Brave New World

Brave New World is a dystopian novel by English author Aldous Huxley, written in 1931 and published in 1932. Largely set in a futuristic World State, inhabited by genetically modified citizens and an intelligence-based social hierarchy, the novel anticipates huge scientific advancements in reproductive technology, sleep-learning, psychological manipulation and classical conditioning that are combined to make a dystopian society which is challenged by only a single individual: the story's protagonist. Huxley followed this book with a reassessment in essay form, Brave New World Revisited , and with his final novel, Island , the utopian counterpart. The novel is often compared to George Orwell's Nineteen Eighty-Four .
