The thesis discusses concepts of ‘concealment’ and ‘unconcealment’ to explore how business-as-usual politics offers an inadequate stage for environmental group Extinction Rebellion’s urgent demands. Jürgen Habermas’ theory of the public sphere is taken as an instance of such inadequacy. Jacques Rancière’s critique of Habermas illustrates potential concealments within the politics of consensus. I seek to establish connections, not ordinarily made, between Martin Heidegger, Jacques Rancière, and Bertolt Brecht. I argue that each theorist offers a potential ‘unconcealment’ for Extinction Rebellion. The objective of this thesis is to evaluate these unconcealments as a means for understanding and assessing the action of Extinction Rebellion in responding to the climate emergency. The motif of the stage acts as a common thread throughout.
