This dissertation takes as its starting point the German composer and director Heiner Goebbels s performative installation Stifters Dinge (2007), seeking to experiment and bring into discussion some impasses related to acts of reading and writing in the present. The research is carried out through an essayistic, fragmentary and indisciplinary perspective - that is, one that is resistant to rigid adherences to disciplines and well-demarcated theoretical critical approaches. On the one hand, the aim of this study is to try to react to the problems of interpretation and representation shaped by the disturbing experience of Stifters Dinge, which is also described by its director as a composition for five pianos with no pianists, a play with nobody acting, and a performance with no performers. On the other hand, it intends to interrogate forms of legibility and valuation in the expanded field of arts today, moving through exploratory and inconclusive paths in a writing supported by the barthesian notion of écriture. In the transit between aesthetics and politics, forms and effects, critical theory and epistemology, the dissertation performs a thorough examination of Stifters Dinge taking into consideration both the performative condition of the theoretical critical activity and some fundamental tensenesses on the relation between language and constitution of knowledge.
