“Recurrent Institutions” addresses how agonistic assemblages are not antithetical to taking institutional form, of a kind. I do so by showing that the morphology of dividual direct action is amenable to certain forms of institutional configurations that can augment efforts to make more recurrent, if not perduring, worldly spaces for the free appearance of plurality without sacrificing the contingency and freedom vital to agonistic democratic participation. Here, I examine the example of Critical Mass bicycle rides, which have become a global phenomenon in part by virtue of occurring at rush hour on the last Friday of every month, through Giorgio Agamben’s concepts of “destituent power,” “inoperativity,” and “use.” I argue that Critical Mass stages an agonistic enactment of destituent power that is predicated on the festively performative repurposing of commercial thoroughfares as common spaces, public goods, that, on the fly, renders them momentarily inoperative. This tactic blends the recurrence of occurring on the final Friday of every month with the spontaneity of an ever-different route that is decided upon democratically by an open and rotating cast of participants to mobilize the demobilization of ecologically catastrophic capitalist flows. Riders build trust in a world of democratic agonism as they also build capacity as democratic citizens.
