—Theists believe that the universe possesses this sort of order because there is a rationally orderly God who created the universe.—
So? How is that any more supportable than simply claiming that the universe is consistent and rational (I don’t think anyone seriously can claim that it is, on the whole, orderly)? Indeed, the theist account requires several orders more backstory to it to even get off the ground. It’s not that it’s right or wrong: it’s simply that it doesn’t solve the problem of origins any better (I doubt anything can, formally) than anything else.
Further, the original poster did level a valid criticism at the idea: one cannot have it both ways with an “ordering” god: appeal to a natural regularity based on the idea that god is orderly, and also deny that this order could not, at any time, mean what to us would be a glaring deviation in what we believed up until that point was the natural order. This is generally a problem with all such claims about what a god can and cannot do once it has been established that the god is source of the particular concept in question.
—Classical atheism held the universe holds to the metaphysical view of a universe dominated by chance events and hardly implied an orderly universe.—
I think you are being rather disingenous in talking about “classical atheism,” whatever THAT is, or the “holdings” of non-theists.
You are being remarkably lax about what you mean by “orderly” here. If I take your meaning as best I can, perhaps you are saying that the historical linkage of religion with ordered essentialism provided people with the idea that the universe was easily analyzed for universal traits, and this view tended to push in the direction of more systematized scientific exploration. A case can certainly be made for that, though its worth noting that most of the major scientific revolutions have involved a dismantling of essentialist assumptions.
But I still cannot put my finger on what you mean by setting “chance events” in contrast to “orderly.” You seem to be conflating two different levels of chance and order, as well as confusing intentional order with plain order. Certainly, atheists don’t think that there’s any reason to believe that the order of the universe was intended: but that is hardly the same thing as renouncing the existence of order. Even saying the universe is dominated by chance events (talking on at least a cosmological scale view of the universe as we see it: would you really disagree?) is not the same thing as saying that it is disorderly, or that there are no regularities worth studying. Quite the contrary.
—Perhaps some justification could be made that’s compatible with atheism (I think it can be done), but theism proved to be more conducive to the order in the universe when it came to the birth of modern science.—
I’m not sure there were very many atheists running around at the time in the first place, for which we could get any fair “more” comparison. There weren’t very many Chinese people around for the birth of modern disco either, but that hardly says anything about the ability of the Chinese to do the dance.
—Thus, order in the universe and theism can clearly be quite compatible and perhaps even complementary.—
Indeed, but you could have made this conclusion without a pointless an unjustified dig at atheists, who can have just as little problem positing such a universe. You shouldn’t be talking about “cans” with regard to one extremely vague group and “I can think of some examples of can’ts” with another vague group.
(I also don’t think it’s helpful to say without further explanation that “the universe” is orderly, when it is really only CERTAIN things about it are orderly, which is the whole point)
—There really is no logical principle to tell us that physical laws will hold true in places where we haven’t tested them (even if that place is the future).—
Indeed. But, and I think you’ve missed the crux of this matter if you neglect this point: if they DIDN’T then it would be unintelligible to speak of physical laws. And perhaps it IS unintelligible to speak of them: I agree that we have nothing outside of philosophical assumptions to assure ourselves that it is not. However, if we ever wish to have discussions about this thing we call “truth about the universe” in the first place, then we are going to need to simply grant the axioms that make the concept at least operationally meaningful. The entire enterprise may well be fruitless, but that is simply the chance we take for wanting to ever make such “universal” statements in the first place, and at least we know exactly what we have as opposed to yet another groundless essentialism.
—Most professional scientists do believe they are discovering the truth about nature. For instance, they believe that there really are such things as atoms, DNA, and so forth. They don’t use such theories just because it’s convenient to describe a pattern. They accept them because they believe them to be true. —
This argument relies upon seeing into the minds of others in a way I don’t think is quite fair. It neglects the fact that most real scientists may, and do, have much more sophisticated views on the matter than your account gives your conceptual people credit for. Not only of what they are doing, but what they MEAN by “truth about nature.” They could well have a more constrained operational definition of what they mean by “the truth.”
Personally, I don’t think it’s fruitful to speak about “truth” outside of pure logic unless we have some sort of operational definition of what we mean by it. Far too many discussions of the nature of truth run aground simply because no one thought to define what they mean when they say that something is “true.”
—More to the point though, what are the ultimate foundations of science? First, I think we need to recognize that science has more philosophy integrated into it than some might think.—
Indeed: it’s a whole school of thought unto itself.
—Why is it not a scientific thing to do to reject the five-minute hypothesis as false? Scientists automatically reject this hypothesis when they choose the theory of the universe being much older. It certainly seems to be a very strange thing to have truth not be a relevant factor when the decision is made in choosing scientific theories.—
I think that it could be more a matter of: if the five minute hypothesis is true, then there’s not much more to say about the matter (certainly no scientific evidence can be proffered that does not beg the question). So, while we can’t reall say if it’s true or false, we are still interested in the various things we could discover if it were not the case.
