As someone who almost went to grad school to study 20th-century metaphysics and philosophy of mind, I can't let this go by without comment. Tyler, you've already strayed in this discussion far out of physics per se into philosophy of science, not that there's anything wrong with that! However, the formalist point of view you're advocating (that scientific theories do not describe real entities but rather models consistent with repeatable observation) certainly cannot be generalized in the way you just have without opening the door to an awfully thorny can of metaphysical worms (mixed metaphor very much intentional!). You're glossing over centuries of debate, going back at least to the Enlightenment empiricists (Locke, Hume, Berkeley) in the 17th century, through Wittgenstein in the mid-20th, and beyond. I for one am not at all prepared to abandon wholesale the ontological distinctions among reality, my perceptions of it, and my mental constructs resulting therefrom; I find those distinctions useful, congenial, and well-founded. Many of our perceptions do form patterns to which it is convenient to give names; but let us not confuse the pattern with the thing perceived, lest we put the ontological cart before the horse and begin to think that patterns we have invented out of whole cloth are themselves as real as the perceived ones or the things themselves. For example, I would argue (1) that the computer on which I'm typing this is a real, physical entity; (2) that the computational process going on which puts letters on the screen as I type is not an entity at all, but solely a convenient way to group some of my perceptions (and those of the programmers who wrote the software); and (3) that the numerals on the clock at the bottom of the screen represent real but nonphysical entities, the natural numbers, which (just like the laptop) exist independently of my perception of them---but all three of those assertions are debatable and have been debated by philosophers in recent memory.
