The foregoing two cases are representative of a group which unquestionably forms the most difficult part in the problem of caring for the insane criminals. Here we have a couple of individuals whose entire psychotic manifestations, if such they may be considered, consist of a most wild and vicious rebellion against imprisonment. They are individuals who cannot be kept under any prescribed mode of living, and when this is insisted upon, they react to it in an insane manner. Bonhoeffer justly termed them "wild men", for wild indeed they are when in one of their tantrums. The question arises, "Wherein lies the cause of this rebellion against discipline?" It certainly cannot be wholly attributed to the environment, for these individuals behave in a similar manner even when removed to the far more lenient régime of a hospital. We must seek an explanation for the behavior of these individuals in the individual himself, in his make-up. Looking at the life history of the two foregoing patients we find them both to be of the most depraved class of society. The one is a professional prostitute; the other subsisting upon the earnings of a prostitute. Their relation with man has always been characterized by a sort of vicious vindictiveness. Their high-strung emotional make-up brought them into serious conflict with those about them on many occasions before. Being finally taken hold of by the law and made to submit to a certain well-regulated mode of existence, their inherent characteristics assert themselves in a most decisive way and they react to the situation in the manner of a trapped tiger, stopping at no means to gain their point. The one commits a homicide during one of her outbreaks of passion; the other risks his life to obtain his purpose, by jumping out of a moving train with his hands shackled. Their life seems to be one long series of impulsions, fostered and sustained by the extreme lability of their emotions. Intellectually they show no defect. They are keen and alert to every opportunity which presents itself to them and are very shrewd in the execution of their criminal acts. Finding themselves under a régime which exacts from them a certain submission to rules, to regulations, they begin to misinterpret ordinary occurrences in their environment in a sort of delusional manner: They are persecuted by the warden because the latter insists upon making them behave themselves; the keepers are a bunch of anarchists, whose entire occupation seems to be to persecute them and down them. This for no other reason than because they are made to work and to behave themselves. J. J. M. tells me that he will not behave himself, that he is not here to please anyone but himself and recognizes no authority other than that of Christ. The other says she raised so much hell at the prison that they had to send her back to the hospital. The distinguishing feature of their psychotic manifestations is that they are provoked essentially by definite situations.
