“The statement is made that the two brothers have been subjected to the same environmental influences merely because they have been brought up in the same house, taught in the same school, fed and clothed alike. Yet the mere fact of having been born first or second is not without importance. To have been reared with an older or with a younger brother constitutes a difference of environment that may contribute powerfully to differentiate character. Add to this the differences of environment proceeding from nurses, servants, diseases, games, etc., and you will have opened headings under which may be classed differences innumerable. There are no small things in such a matter. Biographies as now written are no more than outlines when one thinks of what truly psychological biographies ought to be. To have been taught in the same college in the case of two brothers is a similarity that may, and certainly does, conceal the greatest differences. They have not had the same teachers, the same fellow-pupils, nor, above all, the same comrades. Between the education given, and that actually received, the difference may be great.... “The influences that act upon the child outside of the curriculum have the more chance to be effective, since the curriculum is carried out in the less agreeable manner.” [109] In consequence of what has been said, I believe that the conclusion of Professor Ferri that there are anthropological factors of crime, is too hasty. But there are still other objections to be urged to it. Let us suppose that two persons who live, and have lived, in the same circumstances are in a position to commit a very advantageous crime, and their morality does not prevent. At the moment when the time comes to act, one commits the crime and the other does not—he lacks the courage. Courage, then, is a factor of crime, and the lack of it a factor of virtue! Not so, that depends upon circumstances. In another case, he who commits a crime is stupid, and does not consider the risk, and he who does not commit it is a crafty man. Stupidity, then, is a factor of crime, and craft of virtue! Not so, that depends upon circumstances. The reverse is also true, probably more true still. Thousands of great criminals so far from being stupid have had something of the genius in them.
