Mencius once said that if you read a person's poems and books without knowing the person behind them, then you still have not truly understood them.

That idea matters especially when approaching the Shiji (Records of the Grand Historian). To understand why this book was written, why it is unlike other histories, and why later generations placed it so high, it helps to begin with Sima Qian himself: what kind of man he was, what sort of family shaped him, what age he lived in, and what he had to endure in order to finish his work.

Much of this can be pieced together from two texts associated with him: the final chapter of the Shiji, the "Self-Preface of the Grand Historian," and his famous letter, Reply to Ren An. Taken together, they reveal not just a historian, but a man carrying family duty, intellectual ambition, humiliation, grief, and an almost frightening determination.

A family that lived inside history

In his self-preface, Sima Qian traces his ancestry far back into antiquity. He presents the Sima lineage as one that had long been associated with astronomy, geography, and historical recordkeeping. By the Zhou period, the family had become keepers of the royal archives. Later, as the house of Zhou declined, different branches scattered into the states of Wei, Zhao, and Qin.

Among his ancestors in Qin was Sima Cuo, a figure known in early history. Subsequent generations also served in office. By the time of the Han, this family tradition had not disappeared. Sima Qian's father, Sima Tan, held the office of Grand Historian under Emperor Wu of Han.

This is important because the Shiji was never just a private literary project. It grew out of an inherited vocation. In Sima Qian's own understanding, recording the past was not merely scholarship; it was the continuation of a family charge that had stretched back for centuries.

The education that formed him

Sima Qian says that he was born in Longmen, in what is now Hancheng in Shaanxi. He grew up in a setting tied to farming and herding by the Yellow River region. Yet he was no ordinary child. By the age of ten, he was already reciting ancient texts. The wording here suggests more than basic literacy: not simply learning to read, but committing the old writings to memory. Even by demanding standards, that is remarkable.

At twenty, he traveled widely. He went south through the Jiang and Huai regions, reached Kuaiji, searched out the legendary tomb of Yu, looked toward Jiuyi, and moved along the Yuan and Xiang rivers. He also traveled north across the Wen and Si rivers, studied in the cultural centers of Qi and Lu, and observed the lingering traditions associated with Confucius. He passed through many places before eventually returning and serving at court as a gentleman attendant. Later he was sent on official missions westward and southward, including into Ba, Shu, and the regions of Qiong, Zuo, and Kunming.

These journeys mattered immensely. Travel gave him something books alone could not: a sense of terrain, customs, memory, ruins, and local traditions. For a historian trying to write across centuries and states, that experience was invaluable.

It is easy for modern readers to overlook how difficult learning was in his time. Books were written on bamboo slips. Large texts were physically heavy. Many pre-Qin works had already been lost or scattered, especially after the destruction of books in earlier eras. Access to texts was itself a privilege. Sima Qian, being born into a learned household and the family of a high official, was in a far better position than most. Ordinary people had little chance of reading widely under such conditions. Educational inequality, which people speak of so often now, was hardly a modern problem.

He also did not grow up without guidance. Although the self-preface does not dwell on every detail, later tradition associates him with Dong Zhongshu as a teacher. Whether one focuses on that or on his father, the larger point remains the same: Sima Qian was carefully cultivated from a young age. Sima Tan did not simply wish his son to become great. He prepared him for a task he himself could not complete.

That, to me, is one of the most striking things in this story. People often speak of hoping their children will achieve something extraordinary, but hope alone means little. What matters is teaching, example, discipline, and transmission. Sima Tan did not merely dream that his son would continue his work; he raised him to do so.

Why the Shiji had to be written

The decisive turning point came near the end of Sima Tan's life. When Emperor Wu went to Mount Tai for the feng and shan sacrifices, Sima Tan was unable to accompany the imperial entourage. This weighed heavily on him. Sima Qian later writes that his father died in anger and frustration, and that he met him between the Luo and Yellow rivers after returning from a mission.

There, Sima Tan grasped his son's hand and wept. He reminded him of the family's ancient role as historians and officials of celestial matters. He feared that the line of transmission would break with him. He told Sima Qian that when he himself died, his son must become Grand Historian and must not forget what he had long wanted to write.

What he said was not merely personal. It was also historical. In his view, several centuries had passed since Confucius compiled the Spring and Autumn Annals. During the age of warring states and mutual annexation, historical records had been scattered, lost, or broken off. Now, with the Han empire having reunified the realm, there were enlightened rulers, worthy ministers, loyal subjects, and men who died for principle. If such things were not recorded, then the chain of history itself was being abandoned.

Sima Qian bowed his head in tears and promised that, though he was not especially gifted, he would set down the old traditions arranged by his forebears and leave nothing out.

That promise sits at the heart of the Shiji. The book was not born from idle ambition. It came out of an unfinished charge passed from father to son, and out of a conviction that the historian had a duty to preserve the moral and political memory of the age.

Filial piety, fame, and the burden of living on

One line from Sima Tan's words deserves special attention:

Filial piety begins with serving one's parents, continues in serving one's ruler, and is completed in establishing oneself. To make one's name known to later generations and thereby bring honor to one's parents—this is the highest form of filial piety.

