'X' doesn't refer at all, it's a type of action that gets a job done — Isaac
If you take take means as has the same extension as, then yes. Otherwise, no, or depends. — Srap Tasmaner
Tarski emphasises that the (T) schema is not a definition of truth – though in spite of his insistence he has been misunderstood on this point. It is a material adequacy condition: all instances of it must be entailed by any definition of truth which is to count as 'materially adequate'. The point of the (T) schema is that, if it is accepted, it fixes not the intension or meaning but the extension of the term 'true' [my emphasis].
1. Truth-Conditional Semantics
A truth-conditional theory of semantics is one which adheres to the following dictum: To know the meaning of a (declarative) sentence is to know what the world would have to be like for the sentence to be true. Put another way, to give the meaning of a sentence is to specify its truth conditions, i.e., to give necessary and sufficient conditions for the truth of that sentence. (Note, by the way, that we are using "true" to indicate something like "corresponding to the way the world is." We are thus implicitly adopting a correspondence theory of truth.) — Dowty, Wall, and Peters (italics in original)
That's why it must be a consequence of any substantive theory of truth. — Srap Tasmaner
But exactly what kinds of definition will the material adequacy condition rule out? In answering this question I shall use a weakened version of the criterion: not that all instances of the (T) schema be deducible from any acceptable truth definition (Tarski's version), but that the truth of all instances of the (T) schema be consistent with any acceptable truth-definition. The reason for this modification is simply that the weakened adequacy condition is much more readily applicable to non-formal definitions of truth. Now it is to be hoped - and perhaps even expected - that it will allow the sorts of definition which have been seriously proposed, and disallow what one might call' bizarre' theories. But matters turn out rather oddly. Consider the following definition of truth, which seems to me definitely bizarre: a sentence is true iff it is asserted in the Bible. Now it might be supposed that this definition (I shall call it 'DB' for short) does not entail all instances of the (T) schema, not, for instance:
'Warsaw was bombed in World War II' is trueB iff Warsaw was bombed in World War II.
Now it is indeed the case that someone who did not accept DB might deny:
'Warsaw was bombed in World War II' is asserted in the Bible iff Warsaw was bombed in World War II.
But further reflection makes it clear that a proponent of DB could perfectly well maintain that his definition does entail all instances of (T); he may allow that 'Warsaw was bombed in World War II' is true, but insist that it is asserted in the Bible (in an obscure passage in Revelation, perhaps), or if he agrees that 'Warsaw was bombed in World War II' is not asserted in the Bible, he will also, if he is wise, maintain the falsity of the right-hand side of the above instance of the schema. So, rather surprisingly, Tarski's material adequacy condition cannot be relied upon to be especially effective in ruling out bizarre truth-definitions.
'Warsaw was bombed in World War II' is asserted in the Bible iff Warsaw was bombed in World War II.
there is no other conceivable way to do so — Srap Tasmaner
So I think, yes, this is all about our shared would, but I don't think the co-operation this is all here to allow requires an actual set of word>reference facts that are external to our intentions. It simply requires that we're similar enough in intentions and co-operative enough in policy that we can see evidence, in another's behaviour, of what we need to do to bring about the state of the world which includes helping the other. — Isaac
You mean if I wrote something like this?
Kp ⊢ p Kp ⊢ p
Like stating that kind of premise? Or would you prefer something like this?
