In “Fahrenheit 451”, Faber, Clarisse, and Granger all share two common bonds – those commonalities are that all three of them disagree with the society in which they live and they all help in getting Guy Montag to see that he needs to revolt against society in order to find his own happiness. Faber and Granger achieve this by allowing Montag to see that books are not the enemy and that he needs to look beyond what he is taught in order to achieve his happiness. Clarisse probably has the greatest impact on Guy Montag in that she is the first person to get him to actually think and to see that he is not happy when he asks him that infamous question, “Are you happy?”
Faber, Clarisse, and Granger are non-conformists. They read books, have read books or are books themselves. They disagree with the social-engineering and mind-numbing effects of the society that cannot or will not read. These three represent free thought and freedom.
The most profound "wake-up" was when Clarisse asked Montag if he was happy. This simple question caused Montag's mind to respond especially after his wife Millie had overdosed on sleeping tablets. Obviously, things were not as they seemed on the surface of the "happy society" in which they lived.
Faber, a former college professor, helps Montag in his quest to destroy the firemen, rebel, and get away. Faber also helps Montag learn better how to read.
Granger the most compliant non-conformist of all explains to Montag that the people in his community "are" the books. They memorize the works and wait until such a time as the current society is overthrown and wisdom and knowledge are put back in their proper place. They break no laws simply because they have no books. But, they have the knowledge that is contained in books stored up in their minds.
They all like to read books.
