韩国友人要出版我的文集并力促我写一“思想自传”,使我陷入一种两难境地。一方面,我深感荣幸,十分高兴有机会与韩国读者交流;另一方面,我深感现在不是写“思想自传”的时候,因为我的思想远未成熟。但盛情难却,我不得不对自己思想的历程做个简要回顾。孔子曰:“四十而不惑。”? Korean friends want to publish my essays and urge me to write a “thought autobiography” that has put me in a dilemma. On the one hand, I am deeply honored and very happy to have the opportunity to communicate with readers from South Korea. On the other hand, I feel deeply that it is not the time to write “biographical thoughts” because my thoughts are far from mature. But passionate but difficult, I had to make a brief review of the course of my thoughts. Confucius said: “forty and not confused.”?
