Actually, there are several theories of truth - the most common are the
correspondence theory, the coherence theory, and the deflationary theory.
Tarski asserted that truth is just the assertion of the sentence that is
true (snow is white iff "snow is white" is true). This is called
Convention T, and it is this that Popper appealed to. A more recent theory
is the "revision theory" that a sentence is true if any logical revision
results in it being true in that arbitrary model.
There are others. Check out the online Stanford Encyclopedia of Philosophy:
