名篇Masterpiece 劝学Encouraging Learning 修身Self-Cultivation

君子曰：学不可以已。
青，取之于蓝，而青于蓝；
冰，水为之，而寒于水。
木直中绳，輮以为轮，其曲中规。
虽有槁暴，不复挺者，輮使之然也。
故木受绳则直，金就砺则利，君子博学而日参省乎己，则知明而行无过矣。

The gentleman says: learning cannot be stopped.
Indigo is extracted from the blue plant, yet is bluer than the blue; ice is made from water, yet is colder than the water.
Wood straight to the ink-line, steamed and bent into a wheel, its curve matches the compass. Though it be parched by wind and sun, it will not straighten again—because the steaming made it so.
Thus wood by the ink-line becomes straight, metal at the whetstone becomes sharp; if the gentleman broadly learns and daily examines himself, his wisdom will be clear and his conduct without fault.

Listen

Meaning

Xunzi opens his masterwork on learning with the absolute claim that learning must never cease. Through a chain of comparisons—indigo bluer than its plant, ice colder than its water, wood bent into a wheel, wood straightened by the line, metal sharpened on the stone—he argues that study transforms nature. The conclusion: broad learning plus daily self-examination yields clarity and blameless conduct. It embodies Xunzi's Confucian belief that后天 education reshapes human nature.

君子说：学习不可以停止。靛青是从蓝草里提取出来的，却比蓝草的颜色更深；冰是由水凝结而成的，却比水更寒冷。木材笔直得合乎墨线，用火烤弯加工成车轮，它的弯曲程度就合乎圆规的标准了。即使再风吹日晒而枯干，也不会再挺直，这是因为用火烤弯曲使它变成这样的。所以木材经过墨线量过就能取直，金属拿到磨刀石上去磨就会变得锋利，君子广泛地学习而且每天检查反省自己，就能智慧明达、行为没有过错了。

Appreciation

[Plain Paraphrase] Xunzi writes Encouraging Learning: 'The gentleman says: learning cannot be stopped.' 'Indigo is extracted from the blue plant, yet is bluer than the blue; ice is made from water, yet is colder than the water'—'therefore, without accumulating small steps, one cannot reach a thousand miles; without accumulating small streams, one cannot make a river or sea'—'carve and give up, rotten wood won't split; carve and not give up, metal and stone can be engraved'—a famous exhortation to learning. [Imagery and Method] The whole uses multiple analogies to argue: five comparisons—blue and indigo, water and ice, wood and wheel, wood by the line, metal at the stone—from positive and negative sides repeat the efficacy of learning; the analogies are apt and layered. The sentence form mingles parallel and loose; 'Indigo is extracted… yet is bluer than the blue' and 'Ice is made… yet is colder than the water' form antitheses; parallelism and gradation together, the force majestic like a rainbow. [Emotion and Theme] The whole brims with warmth urging the young to strengthen themselves, raising learning to the height of human-nature reform and character completion—advocating 'learning cannot be stopped,' embodying Xunzi's Confucian spirit of 'transform nature through artifice' and valuing acquired education. [Key Lines] 'Indigo is extracted from the blue plant, yet is bluer than the blue' later condensed into the idiom 'the pupil surpasses the master,' figuratively the student surpassing the teacher, the later generation surpassing the former; 'learning cannot be stopped' became the loudest maxim in the Chinese exhort-to-learn tradition.

【白话串讲】荀子写《劝学》：“君子曰：学不可以已”。“青，取之于蓝，而青于蓝；冰，水为之，而寒于水”——“故不积跬步，无以至千里；不积小流，无以成江海”——“锲而舍之，朽木不折；锲而不舍，金石可镂”——劝学名篇。【意象与手法】全文用博喻论证：以蓝与青、水与冰、木与轮、木受绳、金就砺五组比喻，从正反两面反复申说学习的功效，喻体贴切而层递分明；句式骈散相间，「青，取之于蓝，而青于蓝」「冰，水为之，而寒于水」构成对偶，排比与层递并用，语势磅礴，气势如虹。【情感与主旨】全篇洋溢着劝勉后学、自强不息的热忱，把学习提到关乎人性改造与品格完成的高度，主张「学不可以已」，体现荀子「化性起伪」、重视后天教育的儒家精神。【名句点睛】「青，取之于蓝，而青于蓝」后世凝为成语「青出于蓝而胜于蓝」，喻学生胜过老师、后人胜过前人；「学不可以已」更成为中华民族劝学传统中最响亮的格言。

