Site Name History
SRFL has uploaded the papers on language universals since 2003, when the site name was using sekinan.org.
Now its name is not adopted by not-using the self-managed website.
From 2014, I have mainly used Weebly site titled Sekinan initials. So crowned Sekinan sites contain mainly early papers and essays although being renewed appropriately. Also I have used Wix site for invitation being named SIL initials.
But the papers have gradually increased. In 2016 I have newly used Webnode site for the reason storing up more papers easily. Webnode sites are titled mainly SRFL initials, which papers are from Middle to Present.
Besides Weebly and Webnode, I have used Website, Site 123 for simplified and invitational sites, so these sites are almost Modern papers and essays and understandable invitation articles to the study of language. Contained papers are rather few but probably more readable, especially to the first visiting learners of language problems, naming is ENSILA for Website and Sekinan for Site 123.
Now I have used Webnode for garner of papers and essays. Site123 is for classification by themes. Webnode's SRFL is adopted to invitational site for the time being.

CITATION FROM LUDWIG WITTGENSTEIN.
Citation from Ludwig Wittgenstein
TRACTATUS LOGICO-PHILOSOPHICUS Translated by C. K. Ogden
Dover edition
Text is lined up according to the order of citation at the essay, The Time
of Wittgenstein
6.521
The solution of the problem of life is seen in the vanishing of this problem.
(Is not this the reason why men to whom after long doubting the sense of
life became clear, could not then say wherein this sense consisted?)
6.432
How the world is, is completely indifferent for what is higher. God does
not reveal himself in the world.
6.35
Although the spots in our picture are geometrical figures, geometry can
evidently nothing about their actual form and position. But the network is
purely geometrical, and all its properties can be given a priori.
Laws, like the law of causation, etc., treat of the network and not of what
the network describes.
6.54
My propositions are elucidatory in this way: he who understands me
finally recognizes them as senseless, when he has climbed out through
them, on them, over them. (He must so to speak throw away the ladder,
after he has climbed up on it.)
He must surmount these propositions; then he sees the world rightly.
PUBLISHER'S NOTE by DOVER PUBLICATIONS. INC.

THE TIME OF WITTGENSTEIN
The Time of Wittgenstein
TANAKA Akio
There surely exists the time of Wittgenstein for me.
That time about in my age 30s, in the middle of 1970s.
One may aware of the kernel of the problem after almost all the hardships
were gone and the problem is going under pursuing in the daily work for
oneself, as Wittgenstein wrote at 6.521 in TRACTATUS LOGICO-
PHILOSOPHICUS.
Wittgenstein wrote on language immanently at least in TRACTATUS.
He also said in TRACTATUS 6.432 that how world exists does not care from
the higher dimensions.
I also wanted to write on language from the immanent side in language.
But I had not any pursuing method for writing on language at that time,
only remaining set theory typically presented by Bourbaki that some
translations were surely on my desk.
Set theory was enough fascinating at the time, but it did not give me any
relative and constructive situations on language or widely on the world. It
was isolated and non-relative for writing on language. I wanted the bond
of the world.
Now I have geometry for which the world can be bonded enough tightly.
In 1970s I was never aware of the existence of geometry by myself,
probably not being influenced from Wittgenstein's 6.35 in TRACTATUS,
Geometry absolutely tell nothing on how the figure is and where the figure
situated.
So I had remain silently in the days not being able to write on the theme,
the basic essence of language. Then I never knew the object on language,
language universals that was taught from CHINO Eiichi later in 1980s.
CHINO showed me the paper of Sergej Karcevskij, Du dualisme
asymétrique du singe linguistique. The theme determined my remain life
hereafter. CHINO was the true teacher of my study.
Wittgenstein wrote at the last 6.54 of TRACTATUS that his some
propositions must be abandoned. I began to go through the wood of hard
theme of language universals by mathematics especially using geometry.
About what can be told to, I never must be silent.

HENRY THE FOURTH FOR SAEKI SHIZUTO AND SHAKESPEARE
Henry the Fourth, For SAEKI Shizuto and Shakespeare
TANAKA Akio
In my mid-20s, I had worked at a high school in Tachikawa, Tokyo. One
day, after teaching class, I waited the colleague at the physics study room,
who was two year older than me and the best friend at the school. At the
room he was absent and I waited sitting the chair and began to read the
bringing book for the time if he was absent.
The book was the compact-sized complete works of Shakespeare. In those
days, I had time to time to time read Shakespeare for researching what
was poetry or verse's essence. I had strongly wanted what was verse or
how verse differs from prose . But never I had grasped the tail of it.
Several papers and books were already read at that time. Some poets' and
researchers' writings were also looked through. But I had perfectly never
made sense of it on verse. It was the very precious theme for me on the
way studying language. For example, what is the rhyme of verse or what
difference occurs between verse and prose? So I decided to read
Shakespeare which seemed the most typical verse work in the world.
When I was reading Shakespeare on the laboratory-work desk in my
friend study room, I suddenly understood perfectly the essence of verse
by the beginning of the play, King Henry the Fourth's saying. It became
one of the biggest pivotal points of my life.
The complete works was bought at old book store at Kanda, Tokyo. Its
jacket was dark red and very light in weight. Probably the book were so old
and enough dried up. I liked its classical binding.
On the colleague returning the room, my mind was swaying for a while
with my happy finding. The friend's name was SAEKI Shizuto who always
taught me the many wisdom related with life and study by his sensitive
talent to nature and universe. He was teaching geology in the high school.

