This dissertation investigates how knowledges from arts, humanities and Earth sciences have been mobilized by aesthetic experiments, especially scenic and performative, engaged in approaching the existential challenges brought up by the Anthropocene — here interpreted as a direct consequence of an anthropocentric and capitalistic modernity project. The dissertation investigates, therefore, critical and creative proposals that make the scene a counter-scene, that is: experiences that present themselves as radical counterpositions to the ideological premises that underlie modernity and that engender the Anthropocene. These are aesthetic responses that strive, above all, to displace the human from the illusory positions of centrality, sovereignty, omnipotence, self-sufficiency, and independence in relation to the fabric of life. In the final stage of the work, the notions of polyphony, sympoiesis and interspecific compositions are investigated as reflective and formal devices capable of structuring performative proposals that, in form-content, dramaturgy, and staging, establish themselves as counter-scenes to the Anthropocene and anthropocentrism. From works like Stifter s dinge, by Heiner Goebbels, we can glimpse forms of scenic experience in which the human ceases to be represented as the only and indispensable protagonist of the scene of life — of the Earth as well as of Theater.
