plausible syntactic theories.
Objections to the Davidsonian version
Objection 1
Like the Verification Theory, the Truth-Condition Theory seems to apply
only to descriptive, fact-stating language; questions and commands and so
on are not true or false at all.
A weak reply
Although we do not ordinarily call questions or commands "true" and "false,"
they do have bipolar, truth-like semantic values. A question is correctly
answered "yes" or "no"; a command is obeyed or disobeyed. Intuitively, a
nondeclarative sentence corresponds to a state of affairs that may or may
not obtain, even though its function is not to describe or report that state
of affairs. And for semantical purposes we may as well treat those semantic
values as truth-values. For example, a command is "true" if it does in fact
go on to be obeyed, "false" if it does not. Of course this is a nonstandard
use of "true" and "false"; we are widening their application to all semantic
bipolarity
