研究期間:10108~10207;The Gu wen shang shu (lit. ancient script Classic of Documents) was consid ered in much modern scholarship to have been fabricated by Yen Ruoqu (閻若璩), so that the works different from Yen’s opinion were often overlooked. Ho wever, debates on the Ku-wen shang-shu continued from the Qian-jia period to the late Qing. Furthermore, more recent research indicates that Yen’s opinion is debatable. This research plan will examine the development of Gu wen shan g shu studies in the late Qing, including the question of whether or not it was an authentic ancient document. I will consider this issue both in terms of the methods of inquiry and intellectual aspects. I will also consider the relations between the Gu wen shang shu question and the Han-Song Learning debate, N ew Text scholarship, and evidential scholarship (考據學).
