The interactions which take place among the members of a community so constituted are immediate and unreflecting. Intercourse is carried on largely within the region of instinct and feeling. Social control arises, for the most part spontaneously, in direct response to personal influences and public sentiment. It is the result of a personal accommodation, rather than the formulation of a rational and abstract principle. _The church, the school, and the family._—In a great city, where the population is unstable, where parents and children are employed out of the house and often in distant parts of the city, where thousands of people live side by side for years without so much as a bowing acquaintance, these intimate relationships of the primary group are weakened and the moral order which rested upon them is gradually dissolved. Under the disintegrating influences of city life most of our traditional institutions, the church, the school, and the family, have been greatly modified. The school, for example, has taken over some of the functions of the family. It is around the public school and its solicitude for the moral and physical welfare of the children that something like a new neighborhood and community spirit tends to get itself organized. The church, on the other hand, which has lost much of its influence since the printed page has so largely taken the place of the pulpit in the interpretation of life, seems at present to be in process of readjustment to the new conditions. It is important that the church, the school, and the family should be studied from the point of view of this readjustment to the conditions of city life. What changes have taken place in recent years in the family sentiments? in the attitudes of husbands toward wives? of wives toward husbands? of children toward parents, etc.? What do the records of the juvenile and morals courts indicate in regard to this matter? In what regions of social life have the mores on the subject of the family life changed most? To what extent have these changes taken place in response to the influences of the city environment? Similarly, investigations might be carried on with reference to the school and the church. Here, too, there is a changed attitude and changed policy in response to a changed environment. This is important because it is, in the last analysis, upon these institutions in which the immediate and vital interests of life find a corporate expression that social organization ultimately rests.
