Rethinking the "Urban Sociology". Part two: from a need of consistency to an unpredictability hypothesis - I come back to the debate which was begun in the "first part". Now, I focus on the concept of "structure" as a basic moment in the empirical research on the territory (in particular, the concept of perceived structure will be considered). After that, I will stress the connection between science and technology, and the importance to insert them in an Urban Sociology debate (Heidegger and the concept of Ge-Steel). Then, I will conclude putting into evidence the difficulty in territory fruition.
Key words: social morphology, structured territorial context, safety/technology, ontology of decline.
