Is it possible that all things are real, but yet some things remain perpetually unknowable? That is, all things may have the same property that known things have: they can (theoretically) be described in a scientific and mathematical sort of way. In other words, I agree with the basic premise of naturalism and materialism and non-mysteriousnessism of all things in their actuality. But with the speed and complexity of the universe as it is, might there be be some high level phenomena that can never be pinned down, no matter how great our intelligence? Some fleeting pattern that cannot be fully apprehended? Isn't this where mysteriousness can legitimately reside?
