《荀子》成書於戰國後期。時當百家爭鳴，《荀子》篇章多針對諸家學説加以評論，包括儒家、墨家、道家等，尤以《非十二子》、《天論》、《解蔽》最爲明顯，痛陳利弊。前賢學者多就以上篇章對《荀子》與諸子關係作出研究，至於其他篇章，則所論甚少。本文以《荀子》與《老子》、《莊子》進行文本比對，以三書罕見的相合詞彙爲切入點，透過文本、詞彙比對，以嶄新的分析角度，重探《荀子》各篇與《老子》、《莊子》的關係，提出新的看法，從而探究荀子如何取捨老、莊學説。

Xunzi was written during the late Warring States period. Most of the chapters in Xunzi comment on Confucianism, Mohism, and Daoism, etc. The most remarkable ones are ＂Fei shi er zi＂非十二子, ＂Tian lun＂天論, and ＂Jie bi＂解蔽. Most of the existing academic researches on the relationships between Xunzi and the other works of pre-Han philosophers focus on these three chapters without paying much attention to the rest. This thesis compares the texts and the uncommon lexicons in Xunzi with Laozi and Zhuangzi. It aims at examining how Laozi and Zhuangzi, helped formulate the philosophical ideas stated in Xunzi.
