Tao philosophy describes the order of nature and defines the principle of that order. Tao refers to the natural, spontaneous harmony of the universe, so Tao philosophy is a Philosophy of Nature. Nature is in the phenomenal world. This principle may be shown in the proper order of the myriad things. It is difficult to discuss directly this order of nature, since the sole characteristic of this order is Oneness. However, we can see this principle in the proper interrelations of the myriad things in the nature. In other words, our proper views on nature can reflect the proper order of nature.
The principle of Tao may be summarized as the Principle of Oneness. When we understand this principle, some of our traditional views on Tao can be re-affirmed, but many other speculations are clearly unwarranted. Our immediate validation of this principle will be a logical interpretation of the Tao Te Ching. However, this principle is universal and we can see the same principle in many other philosophies. We may conclude that Tao philosophy is not a Chinese-only philosophy. It is a principle shared by many Eastern and Western philosophies.
Since this principle is fundamental in our reasoning, our analytic approach may be used in many other philosophical discussions. For example, the model shows how the objects can participate in the forms in the Theory of Forms of Plato. The similarity of Tao philosophy to other ancient philosophies, Parmenides and Plotinus in particular, is also astonishing. The principle of Tao is also consistent with many modern Western philosophical observations, such as by Schelling, Kant, Bradley, and Whitehead, etc.
Our model also shows the similarity between the logic of Tao philosophy and quantum theory; both are based on complementarity of the opposites in their descriptions of nature.
