Man hatte mir dieses Buch empfohlen, doch ich bin enttäuscht. Und ich habe es nur etwa halb gelesen, weil ich es satt war, alle möglichen Geschichten vom Mann im Mond über Ufos in reicher Auswahl, Verschwörungstherorien, suggestiv induzierte Meinungen etc. in ermüdender Breite dargestellt zu bekommen, um dann zu hören, dass es dafür keinerlei Beweise gibt, oder wie diese Erscheinungen sich erklären. Vielleicht bin ich, weil ich wissenschaftlich ausgebildet bin, einfach der falsche Kunde für dieses Buch. Wenn das Ganze Buch von 450 Seiten auf einen Bruchteil davon komprimiert würde und nur die wirklich wichtigen Dinge gechrieben würden, dann sähe es vielleicht anders aus.

In my opinion this book is the one that better summarizes Sagan's belief that the best approach to reality and all its questions, wonders and challenges are the arduous self-correcting methods of science. If you are expecting it to be written in the most friendly and pleasant way like other books from Sagan, you won't be disappointed.

This book is Carl Sagans' review of part of his life and his passionate love of science, and his plea for a more rational society. However, as per other reviews here, the people most in need of reading this book are precisely the ones who are'nt reading it, and others may read it with a closed mind to begin with. The book is a call for people to think for themselves, using the scientific method, in their everday lives, and give religion (esp. fundamentalists) and many other things, the critical examinations they most desperately deserve. But alas, social inertia is very strong, and the changes envisioned in this book may take a century or longer.
We live in a very credulous age, where healthy skepticism (coupled with a sense of enquiring wonder) is nearly non-existent. I see this all around me and find it very depressing. This volume documents all of this well, and in chapter 12 even supplies tools for a baloney detection kit. Sagan does call for sensitivity and compassion when dealing with peoples' irrational beliefs.
In later chapters, Sagan laments the illiteracy in science and math in this country, a very big problem, and the inability for a large percentage of our population, adults and children alike, to think for themselves, and possible solutions. We should all be concerned about this. Many more issues are discussed by Sagan in the ensuing chapters.
I quote Carl Sagan here (not included in this book). "Extraordinary claims require extraordinary evidence". If more people would understand and believe this, the world would be a more rational and better place. Carl Sagan, my mentor, is dead now, but his works live on to inspire future generations.

Highly relevant topics and beautifully written. Carl Sagan was way ahead of his and our time.
If I had to recommend one book to a friend, it would be the demon-haunted world.

I haven't read all of Sagan's books but out of the ones I have read, this is the one I enjoyed the most. As in his other works, Sagan comes off sounding more like a friend telling a story than an intellectual teaching science. In a very concise manner he deals with many of the nonsensical beliefs that permeate our society, such as alien abductions, the so-called face on Mars, demonology, etc. He even spends a whole chapter using the fantastic invisible dragon analogy which basically states that although you may not be able to disprove my claim that there is an invisible dragon in my garage, this does not prove that it does exist. This is a principle that should be taught in every school in America. Not being able to disprove something, whether it be the existence of Superman, Santa Claus or any one of numerous gods, does not prove that they do indeed exist. What comes through most in this book is Sagan's wonder of nature and cosmology, and his desire that the scientific method be applied to all subjects so that truth may come forward and so that ancient myths and fairy tales can be dispelled. As is evidenced by other reviews on this page, this book will cause some people great discomfort as they find their childhood beliefs obliterated with such clear and concise reasoning. Although it's interesting that Sagan's character gets criticized more so than his actual work, it's not unusual to see such knee jerk reactions occur. I'm often baffled to find that those who attack Sagan on a personal level are the same people who hold murderers like Moses, King David, and the prophet Elisha in high regard.

An emminently successful popularizer even if often a slightly fuzzy and stilted writer and thinker on the cutting edges of science, this book appears to represent something of an explanation of the underpinning philosophies present in much of Carl Sagan's work.
As with so much else that he has written, there are numerous high-points here. Unfortunately, there are also a plethora of low points, including an unwillingness to introduce empirical data and analyses that might make his task (berating "straw men") more formiddable -- and significantly more interesting.
Rather than providing us with a most pursuasive account of views contrary to his own, too often Sagan side-steps the messiness of science to present the enterprise as a unified front. As a rhetorical device, this is a fine mode of addressing "uncritical minds". Ultimately, however, it udnermines much of what he expounds, since a thoroughly critical mind will find much to quibble with and even more to question.
Ironically, Sagan suggests that what we (as "Americans") need to foster is more critical thinking. To have written the book without being willing to engage in the nuanced discussion of criticism against the propositions he makes -- which would be necessary to pursuasively argue many of his key points -- sets the work up for disaster. Applying the tools of critical thinking he proffers to his own work demonstrates two things:
1) These tools *are* useful (presenting them is one of the book's high points),
2) Many assertions and editorial choices in the direction of the book's discourse do not withstand the application of his tools.
To have in one place some basic factual research about where many mistaken notions in what he calls pseudo-science originated (the etymology -- even social history -- of "flying saucer," is one example) is both interesting and useful. Taken as a whole, however, the book falters as often as not.
For a useful contrast, review Gould's "Full House" (a five star book by this writer's estimation). He admits of every scrap of doubt, gives each full and complete airing, and drives his points home much more compellingly.
The difference, in essence, between Sagan and Gould rests in the belief one can infer from each's writings about who their readers are: Gould treats his readers as equals, who are able to critically and exactingly share in the messiness and detailed glory of his subjects. Sagan treats his readers as if they are not yet critical thinkers on the level of the author himself -- and that the readers must be catered to, accordingly.

