The criminal craves for some powerful stimulus, excitement, uproar, to lift him out of his habitual inertia. That is why the love of alcohol is in all countries so strong among criminals. The man who is organised as we have seen the criminal to be must have some powerful stimulant to take him out of himself, to give him a joy which is otherwise beyond his grasp, and alcohol is the stimulant which comes easiest to hand. When, as frequently happens, he is the child of alcoholic parents, the craving for drink soon obtains morbid intensity. Crime and drink are intimately bound together, although we must beware of too unreservedly setting down drink as the cause of crime. Both crime and drink are the morbid manifestations of organic defects which for the most part precede birth. The abuse of alcohol is not, however, universal among criminals, at all events when any intellectual ability is required. “It would not do to drink in our business,” said a sharper to Lombroso. The criminal finds another strong form of excitement in gambling. The love of cards is even more widely spread among criminals than the love of drink. It frequently becomes a passion. Lauvergne tells of a band of criminals who played for two days without intermission. We hear of a French prisoner who gambled away his meagre rations of bread and wine and at last died of starvation; of another who in the excitement of the game forgot his approaching execution. To all forms of sexual excitement, natural and unnatural, criminals of both sexes resort, often from a very early age. The prison, in which the criminal is confined alone, or with persons of the same sex, serves to develop perverted sexual habits to a high degree. Prince Krapotkine, speaking of the moral influence of prisons on prisoners in France, writes:--“The facts which we came across during our prison life surpass all that the most frenzied imagination could invent. One must have been for long years in a prison, secluded from all higher influences and abandoned to one’s own and that of a thousand convicts’ imaginations, to come to the incredible state of mind which is witnessed among some prisoners. And I suppose that I shall say only what will be supported by all intelligent and frank governors of prisons, if I say that the prisons are _the_ nurseries for the most revolting category of breaches of moral law.”[63] There is unquestionable evidence that the same practices exist, notwithstanding all discipline, in English prisons. Such practices grow up chiefly as a means of excitement and diversion in vacuous lives. Love, in its highest and strongest forms, seems to be extremely rare. This is true even when love is the cause of the crime. The love, even when strong, remains rather brutal. When a man was asked if he really loved the woman for whose sake he had murdered her husband, he replied: “Oh, if you had seen her naked!”
