The volume examines the process of globalization from a genealogical point of view. By doing so, it offers a contribution to the understanding of the deep and critical spatial transformation reshaping our world from both a political and a conceptual point of view, taking into consideration recent developments including Brexit and the politics of Donald Trump. Focusing his analysis on the natural element of "air", Vegetti provides an original approach to globalization. Following in the the footsteps of the German jurist and political theorist Carl Schmitt, Vegetti defines our global age as characterized by the transformation of the air into a concrete social space, first through the advent of airplanes, radio waves, and radar and now in the present-day structure of global networks.
