Brave New World is a novel written in 1931 by Aldous Huxley and published in 1932. Set in London of AD 2540 (632 A.F.—"After Ford"—in the book), the novel anticipates developments in reproductive technology, sleep-learning, psychological manipulation, and classical conditioning that combine profoundly to change society. Huxley answered this book with a reassessment in an essay, Brave New World Revisited (1958), and with Island (1962), his final novel.
