What Is Shu: Twice in the Analects, and Once Without the Word

Shu (恕, fourth tone) is the word Confucius gives when Zigong asks for one word he can practise for his whole life: 己所不欲，勿施於人, “what you do not want, do not do to others.” The rest of the answer suits a smaller page than most quote sites offer. The word occurs twice in 492 passages, both times because a disciple asked, and the Chinese edition most people download prints one of those two wrongly.

What is shu inside Confucius’s own book is a smaller object than the version circulating on quotation sites. Search the bare word and you may mean an Egyptian god of air, an ancient state in Sichuan, a Japanese coin, three universities, or — in Confucius‘s own source text — the title of Book VII. This page is about 恕, the ethical term, and it says early which shu it isn’t.

What is shu

Zigong asks for one word. Confucius answers with eight characters, and then supplies the gloss himself.

“Is there one word which may serve as a rule of practice for all one’s life?” The Master said, “Is not RECIPROCITY such a word? What you do not want done to yourself, do not do to others.”
— Analects 15.24 · 子貢問曰：「有一言而可以終身行之者乎？」子曰：「其恕乎！己所不欲，勿施於人。」 · trans. Legge, 1861

恕 — shù. Xu Shen’s Shuowen Jiezi glosses it as 仁也 and reads the graph as 从心如声, the heart radical below and 如 above as the phonetic. Take your own heart as the measure.

忠 — zhōng, its partner word, used eighteen times in the same book. Zhu Xi’s commentary draws the usual line: 盡己之謂忠，推己之謂恕, doing your utmost is loyalty, extending it outward is shu.

己所不欲，勿施於人 — the eight-character rule Confucius attaches to the word. It appears twice, and only one of those times next to the word itself.

Legge capitalised RECIPROCITY, and that one capitalised word carries most of how English now writes about shu. It is worth knowing what he didn’t reach for. Across the 20 books of his translation he uses forgiveness zero times, empathy zero times, and the phrase “golden rule” zero times.

Which shu did you mean? Six candidates sharing one syllable

Read this before anything else, because most pages ranking for “shu” are disambiguation lists that name the candidates and answer none of them.

Shu the Egyptian deity belongs to another language family entirely. Nothing here concerns it.

The table exists because the Analects contains its own second shu. Legge’s contents name Book VII “SHU R.” after opening chapter 述而不作, “a transmitter and not a maker.” Same syllable, different graph, and not the word handed to Zigong.

One sentence, two homes, and only one contains the word

The line everyone quotes appears twice, and the two appearances answer different questions.

At 12.2 the question is about ren. Chung-kung asks what humaneness is, and gets a list: behave as if receiving a great guest, employ people as if assisting at a sacrifice, then 己所不欲，勿施於人. No resentment in the state, none in the family. The word 恕 doesn’t occur.

At 15.24 the question is narrower and larger at once: is there one word to carry for a lifetime. Here the word is present, with those eight characters as its gloss.

Legge translated the identical line two ways, which is easy to miss:

“It is, when you go abroad, to behave to every one as if you were receiving a great guest; to employ the people as if you were assisting at a great sacrifice; not to do to others as you would not wish done to yourself.”
— Analects 12.2 · 己所不欲，勿施於人 · trans. Legge, 1861

The same eight characters arrive as “not to do to others as you would not wish done to yourself” at 12.2, and as “What you do not want done to yourself, do not do to others” at his 15.23. Two quote sites can look like they carry different sayings. They carry one sentence, and only one of its two homes holds the term.

The Stanford Encyclopedia of Philosophy’s entry on Confucius treats all three spots as a group, quoting “Do not impose upon others those things that you yourself do not desire” at 12.2 and pointing on to 5.12 and 15.24. In the version I read, revised May 2024, it never uses the term shu once. The leading English reference work discusses the sentence without the word that most quotation pages use to name it.

Twice for shu, eighteen for zhong: what the book spends its words on

I counted the Chinese rather than trusting the summaries, and the results aren’t what the secondary literature implies.

Twenty books, 492 passages, and the word a man is told he can practise all his life occurs twice. Ren occurs 110 times across those same passages, li 75 times, and zhong 18 times. If frequency tracks emphasis, shu is among the quietest items in a book that otherwise repeats itself freely.

That isn’t a reason to dismiss it. It can equally mean that when the word is used, everyone present already knew what it meant and needed nothing beyond the eight characters. Both readings stay open, and the second is why the definition has been argued over since rather than simply inherited.

One more count, for anyone checking the arithmetic: Project Gutenberg’s Chinese edition (#23839) prints 15.24 as 其怒乎, substituting the graph for anger. Legge’s own edition sets the Chinese beside his translation as 【廿三章】…子曰、其恕乎、己所不欲、勿施於人, so two independent copies disagree, and the one with the radicals intact is Legge’s. Count 恕 mechanically in #23839 and you get one. Count it in a corrected text and you get two. Either way, eighteen against two is the ratio against its partner word. That gap is unresolved in Confucianism itself: commentaries from the second century on write as if shu were central, and the early text doesn’t.

Zigong proposes the same rule and is told he hasn’t reached it

There’s a third version, and most quote collections skip it.

“What I do not wish men to do to me, I also wish not to do to men.” The Master said, “Ts’ze, you have not attained to that.”
— Analects 5.12 · 子貢曰：「我不欲人之加諸我也，吾亦欲無加諸人。」子曰：「賜也，非爾所及也。」 · trans. Legge, 1861

Zigong states the principle in his own words and in the reverse direction: not what I impose on you, but what you mustn’t impose on me. Confucius cuts it off. 非爾所及也.

