An eloquent passage from Don DeLillo's "White Noise" that has inadvertently caught my eye.
"It's like we've been flung back in time. Here we are in the Stone Age, knowing all these great things after centuries of progress but what can we do to make life easier for the Stone Agers? Can we make a refrigerator? Can we even explain how it works? What is electricity? What is light? We experience these things every day of our lives but what good does it do if we find ourselves hurled back in time and we can't even tell people the basic principles much less actually make something that would improve conditions. Name one thing you could make. Could you make a simple wooden match that you could strike on a rock to make a flame? We think we're so great and modern. Moon landings, artificial hearts. But what if you were hurled into a time warp and came face to face with the ancient Greeks. The Greeks invented trigonometry. They did autopsies and dissections. What could you tell an ancient Greek that he couldn't say, 'Big deal.' Could you tell him about the atom? Atom is a Greek word. The Greeks knew that the major events in the universe can't be seen by the eye of man. It's waves, it's rays, it's particles.
"We're doing all right."
"We're sitting in this huge mouldy room. It's like we're flung back."
"We have heat, we have light."
"These are Stone Age things. They had heat and light. They had fire. They rubbed flints together and made sparks. Could you rub flints together? Would you know a flint if you saw one? If a Stone Ager asked you what a nucleotide is, could you tell him? How do we make carbon paper? What is glass? If you came awake tomorrow in the Middle Ages and there was an epidemic raging, what could you do to stop it, knowing what you know about the progress of medicines and diseases? Here it is practically the twenty-first century and you've read hundreds of books and magazines and seen a hundred TV shows about science and medicine. Could you tell those people one little crucial thing that might save a million and a half lives?"
"Boil your water."
"Sure, what about 'washing behind your ears.' That's about as good."
"I still think we're doing fairly well. There was no warning. We have food, we have radios."
"What is a radio? What is the principle of a radio? Go ahead, explain. You're sitting in the middle of this circle of people. They use pebble tools. They eat grubs. Explain a radio."
"There's no mystery. Powerful transmitters send signals. They travel through the air, to be picked up by receivers."
"They travel through the air. What, like birds? Why not tell them magic? They travel through the air in magic waves. What is a nucleotide? You don't know, do you? Yet these are the building blocks of life. What good is knowledge if it just floats in the air? It goes from computer to computer. It changes and grows every second of every day. But nobody actually knows anything."
