But yet possibly there is even something more in the whole thing, on and beyond what is here indicated. In the extraordinary and often agonizing experiences attending the matter of ‘falling in love,’ great changes, as we have already suggested, are being wrought in the human being. Astounding inner convulsions and conversions take place—rejections of old habits, adoptions of new ones. The presence of the beloved exercises this magical selective and reconstructive influence—and that independently to a large degree of whether the relation is a happy and ‘successful’ one, or whether it is contrary and unsuccessful. The main thing is contact, and the coming of one person into touch with the other. We have seen, in the case of the Protozoa, the amazing fact of the ‘maturation-divisions’ and the ‘extrusion of polar bodies’ as a preparation for conjugation—how, when the two cells which are about to unite approach each other, changes take place already before they come into contact, and half the chromatin elements from one cell are expelled, and half the chromatin elements also from the other. What the exact nature of this division and extrusion may be is a thing not yet known, but there seems every reason to believe that it is of such a character as to leave the residual elements on both sides complementary to one another—so that when united they shall restore the total attributes of the race-life, only perhaps in a new and unprecedented combination. The Protozoa in fact ‘prepare’ themselves for conjugation and realization of the race-life, by casting out certain elements which would interfere with this realization. And we may well ask ourselves whether in the case of Man the convulsions and conversions of which we have spoken have not the same purpose and result, or something much resembling it. Whatever really takes place in the unseen world in the case of human Love, we cannot but be persuaded that it is something of very far-reaching and long-lasting import; and to find that the process should often involve great pain to the little mortals concerned seems readily conceivable and by no means unnatural.
