The union of man and woman is the flower of Nature. But, like the rose, it bears within it the seed from which some still more beautiful flower may result. No pair, however sublime their union, suppose that it is the best that could by any possibility at any time exist. An absolutely perfect union depends upon an absolutely perfect pair in absolutely perfect surroundings. And no one supposes that he himself is perfect or that the world around him is perfect. So there is in the pair a consciousness of imperfection, a vision of perfection, and a desperate yearning to be more perfect and to make the world more perfect. Deep and strong as the creative impulse itself is the impulse to improvement. It is due to this impulse that the mother reaches over her child with such loving care, strives to shield it from all harm, social as well as physical, and to give it a better chance than she herself enjoyed. It is due to this same impulse that the man works to leave his profession, his business, his science, his art, his country, better than he found it. It is due to this impulse also that men as a whole are driven to improve the whole Earth, to improve plants, flowers, trees, animals, men, and make the world a better place for their successors than it has ever been for them. The pair--even the most splendid pair that has ever wedded --have deep within them this perhaps unrecognised impulse to improvement. They know that the rose can only bring forth roses, and that they can only bring forth men: they know that they cannot bring forth angels. But they know also that the rose, when wisely mated and its offspring provided with favourable surroundings of soil and air and sunshine, can give rise to blooms incomparably more perfect than itself. And they know that they themselves, if they have wisely mated, if they carefully tend their offspring and provide them with healthy, sunny, physical and social surroundings, can give rise, in generations to come, to unions of men and women incomparably more perfect than their own--as much more perfect as their union is than the unions of primitive men--richer in colour, more graceful in form, sweeter in fragrance, and of an altogether finer texture. * * *
