We have maintained throughout this volume that complete self-realization is impossible for the half-units which we call men and women, when either lives alone. On every side of their natures they are complementary; and the unit of human life must be found in the family composed of a man and woman who love each other and the children born of their love. "There are two worlds below, the home and outside of it." It is in this unit, under the stress of sexual passion and maternal love, that all the finer forces of our civilization have had their origin. Unselfishness, devotion, pity and the higher altruisms all hark back to the home as their source.

But, meantime, evil counsels prevail and one hears everywhere of the antagonistic interests of men and women. There can be no real rivalry between a man's soul and his body, between science and religion, between man and woman. The trouble all rests back in the failure to realize the incompleteness of man or woman alone for any of the purposes of life. And there is that evil notion which still afflicts economics that when two trade one must lose. The fact is that, in all honest trade, buyer and seller gain alike; and fair exchange makes all who participate in it rich. It is so in all real relations between these half-creatures we call men and women. In agreement, association and coöperation lies strong and significant life for both. In antagonism, separation and competition lie arid, poor, mean lives, egotistic and conceited, vapid and fickle.

In primitive life, the family furnished a full and adequate career for men and women alike. The political life was the family life; each family was a religious group; families mustered for war; and each family maintained within itself a wide range of industrial activity. But, because this unit was so basal, because all later special developments of state, church and industry came from it, it was steadily perverted. Warped from its original purpose, it has served in turn, as we have seen, to define and secure all our later institutions until it has become the servant of state, church, social ambition, property and industrial advance. Marriage and the birthrate are seldom discussed to-day from the point of view of individual needs; but are almost always considered from the point of view of national and industrial efficiencies.

To-day men and women are confronted by two tempters which constantly lure them away from the complete living of the family; one is work, and the other is comfort. With the majority of people in our modern industrial democracies work uses up the hours and the energy of life. We have passed into a time when our habitual material needs are great, and the products of work are shamelessly diverted to the excessive uses of comparatively few individuals and groups. Hence millions of workers march along the narrow dark roads that lead through factories and farms to the grave. Only little patches of their nervous systems are ever used, but all their energy flows through these sections day after day, leaving their lives dull and empty.

Marriage for these workers means decreased earning power for the woman, with increased needs for the family, especially when the children come. As one watches the procession of young factory and shop women, with Sunday finery and some leisure, passing over into draggled factory mothers, with no finery and no leisure, one marvels at the strength of the forces with which nature drives them to their destiny. And yet, even with these hopeless workers, marriage and children mark the heights of life.

With others, who are economically freer, work has become an obsession. A Charles Darwin or a Herbert Spencer turns all of life's forces to shaping facts into science; our industrial leaders mint their hours into dollars; our reformers give up their lives that social conditions may be changed; our society leaders trade life for triumphs. Meantime we all know, or would know if we stopped to consider, that we are here to live life fully and significantly day by day. But domesticity takes time and effort, and so the hurrying specialist follows the narrow line of success until he or she becomes a machine for manufacturing generalizations, for painting pictures, for performing surgical operations or for merely getting money. The richest woman in America said with approval recently that her son was too busy to fall in love.

As industry drives the mass of workers and specialists away from life's deepest realizations, so the desire to become comfortable, physically and mentally, through avoiding the deeper experiences of life, robs many of those who have a large measure of economic freedom. In all periods of great wealth this disease of ease has afflicted mankind. Life more abundantly comes only at the price of vigorous living; and love travels always in company with anxiety. It would be well, says Cicero, to have children, were it not for the fear of losing them. Let a man apply this principle to wife, friends, possessions and enthusiasm in general and life sinks into utter worthlessness.

The love of ease among women is in a measure independent of the emancipation movement, but the entry of great numbers of young women into lines of independent livelihood has placed them in a condition where the ideals of a materialistic and commercial civilization appeal to them with great force. Many of them have been liberally educated and are living lives of independence. They lodge in flats or boarding houses where they have no responsibilities for the routine work connected with daily living. They carry their own latch-keys; and no one interferes with their friendships or their pleasures. They read the books they like, attend the theaters that appeal to them, and avoid people who bore them. One can easily understand why these young women hesitate before abandoning their easy conditions for the uncertain economic position of wife and mother, with a man whose career lies in the future. And yet here, as everywhere, one must lose one's life to gain it.

What then does daily association of a man and woman who belong together do for them? It gives gladness and peace, and these are fundamental conditions for all good and healthful living. It gives incentive to effort, for a man or woman dares not fail before the one he or she loves; but, in case of failure, it gives comfort and support, for love understands and credits intent and effort as highly as achievement. It complements the powers, for it gives four eyes, four hands and two minds with but one aim. And in this it does not simply multiply by two, but the blended powers are far more than two times one. It calls into activity all the gracious, artistic and altruistic powers of the soul. Surely these are gifts for which we may well forego some material comforts, may well work, and even face anxieties unafraid.

Each part of the human unit must educate the other to a realization of the fulness of life. This education is not entirely dependent on physical intimacy. It is the development of soul and spirit. It polishes the manners, cultivates the voice, broadens the judgments, sharpens the wit. It makes conversation an art and discussion significant. A woman-hating man or a man-hating woman is an unpolished and half-alive creature, whether he be a mediæval saint, or she a militant suffragette, or they both be simply commonplace egoists.
