Abstract: From the perspective of the “concern for the times”, we can see an inherent problem in Fung Yu-lan’s system of “New Principle Learning”, i.e., the incoordination between the progressive view of history (Xin Shilun) and the transcendent sphere of Heaven and Earth (Xin Yuanren). This dates back to the divergence between the progressive Dao and the eternal Whole in Xin Lixue. This incoordination is embodied obviously in the argumentative difficulty of “revolutionary morals”. It reminds us that a common dilemma in modern China is also in Fung, that is, the dilemma of the “motivation of action to progress the history” and the “commitment of a present perfection”. Fung gradually inclines to the latter. However, the issue itself is still significant today.
