But that the trepanning of the skull in a case of traumatic epilepsy or that ovariotomy can cure the central nervous system and, therefore, restore the character and even the morality of the individual, these are facts that can be unknown only to a metaphysical idealist, an opponent of the positivist school of criminology.
And yet this is how M. Garofalo comments on my induction (p. 240); this commentary is reproduced again on pages 95, 100, 134 and 291:
"It is truly extraordinary that M. Ferri, notwithstanding that criminal anthropology, of which he has so long been (and still is) one of the most ardent partisans, should have allowed himself to be so blinded by the mirage of socialism. A statement such as that which I have quoted at first leaves the reader stunned, since he sees absolutely no connection between nervous diseases and collective ownership. It would be just as sensible to say that by the study of algebra one can make sure of one's first-born child being a male." How exactly like the remarks of the Review of jurisprudence concerning the case of the removal of the ovaries!
Now, let us see whether it is possible, by a supreme effort of our feeble intellect, to point out a connection between nervous diseases and collective ownership.
That poverty, i. e., inadequate physical and mental nutrition—in the life of the individual and through hereditary transmission—is, if not the only and exclusive cause, certainly the principal cause of human degeneration, is henceforth an indisputable and undisputed fact.
That the poverty and misery of the working class—and notably of the unhappy triad of the unemployed, the displaced [by machinery, trusts, etc.] and those who have been expropriated by taxation—is destined to disappear with the socialization of the land and the means of production:—this is the proposition that socialism maintains and demonstrates.
It is, therefore, natural that under the socialist régime, with the disappearance of poverty, there should be eliminated the principal source of popular degeneracy in the epidemic and chronic forms of diseases, crimes, insanity and suicide; this can, moreover, be seen at present—on a small scale, but clearly enough to positively confirm the general induction—since diseases [nervous], crimes, insanity and suicide increase during famines and crises, while they diminish in years when the economic conditions are less wretched.
There is still more to be said. Even among the aristocracy and bourgeoisie, no one can fail to see that the feverish competition and cannibalistic strife of our present system beget nervous disorders, crime and suicide, which would be rendered quite unnecessary by the establishment of a socialist régime, which would banish worry and uneasiness for the morrow from the human race.
There then you see established the relation between collective ownership and nervous diseases or degeneration in general, not only among the popular and more numerous classes, but also in the bourgeois and aristocratic classes.
It is, indeed, astonishing that the anti-socialist prejudice of M. Garofalo should have been strong enough to cause him to forget that truth which is nevertheless a legitimate induction of criminal biology and sociology, the truth that besides the congenital criminal there are other types of criminals who are more numerous and more directly produced by the vitiated social environment. And, finally, if the congenital criminal is not himself the direct product of the environment, he is indirectly its product through the degeneration begun in his ancestors, by some acute disease in some cases, but by debilitating poverty in the majority of cases, and afterward hereditarily transmitted and aggravated in accordance with the inexorable laws discovered by modern science.
