Not only a companion to the Brave New World but it's even a great non-fiction about how our societies gets victimized towards dystopia under psychological techno-dictators. This book explores the concepts of Brave New World, it talks about brain-washing and subliminal injection and how Hitler used these devices in propogandas, also about neo-pavlovian conditioning as applied by commercial brands and religious leaders. It revolves around human-psychology and how herd-corruption takes place.

Amazing thing being, Huxley extrapolated the contents of this entire book just from a single TV interview which he gave being disillusioned about how his fantasy can easily get real soon.
