Who is the narrator, can she or he read minds, and, more importantly, can we trust her or him?
First-Person (Central Narrator)
This may be the only book you'll ever read mostly narrated in the first-person plural (with "we" instead of "I"). The narrator, Equality 7-2521, never learned how to say "I," because the word was forbidden by his society. In fact, what may be the most important moment in the book happens when the narrator finally switches from "we" to "I" at the start of Chapter 11.
Besides that odd detail, this is a conventional case of first-person narration with a central narrator. It's told to us from the perspective of one character: the main character. And come to think of it, what better technique is there than first-person central narration to tell a story all about the glories of individual self-centeredness?
