“We have not been seeing our Spaceship Earth as an integrally-designed machine which to be persistently successful must be comprehended and serviced in total.”

UN Address (1999)
Context: For how many thousands of years now have we humans been what we insist on calling "civilized?" And yet, in total contradiction, we also persist in the savage belief that we must occasionally, at least, settle our arguments by killing one another.
While we spend much of our time and a great deal of our treasure in preparing for war, we see no comparable effort to establish a lasting peace. Meanwhile, emphasizing the sloth in this regard, those advocates who work for world peace by urging a system of world government are called impractical dreamers. Those impractical dreamers are entitled to ask their critics what is so practical about war.

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.
