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

*Los Angeles Times

"POWERFUL . . . A stirring defense of informed rationality. . . Rich in surprising information and beautiful writing."

*The Washington Post Book World

How can we make intelligent decisions about our increasingly technology-driven lives if we don't understand the difference between the myths of pseudoscience and the testable hypotheses of science? 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.

Casting a wide net through history and culture, Sagan examines and authoritatively debunks such celebrated fallacies of the past as witchcraft, faith healing, 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.

"COMPELLING."

*USA Today

"A clear vision of what good science means and why it makes a difference. . . . A testimonial to the power of science and a warning of the dangers of unrestrained credulity."

*The Sciences

"PASSIONATE."

*San Francisco Examiner-Chronicle

This book challenges the reader to critically scrutinize information professed by supposed experts, and be more of a skeptic. Sagan states early on in the book that "some 95 percent of Americans are scientifically illiterate." By using the scientific method combined with a little bit of logic and common sense, one should find that it is much more difficult to be mentally taken advantage of by pseudoscience "experts." Intelligent inquiry and analysis of information presented, and those presenting it, proves to be an invaluable tool.

Nonetheless, stories regarding crop circles, area 51, and other such nonsense still abound. Sagan runs through various examples and places them under the hypothetical microscope. Once examined more closely, most of these theories and fallacious postulations crumble quite easily. What some people don't realize, and what Sagan points out, is that things just as mysterious and awe-inspiring can be found all around us, and they are indeed factual and are being investigated by those in science fields. We need not look elsewhere to find mysticism and intrigue. People are still trying to completely understand viruses and the molecular building blocks in gas in space, and if people were equally as drawn to understand real phenomena as they are fallacious theories, then more people would be working to unravel the true mysteries that are much more worthy of our efforts.

I truly feel that this is a book everyone should read. Not only does Sagan do an excellent job of attempting to popularize science, but he also tries to teach people how to think for themselves rather than to be force-fed information from less-than-trustworthy sources. The demons in this demon haunted world are both those who perpetuate such celebrated fallacies, as well as those who believe them without question. Sagan attempts to teach, in this book, how to distinguish "real science from the cheap imitation." Indeed, he does just that.

One word: OUTSTANDING.

I read this book over two nights, couldn't put it down, and afterwards was eagerly searching for more of the same. Science at it's best-accurate, timely, well-argued, emotionally and mentally invigorating, spiritually uplifting; and filled with boundless enthusiasm and hope. Like the author, Carl Sagan himself.

This book describes the 'scientific journey'. Alternately curious, cautious, inquiring, uplifting, compassionate, humane, warning, discovering and fulfilling. Topics include UFOs, alien abductions, witches, religion-both good and bad, Roswell, frauds, scientific genuises, skeptical thinking, wishful thinking, deceptive thinking, balanced thinking, belief, superstition, astrology, ESP, myth, and the like; and the role and place of science and scientific inquiry in all of this. For those who think science "destroys" spirituality-does not scientific inquiry with its' abundant curiosity and courageous endeavour accurately describe a spiritual journey to find the truth? Sagan contends, with great clarity and enthusiasm, that it assuredly does. It's just that this scientific journey is not an easy one, neither for the individual, nor humanity, by any means. But when has the attempt to find "truth" and "light" in this complex world of ours, ever been easy? Sagan argues that science and the scientific method is a noble and enlightening endeavour, an unquenchable candle, lit by the human yearning for truth, and able to steer humanity towards truth and goodwill in a world of mists, shadowy truths, and darkness.

For those who wish to open their minds to science and what it has to say about much that goes in this beautiful, yet sometimes dark world of ours, this is the book for you.

This great book (Sagan's last) is a fitting testament to a great man of science. Sagan, who passed away recently, was one of the great communicators of science, and this book is considered by many to be his best.

Reading it was something I'll always cherish.

I realize it doesn't make me a cool guy to gush over a scientist, but I can't help it. I love Carl Sagan! I love Carl Sagan's writings. He has that unique combination of both a brilliant mind and the ability to communicate complicated ideas in a simple, straightforward manner. He can write about complicated scientific topics in a way that conveys the beauty and wonder, but doesn't overwhelm or confuse. He can also write about more humanistic topics, such as abortion, politics, and facing his own death.

