Suddenly the day was gone, night came out from under each tree and spread. - Ray Bradbury

You can't guarantee things like that! After all, when we had all the books we needed, we still insisted on finding the highest cliff to jump off. But we do need a breather. We do need knowledge. And perhaps in a thousand years we might pick smaller cliffs to jump off. The books are to remind us what asses and fools we are.

And then there is that day when all around,
all around you hear the dropping of the apples, one
by one, from the trees. At first it is one here and one there,
and then it is three and then it is four and then nine and
twenty, until the apples plummet like rain, fall like horse hoofs
in the soft, darkening grass, and you are the last apple on the
tree; and you wait for the wind to work you slowly free from
your hold upon the sky, and drop you down and down. Long
before you hit the grass you will have forgotten there ever
was a tree, or other apples, or a summer, or green grass below,
You will fall in darkness...

I don't care what the science fiction trade technicians say, either. They are furious that I get away with murder. I use a scientific idea as a platform to leap into the air and never come back. This keeps them angry at me. They still begrudge my putting an atmosphere on Mars in The Martian Chronicles more than 40 years ago.
