Brave New World is a dystopian novel written in 1931 by English author Aldous Huxley, and published in 1932. Largely set in a futuristic World State of genetically modified citizens and an intelligence-based social hierarchy, the novel anticipates huge scientific developments in reproductive technology, sleep-learning, psychological manipulation, and classical conditioning that are combined to make a utopian society that goes challenged only by a single outsider. Huxley followed this book with a reassessment in an essay, Brave New World Revisited (1958), and with Island (1962), his final novel.
In 1999, the Modern Library ranked Brave New World fifth on its list of the 100 best English-language novels of the 20th century. In 2003, Robert McCrum writing for The Observer included Brave New World chronologically at number 53 in "the top 100 greatest novels of all time", and the novel was listed at number 87 on the BBC's survey The Big Read.
