《老子》和《庄子》是我国先秦文学史上极其重要的两部著作,具有不可替代的地位。对它们的研究浩如烟海,但以往的研究关注的都是老庄之间的联系,对二者之间的差别探究过少。本文想谈一谈老庄在文本和思想方面的细微变化。 “Lao Tzu” and “Zhuang Zi” are extremely important two books in the history of pre-Qin literature in our country and have irreplaceable status. The research on them is magnificent, but the previous researches focus on the relations between Lao Zi and Chuang Zhuang, and the exploration of the difference between them is too little. This article wants to talk about the subtle changes in Lao-Zhuang’s texts and thoughts.
