Episode 1: Satsuki's "facts of this world" speech is heavily inspired by George Orwell's most famous novel, Nineteen Eighty-Four. In the novel, the Party's slogan — "War is Peace, "Freedom is Slavery, Ignorance is Strength" — was a paradoxal statement that held hidden truths about the world in the novel - wikia
