    It's something like a stratum of human behaviour which does the revealing, isn't it? And it's inflected by norms but not totally determined by them.fdrake

    When I was a kid, we used to set the table for dinner, always the same way: on the left, fork, sitting on a paper napkin, on the right, knife and spoon, in that order, dinner plate in between, and all on a placemat. That was our custom. There's logic to it, but it could clearly be done other ways, and was done differently in other homes. There's also a more general norm here, of which we had a specific version, of having silverware for everyone on the table. That too has a logic to it, but needn't be done, much less done this way.

    And we could keep going, with more and more general norms that underlie specific ones. But is eating -- rather than eating specific things in specific ways at specific times of day -- is that "just" a norm?

    You could say yes if you intend to sweep in everything a human attaches value to; you could make eating a biological norm, so to speak. But we're no longer talking about custom or convention. There is nothing arbitrary about eating. (But it is "optional" if you value something else more highly than your own life, so still arguably a "norm" in some broad sense.)

    So I'm just a little leery of a story that's "norms all the way down." The argument that we just happen to say "red" instead of "rouge" for "merely" historical reasons, how well does that extend to eating? If your history takes in the rise of multicellular organisms, which happen to be things that eat, maybe. But to make sense of that, we'd have to look at norms of conversation.

    Now what about truth? There are old arguments for and against "truth by convention" that I don't want to rehash. Nor do I want to talk about what people think truth is; for one thing, it's part of the idea of truth that what people think isn't necessarily it. But I do think there's room to talk about the experience of truth, so that's what I've been trying to make a start on here.

    We're asking about a hypothetical world in which there are no people doing things with words. This is where the distinction between "truth at" and "truth in" is important.

    Obviously we are using the English language to describe this hypothetical world but then also obviously there is no English language in this hypothetical world. You seem unwilling to make this same distinction when discussing propositions and truth, as if somehow they're special entities very unlike the English language.

    Sure, there is no English in that hypothetical world. But there is gold. That's the way it is set up, in the wording 'and nothing else changes". The alternative is to deny transworld identity, which is an option open to you. You would have few companions if you did so.

    I have only ever claimed that because there is no language in that hypothetical world there are no propositions in that hypothetical world and so no true propositions (truths) in that hypothetical world.

Hence you want to say that "there is gold in those hills" is not true in a world in which there is gold in those hills, but no one to say it.

    I think we've had this discussion before. But we might as well have it again to see if we end up somewhere else than last time. It's an enjoyable one to have with you though. I am going to make liberal use of scarequotes so that I can highlight placeholders and weasel words.

    I'm tempted to bite the bullet and say yes, eating is "just" a norm, but in a qualified sense. Human behaviour regarding eating is incredibly flexible in a way the necessary and sufficient conditions for counting as eating aren't. I don't really want to say "necessary and sufficient conditions", but let's just leave it there for now. Eating is "the ingestion of food". So if something counts as the ingestion of food, it counts as eating. But that's not quite all there is to the story, is it? Because that might appear to make eating "about" our words for it. Whereas we use the word eating because things in fact do eat.

    What I want to say is that things eat in the same sense as they walk, run, dance, skip, speak, interpret... All of those things. There's different degrees of ambiguity in the coordinating norms for what counts as each, which "couple" with different ranges of stuff in the "corresponding" category. Dancing events count as dancing. Eating events count as eating.

    But we're no longer talking about custom or convention. There is nothing arbitrary about eating.

    So yes, I agree with this, we're no longer "just" talking about custom or convention. But I want to stress that I never was just talking about them, and I don't think custom or convention are "just" custom or convention either. As in, if you join the Masons, you really have joined the masons. "fdrake joined the Masons" would be true or false.

    Where I think we differ, at least in respect to your above post, is that you construe custom and convention as a different type of thing than eating, whereas I see them as the same type - flavours of event that have repeating patterns. If we think about coordination as having a "map" and a "territory" as we'd ordinarily expect a representation to behave like, the representation being the map and the represented being the territory - there's no neat correspondence between those in how I see it. The "map" is event sequences of human behaviour, and the "territory" is event sequences of arbitrary types of thing. And then you've got to ask where the types come from in both, right?

    I do think "where the types come from in nature and norm" is a very different question than "under what conditions are sentences true", and a slightly different question from "where does the correlation between nature types and norm types come in". I hope that I can talk about the latter without talking about the former two at this point. That is, take that there are such patterns in nature and norms for granted, and wonder how they might come to couple.

    I only have toy examples about this, they're from maths rather than nature, but I hope they are illustrative. I was teaching division by 2, with remainder. I got my student to divide the following numbers by 2:

    {1,2,3,4,5,6,7,8,9,10}

    and record the quotient and remainder

    remainders={1,0,1,0,1,0,1,0,1,0}
    quotients={0,1,1,2,2,3,3,4,4,5}

    I then asked the student to say the sequence of remainders aloud, after I'd said the number. So:

    fdrake: 1, student: 1
    fdrake: 2, student: 0
    fdrake:3, student 1
    ...

    and so on.

