But the woman who looks forward to motherhood as a possibility for herself, or the woman who is expecting to become a mother, should not, through an unlimited amount of voluntary work or of work forced upon her contrary to her will, sacrifice the capacities for life and work of an unborn generation, in such a way that she will bring into the world weak, invalid, or physically incapable children, who will later on be neglected. It does not occur to the dogmatic advocates of women's rights that their talk about the individual freedom of the woman to control her career, their contention that no limitation need restrict woman's power of deciding her own vocation, because they are married or are mothers, mean the most crying injury, not only to children, but to women themselves. For the demand of equality, where nature has made inequality, brings about the injury of the weaker factor. Equality is not justice. Often it is just the opposite, the most absolute injustice. The strongest reasoning will not convince those advocates of women's rights who discuss woman's labour from the old-fashioned level of individualism, unaffected by the social feeling of solidarity, which is the solution offered by our age. But fortunately protective legislation does not depend on the women who advocate the rights of women. The workingmen's movement, aided by women and men of all classes who are active in it, will carry through this legislation. The movement for the normal working day is steadily gaining ground. Experience has shown that, because of the greater intensity of the work done, just as much can be accomplished in a shorter as in a longer time. The first concern has been the work of children and of younger adults. The effect of factory life on the health of women themselves, as well as on their children, has excited general attention. In England first, then in other European countries, it has become recognised as necessary that a normal period of work should be laid down for women as well. The programme was and continues to be threefold:--a maximum working time for women's work; limitation, or, better still, the cessation of night work on the part of women; the prevention, too, of the work of women in mines and in certain other industries dangerous to health; finally the protection of women who are about to become mothers. In most European countries there is now a maximum working time fixed at eight to eleven hours. Night work, work in mines, and extra work, is either forbidden or considerably limited, and a rest period of three to eight weeks is established for women at childbirth.
