I have traced the growth of cruelty obsession in children one would not suspect of any great tendency to animalism. A refined love of making others suffer has led them to vent inquisitionary tortures on insects, and the mania for pulling off the legs of flies and roasting beetles under spyglasses has been gradually extended to drowning mice in cages and seeing pigs killed. Time develops the germ; the cruel boy becomes the callous doctor or "sharp-practising" attorney, and the cruel girl becomes the cruel mother and often the frail divorcée. Drink and cards are an obsession with some; cruelty is just as much a matter of obsession with others. But the ingenuity of the occult brain rises to higher things; it rises to the subtlest form of invention when dealing with the artistic and literary temperament. I have been intimately acquainted with authors--well-known in the popular sense of the word--who have been obsessed in the oddest and often most painful ways. The constant going back to turn door-handles, the sitting in grotesque and untoward positions, the fondness for fingering any smooth and shiny objects, such as mother-of-pearl, develop into manias for change--change of scenery, of occupation, of affections, of people--change that inevitably necessitates misery; for breaking--breaking promises, contracts, family ties, furniture--but breaking, always breaking; for sensuality--sensuality sometimes venial, but often of the most gross and unpardonable nature. I knew a musician who was obsessed in a peculiarly loathsome manner. Few knew of his misfortune, and none abominated it more than himself. He sang divinely, had the most charming personality, was all that could be desired as a husband and father, and yet was, in secret, a monomaniac of the most degrading and unusual order. In the daytime, when all was bright and cheerful, his mania was forgotten; but the moment twilight came, and he saw the shadows of night stealing stealthily towards him, his craze returned, and, if alone, he would steal surreptitiously out of the house and, with the utmost perseverance, seek an opportunity of carrying into effect his bestial practices. I have known him tie himself to the table, surround himself with Bibles, and resort to every imaginable device to divert his mind from his passion, but all to no purpose; the knowledge that outside all was darkness and shadows proved irresistible. With a beating heart he put on his coat and hat, and, furtively opening the door, slunk out to gratify his hateful lust. Heaven knows! he went through hell.
