I
suspect, dear copernicus, that there are things the human brain is physiologically incapable of comprehending.
For example, say a person was born without eyes and as such never experienced sight at all. Now, this person could be made to understand what light is in a vague way: It's similar to the warmth he feels from a flame, and he understands people "see" objects from the light that reflects off them the way he "hears" objects from the way sound bounces off them.
But he'll never understand a yerllow shirt with purple polka dots looks horrid when worn with checked pink and lime trousers.
I think the human mind is incapable of wrapping itself around not-Time and non-Space. I think the human mind realizes such things must exist, and can understand
very vaguely just the grossest and most indirect evidence of same, but can not fully comprehend it any more than the eyeless man in the second paragraph could fully comprehend light, much less figure out on his own what a color wheel is, how to make a laser work, vanishing points, optics, etc.
Since not-Time and non-Space clearly exist
independent of the physical (i.e., natural and/or scientific) universe we inhabit, and since from our limited human perspective are the precursors of this universe, there exists something in in the realm of the super-natural/super-scientific that is the prime mover or creator of this universe.
Once the existence of super-nature is established, all sorts of super-nature beings are theoretically possible that could not exist if they were confined to this universe alone. This is
not to say they
must exist, but only that their existence can not be disproven in this physical universe.
There's a book called FLATLAND, a sci-fi novel from the Victorian era (or more properly, a math-fi novel!
) that's available in many places on the Internet as a free e-text. Do a google search and check it out; it's a funny, witty, insightful, and ultimately profound work about two dimensional creatures attempting to comprehend three dimensional creatures.
