入德之門的經典奠基：

二程與朱熹以《大學》為修德根本的深度理論研究

The Classical Foundation of the "Gateway to the Virtue Realm of Sagehood ": An In-depth Theoretical Study on the Cheng Brothers and Zhu Xi Taking The Great Learning as the Fundamental Basis for Moral Cultivation

一、核心前提：理學視域下“入德之門”的本質內涵與成聖目標

I. Core Premise: The Essential Meaning of the "Gateway to the Virtue Realm of Sagehood " and the Goal of Sagehood from the Neo-Confucian Perspective

欲釐清《大學》何以成為入德之門，必先界定二程、朱熹語境中“入德之門”的核心要義。所謂“入德”，並非淺層的道德行善，而是凡人轉聖賢、氣質變化、復歸天理本體的終極修為；所謂“門”，是成聖之學的入門正軌、必由路徑、工夫準則，是區別於空寂虛妄、偏執形器的正統儒學修德通道。

To clarify why The Great Learning became the Gateway to the Virtue Realm of Sagehood, one must first define the core meaning of "Gateway to the Virtue Realm of Sagehood " in the discourse of the Cheng brothers and Zhu Xi. "Entering virtue" does not mean superficial moral conduct or doing good deeds, but rather the ultimate cultivation through which an ordinary person transforms into a sage, alters his physical nature, and returns to the original substance of Heavenly Principle. The "gate" is the correct entrance, the necessary path, and the standard of practice for the learning of sagehood, a gateway to orthodox Confucian moral cultivation distinguished from the empty stillness and false illusions, or the biased clinging to concrete forms and implements.

朱熹畢生參悟程子之學，最終凝練出“涵養須用敬，進學則在致知”的入德核心工夫，明確指出此二語為“入德之門無逾於此”。同時，朱熹深刻反思當世學弊：宋世學者或流於佛老空寂之學，空談義理而無實操；或滯於形器功利，拘於書本字句而無德性體悟，二者皆不得聖門修德之正途。而“入德之門”的核心訴求，是解決學人不知修德路徑、工夫偏廢、內外割裂的根本問題，為“學為聖賢”提供可落地、可次第、可精進的完整體系。

Zhu Xi devoted his entire life to comprehending the learning of the Cheng masters and finally condensed the core practice of entering virtue: "For self-cultivation one must use reverence; for advancing in learning, the key lies in extending knowledge," explicitly stating that no other words surpass these as the "Gateway to the Virtue Realm of Sagehood." At the same time, Zhu Xi profoundly reflected on the scholarly maladies of his time: Song scholars either drifted into the empty and tranquil learning of Buddhism and Daoism, engaging in empty talk of principles without real practice, or stagnated amidst concrete implements and utility, restricting themselves to the words and phrases of books without moral experience. Neither group obtained the correct path of moral cultivation in the Confucian school. The core appeal of the "Gateway to the Virtue Realm of Sagehood " is to solve the fundamental problems of learners not knowing the path of moral cultivation, practicing one aspect to the neglect of another, and severing the inner from the outer, thereby providing a complete system that is practicable, sequential, and allows for sustained advancement for "learning to become a sage."

在理學的成聖體系中，聖賢並非遙不可及的境界，而是人人可學、步步可至的人格目標。其核心踐履次第貫穿始終：以格物致知開啟認知之基，以誠意正心夯實心性之本，以修身立己達成德性自足，以齊家治國平天下實現德性外化，最終完成個體德性與天地天理的合一。這一完整的成聖邏輯，唯有《大學》可以完整承載，這也是二程、朱熹舍諸經而獨尊《大學》為入德第一門徑的根本前提。

In the Neo-Confucian system of attaining sagehood, the sage is not an unreachable realm but a personality goal that everyone can learn to achieve and can reach step by step. Its core sequence of practice runs throughout: starting with investigating things and extending knowledge to lay the cognitive foundation, proceeding to making the will sincere and rectifying the mind to consolidate the root of mind and nature, achieving self-perfection in virtue through self-cultivation, and realizing the externalization of virtue through regulating the family, governing the state, and bringing peace to the world, and finally completing the unity of individual virtue with Heaven, Earth, and Heavenly Principle. This complete logic of sagehood can be fully borne only by The Great Learning, which is also the fundamental premise for why the Cheng brothers and Zhu Xi rejected other classics and uniquely honored The Great Learning as the foremost gateway for entering virtue.

