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

NEW YORK TIMES BESTSELLER • From the renowned astronomer and author of Cosmos comes a “powerful [and] stirring defense of informed rationality” (The Washington Post Book World) in a world where fake news stories and Internet conspiracy theories play to a disaffected American populace.
LOS ANGELES TIMES BOOK PRIZE WINNER • “Glorious . . . A spirited defense of science . . . From the first page to the last, this book is a manifesto for clear thought.”—Los Angeles Times
How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience, New Age thinking, and fundamentalist zealotry and the testable hypotheses of science?
Casting a wide net through history and culture, Pulitzer Prize–winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions. He examines and authoritatively debunks such celebrated fallacies as witchcraft, faith healings, demons, and UFOs. And yet, disturbingly, in today’s so-called information age, pseudoscience is burgeoning, with stories of alien abduction, “channeling” past lives, and communal hallucinations commanding growing attention and respect.
As Sagan demonstrates with lucid eloquence, the siren song of unreason is not just a cultural wrong turn but a dangerous plunge into darkness that threatens our most basic freedoms.

Really thought-provoking work. Sagan's even-handed, open-minded approach to all streams of thought is refreshing and thoroughly engaging. He writes with a truly infectious sense of the beauty inherent in a cogent, thoughtful worldview. I won't bother speaking in a lot of detail about the book, but I will highly recommend it.
This collection of essays was well researched and carefully thought out in the 1990s when they were written. Still pertinent today, perhaps more so, as alternate facts have overtaken our society. Sagan was a brilliant man and I hope that the day for brilliant men to shine has not passed. Much of what he says here speaks to our current cultural obsession with the news or facts or reality that we choose, rather than some reality that exists outside our control, which is testable through scientific methods. I found the final essay the most compelling: "Real patriots ask questions." In it, Sagan deftly argues for the Constitutional separation of church and state, using quote from contemporaries that could have come from today's newsfeed.
"...it's no good to have (Constitutional) rights if they're not used - a right of free speech when no one contradicts the government, freedom of the press when no one is willing to ask the tough questions, a right of assembly when there are no protests, universal suffrage when less than half the electorate votes, separation of church ad state when the wall of separation is not regularly repaired."
