Abstract
In 1925, I went to Yanjing University to teach courses in the history of Chinese philosophy. It was from this period on that I began to seriously study the history of Chinese philosophy. At the time, this was not what I really wanted to do. I had originally wanted to work with bourgeois philosophy in preparation for founding a system of my own. To work in the history of Chinese philosophy was at the time, I felt, a kind of academic duty, a kind of burden. But after working with it for awhile, I felt that there was also much that could be done in this field of the history of Chinese philosophy. That is to say, while lecturing on the history of philosophy, I also found it possible to develop my own idealist philosophical thought
