_Unselfishness_ is the distinguishing feature of higher forms of love, and an unselfishness that had its origin not in conjugal union but in motherhood. Mr. Finck, in his study of love’s evolution, puts it thus: “The helpless infant could not survive without a mother’s self-sacrificing care, hence there was an important use for womanly sympathy which caused it to survive and grow while man immersed in wars and struggles remained hard of heart and knew not tenderness.... Selfishness in a man is perhaps less offensive because competition and the struggle for existence necessarily foster it.” (Henry Finck’s _Primitive Love_, pp. 160–161.) The social need for a specialized unselfishness has tended to differentiate the sexes emotionally, and in process of building up the entire structure of social life the pressure of outward forces has carried this differentiation further. I am not then traversing the natural laws of evolution when I assume that all questions relating to women are at this date pre-eminently important. The population problem, as I have shown, can only be solved through a diminution of the birth-rate, and throughout the British nation the family group is breaking up. It is disintegrating especially in the upper and middle classes. The movement towards industrial socialism is the outcome of masculine thought and energy. Man is its mainspring, although many thoughtful women take part in it. Conversely, the house-ruler, woman, must be the mainspring of a movement towards domestic socialism, although no success will accrue without the steadfast aid and co-operation of man. That some women are already fitted to begin this great work is evident from much of our female public service. Let me quote some words recently spoken of lady-workers by a male critic, Mr. H. W. Massingham: “They have moral courage and refinement. They do not tire more easily than men; they do not shirk the detail work; they take to drudgery.” Pioneers of the new movement must be religious in the best sense, i.e. their philosophy must bring into touch the worlds seen and unseen, inspiring action conducive to personal and universal happiness.
