This piece begins with a selection from chapter ten of Carl Sagan’s book "The Demon-Haunted World" It is followed by some personal thoughts of my own.
Sagan writes,
“A fire-breathing dragon lives in my garage.”
Suppose (I’m following a group therapy approach by the psychologist Richard Franklin) I seriously make such an assertion to you. Surely you’d want to check it out, see for yourself. There have been innumerable stories of dragons over the centuries, but no real evidence. What an opportunity!
“Show me,” you say. I lead you to my garage. You look inside and see a ladder, empty paint cans, an old tricycle—but no dragon.
“Where’s the dragon?” you ask.
“Oh, she’s right here,” I reply, waving vaguely. “I neglected to mention that she’s an invisible dragon.”
You propose spreading flour on the floor of the garage to capture the dragon’s footprints.
“Good idea,” I say, “but this dragon floats in the air.”
Then you’ll use an infrared sensor to detect the invisible fire.
“Good idea, but the invisible fire is also heatless.”
You’ll spray-paint the dragon and make her visible.
“Good idea, except she’s an incorporeal dragon and the paint won’t stick.”
And so on. I counter every physical test you propose with a special explanation of why it won’t work.
Now, what’s the difference between an invisible, incorporeal, floating dragon who spits heatless fire and no dragon at all? If there’s no way to disprove my contention, no conceivable experiment that would count against it, what does it mean to say that my dragon exists? Your inability to invalidate my hypothesis is not at all the same things as proving it true. Claims that cannot be tested, assertions immune to disproof are veridically worthless, whatever value they may have in inspiring us or in exciting our sense of wonder. What I’m asking you to do comes down to believing, in the absence of evidence, on my say-so.
The only thing you’ve really learned from my insistence that there’s a dragon in my garage is that something funny is going on inside my head. You’d wonder, if no physical tests apply, what convinced me. The possibility that it was a dream or a hallucination would certainly enter your mind. But then why am I taking it so seriously? Maybe I need help. At the least, maybe I’ve seriously underestimated human fallibility.
Imagine that, despite none of the tests being successful, you wish to be scrupulously open-minded. So you don’t outright reject the notion that there’s a fire-breathing dragon in my garage. You merely put it on hold. Present evidence is strongly against it, but if a new body of data emerges you’re prepared to examine it and see if it convinces you. Surely it’s unfair of me to be offended at not being believed; or to criticize you for being stodgy and unimaginative—merely because you rendered the Scottish verdict of “not proved.”
Imagine that things had gone otherwise. The dragon is invisible, all right, but footprints are being made in the flour as you watch. Your infrared detector reads off-scale. The spray paint reveals a jagged crest bobbing in the air before you. No matter how skeptical you might have been about the existence of dragons—to say nothing about invisible ones—you must now acknowledge that there’s something here, and that in a preliminary way it’s consistent with an invisible, fire-breathing dragon.
Now another scenario: Suppose it’s not just me. Suppose that several people of your acquaintance, including people who you’re pretty sure don’t know each other, all tell you they have dragons in their garages—but in every case the evidence is maddeningly elusive. All of us admit we’re disturbed at being gripped by so odd a conviction so ill-supported by the physical evidence. None of us is a lunatic. We speculate about what it would mean if invisible dragons were really hiding out in garages all over the world, with us humans just catching on. I’d rather it not be true, I tell you. But maybe all those ancient Europeans and Chinese myths about dragons weren’t myths at all…
Gratifyingly, some dragon-size footprints in the flour are now reported. But they’re never made when a skeptic is looking. An alternative explanation presents itself: On close examination it seems clear that the footprints could have been faked. Another dragon enthusiast shows up with a burnt finger and attributes it to a rare physical manifestation of the dragon’s fiery breath. But again, other possibilities exist. We understand that there are other ways to burn fingers besides the breath of invisible dragons. Such “evidence”—no matter how important the dragon advocates consider it—is far from compelling. Once again, the only sensible approach is tentatively to reject the dragon hypothesis, to be open to future physical data, and to wonder what the cause might be that so many apparently sane and sober people share the same strange delusion."
When examining religious issues such as the existence of God, revelation, visions, miracles and biblical interpretation it is amazing to see how much they have in common with issues such as alien abductions, witchcraft, psychics, channeling past lives and magic. For while the specific claims surrounding these issues vary greatly the believers’ justifications for supporting such odd ideas are all fairly similar. Scientific tests become suspect, contradictions are explained away, questions are side-stepped, logic is bent or disregarded, lack of evidence is ignored and the skeptic’s inability to disprove what the believers themselves have intentionally made irrefutable becomes undeniable proof to the believers of the validity of their insubstantial ideas. And in spite of the skeptic’s reasonable and vigilant approach in examining everyone’s claims in the same fashion it is the skeptic that is viewed as hard headed, arrogant and somehow shallow.
It amazes me how much confidence people place in their own personal experiences while they so quickly reject the experiences of others, unless of course those people’s experiences validates their own perceptions. The evidence the normal person demands when facing wild or odd claims all but disappears once one’s own feelings and pre-existing beliefs become involved. The reality of human fallacy should not count simply against those one already disagrees with it must also be turned inward. Sagan speaks of the large number of women who have reported being impregnated by aliens. These women all had explanations for why they had no alien babies to show or other proof to offer. Many explained that the aliens had come and taken the babies away or that the babies just looked like normal human babies and we couldn’t tell the difference. Presented with these stories most Christians would laugh a little and hardy give them a second thought despite the amazing similarities these stories have to a different story where a woman made odd claims about being impregnated incorporeally, which they believe without question. The same proofs that can be offered for believing in the immaculate conception (personal experiences and a written account) can be offered for believing in these women’s extraterrestrial conception yet one is believed without question and one is quickly rejected for lack of proof. Funny how that works.
Yet despite the scientific failings of all of these groups (alien abductees, psychics, Christians, faith healers, witch doctors, magicians, etc) to prove their assertions it is only the skeptics who remain open to listening to and examining the claims they all make and who are then ready to change their minds if valid evidence presents itself. Most in these groups have made up their minds as to what beliefs to accept without question and what beliefs to reject out of hand but the skeptic does neither. Instead the skeptic conditionally accepts as true that for which the best evidence exists while remaining open to new ideas refusing to reject any without proper examination.
So do I believe in aliens, magic, witches or God? No because as of yet there's no reason to. As Sagan said about his dragon, "what’s the difference between an invisible, incorporeal, floating dragon who spits heatless fire and no dragon at all? If there’s no way to disprove my contention, no conceivable experiment that would count against it, what does it mean to say that my dragon exists? Your inability to invalidate my hypothesis is not at all the same things as proving it true. Claims that cannot be tested, assertions immune to disproof are veridically worthless, whatever value they may have in inspiring us or in exciting our sense of wonder. What I’m asking you to do comes down to believing, in the absence of evidence, on my say-so." So I must ask is God truly anything more than an invisible, incorporeal, floating dragon? Well only based on your say-so, which without further proof is as good as saying no he’s not.
