The "dragon hypothesis", in this case, is a metaphor for the existence of a deity: "A fire-breathing dragon lives in my garage."
"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."
I can't say with any certainty that there is no deity, but I can certainly say that there is currently no evidence that would support that hypothesis. Hence "hard agnostic/soft atheist". |
