Of course I was again using "existence" in the mathematical sense. Here
I was just saying that you cannot axiomatize any physical theory (rich
enough to explain if only the appearance of observations) without
accepting the independence of truth like "it exists a number such that
Recall once and for all that I don't believe at all (especially by
comp) in any form of substantial numbers or think like that. When I
say that numbers exist, I take it as a mathematical statement, not a
metaphysical one. The metaphysics, or better the theology, relies in
the fact that the comp hypothesis needs an act of faith.
Note that taking a plane or just going out of my bed in the morning
asks some faith too, once comp is assumed (btw).
