Carl Sagan predicted all this. just "sed -s/dragon/Brexit Benefits/"
Suppose (I'm following a group therapy approach by the psychologist Richard Franklin[4]) 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.
How do I do this? The process is comparable to the God of the gaps argument. In this argument, gods are claimed to be responsible for the creation or day-to- day running of aspects of the universe. As scientific knowledge expands, the gods are not found where theists expect them to be. For example, none of our observations of the sun have revealed the presence of Apollo and his chariot.[note 1] Because of this, believers in Apollo's purported role would either have to abandon the belief that he tows the sun around, or redefine parameters of the belief. For example, one could claim that Apollo is invisible to our eyes and instruments.
