Conflict groups, like sects and parties, and accommodation groups like castes and classes depend for survival upon isolation. Free intercourse of opposing parties is always a menace to their morale. Fraternization between soldiers of contending armies, or between ministers of rival denominations is fraught with peril to the fighting efficiency of the organizations they represent. The solidarity of the group, like the integrity of the individual, implies a measure at least of isolation from other groups and persons as a necessary condition of its existence.
The life-history of any group when analyzed is found to incorporate within it elements of isolation as well as of social contact. Membership in a group makes for increasing contacts within the circle of participants, but decreasing contacts with persons without. Isolation is for this reason a factor in the preservation of individuality and unity. The esprit de corps and morale of the group is in large part maintained by the fixation of attention upon certain collective representations to the exclusion of others. The memories and sentiments of the members have their source in common experiences of the past from which non-members are isolated. This natural tendency toward exclusive experiences is often reinforced by conscious emphasis upon secrecy. Primitive and modern secret societies, sororities, and fraternities have been organized around the principle of isolation. Secrecy in a society, like reserve in an individual, protects it from a disintegrating publicity. The family has its "skeleton in the closet," social groups avoid the public "washing of dirty linen"; the community banishes from consciousness, if it can, its slums, and parades its parks and boulevards. Every individual who has any personality at all maintains some region of privacy.
A morphological survey of group formation in any society discloses the fact that there are lateral as well as vertical divisions in the social structure. Groups are arranged in strata of relative superiority and inferiority. In a stratified society the separation into castes is rigid and quite unalterable. In a free society competition tends to destroy classes and castes. New devices come into use to keep aspiring and insurgent individuals and groups at the proper social level. If "familiarity breeds contempt" respect may be secured by reserve. In the army the prestige of the officer is largely a matter of "distance." The "divinity that doth hedge the king" is due in large part to the hedge of ceremonial separating him from his subjects. Condescension and pity, while they denote external contact, involve an assumption of spiritual eminence not to be found in consensus and sympathy. As protection against the penetration of the inner precincts of personality and the group individuality, there are the defenses of suspicion and aversion, of reticence and reserve, designed to insure the proper social distance.
3. Classification of the Materials
The materials in the present chapter are intended to illustrate the fact that individuality of the person and of the group is both an effect of and a cause of isolation.
The first selections under the heading "Isolation and Personal Individuality" bring out the point that the function of isolation in personal development lies not so much in sheer physical separation from other persons as in freedom from the control of external social contacts. Thus Rousseau constructs an ideal society in the solitude of his forest retreat. The lonely child enjoys the companionship of his imaginary comrade. George Eliot aspires to join the choir invisible. The mystic seeks communion with divinity.
This form of isolation within the realm of social contacts is known as privacy. Indeed privacy may be defined as withdrawal from the group, with, at the same time, ready access to it. It is in solitude that the creative mind organizes the materials appropriated from the group in order to make novel and fruitful innovations. Privacy affords opportunity for the individual to reflect, to anticipate, to recast, and to originate. Practical recognition of the human demand for privacy has been realized in the study of the minister, the office of the business man, and the den of the boy. Monasteries and universities are institutions providing leisure and withdrawal from the world as the basis for personal development and preparation for life's work. Other values of privacy are related to the growth of self-consciousness, self-respect, and personal ideals of conduct.
Many forms of isolation, unlike privacy, prevent access to stimulating social contact. Selections under the heading "Isolation and Retardation" indicate conditions responsible for the arrest of mental and personal growth.
The cases of feral men, in the absence of contradictory evidence, seem adequate in support of Aristotle's point that social contacts are indispensable for human development. The story by Helen Keller, the talented and celebrated blind deaf-mute, of her emergence from the imprisonment of sense deprivation into the free life of communication is a most significant sociological document. With all of us the change from the animal-like isolation of the child at birth to personal participation in the fullest human life is gradual. In Helen Keller's case the transformation of months was telescoped into minutes. The "miracle" of communication when sociologically analyzed seems to consist in the transition from the experience of sensations and sense perceptions which man shares in common with animals to the development of ideas and self-consciousness which are the unique attributes of human beings.
The remaining selections upon isolation and retardation illustrate the different types of situations in which isolation makes for retardation and retardation in turn emphasizes the isolation. The reversion of a man of scientific training in the solitudes of Patagonia to the animal level of mentality suggests that the low intelligence of the savage, the peasant, and the backward races is probably due more to the absence of stimulating contacts than to original mental inferiority. So the individuality and conservatism of the farmer, his failure to keep pace with the inhabitant of the town and city, Galpin assigns to deficiency in social contacts. Then, too, the subtler forms of handicap in personal development and achievement result from social types of isolation, as race prejudice, the sheltered life of woman, exclusiveness of social classes, and make for increased isolation.
