The aim of love, as understood by Ellen Key, is always marriage and the child, and as soon as the child comes into question society and the State are concerned. Before fruition, love is a matter for the lovers alone, and the espionage, ceremony, and routine now permitted or enjoined are both ridiculous and offensive. "The flower of love belongs to the lovers, and should remain their secret; it is the fruit of love which brings them into relation to society." The dominating importance of the child, the parent of the race to be, alone makes the immense social importance of sexual union. It is not marriage which sanctifies generation, but generation which sanctifies marriage. From the point of view of "the sanctity of generation" and the welfare of the race, Ellen Key looks forward to a time when it will be impossible for a man and woman to become parents when they are unlikely to produce a healthy child, though she is opposed to Neo-Malthusian methods, partly on aesthetic grounds and partly on the more dubious grounds of doubt as to their practical efficiency; it is from this point of view also that she favours sexual equality in matters of divorce, the legal assimilation of legitimate and illegitimate children, the recognition of unions outside marriage,--a recognition already legally established under certain circumstances in Sweden, in such a way as to confer the rights of legitimacy on the child,--and she is even prepared to advise women under some conditions to become mothers outside marriage, though only when there are obstacles to legal marriage, and as the outcome of deliberate will and resolution. In these and many similar proposals in detail, set forth in her earlier books, it is clear that Ellen Key has sometimes gone beyond the mandate of her central conviction, that love is the first condition for increasing the vitality alike of the race and of the individuality, and that the question of love, properly considered, is the question of creating the future man. As she herself has elsewhere quite truly pointed out, practice must precede, and precede by a very long time, the establishment of definite rules in matters of detail.
