Unfortunately, the interview is only available in German, but I'll translate the passage that seems the most relevant to me:
Since [the death of my father] a lot of things have changed; in fact, they keep changing on an hourly basis. His death was no theatrical production, no artistic image, no discourse. It's no use to keep deluding ourselves. Some things are more real than "we artists" allow them to be.Did you read this? "No discourse" A kindred spirit who believes in reality. Who knows, he might even believe in the biological body!
Thanks Christoph, you made my day!
