When I refer to "the periodic table", I mean to say that I could explain atomic theory down to the level of the periodic table to a symbol manipulating alien intelligence. Whatever the standard model of particle physics becomes, chemistry will depend on the information that structures the periodic table. We don't have to use the word "objective" if that seems like a "magic word" to you. That's more or less what it means to me. Likewise for mathematical expressions of the evolution of dynamical systems, all done with various equivalent formulations of classical mechanics. Likewise with various equivalent mathematical expressions for the probabilities of the occurrence of statistical events. The point I made is that the concepts of dynamical evolution, statistical probability, and atomic theory will work for those alien symbol manipulators just as they do for us in predicting the outcomes of experiments. Experimentation is a methodology.
Ok, I have no problem with what you're saying here, but that's exactly the point.
Just like chemists will continue to use the periodic table, and mathematicians will continue to use the various forms of mathematics, architects will continue to use Euclidean geometry.
No architect will think I'm somehow dissing architecture or Euclidean geometry when I say Euclidean geometry's not true though, no-one familiar with Euclidean geometry will claim it's true, or objective in the first place, it's a well proved fact that Euclidean geometry is neither true nor objective. That's not the same as saying it's not worthwhile, not useful etc. etc.
So what do can we think when someone starts to claim that it is true, or objective? Only that this person is being dogmatic, and ignorant about it.
Do we really want to allow this to become how scientists think or behave about science?
Religious people often claim that science is "just another faith", and no-one around here reacts well to that claim, nor should they, but they
should take the risk of science becoming just another faith seriously, because it is possible, and the first step on that road is the claim that science is true, or objective.
When I see people making arguments that science is true or objective, I don't see people educating their listeners into science, I see them indoctrinating others into their faith.
Saying "it's a methodology" doesn't alleviate this, because even if we tried, we simply couldn't have every person in the world become a scientist, and have some kind of esoteric understanding of what's "really" meant when a scientist says "objective" or "true", in my experience, people who make those claims don't understand exactly what they mean, they don't "really" mean anything beyond "this is my view, and it's The Right One". That's anti-science imo, it's subtle, certainly far more subtle than something like Creationism, but that makes it more effectively anti-scientific, not less anti-scientific.
If someone tries to tell me "science is moving toward truth", I would try to point out these or similar matters, and try to make "objectivity" a bit less of a "magic word". What I think you are talking about is explaining an alternate methodology to someone who continues to apply magical thinking to the world. Dennett has some interesting things to say about the differences between "real magic" and "stage magic" (or conjuring tricks). "Real magic" is an oxymoron, just like "scientific truth". The two words simply do not belong together, and we are in agreement on that. It is natural language that is at fault, not the language of mathematics. There is no ambiguity, for example, in the mathematical description of probability, or in classical dynamics of particles and systems. There are ways to obfuscate "entropy", but we're not impressed by obfuscation, are we? "Magic" is not really an "alternative methodology", is it? YK, in the sense of "alternative medicine"? There is just no such thing as "alternative spectroscopy"! One might say that this is an attempt to clarify "objectivity". One might say that "magic" is "alternative experimentation", and it depends on obfuscating its results, or that "paranormal" is an attempt to obfuscate the concept of "magic".
No we're not impressed by obfuscation, and that's why I think we should be as clear as possible, science isn't objective, it's not true, it's not even concerned with these things, they're obsolete concepts grounded in mystical magical nonsense. We have other words that work better, and are more apt, like inter-subjective, and if inter-subjective leaves us with the possibility that a scientific idea can be wrong, a delusion, that's not a weakness, scientific ideas can be wrong, can be delusions, and we'd be well advised to remember the fact.
It might make our rhetoric weaker, but we're no more impressed by rhetoric than we are by obfuscation are we?
That people feel miffed when their pet theories are not universally accepted is not surprising. Scientists do get miffed, but it always shows up when they do it within their professional capacities.
But who could tell? We have o accept the fact that the vast majority of people aren't scientists, and as science progresses, fewer and fewer are going to be scientists with the right kind of specialization. If we allow this idea that science is true, or objective, we run the risk that those who aren't part of the relevant scientific sub-community are going to get back into that old time religion, just it'll be called science next time. Why allow the risk for the sake of using a few words that we know are only of rhetorical value anyway?
The notion of semantics is tested whenever we try to communicate with an organism (evolved dynamical system) that is not human.
It's tested when we talk to anyone. At the very least some grasp of semantics, and logic can allow us to identify when we don't understand something, and that's all that's needed.
Why worry about life forms we've not yet encountered? We have enough semantic difficulties with other humans, but for the most part they rely on other humans not being able to identify things that they don't understand, get rid of that, and many of our problems go away. Is it easy to get rid of it? I'd doubt it very much. Is it possible? Definitely, the major difficulty is in getting people to bother doing it. Those of us who want to foster a more rational skeptical outlook, should undertake to do it ourselves though.
So far we don't have a big enough sample space really to know what we are talking about. It's quite likely we never will, and so semantics will be the touchstone of relativism for the forseeable future. Sadly, for the time being, we have no means of "getting the semantics right". Maybe with mathematics, which is how scientists communicate when they "care enough to send the very best".
I don't agree, I think some of us just have a conviction we can't get the semantics right. I don't see any evidence to support this view. Perfect communication is impossible, but unnecessary, we just need to refrain from saying more than we can evidence, and that only takes a small amount of effort.
There are people who do not understand scientific theory, or mathematics, yet think they understand something called "philosophy", but they are not my concern. When they understand both, we can have a conversation.
I don't see any reason they should understand these beyond having some familiarity, nor do I see why these are necessary to do anything useful.
This conversation requires little understanding of either for example, I'm neither a mathematician nor a scientist, I don't see that I'm failing to hold up my end of the conversation either though.
Here's an example: Gunplay. Designing a gun is all about chemistry, with a little bit of mechanical engineering to link the trigger to the firing pin. Gas dynamics, chemistry of gunpowder, ballistics (and supersonic flight through the atmosphere). Strength of materials (for the firing chamber and so on). Even your kevlar vest, all about "better living through chemistry"!
What's this an example of though? That we can produce guns every time? Great, and I'm not being dismissive there, but do you really think every problem humans face is solvable in the same way producing a given mechanism is? I don't. Some, many even, may be completely insoluble, but again, we're not interested in magic are we? Do we need perfection? I don't think so, we can improve situations even if we're incapable of perfect solutions, I don't see that a problem's being difficult or impossible to approach with science means it should be ignored, or dismissed, that's just more magical thinking from my point of view.

It's not a coincidence that pragmatism emerged after the discovery of the theory of evolution, the final clinching evidence for the fact that humans are just another species of animal. We aren't little gods or immaterial minds and our ways of thinking stand as much in need of naturalistic explanation as any other type of animal behaviour.
Replace "naturalistic" with "effective" there and I agree completely. Saying "we need solutions" is scientific, saying "we need solutions that fit our preconceptions" is religion.
