The dog saw other dogs looking up in the tree. There are dogs running away with what looks like squirrels in their mouth. The dog smelled a squirrel. The dog saw chewed acorns falling from the branches. The dog sees branches and leaves rustling around. But the dog barks and barks and never sees a squirrel. Is that positive evidence that there is no squirrel in the tree?
Cute analogy, mind if I tweak it to make it a lot more like reality?
Notices a bunch of other dogs looking up at a tree. They are looking very excited, and every so often, one runs off as if he is carrying a squirrel in his mouth, but in fact it looks like his mouth is empty. He sees branches rustling, but then again, it is a windy day. He doesn’t smell anything at all.
Eventually, he asks another dog what is going on (these are very clever dogs), the dogs tell him there are squirrels in the tree, “Just look up there and you’ll see them.”
The dog looks up and up, barks, runs around, but still no squirrels.
“Are you sure?” the dog asks, “I don’t see them.”
“Oh, yes, I’m sure. I’ve had one already.”
“Do you see any right now?”
“Yes! There is one right there, and there, and there, and there! The tree is full of them!”
Still the dog looks and he can’t see a squirrel, and every so often he sees other dogs run off and appear to be eating sticks, wild grass, and a variety of things that look a little, at a big stretch, like squirrels
“I don’t think those are squirrels,” the dog says, “and I really don’t see any squirrels up there.”
“Well, you need to believe they are there before you can see them.”
“Uh… what?”
“You need to have faith in the squirrels. You can’t expect them to just reveal themselves to you. I know in my heart there are squirrels up there, and my life is better for it.”
“Shouldn’t it be pretty easy to see squirrels in a tree full of squirrels? I’ve eaten squirrel before, and they were never this difficult to detect. There were very clear indications that the squirrel was a squirrel.”
“Happy is the dog who believes in the squirrels without seeing.”
“Yeah, I’m going to go bark up another tree.”
“Ugh…you are just pig headed. We all see squirrels. You are so irrational.”
