This article contemplates Mencius’s theory of Ceyinzhixin in cultural philosophical perspective, and attempts to discuss the philosophical therapism of that time and ponders on its significance. In terms of Confucianism, Ceyinzhixin has often been a main topic of discussion as a Clue of Ren in ethics. However, considering its concepts and implications in cultural philosophical perspective, Ceyinzhixin originally implies numerous meanings such as ‘psychological condition’, ‘moral feelings’, and ‘political awareness’, and typical cultural symbolic meanings which reflect distinctive cultural mental structures of ancient China - such as ‘Ruzheruzheng’, ‘Rubaochizi’, ‘Minzhifumu’, ‘Youhuanyishi - are deeply projected on its origins and background. Therefore the concept of Ceyinzhixin was created from creatively fusing these ancient cultural traditions with the spirit of the times Mencius faced. The reason Mencius newly established his theory of Ceyinzhixin within existing cultural traditions and symbolic meaning systems is because he tried to secure an ideological basis to effectively persuade the ruling class of his times, who were into incorrigible moral corruption and political irresponsibility. Moreover, it was for the ruling class to pacify the minds and care for the survivals of the people with Renzheng who were suffering from the long wars and economical·political chaos. In these aspects, Mencius’s theory of Ceyinzhixin takes on kinds of cultural philosophical contents and characteristics; its ideology and alternative aspects are based on the ‘cultural philosophical therapism’ which try to actively repair the distorted mind-states and political awareness of the ruling class.
