You're just wrong, full stop. — Echarmion
Then, by definition, the majority of observers are mistaken about rocks, because that's what the word "illusion" means. — Echarmion
If a rock is what it looks like to you, and you die, a rock is still what it looked like to you. This is just running in circles with words. — Echarmion
Saying a rock is what it looks like to X is not an idealist position, it's a realist position. To an idealist, the rock is nothing in and of itself. — Echarmion
If we no longer see rocks as rock, there must still be rocks, because by the terms of that very sentence, rocks both are a thing in and of themselves and something that people see.
You're entangling yourself in your own word salad. — Echarmion
Of course it's counterintuitive if you say things that are contradictory. Your definition is not a definition, but a tautology. — Echarmion
All good. Half of irrational is still irrational. — Mww
So, when I ask how many hours would pass in a year after we've all died... — S
It's just as nonsensical, to talk about years when there's no human beings, as it is to talk about hours, and as it is to talk about rocks. — Metaphysician Undercover
That's a great argument you've got there. How long did it take you to come up with? Hours, I'm guessing. — S
But they can't be mistaken by your own definition of what a rock is, because the definition would fit. It can't be both. That's the problem. To avoid contradition, you would be forced into to either rejecting your ill-considered definition, or the far greater absurdity of accepting that such an illusory scenario would be impossible. — S
Your definition here would be that a rock is what looks, feels, etc., like a rock to these people. — S
We have what looks, feels, etc., like a rock to these people. So that would be a rock by your definition. The problem with that, is that, really, it could be anything. You might be imagining an actual rock when you do this, but really, it could be a glass of water, a cat, or a microwave, that looks, feels, etc., like a rock. — S
No, you're fallaciously moving the goalposts by switching from present-tense to past-tense. You can't do that. You need to be consistent. If a rock is what looks like a rock to me, then a rock is what looks like a rock to me, not what looked like a rock to me. If I died, then nothing would look like a rock to me. Therefore, there wouldn't be a rock, by your own definition. — S
I'm trying to make the point in a way that will get you to see sense. Your definition allows for a situation with "rocks" (in your sense), that aren't actually rocks (in my sense, which is the normal sense). So, we could take the dictionary definition I gave, and imagine a scenario where there's a rock by that definition, but so long as it doesn't look, feel, etc., like a rock, then it's not one by your definition. — S
I think that that's a problem. And I'm guessing that I'm not the only one. It removes the requirement that reality matches up with our language, and instead goes by a model whereby language matches up with mere appearance, which of course can be illusory, which causes problems for the model, as I've shown. — S
The argument has already been made. Until you put in some effort to actually understand it, you'll get nothing else from me. — Echarmion
Or maybe the problem is that you are using a term - "illusion" - that's already predetermining the answer. It only makes sense to speak of illusions if you consider rocks to have a definition independent of the observations in question. It's a form of begging the question. — Echarmion
Again this is a realist position. An idealist would say that a rock is the looks, feelings etc. — Echarmion
You're still assuming there are things like rocks, cats and microwaves that are things in and of themselves, and then someone comes along and looks at the things and sees a rock. But to an idealist, there are no cats or microwaves either. These words refer to collections of subjective observations. The sentence "I observe a rock, but it really is a cat" makes no sense from that position. — Echarmion
No, you're fallaciously moving the goalposts by switching from present-tense to past-tense. You can't do that. You need to be consistent. If a rock is what looks like a rock to me, then a rock is what looks like a rock to me, not what looked like a rock to me. If I died, then nothing would look like a rock to me. Therefore, there wouldn't be a rock, by your own definition.
— S
My point above applies here. The way you phrase your example presupposes that rocks are things in and of themselves, and that your observations conform to these objects. — Echarmion
If we imagine a scenario where there is a rock that a definition conforms to, we are already in realist territory, and so any conclusions from that are irrelevant to an idealist. — Echarmion
For appearance to be illusory, we'd need to be able to compare it to something, and conclude the two don't match. What are we comparing appearances to? — Echarmion
Can there be an illusion? Yes or no? — S
Yes, I know that. I'm making the case that that makes very little sense for anyone outside of their crazy little world. — S
There are things like rocks, cats, and microwaves. The real things, that is, not mere appearance, which is something else entirely. My finger pointing at the moon is not the moon. — S
As can be seen, we were talking about your definition there. You keep changing the subject. Don't do that. I like to stay on point. — S
That would be a massive problem if you claim that you can't even imagine a scenario where there is a rock that a definition conforms to. — S
Hold on a minute. Don't you think that it's absurd that illusions are impossible? — S
That would be a massive problem if you claim that you can't even imagine a scenario where there is a rock that a definition conforms to.
