“Again that’s ambiguous between “reality doesn’t exist” and “we don’t know reality”.
It happens to be the case that in English the word “reality” can be used both ways. You can use it in a territory sense, to mean an object of knowledge—this book is non-fiction, so it is about reality; and you can use it in a map sense, to label a successful representation—this portrait is highly realiastic.
But that’s only a quirk of English, not a deep insight!”
It’s only ambiguous if you don’t understand it. It’s pretty clear to me. It’s saying that knowledge doesn’t really correlate to some independent reality “out there” more like it just has to be internally consistent. It’s not what you’re saying.
But no, reality isn’t used that way in English, it usually refers to “what is” absent any limiting factors. It’s not used to mean a successful representation, that’s a different word. But of course the problem is that you can’t really know what “is”, as that question is just turtles all the way down.
I’d also call that a deep insight, not a quirk of English, especially since language is what we have to navigate and make sense of all this stuff (well I’d scratch the insight part since it’s not really accurate).
“So is realism. But anti realism needs to be supported somehow, because it’s not the default...the default is that theories are explicitly held to be about reality.”
Ironically no, it’s realism that has to be supported, but everyone just assumes it’s the case when really the burden is on it not anti-realism. Anti-realism isn’t making any additional claims while realism is.
“Whatever that means. It’s not a fact that QM has to be interpreted subjectively. QM describes a reality, but a non classical reality. You said so your self:”
You misread what I said, QM actually might suggest that there is no “objective and independent” reality. That means all reality.
“It’s an explanatory hypothesis.
https://en.m.wikipedia.org/wiki/Abductive_reasoning
Explanatory hypotheses are justified by the work they do in explaining observations. The problem with instrumentalism and antirealism is that the same work is not done in another way...you have to settle for less.”
It’s not, it’s an axiom that you hold. Also “plausible” seems weak given the host of philosophical arguments made that undermined abductive reasoning. There is no real “problem” with instrumentalism and anti-realism, they’re honest in their claims about the world and the limits of human ability.
Again you’re asserting something without evidence, and what is plausible can very from person to person, it’s not really an objective standard for what is likely. Descartes pretty much blew a hole through that one too.
“I wouldnt, because its an error to suppose that no concept can refer, and no proposition can correspond. Its just missing the very basic fact that maps are intentional.
https://en.m.wikipedia.org/wiki/Intentionality″
Or maybe they’re not, like I said it could refer to nothing outside, just that it has to be internally consistent, in which case anything could work.
“Yudkowsky? I don’t think he really means that , and I’m not defending him anyway. Just because his version of realism is broken—if it is—doesn’t mean mine is.”
Most folks here seem to, some even saying people are biased just because they want patterns of atoms to be people, whatever the hell that means.
“Explain why scientists conduct experiments. How can that be relevant to internal consistency?
Explain why it is impossible for human knowledge to correlate to reality, even by accident. Is it because there is no external reality , as you sometimes say?”
It’s how science is. Science itself admits that it doesn’t prove anything and that our knowledge might be more instrumental than about reality itself. It’s the first thing you learn and something each of them keeps in mind, that it could all be wrong, but it works.
As for external reality, I cannot say for sure, and there are plenty of arguments that show that skepticism about external reality cannot be refuted.
“https://en.m.wikipedia.org/wiki/Realism_(arts)″
Do I really have to spell out why that doesn’t meant much? It just reflects how humans perceive it, not that it corresponds to reality itself.
“Expand on that please?”
It’s mostly based on Kant’s idea that reality is only as it ever appears to us and there is no way to really know if you are at the ground level or if there is another one underneath it. Even if you get out of the simulation you only know that world wasn’t real, you can’t say that about the new one. It’s just turtles the whole way down.
“That’s a common fallacy. It’s still an experimental science.”
It’s actually not.
“That’s just contradiction. You need to argue your points.”
There is nothing to argue when you assert something without evidence. External reality is an axiom we hold, it cannot be proven.
“They obviously are. A map of Sweden represents sweden.”
Well no, it represents the idea of Sweden.
