1. Introduction
A Basic Theory of Tao Philosophy

In this paper, we present a basic theory of Tao philosophy based on the Tao Te Ching. This analysis is a continuation of a field theoretic approach to the basic concepts of Tao [WA04, WA05]. It is an attempt to show the similarities and differences in various philosophies at a fundamental level. The approach is also consistent with scientific principles.

We present the fundamental principles of Tao in Section 2 , where we show the architecture of Tao philosophy in terms of Wu 無 and Yu<有。 In Section 2.2 , we introduce the concepts of classical and actual states to show their relationship in the Oneness of Tao. These states belong to two levels of our knowledge. The classical states have to be superimposed in a transcendental way to reflect the intrinsic realities of Tao. This formalism reveals the Principle of Oneness 太一定律 as the fundamental nature of Tao philosophy: Every reality must preserve Oneness. In Sections 3 , we show the application of the Principle of Oneness in different domains and how we can achieve Oneness in each domain. Section 4 describes the Way of Wu<無為論and the Way of Yu 有為論as the Process of Actualization 實現程序 to achieve Oneness.

A Summary is given in Section 5 . We discuss the dynamic nature of Tao and its similarities to many other philosophies. Relationship between Tao philosophy and quantum theory is also noted.
