性樸論目前在荀學研究領域勢成燎原。相關研究對性樸論的證明可分為本證與反證兩大類：本證通過「本始材樸」等材料直接推理出先天人性呈價值中性的性樸論；反證則通過指出性惡論的內在矛盾及其與《荀子》全書的矛盾，凸顯性樸論於荀子之真實性、必要性。然相關論證均存在明顯漏洞：一方面，「本始材樸」等材料僅限定人性為自然物而非人工物，並非判定其價值狀態，故不能據此得出人性呈價值中性的性樸論；另一方面，如果不偷換荀子的概念，不曲解荀子的論證，則性惡論不僅沒有明顯的內在矛盾，也與《荀子》全書義理貫通。目前來說，性惡論依然是荀子人性論之正論。

Currently, the theory that human nature is neutral is becoming popular in the research field of Xunzi’s thoughts. The relevant research on the proof of the theory that human nature is neutral can be divided into two categories: direct evidence and indirect evidence. The direct evidence deduces the neutral human nature theory that human nature is neither good nor evil through the materials such as “the original material is artless,” and the indirect evidence highlights the necessity and authenticity of neutral human nature theory for Xunzi by pointing out the inherent contradiction of the evil human nature theory and its contradiction with the content of Xunzi. However, there are obvious loopholes in the relevant arguments: on the one hand, “the original material is artless” only defines human nature as natural object rather than artificial object, but it is not a judgment of human nature’s value state, thus the neutral human nature theory that human nature is neither good nor evil can’t be deduced from it; on the other hand, without switching the concept of Xunzi nor distorting the arguments of Xunzi, we can find that theory of evil human nature not only have no obvious internal contradictions, but also conform to the argumentation of the book of Xunzi. For the time being, the theory of evil human nature is still the correct conclusion of Xunzi’s theory of human nature.
