On the social side, a parent who has children is forced to live in all the social world around him. The water-supply, the sewage, pure foods, vacant lots, paving, fast driving in the streets, police protection, undesirable residents, saloons and churches, schools and libraries--everything that touches the social well-being--touches him vitally and imperatively. The foot-loose celibate can always go away. The parent finds it difficult to leave the place where he has planted his roof-tree. Of course, there are many unmarried people, and people who are childless, who live this domestic life vicariously through friends or other people's children. One cannot but be grateful that life is so organized that no woman can be entirely shut off, unless she wills it, from the fructifying life that knits together the generations of the old and the young. Ideals are very powerful in determining conduct, and the ideals of extreme individualism, now so constantly presented by certain leaders among emancipated women, must bear bitter fruit for an army of women in the future. While the women are young, ambition and the charm of freedom bear them gaily along. Generally better educated than the men of their own class, habituated to a personal expenditure which would correspond with a large family expenditure, their intelligence prevents their falling desperately in love with the men whom they might marry. But in the thirties they have visions of the future which are deeply disturbing; and in the forties they face the tragedy of a lonely old age. Some men and women there must always be whose lives lack the fulfilment of family life because of ill health or the accidents of personal relations. But most women, if they are willing to pay the same price for a significant family life that they so gladly pay for professional success, will find the way open to live all of life. Why is it that women count it an honor to work and starve for an art, but dishonor to undergo privations for their children? All that is here said of women may be said of men, but the man's period of family life is longer than woman's, and the tragedy of lonely old age with him seems less overwhelming.