I have at times felt like a soul brother to Carl Sagan. I, too, am educated in science, and a skeptical and critical thinker - and a non-believer for fifteen years. However, I continue to challenge my assumptions, and I'm left concluding after reading this book that Carl Sagan stopped challenging himself.
The book is an exceedingly rigorous and disciplined application of empiricism and skepticism. Where appropriate, the book is outstanding - in this case, where he debunks UFOs and other paranormal claims. However, I think he is off the mark when he strays into his comments about belief in God. This book is not the final word about faith.
I take issue with Carl on a couple of his assumptions. First, he advocates without real justification that the only way to truth is through skepticism and the scientific method. Yes, science works, and he mentions that it has its limits, but he doesn't seriously consider those limits. Second, I wonder that his perception! of God is too narrow. Sure, skepticism is quite unforgiving of the simple faith of most people, but perhaps the concept may be both bigger and simpler than what he challenges. Is it really appropriate to apply skepticism to the simple question that existence may be about something, may have a grounding that gives us meaning?
I do recommend this book, but with a caveat: if you're really interested in finding truth, consider this book for what it is - an outstanding example of the application of skepticism. Carl Sagan was a wonderful popularizer of science and an uncompromising skeptic, and although clearly well read, he was not a philosopher or theologian. Keep challenging your assumptions - the bigger truths may be revealed to you, but only by reading many more authors.

With The Demon-Haunted World, Carl Sagan delivers a lively and refreshing parry to today's celebration of charlatanism and credulity. Sagan does not just refute silly beliefs, he gives a context for understanding them and appreciating the real mystery and beauty of the world around us. This is not an authoritarian harangue against pseudoscience (no matter how well deserved), for Sagan's approach is not to dismissively lock doors but to throw them open to the light.
This book is especially important for those who are put off by the jargon and technology of science. Like Feynman and Asimov, Sagan was a truly interesting individual who wrote with wit and charm and a fundamental humanity belying the stereotype of scientists as dysfunctional lab drones. He was a scientist whose most lasting contribution is conveying that science is not about facts but about the journey of discovery. Once, a child asked him at a public lecture: "Dr. Sagan, I have a simple question for you: How did the universe begin?" Sagan replied, "I have a simple answer for you: I don't know." Ah, but the joy of finding out - that is Carl Sagan's greatest legacy, and one brightly upheld by this book.

Carl Sagan was one of the few scientists nowadays interested inthe fate of humankind AND communicating science to the common man. Hesaw intelligence and freedom as being intertwined. Sagan was appalled at the amount of pseudoscience in the world today, as characterized by his debunking of alien abductions, New Agers, psychics, and various other false sciences. Although I was disappointed that he did not push non-belief and athiesm more in the book, Sagan did attack blind faith and theology. He was obviously an educated athiest, yet to make it palatable to the masses he did not devote a chapter to the one mythology he should have; religion. Still, Carl does an excellent job at conveying why the numerous pseudosciences are phony in laymen's terms. Anyone from juniour high level, perhaps even before that, to Ph. D's can read this book and still be enthralled by it. The whole book is about one thing: learn to think for yourself. Don't take things unquestioningly and always be skeptical. I am saddened by Sagan's death, yet I believe that this book will carry his ideas to the masses. If we understand what he stood for, he will never truly be gone to us.

The reason why I like Carl Sagan's books is not only due to the fact that he has deep knowledge about the subjects I'm deeply interested in(astronomy and space), he is also one of the few scientists who can write so clearly, stylishly and inspiringly about science. Indeed, who is better qualified than him on such matters as UFO's, alien abductions, supernatural beliefs etc., for he was very much involved in the scientific investigations of such paranormal phenomena. Compared with the number of paranormal literature that exist worldwide, his book presents a refreshing counterbalance to all those spurious claims of the paranormal. However more importantly, his concern for mankind, the frailty of earth, his insights and knowledge on many aspects of life and the Universe, and the sheer breadth and depth of his interests is immediately apparent in this book. To quote Richard Dawkins,"... my candidate for planetary ambassacor can be none other than Carl Sagan himself. He is polymathic, witty, well read, and incapable of composing a dull sentence." I entirely agree. I strongly recommend everyone on earth to read this book.
