(1) One believes that the world is comprised solely of physical things.
(2) One doesn't believe that there are any real natural laws.
What exactly is it that science discovers?
Ideally what there is (and isn't) and for the former, how it "behaves" or what it's like/what its characteristics are, what its "nature" is/how it works, which is also what philosophy ideally does, with science being differentiated by an emphasis on an experimental methodology. What science actually spends far too much time doing, however, is reifying mathematics and doing bad philosophy. (Not that philosophers don't also do a lot of bad philosophy, unfortunately.)
First let me say, that is almost exactly my view of science. I also agree with what you wrote to Janoah, "I can understand why folks believe in it more or less and at least desire for there to be a GUT. I don't think that the notion of real laws of nature really makes sense though, especially because it would require real abstracts that would essentially be akin to platonic universals."
That last point is perhaps most important. The so-called, "natural laws," or, "laws of physics," have been pre-empted and redefined by philosophers and mystics to imply those laws existed first and reality, in some way, is made to conform to the laws, which, as you point out, is akin to platonic universals. And, I might add, shear nonsense.
I also think your simple description of science is not only correct, but profound in its simplicity. All there is for science to study is, "what there is," "how it behaves," "what it is it like," "its characteristics," "its nature," and "how it works."
What a good scientist means by the, "laws of physics," or science are those aspects of, "what is," that have been discovered and correctly describe, "what there is," "how it behaves," "what it is it like," "its characteristics," "its nature," and "how it works," and that those discoveries are correct and every technological success (which depends on those scientific descriptions (laws) of what exists) are a success because reality really has that nature.
The physical world is not what it is because it conforms to some so-called laws of nature, the laws of nature (or physics or science) are only true if they correctly describe what is as it is. Physical laws do not determine what is or how it behaves, they can only describe what is and how it behaves.
[Personally I prefer the term, "scientific principles," to, "laws," because the word, "law," implies something, "enforced," which is exactly what is wrong with the common view of scientific law.]
Does that make sense to you?
