Montag turns to Faber in frustration, asking him to teach him how to understand what he reads. Montag is desperate to change his world, realizing that "something's missing."
Faber surprises him by saying that the things he's looking for in society don't necessarily have to be found in books; they could be projected through the "parlor families"—but they aren't. Faber then explains the predominant qualities of literature that reflect what Montag is missing in his vapid and mindless society, which lacks all literature.
First, books provide quality as they examine life. Faber says that they are pores through which readers can touch on common life experiences. Their details are not meant to make readers simply enjoy the experience but instead represent the reality of life, which is sometimes ugly. Faber points out that flowers grow out of "good rain and black loam," meaning that beauty often rises out of pain. Their society doesn't want to face anything that deviates from the "flowers" and "fireworks" of life, so they don't want to investigate the painful ideas which are often found in literature.
Second, books allow readers the leisure to digest the information they contain. Faber points out that in their society, everyone rushes around from one place to the next, and they trust the parlor walls to deliver the truth to them. They don't question it, because the information comes so quickly. Books, on the other hand, provide time to walk away and process information in order to arrive at individual conclusions.
Finally, books often create a need for people to respond based on what they have learned. When people are given quality information and the time to process their thoughts regarding this information, they should have the right to act based on new knowledge.
