In logic a statement can be
the assertion that is made by a true or false declarative sentence... a statement is viewed as a truth bearer
However, in everyday speech a statement is
a definite or clear expression of something in speech or writing
So I wondered whether a statement in this logical sense can be indefinite or unclear, especially whether it is true or false, and how to state that uncertainty.
So Ezra Pound's Pisan Cantos states that
Manes was tanned and stuffed
It's not clear to me what sense of 'tanned' is meant here. I think that it is not a clear expression, and we can't be sure what sort of logical statement is being made.
However, some sentences use relatively clear and unambiguous language but seem to express a statement that is an indefinite or unclear as a truth bearing thing. So e.g. when Pound says that
He strove to resuscitate the dead art / Of poetry
I think he's asserting something vague. Is there a way of speaking about statements of this sort, which often seem to have emotive and symbolic uses. Similarly, it is easy to construct a metaphor that literally speaking seems to have indefinite truth conditions:
He played the violin of death.
The metaphorical meaning is clear: death is compared to an orchestra someone is playing in. But I have no idea what would mean we should agree or disagree with it.