Background

Xunzi, named Kuang, a native of Zhao in the late Warring States, honored as Xun Qing, was the synthesizer of pre-Qin Confucianism, named with Mencius yet differing in thought: Mencius held human nature good, Xunzi held it evil, believing human nature inherently desirous, to be reformed by later ritually-based education. Encouraging Learning is the first chapter of the Xunzi and the most systematic and famous pre-Qin essay on learning. This excerpt is the opening, centrally arguing learning's importance and efficacy. Xunzi long lectured at the Jixia Academy in Qi, thrice its sacrificer; in late life, at the invitation of Lord Chunshen, lived in Chu and wrote tens of thousands of words. As the Warring-States world neared unity and the hundred schools contended, Xunzi opened with 'encouraging learning' precisely to establish Confucian education amid the troubled age, cultivating ritually-clear gentlemen for the unified realm. He stressed 'learning cannot be stopped'—both inheritance of Confucius's 'learn and review often,' 'learn without satiety,' and with the Warring-States' pragmatic color: he advocated 'learn until you reach ritual and stop,' learning finally pointing to ritual practice and character completion, not mere memorization. Later estimates of Xunzi vary, but his 'transform nature through artifice' educational philosophy and 'encouraging learning' tradition profoundly influenced disciples Han Fei and Li Si and the whole of Chinese educational history.

荀子，名况，战国末期赵国人，时人尊称荀卿，是先秦儒家集大成者，与孟子并称而思想相异：孟子主性善，荀子主性恶，认为人性本有贪欲，须靠后天礼义教化加以改造。《劝学》是《荀子》第一篇，也是先秦论学文章中最系统、最著名的一篇。本篇节选为开篇，集中论证学习的重要与功效。荀子长期在齐国稷下学宫讲学，三为祭酒，晚年应春申君之邀居楚，著书数万言。战国末年天下将一，各家竞相争鸣，荀子以「劝学」开宗，正是要立儒家教化于乱世，为统一后的社会培养知礼明义的君子。他强调「学不可以已」，既是对孔子「学而时习之」「学而不厌」的继承，又带战国末期的务实色彩——他主张「学至乎礼而止」，学习最终指向礼义的实践与人格的完成，而非单纯的记问之学。后世对荀子评价不一，但他「化性起伪」的教育哲学与「劝学」传统，却深刻影响了韩非、李斯等弟子，也影响了整个中国教育史。

Art

This piece is a model of pre-Qin masters' argumentative prose; artistically most outstanding is the craft of 'multiple analogies in gradation, parallel and loose complementing.' The opening 'learning cannot be stopped' states the thesis, decisive; immediately it uses two natural analogies 'indigo from blue' and 'ice colder than water' to prove from 'quality' that learning can surpass the original; then the 'wood straight to the ink-line, steamed into a wheel' processing analogy proves from 'change' that external force can reshape nature, with 'though parched, will not straighten' adding a layer emphasizing the change's irreversibility; last 'wood by the ink-line becomes straight, metal at the whetstone becomes sharp' moves from object to person, drawing the positive conclusion 'broadly learn and daily examine yourself.' The analogies draw from daily life (blue plant, ice-water, wood, metal, line, stone), plain and apt, pressing layer on layer into a tight 'analogy–proof–conclusion' logical chain. In language, parallel and loose mingle: 'Indigo is extracted… yet is bluer than the blue' is antithesis, 'wood by the ink-line becomes straight, metal at the whetstone becomes sharp' is parallel, 'if the gentleman broadly learns…' closes in loose sentence, long and short interlaced like waves stacking. The repeated use of virtual words 'then,' 'therefore,' 'yet' makes the textual breath连贯 and the turns clear. The whole uses no word of preaching, yet persuades by analogy—an eternal model of 'arguing by analogy.'