— S
I did not say that I can't imagine it. — Echarmion
Wouldn't they still be meaningful in the sense that these languages would consist in rules about meaning? — S
What even is a language if not basically a set of language rules about symbols or sounds or whatever — S
So, how do you explain what seems like an illusion? When for example, evidence suggests that I see red as blue? That I see visible light with a dominant wavelength of approximately 625–740 nanometres, but it looks like blue to me? If I didn't know any better, I'd think it was blue? Is it blue or isn't it? :brow: — S
Then I didn't mean you, personally, did I? :roll:
I meant them. Those of the position we're talking about. — S
Even if it's down to bare assertion vs. bare assertion, it doesn't have to end there. One can consider what makes the most sense, what better conforms with our common language use, what has greater explanatory power, etc. Are you interested in that or not? — S
"I'm unable to make sense of what you're saying because I'm not interpreting it right" is not a sensible criticism. It's not a criticism at all, it is an admission of failure. — S
All I have to do is point this out, and I've done that here in this comment, and once is enough, so even if you repeatedly make the same error, I would've already dealt with it. — S
Well, first, I don't believe that languages consist of "rules about meaning" period. I don't know what a "rule about meaning" would even be. I don't believe it's possible to actually speak meanings, by the way --remember that meanings are different than definitions in my view. ("In a language, it would be the case that this word means such-and-such"--that's not a meaning, it's a definition. Also, definitions aren't rules. They're reports--journalism, basically, about conventional usage.) — Terrapin Station
But even aside from that, I wouldn't say that languages are about rules, period. There are conventions in languages, but those conventions aren't rules in the same sense sense of rules of a game, or laws, or rules that some business might have for its employees or patrons ( "no shirt, no shoes, no business") or anything like that. (Even though some folks prone to persnickettiness would like to treat the traditional conventions that they prefer as if they're rules.) — Terrapin Station
At any rate, on my view, x only has meaning insofar as S assigns meaning to x. — Terrapin Station
What I'm asking in what you're quoting is basically this (exaggerated for a moment to make this clearer): why isn't L (consisting of words/expressions x, y, z, grammar G, etc.) a language at time T1 if at T2, S doesn't understand anything about L? — Terrapin Station
In other words, why does L need to be a language at T2, T3, T4 ad infinitum in order for L to be a language at T1? — Terrapin Station
And if L is a language at T1, and it's a private language at T1, then a private language is possible. It would be irrelevant whether any L exists in perpetuity (or at least for the lifetime of the previous users of L, or whatever temporal claim someone would be trying to sneak in). — Terrapin Station
I actually asked with respect to not understanding particular words at T2 rather than the language wholesale (hence the above being an exaggeration), but that was the idea. The assumed "It needs to be the same over time" requirement is untenable--since no language is, and all of the skepticism points about memory etc. apply just as much to public language. Plus the temporal sameness requirement would have to be made explicit, anyway. — Terrapin Station
Languages are tools utilizing symbols (often but not necessarily sounds or marks) to represent objects, concepts, etc. They tend to change, to evolve over time. When they're public, conventions develop, but various conventions occur at the same time, and the conventions can be skirted very easily without any significant detriment to the usefulness of the tool. — Terrapin Station
Very weird. What's a language without rules? I don't even think that that's possible. There are rules everywhere you look. Rules that this word means that, rules that this combination of letters is that word, rules about punctuation, etc., etc. — S
Wait, why the heck are you specifying empirical knowledge?! That's doing it wrong. I'm not asking about empirical knowledge of the rock! I thought I made that clear, multiple times. Empiricism is a useful tool, but it is not suited for all jobs, and it is the wrong tool for this job. I'm just asking about whether we know that there'd be a rock. — S
please don't interpret "reasonable enough" or "knowledge" as requiring absolute certainty — S
Actually, I did know that. — S
Proof generally seems to be about sufficiency, — S
I might call that "knowledge", whereas you might not. — S
I think that that's a problem. And I'm guessing that I'm not the only one. It removes the requirement that reality matches up with our language, and instead goes by a model whereby language matches up with mere appearance, which of course can be illusory, which causes problems for the model, as I've shown. — S
I don't understand what you are trying to tell me. — Echarmion
You are describing different arguments, are you not (argument from language, argument from predictive power etc.)? If you think the question can be solved with arguments, then we ought to argue. If it can not then arguing is pointless. — Echarmion
I want to just do a small bit at a time, especially because some of this I already addressed. Even this little bit is a few different topics.