二、根本性理論問題：二程、朱熹擇定《大學》為“入德之門”的核心緣由

II. Fundamental Theoretical Issue: The Core Reasons Why the Cheng Brothers and Zhu Xi Selected The Great Learning as the "Gateway to the Virtue Realm of Sagehood "

縱觀程朱理學體系，二人尊崇《大學》、將其定為聖門入德正途，並非經典偏好，而是基於義理完整性、工夫次第性、救弊針對性、成聖適配性四大核心理論考量，是對先秦儒學的重構與理學化的體系完善，可從四大維度深度闡釋。

Surveying the entire Cheng–Zhu Neo-Confucian system, their honoring of The Great Learning and establishing it as the correct path for entering virtue in the Confucian school was not a matter of canonical preference, but was based on four core theoretical considerations: doctrinal completeness, sequentiality of practice, targeted correction of contemporary ills, and suitability for achieving sagehood. This represented a reconstruction of pre-Qin Confucianism and a Neo-Confucian systemic perfection, which can be deeply elucidated from four major dimensions.

（一）義理體系完備：唯一貫通“心性涵養”與“窮理進學”的經典，破解入德工夫二元割裂

(A) Complete Doctrinal System: The Only Classic That Integrates "Nourishment of Mind-and-Nature" and "Exhaustive Investigation of Principle to Advance Learning," Resolving the Dichotomy in the Practice of Entering Virtue

朱熹明確提出，入德的核心在於“主敬致知，交相為助”，涵養居敬（未發靜功）與窮理致知（已發動功）如車之兩輪、鳥之兩翼，不可偏廢。單主敬而不窮理，則易墮入佛老空寂，空心守性、無義理支撐；單窮理而不主敬，則易滯於形器字句，逐末忘本、無德性主宰，二者偏廢皆為修德大病。而遍覽儒家經典，唯有《大學》完美融合了程朱“敬以直內、義以方外”的核心工夫，實現了涵養與致知的辯證統一。

Zhu Xi clearly pointed out that the core of entering virtue lies in "abiding in reverence and extending knowledge, with the two aiding each other." Nourishing the self and abiding in reverence (the still practice of the unaroused state) and exhaustively investigating principle to extend knowledge (the active practice of the aroused state) are like the two wheels of a cart or the two wings of a bird – neither can be dispensed with. If one exclusively abides in reverence without investigating principle, one easily falls into the empty stillness of Buddhism and Daoism, guarding the nature with an empty mind and without doctrinal support. If one exclusively investigates principle without abiding in reverence, one easily stagnates among concrete implements and phrases, pursuing the branches and forgetting the root, without a moral master. Neglecting either is a grave illness in moral cultivation. A comprehensive survey of the Confucian classics reveals that only The Great Learning perfectly integrates the core practice of the Cheng–Zhu school, "rectifying the inner with reverence and regulating the outer with righteousness," achieving a dialectical unity of self-nourishment and the extension of knowledge.

