Was kümmert mich mein Müll von gestern?

                                     -Albrecht Goetze

“What do I care about my garbage from yesterday?” as described by Elizabeth Wayland Barber in Women’s Work: The First 20,000 Years. 

Each new fact discovered made the picture necessarily look a little different, and he was quite happy to let go of old, outmoded views—the garbage—and move on to a new vision with a joyful laugh of discovery. (299)
