A calm age never lasts

As the world changes, people who know no history fill the earth. That, too, is the way of things. To think about the future, we must look through the lens of history. One could even say that those who do not know history have no future. But history must not be mere documents. It must not be the interpretation of what has already been signified. History is the living trace that those who came before us left of their lives. Japan today seems peaceful, home to a hundred million people. Look back, though, and there were times when the streets were strewn with corpses.

Looking at the world system as it is now, which only appears to have advanced, and at the countless systems liquefying inside it, no one imagines that such a hell could spread across the streets of a developed country. But history teaches that a time that seems calm and safe never lasts long. And what matters most is this: the rot of the human heart always brings judgment from heaven. We already see nature beginning to strike back at humankind, and we live through it every day. This is only the prologue.

Osaka, where I was born and raised, is now one of Japan's great cities. Walking its streets, no one would believe that a great many corpses once lay here, or that an event that did much to shift the course of history took place on this ground. In fact, few people now even know that history. So the theme this time is a question: what is a "living human being"?

I ask because I have felt, personally, that meeting a "living human being" has become an extremely rare experience in our time. This is strange. The world's population is said to have passed eight billion, or to be higher still if you count those who go uncounted, and it is rising so fiercely that it is on course to pass ten billion. You would think that as the number grows, the number of living human beings would grow in proportion. The fact is the reverse: the more people there are, the fewer living ones. The problem of the present is that populations, like everything else, swell magnificently in number while quality does not improve at all. Or rather, by the manners of our time the right thing is to raise quality and quantity together, yet we still cannot escape the tendency to lean to one side, and we remain stalled.

A "living human being" is not someone whose heart merely beats and who merely goes on breathing. We moderns are desperate to extend our lives, but to prolong life with no life in it is folly of the highest degree. The more I see everyday life in Japan, a super-aged society, the harder I ask myself what a living human being is. That is because the figures I see are our future, or a future more wretched still, which grows more likely by the day.

To truly "live" is to hold, without remainder, the vitality a human being is born with, and to sharpen something that cannot be put into words, like magma seething in the pit of the belly. Such people stake life itself and give themselves wholly to daily training. Others often cannot see that training, because it is what we may call training of the heart. Mind and body are not separate. They are not two.

And one day, set off by some event, that sharpened, magma-like vitality erupts, with all its stored energy, in tremendous endurance and explosive force, and becomes the power that confronts life itself. To be present at such a moment is to stand at the epicenter of the "life" we have lost. To take back living itself must seem a strange theme to modern people. But it is plain that what we think of as living has already moved away from its true form. The question is how far we can press ourselves, asking whether we are really alive.

When I look over the scene today, I cannot help but shudder at how alien it is. By my own rule of thumb, anyone who knew daily life before the iPhone appeared, before the great nervous network of the internet covered the world, who knew the faces of people in those years and the look of the streets, will find the present extremely strange, like a shell drained of vitality and spirit. In Japan, I recall that the iPhone was released in early 2008. I was about to graduate from high school, and my classmates were entering university. Social media did not yet exist, or was not yet common. So our generation turned eighteen just before the problems we have today arrived.

From then on, the faces of the people around me changed fast, and I remember it still. Why, I still cannot say, but since the rise of the iPhone and social media it has seemed to me that human faces have changed. What was once called a human being became, before anyone noticed, something else: a machine, a device, a part of a system. Worse, it is no longer even a human being in the old sense. It exists only as a heap of domesticated animal life. I cannot help feeling a strong sense of wrongness and strangeness at this state of things.

From this devastated plain, no one who lines up fine phrases and pretty talk and cries out "how should human beings live?" will be heard. Their words will echo in the void. The definitions and concepts of the "human" that is made the object of such talk have themselves lost the weight of life they once carried, and drift. In an age that can say nothing unless a neatly arranged, bleached "something like a human being" is given a meaning and affirmed as the new human, the expression of our lives has nowhere to go. That is why, as a reaction, the present has opened room for a few people of strong conviction and resolve who aim to live. This situation is itself something we can recognize as a repetition, by knowing history.

The world today overflows with people who are nervously irritable, who scatter mere discontent and complaint, and they keep insisting that this is "human feeling." But the sudden, reactive emotion (reflex) that sweeps through the world is far from true vitality. In this state, to ask what a human being is, or what it means for a human being to be human, or how to live, would be almost pointless labor. We are standing on the plain of a ruin, "the world where human beings once lived."

Even so, it is also a fact that a strong vitality, uneasy at this sight and unable to bear it, and trying once more to ask what a human being is, is beginning to appear in places across borders. Since it is extremely hard to find a "living human being" among the people alive now, we must look for the source in the waters of history and learn from it. Then we will know that every age was much the same. To look into those depths this time, I want to take up the story of a man born and raised in the same place as I was. I do not want only to set out a historical record. I want to press close to the heart of this man, and so think about what it is for a living human being to exist.