本篇是先秦诸子散文中论说文的典范，艺术上最突出的是「博喻层递、骈散相济」的章法。开篇一句「学不可以已」立论，斩钉截铁；随即连用「青出于蓝」「冰寒于水」两个自然比喻，从「质」的角度证明学习可以超越固有；再以「木直中绳，輮以为轮」的加工比喻，从「变」的角度证明外力塑造可以改变物性，「虽有槁暴，不复挺者」补足一层，强调这种改变不可逆转；末以「木受绳则直，金就砺则利」由物及人，推出「博学而日参省乎己」的正论。比喻取诸日常（蓝草、冰水、木、金、绳、砺），浅近贴切，层层逼进，形成「喻—证—结」的严密逻辑链。语言上骈散相间：「青，取之于蓝，而青于蓝」是对偶，「木受绳则直，金就砺则利」是骈句，「君子博学而日参省乎己，则知明而行无过矣」以散句收束，长短错落，如浪叠涌。虚词「则」「故」「而」的反复运用，使文气贯通、转折分明。全篇无一字说教，而以比喻服人，是「用喻论证」的千古范本。

Allusions

Though argumentative, this piece contributed a series of idioms and allusions to Chinese culture. 'The pupil surpasses the master' comes from 'indigo is extracted from the blue plant, yet is bluer than the blue,' originally figuring that one through learning can exceed the origin; later mostly figuratively the student surpassing the teacher, the later generation surpassing the former—a classic phrasing both honoring the teacher and encouraging surpassing. 'Ice colder than water' stands with 'indigo from blue,' both proving 'learning cannot be stopped.' The 'steamed into a wheel' 'steam-bend' (roasting wood to bend it) implies Warring-States craft background; ancient wheel-making needed 'compass,' 'square,' 'line,' 'ink,' so 'matches the line,' 'matches the compass' both borrow carpentry terms for analogy, showing Xunzi's pragmatic 'object-figures-principle' spirit. In 'metal at the whetstone becomes sharp,' 'whetstone' is the grindstone, with 'line' and 'compass' all craftsman's tools—five analogies all from craft, exactly the 'encouraging learning' pragmatic ground-color. The 'stop' in 'learning cannot be stopped' means 'cease'; Confucius's 'until death,' Zhuangzi's 'life has a shore yet knowledge none' all say learning has no end; Xunzi's phrase actually opens the later exhort-to-learn poetic theme—Yan Zhenqing's 'black hair knows not the early diligence,' Han Yu's 'On Progress in Learning,' Zhu Xi's 'Encouraging Learning Poem' all drank from it. As for 'daily examines himself'—'examine' (self-check) directly inherits Zengzi's 'I daily examine myself in three ways,' uniting learning and self-cultivation, becoming the classic Confucian path of 'learn to become a person.'

本篇虽为说理文，却为中国文化贡献了一系列成语典故，影响深远。「青出于蓝」出自「青，取之于蓝，而青于蓝」，原喻人经学习可超过本原，后世多喻学生胜过老师、后辈胜过前辈，成为尊师重教又鼓励超越的经典表述；「冰寒于水」与「青出于蓝」并举，同证「学不可以已」之理。「輮以为轮」的「輮」（用火烤使木弯曲）暗含战国工艺背景，古代制轮需「规」「矩」「绳」「墨」，故「中绳」「中规」皆借木工术语立喻，体现荀子「以物喻理」的务实精神。「金就砺则利」中「砺」为磨刀石，与「绳」「规」一样都是匠人工具，五喻皆取自匠作，正是「劝学」务实的底色。「学不可以已」的「已」训「止」，孔子「死而后已」、庄子「生也有涯而知也无涯」皆言学无止境，荀子此语实开后世劝学诗文的母题——颜真卿「黑发不知勤学早」、韩愈《进学解》、朱熹《劝学诗》无不受其沾溉。至于「日参省乎己」之「参省」（检验反省），直承曾子「吾日三省吾身」，把学习与修身合一，遂成儒家「学以成人」的经典路数。

