Mystery and mystery, the door of all wonders and metaphysics
As early as more than 2,000 years ago, the ancient Chinese sages discovered that "heaven" (mainly referring to the solar system) dominates everything in us, and put forward such a great and unprecedented law or axiom as "the gate of mysteries and mysteries, and the gate of all wonders". This is the first principle and meta-starting point of the world's only social science in the world, and it is also the cornerstone and essence of the social science rational system formed by the world's earliest deductive method. The ancients observed the changes of the sun's movement with instruments such as sundials and rulers, and the black shadow projected by the sun on the sundial and ruler was called "Xuan".
The true meaning of "the length of the sun, the day and night and the changing shadows of the four seasons are the origin or starting point of revealing the laws of nature". This is the first principle and meta-starting point of true Chinese Taoism, and it is also the first principle and meta-starting point of the world's only social science system.
Mysterious and mysterious--- long and short sun, day and night, and the changing dark shadows of the four seasons.
The crowd is nature or all things.
Wonderful --- law
The gate --- origin, first principles, or meta-beginnings.
Metaphysics" Many people interpret it as the doctrine of "mysteriousness", which is wrong, metaphysics comes from the "Tao Te Ching" "mystical and mysterious, the door of all wonders". The ancients revealed the law of the change of the sun's motion through the black shadows on the sundial or ruler, day and night and the changing seasons, and the so-called "Xuan", so the real meaning of metaphysics is the doctrine of the law of the change of the sun's motion. The sundial is a tool to measure the length of the sun's shadow and the movement of the sun's shadow, and the black shadow of the sun on the sundial is called "Xuan".
