Finally, in the Afterword to Fahrenheit 451, Bradbury clearly expresses his own sensitivity to attempts to restrict his writing.
For example, he feels censored by letters suggesting he should give stronger roles to women or black men.
Bradbury gives the reader a brief description of how society slowly lost interest in books, first condensing them, then relying simply on titles, and finally forgetting about them all together.
Bradbury also alludes to the idea that different "minority" groups were offended by certain types of literature.
Montag finds himself wondering, are they alive or dead?
In truth, in Montag's search for truth and knowledge, he is trying to give true life to his own existence and to prevent the cultural death of society. The old woman burns herself to death, Clarisse is killed by a speeding car, Montag kills Beatty with the flamethrower, and the Mechanical Hound kills an innocent man.
In Fahrenheit 451, owning and reading books is illegal.
Members of society focus only on entertainment, immediate gratification and speeding through life.
Montag learns through the medics that reviving suicide attempts is a very common act.
The commonality of suicide attempts and saves blurs the line between life and death in this futuristic society.
