As the living increasingly emerges as the conceptual horizon of urban production, philosopher Chris Younès analyses the dynamics of an architecture of environments. Whether biotope or architecture, environments are the product of the interactions that constitute them and continuously transform them. Considering environments in this way allows us to emphasize “the in-between,” with every metabolism being both self-organized and porous, operating within a system of relationships. In this way, it insists upon the fecundity of the “reliances” that exist between city and nature as the condition for a symbolic reestablishment of urban environments through an increased coexistence with nature. Developing urban environments’ capacities for resilience requires that we no longer step outside of our environment, as modern thinking would encourage, but rather drives us to understand and establish alliances with the environment, with the goal of revealing, managing, and revitalizing it. In this way, we will see the reemergence of new ways of thinking and doing, in order to “renature” both architecture and the city.
