  • We on Earth have just awakened to the great oceans of space and time from which we have emerged. We are the legacy of 15 billion years of cosmic evolution. We have a choice: We can enhance life and come to know the universe that made us, or we can squander our 15 billion-year heritage in meaningless self-destruction. What happens in the first second of the next cosmic year depends on what we do, here and now, with our intelligence and our knowledge of the cosmos.

  • Humans — who enslave, castrate, experiment on, and fillet other animals — have had an understandable penchant for pretending animals do not feel pain. A sharp distinction between humans and 'animals' is essential if we are to bend them to our will, make them work for us, wear them, eat them — without any disquieting tinges of guilt or regret. It is unseemly of us, who often behave so unfeelingly toward other animals, to contend that only humans can suffer. The behavior of other animals renders such pretensions specious. They are just too much like us.

  • When you buy a used car, you kick the tires, you look at the odometer, you open up the hood. If you do not feel yourself an expert in automobile engines, you bring a friend who is. And you do this with something as unimportant as an automobile. But on the issues of the transcendent, of ethics, of morals, of the origins of the world, of the nature of human beings, on those issues should we not insist upon at least equally skeptical scrutiny?

  • Quickly capping 363 oil well fires in a war zone is impossible. The fires would burn out of control until they put themselves out... The resulting soot might well stretch over all of South Asia... It could be carried around the world... [and] the consequences could be dire. Beneath such a pall sunlight would be dimmed, temperatures lowered and droughts more frequent. Spring and summer frosts may be expected... This endangerment of the food supplies... appears to be likely enough that it should affect the war plans.

  • National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national chauvinisms are a little difficult to maintain when we see our planet as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and citadel of the stars.
