According to my conception of the word, it is love on the contrary, which will win the victory by the relative weakening of impulse, and by scientific analysis of the same. Men will no longer mistake impulse for love. Of course this impulse is always present in love, but in the same way in which the sculpture of the cave man is present in the work of Michael Angelo. Man will then, with all the powers of his being, be able to love, when love, according to the happy expression of Thoreau, is not a glow, but a light. Then he will see for the first time, what wealth life can have through love, when love becomes a happiness worthy of man because it becomes an æsthetic creation, a religious worship; when the completed unity of those who love is expressed in a new being,--a being that will some day be really grateful for the life it has received. Where the amelioration of the human race is concerned, the transformation of customs and feelings is always the essential thing. Influence of legislation in comparison with it is ever slight. But as has been said before, legislation has its role to play. Especially where there are diseases which can certainly be transmitted, society must interfere to restrict marriage. In Germany and America a good proposal has been made, for the period of transition in this direction. It is suggested that the law shall require as an obligatory condition for marriage, a certificate of a medical witness with complete data as to the health of both parties. Those who contract marriage will continue to have their freedom of choice but at least they would not enter ignorantly upon marriage as they do now, and expose themselves and their children to disastrous consequences. It appears to me to be at least as important for society to have a medical certificate as to capacity for marriage, as it is for military service. In the one case, we deal with giving life, in the other with taking it away. And although the latter has certainly been, up till now, regarded as a more serious occasion than the former, still an awakening social conscience should demand progress in this direction. It is conceivable that from this beginning new customs will develop; further legislation may be dispensed with; human beings will agree to sacrifice the most dangerous of all liberties, giving life to a defective offspring, while prohibition of marriage now would not hinder parenthood. For the great mass might continue, outside of marriage, to rob children of the possibilities of health and happiness, by burdening them with inherited diseases or bad tendencies.
