" The therapist could not budge the patient from her syllogism. She replayed it throughout the hour, 'stuck in a single organization of events.' Seeing it from the other side (from behind the wall, as an observer), I understood the obsessive quality of such an attachment, something comforting in holding on to a smug, all-seeing knowledge, even a sad or hurtful one; something that let the patient control the precise amount of pain she administered to herself.