Commentary

Encouraging Learning is the opening, principle-establishing first chapter of the Xunzi and the first systematic essay on learning in Chinese educational thought—its place never replaced. This excerpt states with 'learning cannot be stopped,' using five analogies to prove learning's efficacy, logically tight, diction concise and strong, long selected into various classical anthologies and textbooks, a must-read entry to pre-Qin masters' prose. Tang's Han Yu wrote 'On the Teacher,' Song's Zhu Xi compiled 'Encouraging Learning Poem,' even the Three-Character Classic's 'jade unworked, not a vessel; man untaught, not know righteousness' can be seen as Xunzi's 'encouraging learning' tradition's offspring; 'indigo from blue' and such became daily idioms, entering the whole people's vocabulary. Later estimates extremely high: Qing's Liu Xizai's Arts Outline said Xunzi's prose 'principle admirable and diction elegant'; modern saying of pre-Qin prose often sets Encouraging Learning beside the Mencius and Zhuangzi, calling it 'words near yet meaning far, seeing principle through analogy.' In intellectual history, Xunzi's 'transform nature through artifice' advocating acquired learning to reform human nature stands with Mencius's good-nature theory as the two pillars of Chinese educational philosophy; 'learning cannot be stopped' stressing 'lifelong learning' still has strong practical meaning today. The whole does not flaunt talent but approaches with plain analogies layer on layer—exactly the Xunzi-school pragmatic, earnest, thick style.

《劝学》是《荀子》开宗明义第一篇，也是中国教育思想史上第一篇系统论学的专文，其地位千古不替。本篇节选以「学不可以已」立论，用五组比喻论证学习之功效，逻辑严整、文辞简劲，历来被选入各种古文选本与语文教材，是先秦诸子散文入门必读。唐人韩愈作《师说》、宋人朱熹辑《劝学诗》，乃至《三字经》「玉不琢，不成器；人不学，不知义」，都可视为荀子「劝学」传统的流裔；「青出于蓝」等语更成为日常成语，进入全民语汇。后世评价极高：清人刘熙载《艺概》称荀子之文「理懿而辞雅」；今人论先秦散文，多以《劝学》与《孟子》《庄子》并举，谓其「言近旨远、以喻见理」。就思想史而言，荀子「化性起伪」主张后天学习改造人性，与孟子性善论双峰并峙，共同构成中国教育哲学的两大支柱；「学不可以已」对「终身学习」的强调，在今天仍有强烈的现实意义。全篇不矜才使气，而以平实比喻层层逼近，正见荀学务实笃厚之风。

Prosody

Form Pre-Qin masters' prose · argumentative form (unrhymed prose, not verse)先秦诸子散文·论说体（散体文，非韵文）

Rhyme The whole is unrhymed, belonging to non-rhymed prose yet possessing its own inner rhythm. Its antithetical lines like 'Indigo is extracted from the blue plant, yet is bluer than the blue; ice is made from water, yet is colder than the water' and 'wood by the ink-line becomes straight, metal at the whetstone becomes sharp' are word-for-word parallel, matched in syllables, ringing when read; the anadiplosis of 'blue / blue,' 'water / water' adds a ballad-like flowing turn.全文不押韵，属无韵之散体，而句内自具节奏。其对偶句如「青，取之于蓝，而青于蓝；冰，水为之，而寒于水」「木受绳则直，金就砺则利」，字字相对、音节相称，读来铿锵；「蓝／蓝」「水／水」的顶真回环，更有歌谣式的流转感。

