Ray Bradbury portrays the message that humanity will eventually make the same mistakes and destroy themselves if they’re not taught better through the world of F451. In this world, the knowledge of past mistakes are disposed of through burning books and valuable information. The lack of knowledge just leads them on a cycle of self destruction as they destroy themselves through war and ignorance. Some people in the world are aware of this cycle, and Bradbury shows this through the book people. Granger explains this cycle to Montag and compares it to a Phoenix’s life cycle. He tells Montag, “ We know the damn silly things we’ve done for a thousand years... someday we’ll stop making the goddamn funeral pyres and jumping in the middle of them”
