In some of the higher planes of imbecility a considerable degree of intellectual brightness, or even talent, is often observed, and every variety of mental and moral perversion or simple reckless brutality. Training often does a great deal to bring many of these unfortunate creatures within the bounds of good behavior, but their care oftener falls within {140} the province of the medical superintendent in an asylum or the teacher than to the physician in general practice. They are easily led astray by others, and commit all sorts of motiveless crimes or with a trivial or disproportionate motive, and with blind disregard of consequences or inability to comprehend them. In the gallery, at Washington, of photographs of counterfeiters and of passers of counterfeit money, the faces of the latter show conclusively that they belong to the intellectually weak-minded or imbecile class. Their own amusement, gratification, or impulse is so far the basis of their conduct that only a minority are harmless if not more or less constantly watched. Fortunately, a great portion—unfortunately, not all—of the idiots are sterile, but many of the mentally and morally weak-minded, with striking congenital defects which no training can fully remedy, propagate their species indefinitely for the benefit of our prisons and asylums. Intellectual idiocy and marked intellectual imbecility are so common as to constitute 1 in 650 of our population. Less noticeable intellectual imbecility is quite frequent in the large class of troublesome and perverse children and youth of both sexes, commonly called weak-minded. Moral imbecility, which cannot be corrected by education, is less common. Moral idiocy is rare. It consists in such an absence of the moral sense that it cannot be aroused. It is sometimes associated with sufficient intellectual powers to make deliberate action and premeditation quite possible. Such persons are monstrosities, who, for the safety of the community, must be kept shut up for life like wild beasts. The fact should be remembered, from a medico-legal point of view, that the defective in mind are quite liable to short attacks of simple mania and mental depression and to epilepsy, both of the obvious type and of the obscure or masked form, so that their degrees of responsibility, or rather of irresponsibility, vary from time to time. As a rule, a good physical organization and a general condition denoting healthy circulation and nutrition mark the better brains, and constitute important elements in forming a prognosis in regard to the possibility of educating imbecile and feeble-minded children up to the point of reasonably good behavior and ability to at least partly take care of themselves. The simpler their lives and the more purely routine or imitative their work, the less their defect is noticed. Many can wheel a barrow as well as any one.
