||The thesis analyzes the origin of Chen Ting-zuo’s Yi thoughts from his writings of Da-Yi-Ze-Yan (The opinions of the Yi thoughts), Yi-Ton (Understanding of the Yi) and Du-Yi-Guan-Jian (Sights when reading the Yi). Besides, it also builds up his Shi-Zhong theory (the principle of obeying the mean) by his rectification to Fo (Buddha) and Lao (Lao-tzu). Moreover, by holding his thoughts of “enhancing the moral philosophy and keeping up the humanity”, the thesis also excavates the principles and meanings of his Yi writings, and discusses his theories of Tian-Dao (moral philosophy of the universe), humanity and practices.
There are eight chapters in the thesis. The first one is constituted by the research motive, methodology, and literature review. “Chen Ting-zuo’s autobiography” in Chapter 2 draws the outlines of his study and behavior by introducing his family background, relationship with Yen-Lee school of thoughts, associations and academic writings. “Ting-zuo’s thoughts of the Yi” in Chapter 3 probes into the origin and understanding of his Yi philosophy and discusses his practice-oriented point of view. In Chapter 4, “the moral philosophy of Ting-zuo’s Yi thoughts”, the author uses Wan Chuan-shan’s theory of “unity in two extremities” to establish firmly that Quan Kun (heaven and earth) is the rim to make the universe alive and kicking, and Yi Jian (simple) is the principle part to make the universe concord and harmonic. In view of the above, the author again uses Zen Chun-Hai’s “natural theory of the three changes in the universe (flexibility of mutuality, equilibrium of macro-coordinance , and rounding of circulation” to assure Ting-zuo’s moral philosophy in his writing, “Cho Yi.” In Chapter 5, “The humanity in Ting-Zuo’s Yi thoughts”, two of Ting-zuo’s theories, “unity of life” and “humanity thoughts”, are discussed to reveal the value of unit. “Practice of Ting-zuo’s Yi thoughts” in Chapter 6 illustrates that there is only one “heart” in Ting-zuo’s point of view. Human heart, moral heart, universe principle and human desire are all doctrines and will be unified back to universe morality and principles and make the humanity completed. Chapter 7, “the Shi Zhong theory of Ting-zuo’s Yi thoughts”, discusses his thoughts to Buddha, Lao-tzu and the crux of Wan Dao’s (the operation of politics) obstacle, and thus he brings up the Shi Zhong theory to make Wan Dao possible. Finally, a summary of the thesis and self-criticism in Chapter 8 is proposed to make it completed.
