It is precisely on the ground of this negative, yet real efficacy of punishments, especially whilst they are being carried out, that, whilst we appreciate the mitigation of punitive discipline which has been <p 110>achieved by the classical school, we believe, on the other hand, that their abbreviation of the term of punishments is altogether mistaken and dangerous. We admit that punishment ought not to be an arbitrary and inhuman torture, and for this reason we have no sympathy with the system of solitary confinement, now so much in fashion with the classical jurists and prison authorities, precisely because it is inhuman, as well as unwise and needlessly expensive. It is a psychological absurdity and a social danger, which nevertheless underlies the new Italian penal code, that punishment ought to consist more and more in a short isolation of the prisoner. For, setting aside the well-known results of short punishments, such as corruption and recidivism, it is evident that in this way punishment is deprived of its main element of negative efficiency against crime, as well as of its effect in preventing crime during the incarceration of the criminal. II. Since punishments, instead of being the simple panacea of crime which popular opinion, encouraged by the opinions of classical writers on crime and of legislators, imagine them, are very limited in their deterrent influence, it is natural that the criminal sociologist should look for other means of social defence in the actual study of crimes and of their natural origin. We are taught by the everyday experience of the <p 111>family, the school, associations of men and women, and the history of social life, that in order to lessen the danger of outbreaks of passion it is more useful to take them in their origin, and in flank, than to meet them when they have gathered force.
