Abstract
The article discusses the image of the disruptive entrance of a philosophical stranger into a house related to theatre, as introduced in Plato's Symposium, Bertolt Brecht's dialogues of Der Messingkauf, and Walter Benjamin's essays on Brecht's theater. In each of these cases, the interruption caused by the entrance sets the stage for a performance of philosophy within the arena of theatre. The fact that all three cases are scenes introduced in philosophical texts that address the art of theatre shows how philosophy appropriates the discursive practices of theatre to shed light on the gap between the two disciplines.
