They do not match over time (or geography) at the societal/cultural level is what I was getting at - the dominant metaphysical framework of the time/location determines what is "true", and often even what "is".

Also: science can change its story whenever it likes[1], and this is to its benefit (of reputation) rather than its detriment.

Science has the best rhetoric/marketing game in existence imho. Whether it is the best possible remains to be seen.

[1] Christianity did this too with The New Testament, which satisfies those who subscribe to that framework, but it is highly vulnerable to an attack from other ideologies with better game (currently: only science).

Yeah, I agree with you on the truth front. It's a pretty slippery concept, and indeed our best "model" of truth has changed many times, even in realms like mathematics where you'd think that stuff would have been nailed down by now.

But I also think you're making a bit of a map/territory conflation. I think what "is" has nothing to do with human culture - you drop a rock from head height, it's going to hit your foot, and this is "true" (observable maybe a better word) regardless of who you are (and more importantly, regardless of what you claim!). This is what I meant by the stories matching over time in some domains.

The ontological claims (the "map") change all the time in science, as they must! But I don't think reality (the "territory") does, in the same way that the ocean doesn't manifest dragons if I draw one on a seafaring chart.

Completely agree that science may not be the best epistemic theory possible. In fact, I'd stick my neck out and say that the scientific habit of reductionism seems to be floundering for things like complex biological systems (brains/ecologies/controversially even consciousness?) and maybe even understanding machine learning models. Perhaps we'll see some interesting developments in the next few decades =)

Right....but:

- what is that has nothing to do with human culture (or consciousness, or the machines we build) is only a subset of the larger set of what is

- quite often, humans drop rocks and other things onto the heads of other humans - religion has always got a lot of blame for this phenomenon, but a lesser known fact is that science plays a massive role in it as well: giving us the technology to do it in ever more powerful and affordable ways

Some stories match, some do not. Religion also has plenty of each.

Dragons may not exist in The Universe, but that doesn't mean they can't can exist in reality.

If you don't believe me, go do a survey of the general public about things that "don't exist" and see what kind of results you get. For bonus results, try disagreeing with some people and see how that goes over.

You and I are members of an exclusive group!

Yes...perhaps we will!

Ah, I think I'm starting to see where you're coming from. I'm using "reality" in the pretty narrow sense of the physical universe (Popper's world 1?), which I guess is actually quite hypocritical given that I'm also attacking the common (semi-religious) belief that everything can be reduced scientifically to fundamental physical interactions.

Ideas seem to have a dynamics of their own, and I'm pretty open-minded to the possibility that things which exist in the collective human mental substrate (world 2?) can exert causal influence of their own, in a certain sense, on world 1. In a way that maybe can't be reduced to physical interaction in any kind of useful predictive fashion?

I don't have the language to think about those concepts clearly right now!

You've left me with lots to ponder, thanks =) it's actually very cool to see Popper himself talking about the metaphysics of this stuff. Some of my physics friends would probably be a bit shocked by that...

Popper's three worlds is one of my favorites to lay on science fans, because they typically love them some Popper, and an enemy in their own ranks is just too good to go to waste!! :)