This is not a small statement. It describes a hierarchy of values. Caring for one's parents is one level. Serving the ruler is another. But the highest form is to establish a name that will endure after death, so that one's parents are honored through the greatness of what one became.

Whether one fully agrees with that idea is another matter. But it is hard not to keep returning to it while reading both the Shiji and Sima Qian's letter.

Take the story of Boyi and Shuqi, for instance. Their father wanted to install Shuqi, but after the father's death, Shuqi yielded to Boyi and Boyi refused because he wished to honor the father's command; both fled, and the people instead set up the middle son as ruler. Yet the middle son barely survives in memory, while Boyi and Shuqi, who gave up power and starved on Mount Shouyang, became enduring moral figures.

That raises a harsh historical truth: if a person's life leaves no real mark on the moral imagination or historical course of later generations, even rulership may not preserve their name. By contrast, those who never sat on a throne may outlive kings.

Something similar appears in the story of Taibo and Zhongyong in the house of Zhou. They fled to the southern regions, cut their hair, and tattooed their bodies so as to remove themselves from succession and allow their younger brother Jili to inherit, ultimately paving the way for King Wen of Zhou. By conventional standards, cutting the hair and altering the body violated a duty owed to one's parents. Yet in another sense, they did it precisely to realize their father's wish. Is that not also a higher kind of filial act?

The Shiji is full of such tensions. Sima Qian himself is one of them. To suffer castration was, in the eyes of his culture, a profound disgrace to one's ancestors and family. That was unfilial in one sense. But if by enduring it he completed a book that would carry his family's name into all later ages, then perhaps it was also the highest filial act. The same ambiguity appears in figures like Wu Zixu: abandoning immediate forms of duty in order to fulfill a deeper one.

The Shiji constantly forces these questions. It does not make moral life simple. It shows that duty often comes divided against itself.

Was he writing to praise the Han—or to record the world?

At one point, Sima Qian recounts a question put to him: Confucius wrote the Spring and Autumn Annals because he lived in a time without a true enlightened ruler and had no position from which to act directly. But now, under a sagely emperor, with institutions in order and offices functioning, what exactly was Sima Qian trying to accomplish by writing history?

His answer is revealing. He rejects the idea that history exists only to criticize. In his view, different classics arose in response to different ages: the Changes with Fuxi, the Documents with Yao and Shun, poetry praising the greatness of Tang of Shang and King Wu of Zhou. The Spring and Autumn Annals did indeed commend the good and censure the bad, but not merely as satire. Historical writing, as he understood it, preserves virtue, records achievement, and makes great deeds known.

He also states his official responsibility plainly. Having served as Grand Historian, if he failed to record the enlightened virtue of the emperor, the accomplishments of meritorious ministers, the lineages of great houses, and the deeds of worthy men, then he would be guilty both before history and before his father's dying instructions.

This is what he says. Yet when one actually reads large portions of the Shiji, the impression can be more unsettling. Good deeds are not absent, but the book is crowded with ambition, betrayal, fratricide, patricide, deception, cruelty, and political violence. That is not because Sima Qian was obsessed only with ugliness. It is because if one attempts to write history truthfully, one quickly discovers how much of human history is made of things people would rather not celebrate.

The few morally tidy episodes are the ones everyone already knows. The rest is often darker. That darkness is part of what makes the Shiji feel alive.

The humiliation that defines his character

To understand Sima Qian as a person, nothing is more important than the circumstances behind Reply to Ren An.

During the Li Ling affair, Sima Qian spoke in Li Ling's defense before Emperor Wu. For this he was sentenced to death. Under Han law, capital punishment could sometimes be commuted, but only through payment or by accepting castration. Lacking the means to ransom himself, and not yet having completed his great historical work, he chose castration in order to live.

Later, his friend Ren An was imprisoned and faced execution in the aftermath of another political case. Ren An wrote to him asking for help, hoping he might intercede. Sima Qian's reply became one of the most painful self-revelations in classical prose.

In that letter, he speaks of moral cultivation, generosity, righteousness, a sense of shame, and the establishment of one's name as the traits by which a gentleman can stand in the world. Then he turns sharply to his own condition. There is no disgrace, he says, worse than what comes from desire for advantage; no sorrow worse than heartbreak; no conduct uglier than bringing disgrace on one's forebears; and no humiliation greater than castration.

He piles example upon example to show how, throughout history, association with eunuchs was treated as degrading. Confucius left one state after seeing its ruler ride with a eunuch. Worthies were alarmed when men of standing gained access through such figures. To be classed with them was a source of shame from antiquity onward.

This matters because Sima Qian is not writing abstractly. He is explaining why he cannot simply take up Ren An's request and recommend worthy men at court. How could the world accept the recommendation of someone already reduced, in its eyes, to the status of a eunuch?

