PLEASE QUOTE FROM THE PUBLISHED VERSION 26 Architecture of radicalized postsecularism Krzysztof Nawratek Introduction Architecture as an academic discipline or a profession is not particularly interested in postsecular thought. There are obviously buildings that were designed for religious functions, but there are very few examples of an interest in postsecularism as a particular way of thinking among architects and architecture theorist (Starkey 2006; Martin 2010), and it should be stressed that in architectural discourse postsecularism relates mostly to spiritualism. One can, however, point out some fundamental questions present in the architectural discourse which overlaps with postsecular thinking. There are at least two issues where architectural and postsecular thinking could meet: one is a spatial context, defined as the unknown or ‘out there’; the other is problem of hierarchies and dependencies. As I will show in this contribution, space is always hierarchical; therefore, one can always describe any spatial configuration as a chain of unequal relationships between dominating and submissive spaces; one can find similar discussions in contemporary postsecular thought. These issues are not, however, in a centre of a mainstream postsecular discourse inspired by Jurgen Habermas’ interventions at the beginning of the twentieth century. There are two main strands of research investigating an issue of religion in urban space. One is influenced by Jurgen Habermas’ intervention in the beginning of the twenty-first century (Habermas 2006, 2008) and focuses on the communication between secular and religious logics
