By pointing out the marked racial change resulting from the action of selection, which shows itself every ten years in the production of some new variety of dog or pigeon, and every year in the production of many varieties of flowering plants, we can convince the uninstructed by ocular demonstration which they cannot deny. They must learn to look upon mankind as organically related to other animals, and it must be pointed out to them that the facts of human evolution are in the main similar to, and form but a section of, the facts of general evolution. It must be pointed out that in many families there are perhaps one or two of the children, bred under conditions like the rest, who are delicate, of ungovernable temper, or have some deformity. They will know by experience that these children will in their turn have children like themselves, and the wonderful benefit to the race which would result from the selection of the strongest in mind and body as race producers will of necessity follow. It would then be possible to develop a strong public feeling against any marriages contracted by obviously sickly people, for the suffering which may be inflicted by producing sickly offspring may reasonably be urged against those who would otherwise be willing to gratify their convenience or personal predilection, and perhaps eventually this might lead to prohibition of such marriages. It should be pointed out that temperaments, and moral and mental qualities, are transmitted just as surely as physical traits; that all, in fact, of the qualities of the future race will depend upon those which are blended together to-day in parenthood. It follows, therefore, that the greatest of all responsibilities is taken by the assumption of parenthood, and everyone may well ask himself or herself, before undertaking it, Will the world be better for any more of me? _The End and Aim of Marriage._ To-day we are apt to be cautious before marriage; we are very keen to be assured on the question of dowry, and one hears of private inquiry as to money matters through the family solicitor. We have pride in so-called “birth,” which is of very fictitious biological value, and think much of an alliance with one of good family. Men and women have already, therefore, learned to tread with caution on the pathway which leads towards the altar, and for the most part no longer give full play to vanity and passion pure and simple. We are prepared, therefore, to look before we leap, but we look in the wrong direction, we avoid inconvenience and plunge into catastrophe. The reason for this is that we are but partially educated in the real ends and aims of life, and do not know the course which leads to ultimate success provided we follow it. _Our False Ideas regarding Marriage._
