Convivia is a journal that is interested in thinking what architectonics is or could be in the twenty-first century. Pre-specific to architecture, architectonics deals with the real in an abstract, yet edifying manner. Under architectonics, the indeterminacy brought by contemporary science is assumed as a liberation from ontological and epistemological principles, and welcomed as a fortunate occasion to understand and embrace the stating of any principle as an ‘art’ in itself—autonomous, yet not automatic or autarkic. Architectonic deals with the real in terms of a communicational physics, through articulations that are concrete yet reasoned in abstractive and projective manners. The journal aims to set the table for a series of banquets—of convivia—in which courses do not respond to mere needs or inconsequential delights of ‘consumption’. We focus on architectonic alloys of necessities and contingencies: necessities are bounded by contingencies, and contingencies are engendered through ‘figuring out’ what is necessary. Convivia’s interest is to ‘make cases’.
