Abstract ( 19.0: how to describe "brief")
Abstract:
Recall
the spirit of quantum language
( i.e.,
the spirit of the quantum mechanical world view),
that is,
$(\sharp):$ 
every phenomenon should be described by quantum language
(
knowing it is somewhat unreasonable
)!

Thus, we consider that
even the "belief" should be described in terms of quantum language.
For this,
it suffices to consider the identification:
$$
\mbox{
"belief"
$=$
"odds by bookmaker"
}
$$
This approach has a great merit such that
{the principle of equal weight holds}.
This chapter is extracted from Chapter 8 in
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.
