Wrong. It's referring to the sentence "this sentence has ten words", which is to say that it is referring to "this sentence has ten words". — TonesInDeepFreeze
You skipped my argument, for the second time (as now revised to use 'stirng' instead of 'sentence'): Suppose we define 'the Pentastring' as the "This string has five words". So, we have a subject from the world, viz. the Pentastring. So, "The Pentastring has five words" is meaningful. — TonesInDeepFreeze
The glaring sophistry in that video is the claim that "this sentence" equals "this sentence is false." — TonesInDeepFreeze
The physical inscription on the blackboard is made of chalk. The physical inscription in the notebook is made of pencil lead. There are two inscriptions. But there is only one sentence involved. — TonesInDeepFreeze
The ball is in your court to support that claim — TonesInDeepFreeze
In your post you present eight complex linguistic and logical problems, each requiring the time it deserves, meaning that I only have the time to answer them one by one. — RussellA
the predicate "has five words" is referring to the subject "sentence A". — RussellA
the subject is "the sentence "this sentence has ten words"" — RussellA
The glaring sophistry in that video is the claim that "this sentence" equals "this sentence is false."

"A cat" may be defined as "a carnivorous mammal long domesticated as a pet and for catching rats and mice". — RussellA
"A cat" refers to "a carnivorous mammal long domesticated as a pet and for catching rats and mice". — RussellA
the two expressions are not linguistically equal (one is two words long and the other is fourteen words long) [...] — RussellA
[...] they are semantically equal, meaning that one expression can be replaced by the other. — RussellA
If in the expression "this sentence is false", "this sentence" refers to "this sentence is false", its self-referential nature means that no meaning can be determined within a finite time, meaning that it becomes meaningless. — RussellA
The ball is in your court to support that claim

I wrote: Possibility 2) If "this string" is referring to itself, then it is an empty reference, and the set of words "this string has five words" is meaningless, isn't a sentence and has no truth-value.
Like I said, the ball the ball is in your court to demonstrate that claim.
— RussellA
But if "this string" refers to itself, then it is impossible to know what it means, and if no-one knows what it means, then it becomes part of a meaningless set of words. — RussellA
Suppose we define 'the Pentastring' as the "This string has five words".
So, we have a subject from the world, viz. the Pentastring.
So, "The Pentastring has five words" is meaningful.
To determine whether the Pentastring is true, we determine whether the Pentastring has five words.
Put this way:
In "This string has five words", 'this string' refers to the Pentastring, which is in the world. And "This string has five words" is equivalent with "The Pentastring has five words", in the sense that each is true if and only if the Pentastring has five words. So, "This string has five words" is meaningful.
To determine whether "The Pentastring has five words" is true, we determine whether the Pentastring has five words, which is to determine whether "This string has five words" has five words. To determine whether "This string has five words" is true, we determine whether "This string has five words" has five words. The determination of the truth value of the Pentastring is exactly the determination of the truth value of "This string has five words". — TonesInDeepFreeze
The predicate "has five words" is referring to "the sentence "this sentence has ten words""
— RussellA
Wrong. It's referring to the sentence "this sentence has ten words", which is to say that it is referring to "this sentence has ten words".
The sentence "this sentence has ten words" is "this sentence has ten words".
The sentence "this sentence has ten words" is not "The sentence "this sentence has ten words"".
And if your argument is supposed to be addressing mine, then no matter anyway, since I didn't use a construction "the sentence "this sentence has five words", and even if I had, your argument would be wrong since:
The sentence "this sentence has five words" has five words
is not saying
"The sentence "this sentence has five words"" has five words

And now I see that you have a serious misunderstanding of how quotation marks work. Just as with the video that is you inspiration, you don't understand use-mention as you flagrantly fail to use quotation marks correctly. — TonesInDeepFreeze
The use-mention distinction — TonesInDeepFreeze
"This string" and "This string has five words" are interchangeable. (False) — TonesInDeepFreeze
regards use, Big Ben is the bell inside the clock tower. — RussellA
regards mention, "Big Ben" is "the bell inside the clock tower" — RussellA
it is the expression "this sentence" that is interchangeable with the sentence "this sentence is false" — RussellA
the one hand there is i) "this sentence" and on the other hand there is ii) the expression "this sentence". These are different things. — RussellA
should negate your doubts regarding interchangeability. — RussellA
In the sentence "this sentence is false", what does "this sentence" refer to?
It could refer to the sentence "the cat is grey in colour". — RussellA
Or it could refer to the sentence "this sentence is false". — RussellA
In which case the sentence "this sentence is false" means that the sentence "this sentence is false" is false. — RussellA
we know that the sentence "this sentence is false" means that the sentence "this sentence is false" is false. — RussellA
This — RussellA
means that the sentence ""the sentence "this sentence is false" is false" is false — RussellA

"Big Ben" has two words. "the bell inside the clock tower" has six words. So "Big Ben" is not "the bell inside the clock tower". — TonesInDeepFreeze
"Big Ben" and "the bell inside the clock tower" are not the same expression — TonesInDeepFreeze
The teacher writes on the blackboard, "Caesar was a Roman emperor". A student writes in her notebook, "Caesar was a Roman emperor". The physical inscription on the blackboard is made of chalk. The physical inscription in the notebook is made of pencil lead. There are two inscriptions. But there is only one sentence involved. — TonesInDeepFreeze
As the expression "the bell inside the clock tower" refers to the expression "Big Ben", not to Big Ben as a thing in the world, — RussellA
I would say just mention not "mention" — TonesInDeepFreeze
It's not rocket science.
We use a word to mention a thing.
We use a word in quote marks to mention the word. — bongo fury
