Hilde’s mother is a confusing character. She only interacts with Hilde a few times in the text—for the most part, Hilde is too busy reading Sophie’s World to spend time with her mother. Since we know that Sophie’s World is a story written by Albert Knag, Hilde’s father (featuring thinly-veiled versions of Hilde, Hilde’s mother, and Albert himself) it’s unclear what conclusion we’re meant to draw when Sophie accuses her Mom of adultery—is this supposed to reflect Hilde’s insecurity, Albert’s suspicions, or both? While this mystery isn’t resolved, it’s fair to say that Hilde is far closer to her father than her mother, but the reason why is never satisfactorily explained.
The timeline below shows where the character Hilde’s mother appears in Sophie’s World. The colored dots and icons indicate which themes are associated with that appearance.
