The Demon-Haunted World: Science as a Candle in the Dark

by Carl Sagan

We’ve arranged a global civilization in which most crucial elements—transportation, communications, and all other industries; agriculture, medicine, education, entertainment, protecting the environment; and even the key democratic institution of voting—profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.

One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back. So the old bamboozles tend to persist as the new ones rise. Séances

But censoring knowledge, telling people what they must think, is the aperture to thought police, foolish and incompetent decision-making, and long-term decline.

Tyrants and autocrats have always understood that literacy, learning, books and newspapers are potentially dangerous. They can put independent and even rebellious ideas in the heads of their subjects. The British Royal Governor of the Colony of Virginia wrote in 1671: I thank God there are no free schools nor printing; and I hope we shall not have [them] these [next] hundred years; for learning has brought disobedience, and heresy, and sects into the world, and printing has divulged them and libels against the best government. God keep us from both!
