Taiwan, as a part of the Chinese land in the recorded history, was open to the Western world in the Great Navigation Period from 4 centuries ago under the name of Formosa. The political thoughts of Western Christianity as well as the Indian Buddhism, and Chinese Confucianism & Taoism did play important roles influencing Chinese thinkers in the past. They all together had formed many rich and special styles that made the studies of them a tough job. There have been numerous scholars, however, devoted their energies discovering the nature of them in Taiwan since her restoration to China 1945 to 2008. That four generations can be told was discovered by the author in this article in which a special background of Christian Western democracy in the Taiwanese political thought was acknowledged and placed in mind for evaluation. The article discovered that from the last four generations of the studies, an overwhelming trend of the Chinese traditional 'demo fundamentalism (民本)' has its deep and common roots in the mind of the three thousand years thinkers. And Professor Sun Kwang-De was patterned to represent and describe in depth the fact of this difference from the Western thinkers who all conclude the indispensability of 'demo-cracy (民主)'. Professor Sun Kwang-De was aware of it and made his most important speech to remind the world that, based on his understanding of the long tradition of the Chinese political thought, democracy is nothing but also a kind of political myth. This article tells the details of his reasons, as well as a general introduction of the four generations in Taiwan.
