Truth-Evaluable Content
For those
who haven’t read the previous posts, I repeat the first two sentences of the
last one: This series of posts
about contextualism (or “occasion-sensitivity”) was inspired by Sanjit
Chakraborty’s request that I say more about what I call the “truth-evaluable
content” of sentences on occasions of utterance. Formulating what I want to say
in response led me back to Davidson’s “A Nice Derangement of Epitaphs” (NDE), a
paper I discuss for its own sake as well.
(I strongly
recommend you read the previous three
posts, starting with June 2nd’s.)
As I argued in the
previous post, the question as to the nature of meanings shouldn’t be
understood an ontological question (what sort of object is “a meaning”), it
should rather be “What information should a good semantic theory provide about
the words and constructions of a language?”
Davidson agreed with
this throughout his career. Moreover, although I do not agree with his identification of truth-evaluable
content and meaning (see previous post, again), I think that NDE does contain a reasonable answer to the similar
question [in my terminology rather than Davidson’s] about “truth-evaluable
content”,viz.,”What information should a good semantic description of the truth-evaluablecontent
of an utterance on a particular occasion provide?”
Davidson’s answer is
that a good description of the truth-evaluable content of the sentences that
are uttered on a particular occasion is nothing more or less than a “passing theory”
(which has the form a a Tarskian truth-theory) for those sentences and the indefinitely
large totality of sentences that can be derived from them by the familiar recursive
devices.
MY QUESTION ABOUT DAVIDSON: The
truth-evaluable content of a sentence on a particular occasion is, then,
given by its truth-condition, as specified by a passing theory that does WHAT?
One might expect
Davidson to answer, “that describes tacit (implicit) knowledge of the speaker
concerning his or her own words, but Davidson rejects this (as do I, but for
different reasons, which I will give in the next post). Instead, he says that
the passing theory in question must “model the speaker’s competence”.
Davidson’s reasons are stated briefly:
“To say that an explicit theory for interpreting a
speaker is a model of the interpreter’s linguistic competence is not to suggest
that the interpreter knows any such theory. It is possible, of course, that
most interpreters could be brought to acknowledge that they know some of the
axioms of a theory of truth; for example, that a conjunction is true if and
only if each of the conjuncts is true. And perhaps they also know theorems of
the form ‘An utterance of the sentence ‘‘There is life on Mars’’ is true if and
only if there is life on Mars at the time of the utterance.’ On the other hand,
no one now has explicit knowledge of a fully satisfactory theory for
interpreting the speakers of any natural language. In any case, claims about
what would constitute a satisfactory theory are not, as I said, claims about
the propositional knowledge of an interpreter, nor are they claims about the
details of the inner workings of some part of the brain. They are rather claims
about what must be said to give a satisfactory description of the competence of
the interpreter.” [NDE 256]
But this doesn’t tell us what “modeling
competence is”; it only tells us that it isn’t
describing either knowledge or brain-machinery.
