This anti-robot novel is oft misunderstood by those who come to it with expectations formed by the pro-robot movie. The novel is essentially a paranoid fantasy about machines which pretend to be people. The pretense is so horrifyingly effective that a bounty hunter engaged in the entirely necessary task of rooting out and destroying these monsters finds that his own humanity has become imperiled.
The novel "DO ANDROIDS DREAM OF ELECTRIC SHEEP?" re-titled "BLADE RUNNER" to tie it to the Ridley Scott film loosely based on it, remains available under either title (and with separate entries on AMAZON), but it is the same book. The film studio wanted to market a "novelization" of the film, but PKD adamantly refused to authorize this, forcing them to instead market his original novel under the film's title. Good move, Phil!
This decision, however, has led to confusion and/or disappointment when readers approach the novel with expectations formed by the film. Many reviewers here (whether they like the book, the film, or both) have commented on how different they are. Few seem to realize, however, the extent that they are in direct and fundamental conflict. Some praise the book for tearing down the distinction between man and machine or promoting other nihilistic views and pro-robot messages that the author would have found abhorrent. Others pan it for lack of focus, or for otherwise failing to promote the film's pro-robot agenda as effectively as the film did.
The book is anti-robot and pro-human, and seeks to uphold the distinction between robot and human, and between illusion and reality, in the face of a most-insidious challenge. The common man is celebrated for his basic decency -- specifically his capacity for basic empathy and compassion -- and the robots are deplored for their complete lack of these qualities. In the book, even a "chickenhead" (a mentally retarded human mutant) is infinitely more valuable than the smartest robot.
The film was pro-robot and anti-human, promoting the idea that a compelling illusion is equivalent to reality. It glorifies the android as a sort of superman ("more human than human") -- stronger, faster, more beautiful, more intelligent, -- who seem poised to inherit the future on a dying Earth. The film even seems to admire the robots for their ruthlessness.
The book makes Deckard (the protagonist) human, and loyal to humans. The film has Deckard switch sides and join the robots. Indeed, in the film (not the book) Deckard may himself be a robot (the latter is never made explicit, but director has made clear it is what he intended). This means that, in the FILM, there are virtually no sympathetic human characters -- those characters who suggest that a man is worth more than a computer program are portrayed as bigots.
In PKD's view, the androids are unquestionably monsters who must be destroyed. The irony, and the central problem posed in the novel, is that their ability to SEEM human (which,, in the NOVEL, is never more than meticulously-programmed fakery), means that those who must destroy robots risk damage to their own humanity in the process. Thus, the author approves of Deckard's wife, whose sympathy for the "poor andys" is evidence of her humanity, while still approving of Deckard's assignment.
In the novel, the robots' increased ability to fool the VK test is merely an advance in programmed mimicry of human test responses. The film, on the other hand, treats the improved performance on the VK test as evidence that the robots are truly "human". But the film's robots do not demonstrate compassion in any meaningful way. The agenda of the film is NOT so mcuh to show that robots are as compassionate as humans, but rather to show that humans are as ruthless as robots (as evidenced, mainly, by their willingness to kill robots). This agenda is eerily similar to that of the TV androids near the end of the novel, who set out to expose human empathy as a myth.
In the novel, the title question must be answered in the negative. Androids DON'T care about other creatures. It is humans who have the capacity care about other creatures -- ironically, even about androids -- even electric sheep.
So many, even among the author's admirers, have missed the novel's true focus that it may be best to defend my interpretation with a quote from the author himself, made shortly before his death (quoted in the book "Future Noir"):
"To me, the replicants are deplorable. They are cruel, they are cold,
they are heartless. They have no empathy, which is how the
Voight-Kampff test catches them out, and don't care about what happens
to other creatures. They are essentially less-than-human entities.
"Ridley, on the other hand, said he regarded them as supermen who
couldn't fly. He said they were smarter, stronger, and had faster
reflexes than humans. 'Golly!' That's all I could think of to reply
to that one. I mean, Ridley's attitude was quite a divergence from my
original point of view, since the theme of my book is that Deckard is
dehumanized through tracking down the androids. When I mentioned
this, Ridley said that he considered it an intellectual idea, and that
he was not interested in making an esoteric film."
