Up to recent times the criminal has been regarded as a kind of algebraic formula, to use Professor Ferri’s expression; the punishment has been proportioned not to the criminal but to the crime. We are now learning to regard the criminal as a natural phenomenon, the resultant of manifold natural causes. We are striving to attain to scientific justice. We are seeking in every direction to ascertain what is the reasonable treatment of the eccentric and abnormal members of society, in their interest, and in the still higher interests of the society to which we belong. To seek for light in the fields of biology and psychology, of anthropology and sociology, has seemed to many a discouraging task. The results are sometimes so obscure; sometimes, it even seems, contradictory. In practice, it is said, such considerations count for nothing. Law must only concern itself with absolute certainties, with abstract formulæ, with geometrical routine. But human nature will not fit in with formulæ; when men and women are geometrical figures, an abstract legal system will answer all their needs. If the path lies through a jungle, what is the use of the best and straightest of roads that leads astray? If a critic were to point out to a biologist--to take another illustration from Ferri--the limitations of the microscope, he would be entitled to reply--But excuse me, however imperfect the microscope may be, would it be better to dispense with the microscope? Much less when we are dealing with criminals, whether in the court of justice or in the prison, or in society generally, can we afford to dispense with such science of human nature as we may succeed in attaining. CHAPTER VI. THE TREATMENT OF THE CRIMINAL. If, as now scarcely admits of question, every truly criminal act proceeds from a person who is, temporarily or permanently, in a more or less abnormal condition, the notion of “punishment” loses much of its foundation. We cannot punish a monstrosity for acting according to its monstrous nature. Moreover, who among us is perfectly normal, and what tribunal is entitled to punish? The verdict of science is one with that of Christianity--“Judge not.”