    I then asked the student to consider how the sequence might go on. They grokked that it would be alternating 0s and 1s. So they inferred the rule:

    "if fdrake just said n, and I said 0 for n-1, say 1. If fdrake just said n, and I said 1 for n-1, say 0", and they could do this arbitrarily.

    That's then a particular function which maps natural numbers to their remainder when divided by 2. But it's recited as a sequence of pairs by the student and I, in which I say a number and the student follows the rule.

    What we'd thus done is constructed something that counts as the mapping of naturals to their remainders when divided by 2, and what counted as that mapping was our sequence of pairs of vocalisations.

    What inculcated the norm in my student was asking them how the sequence might go on, which set up an expectation for what they should do given what I do. They thus could interpret my vocalisations as an imperative for them to utter the next number in the pattern. They would not have experienced them as an imperative without my role as their tutor (giving me some kind of legislative power over their behaviour), or me asking them to continue the pattern. Which they could then do as a distinct idea afterwards. They experienced the "should" I created as a mapping between two things.

    I think that smells a lot of an expectation in a probability sense, the student had figured out that they'd get the answer right if they alternated, so they'd been given an imperative to minimise deviation from the expectation I provided with corrections or encouragement... Which starts looking a lot like a probabilistic inference procedure with entropy minimisation. Which is something we know human bodies do all the time.

    So I would be really surprised if our bodies abilities to do our homeostatic minimisation of variation wasn't leveraged like hell in our ability to coordinate behaviour and create norms. Since, as I claimed earlier, norms behave a lot like expectations. And correlations are another type of expectation.

    That's about how I see it. We end up having coordinating norms through our ability to arbitrarily contextualise things, but then constrain that arbitrariness with expectations. Then we can learn how those constraints work by minimising deviations from token examples which are "generic" in some sense
    *
    (by generic I mean generated in accordance with the target pattern)
    . Which comes with a considerable degree of flexibility of rules you can learn from a given pattern, but it's no longer arbitrary, since we've put some tokens into the type creating engine that it must include and create a function for.

    And that function is a recipe for recognising tokens and mapping them to other tokens - which we then enact to varying degrees of success {we do stuff which counts as an attempt to follow the pattern}. If the degree of success of the enactment is sufficiently high, that means counting as doing the thing which counts as the generating pattern. Which sets up the correspondence between our behaviour and the generating pattern as a type of association. Which is then the appropriate type in context.

    In the above case, the student had learned the alternating pattern because they said the right things. Where "right things" is what is expected given the pattern and the imperative to reproduce it.

    So how does this relate to truthbearers? Well it's not like a sentence in this view even has propositional content in the sense we'd ordinarily consider - it has conditions under which it is correctly assertible, which is already some normy thing. And a "model" where the sentence is true in the extensional semantics sense is more like a context - of stuff, norms, events, blah - in which it is correctly assertible.

    I would like to have my cake and it it too, and claim that those contexts can be very object oriented and have exact constraints in them - like the maths example above. The student could say things which were true or false strictly, rather than stuff which counts as true or false for some purpose {like just a posit or a belief or a framing assumption}. And by "strictly" there I mean there being a unique "right" answer {any exemplar of a set of equivalent answers which count as that unique answer...}.

    It's not, and I'm sorry you can't see the difference between an utterance and a proposition. Chess is constructed by us using words and wood. When you look at a chess board, do you only see the wood? or can you also see Alekhine's Defence? In a world without wood, can there be no chess? But this has already been addressed; as it stands we are simply rehashing stuff that has already been dismissed.

    This, I believe, is your original claim, a response to a post of mine.
    So the claim is that when all life dies out there will be gold in Boorara but no truths or falsehoods because there will be no propositions.Michael
    The consequence of what you have said here is that there is gold in Boorara and yet it is not true that "There is gold in Boorara". This is at odds with [there is gold in Borrara ≡ "There is gold in Boorara" is true]. Perhaps the error is to think that all there is to a proposition is an utterance. But we dealt with that earlier. I'll repeat that 1+1=2, giving a new utterance of the very same assertion as was used earlier. There is something different about this utterance, but there is also something that is the same.

    Or is it that the antecedent "there are no propositions" is a misconstruel? It is clear that there are propositions, including those that set up the world in question.

    Again, a rehash of stuff already considered.

    There might be something else that is used other than wood but so far you haven't offered any replacement for language that allows for propositions in that world.

    At the moment your position is akin to saying that there is chess in a barren world, and I'm the one saying that there isn't – that there is chess in a world only if there are people (or computers) in that world playing chess.

    It is clear that there are propositions, including those that set up the world in question.Banno

    We are using language and propositions to talk about that world, but there are no languages or propositions in that world.

    You continue to equivocate.

    Try reading the section on Truth in a World vs. Truth at a World again. As a very explicit example it offers:

    A proposition like <there are no propositions> is true at certain possible worlds but true in none.

    If "there are no propositions" is true at World X then there are no propositions in World X, just as if "there is no English language" is true at World X then there is no English language in World X.
