The general nature of these changes is indicated by the fact that the growth of cities has been accompanied by the substitution of indirect, "secondary," for direct, face-to-face, "primary" relations in the associations of individuals in the community.
By primary groups I mean those characterized by intimate face-to-face association and co-operation. They are primary in several senses, but chiefly in that they are fundamental in forming the social nature and ideals of the individual. The result of intimate association, psychologically, is a certain fusion of individualities in a common whole, so that one's very self, for many purposes at least, is the common life and purpose of the group. Perhaps the simplest way of describing this wholeness is by saying that it is a "we"; it involves the sort of sympathy and mutual identification for which "we" is the natural expression. One lives in the feeling of the whole and finds the chief aims of his will in that feeling.
Touch and sight, physical contact, are the basis for the first and most elementary human relationships. Mother and child, husband and wife, father and son, master and servant, kinsman and neighbor, minister, physician, and teacher—these are the most intimate and real relationships of life and in the small community they are practically inclusive.
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.
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 probably the breaking down of local attachments and the weakening of the restraints and inhibitions of the primary group, under the influence of the urban environment, which are largely responsible for the increase of vice and crime in great cities. It would be interesting in this connection to determine by investigation how far the increase in crime keeps pace with the increasing mobility of the population. It is from this point of view that we should seek to interpret all those statistics which register the disintegration of the moral order, for example, the statistics of divorce, of truancy, and of crime.
Great cities have always been the melting-pots of races and of cultures. Out of the vivid and subtle interactions of which they have been the centers, there have come the newer breeds and the newer social types. The great cities of the United States, for example, have drawn from the isolation of their native villages great masses of the rural populations of Europe and America. Under the shock of the new contacts the latent energies of these primitive peoples have been released, and the subtler processes of interaction have brought into existence not merely vocational but temperamental types.
