[2] Vol. ii. of the fourth edition of ``The Criminal'' (1889) is specially concerned with the epileptic and idiotic criminal (referred to alcoholism, hysteria, mattoidism) whether occasional or subject to violent impulse; whilst vol. i. is concerned only with congenital criminality and moral insanity.
But these original faults in no way obscure the two following noteworthy facts—that within a few years after the publication of ``The Criminal'' there were published, in Italy and elsewhere, a whole library of studies in criminal anthropology, and that a new school has been established, having a distinct method and scientific developments, which are no longer to be looked for in the classical school of criminal law.
I.
What, then, is criminal anthropology? And of what nature are its fundamental data, which lead us up to the general conclusions of criminal sociology?
If general anthropology is, according to the definition of M. de Quatrefages, the natural history of man, as zoology is the natural history of animals, criminal anthropology is but the study of a single variety of mankind. In other words, it is the natural history of the criminal man.
Criminal anthropology studies the criminal man in his organic and psychical constitution, and in his life as related to his physical and social environment—just as anthropology has done for man in general, and for the various races of mankind. So that, as already said, whilst the classical observers of crime study <p 5>various offences in their abstract character, on the assumption that the criminal, apart from particular cases which are evident and appreciable, is a man of the ordinary type, under normal conditions of intelligence and feeling, the anthropological observers of crime, on the other hand, study the criminal first of all by means of direct observations, in anatomical and physiological laboratories, in prisons and madhouses, organically and physically, comparing him with the typical characteristics of the normal man, as well as with those of the mad and the degenerate.
Before recounting the general data of criminal anthropology, it is necessary to lay particular stress upon a remark which I made in the original edition of this work, but which our opponents have too frequently ignored.
We must carefully discriminate between the technical value of anthropological data concerning the criminal man and their scientific function in criminal sociology.
For the student of criminal anthropology, who builds up the natural history of the criminal, every characteristic has an anatomical, or a physiological, or a psychological value in itself, apart from the sociological conclusions which it may be possible to draw from it. The technical inquiry into these bio- psychical characteristics is the special work of this new science of criminal anthropology.
Now these data, which are the conclusions of the anthropologist, are but starting-points for the criminal sociologist, from which he has to reach his legal and social conclusions. Criminal anthropology is to <p 6>criminal sociology, in its scientific function, what the biological sciences, in description and experimentation, are to clinical practice.