He is Chusai Oshio.

He is generally called Heihachiro Oshio today, but up to the war he was known as Chusai Oshio. Chusai Oshio (1793–1837) was born in Osaka in the late Edo period, into a family of officials who served at the town magistrate's office. He lost his parents early, though, and had to take over the family trade while still young. He was compelled to enter service as a yoriki, a post in the bureaucratic police apparatus, as we would call it now, that judged criminals. But from childhood he was not the sort to belong to an organization and domesticate himself to a system. He was a man of fierce passions. He was short-tempered and quick to fight. His violence was so hard to handle that his grandmother, out of worry, took the little Chusai to a shrine every day and prayed to the gods that his temper would be cured.

Everyone knows, though, that a child of rough temperament can change completely when a fine teacher appears and shows him how to spend that energy in the right direction. For Chusai, the teacher was a book. One day a dealer in old things (itinerant peddlers like him wandered around Osaka and other towns then) came to his grandmother, who had raised him, to sell used books. Among them was the Old Text of the Great Learning (Guben Daxue), with a few other volumes. She was an avid reader and bought it at once.

This is confusing, so let me explain. The Great Learning was originally one chapter of the Book of Rites. The movement of Neo-Confucianism in the Song dynasty prized it, and it became one of the most important Confucian classics. Then a fierce dispute arose. Critics held that the Song version was only the arbitrary ornament and interpretation of later Confucians, and that the truth lay in the Great Learning as it was before Neo-Confucianism. The name split, and the custom grew of calling the original the Old Text of the Great Learning to tell the two apart. There is no need to think hard about it here. Please take it simply as a teaching from before Neo-Confucianism.

The boy Chusai happened to find this Old Text of the Great Learning that his grandmother had bought, and for some reason he begged her to teach it to him. At that time Japanese intellectuals added marks called kuto to the original text, written in classical Chinese, and through these they had by then taken command of the trial and error of reading Chinese in Japan. Any intellectual was expected to be able to read at least that much. His grandmother, who had always been keen on learning, could do it, and so she taught Chusai the kuto herself. Strangely, his violent temper began to settle. Before long he was absorbed in reading, and he was preparing the soil in which his natural gifts would flower.

Through this fated meeting he wished to give himself to learning. But at fourteen he had to take over his grandfather's duties and enter service at the government office. For Chusai, who had touched the teaching of the Confucian sages early, it was not easy to live as a cog in an organization the way officials did.

The learning I mean here is also not what we picture today: the dull procedure of graduating from university and graduate school, taking a doctorate, getting a job, and listing one's social standing in a profile. True learning is the place where one living being collides with another. It is the moment when life shows itself most, the root activity by which a human being is a human being. It is a burning of the soul, like the seeking of the Way in religion. But as everyone knows, such a chance rarely comes. There are countless universities in the world now, and countless people who lecture as individuals. Yet how much living learning is there? From experience, everyone knows they are lucky to find one for themselves. And a life changes greatly through that one fated meeting.

So Chusai spent his days reluctantly going to the office, and the first event that changed his life took place. Idly, he looked into his family genealogy, and learned that his ancestors had been of the Imagawa clan, and that even after entering the service of the Tokugawa they had been granted land in Izu for their merit. This happened around the beginning of the Edo period. I will not go into it this time. Simply put, though he himself had been born into the family of an official, the family had in origin been a distinguished one, and his ancestors had once rendered service to the Tokugawa, who opened the Edo shogunate.

Looking coolly at his own circumstances, he began to doubt. His ancestors had won distinction, done work worthy of the family crest, and been called into service by the Tokugawa shogun. So why was he, of that blood, working every day among selfish and crafty people in a place like this? He felt strongly that his way of life was a disgrace to his ancestors. But the age had hardened into fixed formal status, a peaceful time in which there was no fighting and no chance to win distinction. He cursed his fate, asking why he had been born into such an age and why his parents had died so soon. To work off the pent-up frustration he turned from study to the martial arts. He learned Nakajima-ryu gunnery and Saburi-ryu spearmanship, which is still the only one handed down in Japan to this day. His fierce temper, his large frame, and his strong, gifted body all worked in his favor, and he grew so strong that he had no rival around him. Had he been born in the Warring States, when warriors contended in every region, he would surely have won great renown. But the age had nothing to do with such things. The more someone of purpose knows history, the more often he wishes he had been born in another time. Chusai was the same.

And the age was the late Edo period, when fools like those of today swarmed everywhere, who misused knowledge and thought only of their own gain at the expense of ordinary people. In an age when vested interests were spread everywhere and rules and norms were enforced to the letter, there was nothing even Chusai could do. He could only work off his frustration every day in study and martial arts. As long as the system held and their own standing was safe, it was no concern of theirs if ordinary people suffered or what became of others. What more could they want, so long as their own gain was secure? So they allowed no new challenge of any kind that might threaten their gain and interests. Domesticating oneself to the system was simply the way to rise.

