Reminds me of Socrates at the Oracle - "I know that I know nothing" - going by memory, I'm almost certainly got it wrong... But close enough.
This was part of how I realized that God must exist. That and him yelling at me, but I still had to be sure I wasn't crazy.
Its impossible to know anything in fullness. Take gravity - we have great equations to describe the behavior of gravity, and we've never found an instance of gravity violating the equations, at least not since Einstein adjusted for relativity. (actually we might have, I'll get to that) But we can still can't claim to know the perfect equation for gravity. There could be some conditions, in magnitude or scale or something else that we haven't seen, where we would need to add some little constant to keep the equation working, and at every scale we've measured the constant would have no effect, but at the right circumstances, like the size of a universe, it makes a difference. Then suppose we make those observations, fix the equation, but there's still something we didn't think of... That would go on forever. So the thing to realize is, gravity is not the gravity equation. The real thing is separate from our description of it. The map is not the territory.
But that's true of everything. Everything you see and touch, is just a representation of the real thing.
The reason scientists think there's dark energy is because the milky way rotates in a way that they can't get out of the gravity equations. So we have evidence of... something. An unknown. Maybe its energy, but it could just be that we don't quite describe gravity in our equations accurately enough.
So, this is what I say in my bio : knowledge approaches the limit of Truth asymptotically. We refine and refine forever, but the real world, the whole Truth of reality, is always beyond us. And not just a little beyond us - infinitely beyond us. In the context of an asymptote approaching its limit, any imperfection is infinite imperfection.
But if we are infinitely away from Truth, then we can say that Truth is infinitely perfect in all things. This may seem like a leap, but I don't think it is. A real thing, as opposed to its symbolic representation, *exists*. I'm being redundant because its honestly like a zen koan. It doesn't make sense to describe a real thing because the real thing describes itself - it is the map and the territory. So a zen teacher points at a duck and says "what's that?" And the student answers, "a duck" and gets whacked for being wrong. The correct answer, although still a symbolic representation, is "quack quack quack!"
Now if the thing is the thing, and it's infinite and enduring, can you subtract one thing off of it and make it less? Nope. Infinity minus one is infinity. Infinity minus an entire personality is infinity. Infinity minus a divinity is infinity. Infinity minus a pantheon of divinities is infinities.
Who are you? I am.
Says everything in the universe.
I got carried away. I hope it was a good read.