《大學》以“八條目”構建了完整的修德體系：格物、致知對應“進學致知”的向外窮理之功，要求學人探究萬事萬物之天理，破除愚昧偏執，解決“擿埴冥行”、學無門徑的困境；誠意、正心對應“涵養主敬”的向內存心之功，要求學人收拾身心、專一主宰、去除私慾，實現未發涵養、已發省察的動靜合一。朱熹在《朱子語類》中反覆強調：“存養中便有窮理工夫，窮理中便有存養工夫”，而《大學》的核心價值，正是將二者固化為不可分割的成聖工夫，徹底解決了當時學界“重內輕外、重靜輕動、重涵養輕窮理”的片面學風。

The Great Learning constructs a complete system of moral cultivation through the "Eight Items": investigating things and extending knowledge correspond to the outward practice of "advancing learning and extending knowledge," requiring learners to probe the Heavenly Principle in all things, break through ignorance and obstinacy, and resolve the dilemma of "groping blindly in the dark" and learning without a gateway. Making the will sincere and rectifying the mind correspond to the inward practice of "nourishing the self and abiding in reverence," requiring learners to gather body and mind, concentrate on a single master, eliminate selfish desires, and realize the unity of stillness and activity in nourishing before arousal and examining after arousal. In Classified Conversations of Zhu Xi, Zhu Xi repeatedly emphasized: "Within preserving and nourishing, there is already the practice of investigating principle; within investigating principle, there is already the practice of preserving and nourishing." The core value of The Great Learning is precisely to solidify these two as an inseparable practice of sagehood, thoroughly resolving the one-sided scholarly tendencies of that time, which "valued the inner and slighted the outer, valued stillness and slighted activity, and valued self-nourishment and slighted the investigation of principle."

相較於《論語》語錄零散、《孟子》側重心性義理、《中庸》偏重天道境界，《大學》不空談天理、不玄論心性，而是將抽象的“入德”轉化為可操作、可兼顧、不偏廢的敬知雙修體系，這是二程、朱熹將其定為入德之門的首要義理依據。二程直言“入德之門，無如《大學》”，正是因其完美契合聖門“內外交修、知行合一”的修德本質。

Compared with the scattered sayings of the Analects, the Mencius' emphasis on mind-and-nature doctrine, and the Doctrine of the Mean's stress on the realm of Heavenly Dao, The Great Learning does not idly talk about Heavenly Principle or mysteriously discuss mind-and-nature, but transforms the abstract "entering virtue" into a practicable, balanced, and non-partial dual cultivation system of reverence and knowledge. This is the primary doctrinal basis for the Cheng brothers and Zhu Xi to establish it as the Gateway to the Virtue Realm of Sagehood . The Cheng brothers directly stated, "For the Gateway to the Virtue Realm of Sagehood , nothing compares to The Great Learning," precisely because it perfectly matches the essence of moral cultivation in the Confucian school: "inner and outer cultivation combined, knowledge and action united."

（二）工夫次第嚴謹：構建循序漸進的成聖階梯，適配學人從凡入聖的修養規律

(B) Rigorous Sequence of Practice: Constructing a Gradual Ladder to Sagehood That Fits the Law of Self-Cultivation from the Ordinary to the Sage

“學為聖賢”並非一蹴而就的頓悟，而是日積月累、層層遞進的踐履過程，這是程朱德性修養的核心認知。朱熹強調進德修業需“日新又新、乾乾不息”，反對空談聖賢氣象、妄想一蹴而成聖。而《大學》區別於其他經典的核心優勢，在於其擁有獨一無二、環環相扣、次第森嚴的修德次第，為學人提供了從入門到大成的完整成聖路徑。

"Learning to become a sage" is not a sudden enlightenment achieved in one leap, but a gradual, accumulating, and step-by-step practice process; this is a core understanding of Cheng–Zhu moral cultivation. Zhu Xi emphasized that advancing in virtue and cultivating one's vocation requires "daily renewal and unceasing vigor," opposing empty talk of the sage's aura and the delusion of attaining sagehood in a single bound. The core advantage of The Great Learning that distinguishes it from other classics is that it possesses a unique, interlocking, and rigorously ordered sequence of moral cultivation, offering learners a complete path to sagehood from entry to full accomplishment.

