Think about it. Now on to the androids, which pose their own set of issues regarding the nature of life. Luba, Pris, Roy, and company are so motivated. If you've got to think about how you should respond, then you're in trouble. Dick uses Mercer to present the human need for shared group faith, belief, and community.
Mercer is no god, but rather a sort of touchstone for humankind.
Isidore's character raises delicious questions about the ability to manipulate time, space, and reality. Don't even think about brushing off the importance of this character. And while the Rosen Association is fairly devious, it doesn't take center stage in the book in the same manner. The Rosen Association brings us to the Rachael character who is so attractive in Blade Runner. With her, Dick really sets out some stingers.
