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 regime, 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 regime, 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.
