So I ask that these papers be taken for what they merely are: exercises, trials, tryouts, a means of displaying possibilities, not establishing fact. - Erving Goffman

In recent years there have been elaborate attempts to bring into one framework the concepts and findings derived from three different areas of inquiry: the individual personality, social interaction, and society. I would like to suggest here a simple addition to these inter-disciplinary attempts.

Personal identity, like social identity, divides up the individual's world of others for him. The division is first between the knowing and the unknowing. The knowing are those who have a personal identification of the individual; they need only see him or hear his name to bring this information into play. The unknowing are those for whom the individual constitutes an utter stranger, someone of whom they have begun no personal biography.

I mean this report to serve as a sort of handbook detailing one sociological perspective from which social life can be studied, especially the kind of social life that is organised within the physical confines of a building or plant. A set of features will be described which together form a framework that can be applied to any concrete social establishment, be it domestic, industrial, or commercial.
