It won't work,' Mr. Bentley continued, sipping his tea. 'No matter how hard you try to be what you once were, you can only be what you are here and now. Time hypnotizes. When you're nine, you think you've always been nine years old and will always be. When you're thirty, it seems you've always been balanced there on that bright rim of middle life. And then when you turn seventy, you are always and forever seventy. You're in the present, you're trapped in a young now or an old now, but there is no other now to be seen.
Ray BradburyScience fiction is a great way to pretend you are writing about the future when in reality you are attacking the recent past and the present. You can criticize communists, racists, fascists or any other clear and present danger, and they can't imagine you are writing about them.