Tone pattern The sentence form mingles parallel and loose, long and short interlaced. The opening loose sentence states the thesis, short and forceful; the middle's 'yet'-linked compound sentences unfold in gradation, the force gradually rising; the close's threefold 'then' rises like steps, closing in a long line, the aftertone unceasing. Throughout it is governed by meaning, the breath turning with the analogy, no rhyme yet forming its own rhythm—a model of pre-Qin argumentative prose's 'breath full, words fitting.'句式骈散相间、长短错落。开篇散句立论，短促有力；中段以「而」字连接的复句层递展开，语势渐张；结尾「则」字三叠，如级级登高，收束于长句，余响不绝。通篇以意驭气，气随喻转，无韵而自成节律，是先秦论说文「气盛言宜」的典范。

Reading note This piece is unrhymed prose; its musicality lies not in sound-rhyme but in the rhythm of sentence form and the rise-fall of tone. Xunzi's prose is famed for 'strict diction, tight principle, full breath, straight reason'; Encouraging Learning's opening especially shows its strength: the thesis sentence is short and forceful ('learning cannot be stopped' five characters a beat), the analogy sentences antithetically neat ('indigo from blue,' 'ice colder than water'), the gradation sentences use virtual words 'yet,' 'then,' 'therefore' to carry breath, read like watching water's momentum—first a trickle (two analogies), then a torrent (the wheel-bending analogy), finally converging into a flood (the broad-learning self-examination argument). This 'rhyme-without-rhyme' is exactly the unique beauty distinguishing pre-Qin prose from later parallel prose; its repetition and anadiplosis ('bluer than blue,' 'colder than water' turning back) add a 'sing three times' cadence, so for a thousand years it is recited unceasingly, a model for classical-language teaching recitation. The loose sentences' spaciousness and the paired sentences' neatness interweave, making the whole see proportion amid irregularity, like drum-beats dense and sparse; reciting it is fluent, memorizing it easy—its vocal-teaching merit also beyond later parallel prose.本篇为无韵之散文，其音乐性不在声韵，而在句式的节奏与语气的起伏。荀文以「辞严义密、气盛理直」著称，《劝学》开篇尤见其长：立论句短促有力（「学不可以已」五字一顿），比喻句对偶工整（「青出于蓝」「冰寒于水」），层递句以「而」「则」「故」等虚词贯气，读之如观水之势——初则涓涓（两个比喻），继则滔滔（輮轮之喻），终则汇为洪流（博学参省之论）。这种「无韵之韵」，正是先秦散文区别于后世骈文的独特美感；其重言与顶真（「青于蓝」「寒于水」之回环）更添一唱三叹之致，故千百年来传诵不衰，成为文言教学诵读的典范。而散句之疏朗与偶句之整饬交错成文，更使全篇于参差中见匀称，如鼓点之疏密相间，诵之琅琅、记之易成，其声教之功，亦非后世骈文所能及。

Line by line

君子曰：学不可以已。

The gentleman says: learning cannot be stopped.

君子说：学习不可以停止。

The gentleman says: Learning may not be stopped.

开篇一句立论，是全文的总纲。「君子曰」三字表明以下所论是君子之道，为全篇定下庄重基调；「学不可以已」五字斩钉截铁，正面提出中心论点。其妙处在一「已」字——学习不是「当学」「须学」，而是「不可以已」，「已」训「止」，以否定句式写出绝对性，杜绝任何懈怠的余地。这句平语却有无穷力量：它把学习从一时一事的功课提升为终身不辍的生存方式，与孔子「学而时习之」、曾子「日三省吾身」一脉相承。全文种种比喻、层层论证，无不是这句话的展开与证明，可谓「一句立骨、万喻归宗」。

The opening line states the thesis, the whole's framework. 'The gentleman says' three words marking that what follows is the way of the gentleman, setting the grave tone; 'Learning must never cease' five words clipped, the central proposition stated directly. Its genius lies in the word 'cease' - learning is not 'should learn,' 'must learn,' but 'may not cease,' 'cease' meaning 'stop,' the negative sentence writing the absoluteness, leaving no room for slack. This plain sentence holds infinite force: it raises learning from the task of a moment to a lifelong way of being, in the line of Confucius' 'learning and often practicing' and Zengzi's 'daily thrice self-examining.' All the later metaphors and layered arguments are the unfolding and proof of this one line - 'one sentence raising the bone, ten thousand metaphors returning to the root.'

