The document provides background information on Aldous Huxley's 1932 novel "Brave New World". It explains that Huxley was concerned about the ways dictators could use science to control people and deny them freedom. He was worried about a future of tyranny and totalitarianism. The title of the novel refers to Miranda's line in Shakespeare's The Tempest about the "brave new world", though Huxley uses it cynically to imply that progress is not always as wonderful as it seems. The novel depicts a dystopian future where people are conditioned and controlled by the state from birth through scientific means like genetic engineering and hypnopaedia (sleep teaching).
