All practices aimed at eugenics, any use of the human body or any of i — Eugenics

"Selective breeding can alter mans capacity to learn, to keep sane, to cherish justice or to be happy. There is no more certain and economical a way to improve mans environment as to improve his nature."

"Nobody wants to be caught agreeing with that monster, even in a single particular. The spectre of Hitler has led some scientists to stray from "ought" to "is" and deny that breeding for human qualities is even possible. But if you can breed cattle for milk yield, horses for running speed, and dogs for herding skill, why on Earth should it be impossible to breed humans for mathematical, musical or athletic ability? Objections such as "these are not one-dimensional abilities" apply equally to cows, horses and dogs and never stopped anybody in practice. I wonder whether, some 60 years after Hitlers death, we might at least venture to ask what the moral difference is between breeding for musical ability and forcing a child to take music lessons. Or why it is acceptable to train fast runners and high jumpers but not to breed them. I can think of some answers, and they are good ones, which would probably end up persuading me. But hasnt the time come when we should stop being frightened even to put the question?"

"We belong to a time in which culture is in danger of being destroyed by the means of culture."

"Let me lay emphasis on the opportunity now presented in the United States for observing and, if we are wise, aiding in what I think it fair to say is the grandest opportunity ever presented of developing the finest race the world has ever known out of the vast mingling of races brought here by immigration."

"The keystone of the new social structure, the pivotal factor of advancing civilization, the guide of the new religion, is biology; for man is an animal, and his characteristics, his requirements, and his reactions can be recorded and studied quite as carefully and precisely as those of any other animal."

"It was only the feeling that, at least in one or two aspects of Francis Galtons later life and of his scientific work, I could perhaps put his contributions to human knowledge more adequately than possibly one or another who might take up the task, if I resigned it, and who would hardly grasp the bearing of that long and intimate scientific correspondence between Galton, Weldon and myself, that I persevered in my endeavour to give some account of a life, wherein an important chapter of personal development must remain largely unrecorded."
