The problem is that, as you agree, most features of reality don't identify themselves.
You've said something along those lines several times. I don't understand what that means. Of course things don't identify themselves; that makes no sense. Identifying is something we --- us sentient, verbal creatures --- do, with regard to things. Are you claiming that in order for there to be a correspondence between A and B, those two things must somehow identify themselves? How would anything "identify itself"?
For example, what we call blue isn't a self-defined thing, because the visible colour spectrum is continuous.
I have no idea what a "self-defined thing" might be, either. As with identifying, defining is something we do, not that (non-sentient) things do.
So to say the name 'blue' corresponds with the thing that is blueness is false.
Well, that appears to be a conclusion derived from the two nonsensical statements above, regarding self-identifying and self-defining things. I find that argument incoherent. Perhaps you can explain what you mean by "self-identifying" and "self-defining."
With respect to the correspondence between the word "blue" and a range of colors, that the spectrum is continuous is irrelevant. Color words are inherently vague; where blue-green transitions into blue is not precisely defined and somewhat subjective. But that doesn't preclude a correspondence between the word "blue" and that portion of the spectrum. There is a correspondence if, when the customer says, "I'll take the blue one," the merchant hands him the blue baseball cap --- which will happen 99+% of the time.
Okay. But that demonstrates the pervasive conflation of what we say about things (in predicates, which are linguistic expressions) with the way things are. It's a powerful and deep delusion, which is why it has seemed natural to believe the two different things are the same, for so long. (And, btw, do you think existence is a predicate?)
What is the pervasive delusion is the belief that we have some knowledge of "the way things are" independent of what we perceive and what we say about those percepts. We don't. All I know of the way things are is what I perceive. All I know about what you perceive is what you say about it. There are simply no grounds for any claim that "the way things are" differs from what we perceive and say about them.
False analogy. Painting a house is nothing like naming it. 'The house is white' ascribes a property - it describes the house. But I still think it would be odd to say that being called a house is one of the properties of houses. 'List the properties of those things.' 'Well, we call them houses'. Perhaps that sounds natural to you, but it doesn't to me.
I suspected you'd challenge that analogy after I wrote it. I shouldn't have used a physical property. The question was whether there is a difference between naming and describing. I agreed those are two different operations. So instead of painting the house, how about building it? Building a house is a different operation that describing it. But is "built in 1890" not a property of the house? Living in a house is not describing it either. But is "Elvis once lived here" not a property of the house? Do those facts not describe the house? The realtor trying to sell it would certainly think so.
Of course it would sound odd to add "they are called 'houses'" to a list of properties, because in most cases that would be obvious to the listener. But how about, "It was named 'Falling Water' by the architect"? Is that a property of the house?
This is confused. Explaining (describing) how we use the word 'truth' and its cognates is nothing like describing a thing such as a dog or a house.
Really? In what relevant ways are they different? You just used the word "describing" yourself, to make your point. Of course, a description of the uses of a word will differ in substance from the description of a dog --- the desciptions of any two distinct things will differ from one another in substance --- but they are clearly both descriptions.
And your equivocation - 'everything is a thing of some kind (that is a tautology)' - is laughable: if a thing is a thing, then it exists and can be described. Please.
Well, again, you appear to be restricting "exists" to a subcategory of existents (those with physical properties and spacetime coordinates). But that restriction is at odds with ubiquitous, common uses of that term. So is restricting "thing" to that category of things: "What is this thing called love?," "Things that go bump in the night," "Is everything OK?," "He's doing his own thing," "The interesting thing about this idea is . . .," etc., etc.
I really can't believe you're being serious - or honest - here. 'What we call truth is not a thing of some kind that exists and can be described'. 'So, you're saying truth doesn't exist?' I'm inclined to say - grow up. If you don't see how childish that is, we may as well stop now.
Sorry, Peter, but "Truth doesn't exist" does indeed follow, quite obviously, from, "What we call truth is not a thing of some kind that exists and can be described." You're saying there that 1) truth doesn't exist, and 2) truth cannot be described. Both of those claims are obviously false. You fail to see that because you impose that arbitrary, idiosyncratic restriction on the term "exists."
Again, I find your misunderstanding hard to credit. A language is nothing other than linguistic practices. So how can those practices follow from a language? This is more nonsense.
Perhaps we have a different understanding of what counts as a linguistic practice. I take "linguistic practices" to denote the things we say. The language is the tool we use to use to say them. The practice of medicine is the treatment of patients; the practice of carpentry is building houses. The scalpels and syringes and instruments the doctor uses are tools of the trade, as are the hammers and saws the carpenter uses.
If p is true iff s, and you say s is a linguistic construct (a p) - then the definition is useless: p is true iff p.
Er, no. Though they are both linguistic constructs, P is not s. Those variables denote specific constructs.
