  According to one possible diagnosis of the quantum measurement problem, it is
a consequence of quantum fundamentalism claiming that ontology and epistemology
of the world are exclusively quantum, and classical physics is only an
approximation. For N. Bohr, the measurement problem is a pseudo-problem because
any quantum phenomenon presupposes the classical context of an experimental
setup and the use of classical concepts to describe it. We consider Bohr's
position from the point of view of our contextual quantum realism (CQR),
inspired by the later Wittgenstein philosophy. Our approach is consistent with
H. Zinkernagel's interpretation, according to which Bohr's position is not only
epistemological anti-fundamentalism, but also ontological anti-fundamentalism.