《大學》三綱領、八條目構建了完整的成聖進階鏈條：始於格物致知，破除認知蒙蔽，明辨天理人慾；進而誠意正心，凈化心性本體，樹立道德主宰；根基在於修身，實現個體德性圓滿；向外推及齊家、治國、平天下，完成德性的社會化、宇宙化開顯。這一次第完全契合朱熹“修德是本，講學為用”的核心原則：格致講學是進學之方，誠正修身是修德之本，本末有序、輕重有別，完美回應了孔子“德之不修，學之不講”的教化之憂。

The Three Guiding Principles and Eight Items of The Great Learning construct a complete progressive chain for sagehood: it begins with investigating things and extending knowledge to break through cognitive delusions and clearly distinguish Heavenly Principle from human desires; then proceeds to making the will sincere and rectifying the mind to purify the original substance of mind-and-nature and establish a moral master; its root lies in self-cultivation, achieving personal moral completeness; and it extends outward to regulating the family, governing the state, and bringing peace to the world, completing the socialization and cosmic manifestation of virtue. This sequence perfectly matches Zhu Xi's core principle that "cultivating virtue is the root, while lecturing and learning is the function": investigating things, extending knowledge, and lecturing are the methods for advancing learning, while making the will sincere, rectifying the mind, and self-cultivation are the root of cultivating virtue. Root and branch are ordered, and weight and priority are distinguished, perfectly answering the educational concern of Confucius that "virtue is not cultivated, and learning is not expounded."

二程指出，當世學者迷失入德之門，核心癥結在於無次第、無階梯，要麼好高騖遠、空談平治天下，要麼拘於小節、局限日用細碎。而《大學》的次第體系，實現了“自卑升高、由近及遠、由淺入深”的修養邏輯。從小學的灑掃應對、收心養性，到大學的窮理正心、修己治人，《大學》貫通人生全部修養階段，讓初學之士有入門之徑，精進之人有深造之方，杜絕躐等冒進、虛空求索的修德弊病。朱熹高度肯定這一特質，認為《大學》是學者立身進步之要，唯有依此次第用功，方能“知益明，守益固，舊習日改月化”。

The Cheng brothers pointed out that the key reason why scholars of that time lost the Gateway to the Virtue Realm of Sagehood was the lack of sequence and steps: they either aimed too high and far, emptily discussing how to pacify the world, or confined themselves to trivial details and daily minutiae. The sequential system of The Great Learning realizes the cultivation logic of "rising from the lowly to the elevated, advancing from the near to the distant, and proceeding from the shallow to the deep." From the elementary learning of sprinkling and sweeping, responding to others, gathering the mind and nourishing the nature, to the great learning of exhaustively investigating principle, rectifying the mind, cultivating oneself and governing others, The Great Learning threads through all stages of a person's cultivation, giving beginning scholars a way to enter and advanced practitioners a method for profound study, eliminating the moral cultivation defects of overleaping and rushing ahead or hollowly seeking in emptiness. Zhu Xi highly affirmed this characteristic, believing that The Great Learning is the essential key for a scholar to establish himself and make progress; only by applying effort according to this sequence can one "have increasingly clear knowledge, increasingly firm hold, and old habits transformed day by day and month by month."

（三）救弊功能鮮明：扭轉宋世學弊，重塑儒學務實入世的德性品格

(C) Distinctive Function of Remedying Maladies: Reversing the Scholarly Ills of the Song Era and Reshaping the Practical, World-Engaging Moral Character of Confucianism

二程、朱熹推崇《大學》，具有極強的時代針對性，核心是為了挽救宋代儒學衰敗、異論蜂起的學術危局。朱熹明確批判當世學風兩大弊端：“語高則偏於空寂，卑則滯於形器”。一方面，佛老學說盛行，學者沉溺虛空頓悟，捨棄人倫日用、修身治世的實功，背離儒家入世之本；另一方面，俗儒只讀經書字句、追逐功利，以讀書窮理為技藝，不以修德成聖為目標，本末倒置、德性荒蕪。

