“Science fiction writers foresee the inevitable, and although problems and catastrophes may be inevitable, solutions are not.”

“I don't know anything but the simplest rules of English grammar, and I seldom consciously apply them. Nevertheless, I instinctively write correctly and, I like to think, in an interesting fashion. I know when something sounds right and when it doesn't, and I can tell the difference without hesitation, even when writing at breakneck speed. How do I do this? I haven't the faintest idea.”

“There is nothing frightening about an eternal dreamless sleep. Surely it is better than eternal torment in Hell and eternal boredom in Heaven.”

“Writing, to me, is simply thinking through my fingers.”

“It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be...  This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking.”

“Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today, but the core of science fiction -- its essence -- has become crucial to our salvation, if we are to be saved at all.”

“In Hamilton's The Universe Wreckers... it was in that novel that, for the first time, I learned Neptune had a satellite named Triton... It was from The Drums of Tapajos that I first learned there was a Mato Grosso area in the Amazon basin. It was from The Black Star Passes and other stories by John W. Campbell that I first heard of relativity.The pleasure of reading about such things in the dramatic and fascinating form of science fiction gave me a push toward science that was irresistible. It was science fiction that made me want to be a scientist strongly enough to eventually make me one.That is not to say that science fiction stories can be completely trusted as a source of specific knowledge... However, the misguidings of science fiction can be unlearned. Sometimes the unlearning process is not easy, but it is a low price to pay for the gift of fascination over science.”
