About the book:
Do Androids Dream of Electric Sheep? (retitled Blade Runner: Do Androids Dream of Electric Sheep? in some later printings) is a science fiction novel by American writer Philip K. Dick. First published in 1968, the novel is set in a post-apocalyptic San Francisco, where Earth’s life has been greatly damaged by nuclear global war. Most animal species are endangered or extinct from extreme radiation poisoning, so that owning an animal is now a sign of status and empathy, an attitude encouraged towards animals. The book served as the primary basis for the 1982 film Blade Runner.
The main plot follows Rick Deckard, a bounty hunter who is faced with killing (“retiring”) six escaped Nexus-6 model androids, while a secondary plot follows John Isidore, a man of sub-par IQ who aids the fugitive androids. In connection with Deckard’s mission, the novel explores the issue of what it is to be human. Unlike humans, the androids are claimed to possess no sense of empathy.
