Written in the beginning of the 20th century, before the WW I, when this theme was the "topic of the hour", eugenics is the study of methods of improving genetic qualities by selective breeding. Exerpts: "The wisest thing in the world is to cry out before you are hurt. It is no good to cry out after you are hurt; especially after you are mortally hurt. People talk about the impatience of the populace; but sound historians know that most tyrannies have been possible because men moved too late. It is often essential to resist a tyranny before it exists. It is no answer to say, with a distant optimism, that the scheme is only in the air. A blow from a hatchet can only be parried while it is in the air." "The point here is that a new school believes Eugenics against Ethics. And it is proved by one familiar fact: that the heroisms of history are actually the crimes of Eugenics. The Eugenists' books and articles are full of suggestions that non-eugenic unions should and may come to be regarded as we regard sins; that we should really feel that marrying an invalid is a kind of cruelty to children. But history is full of the praises of people who have held sacred such ties to invalids." "A silent anarchy is eating out our society." "Now this is the first weakness in the case of the Eugenists: that they cannot define who is to control whom; they cannot say by what authority they do these things."
