in the careful education of her children. But when the children grew up, her illusions disappeared one after another. The daughter became feeble-minded, and one of the sons became a bad character. The mother consoled herself with the second son who appeared honest and hard-working. The father was then in an asylum, his relapses having led the tribunal to institute an inquiry into his mental condition. One day the mother came to me in despair and showed me a letter written by the son of the father, which she had opened; the contents were as follows: "Miserable father, when you receive this letter I shall be no longer in this world; but before dying I wish to curse you. You have been the disgrace of the family. You have caused misery to our mother and her
