Ours is the first generation that has grown up with science-fiction ideas.

In our time, we have sifted the sands of Mars, we have established a presence there, we have fulfilled a century of dreams!

Life is but a momentary glimpse of the wonder of this astonishing universe, and it is sad to see so many dreaming it away on spiritual fantasy.

I worry that, especially as the Millennium edges nearer, pseudo-science and superstition will seem year by year more tempting, the siren song of unreason more sonorous and attractive.

Books permit us to voyage through time, to tap the wisdom of our ancestors.

Writing is perhaps the greatest of human inventions.

The visions we offer our children shape the future.
