本文依余嘉錫對「甭武子」之兩種理解的線索，從筆者以往掘發之兩種需武子形象「佯愚晦智」與「不避艱險」所形成之魏音人與宋儒朱熹的參照系譜出發，以作為切入余氏人賄命述的重要視窗，由是透過「從不避艱懈肪正不阿」與「從佯愚晦智到與世委蛇」這兩個面向的連結，延伸至余氏{世說新語畫畫疏〉中有關「方正不阿」及「與世委蛇」之人賄命述的探索，並由此突穎余氏畫畫疏{世說新語〉的詮釋殊趣及價值向度。經由余氏{世說新語畫畫疏〉之部分與整體的詮釋幸有昌，不僅可以進一步反省其簧疏之向度乃以宋學精神聖如台魏晉文化之得失，亦得以具體印證從「人物代稱」到「經典詮釋」之學術進路的方法效應，最後本文更將「方正不阿」及「與世委蛇」這兩種生命典型重新置於思想及文化的脈絡裡來進行反思，以充分體現筆者多年來結合人物與思想的學術關懷。

Based on Yu Jiaxi's two readings of Ning Wuzi , this article explores his discourse on people and characters by drawing upon the present author's previous studies on the two images of Ning Wuzi 一“being a wise fool" and “ bracing oneself for diHiculties. " As the author argues in previous studies, the two images together form a generic contrast to Zhu Xi and other Song Confucians. In this article , the author embarks a further investigation to trace the links between two transitions: from “ bracing oneself for diHi culties" to fangzhengbue (straightness and righteousness), and from “ being a wise fool"to yushiweishe(following the crookedness of the world) By way of reconstructing these links , the article would like to extend previous discussions to Yu's discourse on fangzhengbue and yushiweishe as embedded in his Commentaries on Shishou Xinyu. In doing so , it also intends to show Yu's interpretive strategies and vision of values From Yu's interpretative remarks in Commentaries on Shishou Xinyu , whether taken separately or as a whole , we can discern his basic interpreta tive stance -he investigated Wei-Jin culture from the perspective of Song Confucians' intellectualism. Such investigation, as argued in this article , provides a fruitful occasion for us to critically reflect on methodological issues concerning those scholarly approach的that forge links between people/characters and interpretations of classics. AII in all , this article re situates the two prototypes of beings , fangzhengbue and yushiweishe , within the contexts of philosophical thinking and cultural critique , an approach that the author has adopted in previous studies of characters and thoughts. Keywords: YuJiaxi; fangzheng (righteousness); weishe (crooked ness); characters; interpretations of classics.
