Those who hold, as I do, that sexual behaviour concerns the community solely in so far as children are involved, must draw from this premise a twofold conclusion as regards the morality of the future. On the one hand, that love apart from children should be free, but on the other hand, that the procreation of children should be a matter far more carefully regulated by moral considerations than it is at present.
