Summary
“The Demon-Haunted World” is one of several best-sellers by scientist and science
popularizer Carl Sagan. The theme, which
is never stated clearly in the book, is that science needs to be more present in our
society. Sagan bemoans the reality that pseudoscience is as popular as it’s ever been,
that schoolchildren aren’t given the critical thinking toolbox from which we all can
benefit, and that society at large is woefully ignorant of science — not only of the
available knowledge but of the methods used to derive that knowledge.
What I Liked Least About It
I found several things to dislike about this book, the cumulative effect of which left me with
overall disappointment.
The first thing I noticed was Sagan’s apparent lack of subject organization and difficulty
with transitions. From a reader’s standpoint (I am not a published author), the entire
book seemed like a randomly ordered collection of well-written passages. Entire paragraphs —
sometimes strings of paragraphs — were masterfully constructed, the best words packed into
just the right places, and easily quotable, but then these passages seem to be haphazardly stacked
or spliced in with other well-written passages. Increasingly, I began to picture each well-written
passage on a separate piece of paper, and I imagined the author (or editors) sliding these pieces
of paper around into different orders, shuffling them. I eventually settled on the conclusion that
there must have been the intention, originally, to work up transitional phrases between the
passages, but that this plan was abandoned at some point, for unknown reasons.

The second thing I began to notice was the unusual amount of space given to claims of UFO sightings
and alien abductions. It bugged me because in my memory, the whole “alien abduction”
frenzy peaked in the late 1980s and by the 1990s was long discredited. As I read, I kept wondering
why an eminent scientist like Sagan was spending so much effort debunking these claims that were
already becoming less popular by the time he wrote this book. My memory turned out to be faulty
here; as it turns out, the phenomenon was
peaking
in the 1990s, and I simply didn’t know about it because of how little I watched
TV or kept up with pop culture during that decade. Still, even after I’ve corrected my
memory, it seems as if Sagan devoted far more space to this single topic than he could have,
relative to other pseudoscience topics like astrology, “creation science”, much of
chiropractric claims, “paranormal” claims (which were very popular during that
decade and includes a large range of subjects), folk remedies, homeopathy, magnetic therapy, the
Bermuda Triangle theories, dianetics, ghost sightings, near-death experiences, Nostradamus
“prophecies”, cryptozoology, and so on. Sagan does touch on many of these
topics — not all of them — but spends far more time on UFO sightings and
abduction stories than most of the other topics combined. About halfway through the book, I began
to wonder if I had mistakenly picked up a book meant only to debunk that one set of claims.
A third thing that didn’t show up near the end was that this book was actually
co-authored with Sagan’s wife Ann
Druyan. This wasn’t listed anywhere on the cover, the title page, or the copyright page.
It’s not mentioned on the sales pages of websites that sell the book. The only notifications
are a footnote at the end of the table of contents (with an asterisk denoting which four chapters
were partially or wholly written by Druyan), and then four tiny footnotes later in the book, on the
first page of each of those four chapters. I missed these tiny footnotes until very near the end of
the book as I read the third of these latter chapters and noticed a marked change in style and
the way the topic was treated. Those four chapters were — in my opinion — better
written than the others, but were not in the same style as the rest of the book, so it was
disconcerting as a reader to come across it unaware.
I was also put off a little by the complete lack of citations throughout the book. Sagan often
refers to “a study” or “finding” or “poll” without naming
the study or paper or survey in question, without naming the organization or scientist(s)
responsible for conducting the research, and with no reference point. Yes, there is a list of
references at the back of the book, but none are linked directly to the claims in the text.
While I recognize that he was writing for laity rather than academics, and I know that many
average readers are put off by footnotes or inline references, I still think it would have been
more responsible (especially as a self-identified scientist) to include superscript references
in the text, directly referring readers to specific sources in case they want to further research
the claims.
What I Liked Most About It
Despite the preceding few paragraphs, there is a lot to like about “The Demon-Haunted
World”. As already noted, many passages are well-crafted — poignant, clearly and
concisely articulated, and even powerful at points.
One of the best parts of the book is hidden away in the exact middle — on pages 210-216
of a 434-page book, in the 12th of 25 chapters, and about midway through that chapter. Sagan
calls it a “baloney detection kit”, tools for skeptical thinking. This kit includes
independent confirmation, encourage debate by experts in the field, generate multiple hypotheses
and multiple ways to test them, avoid attachment to your hypothesis, find a way to
quantify/measure, be certain every chain in an argument (including the premise) is solid,
use Occam’s Razor frequently, and make sure hypotheses are falsifiable. He reiterates that
carefully designed and controlled experiments are key, variables must be separated, and
double-blind conditions should be used whenever possible. Immediately afterward, he lists a set
of common logical fallacies with short descriptions of each.
One of Sagan’s subthemes in the book is the question “Whose interest does ignorance
serve?” (page 12). He doesn’t list this with his baloney detection kit, but perhaps he
should have — it’s an excellent question to ask on almost any topic. In political
discussions over environmental regulations, for example, it is helpful to first ask the question:
who profits the most from ignorance on the topic? A very related question is who profits from
rolling back regulations (giant corporations and their shareholders) and who profits from enacting
stricter ones (almost everyone)? Keeping the populace at large in the dark about highly
contentious topics serves the interests of the bad guys — every single time.
Sagan also urges treating anti-science advocates with kindness, noting that “none of us comes
fully equipped”. He points out that “supporters of superstition and pseudoscience
are human beings with real feelings” and that many of them have pure motives, even if they
lack the skeptic’s ability to see through baloney. He advises finding a place of moderation
when it comes to speaking directly against such nonsense. On one hand, if you remain silent in the
face of baloney, then the baloney continues unabated. But if you attack too stringently, too
condescendingly, then you end up severing the human tie between you that was so necessary to
convince them and their followers.
Notable Quotations
I think the following is my favorite quotation from the book. Though the context is about alien
abduction claims, the sentiment can be applied to any claim without hard evidence, and especially
to claims of great importance, such as personal experiences with deities.
“No anecdotal claim — no matter how sincere, no matter how deeply felt, no matter how
exemplary the lives of the attesting citizens — carries much weight on so important a
question... This is not a personal criticism... It is not tantamount to contempt for purported
witnesses. It is not — or should not be — arrogant dismissal of sincere and affecting
testimony. It is merely a reluctant response to human fallibility.”
— pg. 180-1
On the topic of religion:
“It is certainly conceivable that doctrines and ethics that may have worked fairly well in
patriarchal or patristic or medieval times might be thoroughly invalid in the very different
world we inhabit today... Science is forever whispering in our ears, ‘Remember, you’re
very new at this. You might be mistaken. You’ve been wrong before.’ Despite all the
talk of humility, show me something comparable in religion... The fact that so little of the
findings of modern science is prefigured in Scripture to my mind casts further doubt on its
divine inspiration.”
— pg. 34-5
Conclusion
It pains me to say it, but I won’t recommend this book to just anyone, for the reasons listed
above. Others have said this book was eye-opening for them, that it inspired them, that it helped
them climb out of the darkness that is religion. Perhaps that is still true today, for some.
Perhaps if I”d read this book 30 years ago, it would have helped me leave religion sooner and
solidified my critical thinking skills. But as I read it today, in 2017, it is too poorly
constructed overall for my use.
If you’re a fast reader and you have some interest in science, critical thinking, or alien
abductions, you might find this book more worthwhile than I did.
