We have a more than 3000year history concerning the research of worldviews. And this study has been always located at the central position of science and philosophy.
The first paradigm shift (i.e., the leap from "the animistic worldview (life dwells on things) " of the Middle Ages) is the mechanical worldview, which was owed to Galileo, Bacon, Descartes, Newton, and so on. This paradigm shift is very powerful, and hence, it opened the door from the Middle Ages to the Modern Ages (see ① in Fig.1). Here, the mechanical word view is characterized as.
(A): Study every (nonphysical) science, modeled on physics.
It is simple, but, as the norm of the best description of the world, it has dominated the modern science until today.
If it be so, everyone may dream to propose the scond paradigm shift, however, it may not be easy. In fact, it is not difficult
to enumerate shattered dreams such as catastrophe theory, fuzzy theory, complex system theory, chaos theory and so on. However, It is not stopped that
we strive against instinct of liking to tell "grand narratives". That is, we cannot stop to investigate the paradigm shift.
Here we assert that the linguistic worldview in Fig. 1 due to the quantum language (=measurement theory),
which is the final stage of the linguistic series in Fig. 1, is the scond paradigm shift.
§ 2 The beginning of things: Heisenberg's uncertainty principle
Our starting point is the discovery ( 20 years ago) of the mathematical formulation of Heisenberg's uncertainty principle (cf. ref. [1]).
This discovery urged us to investigate the following problem:
(B):
What is quantum mechanics?
Or, what is the standard interpretation of quantum mechanics?
Quantum mechanics has various interpretations ( such as the Copenhagen interpretation, the many worlds interpretation, etc.). This fact may be negligible in applications. But it is serious for the formulation of Heisenberg's uncertainty principle. That is, the "errors" depend on the interpretation
(e.g.,
the wavefunction collapse is accepted or not?)
).
Thus,
we now think that we should have argued about Heisenberg's uncertainty relation under a certain firm interpretation of quantum mechanics in ref. [1].
§ 3 In the beginning was the word  the miraculous power of language 
Quantum mechanics was born about 90 years ago. However, we may be possessed with the surprising prejudice. That is, we may convince "Quantum mechanics is physics."
Writing the conclusion first, we say that the linguistic worldview (i.e., the in Fig. 1) is,
(C): 
In the beginning there exists the language called "quantum language". And world is described and constructed by the language.

(cf. Refs.[2, 3]). Although the explanation of quantum language is omitted here,
it suffices to consider that it is composed of two spells (concerning "measurement" and "causality") and the linguistic interpretation.
What we can do in quantum language (=measurement theory) is only to trust in man's linguistic competence.
Fig 1 says that quantum language has the following three aspects:
[⑦ Fig 1]:
The ture colors of the Copenhagen interpretation. That is, the Copenhagen interpretation does not belong to physics!
(Even if "the true quantum mechanics" exists in the direction of ⑤, I believe that it is the relativistic quantum mechanics that does not need "interpretation")

[⑧ Fig 1]:
The final goal of the dualistic idealism ( Descartes=Kant philosophy)

[⑨ Fig 1]:
Theoretical statistics of the future

This language has a great power to describe ordinary phenomena as well as quantum phenomena. For example, economics is created by describing economical phenomena in quantum language.
Also,

economics is created by describing economical phenomena in quantum language.

quantum mechanics is created by describing quantum phenomena in quantum language.

psychology is created by describing psychological phenomena in quantum language.

(see Fig 2).
We assert that this is the true picture of quantum mechanics, and we are convinced that this is just the answer to the question (B).
Therefore, the "⑦ →" in Fig. 1 is a historical circumstance. and thus, the true direction is the "← ⑦"(where we consider the usual quantum mechanics and not the quantum physics beyond the ⑤ in Fig. 1).
That is,
(C)=[Fig.2]=(D), namely,
(D): 

Thus, the linguistic worldview (C) (= in Fig. 1) asserts that
 Science (more precisely, nonphysical science) is to describe the world by quantum language.
Therefore,

the metaphysics called quantum language is located in the center of science.
Again note that the linguistic worldview (C) (= in Fig. 1)is due to the great human's power of linguistics.
If quantum mechanics is regarded as physics, we cannot understand the reason that there are several paradoxes and interpretations in quantum mechanics.
For example, we think that Schrödinger's cat does not live in the linguistic worldview since it can not be described by quantum mechanics.
(Recall Wittgenstein's saying: "The limits of my language mean the limits of my world"). Also, we consider that the dualism is not fit for physics.
Such idea is not only due to us but also Einstein, who never regarded quantum mechanics as physics.
§ 4 Mechanical worldview (A) vs. linguistic worldview (C)
For example, some philosophers has been studying "Achilles and the tortoise (cf. the above (D))" during about 2500 years. If you think that they are too stupid to understand the geometric series,
you are an ordinary person, i.e., the believer of the mechanical worldview (A).
That is, you do not know that the philosophers has been making efforts to discover another
worldview rather than the mechanical worldview (A) (cf. [11]).
Also, under the mechanical worldview (A), we cannot answer the question "What is statistics? or
"What is (nonphysical) spacetime?" That is, the quantum language is necessary
to answer these questions (cf. [79, 1214]). Moreover, we cannot understand the dualistic idealism (in the main stream of the philosophy)
without the linguistic worldview (C) (cf. [4,14]).
This is the reason that there are no understandable books concerning dualistic idealism.
Since unsolved problems are easily solved under the (C), we believe that the linguistic worldview (C) is superior to the mechanical worldview(A).
Also, it should be noted that the mechanical worldview (A) has no room in Fig. 1.
Thus, it is improper to consider the mechanical worldview (A) as a kind of worldview.
Dr. Hawking said in his best seller book [A Brief History of Time: From the Big
Bang to Black Holes, Bantam, Boston, 1990]:
(E): 
Philosophers reduced the scope of their inquiries so
much that Wittgenstein the most famous philosopher
this century, said "The sole remaining task for philosophy
is the analysis of language." What a comedown
from the great tradition of philosophy from
Aristotle to Kant!

We think that this is not
only his opinion but also most scientists' opinion.
However, we do not agree to his opinion, since we know the development such as "Kant ⇒ Wittgenstein ⇒ The linguistic worldview " in Fig. 1.
§ 5 The end of grand narratives  3000year final answer 
Now we believe that the proof of "the ⑩ in Fig. 1" has been almost completed.
Therefore, the countdown of the two ends of grand narratives (⑤ and ⑩ in Fig.1) started.
In the above sense (i.e., the linguistic series acquires the linguistic worldview (C)), we dare to
declare
"the happy end of grand narratives"
However, science has already rushed into post modern time[=the ages of small narratives = the ages of sciences(i.e., engineering, social sciences,
bio, etc.) in (D)]. Thus, we think that science is not over.
