SUMMARY
The article discusses the relationship of tension between fiction and reality in contemporary theater, based on the concept of performative theater and in relation to the philosophy of Vilém Flusser, using examples of recent staging and based on the analysis of renowned researchers. The notions of fiction, reality, intellect, and conversation in Flusser's philosophy are mobilized to suggest that contemporary theater is a kind of differential performative intellect, configuring not a representation but an expansion of reality itself.
