There is no reason to think that everything that exists can be in principle be knowable to *us*. We have imperfect, fallible, finite minds and finite resources and possibly other physical limitations.
Speak for yourself, you may be as ingnorant as you are today, for the rest of your life, however if you were to live for the next 10k years, you just may know a bit more, than you know today.
However the rest of humanity is unfathamble how much knowledge the human race will gather in the next few hundreds years, let alone the next 10k years. Thus what I say holds water; IF IT EXISTS WE WILL KNOW OF IT.
Just a few thousands years ago, Greeks stipulated of atoms, today we know it to be fact, atoms exist.
I am stipulating that there may be entities outside the realm of what we can *know*. To categorically assert that this cannot be possible is hubris.
This is gibberish, if entities exist with in the realm of our existence is only a matter of time we will know of it. However I doubt that we will find any intellegent entity with the atributes of a subjective god.
Moreover, to suggest it is all either strictly knowable or all strictly unknowable is a fallacy. Like just about everything else, there are shades of grey. There are things we can be certain of. There are things we can be reasonably sure of. And then there are undecidable propositions where we just have to say "I don't know."
Surely, there are things "We don't know YET!!" But in time all things will be known if they exist, that's our nature, to discover it. In the little time that humans have existed we have barely scratched the surface of knowledge, if for example mysticism were irradicated in the times of Plato & Aristotle our knowledge perhaps would have been further advanced than it's today. If we happen to irradicate mysticism i.e. gods, goblins, demons, etc.. within the next decade, our knowledge would quadruple within the next five years after abolishment of silly notions of gods, and demons.
What I'm trying to say here is that mysticism has had a stagnant effect in human epistemology for the past few milleniums.
