Sophie's World

Sophie's World (Norwegian: Sofies verden) is a 1991 novel by Norwegian writer Jostein Gaarder. It follows Sophie Amundsen, a Norwegian teenager, who is introduced to the history of philosophy as she is asked "Who are you?" "Where does this world come from?" in a letter from an unknown philosopher. The nonfictional content of the book roughly aligns with Bertrand Russell's A History of Western Philosophy.
Sophie's World became a best-seller in Norway and won the Deutscher Jugendliteraturpreis in 1994. The English translation was published in 1995, and the book was reported to be the best-selling book in the world that year. By 2011, the novel had been translated into fifty-nine languages, with over forty million print copies sold. It is one of the most commercially successful Norwegian novels outside Norway, and has been adapted into a film and a PC game.
Sophie Amundsen is a 14-year-old girl who lives in Lillesand, Norway.
The book begins with Sophie receiving two messages in her mailbox and a postcard addressed to Hilde Møller Knag. Afterwards, she receives a packet of papers, part of a course in philosophy.
Sophie, without the knowledge of her mother, becomes the student of an old philosopher, Alberto Knox. Alberto teaches her about the history of philosophy. She gets a substantive and understandable review from the pre-Socratics to Jean-Paul Sartre. In addition to this, Sophie and Alberto receive postcards addressed to a girl named Hilde from a man named Albert Knag. As time passes, Knag begins to hide birthday messages to Hilde in ever more impossible ways, including hiding one inside an unpeeled banana and making Alberto's dog Hermes speak.
Eventually, through the philosophy of George Berkeley, Sophie and Alberto discover that they are actually fictional characters in a book written by Albert Knag as a 15th birthday gift for Hilde, his daughter. They also hypothesize that the "real world" in which their story is being written may itself be fictional. Hilde reads the manuscript, but begins to turn against her father after he continues to meddle with Sophie's life by sending fictional characters like Little Red Riding Hood and Ebenezer Scrooge to talk to her.
Alberto helps Sophie fight back against Knag's control by teaching her everything he knows about philosophy, through the Renaissance, Romanticism, and Existentialism, as well as Darwinism and the ideas of Karl Marx. These take the form of long pages of text, and, later, monologues from Alberto. Alberto manages to concoct a plan so that he and Sophie can finally escape Albert's imagination. The trick is performed on Midsummer's Eve, during a "philosophical garden party" that Sophie and her mother arranged to celebrate Sophie's fifteenth birthday. The party soon descends into chaos as Albert Knag loses control over the world, causing the guests to react with indifference to extraordinary occurrences. Alberto informs everyone that their world is fictional but the guests react with rage, believing him to be instilling dangerous values in the children. When a Mercedes smashes into the garden, Alberto and Sophie use it as an opportunity to escape. Knag is so focused on writing about the car that he does not notice them escaping into his world.
Having finished the book, Hilde decides to help Sophie and Alberto get revenge on her father. Alberto and Sophie can interact only weakly with items in Albert Knag's world and cannot be seen by anyone but other fictional characters. A woman from Grimms' Fairy Tales gives them food before they prepare to witness Knag's return to Lillesand, Hilde's home.
While at the airport, Knag receives notes from Hilde set up at shops and gateways, instructing him on items to buy. He becomes increasingly paranoid as he wonders how Hilde is pulling the trick off. When he arrives back home, Hilde has forgiven him now that he has learned what it is like to have his world interfered with. Alberto and Sophie listen as Knag tells Hilde about one last aspect of philosophy—the universe itself. He tells her about the Big Bang and how everything is made up of the same material, which exploded outward at the beginning of time. Hilde learns that when she looks at the stars she is actually seeing into the past. Sophie makes a last effort to communicate with her by hitting her and Knag with a wrench. Knag feels nothing, but Hilde feels as though a gadfly stung her, and can hear Sophie's whispers. Sophie wishes to ride in the rowboat but Alberto reminds her that, as they are not real people, they cannot manipulate objects. In spite of this, Sophie manages to untie the rowboat and they ride out onto the lake, immortal and invisible to all but a few. Hilde, inspired and mesmerized by philosophy and reconnected with her father, goes out to get the boat back.
The book has been translated into several languages, including Portuguese, Persian, Bengali, English, Hindustani (Hindi, Sindhi and Urdu), French, German, Greek, Chinese, and Kurdish. Below are mentioned the names and translators of the translations.
