Ray Bardbury’s classic dystopian tale, Fahrenheit 451, is well known as a cautionary tale on censorship and the suppressing of knowledge. It is not his only warning on this danger. In The Martian Chronicles, in the chapter “April 2005 – Usher II,” this scene unfolds:
How could I expect you to know blessed Mr. Poe? …All of his books were burned in the Great Fire…He and Lovecraft and Hawthorne and Ambrose Bierce and all the tales of terror and fantasy and horror and, for that matter, tales of the future were burned. They passed a law. Oh, it started very small…[like] a grain of sand. They began by controlling books of cartoons and then detective books and, of course, films, one way or another, one group or another…there was always a minority afraid of something, and a great majority afraid of the dark, afraid of the future, afraid of the past, afraid of the present, afraid of themselves and shadows of themselves.
These warnings, I think, must be taken seriously. Even now, I read of censorship on certain websites, politicians who openly call for suppression of certain views and venues, repeated attempts to control the internet. People who don’t think the suppression of their rights can occur in our age, need to wake up and listen to what Bradbury wrote decades ago.
It all can begin small. Like a grain of sand.
