I just found the beginning of the text "L'intrus" by Jean-Luc Nancy available online for download as a PDF: This text triggered the film by Claire Denis which we have been watching during the first session http://kit.kein.org/session1

"There must be something of the intrus in the stranger; otherwise, the stranger would lose its strangeness: if he already has the right to enter and remain, if he is awaited and received without any part of him being unexpected or unwelcome, he is no longer the intrus, nor is he any longer the stranger. It is thus neither logically acceptable, nor ethically admissible, to exclude all intrusion in the coming of the stranger, the foreign."
