That is to say, when you tell Tommy not to hit his sick sister on the temple, you must make sure of the presence of some Nietzscheite professor, who will explain to him that such a course might possibly serve to eliminate the unfit.

What would happen to a child brought up on Shaw's principle I cannot conceive; I should think he would commit suicide in his bath."
