advantage, it would be well if we were to change our standpoint and examine our machinery at the point of application. A rock-drilling machine may be excellently invented and in the most perfect order except for a want of hardness in the drill, and yet there will remain an unpierced rock as obdurate as the general public to so many of our innovations.
I believe that if a canvass of the entire civilized world were put to the vote in this matter, the proposition that it is desirable that the better sort of people should intermarry and have plentiful children, and that the inferior sort of people should abstain from multiplication, would be carried by an overwhelming majority. They might disagree with Plato’s methods, [Footnote: The Republic , Bk. V.] but they would certainly agree to his principle. And that this is not a popular error Mr. Francis Galton has shown. He has devoted a very large amount of energy and capacity to the vivid and convincing presentation of this idea, and to its courageous propagation. His Huxley Lecture to the Anthropological Institute in 1901 [Footnote: Nature , vol. lxiv. p. 659.] puts the whole matter as vividly as it ever can be put.
