Obviously the existence of men of most various types is a necessity for any highly organised society. Even if eugenics were capable--as it is not--of producing a complete and balanced type, fit up to a point to turn out a satisfactory poem, a satisfactory symphony or a satisfactory sofa, the utmost could not be expected of such a man in any of these directions. In a word, as long as their activities are not anti-social, men cannot be of too various types. We require mystic and mathematician, poet and pathologist. Only, we want good specimens of each. “The aim of eugenics,” says Mr. Galton, “is to represent each class or sect by its best specimens; that done, to leave them to work out their common civilisation in their own way.... Special aptitudes would be assessed highly by those who possessed them, as the artistic faculties by artists, fearlessness of enquiry and veracity by scientists, religious absorption by mystics, and so on. There would be self-sacrificers, self-tormentors, and other exceptional idealists.” But at least it is better to have good rather than bad specimens of any kind, whatever that kind may be. Mr. Galton thinks that all except cranks would agree as to including health, energy, ability, manliness and courteous disposition amongst qualities uniformly desirable--alike in poet and pathologist. We should desire also uniformity as to the absence of the anti-social proclivities of the born criminal. So much uniformity being granted, let us have with it the utmost conceivable variety,--more, indeed, than most of us can conceive. This point, of course, is cardinal from the point of view of practice. No progress could be made with eugenics, it would be impossible even to form a Eugenics Education Society, if each of us were to regard the particular type he belongs to as the ideal, and were to seek merely to obtain the best specimens of that type. The doctrine that it takes all sorts to make a world--a doctrine very hard for youth to learn, yet unconsciously learnt by all who are capable of learning at all--must be regarded as a cardinal truth for the eugenist. But he wisely seeks good specimens rather than bad. Poets certainly, but not poetasters; jesters certainly, but not clever fools, who stand Truth on her head and then make street-boy gestures at her.
