Brief reference was made in a previous chapter to woman's great function of choosing the fathers of the future. Here we must discuss, at due length, her choice of a companion for life. It is repeatedly argued, by critics of any new idea, that the eugenist, in his concern for the race, is blind to the natural interests and needs of the individual; that "we are all to be married to each other by the police," as an irresponsible jester has declared; that the sanctities of love are to be profaned or its imperatives defied. Even serious and responsible persons assume that there is here a necessary antagonism between the interests of the race and those of the individual,--that the girl would, presumably, choose one man to be her love and companion and partner for life, but another man as the father of her children. There are those whom it always rejoices to discover what they regard as antinomies and contradictions in Nature, and they verily prefer to suppose that there is in things this inherent viciousness, which sets eternal war between one set of obligations, one set of ideals, and another. But Nature is not made according to the pattern of our misunderstandings. We have seen that all individuals are constructed by Nature for the future. We are certainly right to regard them as also ends in themselves, but Nature conceived and fashioned them with reference to the future. In so far as marriage has a natural sanction and foundation--than which nothing is more certain--we may therefore expect to discover that the interests of the individual and of the race are indeed one. In a word, the man who is most worthy to be chosen as a father of the future is always the most worthy and, in the overwhelming majority of cases, is also the most individually suitable, to be chosen as a partner and companion for life. Let the girl choose wisely and well for her own sake and in her own interests. If, indeed, she does so, the future will be almost invariably safeguarded. Of course it is to be understood that we are here discussing general principles. Everyone knows that cases exist, and must continue to exist, where an opposition between the interests of the race and those of the individual cannot be denied. Some utterly unsuspected hereditary strain of insanity, for instance, may show itself or be discovered in the ancestry of an individual to whom a member of the opposite sex has already become devoted. I fully admit the existence of such exceptions, but it must be insisted that they are exceptions, and that they do not at all invalidate the general truth that if a girl really chooses the best man, she is choosing the best father for her children.
