but at the end of the day we use scientific knowledge because it works. Hot damn! Here's what I wrote 10 months ago:

Nazis? You lose. Pfft. I didn't write it... xkcd did. I just thought it mirrored you fairly well. Regardless, y'all should click that link... that fucker's spot-on hilarious.

I would say that we accept our successful theories (i.e. the ones that make accurate and reliable predictions) as being accurate (but probably imperfect) descriptions and models of physical reality. Better approximations to reality than those theories or explanations which don't "work". Yes, a lot of people would say that. We have the colloquial phrase "its been scientifically proven" that means that since there's a scientific explanation that works, then that's correct explanation. But that's not something that comes from the science, itself.
Well why do they "work" more successfully than the alternatives unless they are more accurate descriptions of reality than the alternatives? More "correct" than the alternatives, if you will. There's multiple reasons. Part of it is how the theory is set-up (rigorous and parsimonious), how simple the falsification test would be, and what you're testing it on. For example, Newtonian Physics works great sometimes, but that doesn't mean it it is more correct than quantum mechanics. But its easier to measure the position of a falling ball, and see that the numbers fit within the simple newtonian equations, than it is to test quantum mechanics. So we'd expect some people to think that newtonian mechanics are more correct, and also to think that quantum mechanics has more problems. And we do see that from the less scientifically inclined people because they think "working" = "correct" and its a lot easier to see newtonian mechanics "work".

That Newtonian mechanics is easier to apply than QM or GR is not in doubt. But since when did ease of use have anything to do with how correct or incorrect a theory is? Ease of use, and being easily seen to work, is what suggests to people a sense of correctness. A sense of correctness doesn't come from the science, itself.
When (for example) evolutionary theory says that humans and chimps share a common ancestor is this a statement about "what works" or are we actually saying (albeit tentatively) that this actually physically occurred? The Theory of Evolution (RM+NS), itself, doesn't say that humans and chimps share a common ancestor. That is something we can deduce from assuming the theory is correct, and yes, that is a statement of actually occurrance. When we're testing the theory, we're finding that RM+NS works as an explanation. As long as it keeps working, we'll continue to use it. If we find that it doesn't work somewhere, then we'll add to or modify it. Injecting a sense of correctness is unneccessary.
I don’t see how you can separate what works from some notion of what is correct in the sense or being an accurate representation of reality. Sometimes Newtonian Mechanics work better, but that doesn't mean they're more correct.
If our scientific knowledge isn’t knowledge of reality what is it knowledge of? I'm not saying it is knoweldge of something else.
If our scientific theories are not theories about reality itself why do some theories yield more accurate and reliable predictions regarding the behaviour of reality than others? Answered in Message 160:
quote: If we're measure the position of a falling ball, its easier to get Newtonian Mechanics to work and "yield more accurate and reliable predictions". But we wouldn't say that it is more "correct" or more "about reality". Saying that is just unneccessary. You can say that if you want to, but its not something comming from the science, itself.
But I am not asking less scientifically inclined people. I am asking you. The point was that a lot of people inject a sense of correctness into scientific explanations that work and that that isn't something that comes fromt he science, itself.

I have no idea what you are talking about "unnecessary" for. If you want to just want to use scientific theories to predict things (e.g. in an engineering sense) then you can certainly just do that and not worry about anything else. That's what I'm saying, and that that is the protocol. There's no reason, from a scientific persepective, to talk about the correctness or reality-ness.
But if you want to ask the question as to why some theories yield more accurate and reliable results than others you inevitably have to confront the idea that some theories are better descriptions of reality (i.e. more correct) than others. That question is outside the scope of science, i.e. it is not something science can answer about itself. You're into philosophy at that point.