This period was, it is said, when Chusai was eighteen or nineteen, a sensitive age, and we can feel directly the great pain and frustration of a young man who could do nothing. But he did not give up on living and choose, as the other officials did, to become a corpse while still alive. His next turning point came at twenty.

It was then that he realized it. The wavering of his own heart might be the real problem. Until then he had blamed everything on the age and on others and had done nothing but lament his circumstances. But what could a single petty official do in society? Nothing at all. If so, the cause was that he had not fixed his gaze on his own heart in reflection, and had only sought the answer outside. That, he understood, was the very life that shamed his ancestors, and it was not truly living.

Here he threw himself into study again. According to one account, he went to Edo (Tokyo) at this time and entered an institution of Zhu Xi learning run by the Hayashi family, scholars in the service of the shogunate. In any case, it is a fact that he now set foot in Confucianism in earnest.

Confucianism is still, worldwide, far too often mistaken for a crabbed, theoretical teaching, bound in regulation and hostile to personal freedom. The original is nothing like that. The teaching, however, leaves room for interpretations convenient to the philosophy of each age's rulers. Clever intellectuals who called themselves Confucians exploited this, bending the teaching of Confucius and Mencius further and further, and the Neo-Confucianism of the Song then changed it greatly, which is why people today resist Confucianism so deeply. Japan is in fact still built, at the root of its official philosophy, on this mistaken reading of Confucianism, and since the late 1990s in particular this Zhu Xi system has made a comeback. A rigid totalitarianism, a precedent-ism that allows nothing new, individuals forced to sacrifice themselves to organizations and systems: it embodies all the bad sides of Confucianism, so it is true to a degree that Confucianism has problems. But the original is not like that. The Confucian sages were those who faced most squarely the question of what it means for a human being to live as a human being.

What I take to be the mark of Confucianism is that it holds a principle that does not domesticate the self to a system. It teaches that you do not change what is outside you, others and systems, but first change yourself. You start a transformation, a revolution, in your own heart first, and train yourself thoroughly. Then whatever the age, whatever the system, whatever others do, what you do and what you must do is the same in every era. And changing the "inside," the self, is overwhelmingly harder than changing the "outside" of family, society and state. When I watch people today pressing on with social reform and national reform, I find them comical, because they do not look as if they have gone through self-transformation, the harshest and hardest thing for a human being. There is no change of the outside without change of the self. More than that, when you yourself are changed by self-transformation, the way you see the outer world is changed entirely.

Absorbed in Confucianism, and already gifted in practice, Chusai learned the truths of the sages' teaching one after another. Confucianism teaches individual training, but it places equal weight on fulfilling the duties given to oneself. So Chusai, who until then had done nothing but lament what use office work was to his future, and why he must spend most of his life with men who talked only of the rice market (the stock market of the day) and judged the criminals brought before them, changed his attitude. He took the duties that fate had given him now as the practice of self-transformation itself, and began to take them on. He resolved that this was the only way to open his life. That a young man in his early twenties could realize so much shows how precious true learning is.

Yet this man, who had awakened through self-transformation, lived in a world that, as we all know, is not a system built to lead such awakened, living people to happiness. If anything, historically the travelers of a rightly lived life have a strange fate that draws them into a deep abyss of grief. Chusai was no exception. The fate that awaited him, awakened so young, was an unbroken run of cruel trials.

To master learning deeply, Chusai went from one private school to another that taught Confucianism, and began to study in earnest. But it was an age of extreme corruption, and the worst of it was dry, dead education wearing the skin of learning. As today, the learning of the time was full of senseless teaching in which masters taught disciples only what had already been signified. They taught the surface skills of reading the classics of Confucius and Mencius aloud and of commentary, or they set a topic, sent students to the sources, and checked the answers of the best pupils, a folly everywhere. There was no living learning there, and no confrontation of living beings between master and disciple. It had no power to move the heart, and was only an institution that bred reserve officials with clever bureaucratic minds. In short, it was meaningless mechanical education.

Here Chusai was disappointed once more. What he sought was not to spend his life on devising clever tricks for surviving among outward forms. He sought in learning something that pressed on a life in the urgency of its inner need. Two hundred years had passed since the shogunate was founded. The fervor of the early shogunate, a heat close to frenzy for a new age, was gone. It was an age of fixed status built on a fixed system, in which titles were everything, just as they are now. There was no need for living human beings in such a world. To those who wanted to keep the system running they were only a nuisance. On the surface it was a peaceful society, but inside it was as empty and lifeless as ours. At last Chusai despaired, and his days passed without joy in anything he did. He was twenty-four.

But fate has a strange power. When someone has resolved to live in earnest, it grants him the chance that fits his hardship. Chusai, grieving that even in the great cities of Osaka, Kyoto and Edo there was no education that answered his inner need, was saved by another turning point, and it too came as a single book left by one who came before. This encounter became the point at which he began a life he could not escape.
