Giant trees

When I went to Cambridge, U.K. for the first time some 15 years ago, I was fascinated by the trees. Walking along the path in Jesus Green, my heart was won by the huge old trees flanking the straightway. The fact that people in Cambridge took care so that these lovely things could be preserved, was enough testimony of the generally benevolent spiritual environment of the city, not to mention the excellent colleges and the University.

Wherever I go, I look for giant trees, and try to make friends with them. I touch the bark, look up at the leaves, and feel the lights and winds that have nurtured the remarkable specimen for all those years.

The giant camphor tree in Kamo, Kagoshima is one of my favorites. I have visited the tree several times, and get a renewed inspiration every time.

Over the years, the giant camphor tree has been revered as a deity. The tree is estimated to be about 1500 years old.
It is interesting how the passage of time left traces on the surface of the bark, and twisted the whole body in an impressive, dynamic form.

Time brings venerability, and venerability is made visible by the interaction of so many elements, directed by nobody, meant for no admirer.

Thus, I am just an incidental admirer.

Giant trees are one of the most ancient and powerful art forms found in Nature. The incident makes one cry.

Can we really speak of "red"?

Ludwig Wittgenstein wrote, at the end of Tractatus Logico-Philosophicus, that "Whereof one cannot speak, thereof one must be silent."

I was discussing things with Ken Shiotani, my philosopher friend, during the annual "Ojisan Onsen" ("Middle-agers hot spring") trip.

Shiotani referred to the philosophy of Spinoza, Frege, and Leibniz. Shiotani stressed how in some systems of thought God appeared as an absolute infinite, something beyond human comprehension. Of God, no description is in principle possible.

Then I said to Shiotani that God-like things should be everywhere. Can we really speak of "red"? How about "love"? "Time"? The conversations we carry are full of intractable and distant things, the distance closed only incompletely by our incessant efforts to make the world tangible. But in the end, the essence of things remain inaccessible. Shiotani responded with his observations on the difference between the systems of Spinoza and Leibiz.

I and Ken Shiotani have been friends since we were the sweet age of 18. Talking about essential things in the small hours made us feel like students again.

Sumo wrestling with Akira

Akira Wani, now teaching at the law department of University of Tokyo, is a good friend of mine since senior high school. He is a legendary genius. Akira's score for the test conducted by the National Center for University Entrance Examination was top of the nation, taking 981 out of 1000. For the graduation essay book of the senior high, Akira wrote an essay titled "On the concept of glory in the Latin civilization", while the other students wrote on the memories of school life and other mediocre themes.

In the senior high school, we discussed many things, history, philosophy, esthetics, politics, etc. Meeting with Akira was one of the most fortunate encounters in my life. It uplifted my spiritual and intellectual conditions tremendously. When I entered University of Tokyo, I felt that the intellectual atmosphere rather deteriorated, compared to the intense interaction I used to have with Akira, although the university is supposed to attract the academically high achieving kids of the nation.

So the senior high school days with Akira was a heaven. I remember quite well one particular day, when I happened to see Akira Wani at the train station. He was reading a book. It was a biography of Queen Elisabeth I of England. Out of curiosity, I asked Akira "Why are you reading such a book?" Akira answered, "as I am busy with studies, I need to read such a book from time to time, otherwise I cannot maintain the balance of my spirit".

This morning I am writing about Akira as I suddenly remembered one episode from the senior high days.

In the sports class, we were one day told by the teacher to do sumo wrestling. Chance had it that I was to do a match with Akira. The idea of sumo wrestling with my respected friend was something beyond my imagination. Out of the blue, I started to laugh, and I could not really control myself. It was ridiculous, absurd, and yet so fascinating.

Finally, sumo wrestling we did. I don't quite recall who won. I remember though that Akira was quite solemn in the match, and conducted his duty as a serious wrestler all the same.

The variable unconscious

In the Brain Club (our research group's journal club) yesterday, Tetsuro Ishikwa, (Ph. D student) introduced Shurger et al. (2009). Their research reported that reproducibility distinguishes conscious from nonconscious neural representations.

I found the idea quite interesting. When we see an object, the conscious percept remains basically the same, no matter how often we may observe it. The unconscious cognitive processes associated, however, might be quite variable, corresponding to the heterogeneous multiple processes that makes our cognition robust.

Take the particular example of an apple. The visual image of an apple is basically the same, if we look at a particular apple from a certain angle and under specific lighting conditions. The significance attributed to the apple, however, might be different from time to time, depending on one's mood, memory, feelings, and the context in which the fruit is presented.

