Abstract: As a pioneer in learning, spreading, and utilizing modern scientific psychology in modern China, Mr. Fu Ssu-nien has been neglected by psychological researchers for many years. In 12 years of studying on psychology, Mr. Fu wrote and translated several philosophical monographs to illustrate his psychological views, such as Introduction to psychoanalysis, Group Psychology, and Hsing Ming Ku-Hsǔn Pien-Cheng. Based on these efforts, Mr. Fu made a profound analysis of the Chinese traditional view of human nature, the trend of scientism in modern psychology, the psychoanalytic thought of psychoanalytic school, and then judged that the modern Chinese psychological research would eventually become scientific. Moreover, Mr. Fu summarized barriers of development of mass mind from three aspects including society, family and individual, and then generated and advocated a basic view of humanity containing effort, sense of discipline, the concept of rational and health. Furthermore, working together with Cai Yuan-Pei, Wang Jing-Xi, Tang Yue, and Su Xiang-Yu, Mr. Fu devoted to the early construction of the discipline of psychology and promoted the development of scientific psychology in modern China.
