Between the criminal and the insane is a debatable line occupied by moral imbeciles, reasoning maniacs, &c. There are many insane persons in whom the principal deviation from the normal consists in disorder of the moral faculties. In most closer inspection generally reveals signs of degeneracy. The seeming immorality is the striking factor of the case and superficially the mind otherwise appears clear and rational by contrast. As Krafft-Ebing has shown in these cases, the most striking features are moral insensibility, lack of moral judgment and ethical ideas, the place of which is usurped by a narrow sense of loss or profit, logically apprehended only. Such persons may mechanically know the laws of morality, but if such laws enter their conscience these persons do not experience by any real appreciation, still less regard, for them. These laws to them are cold, lifeless statements. The morally defective know not how to draw from them motive for omission or commission. To this "moral colour-blindness" the whole moral and governmental order appears as a mere hindrance to egotistic ambition and feeling, which necessarily leads to negation of the rights of others and to violation of the same. These defective individuals are without interest for aught good or beautiful, albeit capable of a sentimentality which is shallow cant. Such persons are repellent by their lack of love for children or relatives, and of all social inclinations, and by cold-hearted indifference to the weal or woe of those nearest to them. They are without other than egotistic care for questions of social life or sensibility to either the respect or the scorn of others, without control of conscience and without sense or remorse for evil. Morality they do not understand. Law is nothing more than police regulation. The greatest crimes are regarded as mere transgressions of some arbitrary order. If such persons come in conflict with individuals, then, hatred, envy, and revenge take the place of coldness and negation, and their brutality and indifference to others know no bounds.
