“We civilized men do our utmost to check the process of elimination; we build asylums for the imbecile, the maimed, and the sick .... There is reason to believe that vaccination has preserved thousands... Thus the weak members of civilized societies propagate their kind. No one who has attended to the breeding of domestic animals will doubt that this must be highly injurious to the race of man. It is surprising how soon a want of care, or care wrongly directed, leads to the degeneration of a domestic race; but excepting in the case of man itself, hardly any one is so ignorant as to allow his worst animals to breed.”
