The devotion of the American settler to his family eventually necessitated his association for advantages which could be secured only through collective action. When he had subdued the land and established his home, when he commenced to raise farm products for market rather than primarily for support of the family, when better communication gave more contacts with the town and city, the farm family developed new wants and interests which could only be satisfied through association with others. We have already indicated the processes whereby the economic situation, religious life, public education, the need of local government, and the desire for recreational facilities, are inevitably drawing the people of the countryside together at the natural centers into communities. The locality group is again recognized as essential for the best organization of rural life. But the new rural community is a voluntary group, it is not determined by common control of the land or by common subjection to a feudal lord as was the village community of the old world; its people are free to come and go where and when they will. The community can compel only through the power of public opinion and its success must depend upon the voluntary loyalty of its people. Thus the strength and the weakness of the community lies in the loyalty of its people. No community can permanently succeed whose people associate in it merely for the advantages which they may gain. There must be a genuine willingness to give as well as to receive, a real desire to do one's share for the common life. Human association cannot succeed on a basis of organized selfishness. The joy of family life arises from the fact that each member is devoted to all and is willing to sacrifice personal interests for the family; without such devotion and sacrifice the true home is impossible. Just because human nature has arisen through long ages of association, man finds no permanent satisfaction in pursuing his own selfish interest; his greatest joy is found in his devotion to others. All human association therefore depends upon loyalty and the higher and more complex the association, the more essential is the loyalty of its members. As Miss Follett has well said, "Loyalty means the consciousness of oneness, the full realization that we succeed or fail, live or die, are saved or damned, together. The only unity or community is one we have made of ourselves, by ourselves, for ourselves."[99]
