The Pragmatism prevailed because of the promotion of Changzhou School, and it was so glorious that it became a leading thought in later academic circles. Traditionally, it is thought that the Pragmatism, which was accepted by such scholars as Gong Zizhen and Wei Yuan, was the inheritance of the New Text Confucianism advocated by the Changzhou School. The Pragmatism then developed into a leading thought during the time of Empire Dao Guang. However, the academic circles always avoid mentioning the relationship between the two thought. Actually, Bao Shichen acted as an intermediary who transferred the Changzhou School＇ s thought to Gong Zizhen, Wei Yuan and other scholars, and the latter three contributed a lot to the prevailing of the Pragmatism around the period of Opium War.
