From the point of view of this book, all the efforts to open the doors of opportunity, through which women can pass into the man's world, are but preparations for the beginning of a journey. The sooner all such doors are opened the better, for then a great source of dangerous sex antagonism will pass away; and the energy of reformers will be set free to work out the difficult problem of supplementary sex adjustments. And meantime, sex remains the greatest mystery and the most powerful thing in human life. Its deeper values are lost sight of when men and women are warring over work, wages, and votes, just as the meaning of religion has been lost when priests and laity sought to advance their meanly selfish interests. But in the crises of life it always comes back. When a great ship founders in midocean, and but a third of the people can be saved, there is then no question of woman's rights. In the darkness of early morning, eager men's hands place their women in the life-boats and push them off. The poorest peasant woman takes precedence over any man. Almost every woman there would prefer to stay and die with her man; would glory in staying and dying if he might thus be saved; but in her keeping are the generations of the future, and she is weak, therefore the strong gladly stand back and go down to death. The solution of woman's place in the society of the future must be based on a recognition of the supplementary forces that send women to undesired safety while men die.
