This paper examines key theoretical perspectives on urbanism and urban space. It begins with Louis Wirth's foundational model of the city as a large, dense, and heterogeneous settlement prone to alienation and social disorder. It then considers Sally Merry's refinement of Wirth's macro-level framework, focusing on boundary tensions at urban peripheries, and Stanley Milgram's small-world theory as a partial refutation of Wirth's alienation thesis. Finally, it explores Robert Rotenberg's concept of metropolitan knowledge as developed in his analysis of Vienna's Naschmarkt, illustrating how urban residents create meaning within city spaces through shared, locally embedded knowledge.
Louis Wirth based his urbanism studies on the city of Chicago, where he lived. In his research, he identified three definable factors of urbanism: large population, dense settlement, and social diversity. A city, in his view, is "a large and permanent settlement, densely inhabited by a heterogeneous population." His model of urbanism describes the typical Western industrial city as dangerous and unhealthy — a place where, due to the sheer scale of urban life, people develop forms of alienation and anarchy and where there is no sense of community.
Sally Merry found that Wirth's model worked best at a macro level, agreeing with his observations about anonymity and disorder. However, she was more preoccupied with how people behave at the city's peripheries. For Merry, boundaries are a source of tension because of the unknown they represent, and she used this insight as the starting point for observing human behavior at the edges of urban space.