∀p(∃xKxp → p) — Srap Tasmaner
But then, honestly, I'm not sure what there is to talk about if your position is that one can know things that are not so, see things that are not there, remember things that did not happen, and regret doing things you did not do. — Srap Tasmaner

It's very common, I claim to know, see, remember, or regret something, which turns out not to be so. — Metaphysician Undercover
I thought we were discussing what "is true" does, not what "X" (or "the kettle" or "the kettle is boiling") does. — Luke
Here's a link to a post of mine about this. If you clink on that link, it takes you right to what I said. In this context, we could say it refers to what I said. Following that link is how you get the job done of finding out what I said. — Srap Tasmaner
I think that's part of what makes semantic content work through; it holds environmental objects equivalent through how we access them, how they function, and how we expect them to respond to manipulation. — fdrake
For semantic content be informative about an object's state, there must be an association between that object's state and the language about the object. — fdrake
Understanding those functional roles is accurate when it mirrors the developmental trajectories of the kettle, so when someone says "the kettle is boiling", it's true to say that when the kettle is boiling... Because the switch was flipped and the water was boiling etc... Something happened to make it true in context, and the pattern of language tracks the properties through shared expectations of environmental development. The association becomes a causal history of interacting environmental events and language. — fdrake
The causal history; making event-patterns of language co-occur with event-patterns of environments; means both reciprocally inform, and in many use cases reciprocally co-determine - we make our environments navigable and manipulable. — fdrake
Semantic content is then a historically informed behavioural expectation of the environment, whose developmental trajectories are demarcated through current and prior expectations of development. The causes in the present in both language and the world resemble the causes in the past - the former is a criterion of iterability (like the private language argument against privation), the latter is a criterion of publicisability (like the private language argument against the beetle's wiggling being determinative of sense). — fdrake
The causal patterns of language use grow to resemble the environment modulo perceptual individuation. Feedback lets the former and the latter have reciprocal impact; so much so that in many circumstances we can append "I think" to to a phrase, like "I think the kettle is boiling" and convey the same behavioural expectation of the environment but indexed to an agent. But the distinction between the two is precisely useful because the environment's patterns are shared. The causal histories differ, so the behavioural expectations in the environment and in language differ, so the meanings differ. One is true when you think it, one is true when the kettle boils.
The mirroring+coupling of causal patterns of language use and environmental comportment/expectations of development is what sets up the remarkable agreement obtained on whether the kettle is boiling... When it is in fact boiling or not. The causal history of language and environment over time, through constant work and tailoring, becomes discriminative on both environment and language. — fdrake
As with "put the kettle on" above, semantic content doesn't seem to always need to be informative about an object's state. I might not even know of the existence of an object in that expression, so I can't see how my use of the term 'the kettle' could carry information about it's state? — Isaac
. I'm not (yet) seeing how such vague and ephemeral environmental objects can be amenable to analysis of their properties to make "the kettle is black" something which can be eternally, objectively 'true', outside of the language game in which it was used. — Isaac
The barrier still in place against correspondence, though, is the lack of specificity. I only need 'the kettle' to be sufficiently similar in our shared expectations about it to maximally reduce surprise. Too specific a object won't do that, it actually needs to be vague to have a chance of my having unsurprising expectations of it. — Isaac
If I've understood you correctly here, this is similar to what I was saying earlier about the environment constraining what can be said. It sets limits on what will work because regardless of out models of it, it is set out in such and such a way and it's not a homogenous soup which we can make of what we will. There may be a wide range of values which will make "the kettle is boiling" true (in that sense), but they will not be infinite. "the kettle is boiling" won't work given certain environmental constraints. Again, pointing to a rough correspondence, but one insufficiently specific to be amenable to the sorts of truth analysis direct correspondence would seem to need. — Isaac
I think correspondence is one way of looking at it; it really can be that a statement is true because it corresponds to the facts. But I think that for a deflationist this simultaneously says too much and too little. Too much because it doesn't necessarily reflect the T-sentence (can you have a correspondence without a truth? A representational relationships truth preserving? That kind of thing) and too little because it confines the enmeshment of world and declarative language to a particular mode (correspondence). — fdrake
