Right. You might call the system of only logical axioms "the empty
theory" or "the null theory" -- it's just validities, no contingent
formula are provable or refutable.
I know what you mean by that, but personally I wouldn't use the
terminology 'empty theory' since the theory, which is a certain set of
sentences, is not the empty set.
Well, it's empty of non-logical axioms. :)