The Cheng brothers and Zhu Xi's veneration of The Great Learning had a strong contemporary relevance, its core aim being to rescue the perilous scholarly situation of Song Confucianism, which was declining and rife with heterodox views. Zhu Xi explicitly criticized two major maladies of the scholarly ethos of his time: "Those who speak loftily incline toward emptiness and quietism; those who speak humbly stagnate among concrete forms and implements." On one hand, Buddhist and Daoist doctrines were prevalent, and scholars indulged in the empty and tranquil sudden awakening, abandoning the practical work of human relations, daily affairs, self-cultivation, and ordering the world, and thus deviating from the foundation of Confucian world engagement. On the other hand, vulgar Confucians merely read the words and phrases of the classics, pursuing utility and gain, treating reading and investigating principle as a technical skill without aiming at moral cultivation and sagehood, putting the cart before the horse and leaving virtue barren.

在朱熹看來，諸多經典或義理高深、初學難入，或偏重紀事、義理零散，無法救治當世學弊。唯獨《大學》不偏空、不滯器，居於“正當緊要親切合理之處”：既講求窮理致知，杜絕空疏虛妄；又堅守誠意修身，破除功利形器之蔽；既重心性涵養的內聖之功，又重經世致用的外王之業，完美對沖了當時儒學的兩大偏執。

In Zhu Xi's view, many classics were either too profound in doctrine for beginners to enter, or biased toward recording events with scattered principles, and thus could not remedy the scholarly ills of the age. Only The Great Learning, neither inclining toward emptiness nor stagnating in concrete forms, stands at "the precisely crucial, intimate, and reasonable point": it both stresses the investigation of principle and extension of knowledge, eradicating emptiness and falsehood, and firmly holds to making the will sincere and self-cultivation, breaking through the obscuration of utility and concrete forms; it attends to the inner sagely work of nourishing mind-and-nature and also to the outer kingly enterprise of ordering the world and putting learning into practice, perfectly counterbalancing the two major biases of contemporary Confucianism.

同時，針對當時“假佛釋之似以亂孔孟之實”“以讀書窮理為大禁”的異端亂象，二程明確斷言：“《大學》，孔子遺言也。學者由是而學，則不迷於入德之門也。”在理學看來，《大學》是孔孟聖學的正統真傳，是區別於佛老異端、俗儒末學的核心標尺。以《大學》為入德之門，便是確立聖學正統，為天下學人劃定修德正軌，杜絕異說惑亂、邪妄滋長，這是程朱擇定《大學》的重要時代與學術使命。

At the same time, aimed at the heterodox chaos of "using the semblance of Buddhism to confuse the reality of Confucius and Mencius" and "making reading and investigating principle a great prohibition," the Cheng brothers clearly declared: "The Great Learning is the transmitted word left by Confucius. If a scholar learns by following it, he will not lose his way at the Gateway to the Virtue Realm of Sagehood." From the Neo-Confucian viewpoint, The Great Learning is the orthodox, genuine transmission of Confucius and Mencius' sagely learning, the core standard for distinguishing heterodox Buddhism and Daoism and the inferior learning of vulgar Confucians. To take The Great Learning as the Gateway to the Virtue Realm of Sagehood  is to establish the orthodoxy of the sagely learning, delimit the correct path of moral cultivation for all scholars under Heaven, and put an end to the confusion of heterodox doctrines and the growth of deviant falsehoods. This was an important contemporary and academic mission of the Cheng–Zhu school in choosing The Great Learning.