...when someone says "the kettle is boiling", it will occur in a context in which the kettle is individuated from its environment as a distinct site of developmental trajectories, and "boiling" will be inferred from the kettle's current state and developmental trajectory. The former individuation resembles denotation, the latter individuation resembles predication ("... is boiling"). Coupling the association of words with perceptually+pragmatically individuated or demarcated environmental trajectories allows environmental events to be a truth maker for sentences without the former being wholly determined by the latter. — fdrake
Srap is talking about knowing something that is not the case. — Luke
As ↪fdrake states, in an apparently Hume-ian fashion, re: “constant conjunction”, if you say the kettle is boiling, you expect bubbles, which would be the case, for this is at root an analytic judgement. But the tacit understanding the bubbles expected are given by the content of the kettle and not the boiling kettle, immediately makes the statement itself no longer analytic, and thus becomes the source of an illogical inference, and....as we all know....needs awaken one from his “dogmatic slumber”. — Mww
the initial metaphysical question cannot be answered with empirical examples. — Mww
patterns of association in language mirror patterns of association in environments; the histories of the two get intertwined through the mirroring relationship. — fdrake

(1) Semantics in terms of truth conditions, and no analysis of "is true" is possible because of circularity. — Srap Tasmaner
And I almost asked if you felt a little queasy when you reached for words like "tracking" and "mirroring," but it turns out you had something quite specific in mind. — Srap Tasmaner

‘perception is fundamentally the truthful reconstruction of a portion of the physical world through a registering of existing environmental information.’ — Joshs
....and from this well-worn and exceedingly comfortable armchair, a very big thing it is. The solution seems to have become the disregard of metaphysical questions, or at the very least turn them into anthropological/psychological questions. Which is, I must say, “...beneath the dignity of philosophy...”. — Mww
(5) Minor issue. There are differences in intellectual temperament that make your posts difficult for me sometimes. ("You" = fdrake.) You're more "synthetical" and speculative; I'm more "analytical" and -- what's an opposite for "speculative"? Evidence-focused rather than theory-focused? Even with a post like this, I can't help including a folksy example. (Thought maybe I hadn't, but nope, it's right there, end of (3).) Apo said once that I was "too concrete." Analytical me can't ever use words like "enmeshed" or "intertwined" without feeling like I'm cheating. "Enmeshed," to me, is a weasel word -- but it's a perfectly legitimate placeholder when you're model-building! ("These are intimately related, I just can't specify how yet.") — Srap Tasmaner
That's enough. I really want to start all over with this reference and truth stuff, but we'll see. Nothing I've posted so far has gone anywhere. — Srap Tasmaner
I disagree! I think we've come to a better understanding of the discussants' perspectives. Wouldn't've happened without you facilitating it. — fdrake
‘perception is fundamentally the truthful reconstruction of a portion of the physical world through a registering of existing environmental information.’
— Joshs
Not exactly! I don't think it's right (even scientifically) to say that perception always and only aims at accurate representation. That's part of what it does, it has other goals. It is also difficult to distinguish what is accurate from what is useful I think. It'd be a bit shit if we couldn't accurately discern how stuff in the environment behaved - doubt we'd be able to do much, but I don't think that's what perception's "for". — fdrake

I think it may be "eternally" true to say "I boiled the kettle on the 3rd of March 2022", since I did indeed boil the kettle on that day. — fdrake
it's really weird to make statements like "The kettle boiled and I poured cold water from it immediately"/ "The kettle boiled and the water stayed still". You convey an expectation of behaviour and then negate it; the meaning of the sentence part "the kettle boiled" is in conflict with the second bit precisely because the first bit doesn't necessarily fix all the events around it, or which can be embedded in relevant descriptions of causal chains involving it, but nevertheless constrains expectations of other sentence parts. — fdrake
As a rough summary by example, ""the kettle is boiling" is true" makes sense at its level of descriptive granularity because: ( 1 ) the definite article "the" picks out a specific kettle in the environment ( 2 ) that kettle is individuated from its environment by parsing it into salient objects with distinct patterns of behaviour ( 3 ) "is boiling" states a type of environmental pattern the kettle partakes in ( 4 ) under our level of demarcation, it's "only" the kettle that could boil, not the electrical currents or the plug socket despite both partaking in the boiling process ( 5 ) the kettle exhibits the parsed expectations which constitute (somewhat fuzzily!) boiling ( 6 ) that makes "the kettle is boiling" true. — fdrake
