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 lost his 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 doesn't notice them escaping into the real world.
