The postmodern fuzzy universe is confronted with institutionary processes. Personal behaviour is rooted in collective movements. Identity is at the heart of the problematic of the subject, but it also defines itself in relation to social issues. This paper focuses on these various strands, stressing in particular the ethos of subjectivity, which is both an answer to the disintegration of collective identities and the focal resource for their rebuilding. Finally, the idea of sociotopia underlies the attempt to demonstrate the intimately territorial nature of these dynamics.
