But I think that this proposal of M. Liszt is acceptable only for commissions of supervision, or of the execution of punishment, such as already exist in several countries, with a view solely to prison administration and benevolence, and in which of course the experts of criminal anthropology ought to take part, who, as I have suggested, should be included in every preliminary criminal inquiry. As for the determination of the maximum and minimum in such a sentence, I believe it would not be practicable; the acting commissions might find it necessary to go beyond them, and it would be opposed to the very principle of indeterminate segregation. The reason given by M. Liszt, that with this provision the contrast with actual systems of punishment would be less marked, does not seem to me decisive; for the principle we maintain is so radically opposed to traditional theories and to legislative and judicial custom that this optional passing of the limits would avoid no difficulty, whilst it would destroy the advantages of the new system. In other words, when the conditions of the act committed and the criminal who has committed it show that the reparation of the damage inflicted is not sufficient by way of a defensive measure, the judge will only have to pronounce in his sentence an indefinite detention in the lunatic asylum, the prison for incorrigibles, or the establishments for occasional criminals (penal colonies, &c.). The execution of this sentence will be rendered <p 215>definite by successive steps, which will no longer be detached, as they now are, from the action of the magistrate, and taken without his knowledge, but will be a systematic continuation of his work. Permanent commissions for the supervision of punishment, composed of administrative functionaries, experts in criminal anthropology, magistrates, and representatives of the Public Prosecutor and the defence, would render impossible that desertion and oblivion of the convict which now follow almost immediately on the delivery of the sentence, with the execution of which the judge has nothing to do, except to see that he is represented. Pardon, or conditional liberation, or the serving of the full punishment, are all left at present to the chance of a blind official routine. These commissions would have great social importance, for they would mean on one hand the protection of society against imprudent liberation of the most dangerous criminals, and on the other hand the protection of the less dangerous against the danger of an imprisonment recognised as excessive and unnecessary.
