ABSTRACT
Traditionally, an urban community was a city, and the nature of a city was obvious. In a limited space it brought together a wide variety of people; it made them accessible to one another, provided them with communication with the outside world, and stimulated them to engage in many kinds of specialized but interdependent activity. The city had a government whose essential functions were to resolve the people's differences in the common interest and to provide their necessary services. The city was a little world and its tight-knit, articulated form reflected its structural unity.
