It follows from what is said that an individual may have many "selves" according to the groups to which he belongs and the extent to which each of these groups is isolated from the others. It is true, also, that the individual is influenced in differing degrees and in a specific manner, by the different types of group of which he is a member. This indicates the manner in which the personality of the individual may be studied sociologically.
Every individual comes into the world in possession of certain characteristic and relatively fixed behavior patterns which we call instincts. This is his racial inheritance which he shares with all members of the species. He comes into the world, also, endowed with certain undefined capacities for learning other forms of behavior, capacities which vary greatly in different individuals. These individual differences and the instincts are what is called original nature.[52]
Sociology is interested in "original nature" in so far as it supplies the raw materials out of which individual personalities and the social order are created. Both society and the persons who compose society are the products of social processes working in and through the materials which each new generation of men contributes to it.
Charles Cooley, who was the first to make the important distinction between primary and secondary groups, has pointed out that the intimate, face-to-face associations of primary groups, i.e., the family, the neighborhood, and the village community, are fundamental in forming the social nature and ideals of the individual.[53]
There is, however, an area of life in which the associations are more intimate than those of the primary group as that group is ordinarily conceived. Such are the relations between mother and child, particularly in the period of infancy, and the relations between men and women under the influence of the sexual instinct. These are the associations in which the most lasting affections and the most violent antipathies are formed. We may describe it as the area of touch relationships.
Finally, there is the area of secondary contacts, in which relationships are relatively impersonal, formal, and conventional. It is in this region of social life that the individual gains, at the same time, a personal freedom and an opportunity for distinction that is denied him in the primary group.
