Rough Transcript:

Welcome to Sengoku Daimyo's Chronicles of Japan. My name is Joshua and this is episode 139: Observing the "Natural" World.

Members of the Onmyou-ryou, dressed in the official robes of their office, sat around in their observation tower, measuring the location of the stars. They kept their light to a minimum, just enough so that they could write down their observations, but not so much that it would destroy their vision. As they looked up, suddenly they saw a strange movement: a streak through the sky. They waited, and observed, and then there was another, and another after that. It was as if the stars themselves were falling from the heavens. They watched as it seemed that the constellations themselves were melting and falling apart. Quickly they scribbled down notes. Tomorrow, with the light of day, they would consult various sources to see just what it could mean. For now, their role was simply to observe and record.

Welcome back, everyone. It is the height of holiday season in the US as I record this, and in our narrative we are in the middle of the reign of Ohoama, aka Temmu Tennou, who came to power in 672 and who has been shoring up the Ritsuryo state instigated by his late brother, Naka no Oe, aka Tenji Tennou. We have talked in recent episodes about how Ohoama put a lot of the state under the control of members of the royal family, or at least those with claims to royal blood, and how he had also begun work on the Chronicles—the very works that we have been using to try and understand the history of this and earlier periods.

It seems clear that Ohoama and his cohorts were doing their best to solidify their control and, in the process, create what they felt was a modern state, leveraging the continental model, but not without their own local flavor. After all, they were also investing in the kami based rituals of state and specifically in Ise shrine, which they claimed as an ancestral shrine for their lineage.

This episode, let's dig into another thing that was getting reported around this time. And that is… science! Or at least observations of the world and indications of how people were interacting with it.

Before going into the subject, I want to acknowledge that "science", or "Kagaku" in modern Japanese, may not look like what we think of as "science" today. The word "Kagaku" itself appears to come about in the late Edo period, and became associated with the western idea of "Science" in the Meiji period. Today we think of it as observations, yes, but also testing via the scientific method.

I think it might be more appropriate to categorize a lot of earlier science under a term like "learning" or "study", and it seems to have encompassed a wide range of topics of study, some of which we would include as "science" and some which we might refer to more as "arts". There is also a very fine line with religion and philosophy as well.

From a modern perspective, I think one could fairly argue that "science"—particularly the so-called "hard" sciences—refers to something that can be empirically tested via the scientific method. So you can see something, form a hypothesis, create a test, and then that test should produce the same results no matter who conducts it, assuming you account for the variables.

And please don't @ me about this… I know I am simplifying things. This isn't a podcast about science unless we are talking about the social sciences of history and archaeology.

In contrast to our modern concept of science, much of what we see in the Asuka era is built around using our reasoning to arrive at the truth of something. In cases where we are dealing with clearly physical phenomena that have observable causes and effects, this can lead to remarkably reliable results. One example of this is calendrical science—it isn't that hard to observe the passing of days and seasons. Even the rotation of the earth and the movements of stars and even something with as large a period as comets could be observed and tracked, especially if you had centuries of data to comb through. In fact, they often would predict things that it turns out they couldn't, themselves, see. They could predict that an eclipse would occur, for example, even when that eclipse was only visible somewhere else. And they didn't have to calculate gravitational pull, mass, or distances between different heavenly bodies for that to occur.

Similarly, in the agricultural sphere: you had so many people who observed the seasons and would figure out new ways of doing things. It doesn't take an understanding of chlorophyl to know that plants generally do better when exposed to sunlight.

I believe the leap happens when you get to things that go beyond purely observable means. Sickness, for example—how do you explain viruses or germs without equipment like microscopes to see what our eyes alone cannot? And if such "invisible" things could cause so much damage, then why could there not be other "invisible" elements, such as kami and boddhisatvas?

And as humans we are driven to make connections. It is one of the things that has driven our technological innovation and rise, but it is also something that can easily go awry. Like when you are sitting in a dark house, alone, and you hear a noise. Rationally, you might know that houses settle and creak, but that doesn't necessarily stop your brain from connecting it with thoughts that someone must be in the house making that noise. Or even how we make judgments based on nothing more than how someone talks or what they look like, because our brains have made connections with those things, for good or ill.

A large part of the rationalization that was accomplished in Asian thought had to do with concepts of Yin and Yang, the negative and the positive, the dark and the light. This was thought of as a kind of energy—qi or ki—that was embedded in things. We discussed this somewhat back in episode 127, because yin yang theory, along with the five element theory, known as Wuxing or Gogyou in Japanese, became embedded in the idea of the calendar. Why was summer hot, except that it was connected with an excess of fire energy? And the cold, dark days of winter would be associated with an excess of water, naturally.

I should note that while this is one of the more comprehensive philosophical systems in use, it was not the only means by which various phenomena and effects were rationalized. After all, it had to be imposed on a framework of how the world otherwise worked, and descriptions of the world came from a variety of places. There was, for example, the Classic of Mountains and Seas, or Sanhaijing, which detailed the world as envisioned in the period before the Qin dynasty, although there were occasional updates. The Sanhaijing described regular plants and animals in the same breath as gods and monsters. There were also various buddhist sutras, which brought their own cosmological view of the universe that had to be squared with other visions, including those passed down locally describing the archipelago as the "Reed Plain" and giving particular importance to eight of the islands—though which eight depends on which variant of the creation myth you are referencing.

To categorize the study of the natural—and what we would consider the supernatural—world around them, the Ritsuryou set up specific bureaus. One of these was the Onmyou-ryou, the Bureau of Yin-yang, also known as the Onyo no Tsukasa. This Bureau oversaw divination, astronomy, time, and calendars. At its head was the Onmyou-no-kami. Below them were the various scholars studying the core subjects, as well as technical practitioners to carry out the rites and divination.

On the continent, priority was generally given to astronomical and calendrical studies, and many of the more magical practices or rituals would fade away, likely because there were local Taoist institutions who could take up much of that work. In Japan, however, it seems that the calendrical studies tended to ossify, instead, while onmyoji came to fill a role not just for the state but also among the population for divination and other such practices. Even into the Edo period one could find private onmyoji, and the Bureau itself lasted until the very beginning of the Meiji period.

Another important institution of the Ritsuryo government for learning was the Daigakuryou, the Bureau of Great Learning. Students of Japanese may recognize the term "Daigaku" referring, today, to universities.

The original concept for the Daigaku-ryou, or Daigaku no Tsukasa, was focused on the study of those things that were considered perhaps a bit more practical and necessary to anyone who might want a political career. Since this was founded on concepts of Confucian government, it is little wonder that it was originally designed to focus on Confucian studies, among other things. This fits into the idea of a supposed meritocracy, where one's education was part of the examination. You may recall from Episode 115 we talked about the National University in Chang'an, which is likely something that the Daigaku Ryou could only ever dream of becoming.
