During the course of Sophie’s World, Hilde Møller Knag reads from a binder her father, Albert Knag, has sent her. In this binder, there’s a book called Sophie’s World, which corresponds pretty closely to the book we, the readers, are reading. By setting part of its action within a book, Sophie’s World—that is, the book we’re reading—brings up questions of what is and isn’t real, and whether a work of fiction can’t take on a kind of philosophical truth or reality that transcends its artificiality. In this way, the binder symbolizes the ambiguous nature of reality, the very thing that compels philosophers to use both reason and observation to understand the world.
