Few, indeed, are the mothers who love other women's children. As "mother" is a synonym for all kindness, so "stepmother" is a synonym for all unkindness. Folklore and fairy-tale indicate old fact. Infant helplessness and orphan need are not only what appeals to the mother--it is most the blood-tie, the physical relation.
Civilisation and Christianity teach us to care for "the child," motherhood stops at "my child."
Still, in the home we do find the nursery of all the lines of family affection, parental, filial, fraternal, and these are good. Hearts able to love ten could more easily take in twenty; the love of one's own parents spread to our present care for the aged; the power of loving grew, and, as soon as it overstepped the limits of the home, it grew more rapidly. We have learned to love our neighbours--if not as ourselves, at least, better than strangers. We have learned to love our fellow-citizens, fellow-craftsmen, fellow-countrymen. To-day the first thrills of international good-will are stealing across the world--and we are extending our sympathy even to the animals.
All this beautiful growth of love began at home; but the influence of the home, as it now exists upon the growth, is not so wholly gratifying. The love that we call human, the love of one another, the love Christ teaches us, is extra-domestic. We are not told, "Inasmuch as you have done it to your own families you have done it unto me." We are not exhorted to an ever-increasing intensity of devotion to our own blood-relations.
Both the teaching of our religion and the tendency of social progress call for a larger love, and the home, in its position of arrested development, primitive industry, and crippled womanhood, tends rather to check that growth than to help it. The man's love for his family finds expression in his labour for other people--he serves society, and society provides for him and his dear ones; so good will spreads and knits; comradeship and fellow-feeling appear, friendship brings its pure height of affection; this is the natural line of development in the great social virtue, love.
But the woman, still expressing her love for her family in direct personal service, misses all that. The primitive father, to feed the child, went forth himself and killed some rabbit--and the primitive mother cooked it: love, in grade A. The modern father, to feed his child, takes his thousandth part in some complex industry, and receives his thousand-fold share of the complex products of others' industry, and so provides for the child far more richly than could the savage: love, in grade Z. But the modern mother--if we can call her so by courtesy--to feed her child still does nothing but cook for it, still loves in grade A; and the effect of that persistence of grade A is to retard the development of grade Z. Mother-love is the fountain of all our human affection; but mother-love, _as limited by the home_, does not have the range and efficacy proper to our time. The home, as at present maintained, checks the growth of love.
