1. Davidson's principles (1) - (3) are a good description of lexical meaning.
2. Davidson's argument shows that (1) - (3) cannot account for linguistic behavior.
Therefore
3. We lose nothing by giving up the idea of lexical meaning. — Srap Tasmaner
This looks like a pretty good summary to me. Here's a key question:
What's the relationship between "first/literal meaning" and "lexical meaning"?
Davidson doesn't really address this directly, but I think there's a difference, here. First meaning is defined by the interplay of prior and passing theories, and - I think - "lexical meaning" would be part of the prior theory, but it wouldn't be it's entirety, because "lexical meaning" remains some sort of super-situational ideal, an abstraction.
Take this section where he looks at whether a prior theory could be what we think of a natural language.
An interpreter’s prior theory has a better chance of describing what we might think of as a natural language, particularly a prior theory brought to a first conversation. The less we know about the speaker, assuming we know he belongs to our language community, the more nearly our prior theory will simply be the theory we expect someone who hears our unguarded speech to use. (262)
I think there's an idea implied here, that the more we interact with specific people, the more we modify the prior theories we bring to conversations with them, but they don't impact "the theory we expect someone who hears our unguarded speech to use". It feels like a natural language is something a prior theory will diverge from the more we interact with a particular person. Or in short, that we expect Mrs. Malaprop to make malapropisms is part of the prior theory we bring to a conversation with Mrs. Malaprop, but it doesn't modify what we think of as a "natural language".
But he doesn't really talk about what it is he thinks of as "natural language". He keeps saying things like "in rather unusual ways" with the assumption being that there's a "usual" way we all think of language that's obvious.
And this is where I'll again have to emphasise that I come at this article from a linguistic perspective and not a philosophical one; maybe in philosophical traditions there actually
is such a thing, and I just don't understand it. So I have this megpie mind; I snatch what's useful from philosophy and discard the rest. Linguistics basically started in earnest as a discipline with Saussure, and it turned into a systematic description of language, where signs interact with each other to make for a whole structure. Since early linguistics was tied up with anthropology, one way to look at it is to find a formal way to describe human artefacts. In other ways, lingistists aren't really doing anything that avarage language users aren't; they're just more systematic and ask questions that arise from being more systematic.
That's never been quite enough to account for all data, though, so linguists would look towards the philosophy of language, say Wittgenstein's language games, Austin/Searle's speech acts, and Grice's co-operative principle, and also towards linguists such as Jakobson and his functions of language, and would establish a discipline called pragmatics, so that we now have:
[Syntax, morphologly, phonetics, phonology, semantics] describe language, and pragmatics describes how people use language.
That was the mainstream standard organisation when I went to university in the 90ies, but pragmatics wasn't actually fully established, I think, until the early 70ies.
Then there's another distniction: linguistic analysis can be twofold: synchorony and diachrony. How language is used at any one time, and how language changes. Usually a synchronic approach would describe a fairly rigid set of rules, and a diachronic approach would then show how rules are broken, subverted, played with, so that langauge changes. (An example would be the migration of the "n" from the noun proper to the indefinite article "a": a nadder -> an adder; a napron --> an apron). Those approaches are seen as complementary, so a described, more or less rigid set of rules isn't taken to determine actual language behaviour.
So one problem I have is that my intuition seems to clash with Davidson's. I might agree with a lot of things he's saying, but I might never have held his view of what a natural language actually is. For example, I think one difference between my instinctive approach and Davidson's might be the following:
We both see language as an overly rigid structure. But where he expects language rules to determine behaviour (something he doesn't find in real life), I expect that rigid structure to be some sort of ideal type of a structuring principle; something people use to both create utterances and compare other people's utterances to, and something that will on occasion fail: people make mistakes, people don't find the words to express what they want to say and approximate with the best words they can find (and on failure to communicate try alternate ways of expressing themselves)... and so on.
It's not a surprise to me that you can also play with language. And we can learn by playing. For example, there's this little tale,
"Ladle Rat Rotten Hut", which was written to demonstrate the importance of intonation to interpreting words (it's a rewritten version "Little Red Riding Hood"; sadly the audio link seems to be broken - the story's meant to be both read and heard.
Here's a youtube link.) It's the perfect case for a passing theory, too. And it's also clear why the theory will remain a passing theory (but maybe turn into a prior theory for whenever you engage with the same text again). None of these new words we'd expect to spill over into dialect, though they might spread as in-jokes for an in-group.
I actually meant to be briefer and more concise this time round.
Basically, I think Davidson is saying that prior and passing theories establish first meaning, which in turn can have consequent meanings due to the compositionality of language (to understand the Shakespear sonnet, we must first understand "foison" and "tire"). What "first meaning" has in common with "lexical meaning" is that it's not necessirily identical with the intended meaning; where it differs is that, unlike "lexical meaning", "first meaning" is always situational. And the way Davidson analysis first meaning sheds doubt on "lexical meaning", though it's possible to import "lexical meaning" into a speaker's prior theory.
So when he finishes with these words:
And we should try again to say how convention in any important sense is involved in language; or, as I think, weshould give up the attempt to illuminate how we communicate by appeal to conventions. (265)
I think, the first clause is his conclusion, and the second clause his bias.
I think he's largely right, but I'm not sure I understand what he thinks a natural language is supposed to be, and I think we (Davidson and I) start in completely different places on that topic, which is why I have trouble reading him in detail.
