Alongside Zheng Liangshu and Jiang Chongyue, Lundahl's scholarship, reviewing Chinese scholarship, was notable in examining authorship and dating of Han Feizi's chapters, and have still been recalled modernly.
Sima Qian presents
Han Fei as a late
Warring states period figure. Because Sima Qian only mentions a few chapters, it is not possible to outright preclude a later Han dynasty origin for the entire work, but it does not mention any Han dynasty events, or avoid any Han dynasty taboos that would prohibit a late Warring States dating. Except as compilations, some chapters would have to be at least as late as the late Warring States period. Chapters 6 and 19 recall the fall of several late Warring states period states. Chapter 6's memorial on Having Regulations recalls the fall of
Wey in 243bce. Chapter 19's Taking Measures recalls
Qin's conquest of Ye from the
Zhao, dated to 236bce. Seemingly written from the context of the late
Han state, the chapter could still conceivably have preceded Han's fall in 230bce, or that of either Zhao or Wei if they had only yet ceded territory.
Xunzi Putting aside the traditional claim of
Xun Kuang as a teacher of Han Fei, Xun Kuang is still a useful demarcation. (Parts of) the Han Feizi adapt administrative ideas from
Shen Buhai, a contemporary of
Shang Yang. It's particular "Xing-Ming" adaptation of Shen Buhai likely does post-date the
Xunzi, with the Xunzi and then Han Feizi being more technically complex. The Han Feizi is also
Shang Yang's first reference. The
Xunzi references a variety of figures, but not Shang Yang. The Han Feizi moreover dominantly develops earlier pre-Xunzi thinking. Both the Han Feizi and
Lushi Chunqiu discuss
Shen Dao, but the Han Feizi's argument has more in common with the earlier thinker. It lacks an ideological basis for more complex, late Warring States hierarchies, which the Lushi Chunqiu subsequently develops. Shen Dao wasn't very ideological either; he suggests power as a means to order as an alternative to chaos, if the ruler prefers order. He also suggests means to chaos. In this case, the Lushi Chunqiu has more in common with Xun Kuang, while the Han Feizi has more in common with the earlier Shen Dao. As argued by Tao Jiang, simply interpreting "
Han Fei" as a late student of
Xun Kuang, as according to
Sima Qian, can "distort the nature of the Han Feizi’s approach to politics, as well as misidentify (his) sources of inspiration." Although Xun Kuang views human nature as "bad", he has a more moral focus, while the Han Feizi's view of human nature as "driven by cravings for wealth and recognition" is "much more aligned with pre-Xunzi thinkers". Sima Qian also relates Han Fei with
Laozi, considering Han Fei concerned with such things as "methods and techniques of governance."
Lushi Chunqiu Although considering Shen Dao's influence clear, Eirik Lang Harris (2016) of the
Shenzi fragments did not consider it discernible whether the
Lushi Chunqiu's Shen Dao influence was adapted directly from Shen Dao, or based on writings filtered through secondary scholars, as including what is now Chapter 40 of the Han Feizi. But he considered the latter likely. If not including a basis in what is now chapter 40 itself, the Lushi Chunqiu otherwise makes it more likely that at least some of its argumentation predates it. Shen Dao saw governing the state as based in controlling the allotment of goods, preventing contention between people seeking them. Neither the Confucians, Shen Dao or Han Fei view the ruler's positional power as sufficient to determine good or ill. In principle, the Lushu Chunqiu justifies an entire hierarchy for it. Harris takes the ''Lushi Chunqiu's'' moral adaptation as resonating more with its own late
Xun Kuang era. It still adapts Shen Dao's ideas of positional power as preventing chaos, but as justifying more complex hierarchy together with a more moral justification using it to aid the impoverished. The Han Feizi doesn't simply advance Shen Dao either, and can still be considered
late. But it is more closely aligned with Shen Dai's earlier Warring States ideas in the sense of "amoral" political theory. It defends Shen Dao's "adapting to circumstances" from earlier Confucianism, taken as arguing against positional power as a tool for good or ill when used by good or bad actors. Han Fei maintains it is as insufficient to cause or solve good or ill, ruin and disaster, which in some cases is beyond human control. Positional power more simply aids the ruler in maintaining his position and order. At most, it will enable the government's adaptation to circumstances, while at worst the ruler doesn't cause ruin by himself.
Laozi commentaries Containing the earliest commentaries on the
Tao te Ching (Laozi), while early Chinese scholarship agreed with a post-Han Fei dating for the Han Feizi's Laozi commentaries Ch.20-21, later Chinese scholarship questioned a late dating with the discovery of the
Mawangdui silk texts, following
Sima Qian's assertion that Han Fei was based in
Huang-Lao. Like
Yuri Pines, Lundahl still considered a direct authorthial or ideological basis between the commentaries and Han Feizi questionable, considering them addendums. Regardless, the text's Laozi content would most likely have been added in a period when the editors thought rulers would have been interested in commentaries on Laozi. With Chapter 5 also syncretizing Laozi and
Shen Buhai, this can include the period of its writing and inclusion. Although not necessarily the "original"
Tao te Ching, the Han Feizi is probably reading from an early, less metaphysical version, like that of the Mawangdui. Less "
realist", the commentaries themselves could even be argued earlier than other parts of the Han Feizi.
Sinologist Hansen,
Tang Junyi and
A.C. Graham related the commentaries as developing out of the late Warring States
Guanzi, as including the earlier
Neiye. While it would not suggest they were written by the
Han Fei of Sima Qian, Lundalh argued they bare more resemblance to the earlier
Mencius than late Warring States
Xun Kuang or other parts of the Han Feizi, placing less emphasis on ceremony than the "innermost heart". ==Introduction==
