THE PROBLEM OF THE BIRTH SUPPLY
we are, as a matter of fact, not a bit clear what points to breed for and what points to breed out.
The analogy with the breeder of cattle is a very misleading one. He has a very simple ideal, to which he directs the entire pairing of his stock. He breeds for beef, he breeds for calves and milk, he breeds for homogeneous docile herd. Towards that ideal he goes simply and directly, slaughtering and sparing, regardless entirely of any divergent variation that may arise beneath his control. A young calf with an incipient sense of humour, with a bright and inquiring disposition, with a gift for athleticism or a quaintly-marked hide, has no sort of chance with him at all on that account. He can throw these proffered gifts of nature aside without hesitation. Which is just what our theoretical breeders of humanity cannot venture to do. They do not want a homogeneous race in the future at all. They want a rich interplay of free, strong, and varied personalities, and that alters the nature of the problem absolutely.
This the reader may dispute. He may admit the need of variety, but he may argue that this variety must arise from a basis of common endowment. He may say that in spite of the complication introduced by the consideration that a divergent variation from one ideal may be a divergence towards another ideal, there remain certain definable points that could be bred for universally, for all that.
What are they?
There will be little doubt he will answer, "Health." After that probably he may say, "Beauty." In