Two things follow. Shu isn’t primarily the word for what you’re owed; this book runs it from what you’re about to do, outward. And the text will tell a named disciple that stating the rule and living it are different achievements, which is the part a wall poster leaves off. The positive counterpart sits at 6.30, where Legge has the humane man “wishing to be established himself, seek also to establish others,” with the method named straight after: judging others by what is near at hand in yourself is the art of humaneness. The Chinese is 能近取譬, and it occurs once.

Why “reciprocity” is a translator’s choice rather than the meaning

Search any page about shu and “reciprocity” arrives within the first sentence. It comes from exactly one place.

In Legge’s 1861 translation (#4094), the string RECIPROCITY appears once, capitalised, at the moment Confucius answers Zigong. Lowercase reciprocity appears nowhere else in those 20 books. Nor does forgiveness, empathy, altruism or sympathy. When he comes to the other occurrence, at 4.15, he doesn’t use it at all:

“Shan, my doctrine is that of an all-pervading unity.” The disciple Tsang replied, “Yes.” … Tsang said, “The doctrine of our master is to be true to the principles of our nature and the benevolent exercise of them to others, — this and nothing more.”
— Analects 4.15 · 子曰：「參乎！吾道一以貫之。」曾子曰：「唯。」…曾子曰：「夫子之道，忠恕而已矣。」 · trans. Legge, 1861

See what happens to 忠恕 there. It becomes two clauses about the same person’s sincerity and its extension outward, close to what Zhu Xi said eight centuries earlier, and nowhere near “reciprocity.” Nor does he use the word at 12.2, where those same eight characters turn up unlabelled. One capitalised word in Book XV became the standard English for a term that resists a single noun.

Modern Chinese applies the other pressure. 寬恕 means forgiveness, so it’s natural to read the classical word through the modern one. Nothing in the text supports it: both occurrences concern acting before the fact, and neither involves a plea for leniency. Nothing in the text forbids it either, and Zhu Xi’s 推己 is itself a Song reading rather than a Han one.

Four claims about shu that the text does not say

Every one of these is repeated by quotation sites, and the first three are also repeated by people who should know better. See Fake Confucius Quotes for the lines themselves; this is about the claims wrapped around them.

“Confucius said his Way was zhong and shu.” He didn’t. Zengzi said it, after Confucius had left the room. The master’s own words at 4.15 are 吾道一以貫之, “my Way has one thread through it,” and he walks out without explaining the thread. When Confucius uses 一以貫之 again at 15.3, the subject isn’t ethics: he is denying that he is merely a man who has learned and remembered a great deal.

“Shu is the Confucian golden rule.” The comparison is ours, not the text’s, and it does work the text declines. The Analects version is negative. Matthew 7:12 is positive. The positive form does exist in the same book at 6.30, and there it attaches to ren.

“These passages are securely his.” The Stanford Encyclopedia notes that read as abstract imperatives, they differ from the exemplar-based talk around them, and that some scholars, E. Bruce Brooks among them, take them as interpolations. I could not verify Brooks’s argument against the manuscript evidence from here and am not endorsing it. It is nonetheless a named position in the field, and a page that hands over 15.24 as the master’s key without saying so isn’t reporting what specialists think.

“My edition says 15.23, so you’ve misnumbered it.” Neither of us has. Legge numbers the chapter XXIII inside Book XV; modern standard numbering calls it 15.24. The Chinese file at Gutenberg is worse: it numbers 21 twice in Book XI, 5 twice in Book XII, and merges what should be two chapters at the head of Book XV, so nothing cited from it should go unchecked against a second copy.

Questions People Ask About Shu

What is shu in Confucianism?
Shu (恕) is the word Confucius offers at Analects 15.24 for one principle a person can practise all his life: 己所不欲，勿施於人, what you do not want done to yourself, do not do to others. It appears twice in the book, once in Zengzi’s summary at 4.15 and once at 15.24, where Confucius names it himself.

Where does Confucius define shu?
Twice, depending on what counts. At 15.24 he names the word and supplies eight characters. At 12.2 the identical eight characters answer a question about ren, with no word attached. A third version at 5.12 has Zigong propose the principle himself, and Confucius replies 非爾所及也, you have not attained to that.

Is shu the same as the Golden Rule?
No, and the difference is grammatical mood. The Confucian form is negative, forbidding what you’d refuse yourself; Matthew 7:12 instructs positively. The positive counterpart exists in the same book at 6.30 and attaches to ren. Calling 15.24 the golden rule imports a comparison from outside the text.

Does shu mean forgiveness?
Modern Chinese 寬恕 does, which makes the reading tempting. Nothing in the Analects supports it: both occurrences concern acting before the fact, and no one asks to be excused. Legge uses forgiveness zero times. Zhu Xi’s own gloss is 推己, extending what you have outward, which is a different thing.

How many times does shu appear in the Analects?
Twice in a corrected text, at 4.15 and 15.24. Project Gutenberg’s Chinese edition (#23839) prints 15.24 as 其怒乎, substituting the graph for anger, and a mechanical count of that file returns one. Legge’s edition prints 其恕乎 in the Chinese beside his translation.

Why do some pages cite this Confucius quote as 15.23?
Editions number it differently. Legge’s 1861 translation calls the chapter XXIII inside Book XV, while standard modern numbering calls it 15.24. The Chinese file at Gutenberg duplicates several chapter numbers and merges others, so its internal numbering can’t be trusted for citation.

If shu is central, why is it mentioned so rarely?
Two answers, and the evidence doesn’t settle between them. Either the word was ordinary enough in that circle to need no explaining, or the passages are late additions, which is what E. Bruce Brooks argues and what the Stanford Encyclopedia records. Neither reading supports treating 15.24 as the summary of a system the text argues out 110 times under another name — which is one reason “what is shu” keeps getting answered with a single sentence and no count.
