Footprint #28 examines the relation between cybernetics and architecture by focusing on a problem they both share: the production, consumption and flow of information, or, in other terms, of meaning. Therefore, cyberneticisation can set the foundations for a relational account that examines how signs are communicated and how meaning is produced and experienced within systems. This third-order cybernetics extends beyond the original scope of living organisms and their environments in order to include ecologies of ideas, power, institutions, media and so on. In this sense, cyberneticisation is radically environmental, positing the primacy of relations over fixed terms, binary oppositions and linear logics, making it high time for architectural and urban studies to take into consideration its ground-breaking potentials.
