“People have been making love and having sex in space over the thousands of years that our ancestors lived and traveled in small hunting-and-gathering bands. Earth is in Space.”

Nobel prize lecture (1983)
Context: Words may, through the devotion, the skill, the passion, and the luck of writers prove to be the most powerful thing in the world. They may move men to speak to each other because some of those words somewhere express not just what the writer is thinking but what a huge segment of the world is thinking. They may allow man to speak to man, the man in the street to speak to his fellow until a ripple becomes a tide running through every nation — of commonsense, of simple healthy caution, a tide that rulers and negotiators cannot ignore so that nation does truly speak unto nation. Then there is hope that we may learn to be temperate, provident, taking no more from nature's treasury than is our due. It may be by books, stories, poetry, lectures we who have the ear of mankind can move man a little nearer the perilous safety of a warless and provident world. It cannot be done by the mechanical constructs of overt propaganda. I cannot do it myself, cannot now create stories which would help to make man aware of what he is doing; but there are others who can, many others. There always have been. We need more humanity, more care, more love. There are those who expect a political system to produce that; and others who expect the love to produce the system. My own faith is that the truth of the future lies between the two and we shall behave humanly and a bit humanely, stumbling along, haphazardly generous and gallant, foolishly and meanly wise until the rape of our planet is seen to be the preposterous folly that it is.
For we are a marvel of creation. I think in particular of one of the most extraordinary women, dead now these five hundred years, Juliana of Norwich. She was caught up in the spirit and shown a thing that might lie in the palm of her hand and in the bigness of a nut. She was told it was the world. She was told of the strange and wonderful and awful things that would happen there. At the last, a voice told her that all things should be well and all manner of things should be well and all things should be very well.
Now we, if not in the spirit, have been caught up to see our earth, our mother, Gaia Mater, set like a jewel in space. We have no excuse now for supposing her riches inexhaustible nor the area we have to live on limitless because unbounded. We are the children of that great blue white jewel. Through our mother we are part of the solar system and part through that of the whole universe. In the blazing poetry of the fact we are children of the stars.

Playboy interview (1996)
Context: If NASA's budgeters could be convinced that there are riches on Mars, we would explode overnight to stand on the rim of the Martian abyss. We need space for reasons we have not as yet discovered, and I don't mean Tupperware. … NASA feels it has to justify everything it does in practical terms.
And Tupperware was one of the many practical products that came out of space travel. NASA feels it has got to flimflam you to get you to spend money on space. That's B. S. We don't need that. Space travel is life-enhancing, and anything that's life-enhancing is worth doing. It makes you want to live forever.
