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 a 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 addition the reader of Mr. Galton’s Hereditary Genius will probably say, “ability,” “capacity,” “genius,” and “energy.” The reader of Doctor Nordau will add “sanity.” And the reader of Mr. Archdall Reid will round up the list with “immunity” from dipsomania and all contagious diseases. “Let us mark our human beings,” the reader of that way of thinking will suggest, “let us give marks for ‘health,’ for ‘ability,’ for various sorts of specific immunity and so forth, and let us weed out those who are low in the scale and multiply those who stand high. This will give us a straight way to practical amelioration, and the difficulty you are trying to raise,” he urges, “vanishes forthwith.”

It would, if these points were really points, if “beauty,” “capacity,” “health,” and “sanity” were simple and uniform things. Unfortunately they are not simple, and with that fact a host of difficulties arise. Let me take first the most simple and obvious case of “beauty.” If beauty were a simple thing, it would be possible to arrange human beings in a simple scale, according to whether they had more or less of this simple quality—just as one can do in the case of what are perhaps really simple and breedable qualities—height or weight. This person, one might say, is at eight in the scale of beauty, and this at ten, and this at twenty-seven. But it complicates the case beyond the possibilities of such a scale altogether when one begins to consider that there are varieties and types of beauty having very wide divergences and made up of a varying number of elements in dissimilar proportions. There is, for example, the flaxen, kindly beauty of the Dutch type, the dusky Jewess, the tall, fair Scandinavian, the dark and brilliant south Italian, the noble Roman, the dainty Japanese—to name no others. Each of these types has its peculiar and incommensurable points, and within the limits of each type you will find a hundred divergent, almost unanalyzable, styles, a beauty of expression, a beauty of carriage, a beauty of reflection, a beauty of repose, arising each from a quite peculiar proportion of parts and qualities, and having no definable relation at all to any of the others. If we were to imagine a human appearance as made up of certain elements, a, b, c, d, e, f, etc., then we might suppose that beauty in one case was attained by a certain high development of a and f, in another by a certain fineness of c and d, in another by a delightfully subtle ratio of f and b.

A, b, c, d, e, F, etc.
a, b, c, d, e, f, etc.
a, b, c, d, e, F, etc.,

might all, for example, represent different types of beauty. Beauty is neither a simple nor a constant thing; it is attainable through a variety of combinations, just as the number 500 can be got by adding or multiplying together a great variety of numerical arrangements. Two long numerical formulae might both simplify out to 500, but half the length of one truncated and put end on to the truncated end of the other, might give a very different result. It is quite conceivable that you might select and wed together all the most beautiful people in the world and find that in nine cases out of ten you had simply produced mediocre offspring or offspring below mediocrity. Out of the remaining tenth a great majority would be beautiful simply by “taking after” one or other parent, simply through the predominance, the prepotency, of one parent over the other, a thing that might have happened equally well if the other parent was plain. The first sort of beauty (in my three formulae) wedding the third sort of beauty, might simply result in a rather ugly excess of F, and again the first sort might result from a combination of

a, b, c, d, e, F, etc.,
and
A, b, c, d, e, f, etc.,

neither of which arrangements, very conceivably, may be beautiful at all when it is taken alone. In this respect, at any rate, personal value and reproductive value may be two entirely different things.

Now what the elements of personal aspect really are, what these elements a, b, c, d, e, f, etc., may be, we do not know with any sort of exactness. Possibly height, weight, presence of dark pigment in the hair, whiteness of skin, presence of hair upon the body, are simple elements in inheritance that will follow Galton’s arithmetical treatment of heredity with some exactness. But we are not even sure of that. The height of one particular person may be due to an exceptional length of leg and neck, of another to an abnormal length of the vertebral bodies of the backbone; the former may have a rather less than ordinary backbone, the latter a stunted type of limb, and an intermarriage may just as conceivably (so far as our present knowledge goes) give the backbone of the first and the legs of the second as it may a very tall person.