THE TIME OF LANGUAGE ODE TO THE EARLY BOURBAKI TO GROTHENDIECK
The Time of Language
Ode to The Early Bourbaki To Grothendieck
TANAKA Akio
In early 1970s, I had think of language from the side of mathematics, that
level of mine is very low and primitive, moreover I never had any talent to
mathematics.
But my eager to trying the approach was going to overcome hard barriers
before me. So the route had really fascinated my mind for long time.
At that time I had read Chinese classics almost every day. WANG Guowei*,
DUAN Yucai and WANG Yingzhi. They were giants on Chinese language,
both historical and modern.
On the other hand I had thought of language generally, not defined by
Chinese.
But in front of the vast world of language, I had stood still lonely, not
taking any method for approaching.
Mathematics was the only gleam of hope in the wasteland.
I never took the route of ordinary linguistics.
I really dreamt a dream that time.
There exists set theory before me.
Probably there was the influence of Bourbaki**, that several translations
to Japanese, shared from Tokyo Tosho Publisher, were on the desk of
mine.
My talent and endeavour were so low, so I had not any results at that time.
My desire was deep but my hand was so shallow.
The time passed by.
In 1979 the meeting again with CHINO Eiichi*** made me the chance to
learn on language, the object was clear and direct.
Language universals by mathematics became the never-ending goal of
the study hereafter.
Sergej Karcevskij**** gave me the courage to the research.
All the way to investigation were taught from CHINO, who was the
genuine teacher on language.
In mathematics I took the route from geometry, especially by projection.
Now I stand at algebraic geometry.
Grothendieck is in the northernmost at the end of Bourbaki.
SAITO Takeshi said at the essay on Grothendieck***** that the object of
mathematics for Bourbaki was the set of being attached by construction
and the object of mathematics for Grothendieck was the object of category
representing the presentable functor.
The time has come for describing****** on language by mathematics
despite my poor ability.
Sincere thanks for the pioneers letting us make the fascinating route of
modern mathematics.

[Note, 28 October 2014]
When I first learnt French in 1964, I was the second grade of high school.
My aim to learning was to get the lowest readable situation for modern
poems of French Symbolism represented by Arthur Rimbaud and Paul
Verlaine.
Afterwards in 1969 I knew the importance of Martinet's work at the
linguistic class of university. Probably in the early 1970s, I bought
Bourbaki's books at the old-book-shop at Kanda, Tokyo, when
Bourbaki's fame reached to the poor-talented linguistic student like me.
I was enchanted Bourbaki's works and I somehow would like to adopt
their results to my linguistic study. But my mathematical level was too
low to get near Bourbaki's world.
From those days my wandering around mathematics and linguistics kept
long long way like the Beatles song, The long and winding road. What I
again met mathematics, especially algebraic algebra was already over the
twentieth century.
From 2003 I began to write papers being assisted with CHINO Eiichi's
advice and Sergej Karcevskij's work. At that times Chinese Qing dynasty's
vast linguistic works topically represented by WANG Guowei was also
assisting my study.
At the result my first satisfied paper, "On Time Property Inherent in
Characters"1 was completed. The theme in my life, model making of
language universals was begun further later in 2008 at Zoho site 2 and
sekinanlogos 3. At Complex Manifold Deformation Theory 4 I started
writing more clearer descriptive papers by mathematics especially
according to algebraic geometry. And now I step up one more and entered
in arithmetic geometry 5 for solving more difficult themes such as
dimension, synthesis and fusion of meaning in word.
Refer to the next.

[Note 2 2 May 2019]
5 years passed from I wrote Note at October 2014.
The situation for the research changed rather largely.
I and wife became older and I become 72 years old this summer while the
both have illness.
We often go to the hospital for the treatment for what I often think that all
the illness are probably on the nerves which make persistent flows in our
body, which inevitably need energy for fluidity.
At these circumstances I began to write a new paper titled What is signal?
The existence that generates language, Original title, What is signal? A
mathematical model of nerve.
The text is the next.
https://srfl-theory.webnode.com/news/what-is-signal-total-edition-
21-november-2018-23-april-2019/
So far I have thought of language at the point from language universals
which are the most fantastic theme for me. But illness and its base nerve
showed me the new site of language that is the real base of language. It
was the signal which has energy and flows and hatch language in the
human being.
Now I stand back at the manuscript written in 2003 at Hakuba, Nagano,
Japan titled Manuscript of Quantum Theory for Language. The text is the
next.
https://srfl-paper.webnode.com/news/manuscript-of-quantum-

may be unified being constructed for human being.
