  The aim of this paper is to present an analysis of the new theorem by Pusey,
Barrett and Rudolph (PBR) concerning ontic and epistemic hidden variables in
quantum mechanics [Nature Phys. 8, 476 (2012)]. This is a kind of review and
defense of my previous critical analysis done in the context of Bohmian
mechanics. This is also the occasion for me to review some of the fundamental
aspects of Bohmian theory rarely discussed in the literature. The paper is
submitted for the issue PBR theorem and Beyond of IJQF (International Journal
of Quantum Foundations).