青，取之于蓝，而青于蓝；冰，水为之，而寒于水。

Indigo is extracted from the blue plant, yet is bluer than the blue; ice is made from water, yet is colder than the water.

靛青是从蓝草中提取的，却比蓝草更青；冰是由水凝结成的，却比水更寒冷。

The blue dye is drawn from the indigo plant, yet it is bluer than the plant; ice is made from water, yet it is colder than water.

两个自然比喻并举，从「质」上证明学习可以超越本原。「青」指靛青染料，「蓝」指蓝草，靛青出于蓝草而颜色更深；冰出于水而温度更低——两个喻体都取自然的「生于彼而胜于彼」，喻意明确：人天生资质有限，但经过学习、加工，可以超越原来的自己。对偶句式「取之于蓝，而青于蓝」「水为之，而寒于水」工整对称，读来朗朗上口，先「出」后「胜」的层递关系一目了然。尤妙在「而」字的转折，轻轻一转，便点出「学」使质变的关键。此二句后世凝为「青出于蓝而胜于蓝」的成语，喻学生胜过老师、后人超越前人，其生命力至今不衰。

Two natural metaphors set together, proving on 'substance' that learning can surpass the origin. 'The indigo' the indigo dye, 'the indigo plant' the liao grass, the dye from the plant yet deeper in color; ice from water yet colder - both images taking nature's 'born of that yet better than that,' the meaning clear: man's native endowment limited, yet through learning and shaping he can surpass his original self. The couplet 'taken from the indigo plant, yet bluer than the plant' and 'made from water, yet colder than the water' neatly paired, the cadence easy, the layer of 'issued from' then 'surpassed' clear. Especially fine the turn of 'yet,' a light turn marking the key that learning changes the substance. These two lines later condense into the idiom 'indigo drawn from the indigo plant yet surpassing it,' for the pupil outdoing the teacher, the later age outdoing the former, its life undimmed to this day.

木直中绳，輮以为轮，其曲中规。虽有槁暴，不复挺者，輮使之然也。

Wood straight to the ink-line, steamed and bent into a wheel, its curve matches the compass. Though it be parched by wind and sun, it will not straighten again—because the steaming made it so.

木材笔直合乎墨线，用火烤弯曲做成车轮，其弯曲就合乎圆规；即使晒干枯槁，也不再挺直，这是因为火烤使它变成这样。

Wood straight as the carpenter's line can be steamed and bent into a wheel, its curve fitting the compass; though it be sun-dried and shrunken, it will not straighten again - the shaping has made it so.

这一层由「质」进到「变」，证明外力加工可以彻底改变物性。木材本直，经「輮」（火烤弯曲）而成轮，且「虽有槁暴，不复挺者」——即使日晒干枯也不再复原，说明这种改变是根本性、不可逆的。三句以木工术语立喻，「中绳」「中规」暗含规、矩、绳、墨的匠作背景，喻体来自日常劳作，亲切而有力；「輮使之然也」一句以判断句式点破因果，强调「使之然」——正是外力（学习教化）在起作用。比喻层层逼进：青出于蓝是「胜于本原」，木变为轮是「改其本性」，二者合证学习不仅能增益知识，更能重塑人格，为下文「君子博学」的结论张本。

This layer advances from 'substance' to 'change,' proving that external shaping can thoroughly alter a thing's nature. Wood, originally straight, steamed and bent ('rou') into a wheel, and 'even if it dries and cracks, it will not straighten again' - even sun-dried it will not return, showing the change is fundamental, irreversible. Three lines taking carpentry terms for metaphor, 'true to the line' and 'true to the compass' holding the carpenter's background of compass, square, line and ink, the image from daily labor, familiar and forceful; 'the bending has made it so' a judgment sentence pointing the cause, stressing 'made it so' - precisely the external force (learning and teaching) at work. The metaphors press layer on layer: indigo from the plant is 'better than the origin,' wood to wheel is 'changing its nature,' the two together proving learning can not only add knowledge, but remake character, priming the later conclusion of 'the gentleman wide in learning.'

