"Fahrenheit 451"

Almost at the end of Fahrenheit 451, Ray Bradbury writes:"There was a damn silly bird, called Phoenix back before Christ: every few hundered years he built a pyre and burned himself up. He must have been first cousin to Man. But every time he burnt himself up he sprang out of the ashes, he got himself born all over again. And it looks like we are doing the same thing, over and over, but we have one damn thing that Phoenix never had. We know the damn silly thing we just did. We know all the damn silly things we've done for a thousand years, and as long as we know that and always have it around where we can see it, some day we'll stop making the goddamn funeral pyres and jumping in the middle of them."
