The Dragon In My Garage by Carl Sagan

“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, but 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 thing 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 emerge 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 that 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 European 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.

It’s very dear to me, the issue of gay marriage. Or as I like to call it: ‘marriage.’ You know, because I had lunch this afternoon, not gay lunch. I parked my car; I didn’t gay park it.

According to the survey, Macs were cheaper to troubleshoot and required fewer help desk calls; system configuration, user training, and servers/networks/printing were all cheaper for a Mac environment than a PC environment. Software licensing fees turned out to be nearly identical for both platforms.

The real situation is that today, two and a half years after the iPhone debuted, web developers can no longer count on every viewer being able to render Flash. The percentage of web user agents with Flash installed is now going down, not up. My money says that trend is permanent, and further, it’ll reach a tipping point in the not-so-distant future and Flash will turn into something like Internet Explorer.

How would you use flash on an iPad or iPhone though? Anything Flash that requires the keyboard and the mouse at the same time wouldn’t work… Anything that uses arrow keys wouldn’t work… Hovering over controls for drop down menus on flash websites wouldn’t work… Enabling Flash wouldn’t do ***** all but enable ads, why exactly do we want this so bad?

One of the best arguments against flash on the iPhone/iPad yet (apart from the fact that flash is not a web standard, not open source, slow and buggy on the Mac and is fast becoming obselete)

A lot of the people who read a bestselling novel, for example, do not read much other fiction. By contrast, the audience for an obscure novel is largely composed of people who read a lot. That means the least popular books are judged by people who have the highest standards, while the most popular are judged by people who literally do not know any better. An American who read just one book this year was disproportionately likely to have read ‘The Lost Symbol’, by Dan Brown. He almost certainly liked it.

If you had been born in India, I daresay you would be saying the same thing about Lord Krishna and Lord Shiva. If you had been born in Afghanistan, I daresay you would be saying the same thing about Allah. If you would have been born in Viking Norway, you would have been saying the same thing about Wotan. If you would have been born in Olympian Greece you’d be saying the same thing about Zeus and Apollo.

The human mind is extremely susceptible to hallucination.

I absolutely love this quote, and it really sums up religion. How can you be sure that you have the right religion, when religion requires no evidence (only faith)? Surely they are all on a level playing field. You only picked your particular religion because of where you were born. So stop being so sure about it!
