  In this paper I present and defend Rovelli's relation quantum mechanics from
some foreseeable objections, so as to clarify its philosophical implications
vis a vis rival interpretations. In particular I ask whether RQM presupposes a
hidden recourse to both a duality of evolutions and of ontology (the
relationality of quantum world and the intrinsicness of the classical world,
which in the limit must be recovered from the former). I then concentrate on
the pluralistic, antimonistic metaphysical consequences of the theory, due to
the impossibility of assigning a state to the quantum universe. Finally, in the
last section I note interesting consequences of RQM with respect to the
possibility of defining a local, quantum relativistic becoming (in flat
spacetimes).Given the difficulties of having the cosmic form of becoming that
would be appropriate for priority monism, RQM seems to present an important
advantage with respect to monistic views, at least as far as the possibility of
explaining our experience of time is concerned.
