Can every statement in the Biography of Diviners be attributed to Sima Qian?

The answer first: no

No. First ask who speaks and whom they report. The Biography of Diviners layers three voices: the story of Sima Jizhu, the Grand Historian’s comment, and Master Chu’s later recollection. Reading them as one and assigning everything to Sima Qian is a mistake. This is the chapter’s most essential reading lesson.

The mistake is understandable: the chapter flows continuously and “The Grand Historian says” can resemble a single author’s signature. Yet another speaker appears. Master Chu begins with “your servant” and describes what he saw while a palace gentleman. The voices are distinct.

First layer: Sima Jizhu’s Chang’an debate

The opening is brief: Sima Jizhu came from Chu and practiced divination in Chang’an’s Eastern Market. Song Zhong and Jia Yi then leave for the same day’s bathing leave, visit the divination shop in rainy weather, and hear Jizhu speak thousands of words, all apparently well reasoned. Setting, demeanor, and dialogue belong to this narrative layer.

The debate is its center. Song and Jia ask why he occupies such a low place and practices such a defiled occupation, treating divination as socially despised. Jizhu replies at length, drawing on Laozi’s statement that highest virtue does not display itself as virtue and Zhuangzi’s account of the noble person free from inner anxiety about hunger and cold, defending divination. These are Jizhu’s attributed words preserved through a recorder.

The narrative also supplies an ending. Song later returns from an unfinished mission to the Xiongnu and is convicted. Jia becomes tutor to Prince Huai of Liang; after the prince dies falling from a horse, Jia stops eating and dies in grief. The historian adds that these men pursued blossoms while severing roots. Appearances and endings remain within this story layer.

Second layer: “The Grand Historian says”

The shift rests on one sentence: ancient diviners mostly did not appear in written chapters, but when it came to Sima Jizhu, “I recorded and wrote about him.” The first-person “I” identifies the Grand Historian explaining why this chapter was written: he made a record of Jizhu.

Weigh that statement carefully. The verb here means recording or describing, not delivering a value judgment. It explains why he wrote, rather than guaranteeing every claim’s correctness. Assigning every investigation and judgment in the whole chapter to Sima Qian begins to go wrong at that point.

Third layer: “Master Chu says”

“Master Chu says: When your servant was a palace gentleman, I traveled through Chang’an.” Once “your servant” appears, the speaker has changed. This section is recollection: he describes seeing learned diviners adjust their clothing and caps properly, then discusses Jizhu’s knowledge of the Changes and techniques associated with the Yellow Emperor and Laozi.

The final marriage-date story is especially easy to misattribute. Chu says that while a palace gentleman he shared an office with men awaiting appointment under the Grand Diviner. An office colleague told him that, under Emperor Wu, specialists gathered to judge whether a certain day was suitable for taking a wife. The Five Phases specialist said yes; the geomancy specialist no; the Establish-and-Remove specialist inauspicious; the Congchen specialist gravely inauspicious; the calendar specialist slightly inauspicious; the Heaven-and-humanity specialist slightly auspicious; and the Taiyi specialist highly auspicious. Unable to settle the dispute, they submitted it to the emperor, who ordered that fatal taboos be avoided and the Five Phases taken as primary. The account passes through at least two hands—an official awaiting a Grand Diviner appointment, then Chu, then the reader. It is not Sima Qian’s eyewitness report at Emperor Wu’s court.

The passage gives a reported conclusion only. It supplies no expanded ruler-minister dialogue or street-scene details, so stop where the text stops rather than embellish. The bounds of the report are the bounds of this evidence. Other sources are needed to investigate actual practice under Emperor Wu; here we have one secondhand recollection.

Three steps: identify the voice before reading an old book

First locate the markers. “The Grand Historian says” and “Master Chu says” divide speakers. Switch mental channels before reading onward, so Chu’s recollections do not become Sima Qian’s statements.

Second distinguish narrative, quotation, and report. Direct narration, attributed character speech, and secondhand recollection carry different evidential weight. Jizhu’s debate is quoted speech; the marriage story is reported information. They should not be cited as equivalent evidence.

Third, name the section when quoting: say it comes from the Master Chu section’s report or from the Grand Historian’s comment, so readers can identify the voice instead of hearing only “the Records says.”

One final limit: this chapter alone cannot resolve every debate about the book’s composition, authenticity, or supplements, and each passage should not be assigned dogmatically to an author. The specialists’ disagreement concerns differences in divination rules, rather than a scientific test. It is no recommendation to choose your own wedding date from the story.
