As the main agent in reproduction, the mother is most to be venerated on basic physiological grounds. As the main agent in developing love, the great human condition, she is the fountain of all our growth. As the beginner of industry, she is again a source of progress. As the first and final educator, she outwardly moulds what she has inwardly made; and, as she is the visible, tangible, lovable, living type of all this, the being in whose person is expressed the very sum of good to the individual, it is no wonder that our strongest, deepest, tenderest feelings cluster about the great word “mother.” Fully recognizing all this, it yet remains open to us to turn the light of science and the honest labor of thought upon this phase of human life as upon any other; to lay aside our feelings, and use our reason; to discover if even here we are justified in leaving the most important work of individual life to the methods of primitive instinct. Motherhood is but a process of life, and open to study as all processes of life are open. Among unconscious, early forms it fulfils its mission by a simple instinct. In the consciousness and complexity of human life it demands far more numerous and varied forces for its right fulfilment. It is with us a conscious process,—a process rife with consequences for good or evil. With this voluntary power come new responsibility and a need for new methods,—a need not merely to consider whether or not we will enter upon the duties of maternity, but how best we can fulfil them. Motherhood, like every other natural process, is to be measured by its results. It is good or evil as it serves its purpose. Human motherhood must be judged as it serves its purpose to the human race. Primarily, its purpose is to reproduce the race by reproducing the individual; secondarily, to improve the race by improving the individual. The mere office of reproduction is as well performed by the laying of eggs to be posthumously hatched as by many years of exquisite devotion; but in the improvement of the species we come to other requirements. The functions of motherhood have been evolved as naturally as the functions of nutrition, and each stage of development has brought new duties to the mother. The mother bird must brood her young, the mother cow must suckle them, the mother cat must hunt for them; and, in every varied service which the mother gives, its value is to be measured by its effect upon the young. To perform that which is most good for the young of the species is the measure of right motherhood, and that which is most good for the young is what will help them to a better maturity than that of their parents. To leave in the world a creature better than its parent, this is the purpose of right motherhood.