The picture emerges that conscious perception corresponds to the invariable in perception, while there is much variability in the related unconscious processes. It is the co-existence and co-dynamics of two processes of distinguished nature that makes human cognition robust and evolvable.

Portable texts

I think it was youtube which changed my attitude towards the portable modalities.

Used to be that I listened to the music on the portable audio player a lot, whether it was walkman or iPod. Nowadays, I don't listen to portable music that much.

The fun of listening to music on the youtube in the hotel room when traveling has changed my sensitivities to the portables. When you are walking on the street, or on the train, you are exposed to a lot of noise naturally. Listening to a portal music is done on top of that, which is sometimes OK, but not really perfect.

Listening to music in a hotel room, based on your whimsical moods, has opened a pathway for joy hitherto unknown, and in a sense made the portable music outdated.

Now I am more interested in portable reading. Whether it is the Amazon Kindle or Sony Reader, I think portable text has a great future.

In my life, portable music would keep having a place, but I foresee more importance assigned to portable text, while the music would return to the room and concerts. In that mood, I would be needing less of the earphone.

Wuthering Heights

The Wuthering Heights was one of the novels that I read in my teens in English language as I built up my linguistic ability and sensitivities for life in general.

The thing that struck me the most was the revelation of how Heathcliff, after Catherine's death, has been wandering around the Wuthering Heights in search of the loved one's spiritual afterglows. The image of the man walking in the wilderness, seeing the invisible, remained with me vividly, although the details of the novel has now escaped.

It is interesting how a certain type of human nature fascinates one. The respect for someone pursuing something that is beyond the scopes of the everyday has been the persistent trait of my adult life.

That kind of attitude has been nurtured by encountering a novel like the Wuthering Heights, and sharing the feelings and understandings with friends of the same feather.

Precious things are hard to find and keep.

Reading fever

It seems that something in me has sparked recently. I simply cannot stop reading.

I get on the subway just because I can read in the car. I read Spinoza, Wittgenstein, Schopenhauer, Wagner, Dazai, Natsume, Terada, Penrose, etc. and can never get enough of it.

I remember my past reading spells quite well. When I was 9, scientific fiction novels suddenly captured my imagination. I read all the juvenile novels available in the library. In the senior high school, I learned to read English novels starting from Lucy Maud Montgomery to Jane Austin and Emily Bronte.

I don't know what brought the current reading spree. I could keep reading all day, if it were not for the writings and meetings and lectures and television shootings that necessitate me.

I think there is something in my brain that has now gone over the threshold, and that "something" is telling me to keep reading, infusing me with a never satiable urge.

The reading fever is quite interesting in that it perhaps symbolizes a period of inner transformation, when one is carried by the tides of the unconscious dynamics to hitherto unknown territories of intellects and feelings.

This passion is interesting. I highly recommend people to be infected from time to time.

200 days

The entry "My mother and Hibari" marked 200 consecutive days of continuous entries, the writing streak starting on the 6th of June 2009.

I look back on my own perseverance with a feeling of humble satisfaction and resolve to keep the streak as long as the circumstances allow.

My mother and Hibari.

Hibari Misora is a legendary Japanese singer, sadly no longer with us. Hibari had a concert in the Tokyo Dome once, shortly before she passed away.

The thing is that my mother is a great fan of Hibari, and was lucky enough to go to the Tokyo Dome concert.

Yesterday, passing a Tokyo street, I happened to hear Hibari's voice, singing "Kawa no Nagare No Youni" ("Like the flow of a river"), and immediately remembered how my mother was enthusiastic about Hibari Misora and was overjoyed to be able to attend the concert. At that time, of course, mother did not know Hibari was to pass away so soon.

When I remembered the Hibari concert episode, I felt tremendously happy for my mother, who is up and well at the mature age of 75.

Well, that's all.

Imagine no universities

I know a university is a good thing. You meet your mentor, friends, and colleagues. It nurtures human knowledge, and updates and creates concepts for future generations.

On the other hand, a university is an institution. It harbors its members, while rejecting others. I know people whose lives have been crushed because they could not enter the universities they wished. There are the pompous and self-important types who just pride themselves on being or having been a member of a particular university. Since any institution has its elements of malice, and since we are living in the internet era, let's do what we can to promote the goodies and discourage the vices.

Imagine no universities. On the internet, you can access to endless sources of academic information. Do we really still need institutions whose members are limited, due to physical constraints, which have no significance in the internet era? Why don't we tell the kids that they can explore the universe of knowledge without necessarily belonging to a particular institution? Why don't we encourage the crushed people that they don't have to feel inferior because of some stupid entrance exams taken at the age of 18?

Why don't we say loud that knowledge is open, for everyone, for someone from the street, as well as for those in the "ivory tower"?

