In this paper, we are juxtaposing the notions of cosmopolitanism and koinopolitanism, to sketch a theoretical perspective in which local productions of knowledge, as a binding force of local communities, can meet more abstract regimes of knowing and more global concerns of democratic elites. We see this issue as politically significant in light of the current problems with democracy which we interpreted as resulting, among other factors, form the lack of connections between those regimes of knowing. The crucial part of our argument is that socially engaged art is capable of effectively building such connections, and we analyze community-based artistic interventions by Agnieszka Wolodzko in this perspective.
