This does not mean there can not be a huge difference between the two, there is no sharp dividing line between day and night either but the difference between the two is as big as, well , day and night. > Arithmetic is about me, my consciousness, my body, the matter which seems > to constitute me, all apparent matter, the laws of physics.

Most may agree at the extreme ends of the spectrum just as we agree that a 80 pound man is thin and a 800 pound man is fat, but exactly where a thin man turns into a fat man is a matter of opinion. In the real world nature rarely draws a sharp line between things, she draws a grey blob. > So you do agree with the first person indeterminacy. > I neither agree nor disagree, the concept is not well formed. > as a logician, and in the fundamental matter, it remains important to > understand that we, the comp people, does not know the truth of comp. > I agree, comp can never be proved or disproved so there is no point in worrying about it. I just assume it's true because I could not function otherwise and it gives me time to think about other things; as I said comp isn't everything. > By using the word God, we show respect to our predecessor > But that's another problem, you're giving the word "God" and the people who think the word is sacred far more respect than they deserve. > Unlike Everett QM, we must justifies BOTH the Born rule AND the SWE, > If somebody could derive either of those things starting from nothing but pure numbers and prove that nothing else would be logically consistent it would be the greatest discovery in the history of science, but unfortunately I don't see anything like that happening very soon.