Imagine no universities.

You just need to know how.

The tools are here and now.

Eight Below

Here it is getting colder and colder. In a metropolis like Tokyo, the time you spend inside is considerable. As a consequence, I don't wear a coat, even in the middle of winter. I don't like the feeling of being "suffocated" by heat as one enters a building, subway, or a taxi with one's coat on. I would rather bear the biting wind as I walk for a few minutes on the Tokyo street, in order to spend the indoors in comfort.

Things were quite different when I traveled to Germany in January. It was very cold. Actually, I later learned that Europe was experiencing an unusual freeze spell at that time, with the temperature reaching 20 below zero Celcius.

Here's a picture I took in Weimar, as we were walking on the street one late morning in that beautiful city. The sky was clear,
and the sun was out. Even so, the thermometer read eight below.

On the night of arrival in Weimar, I think it was 15 below or something. When it is cold as that, I discovered that your nostril
hairs would freeze.

"Paki paki". That is the Japanese expression for something that gets frozen and stiff. I remember quite well how my nostril hairs went "paki paki" as I walked through the Weimar night. Actually, that was not an unpleasant sensation.

Even a cold-stupid person as I had to wear a coat then. One could not simply survive otherwise. It seems that I have a high (or rather, a low) threshold for coat wearing, and in Weimar that threshold was reached.

Gino Yu came to visit

Gino Yu came to visit Tokyo. Currently Gino is a professor at Hong Kong Polytechnic University. He was kind enough to accept our invitation, at a very short notice, to give a lecture at a class room at Meiji University, which was arranged by Prof. Masato Goda.

I came to know Gino when I visited Hong Kong for a conference. His personality fascinated me immediately.
He talks with such gaiety that sunshine seems to emanate from him. Gino is a "natural" in grasping what are salient and finding deep connections between things. Listening to his ideas is a delight for the soul.

I was glad that my students were exposed to his good influence. When you give a talk, the manner is as important as the content. A dull speaker bores the audience not necessarily because of poor ingredients but often due to a bad attitude.

Had a fun time afterwards in a Izakaya near the university.

Many thanks for your time and inspirations, Gino.

Tree house

When I made my pilgrimage to Bayreuth this last summer, there were several things besides Wagner that I captured my imagination.

I remember one house on the street vividly, on my way to the Festival house from the hotel. There was a tree house in the garden.

And it was just a private house. Imagine a tree house in your backyard! What fantastic child years you would have!
I have always been fascinated by the trees. Staying high up among the boughs for a prolonged time has been one of my unfulfilled dreams.

We noisy brats used to climb the trees, to the horror of the onlooking adults, and do various things. Somehow the tree time liberated our spirit.

From evolutionary point of view, it might be that one is more at ease and relaxed when one is on the tree, avoiding the hazard that comes from being on the ground, which makes one vulnerable to the attacks by predators. Climbing the tree, needless to say, gives one a magnificent view.

Books are made of trees, and the spiritual effects are accidentally similar to those by the trees. Reading books gives you the vantage point of a wider vista, where you can breathe more freely and without restraint.

Reading books on a tree bough becomes thus a fascinating combination. Something I haven't done to my satisfaction yet in my life.

Pub time in London

As the year comes near to the end, I remember things that have passed me. One of the highlights of my sojourn this round of the earth's sun-wise orbit was the visit to London with Shinya Shirasu in summer.

Although it was a short visit (only a crazy two nights stay), some things stand vividly in my memory. The Pub time for example. My favorite memory is facing Shinya in the London Pub, especially the one in Kensington, where we sipped the typically lukewarm liquid of English pride in that golden afternoon. I would have liked to spend more time like that. In actuality, our heavenly pastime lasted only for one hour, at the most.

I always say that one can "grow" the past if you return to it repeatedly in your memory. The pub time in London with Shinya is one of the precious mnemonic seeds that I would like to nurture as I close my eyes and escape into the kingdom of recollections and imaginations.

The lights corridor

The Meiji Shrine is one of my favorite places. I would like to stroll this haven in the heart of Tokyo.

The lights are never the same, as they come through the leaves of the trees, which have grown into mature shapes 100 years after they were transplanted from many places across the island. Before the transplantation, the shrine site used to be a grassland, I hear.

I would like to ponder and weigh, as I pass through the lights corridor. I come face to face with my unconscious, where I find many strange animals and vegetations.

And my whole body including the brain is the only recording devise. Photography has a limited power in capturing the moment. As I stroll, I vividly sense the environment and myself. I hark, remember, and project.

Before long I find myself in the busy Tokyo streets again. The magic is over.

The headmaster's platform.

