When I consider the evidence which I have before me, which is almost exclusively from the very best type of women, and when I observe that the most generally perfected, and finest women of my acquaintance, and they in particular, desire occasional moderate intercourse during pregnancy, I feel that one has a guide to what is best for the race. In these women and the conduct which their needs inspire, we have an indication of the truest and highest standard of all. The deviations of conduct may at last return from both the grossness of abuse and the reaction from it, and settle in the right and middle path. After the excessively virtuous, and perhaps undersexed type of woman, in contrast to the totally base attitude of the earlier and coarser type of man, has made the thoughtful speed from baseness to an ascetic absence of unions, we should be led back by these well developed and well balanced and noble minded women to the right and middle way. In this the spontaneous impulse of the responsible mother will be the guide for her husband and will benefit all three concerned. For, let us realize what a profound mystical symbol is enacted when the union is not that of a single man and woman, but of that holy trinity the father, the mother and the unborn child. _Only_ during these brief sacred months can the three be united in such exquisite intimacy, and during all these months when the child is forming, it is only in the few infrequent embraces of subdued passion that the husband and father-to-be can come truly close to his child, that he can, through additions to her system from his own, assist the mother in her otherwise solitary task of endowing it with everything its growth demands. Every woman who is bearing a child by a man whom she loves deeply, longs intensely that its father should influence it as much as it is possible for him to do: in this way _and in this way alone_ can he give it of the actual substance of his body. This view of mine, in the present crude state of scientific knowledge must, of course, be stated as an hypothesis, but it will be proved later on when science is sufficiently subtle to detect the actual microscopic exchange of particles which takes place during proper and prolonged physical contact in the sex union.