故木受绳则直，金就砺则利，君子博学而日参省乎己，则知明而行无过矣。

Thus wood by the ink-line becomes straight, metal at the whetstone becomes sharp; if the gentleman broadly learns and daily examines himself, his wisdom will be clear and his conduct without fault.

所以木材经过墨线量过就能取直，金属拿到磨刀石上磨就会锋利，君子广泛学习并且每天检查反省自己，就能智慧明达、行为没有过失。

Thus wood measured by the line is straight, metal laid to the grindstone is sharp; the gentleman, broad in learning and daily examining himself, becomes clear in wisdom and faultless in conduct.

这是全篇的结论，由物及人、由喻入理。「木受绳则直，金就砺则利」以两个对偶比喻收束前文——绳（墨线）使木直，砺（磨刀石）使金利，正如学习使人明；由此自然推出「君子博学而日参省乎己，则知明而行无过矣」的正论。「博学」言其广，「日参省」言其勤且恒，「知明而行无过」言其果——学、省、行三者环环相扣，构成完整的修养程序。「参省」直承曾子「吾日三省吾身」，把学习与内省合而为一。句式上「则」字三用，如阶梯层层抬升，语势直贯而下；「知明而行无过」六字更以知与行的并举，点明学习最终指向实践，是「学以致用」的儒家命题。

This is the whole's conclusion, from thing to man, from metaphor to principle. 'Wood laid to the line becomes straight, metal laid to the whetstone becomes sharp' two couplet metaphors closing the above - the line (carpenter's mark) making wood straight, the whetstone making metal sharp, as learning makes man wise; hence the natural deduction, 'the gentleman, wide in learning and daily searching himself, becomes wise in understanding and blameless in conduct.' 'Wide in learning' its breadth, 'daily searching' its diligence and constancy, 'wise and blameless' its fruit - learning, self-search, conduct, the three linked in a ring, a complete program of cultivation. 'Searching himself' directly inherits Zengzi's 'daily thrice self-examining,' fusing learning and inner search. In syntax the word 'then' used thrice, like steps rising, the force straight down; 'wise in understanding and blameless in conduct' six words setting knowing and doing side by side, pointing that learning at last turns to practice, the Confucian proposition of 'learning applied.'

Study

Word focus

已 Yǐ (stop, cease): the key word establishing the whole essay's thesis. 'Cannot be stopped' stated in negative tone is more absolute than 'should learn' or 'must learn'—learning is not an optional choice but an unavoidable necessity. The word also implies a temporal dimension: to stop is to ruin, not to stop is to advance, as Confucius's 'in learning, like one who fears he will not catch up, yet fears to lose it.' Later 'learning has no end' and 'strengthen oneself ceaselessly' are of one lineage. Once this word appears, the whole essay's urgency and solemnity stand forth, and all analogies (indigo, wheel-bending) are set around 'not stopping'—only unceasing learning can surpass the original and remake nature. One word 'stop' is the most concise expression of the pre-Qin exhort-to-learn tradition. 「学不可以已」之「已」，训「止」，是全文立论的关键一字。「不可以已」以否定语气出之，比「当学」「须学」更具绝对性——学习不是可学可不学的选择，而是不可终止的必然。「已」字亦暗含时间维度：止则废，不止则进，正如孔子「学如不及，犹恐失之」。后世「学无止境」「自强不息」皆与之一脉相承。此字一出，全文的紧迫感、庄重感立现，而「青出于蓝」「輮以为轮」诸喻，无不围绕「不已」而设——只有不停的学习，才能超越本原、重塑本性。一个「已」字，是先秦劝学传统最凝练的表达。