"Rules that this word means that"--again, this isn't meaning, it's definition. They're different. Definitions aren't rules. They're reports of common usage in some population.
Likewise, spelling, grammar, etc. present conventions. Conventions are different than rules. — Terrapin Station
I am specifying empirical knowledge because you are demanding knowledge of a physical object. Asking about whether there would be a rock must use empirical knowledge because you’re still asking about a physical object. Hence the dialectical conundrum, re: empirical knowledge a posteriori is not suited because there’s no direct experience, we’re all dead remember, and empirical knowledge a priori cannot give the answer you insist is correct.
You’ve asked a million times, and got back the same answer every time......it can’t be empirically known whether there would be a rock; reasonably believed, sure; known.....nope.
Obvious to the most casual idealist observer. — Mww
Nobody does that. “Reasonable enough” and certainty are mutually exclusive, and “knowledge” is never absolute. — Mww
No. No it doesn’t. Proof has to do with necessity. That which is contingent cannot be a proof. — Mww
I call “knowledge” the condition, or the state, of the intellect. What do you call it? — Mww
I’m back. I packed a lunch, got my walkin’ shoes on, went looking for cats and optical illusions. Didn’t find any. — Mww
"If we imagine a scenario where there is a rock that a definition conforms to, we are already in realist territory, and so any conclusions from that are irrelevant to an idealist."
That means that if you were an idealist, then you couldn't even reasonably imagine a scenario where there is a rock that a definition conforms to, because, if what you say is true, that's realist territory.
But if an idealist can't even do that, then that's a big problem. I can. Lots of other people can. It seems to make sense. The idealist is abnormal, and this requires an explanation. I think that the best explanation is that they're doing something wrong. — S
It's not my fault if you apparently can't help but misinterpret the question. — S
The problem here though, is that I've asked you to explain what you mean, in a way that does make sense me, and you've failed to do that. — Metaphysician Undercover
There is no point to even trying to communicate with an attitude like that. — Metaphysician Undercover
Okay, so in your language game, you call them something different. Those are your rules. — S
I did not mean to imply that an idealist cannot imagine realist scenarios.
What I wanted to point out is this: you're constructing thought experiments to serve as arguments against idealism. If you begin those thought experiments with the phrase "let's say rocks are what most people think rocks are" then your thought experiment starts with a realist assumption.
So if, in the course of your thought experiment, you come across a contradiction or an absurdity, you have constructed an argument against realism. Which, presumably, is not what you intended. — Echarmion
It's not a rule, just the result of analysis. — Terrapin Station
Okay, so in my language, it's a rule, and in your language it's just the result of an analysis, even though we're talking about the same thing. The two languages translate. — S
If I’m misunderstanding over and over, why aren’t you telling me how? Your experiment is really simply worded, which implies simple responses. Now, I did find reference to “hidden premises” on my search for cats and optical illusions, but I’m going to ignore those because hidden premises amounts to a guessing game along the lines of Russell’s teacup, which doesn’t interest me. — Mww
Your calling what we know “knowledge. “Knowledge” is what we know. “Thoughts” are what we think. “Feelings” are what we feel. “Experiences” are what we experience. “Anything” is any thing.
Yikes. — Mww
There's, for example, a term--"cat," say, and a definition, "a small domesticated carnivorous mammal with soft fur, a short snout, and retractable claws . . . "
Objectively, that's a set of ink marks on paper, or activated pixels on a screen (however it works, exactly, re computers), or sounds someone uttered, etc. It's handy to have a term that cleaves the difference between this and the mental activity we engage in to make an association between "cat" (the ink marks or sounds) and "a small domesticated carnivorous mammal" (other ink marks, sounds, etc.), as well as the mental activity of picturing and conceiving and so on.
So I don't know that we're talking about the same thing. There are different phenomena to pick out. — Terrapin Station
