  The Einstein, Podolski and Rosen (EPR) argument aiming to prove the
incompleteness of quantum mechanics (QM) was opposed by most EPR's contemporary
physicists and is not accepted within the standard interpretation of QM, which
maintains that QM is a complete theory. An analysis of the semantic
implications of the opponent positions shows that they imply different notions
of truth. The introduction of a nonclassical notion of truth within the
standard interpretation is usually justified by referring to known theorems
that should prove that QM is a contextual and nonlocal theory. However, these
theorems are based on a doubtful implicit epistemological assumption. If one
renounces it, one can provide an alternative interpretation of QM that it
realistic in a semantic sense. Within this interpretation the EPR viewpoint is
recovered and QM is considered a (semantically) incomplete, noncontextual and
local theory. Furthermore, the new interpretation provides several suggestions
for constructing a more general theory embedding QM and for connecting QM with
classical physics and relativity.
