魏晉玄學家的注釋學中，以王弼注《老》及郭象注《莊》最為著名。兩位思想家皆以注釋方式，詮釋先秦道家著作，並進而開展自己的哲學思想。「性情」則是攸關自然與人文世界，非常重要的論題。因此，本文以此為題，論述王弼與郭象在性情論上的主張，並據此論其在詮釋的進路中，在貼合文本的注釋中，當周旋於文本與義理之間時，其詮釋進路的差別。這一差別可謂其詮釋之方法學的差異，王弼是以「無」為方法，展現其「全」的可能性以論性情，郭象則以「有」的方式展現其「自然」之性情觀。

Wang Bi’s commentaries of Laozi and Guo Xiang’s annotations of Zhuangzi were the most well-known among others in the Wei-Jin Dynasties. They both annotated the pre-Qin Taoists works before developing their own philosophies. As “nature and feeling” is a vital issue concerning both the physical and the human world, this article would address Wang’s and Guo’s opinions on the theories of nature and feeling and accordingly remark on the differences between their approaches. Their differences lie in their methodologies. Wang showed the possibility of “the Whole (quan, 全)” to discuss nature and feeling by means of “nihil (wu, 無),” while Guo showed the view of “being itself (zi ran, 自然)” on nature and feeling by means of “existence (you, 有).”
