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 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 essay form, Brave New World Revisited (1958), and with his final novel, Island (1962), the utopian counterpart. The novel is often compared to George Orwell's Nineteen Eighty-Four (1949).

In 1999, the Modern Library ranked Brave New World as #5 on its list of the 100 best English-language novels of the 20th century.[2] In 2003, Robert McCrum, writing for The Observer, included Brave New World chronologically at #53 in "the top 100 greatest novels of all time", and the novel was listed at #87 on The Big Read survey by the BBC.
