Hitherto, then, the classical school stands alone, with varying shades of opinion, but one and distinct as a method, and as a body of principles and consequences. And whilst it has achieved its aim in the most recent penal codes, with a great, and too frequently an excessive diminution of punishments, so in respect of theory, in Italy, Germany, and France it has crowned its work with a series of masterpieces amongst which I will only mention Carrara's ``Programme of Criminal Law.'' As the author tells us in one of his later editions, from the <_a!> priori_ principle that ``crime is a fact dependent upon law, an infraction rather than an action,'' he deduced--and that by the sheer force of an admirable logic--a complete symmetrical scheme of legal and abstract consequences, wherein judges are compelled, whether they like it or not, to determine the position of every criminal who comes before them. But now the classical school, which sprang from the marvellous little work of Beccaria, has completed its historic cycle. It has yielded all it could, and writers of the present day who still cling to it can only recast the old material. The youngest of them, indeed, are condemned to a sort of Byzantine discussion of <p xx>scholastic formulas, and to a sterile process of scientific rumination. And meantime, outside our universities and academies, criminality continues to grow, and the punishments hitherto inflicted, though they can neither protect nor indemnify the honest, succeed in corrupting and degrading evil-doers. And whilst our treatises and codes (which are too often mere treatises cut up into segments) lose themselves in the fog of their legal abstractions, we feel more strongly every day, in police courts and at assizes, the necessity for those biological and sociological studies of crime and criminals which, when logically directed, can throw light as nothing else can upon the administration of the penal law. CHAPTER I. THE DATA OF CRIMINAL ANTHROPOLOGY. THE experimental school of criminal sociology took its original title from its studies of anthropology; it is still commonly regarded as little more than a ``criminal anthropology school.'' And though this title no longer corresponds with the development of the school, which also takes into account and investigates the data of psychology, statistics, and sociology, it is none the less true that the most characteristic impetus of the new scientific movement was due to anthropological studies. This was conspicuously the case when Lombroso, giving a scientific form to sundry scattered and fragmentary observations upon criminals, added fresh life to them by a collection of inquiries which were not only original but also governed by a distinct idea, and established the new science of criminal anthropology.
