This is the problem of race.

Granted that one knows something of the parents, it is admissible to draw a conclusion about the child: any kind of offensive incontinence, any kind of sordid envy, or of clumsy self-vaunting--the three things which together have constituted the genuine plebeian type in all times--such must pass over to the child, as surely as bad blood; and with the help of the best education and culture one will only succeed in DECEIVING with regard to such heredity .-- And what else does education and culture try to do nowadays! In our very democratic, or rather, very plebeian age, "education" and "culture" MUST be essentially the art of deceiving--deceiving with regard to origin, with regard to the inherited plebeianism in body and soul.

An educator who nowadays preached truthfulness above everything else, and called out constantly to his pupils: "Be true! Be natural! Show yourselves as you are!"-- even such a virtuous and sincere ass would learn in a short time to have recourse to the FURCA of Horace, NATURAM EXPELLERE: with what results?
"Plebeianism" USQUE RECURRET.
