It actually is an "artistically licensed" quote from a book title by Hugo Brandt Corstius written under one of his many pseudonyms: Raoul Chapkis. The title of the book is "Zes dagen onbedachtzaamheid kan maken dat men eeuwig schreit" (1966).
If you ask me now what it was all about, I don't remember anymore. But the title stuck in my mind since I've read it.
