It was one thing to have guessed it, another to have had that guess confirmed beyond possibility of refutation.

Those wanderers must have looked on Earth, circling safely in the narrow zone between fire and ice, and must have guessed that it was the favourite of the Sun's children.

The future is not to be forecast, but created.

Few artists thrive in solitude and nothing is more stimulating than the conflict of minds with similar interests.

To be a science fiction writer you must be interested in the future and you must feel that the future will be different and hopefully better than the present. Although I know that most - that many science fiction writings have been anti-utopias. And the reason for that is that it's much easier and more exciting to write about a really nasty future than a - placid, peaceful one.

If children have interests, then education happens.

I don't think there is such a thing as as a real prophet. You can never predict the future. We know why now, of course; chaos theory, which I got very interested in, shows you can never predict the future.
