Close Encounters with the Truth
Review of Carl Sagan's: The Demon-Haunted World
Review published in The Times (London) February 1996
by Richard Dawkins
As I close this eloquent and fascinating book, I recall the final chapter title from one of Carl Sagan ’s
earlier works, Cosmos. ‘Who Speaks for Earth?’ is a rhetorical question that expects no particular
answer, but I presume to give it one. My candidate for planetary ambassador, my own nominee to
present our credentials in galactic chancelleries, can be none other than Carl Sagan himself. He is
wise, humane, polymathic, gentle, witty, well-read, and incapable of composing a dull sentence . I
confess to the habit, when reading books, of underlining occasional sentences that I particularly like.
The Demon-Haunted World forced me to desist, simply to save on ink. But how can I not quote
Sagan’s answer to the question why he bothers to work at explaining science?
“Not explaining science seems to me perverse. When you’re in love, you want to tell the world.
This book is a personal statement, reflecting my lifelong love affair with science.”
Buoyant and uplifting though much of the book is, its subtitle is ‘Science as a Candle in the Dark’
and it ends in foreboding. Science – not the facts of science but the scientific method of critical
thought – “may be all that stands between us and the enveloping darkness”. The dark is the dark
of mediaeval and modern witch-hunts, of the pathological dread of nonexistent demons and UFOs,
of humanity’s wanton gullibility in the face of fatcat mystics and the obscurantist gurus of
postmodern metatwaddle. One of Sagan ’s most chilling quotes is a call to arms against science,
from a book published in 1995, which concludes:
“Science itself is irrational or mystical. It’s just another faith or belief system or myth, with no more
justification than any other. It doesn’t matter whether beliefs are true or not, as long as they’re
meaningful to you.”
Truth has its enemies as Sagan documents. But, perhaps because he doesn’t live in Britain, he
overlooks a separate problem faced by science in our culture: a philistine double standard. When
the Daily Telegraph reported a survey finding that a high percentage of adults think the Sun goes
round the Earth, the then Editor inserted, “Doesn’t it? Ed.” One immediately thinks of Bernard
Levin’s preening delight in his own ignorance, or of the patronising snigger with which televi sion
announcers render science stories as the concluding ‘joke’ item at the end of the news. If a survey
found that 50% of adults believe Shakespeare wrote The Iliad, what Editor would find it funny to
insert a parenthetic “Didn’t he? Ed.”? That’s the double standard. Again, when the aggressive
habits of Rottweilers were being excitedly promoted by the news media a while ago, the
responsible government minister went on the radio to reveal the disturbing extent of the problem.
Dogs, she explained patiently, don’t have DNA. Ignorance on such a scale would not be
countenanced in a Minister of the Crown, were the subject anything other than science.
Among the gifts science has to offer is, in Sagan’s words, a baloney detection kit. His book is in
part a manual for using the kit. Here is how to test the credentials of the superhuman
extraterrestrials who annually swarm to Earth in UFOs and abduct humans for sexual experiments
(to the victims’ considerable profit when they sell their stories to the inexhaustibly gullible – or
cynical – press).
“Occasionally, I get a letter from someone who is in ‘contact’ with extraterrestrials. I am invited to
‘ask them anything’. And so over the years I’ve prepared a little list of questions. The
extraterrestrials are very advanced, remember . So I ask things like, ‘Please provide a short proof of
Fermat’s Last Theorem’. Or the Goldbach Conjecture. . . I never get an answer. On the other hand,
if I ask something like ‘Should we be good?’ I almost always get an answer. Anything vague,
especially involving conventional moral judgements, these aliens are extremely happy to respond
to. But on anything specific, where there is a chance to find out if they actually know anything
beyond what most humans know, there is only silence”.
Scientists are sometimes suspected of arrogance. Sagan commends to us by contrast the humility
of the Roman Catholic Church which, as early as 1992, was ready to pardon Galileo and admit
publicly that the Earth does revolve around the Sun. We must hope that this outspoken
magnanimity will not cause offence or ‘hurt’ to “the supreme religious authority of Saudi Arabia,
Sheik Abdel-Aziz Ibn Baaz” who, in 1993, “issued an edict, or fatwa, declaring that the world is flat.
Anyone of the round persuasion does not believe in God and should be punished”. Arrogance?
Scientists are amateurs in arrogance.
Moreover, they have a modicum to be arrogant about : Scientists . . .
“. . . can routinely predict a solar eclipse, to the minute, a millennium in advance. You can go to the
witch doctor to lift the spell that causes your pernicious anaemia, or you can take Vitamin B12. If
you want to save your child from polio, you can pray or you can inoculate. If you’re interested in the
sex of your unborn child, you can consult plumb-bob danglers all you want . . . but they’ll be right,
on average, only one time in two. If you want real accuracy . . . try amniocentesis and sonograms.
Try science.”
I wish I had written The Demon-Haunted World. Having failed to do so, the least I can do is press it
upon my friends. Please read this book.
