Thanks to R. Paul for the quote:
"to say
'..."it is true that Caesar was murdered" means no more than that Caesar was
murdered, and "it is false that Caesar was murdered" means that Caesar was
not murdered.'
[Symposium: Facts and Propositions, F. P. Ramsey; G. E. Moore,
Proceedings of the Aristotelian Society, Supplementary Volumes, Vol. 7, Mind,
Objectivity and Fact. (1927)*, pp. 153-206.]
Exactly. I suppose that essay _was_ repr. in "Philosophical Papers" and
other essays, posthum. ed. by D. H. Mellor. (1900 repr. -- . Indeed from
wikipedia,
_http://en.wikipedia.org/wiki/Redundancy_theory_of_truth_
(http://en.wikipedia.org/wiki/Redundancy_theory_of_truth) :
"The theory is commonly attributed to Frank P. Ramsey, who argued that the
use of words like fact and truth was nothing but a roundabout way of asserting
a proposition, and that treating these words as separate problems in
isolation from judgment was merely a "linguistic muddle", though there remains
some
debate as to the correct interpretation of his position (Le Morvan 2004)."
The wikipedia article goes on to quote some more passages from Ramsey's
seminal -- and largely ignored -- essay. It was revived by Strawson/Grice and,
in
the USA, by pro-sententialism.
"But before we proceed further with the analysis of judgment, it is necessary
to say something about truth and falsehood, in order to show that there is
really no separate problem of truth but merely a linguistic muddle." (Ramsey,
1990 reprint, p.38).
Why Ramsey may not have said 'vacuous', he does say "superfluous" -- hence
_redundancy_.
"This may perhaps be made clearer by supposing for a moment that only one
form of proposition is in question, say the relational form aRb"
or as I prefer, the S is P, or the alpha is beta.
"then 'He is always right' could be expressed by 'For all a, R, b, if he
asserts aRb, then aRb '"
or, as I'd rewrite this:
"For all S, P, and copula, if Tom says, The S is P, then the S is P."
Ramsey continues:
"to which 'is true' would be an obviously superfluous addition. When all
forms of proposition are included the analysis is more complicated but not
essentially different; and it is clear that the problem is not as to the
nature of
truth and falsehood, but as to the nature of judgment or assertion, for what
is difficult to analyse in the above formulation is 'He asserts aRb ' It is,
perhaps, also immediately obvious that if we have analysed judgment we have
solved the problem of truth; for taking the mental factor in a judgment
(which is often itself called a judgment), the truth or falsity of this
depends
only on what proposition it is that is judged, and what we have to explain is
the meaning of saying that the judgment is a judgment that a has R to b, i.e.
is true if aRb, false if not. We can, if we like, say that it is true if
there exists a corresponding fact that a has R to b, but this is essentially
not
an analysis but a periphrasis, for 'The fact that a has R to b exists' is no
different from ' a has R to b '.

History of Philosophy 12(4), 705–718.

Propositions'", Dialectica 58(4), 499.
---- I disagree with Ramsey that bringing in _judge_ is going to shed any
light, but it's worth the try.
Grice discusses his former student (Strawson)'s theory in the "Truth"
section in "Further notes on logic and conversation", now in WOW, Studies in
the
Way of Words. He mentions a few cases that the 'performatory' theory (as
Strawson's is sometimes called) may find some difficulty in getting rid of --
such
as:
"All that the policeman said was true"
-- We see above that Ramsey did not find that troublesome.
Note that Ramsey is taking a relational form of propositions R(a, b), which
is perhaps just as well. My canonical proposition, though is,
iota operator x. alpha x & beta x
-- the A is B, or the S is P -- but perhaps Ramsey is _righter_.
Redundantly yours, I remain your superfluous servant.