青 Qīng (indigo / blue): appears twice with different senses—the first 'qīng' is the indigo dye, a noun; the second 'qīng' is adjective, the depth of color. One word two uses, noun-adjective turning, the sentence compact and its sharpness self-revealing. 'Indigo from blue' thus became a thousand-year idiom, figuratively the pupil surpassing the teacher, the later wave pushing the former. In classical Chinese, 'qīng' spans blue, green, black; here specifically the dark-blue indigo, opposed to the 'blue plant,' exactly taking its 'deeper than the origin' sense. Xunzi uses the plainest dyeing craft for analogy, showing his aptness in choosing analogies; and 'indigo from blue' turning from philosophic proposition to daily idiom shows the phrase's deeply-rooted power. 「青，取之于蓝，而青于蓝」中，「青」字两见而意各不同：前一「青」指靛青染料，为名词；后一「青」作形容词，言颜色之深。一字二用、名动相转，句式紧凑而机锋自见。「青出于蓝」由此成为千古成语，喻后学超越师承、后浪推前浪。在古汉语中，「青」兼指蓝、绿、黑诸色，此处特指靛青（深蓝色），与「蓝草」相对，正取其「深于本原」之义。荀子以最浅近的染色工艺立喻，足见其取喻之贴切；而「青出于蓝」由哲学命题化为日常成语，更可见此句深入人心的力量。

輮 Róu (steam-bend): pronounced/tong 'rou' (to bend by softening), means roasting wood with fire to bend it—the key craft of Warring-States wheel-making. Xunzi uses 'róu' for analogy, its subtlety in the sense of 'changing nature yet not returning': 'though parched by wind and sun, it will not straighten again—because the steaming made it so.' This one word holds three layers: first, the action of external force (fire), figuratively learning's necessary education; second, the thoroughness of qualitative change—'will not straighten again' says the change is irreversible; third, the 'made it so' causation, emphasizing that acquired shaping decides what a person becomes. The carpenter's 'róu' and education's 'learn' are unrelated, yet Xunzi takes it at hand to make a thousand-year wonderful analogy—exactly his pragmatic wisdom of 'object-figures-principle.' 「輮以为轮」之「輮」，通「揉」，指用火烤使木弯曲，是先秦制轮的关键工艺。《荀子》以「輮」字立喻，妙在其「改变本性而不复返」的意味——「虽有槁暴，不复挺者，輮使之然也」。这一字包涵三层意思：一是外力（火）的作用，喻学习教化之必须；二是质变之彻底，「不复挺」言改变之不可逆；三是「使之然」的因果，强调后天的塑造决定人成为何物。木工之「輮」与教化之「学」本不相干，荀子信手拈来，便成千古妙喻，正见其「以物喻理」的务实智慧。

参省 Cān xǐng (examine oneself): old commentary reads 'cān' as 'three,' meaning examine oneself several times daily, or trains it as 'inspect and investigate'—both readings cohere and are near in meaning. This phrase directly inherits Zengzi's 'I daily examine myself in three ways,' placing 'learn' and 'examine' side by side: broad learning is the expansion of 'knowing,' self-examination is the checking of 'conduct,' the two together forming the complete cultivation routine. Echoing 'learning cannot be stopped,' 'daily examines' is exactly the concretization of 'not stopping'—done daily, then it is 'not stopping.' Xunzi especially marks 'examine,' showing his advocated learning is not memorization but the self-cultivation of unity of knowledge and action with constant introspection—also the essence of Confucian 'learn to become a person.' 「日参省乎己」之「参省」，旧注或读「参」为三，谓每日多次反省，或训为检验考察，两说皆通而意近。此词直承曾子「吾日三省吾身」，把「学」与「省」并举：博学是「知」的扩充，参省是「行」的检视，二者合而为人格修养的完整功夫。与「学不可以已」呼应，「日参省」正是不已的具体化——每日行之，方为不已。荀子特标「参省」，说明他主张的学习不是记问之学，而是知行合一、随时内省的修身之学，此亦儒家「学以成人」的精义所在。
