On page 146 of the 50th Anniversary Simon & Schuster Edition of the novel Fahrenheit 451 is the quote, "We're nothing more than dust jackets for books, of no significance otherwise" (Bradbury 146). This quote takes place in "Part 3" of the novel when Granger is describing the group of homeless intellectuals. Granger explains to Montag that each individual memorizes a specific book in order to preserve the knowledge of the past. Montag learns that the traveling intellectuals developed certain techniques they used to remember entire books to avoid being arrested by the authorities for possessing illegal books. He introduces Montag to several people who have remembered the works of Plato, Marcus Aurelius, and Jonathan Swift. In the future, the group plans on writing down the memorized books so they can re-educate society. Granger tells Montag that the most important thing that the traveling intellectuals have to remember is that they are not important or superior in any way. He then tells Montag that there is nothing significant about them outside of having the ability to memorize books. The specific quote mentioned portrays the groups' humility and selflessness.
