In Fahrenheit 451", how are the books being saved?
In Bradbury's dystopian society where literature is censored and books are considered illegal, there are two ways that intellectuals preserve knowledge and save books. Some individuals like Montag attempt to save books by hiding them in their homes. At the beginning of the novel, Montag hides the books he steals in the ventilator of his home and underneath his pillows. Unfortunately, this way of saving books is dangerous and can easily result in one's arrest. The citizens of Bradbury's dystopian society are required to inform the authorities of anyone they know who possesses illegal books. Eventually, Mildred calls in an alarm on her husband, and Montag is forced to burn his home because he owns several books.
The second way that intellectuals preserve knowledge is by remembering entire books. In Part 3, Montag joins a group of traveling hobo intellectuals who have developed a technique that allows them to remember entire novels. Intellectuals like Granger have books memorized and plan on writing them down after the dystopian society is destroyed. This second way of saving books is less dangerous and cannot be detected by the authorities, because there is no physical copy of the memorized books.
There are two ways that books are being saved in the novel. The first is that people are hiding them in their houses, which is the less effective of the ways. Most of the book is about the consequences of being caught with books in your house. The second way isn't introduced until the end of the novel, but is key in understanding the themes of the novel. Montag joins a group of renegades, most of whom are artists, professors, or philosophers. They have been memorizing the texts of classics books, each taking responsibility for remembering different pieces of literature. They know that a time will come when society will need the words and philosophies from these books, and are preserving them in their minds for that day.