How can that be the "protocol" when scientific theories are seeking to provide explanation and understanding rather than just predictions for engineers? Well, I do tend to think in terms of Applied Science.... I suppose there could be some Theoretical Scientists out there who think of their theories in terms of correct-ness and reality-ness... but that's thier problem
If you want to construct a theory that accurately describes reality then of course there is. How could there not be? But that was my point, that scientists don't give a shit about how accurately they're "describing reality" as long as the theory is working. But then again, I'm thinking about the application here, not some musings outside of the lab.
CS writes: You're into philosophy at that point. So what? I have work to do in the lab... Have fun musing about how much correctness you've attained. ABE: If you want to talk about correct-ness and reality-ness of scientific theories, then I don't really have a problem with that, hell feel free to throw the word 'know' in there. I know that when you drop your pen that it will fall, and if you tell me what height you're going to drop it from, then I'd know how long it was going to to take to hit the desk, every single time you drop it, I know it is going to accelerate at the same rate. That's because of the reality that we live in and our equations for determining that stuff are correct. But all that is very colloquial... Edited by Catholic Scientist, : see ABE

So I have no idea how you are rejecting some and demanding RAZDian style agnosticism towards others? Because it depends on where you're comming from... In a colloquial or philisophical sense, reject away. In a scientific sense, not so much.

But science rejects all such propositions. I disagree. It doesn't really reject any of them because it doesn't really address any of them. Using Newtonian Mechanics to calculate the amount of time that it will take for your pen to fall to your desk is not a rejection of us all living in the Matrix. Its totally irrelavant and unmentioned and not cared about at all. You seem to want to call that a rejection for some reason...

CS writes:
But it is a rejection of the one second universe proposition. Using Newtonian Mechanics to calculate the amount of time that it will take for your pen to fall to your desk is not a rejection of us all living in the Matrix. As are calculations of the age of the Earth rejections of Last Thursdayism. As are statements about evolution and the origin of species rejections of Biblical Omphalism. As are conclusion made about storms on the basis of static electricity rejections of Thor thrashing his hammer around. No, not really. And certainly not explicitly. You could come up with all kinds of silly scenarios that don't fit with a scientific explanation and then say that that explanation rejects it, but you'd just be making it up. The explanation simply explains what it does, it doesn't really reject competing imaginary scenarios.

Science is based on objective evidence. Untested but evidentially baseless propositions are ALL treated by science in exactly the same way. Yeah: Ignored. But not really "rejected".
CS writes: You could come up with all kinds of silly scenarios that don't fit with a scientific explanation and then say that that explanation rejects it, but you'd just be making it up. Exactly CS!!!!! Well fucking done!!!!! What you'd have been making up, was that the scientific explanation rejects it.
CS writes: The explanation simply explains what it does, it doesn't really reject competing imaginary scenarios. That objectively evidenced explanations are more likely to be accurate descriptions of reality than evidentially baseless propositions would seem to be simply inarguable. Are you denying that this is the case? No, not in the colloquial sense, but from a scientific stance, these propositions are simply ignored, not really rejected.

So you think it is unscientific to say that objectively evidenced conclusions (e.g. evolution of species) are more likely to be accurate descriptions of reality than baseless propositions (e.g. Last Thursdayism)? Its this part that I don't like:

We've started to conflate theories with conclusions....
The nature of being a conclusion (X years) precludes other answers as possibilities (Y days). But theories are designed to work as explanations of the data, they don't necessarily preclude other theories as possible explanations, and they don't judge themselves as being some liklihood of correctly matching reality.

Is it coloquial of scientific to consider the theory of evolution an accurate description of reality and the creation of species fully formed as highly improbable? Is it coloquial or scientific to consider objectively evidenced explanations as more likely to be accurate descriptions of reality than baseless propositions? They both sound awefully colloquial to me... Its common knowledge that scientific theories don't consider themselves to be The Truth. And why would a scientific explanation even address a baseless proposition?

Why do we seek objective evidence as the basis of our scientific theories if objectively evidenced explanations are no more likely to be accurate descriptions of reality than propositions which lack such evidence? One of the other reasons is because it works. Problems get solved, advances are made, and we get shit done, all the while nobody is musing over whether or not we're more accurately describing reality than some other proposition.
Have you ever heard of verisimilitude? Yes, but never in a science class or lab.... Here is a summary - Rather than subjectively picking and choosing which baseless but untestable propositions can be rejected, which need be assumed a-priori and which demand the RAZDian brand of absolute agnosticism why not take the scientific approach and treat all such propositions equally and consistently? Yeah, forget about 'em and don't even address them! Which reminds me that you didn't answer my question:
