The Peeved Pedestrian

Solely from what I have read from Fahrenheit 451 I haven't discovered a purpose in the book. I just came back to school and started the book today so I know I'm behind everyone else and their opinions on the story. Although I do know that the inspiration for the book came from Hitler who had burned books around the age that we are now. Also that the Fahrenheit 451 is the temperature that books burn. What I've taken from the book so far is that it seems to be a prediction of how technology may take over.
