Dr. Heisenberg: the lights in your car were left on, though we're not sure exactly where you parked.
Dr. Goedel: your order is complete, although we've been unable to prove it.
Dr. Mandelbrot: we've completed measuring for your new suit, even though increasingly minute frames of reference prove that an accurate measurement is impossible.
Mr. Zeno: please come to the lost and found to claim your arrow, which did in fact arrive at its target.
As much as I love infinite regression, we all still have to eat and breathe and walk with no one else's legs but our own, and there's still such a thing as knowing something even when (and perhaps especially when!) endless questions serve to preserve doubt and the notion that we can never really know anything for certain.
But we live in a pragmatic world with an undeniable materialist dimension, and dammit there are just sometimes when you really want a cheeseburger, and when you've got to slam on the brakes because the guy in front of you made an illegal turn, and when it's cold and you need to put on a sweatshirt.
And all the nitpicking, and impossibility of disproving a negative, and the inability to show where every electron is every second, is just superfluous, distracting, and destructive.
That's where I think we're at regarding the theft of the 2004 presidential election.
This is not a post that will attract a lot of comment, but I had to get it out of my system.
