World War Terminus has been and gone, leaving an Earth where radioactive dust keeps the few survivors who haven't emigrated inside for parts of the day; an Earth where real animals are now status symbols; an Earth where renegade androids are 'retired' by bounty hunters.
In the first chapter we meet Rick Deckard, one of these bounty hunters, as he argues with his wife before work about which setting to put their mood organs on. He then tends to his electric sheep and dreams of owning a real animal. Immediately, we are introduced to one of the main themes of this novel: that of reality. In Do Androids Dream of Electric Sheep? Philip K. Dick explores thoroughly the concept of reality - by showing us androids who could almost pass for human if not for a lack of empathy; and a whole business set-up to provide for electric animals; and the theory of Mercerism.
I was struck by the bleak tone, and the fact that Mercerism - a pseudo-religion - is one of the few aspects of life to give people hope, since this could be said to be a false hope. At one point Deckard thinks the following: "This rehearsal will end, the performance will end, the singers will die. Eventually the last score of the music will be destroyed in one way or another, finally the name 'Mozart' will vanish, the dust will have won" and this idea that the world is gradually crumbling shows us why people cling to Mercerism, and the status of owning animals as a way to make it through each day.
