Cosmos: A Personal Voyage (1990 Update), Who Speaks for Earth? [Episode 13]
Context: Since this series' maiden voyage, the impossible has come to pass: Mighty walls that maintained insuperable ideological differences have come tumbling down; deadly enemies have embraced and begun to work together. The imperative to cherish the Earth and protect the global environment that sustains all of us has become widely accepted, and we've begun, finally, the process of reducing the obscene number of weapons of mass destruction. Perhaps we have, after all, decided to choose life. But we still have light years to go to ensure that choice. Even after the summits and the ceremonies and the treaties, there are still some 50,000 nuclear weapons in the world — and it would require the detonation of only a tiny fraction of them to produce a nuclear winter, the predicted global climatic catastrophe that would result from the smoke and the dust lifted into the atmosphere by burning cities and petroleum facilities.
The world scientific community has begun to sound the alarm about the grave dangers posed by depleting the protective ozone shield and by greenhouse warming, and again we're taking some mitigating steps, but again those steps are too small and too slow. The discovery that such a thing as nuclear winter was really possible evolved out of the studies of Martian dust storms. The surface of Mars, fried by ultraviolet light, is also a reminder of why it's important to keep our ozone layer intact. The runaway greenhouse effect on Venus is a valuable reminder that we must take the increasing greenhouse effect on Earth seriously.
Important lessons about our environment have come from spacecraft missions to the planets. By exploring other worlds we safeguard this one. By itself, I think this fact more than justifies the money our species has spent in sending ships to other worlds. It is our fate to live during one of the most perilous and, at the same time, one of the most hopeful chapters in human history.
Our science and our technology have posed us a profound question. Will we learn to use these tools with wisdom and foresight before it's too late? Will we see our species safely through this difficult passage so that our children and grandchildren will continue the great journey of discovery still deeper into the mysteries of the Cosmos? That same rocket and nuclear and computer technology that sends our ships past the farthest known planet can also be used to destroy our global civilization. Exactly the same technology can be used for good and for evil. It is as if there were a God who said to us, “I set before you two ways: You can use your technology to destroy yourselves or to carry you to the planets and the stars. It's up to you.”

Winter, § 24, p. 287; in Conducting Effective Faculty Meetings (2008) by Sue Ellen Brandenburg, p. 12 this appears paraphrased in the form: "Time is money says the proverb, but turn it around and you get a precious truth. Money is time."
The Private Papers of Henry Ryecroft (1903)
Context: Time is money — says the vulgarest saw known to any age or people. Turn it round about, and you get a precious truth —money is time. I think of it on these dark, mist-blinded mornings, as I come down to find a glorious fire crackling and leaping in my study. Suppose I were so poor that I could not afford that heartsome blaze, how different the whole day would be! Have I not lost many and many a day of my life for lack of the material comfort which was necessary to put my mind in tune? Money is time. With money I buy for cheerful use the hours which otherwise would not in any sense be mine; nay, which would make me their miserable bondsman. Money is time, and, heaven be thanked, there needs so little of it for this sort of purchase. He who has overmuch is wont to be as badly off in regard to the true use of money, as he who has not enough. What are we doing all our lives but purchasing, or trying to purchase, time? And most of us, having grasped it with one hand, throw it away with the other.

Could they commend the destructive bolt, as readily as they commend the destructive word, it is hard to say what might happen to the country. They might fulfill their own gloomy prophecies. Of course it is easy to see why certain other classes of men speak hopelessly concerning us. A Government founded upon justice, and recognizing the equal rights of all men; claiming no higher authority for its existence, or sanction for its laws, than nature, reason and the regularly ascertained will of the people; steadily refusing to put its sword and purse in the service of any religious creed or family, is a standing offense to most of the governments of the world, and to some narrow and bigoted people among ourselves.
