The postface to the
Kongzi Jiayu asserts that it was compiled by
Kong Anguo, an influential scholar and descendant of Confucius who lived in the 2nd century BC, from actual recordings of Confucius' sayings made by his disciples. Soon after Wang Su, who was a critic of the scholar
Zheng Xuan, published his version of the
Jiayu, Ma Zhao (馬昭), a follower of Zheng, declared that it had been "amended and enlarged" by Wang. Despite lingering doubts about its authenticity, the
Jiayu was influential throughout the
Tang and
Song dynasties.
Sima Zhen, author of an important commentary to
Sima Qian's
Shiji, valued it as highly as the
Shiji itself.
Zhu Xi, the leading
Neo-Confucianist, also held it in high regard. A new rationalist intellectual movement,
Han learning, gained influence during the
Qing dynasty and began a thorough criticism of the
Kongzi Jiayu and other purportedly authentic ancient works. A large number of scholars, including Sun Zhizu (孫志祖), Fan Jiaxiang (范家相), Yao Jiheng (姚際恒), Cui Shu (崔述), Pi Xirui (皮錫瑞), Wang Pinzhen (王聘珍), and
Ding Yan, all reached the same verdict that the
Jiayu was a forgery. Sun and Fan both wrote detailed analyses supporting their conclusion. Although the
Jiayu had its defenders, represented by Chen Shike (陳士珂), they were a small minority. In the 20th century,
Gu Jiegang, the leading force of the highly influential
Doubting Antiquity School, reaffirmed the Qing scholars' conclusion that the
Kongzi Jiayu was a forgery by Wang Su, and called it "worthless" for the study of Confucius. As a result, few modern scholars studied the work. However this view, would later be overturned by archaeological discoveries. ==Western scholarship==
