方东树(1772—1851)是清代“桐城派”文学家,史乘立传,都把他归入《文苑》之列。可是,由于方氏曾撰著了一部名为《汉学商兑》的思想学术性著作,因此许多有关清学史的论著,都不能不提及其人其书。不无遗憾的是,提及大多为一笔带过,鲜有稍详其说者。笔者孤陋寡闻,惟知建国以来除侯外庐的《中国思想通史》最后一卷中立有篇幅不长的一节外,别的专论至今未见。所以,对这部曾在清代学界引起过不大不小震动的著作,进行一番研究,或许还有必要。 Fang Dongshu (1772-1851) was a writer of the “Tongcheng School” in the Qing Dynasty. His history and biography were classified as “Wenyuan”. However, since Fang had written a scholarly book entitled “Sinology and Merchants”, many of his books on the history of the Qing History can not but be mentioned. Not without regret, most of the mentions are referred to, and there is little to say about them. The author ignorant, but since the founding of the PRC in addition to Hou Wailu Hou “General History of Chinese thought,” the last volume of neutral lengthy section, the other monographs so far have not seen. Therefore, it is perhaps necessary to carry out some research on this book which has caused minor or major shocks in the academic circles of the Qing Dynasty.
