MORAL INSANITY (Insanity of Action, Affective Insanity, l'Insanite morale, Moralisches Irresein, Folie raisonnante, Folie lucide, Manie sans délire of Pinel), the general moral mania of Ray, is distinguished by that writer from partial moral mania (instinctive mania, manie raisonnante of Pinel, la folie impulsive, impulsive insanity, emotional insanity, impulsives Irresein), which includes suicidal insanity, homicidal insanity, dipsomania, pyromania, kleptomania, erotomania, nymphomania, satyriasis (aidoiomania), animal impulse, perverted sexual instinct (conträre Sexualempfindung, la sensation sexuelle contraire), and topophobia, if that disease be classed among the insanities. Moral insanity is seldom seen in the insane asylum until the disease has passed over into pronounced mental enfeeblement or delusional insanity. Purely moral insanity—“an uncontrollable violence of the emotions and instincts”—is probably as rare as purely intellectual insanity. Moral insanity is attended with some mental impairment, just as moral perversion is part of intellectual insanity. Indeed, I have heard patients complain as much of the degradation of character in their insanity as of any symptoms referable directly to the intellect. The term is not a fortunate one, but, like the expression moral treatment of the insane, it is in quite general use. It is recognized by all the authorities on mental disease, whatever may be their opinions as to the limitations of responsibility in it. It is especially to it that we can apply the words of the Autocrat of the Breakfast-Table, that the worst forms of insanity are those to which the asylum shuts its doors. It is marked by moral perversion, change of character and action, and so little intellectual impairment as to be easily overlooked by one not familiar with morbid mental phenomena. Mild simple mania ending in recovery has been described as moral insanity even by Pinel and Pritchard, and is so miscalled rather generally at the present day. Moral deterioration is observed after fevers or physiological periods of life, following slight and moderate cerebral hemorrhages or injuries to the back and head, affecting the brain, mental strain, etc., which, in persons of the neuro-psychopathic constitution, now and then end in permanent change of character. A similar but curable mental state is the frequent beginning of more pronounced insanity, and often remains the sole evidence of unsoundness of mind even after the patient is thought well enough to be discharged from the asylum. Although moral insanity is probably a common cause of young persons of both sexes being led into lives of licentiousness, wickedness, and crime, it is to be carefully differentiated from deliberate yielding to temptation and following lives of vice until a strong enough motive is offered for doing better or a punishment is made sufficient to be deterrent.
