This school had, and still has, a practical purpose, namely, to diminish all punishments, and to abolish a certain number, by a magnanimous reaction of humanity against the arbitrary harshness of medi<ae>val times. It had also, and still has, a method of its own, <p xviii>namely, to study crime from its first principles, as an abstract entity dependent upon law. Here and there since the time of Beccaria another stream of theory has made itself manifest. Thus there is the correctional school, which Roeder brought into special prominence not many years ago. But though it flourished in Germany, less in Italy and France, and somewhat more in Spain, it had no long existence as an independent school, for it was only too easily confuted by the close sequence of inexorable facts. Moreover, it could do no more than oppose a few humanitarian arguments on the reformation of offenders to the traditional arguments of the theories of jurisprudence, of absolute and relative justice, of intimidation, utility, and the like. No doubt the principle that punishment ought to have a reforming effect upon the criminal survives as a rudimentary organ in nearly all the schools which concern themselves with crime. But this is only a secondary principle, and as it were the indirect object of punishment; and besides, the observations of anthropology, psychology, and criminal statistics have finally disposed of it, having established the fact that, under any system of punishment, with the most severe or the most indulgent methods, there are always certain types of criminals, representing a large number of individuals, in regard to whom amendment is simply impossible, or very transitory, on account of their organic and moral degeneration. Nor must we forget that, since the natural roots of crime spring not only from the individual organism, but also, in large measure, from its physical and social environment, <p xix>correction of the individual is not sufficient to prevent relapse if we do not also, to the best of our ability, reform the social environment. The utility and the duty of reformation none the less survive, even for the positive school, whenever it is possible, and for certain classes of criminals; but, as a fundamental principle of a scientific theory, it has passed away.
