Granger's group plans on preserving civilization by memorizing books. Through oral tradition, they hope to keep major works alive, pass the information onto their children and hopefully succeeding generations, or until society is willing to hear this. Granger genuinely tells Montag " See how important you've become in the last minute!" emphasizing the importance of books and knowledge that is needed in the world, this is important because the lack of knowledge in Montag’s world was in danger of long-term restriction of reading books for the rest of their lives even if the governor was not there (beauty) unless someone, which in this case, the hobo camps with a library full of memorized books would come in after the war and help restore civilization and the freedom to read without the capital restricting the opportunity to read. Knowledge is useful information. It is information that's adapted to a purpose to create emotion and meaning to the world. Knowledge should not be expected to be perfect. Knowledge is created by imaginative and critical thought. Knowledge for the future helps us think outside the box to be able to communicate logically with one another.
