The principals in this discussion represent the prosecution (public or private) and the defence; and for these, as I cannot go into great detail, I will only mention one necessary reform. That is the institution of a sort of public defence, by a legal officer such as used to be found in certain of the Italian provinces, under the title of ``advocate of the poor,'' who ought to be on a par with the public prosecutor, and to be substituted for the present institution of the official defence, which is a complete failure. As for the actual discussion of evidence, when we have established the scientific rules of evidence, based upon expert acquaintance with criminal anthropology, and when we have eliminated all verbal contention over the precise measure of moral responsibility in the prisoner, the whole debate will be a criticism of the personal and material indications, of the determining motives, and the anthropological category to which the accused belongs, and of the consequent form of social defence best adapted to his physical and psychical character. The practical conclusion of the criminal trial is arrived at in the third stage, that of the decision on the evidence. So far as we are concerned, the criminal adjudication has the simple quality of a scientific inquiry, subjective and objective, in regard to the accused as a possible criminal, and in relation to the deed of which he is alleged to be the author. We naturally therefore require in the judge certain scientific <p 173>knowledge, and not merely the intuition of common sense. But as the consultation of the jury, by reason of its inseparable political aspect, must take place in private, we can only insist on the fundamental reform of the judicial organisation, which alone can realise the scientific principle of criminal adjudication. It was Garofalo who, in the earlier days of the positive school, urged that civil and criminal judges ought to be wholly distinct, and that the latter ought to be versed in anthropology, statistics, and criminal sociology, rather than in Roman law, legal history, and the like, which throw no light on the judgment of the criminal. Learned jurists, proficient in the civil law, are least fit to make a criminal judge, accustomed as they are by their studies to abstractions of humanity, looking solely to the juridical bearings, inasmuch as civil law is mostly ignorant of all that concerns the physical and moral nature of individuals. The demoralisation or uprightness of a creditor, for instance, has no influence for or against the validity of his credit.