In Demon Haunted World, he writes about science, about what science is and what science isn't. Whenever you get in debates with religious types, or with those self-appointed geniuses, the philosophy majors, they will always hit you with the fact that science is just another belief system, just like any religion or philosophy. They will tell you science can't answer all the questions and is often wrong. Of course that is true, if you look at science strictly as a body of knowledge. But that is not what science really is. Science is a process. It is a way of approaching the world, a way of formulating and testing hypotheses. If it is just another belief system, then it is a belief system that grows by virtue of challenging its adherents to challenge and disprove the current state of knowledge. It's the only belief system where you have to be a skeptic to be a zealot.

Debunking myths is part of the fun of this book, but an even important aspect to it is investigating how the human mind works and why we are drawn to myths and magical explanations for things in the first place. After all, I get the thrill of pseudoscience, it's fun stuff to believe. But if presented correctly, the truth can be just as thrilling.

Demon Haunted World should be required reading for any first year college student. It is astonishing how many people get through four or five years of higher education without having developed the ability to think critically.

The lack of critical thinking in this country has real consequences. It is the reason that the anchormen on the national news can't convey a story about a scientific or medical topic in a meaningful way. It's the reason that you meet well-educated parents these days who are more concerned about side effects from vaccinations than about the lethal diseases being vaccinated against. It's the reason that parents believe treating their children's depression is more likely to lead to suicide than leaving it untreated. It's the reason the majority of voters in this country voted to elect a President who openly confesses to having a concrete interpretation of the world. Think about that for a second. We have come to the point where adults fail to recognize that seeing things in black and white, all good versus all evil, is a sign of stunted emotional and intellectual development, not a skill to be bragged about. We live in a time when the media tells us that being balanced means presenting peoples opinions from both sides of the political spectrum, as opposed to challenging the statements from an evidence-based, rational perspective.

I love Carl Sagan, I highly recommend this book, and I highly recommend all of his writings.

In an age where we are surrounded by psychic hotlines and alien abduction stories, the vast majority of the population is consistently fooled into believing the most absurd of notions. As Sagan beautifully demonstrates, this is not because of our collective intelligence, but a part of human nature. _The Demon-Haunted World_ is easily one of the most important books of this century. High school students should read this book to graduate, at least a little exposure to sense will be advantageous to our growing society. Faces on Mars, aliens, faith healers, and various other practitioners of pseudoscience swirl around us in a pool of credulism and blind faith in the most absurd of Golden Calves. Sagan brings the razor of reason to the face of fallacy and superstition and cuts off delusion and myopic belief. There is perhaps no other person who could have exposed this seldom seen part of the human being. Carl Sagan, the man who loved science so much that he felt in his heart the desire to sing it to the rest of the world, deserves the highest recognition for his accomplishments. I can think of no better than to have _The Demon-Haunted World_ shown to the whole of the world.

Many are turned off by science since they find it to be cold, desenchanting or even a bit nihilistic. With a clever sense of humor and easy-to read writting style, Sagan proves that science can be an awe-inspiring spiritual experience, when we are confronted with the immense complexity of nature and our universe. He reminds us how to be a good skeptic: one who is open minded to new information, but will only believe after receiving proof. (Which consists of much more than anecdotal evidence )As Sagan states "I believe that the extraordinary should be pursued. But extraordinary claims require extraordinary evidence." He urges everyone to think skeptically and to express our opinions while being respectfull of others' beliefs. Unfortunately those who would benefit from more skepticism are the ones less likely to pick up this book. It takes courage to abandon the comforts of an "all-loving" ever present god, immortality, and belief in psychic powers in exchange for the truth. However, Sagan shows us how science has greatly improved the quality of life throughout history, and how the systematic search for truth can be more rewarding than blinded-faith. We should be open minded("Absence of evidence is not evidence of absence") without being gullible. And we must remember how "wishfull thinking" does not make something true.
