But there is another aspect of Eugenics. Human eugenics need not be, and is not likely to be, a cold-blooded selection of partners by some outside scientific authority. But it may be, and is very likely to be, a slowly growing conviction--first among the more intelligent members of the community and then by imitation and fashion among the less intelligent members--that our children, the future race, the torch-bearers of civilization for succeeding ages, are not the mere result of chance or Providence, but that, in a very real sense, it is within our power to mould them, that the salvation or damnation of many future generations lies in our hands since it depends on our wise and sane choice of a mate. The results of the breeding of those persons who ought never to be parents is well known; the notorious case of the Jukes family is but one among many instances. We could scarcely expect in any community that individuals like the Jukes would take the initiative in movements for the eugenic development of the race, but it makes much difference whether such families exist in an environment like our own which is indifferent to the future of the race, or whether they are surrounded by influences of a more wholesome character which can scarcely fail to some extent to affect, and even to control, the reckless and anti-social elements in the community. In considering this question, therefore, we are justified in putting aside not only any kind of human breeding resembling the artificial breeding of animals, but also, at all events for the present, every compulsory prohibition on marriage or procreation. We must be content to concern ourselves with ideals, and with the endeavour to exert our personal influence in the realization of these ideals. III
