I want to explain the basic characteristic of Tang, Jun-Yi's cultural theory in this article. It's ”standing ren-ji(人極) to bildung the world”. The researching clues are the history of modern thoughts and Tang, Jun -Yi's life history. First, I explain some life experiences to prove the existence of 'Ren-ji(人極)'. Second, I show the affirming and the limits of the world from the developing of 'Ren-ji(人極)'. Then we can see the ideas of Tang, Jun -Yi's cultural developing. So we can illustrate the characters of Tang, Jun-Yi's cultural theory. They are moralism, idealism and humanism.
