No, a noun doesn't guarantee the existence of whatever it refers to. I'm not sure how you could have jumped to that absurd conclusion. A deductive statement need not be empirically true, only logically valid. "All unicorns are unicorns" is a valid statement, despite the fact that there are no such things as unicorns.

No, nouns and their corresponding adjectives do not convey the same meaning. If they did, they'd be the same words.

Help me out, I don't speak english very well.
What we call reality, the objetive world, the physical world, you name it, it 'is our view of the world.
Truth is our interpretations of the sense data, what we all agree that happens, what we can share.
You can desagree in various matters, but you can't desagree in logical thinking, not matter how hard you try, you can't think ilogically, so logic is an agreement. The scientific method is another tool of agreement. Reality is what we all agree to be true using language.
You can't say that truth must be true, that sentences has no meaning at all. Can I say that every object with length either has a meter long or that it hasn't? Answer is NO, theres one thing that have length but I can not say that it is a meter long or that it's not. That thing is the International Prototype Meter.
"A = A" is one thing, but you are doing something different with "A truth must be True" [...]
[...], what you can say is "truth = truth" and that says nothing. All your reasoning is based upon a senseless statement, that every truth must be true, that is the same as to remain in silence.
Sorry if I can't make myself clear. I though that I could do it but I can't find the right words.
Good Luck.

All dogs doesn't have 4 legs, which is why "truth" is subjective, can be alterd, and uncertain.
"Every falsehood must be false", no? There are misunderstandings, there are lies, and intriques ..etc.

1. There are no "deductive statements". Only arguments (or reasoning) can be deductive. There are no "valid statements" either for the same reason. All unicorns are unicorns is a truth of logic. In fact, it is an example of a logical truth, also known as a tautology. And, in fact, it is true that all unicorns have a horn on their heads, since what that sentence means is that if anything is a unicorn, then it has a horn on its head. And that, of course, is true. But, I agree that the use of a noun in no way implies that the noun refers to anything. If all nouns referred to something then Santa Claus exists would be necessarily true, and Santa Claus does not exist would have to be necessarily false, and obviously the first is false, and the second is true.
2. I (of course, now could anyone not?) agree that every truth must be true (which is false) could not possibly mean the same thing as it must be that every truth is true, since the latter is true. And what is false and what is true, could not possibly mean the same thing.
3. Every falsehood must be false is, itself, false. What is true is that it must be that every falsehood is false.

It was you to disqualify "every truth must be true" on the ground of "truth" being a noun while "true" is an adjective, as if because of that "being a truth" were different from "being true," which it is not. So I concluded that for you "truth" has an objective existence granted by its being a noun while "true" is left to oblivion because it is a mere adjective. If there is another conclusion to draw from your argument, please let me know.
So, according to you, "dead" and "deceased" must have different meanings, for they are different words.
Remember The Beatles? They had a song: "I say yes, you say no," and I suspect we will not go too far just doing that. It is not enough to say no, you must both clarify your point and justify it.
Of course they aren't the same thing: having four legs refers to a universe far bigger than being a dog. However, if all four-legged things were dogs, then they would be the same, since all dogs are four-legged things, don't you agree?
So you were indeed wrong?

Point well taken.

The conclusion that I already explained: "truth" is something, "true" describes something. You, on the other hand, think that the description of something is the same thing as the thing described. That is manifestly false. If I were to say "all truths are beautiful," would you then conclude that "truth" is the same thing as "beautiful?"
guigus wrote:So, according to you, "dead" and "deceased" must have different meanings, for they are different words.
Indeed, they do have different connotations.

I have explained my position. There's no need to go over it again.

You're confusing the principle of identity (A is A) with a simple conditional (if all As are Bs, and C is an A, then C is a B). You have made some sort of claim based on the principle of identity. Try to stick to the subject.
guigus wrote:So you were indeed wrong?
No, I was just agreeing with something that you said that actually made sense. It wasn't really relevant to your argument or to mine, so I'm not sure how that would make me wrong. But at least it made sense, so I guess that's one in a row for you.
If you agree with "A is A," then you must agree that "every truth must be true" as long as it means that "every truth must be a truth." But you are right in saying I am "doing something different" with "every truth must be true": indeed, I am correcting "A is A," since it is not applicable to falsehoods.
Man you are so confused. Fortunately there is simple way out of that confusion: just replace "every truth must be true" by "every truth must be a truth," then ask yourself if a truth can be different from its being true.
Wow! Die hard 5.o! I guess you are thus willing to hold that being true has a different "connotation" than being a truth?
More confusion. My subject is the necessary truth of any truth (no adjectives here, for your despair): being true is the same as being a truth, which is why "every truth must be a truth" and "every truth must be true" have identical meanings.

Is not the same to say "Truth must be True" (A truth must be a truth is the same thing), there is no ethics in lógical thinking, there's no "must be". If yoy say "Truth is truth", that is the same as to not say anything, is a tautology. Truth is truth becouse it is.
So truth is what it is, but theres nothing beyond what we call truth to giv truth it's escence of truth. All that there is is uses of the word truth where you can say that truth is a lie or viceversa, but that is linguistics.
I don't desagree with your sentence "a truth must be true", I never said that I desagree, I said that that sentence has no meaning, I can't agree or desagree with it. You CAN say it, but it is a taotology, it isn't true or false.
Now in other order of thinking, you can indee say that "a Truth must be a Truth" if the word truth does not mean the same at the begining of the sentence and at the end. So the second truth is a cuality of the first. this is another game of language, it has sense, but no longer is "A = A".

The fact that you're fighting so hard against adopting "every truth is a truth" as your "A is A" principle is sufficient to show that even you think there's a difference between it and "every truth is true." If, however, you're now willing to adopt it, then I would have no objection.
guigus wrote:Wow! Die hard 5.o! I guess you are thus willing to hold that being true has a different "connotation" than being a truth?
Of course it does. It has a different denotation as well.

Give it a rest.
How about explaining what you mean by "if we say that every falsehood must be false, then we are saying that every falsehood must be the truth it falsifies."

By saying that a falsehood must be false (that its falsity must be false) you are denying that it can be a falsehood.
Hence, you are saying that it must rather be true.
And since this truth is the one it would falsify were it false, you are saying it must be the truth it falsifies.

And I never said that either. I gave you this opportunity to explain what you meant, not to invent an argument that I never made. Would you like to take another stab at that?
