In this chapter,
we discuss the relationship more systematically.

Again recall that, as mentioned in $\S$1.1, the main purpose of this book is to
assert the following figure 1.1:
Fig.1.1: the location of "quantum language" in the worldviews
This(particularly, ⑦⑨) implies that quantum language has the following three aspects:
$$
\left\{\begin{array}{ll}
\mbox{ ⑦ :the standard interpretation of quantum mechanics}
\\
\mbox{
$\qquad$
(i.e., the true colors of the Copenhagen interpretation)
}
\\
\\
\mbox{ ⑧ :
the final goal of the dualistic idealism (Descartes=Kant philosophy)
}
\\
\\
\mbox{ ⑨ :
theoretical statistics of the future
}
\end{array}\right.
