  Recently we proposed the linguistic interpretation of quantum mechanics
(called quantum and classical measurement theory), which was characterized as a
kind of metaphysical and linguistic turn of the Copenhagen interpretation. This
turn from physics to language does not only extend quantum theory to classical
systems but also yield the quantum mechanical world view (i.e., quantum
philosophy or quantum language). The purpose of this paper is to formulate the
double-slit experiment, the quantum eraser experiment, Wheeler's delayed choice
experiment, Hardy's paradox and the three boxes paradox (the weak value
associated with a weak measurement due to Aharonov, et al.) in the linguistic
interpretation of quantum mechanics. Through these arguments, we assert that
the linguistic interpretation is just the final version of so called Copenhagen
interpretation. And therefore, we conclude that the Copenhagen interpretation
does not belong to physics (i.e., the realistic world view) but the linguistic
world view.
