-- Tarski, the Polish philosopher and logician, is often misquoted -- but then he wrote in Polish. Apparently, his most popular, "The semantic conception of truth" is NOT where to look for the Convention T that Davidson popularised. This came from a longer essay by Tarksi, etc.

J. writes:
[For Tarski]: ""Louis XVI was beheaded" iff Louis was, in fact, beheaded (recalling Quine vaguely on this chestnut). So the object language is in " " and the metalanguage, the extra-linguistic perception, like...an event, without the " ". Then the..so what? He doesn't at all show how the object-phrase relates to the meta/perception, does he. semantics-- like philosophy sans metaphysics. It may work for code, but it's not really a proof of any sort, IMHE."

Indeed.
Incidentally, I suppose Grice was trying to be _clever_ (which he was, but you can still try -- right?). I don't think I've found in all his opus (as opposed to every other sentence by Tarski, Davidson, etc.) along the lines:
"Snow is white" is true iff snow is white.
Or

But I should have to revise that.
Consider, -- sorry about that! --
"Fido is shaggy".
This Grice claims stands for something pretty complex.
Notably,
"shaggy" means 'hairy-coated'.

I would think that a Tarskian would rather have concentrated on disquotional contexts alla:
"Fido is shaggy" iff Fido is shaggy.
----
Incidentally, 'shaggy' is of course a metaphor, and thus a Conversational Implicature. Fido is _not_ a shag, which is a noun meaning wool-material. Still, Fido not _literally_ 'shaggy'. Rather, Fido is, as Grice correctly indicates, 'hairy-coated'.
In fact, all dogs are!
