This figure also shows the influence of Aristotle's theory of the four causes. Baien believed that the universe was built on four fields made from four basic materials and their combinations.
Among the four materials, "氣" between the first and second quadrants is defined by Baien as "something intangible". "物" The between quadrants third and fourth is the "Materials". "性" between the the first and fourth quadrants means "Character" and "體" between the second and third quadrants means "shape".
Based on these, it can be deduced that the "天界" in the first quadrant is the field that is shapeless but has character. Baien himself wrote in the diagram below that this is time and space. The upper half of the second quadrant in the figure below corresponds to that. Click to learn more. The literal translation of "天界" is Heavenfield. However, it has no religious significance. That's where we are now, and far into the universe, in the field of time and space.
Baien does not show the physical fields in the figure above. He always had thought about the Global biosphere where all beings exist. He did not want to think about the physical and mathematical mechanism of the world. The thought of him was in the Lifeworld every time, and never believed common knowledge about nature in the era. Baien searched a logical system which could total explain the globe and universe.
The same reasoning applies below. "機界" means the region of the orbit. There are the movements of rise and fall of Earth's gravity, the rotation of celestial bodies, the diurnal and annual motions of the celestial sphere, the orbit of comets, the realm of shooting stars, the orbit of airplanes, the flight lines of birds in the sky, the flow of clouds, and the flight lines of young people who put on the wingsuits more recently. Of course, the trajectory of a ball thrown by a pitcher and the path of a home run hit by a batter fall into this category.
They have trajectories represented by mathematical lines but are nonmaterial. They have their shapes, such as straight lines, circles, and parabolas. So you can see that they made from both "氣" which means non-material, and "體" which means shape.
In the third quadrant, "體" means something with shape and material. It includes everything from the celestial sphere to small insects on the earth to cells and invisible objects in the world. Click to see a typical example. When you click on a character in the linked diagram, you'll see something with each shape in nature.
In the final fourth quadrant, "色界" refers to regions of light and darkness. It is, of course, also a region of heat and cold. Click the word for more detail.
All that tells us is that these four fields only correspond to the left half of the "神物剖析図" above. In the right half of the quadrants, all of them given names that summarize their typology and intrinsic activity, the inevitable phenomena such as day and night turnover, and the accidental phenomena such as earthquakes and floods. However, they do not appear in space and time without materials. Baien has written like that in GENGO.
