Sophie's World

Sophie's World (Norwegian: 'Sofies verden') is a novel by Jostein Gaarder about a Norwegian girl, Sophie Amundsen, who one day starts receiving letters with philosophy lessons from a mysterious stranger. Together they explore the entire history of philosophy, and find out more about who they are themselves. It is a lot less dry than it sounds, thanks to the personality of Sophie and a big twist near the end.

The story is full of mysteries. Who is Alberto Knox, the philosophy teacher? Why would a UN major send his daughter Hilde postcards by way of Sophie, who doesn't know either of them? How do Hilde's scarf and other objects find their way into Sophie's world?

Originally written in Norwegian, Sophie's World has been translated into 54 languages. There is a little known but surprisingly faithful and good movie adaptation made in the late 1990s. A computer game was also based on the novel.

The book is both a mystery novel and a fun philosophy course in itself, so it is heavily recommended as an introduction or refresher to philosophy, for both children (not too young, of course) and adults.

Wild Mass Guessing had it that the book is in fact written by Roald Dahl or written under his command.

Spiritualized's Magnum Opus Ladies and Gentlemen We Are Floating in Space is named after a line from it.

This novel contains the following tropes:

 * Arc Words: "Happy birthday, Hilde!"
 * Conversational Troping: Sophie and Alberto talk about almost all the Philosophy Tropes on the list. They also talk about some Psychology Tropes.
 * Fake Crossover: Late in the story, all kinds of famous fictional characters, including Alice Liddell and Winnie the Pooh, show up for brief cameos. This is, however, after Sophie so it can hardly be said to be canon for any of the other characters.
 * Still, the ending reveals that
 * Framing Device:
 * Gainax Ending: Your head will be spinning.
 * Hand Wave: "A bagatelle, Sophie."

 * Intergenerational Friendship: Sophie and Alberto, eventually.
 * Little Miss Snarker: Sophie.
 * Meaningful Name: Lampshaded with Sophie, Alberto, and Hilde.
 * Medium Awareness: Alberto. He's aware that he and Sophie are, at points even going as far as saying "Next chapter!" and telling Sophie not to talk to him so he can work on his plan while.

 * Mind Screw: The book can drift into this occasionally.
 * Leaning On the Fourth Wall
