After Jacob puts Silver Star down, August talks with him about the reality of the circus. "The whole thing's illusion, Jacob," he says, "and there's nothing wrong with that. It's what people want from us. It's what they expect" (page 104). How does Gruen contrast the worlds of reality and illusion in the novel? Is there anything wrong with pandering to people's need for illusion? Why do we crave the illusions that the circus represents?