（四）成聖格局完整：貫通內聖外王，實現個體德性與天下治理的終極統一

(D) Complete Scope of Sagehood: Integrating Inner Sage and Outer King, Realizing the Ultimate Unity of Individual Virtue and World Governance

程朱理學的終極目標，並非獨善其身的個體修身，而是內聖外王、德濟天下的聖賢境界，其修德體系始終立足“學為聖賢、兼濟天下”的核心錨點。聖賢氣象絕非孤高隱逸、空守心性，而是剛健有為、日新不息、貫通身心、家國、天下的完整人格。而《大學》是先秦儒學中唯一將“個體心性修養”與“家國天下治理”完全貫通的經典，完美承載了程朱的聖賢理想。

The ultimate goal of Cheng–Zhu Neo-Confucianism is not individual self-cultivation for one's own perfection alone, but the sage's realm of inner sage and outer king, benefiting the world with virtue. Its moral cultivation system is always grounded in the core anchor of "learning to become a sage and simultaneously benefiting the world." The aura of the sage is by no means one of aloof seclusion and empty guarding of the mind-and-nature, but rather a complete personality that is vigorous and active, daily renewing without cease, and connects body and mind, family and state, and the entire world. The Great Learning is the only classic of pre-Qin Confucianism that completely connects "individual cultivation of mind-and-nature" with "governing family, state, and world," perfectly bearing the Cheng–Zhu ideal of sagehood.

從修養次第來看，《大學》實現了從身心之修到天下之治的層層開顯：格致誠正、修身是內聖工夫，成就個體純粹德性、復歸天理本性；齊家治國平天下是外王功業，將個體德性推擴於人倫、社會、家國乃至天下。這與朱熹“進德修業，不但為一身，亦欲有為於天下”的人生理想高度契合。朱熹強調，進德是心上日新，修業是事上篤行，聖賢之學必須身心並重、內外交修，既有涵養本心之靜，又有經世履職之動。

From the perspective of the cultivation sequence, The Great Learning realizes a step-by-step unfolding from the cultivation of body and mind to the governance of the world: investigating things, extending knowledge, making the will sincere, rectifying the mind, and self-cultivation constitute the inner sagely practice, achieving the pure virtue of the individual and returning to the original nature of Heavenly Principle; regulating the family, governing the state, and bringing peace to the world constitute the outer kingly enterprise, extending individual virtue into human relations, society, state, and the world. This highly matches Zhu Xi's life ideal that "advancing in virtue and cultivating one's vocation is not only for one's own person, but also desires to accomplish something for the world." Zhu Xi stressed that advancing in virtue is daily renewal in the mind, and cultivating one's vocation is earnest practice in affairs; the learning of the sage must equally stress body and mind, cultivate both inner and outer, possessing both the stillness of nourishing the original mind and the activity of ordering the world and fulfilling duties.

反觀其他經典，《中庸》極高明而道中庸，偏重天道性命的本體闡釋，缺乏具體的治世踐履次第；《論》《孟》多散見修身、為政之言，未成系統層級。唯有《大學》將個人德性修養與家國治理、天下平治融為一體，讓入德之學不再是孤立的個人心性修鍊，而是貫通自我、人倫、社會、天下的聖賢大業。即便延伸至當代全球治理視域，《大學》“修身—濟世”的邏輯依然成立，以個體德性之正，推及社群、國家、天下之治，正是儒家聖賢之道的終極格局。

In contrast, other classics like the Doctrine of the Mean, which is supremely brilliant yet practices the mean, lean toward ontological exposition of Heavenly Dao and human nature, lacking concrete sequential practice for ordering the world; the Analects and the Mencius contain mostly scattered sayings on self-cultivation and governance that do not form a systematic hierarchy. Only The Great Learning fuses individual moral cultivation with the governance of family, state, and the pacification of the world, making the learning of entering virtue no longer an isolated individual cultivation of mind-and-nature, but the great enterprise of sagehood that connects self, human relations, society, and the world. Even extending into the contemporary perspective of global governance, the logic of The Great Learning—"self-cultivation to benefiting the world"—still holds: beginning from the correctness of individual virtue and extending to the governance of community, state, and world is precisely the ultimate scope of the Confucian Way of the sage.

