A mathematical theory places limits on how much a physical entity can know about the past, present or future…
David H. Wolpert, a physics-trained computer scientist at the NASA Ames Research Center, has chimed in with his version of a knowledge limit. Because of it, he concludes, the universe lies beyond the grasp of any intellect, no matter how powerful, that could exist within the universe. Specifically, during the past two years, he has been refining a proof that no matter what laws of physics govern a universe, there are inevitably facts about the universe that its inhabitants cannot learn by experiment or predict with a computation…
As Scott Aaronson, a computer scientist at the Massachusetts Institute of Technology, puts it: “That your predictions about the universe are fundamentally constrained by you yourself being part of the universe you’re predicting, always seemed pretty obvious to me…”
What is therefore the point to atheism? Even if there is nothing else but the physical universe, there is no way for any part of it to “learn it all by experiment” or “predict with a computation“. In other words, the physical universe is the only thing that can fully know the physical universe.
How far is that from the definition of Divinity? And what does that leave to the atheist? Absurdities like believing in the non-existence of the physical universe?
If Wolpert is right, there is no logic left in atheism. And Dawkins’ “Ultimate 747” proof of the non-existence of God appears quaint: the Divinity cannot be any part of the physical universe.
One of course can and will always be able to reasonably state agnosticism. But post-Wolpert agnosticism becomes simply the belief that the Divinity cannot be communicated with or experienced as such).
There is one thing we can be certain of, in any case: that there’s more out there than a collection of physical entities.