I visited a couple primary schools on Uku island, an small island off Kyushu with a population of 3200.

In the school play ground, I found a very familiar platform.

Used to be that when there was a school gathering, usually in the morning, the headmaster would stand on the platform, and deliver a list of "dos and don'ts" to the pupils.

Other teachers and sometimes pupils would stand on the platform. When I occasionally stood on the platform, to make announcements as a representative of the pupil's body or to receive an award from the headmaster, I became very nervous. My legs would literally tremble.

Such a bittersweet nostalgia surges within one's bosom as one looks at such a object of sentimental values. The headmaster's platform.

All because a child has a magical power of imagination.



The headmaster's platform

In a nutshell, yes.

I am in Hakata right now, writing this entry. In the afternoon I am going off to Uku island, where an internet connection is not likely available. I am writing this entry in advance, and register it on the blogger system to be published on Monday morning JST, in order not to break the writing streak of the qualia journal, which would achieve 200 consecutive days in a row on 15th December 2009.

I am with Prof. Meguro of Kyushu University. We are discussing lunch. When I was asked what I would like, I answered "well, I would love to have something that comes in white, opaque soup, with a long thing made of flour, and a red fish roe which is rather spicy as topping, and you could have a second helping of the long flour thing if you wanted."

Mr. Atsushi Sasaki of Dentsu laughed, and simply said "you want a ramen noodle!"

In a nutshell, yes.

Prof. Meguro is giving directions as to where to find a ramen noodle restaurant. I am not sure if my wishes would come true.

I could not have been otherwise.

A few days ago I wrote about the Kaki (persimmon fruit). The sight of a tree standing against the blue sky, with its boughs full of kaki fruits, is one of the most striking and vivid in the seasons of autumn and early winter. As an inhabitant of the Kanto plane, I am so accustomed to it. When out in the suburbs, I am unconsciously seeking for the signs of season, the Kaki trees and Susuki (Japanese pampas grass), for example.

That sensitivities and feelings are products of the environment is not a striking observation. It is very much true nevertheless. We humans are products of the soil, just as the trees, which cannot move about by themselves, are products of the grounds on which they grow.

Spinoza, in his magnum opus "Ethica", argues that this universe could have been otherwise, due to the perfect nature of God. If so, we are products of this particular universe by necessity, and we could not have been otherwise.

To think that I could not have been otherwise brings a strange consolation.

The Orange Revolution.

When I was going to the Kindergarten there was only one drink that a kid loved. Fanta. In the children's gatherings, the adults would bring bottles of Fanta, as special treats.

First everybody seemed to love the grape flavor. When the pleasure time came, our small hands would invariably reach for the Fanta Grape bottles. There was actually a competition, in order to secure our own grape bottles, and not to be forced to accept the less desirable orange. It appeared as if the Reign of Grape would flourish for ever.

Then something extraordinary happened. One day somebody realized that the orange was not such a bad flavor. Maybe it was even better than the grape. A silent revolution was developing in front of our little eyes. Like a dramatic turn of events in a Reversi game, more and more kids would start preferring the orange flavor, until one day the little hands would reach only for the orange bottles. The grape bottles stood unattended. It was a sad sight.

To this day, I remember quite vividly how my world-view shook as the trend changed. Although it was a surely small shift in taste, I felt as if the ground on which my feet stood collapsed.

By the time I entered the elementary school, the Orange Revolution was complete. For some years, some of us small mortals did not forget how our sensitivities had been touched.

Eating Kaki

In Japanese, some words have double meanings. "kaki", for example, can indicate a persimmon fruit. It can also mean the "oyster". A strange property of natural language comprehension is that based on the context, one tacitly assumes that "kaki" is one or the other. When "kaki" is used in the context of the persimmon fruit, one almost never thinks of the other possible meaning.

There is a famous haiku poem which can be translated as "Eating kaki, The bells of the Horyuji temple, Ringing"

Kaki here obviously refers to the persimmon fruit, which is a fruit of the autumn. It is fitting. One remembers how beautiful Horyuji temple, one of the oldest surviving wooden buildings, appears when the leaves turn red in preparation for winter.

Yesterday, when walking in the street, it suddenly occurred to me, for the first time ever in my life, that based on the sound alone, "kaki" in the famous haiku poem can also mean "oyster".

"Eating Oyster, The bells of the Horyuji temple, Ringing".

The scene is changed dramatically. What a mismatch! A comical feeling is invoked, and the haiku poem is changed beyond recognition.

The strange thing is that it never occurred to me to interpret the poem in this way--until yesterday, that is. I wonder what struck my brain out of the blue. A strange combination of neural activities, perhaps.