三、《大學》作為“入德之門”的核心價值與理學奠基意義

III. The Core Value of The Great Learning as the "Gateway to the Virtue Realm of Sagehood " and Its Foundational Significance for Neo-Confucianism

基於二程、朱熹的系統闡釋，《大學》超越了普通儒家經典的文本價值，成為宋明理學成聖之學的總綱領、德性修養的總範式、儒學復興的總抓手，其核心重要性可總結為三點。

Based on the systematic exposition of the Cheng brothers and Zhu Xi, The Great Learning transcends the textual value of an ordinary Confucian classic and becomes the general program for the learning of sagehood in Song–Ming Neo-Confucianism, the general paradigm for moral cultivation, and the general lever for the revival of Confucianism. Its core importance can be summarized in three points.

（一）確立聖學入門正軌，終結修德無門的學術迷茫

(A) Establishing the Correct Entrance to Sagely Learning, Ending the Scholarly Confusion of Having No Gate to Moral Cultivation

在程朱之前，儒家修德缺乏統一、系統的工夫範式，學者或盲從佛老、或拘於訓詁、或空談義理，始終不得聖學要領。二程首倡《大學》為入德第一門徑，朱熹進一步完善其義理、細化其次第、固化其地位，將“格致、誠正、修身、治世”確立為唯一正統的入德路徑。自此，儒家“學為聖賢”不再是模糊的道德願景，而是有門可入、有路可走、有階可攀的實修體系，徹底終結了漢唐以來儒學修德碎片化、功利化、空疏化的困境。

Before the Cheng brothers and Zhu Xi, Confucian moral cultivation lacked a unified and systematic paradigm of practice. Scholars either blindly followed Buddhism and Daoism, confined themselves to textual exegesis, or idly discussed principles, without ever grasping the essentials of the sagely learning. The Cheng brothers first advocated The Great Learning as the foremost gateway for entering virtue, and Zhu Xi further perfected its doctrine, refined its sequence, and solidified its status, establishing "investigating things and extending knowledge, making the will sincere and rectifying the mind, self-cultivation, and ordering the world" as the sole orthodox path of entering virtue. Henceforth, the Confucian "learning to become a sage" was no longer a vague moral vision but a real cultivation system with a gate to enter, a road to walk, and steps to climb, thoroughly ending the fragmented, utilitarian, and hollow predicament of Confucian moral cultivation since the Han and Tang dynasties.

（二）統一敬知雙修工夫，構建理學核心德性修養體系

(B) Unifying the Dual Practice of Reverence and Knowledge, Constructing the Core Neo-Confucian System of Moral Cultivation

《大學》完整承載了程朱“涵養用敬、進學致知”的核心工夫，實現了未發涵養與已發省察、靜守本心與動窮物理、內聖修身與外王經世的完美統一。朱熹通過闡釋《大學》，明確了“敬為存心之要、知為進學之功”，二者交相為助、循環精進，讓德性修養既有心性本源的根基，又有義理認知的支撐，徹底規避了偏靜、偏動、偏內、偏外的修德弊病，構建了理學獨一無二、圓融完備的德性工夫論體系。

The Great Learning fully bears the core practice of the Cheng–Zhu school: "For self-cultivation use reverence; for advancing in learning extend knowledge," achieving a perfect unity of nourishing before arousal and examining after arousal, of quietly guarding the original mind and actively investigating the principles of things, and of inner sagely self-cultivation and outer kingly ordering of the world. By explicating The Great Learning, Zhu Xi made clear that "reverence is the essential for preserving the mind, and knowledge is the effort for advancing learning," with the two aiding each other and advancing in a cyclical refinement. This gave moral cultivation both a root in the original source of mind-and-nature and support from cognitive doctrine, thoroughly avoiding the moral cultivation defects of leaning exclusively toward stillness, activity, inner, or outer, and thereby constructing the uniquely complete and well-rounded Neo-Confucian system of moral practice theory.

