The problem of “Morality” was one of the most heavy topics in China in the beginning of 20th century because human nature had been imprisoned by the moral idea of old feudalism for too long time. In the whole 20th century, people constantly adjusted the relation between the morality and the human nature and try to make human nature reside poetically under the sky of morality. The conflict between human nature and social moral norms is an eternal topic accompanying the growing up of mankind, which exists for ever, and will become sharper and more evident in the tremendous changes of history. The cultural history of mankind shows us that the footsteps of human nature and morality should take each other as tropics: The establishment of moral norms should take human nature as a purpose, and the healthy development of human nature should also follow the necessary moral standards.
