本文集中讨论了金谷治和罗丹(Dan Robins)对《荀子·性恶篇》真伪的质疑。作者认为,金谷治的“苟子性朴说”混淆了“朴”字的两种词性,即名词和形容词以及形容词的两种意义,亦即描述义和评价义。而罗丹所谓的被污染过的“核心文本”可以有一种更为融贯的理解:在他看来彼此冲突的三个主题,实则层层递进,共同构成了一个完整的道德形而上学理论。成熟期的荀子道德哲学不仅对性恶有了更充分的论述,而且对人的可完善性也有了更为全面的阐述。 This article focuses on the questioning of the authenticity of “Xunzi · Evil” by Jinguji and Dan Robins. The author believes that Kimura’s “Xunzi’s sexuality theory” confused the two parts of the word “poem”, that is, the two meanings of nouns and adjectives and adjectives, that is, the meaning of righteousness and evaluation. What Rodin called “contaminated” “core texts” can have a more coherent understanding: the three themes that he seems to conflict with each other are actually progressively advanced to form a complete theory of moral metaphysics . Mature Xunzi’s moral philosophy not only has a more complete discussion of sexual evil, but also has a more comprehensive exposition of human perfection.
