(Sorry for disappearing from the thread. I went on vacation for the weekend.)
I think Darth Alran has articulated the point I want to argue against, and also shown where some people are misunderstanding me.
First, to correct the misunderstanding: I don't care about the symbols assigned to math. I think everyone recognizes that they're arbitrary, so there's no point in arguing about that.
What I want to address is the notion of natural processes going on regardless of their awareness. It's easy to miscommunicate what I want to say, so I'll try to be careful:
-I agree with you that the universe would still exist even if humans weren't around to perceive it. (If a tree falls in a forest, it does make a sound--or, at least, the waves in air that a human would perceive as sound.)
-Any true statement that can be made about the universe would be true, even if no one had made the statement. (The "laws of nature" are statements about the universe; they would be true even if no one had made them.)
-A true statement can only be made if the universe is not completely chaotic. (If there we no regularity in anything, words would be useless. "This stone" refers to the fact that a certain set of molecules tend to move around together--it implies a certain regularity about the universe.) Language presupposes an ordered universe.
-Science is a collection of true statements and a method for generating more true statements. (Scientific "facts" and "laws" are true statements; the scientific method and theories are guides that we use in organizing and searching for those statements.)
-Out of the infinity of possible true statements, some are more useful than others. ("On Saturday, 6 June 2009, I weighed exactly 223.78 pounds" vs "I generally weigh about 225 lbs" vs. "The average American male weighs 191 lbs".) Some true statements are more general than others.
-As science advances, it gets more creative in coming up with general & useful true statements. (Aristotle: "Things fall"; Galileo: "Things fall with constant acceleration"; My freshman physics prof: "The equations describing gravitational and electromagnetic attraction have similar mathematical forms."; Salam, Glashow, and Weinberg: "The equations describing the EM and weak forces fit together in this way"; and so on.)
-These useful statements are true, but it can be misleading to think of them as "Truths of Nature".
-A more useful metaphor is this: true statements are tools in a kit, with which we measure and manipulate the universe. Some tools have a much wider range of applications than others.
-The fact that science has come up with some incredibly useful tools tells us only that science has had practice in what it does.
-To say that "those laws of nature existed before we discovered them" is like saying "the possibility of designing a spork existed even before anyone had invented one." (It's also like the Michelangelo quote about the sculpture already being present in the block of marble; he just had to dig it out.) They have a certain aesthetic appeal, but they don't tell us anything useful.
----------------------------------------
-Humans are biologically hardwired to try to invent such tools (both literal tools, and "true statement" tools). It's our biggest evolutionary advantage.
-We receive positive reinforcement for making these tools by feeling pleasure once we've come up with a new one. (Just like we receive positive reinforcement for eating nutritive substances like fats and sugars.)
-Some people are in awe at the usefulness of our scientific tools, and they take that awe as evidence of a greater being (or a greater Truth). That's fine, but from a rational empiricist standpoint, it's illogical. Especially because we can explain that awe in other ways.
Ultimately, awe at the existence of useful and general scientific statements comes down to one of two things:
(1) Awe at the fact that true statements can exist at all. This is nearly (or exactly) the same as awe at the fact that things exist. This viewpoint translates to: "I believe in God because the universe exists."
(2) Awe at the sheer usefulness of some true statements. This amounts to awe at the fact that engineers get better at making tools over time. Since we're the engineers, but we attribute the fact that useful tools can exist to God, this viewpoint strikes me as being unwittingly full of hubris.
