伴隨著對文本的發掘,許多被視為理所當然的學術認知正逐漸動搖。所以如何更深入理解傳統思想與學術的複雜性,是現階段重新理董學術史的一項重要課題。以本文對俞樾的研究為例,早期的相關文獻多將焦點注意在俞樾與乾嘉考據學的關係,推崇的是俞樾著名的兩《平議》。然而俞樾卻自認為他的《湖樓筆談》、《茶香室經說》、《曲園雜纂》等書,較前者更有勝義。這些著作中充滿了對《公羊》學的討論:或是對《公羊》學的理論加以發揮,或是以《公羊》義作為其經史論斷的最後依據,與早期學者所推崇俞樾學術之重心略有出入。本文藉由俞樾對《公羊》學「王魯」之義的發揮,用以說明俞樾經學思想重心之所在,或可為傳統對俞樾之認知,作概念上的修正。
With the reading up of original texts, many doctrines about Chinese learning history which were going without saying in the past have being challenged. Now how to comprehend the complexity of the tradional thinking and learning becomes one of the essential question for discussion. This paper aims to be such an attempt. Most early studies focused on the relationship between Yu Yue and the school of textual research during Qianlong and Jiaqing periods, thus extolled his two famous books Qun Jing Ping Yi and Zhu Zi Ping Yi. However, Yu himself thought much of his other works, such as Hu Lou Bi Tan, Cha Xiang Shi Jing Shuo, and Qu Yuan Za Zhuan. From these books, it will be found that Yu Yue either exerted the theories of school of Gongyang studies, or applied them to make his final judgments in his investigations of Confucian classics and Chinese history. As a result, it presents a new emphasis of Yu's achievements different from the early reserches. This article, baese on the observation of Yu's exertion of the theory of Wang Lu, one of the key theories of Gongyang, tries to throw a light on the real focus of Yu's classics studies and make a conceptual modification on the past image of Yu Yue.