He then arranges forms of humiliation in ascending order and says castration is the lowest and worst of all. In his world, an educated gentleman was expected to preserve moral dignity even at the cost of life. From that standpoint, many of his contemporaries would have regarded him as doubly laughable: reckless enough to defend Li Ling, and then too afraid to die honorably when punishment came.

What is striking in the letter is how fully aware he is of this judgment. He repeatedly uses the language of ridicule. He speaks of becoming an object of laughter, of being looked at with derision, of bringing disgrace upon his family and ancestors. He says that whenever he thinks of this shame, sweat soaks his back and clothing. He feels he has no face to visit the graves of his parents.

This is not rhetorical decoration. It is the emotional center of the letter.

And yet he refuses to explain himself away with elegant language. He says plainly that no amount of ornamented self-defense would persuade the vulgar world. It would only bring further humiliation.

Then comes the line everyone remembers:

Though death comes to all, it may be weightier than Mount Tai or lighter than a feather; the difference lies in what one dies for.

This is not a slogan in his case. It is the key to why he endured what he endured. He insists that people naturally fear death and care for parents, relatives, wife, and children. Only when driven by principle do they act otherwise. He does not pretend to be beyond fear. He even calls himself weak and desirous of life. But he also says he knows the difference between what one should accept and what one should reject. If he chose to go on living in filth and disgrace, it was not because he clung blindly to life. It was because something remained unfinished in his heart, and he could not bear the thought of dying without making his writing known to posterity.

To explain himself, he lists earlier figures whose great works emerged from suffering: King Wen in imprisonment developing the Changes; Confucius under distress composing the Spring and Autumn Annals; Qu Yuan in exile producing the Li Sao; Zuo Qiuming blind and writing the Discourses of the States; Sun Bin mutilated yet setting out military writings; Han Fei imprisoned in Qin. The point is not self-glorification. It is that frustration, blockage, injury, and exclusion have often driven extraordinary people to set down what history would otherwise lose.

At last he states his purpose directly: if he can complete this book, store it away in famous mountains, and transmit it to those who will carry it to the great cities, then he will have repaid the debt of his former disgrace. Even if he were to suffer ten thousand punishments after that, he would have no regret.

So was Sima Qian simply afraid to die? No. The letter makes clear that survival was the price he paid for finishing something he thought more important than his own bodily integrity or reputation.

His literary power

Even if Sima Qian had written only Reply to Ren An, he would still deserve a place in literary history. The letter is often regarded as one of the greatest in all Chinese prose, and it is easy to see why. It combines moral argument, personal confession, historical comparison, and unbearable sincerity.

Writing moves people most deeply when two things are present: truth and pain. The letter has both. Sima Qian does not pose as serene, detached, or invulnerable. He tells the reader the thing he can hardly bear to say about himself. That is why the letter remains so devastating.

His achievement in the Shiji is different but equally extraordinary. He is a master of narrative angle and characterization. The same person can look entirely different depending on where in the book you meet him. Liu Bang, for example, appears in one place with the dignity suitable to an imperial founder, but elsewhere the reader can clearly see his cunning, ruthlessness, and opportunism. Sima Qian does not flatten people into moral labels. He lets character emerge across scenes, voices, and conflicting perspectives.

Later critics recognized this immediately. Ban Gu praised him as possessing the qualities of a true historian: clear in wording, substantial rather than florid, straightforward in style, solid in facts, neither praising falsely nor concealing evil. Han Yu counted him among the very best writers of the Han. And the judgment modern readers know best is Lu Xun's: the supreme masterpiece among historians, and an unwritten Li Sao.

That line endures because it captures both sides of him. He was a historian, yes—but also a writer whose history carries grief, outrage, moral tension, and personal fate within it.

What kind of person was Sima Qian?

If I had to answer briefly, I would say this: he was a man of inherited duty, broad learning, literary genius, severe self-consciousness, and terrifying endurance.

He was not simply a court historian compiling records. He was someone raised inside a family vocation and entrusted with a mission at his father's deathbed. He was not simply a scholar reading books. He traveled widely, observed the world, and absorbed regional memory. He was not simply a moralist praising good rulers. He understood that honest history must also preserve ugliness, violence, weakness, and contradiction. He was not simply a victim of punishment. He was someone who endured unbearable shame because he believed an unfinished book mattered more than his own honor in the eyes of his contemporaries.

That is why later generations have admired him almost without reservation. People may argue over details in the Shiji, or over the exact degree of factual certainty in ancient history, but it is hard not to feel the difference between a work written under such pressure and a standard official history composed mainly to glorify a reigning order.

No one can prove that every line in the Shiji is completely accurate. No serious reader should make that claim. But a book produced through the lifelong labor of a father and son, and completed through suffering that almost no one would willingly choose, has a moral weight that cannot be dismissed casually.

There is also a final irony in Sima Qian's own words. He says that countless rich and powerful people are forgotten, while only extraordinary individuals are remembered. That has turned out to be true of him. Many rulers, nobles, and officeholders from his age survive only as names or not even that. Sima Qian, who accepted degradation in order to write, remains alive wherever history is read seriously.

For that reason alone, he deserves not just admiration, but respect of the deepest kind.
