“It is as important that the right people should be born as that the wrong people should not be born. By the ” right people ” I mean not those who, in Herbert Spencer’s phrase, are the “fittest to survive,” but those who give most promise of ” civic worth,” that is to say, will be most likely to be at once useful to themselves in the way of enjoyment and self-support, and also useful to the community at large. Sound health, a sufficient amount of energy, a well-balanced brain, are obviously desirable, nay, necessary ingredients-good moral training should supply the rest. ” Crackanthorpe 1909