（三）重塑儒家聖賢理想，奠定內聖外王的中華文化精神內核

(C) Reshaping the Confucian Ideal of the Sage and Establishing the Inner Sage and Outer King as the Spiritual Core of Chinese Culture

《大學》以次第化、體系化的方式，將儒家聖賢人格落地為終身踐履的人生範式：初學以此修身立品，精進以此進德修業，大成以此治國平天下。朱熹強調，聖賢氣象不是空想的境界，而是步步篤行的結果，學者摒棄虛空體悟、執着切己修身，依《大學》次第用功，即可自卑升高、漸入聖賢之域。這一闡釋重塑了儒學務實、剛健、入世的核心品格，讓儒家成聖之學紮根人倫日用、貫通古今世事，成為中國傳統道德教育、人格塑造、治國理政的核心理論根基。

The Great Learning actualizes the Confucian sage personality, in a sequential and systematic way, as a life paradigm of lifelong practice: beginners use it to cultivate themselves and establish character, advanced practitioners use it to advance in virtue and vocation, and those of great accomplishment use it to govern the state and bring peace to the world. Zhu Xi emphasized that the sage's aura is not an imaginary realm but the result of sincere step-by-step practice. When a scholar abandons empty experience, persistently engages in concrete self-cultivation, and applies effort according to the sequence of The Great Learning, he can rise from the lowly to the elevated and gradually enter the realm of the sage. This interpretation reshaped the core character of Confucianism as practical, vigorous, and engaged in the world, rooting the Confucian learning of sagehood in human relations and daily affairs and connecting it with affairs past and present, making it the core theoretical foundation of traditional Chinese moral education, character formation, and governance.

二程、朱熹擇定《大學》為“入德之門”，絕非經典文本的簡單推崇，而是基於理學成聖目標、工夫邏輯、時代救弊的根本性理論抉擇。相較於諸經，《大學》兼具義理之圓融、次第之嚴謹、工夫之完備、格局之宏大、救弊之切實五大特質，唯一完整承載了“涵養致知交相發、內聖外王相貫通、身心天下相統一”的理學核心訴求。

The Cheng brothers and Zhu Xi's choice of The Great Learning as the "Gateway to the Virtue Realm of Sagehood " was by no means a simple endorsement of a classical text, but a fundamental theoretical decision based on the Neo-Confucian goal of sagehood, the logic of practice, and the need to remedy the ills of the time. Compared with other classics, The Great Learning possesses five major qualities: doctrinal completeness and harmony, rigorous sequentiality, comprehensive practice, grand scope, and concrete efficacy in correcting maladies. It alone fully bears the core Neo-Confucian demand: "Self-nourishment and the extension of knowledge stimulate each other; inner sage and outer king are interconnected; body, mind, and world are united as one."

以《大學》為門徑，學人得以破除修德迷茫、規避學風偏執，從格物致知的認知起步，經由誠意正心的心性涵養、修身立德的自我完善，最終抵達齊家治國平天下的聖賢境界。這一體系不僅構建了宋明理學完整的德性倫理與道德教育體系，更確立了中華儒學“學以成聖、德以濟世”的永恆精神內核，成為歷代士人修德立身、經世致用的根本準繩。

Taking The Great Learning as the gateway, learners can break through the confusion about moral cultivation, avoid one-sided scholarly tendencies, start from the cognitive beginning of investigating things and extending knowledge, pass through the mind-and-nature nourishment of making the will sincere and rectifying the mind and the self-perfection of self-cultivation and establishing virtue, and finally reach the sage's realm of regulating the family, governing the state, and bringing peace to the world. This system not only constructs the complete virtue ethics and moral education system of Song–Ming Neo-Confucianism, but also establishes the eternal spiritual core of Chinese Confucianism: "Learning to become a sage, and using virtue to benefit the world." It became the fundamental standard for generations of scholar-officials to cultivate virtue, establish themselves, and put their learning into practical use.
