If it is inexplicable, it should not be claimed as fact.
I'm a little lost here. Where was it claimed that something inexplicable was a fact? I missed that post, but I agree with you. If it can't be explained, then it's not a fact. However, people can have experiences that can't be explained. They have a hard time finding the right words to explain what they felt. Now, that doesn't it mean that whatever or however they interpret their experience is the fact, but it's a fact that they did experience something (whatever it was). Also, take quantum mechanics or dark matter or dark energy. There are many things they can see in nature (like the effects of what they call dark matter) for which
we don't have good explanations or even complete theories or formulas or equations etc, but still, it's a fact that there's something that adds energy to the universe, and there's added gravity in the galaxies, and we don't know why or how. There are several candidates for these WIMPs, and yet, we know there's something for a fact, but we don't know what it is. We can only describe the effects. And the effects are a fact. But it's inexplicable still what is causing them.
It is "daft" to assume something is the case with any kind of certainty, when you can't even understand it enough to explain it to others. Until some kind of explanation can be given, it is best to keep it to ones self.
Some things can only be explained with words that don't really fit. Quantum chromodynamics wasn't chosen because of pretty colors in the quantum world, but because it was convenient way of separating the different properties.
The problem most of the time is rather that each system of thought has its own language. And to understand the system of thought, you have to learn the language that's spoken. Mathematics is one language for science, but not for all of them. Philosophy has its own "language", what specific word means and are used and such. The same for religion. But it also goes for subdivisions in these fields. Ethics has its own set of words. And so does Christianity or mysticism. And I believe that most disagreements comes from misunderstanding each others use of the words. A lot of time I think people agree to the same ideas, just not the same use of words. If Robert.Evans there could describe his views using Christian symbols, concepts, and words, then perhaps you would understand better, but perhaps he can't use them in such a way that's needed? Anyway, that's some of my thoughts on this.
