Is the author not really involved in the action, instead he observes it from outside? But sometimes he slips in Montag’s character?
Bradbury tells this story from a limited third person perspective. The narrator can tell us Montag's thoughts, but no one else's, and the narrator doesn't let us know the future. Ray Bradbury wrote the book to warn people of the dangers of censorship and what comes from an uninformed, non-reading populace. To achieve his goal, he must speak to the reader and most of the time, Bradbury speaks to the reader through the characters of Beatty and Clarisse. In talking through Beatty, he uses a sort of "reverse psychology" in that Beatty tries to convince Montag of the necessity and rightfulness in burning books and in keeping people content. But his arguments serve more to convince the reader of how horrible Beatty's line of thinking is. Whenever Beatty talks to Montag about society, it is Bradbury talking. Clarisse talks about society and how sad the situation is. She laments the fact that people don't really communicate with one another and people don't talk. That's Bradbury talking through her. When Montag begins to understand the problem of his society, then Bradbury begins to speak through him.
