"Brave New World is a dystopian social science fiction novel by English author Aldous Huxley, written in 1931. Largely set in a futuristic World State, whose citizens are environmentally engineered into 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 (1958), and with his final novel, Island (1962). In 1999, the Modern Library ranked Brave New World at number 5 on its list of the 100 best English-language novels of the 20th century."
