Candles Vs Demons

Among scientists who write Carl Sagan has always struck me as one of the more open minded. Dedicated to the scientific method, he nonetheless admits that there are some things scientists don’t know. The last time I was in Ithaca, therefore, I picked up a copy of his tour de force, The Demon-Haunted World: Science as a Candle in the Dark. I wasn’t really sure what to expect—I’ve been researching demons and I supposed they would be addressed in his book, since they feature in the title. Although that is indeed the case, the book is a collection of essays vindicating in various ways the practice and teaching of science. It is quite a scary book. It was also Sagan’s final book published in his lifetime.

Reading this just after Gabriele Amorth’s An Exorcist Explains Demons, noteworthy for its credulousness, The Demon-Haunted World was like whiplash into reality. Back into the realm of observable facts and testable hypotheses, it was indeed like a candle in the dark. Sagan admits that science can’t speak definitively on the supernatural—something that sets him apart from other science writers—but that doesn’t mean we shouldn’t apply scientific thinking anywhere it’s appropriate. And that includes the universe of politics. Published some two decades before the rise of Trump, the book is surprisingly prophetic when it points to the possibility of the rise of fascism in a nation that distrusts science. Indeed, the book shows Sagan clearly worried that an authoritarian, totalitarian government was on the rise. It’s almost preternatural in its accuracy.

The tome is large enough to dissuade a full summary within the word-limits I set for myself on these daily posts, but I can say that this book is necessary now more than ever. Sagan was a celebrity in his lifetime, a “rock star” scientist. Even so he worried about the deplorable state of science understanding among political leaders he met. For many years America has been mired in conservative causes that distrust science implicitly. Another strain that runs throughout this book is the need for education. Not only has America catered to anti-science groups, it has fallen behind much of the rest of the world in science education. Those who claim to make America great again can’t see that their very tactics have made our nation fall behind the rest of the world when it comes to education, across the board. Surely Sagan was right that a good grounding in scientific thinking is the equivalent of lighting a candle. As for the rest of the country it has been getting darker and darker, and our “leaders” have no idea even how to strike a match.
