Sun Qing and Xunzi: The Lineage of Thought in the Context of Western Han Historiography

Brief Introduction

"Sun Qing" refers to Xunzi, the prominent philosopher of the late Warring States period, whose personal name was Kuang and who was respectfully addressed as Sun Qing. In the Book of Han (Hanshu), Ban Gu did not establish an independent biographical entry for him; instead, he situated him within the analytical discourse of chapters such as the Treatise on the Five Elements (Wuxing Zhi), focusing on his political philosophy of "being clear about the Royal Way" (Wangdao) and "deliberating on the severity of punishments." This record not only confirms Xunzi’s position within the Han dynasty’s intellectual genealogy but also reveals how his theories transitioned from pre-Qin Confucianism to pragmatic legal and institutional construction, serving as a critical key to understanding the Han dynasty’s governing principle of "virtue as primary, punishment as auxiliary."

Core Knowledge Points

1. The Evolution of Names and Titles
Xunzi, with the surname Xun and given name Kuang, was referred to in historical records as "Sun Qing." The mainstream academic view suggests that during the Warring States period, there may have been a phonetic shift between the surnames "Sun" and "Xun," or that his ancestors had received enfeoffment from the Sun clan. Ban Gu, in the Book of Han, adopted the nomenclature found in Sima Qian’s Records of the Grand Historian (Shiji), reflecting the Han historians’ systematic organization and standardization of titles for pre-Qin figures. This detail underscores the rigor and evolutionary trajectory in how early historiography identified individuals.

2. The Political Ideal of "Being Clear About the Royal Way"
Although Xunzi is often viewed as representing a later phase of Confucianism, he vigorously advocated for governance through a combination of ritual (li) and law (fa). The phrase "being clear about the Royal Way" refers to his profound insight that the foundation of state governance lies in order and moral instruction. Unlike Mencius’ theory of "innate goodness," Xunzi argued for "innate evilness," thereby emphasizing the necessity of constraining human nature through external "rituals" and internal "laws." This line of thought provided theoretical support for centralized authority, asserting that a ruler must possess a clear strategy for governing the realm (the Royal Way) to maintain social stability.

3. Legal Innovation through "Deliberating on the Severity of Punishments"
This is the most controversial yet practically significant aspect of Xunzi’s philosophy. He did not oppose the use of punishment; rather, he insisted that punishments must be just, moderate, and consistent. He proposed the principle of "dual efficacy of punishment and reward," arguing that heavy penalties for minor crimes would induce fear rather than genuine submission among the populace, while light penalties for grave crimes would fail to curb malicious behavior. His nuanced discussion on the proportionality of punishments directly influenced the drafting principles of the Han dynasty’s Nine Statutes (Jiu Zhang Lü), laying the early theoretical foundation for the principle of "proportionality between crime and punishment" in ancient Chinese law.

Connection with the Content of the Book of Han

In the Treatise on the Five Elements of the Book of Han, Ban Gu cites Sun Qing’s perspectives to explain the relationship between celestial omens and political affairs. He uses Xunzi’s thought as a reference point to evaluate Dong Zhongshu’s theory of "Interaction Between Heaven and Mankind." For instance, when discussing whether natural disasters directly correspond to the faults of officials, the Book of Han, borrowing Sun Qing’s voice, emphasizes that disasters are largely reflections of the clarity of governance (whether the Royal Way is being implemented) rather than simple punitive actions by heaven.

Additionally, the Bibliographical Treatise (Yiwen Zhi) in the Book of Han classifies Xunzi’s works under the Confucian category. Although the entry is concise, it established his official orthodox status. Through this classification, Ban Gu implies that Xunzi was a pivotal figure in the Confucian transition from "speculative philosophy" to "practical application." For subsequent generations, the image of Sun Qing in the Book of Han is no longer that of a mere scholar of the Jixia Academy, but rather a bridge connecting pre-Qin philosophy and Han Confucianism. Reading the discussions on Sun Qing in the Book of Han, we perceive not only the transmission of individual thought but also a historical microcosm of how ancient Chinese political philosophy moved from idealism toward a compromise and fusion with realism.
