Read the whole thing. Money quote is at the end.
Let’s go back to 451, which I found myself re-reading recently. It begins with Guy Montag burning a house that contained books. Why? How did it come to be that fireman burned books instead of putting out fires as they always had?
The fireman have been doing it for so long they have no idea. Most of them have never even read a book. Except one fireman—Captain Beatty—who has been around long enough to remember what life was like before. As Montag begins to doubt his profession—going as far as to hide a book in his house—he is subjected to a speech from Beatty. In it Beatty explains that it wasn’t the government that decided that books were a threat. It was his fellow citizens.
