涵養德性：成聖之根基與修齊治平之內核

—— 基於二程、朱熹《大學》八條目式聖賢之道的義理闡釋

Cultivating Virtue: The Foundation of Sagehood and the Core of Self-Cultivation, Family Regulation, State Governance, and World Peace

— An Neo-Confucian Interpretation of the Sagehood Path in the Eight Step Model of The Great Learning by the Cheng Brothers and Zhu Xi

二程與朱熹將 "涵養德性" 視為成就聖賢之道的核心工夫。程頤立 "涵養須用敬，進學則在致知" 為學聖綱領，朱熹進而以 "居敬窮理" 貫通《大學》格物、致知、誠意、正心、修身、齊家、治國、平天下全部條目。以 "學為聖賢" 為標的，德性涵養並非孤立的內心靜坐，而是與窮理認知、經世實踐雙向交織的漸進過程：它是格物窮理的主體條件，是誠意正心的落實處，是修己內聖的根本指向，也是安人外王的本源依據。二程、朱熹通過對《大學》八條目的理學重構，將涵養德性錨定為變化氣質、下學上達、終至 "與理為一" 的底層工夫，並以 "絜矩之道" 將傳統 "平天下" 轉化為基於德性感化的公共治理法則。

The Cheng brothers (Cheng Hao, Cheng Yi程顥，程頤) and Zhu Xi, leading Neo Confucian thinkers of the Song dynasty, regarded cultivating virtue as the core spiritual praxis on the path to sagehood. Cheng Yi formulated the maxim "Cultivation requires reverence; learning lies in the extension of knowledge" as the guiding principle for pursuing sagehood. Zhu Xi further integrated the doctrine of "maintaining reverence and probing principle to the utmost" across the entire Eight Step framework of The Great Learning: the investigation of things, extension of knowledge, sincerity of the will, rectification of the mind, cultivation of the self, regulation of the family, governance of the state, and bringing of peace to the world. Oriented toward the ultimate goal of "learning to become a sage," virtue cultivation is neither isolated inner quiet sitting nor purely external behavioral restraint, but a progressive process in which rational cognition and sociopolitical practice mutually penetrate. It serves as the subjective precondition for investigating things and fathoming principle, the concrete foothold for sincerity of will and rectification of mind, the fundamental orientation of self-cultivation and "inner sagehood," and the ontological basis for pacifying others and "outer kingship." Through their Neo Confucian reconstruction of the Eight Steps, the Cheng brothers and Zhu Xi anchored virtue cultivation as the underlying spiritual practice for transforming one's physical endowment, ascending from mundane daily practice to profound spiritual realization, and ultimately attaining "unity with the Heavenly Principle." They also recast the traditional Confucian ideal of "bringing peace to the world" into a set of public governance norms rooted in moral edification, mediated by the Confucian reciprocity principle of "the way of the measuring square." This paper systematically expounds the internal logic of this ideological system, clarifying the substantive connotation, internal hierarchy, and practical path of virtue cultivation in the ChengZhu Neo Confucian doctrinal system.

 一、德性涵養的概念界定與學聖工夫框架

 1. Conceptual Definition of cultivating virtue and the Framework of cultivating virtue for Learning to Become a Sage

作為其聖賢理論的核心，二程與朱熹構建了完整的德性涵養邏輯框架，明確界定了核心概念，並確立了從道德認知到社會實踐的漸進過程。該框架以"學為聖賢"為終極目標，以《大學》八條目為基本實踐序列，以"敬"與"理"的統一為方法論核心。

As the core of their sagehood theory, the Cheng brothers and Zhu Xi constructed a complete logical framework for virtue cultivation, with a clear definition of core concepts and a gradual progression from moral cognition to social practice. This framework takes "learning to become a sage" as the ultimate goal, The Great Learning's Eight Steps as the basic practical sequence, and the unity of "reverence" and "principle" as the methodological core.

 1.1 二程、朱熹論"涵養德性"

 1.1 The Cheng Brothers' and Zhu Xi's Views on "Cultivating Virtue"

二程與朱熹以 "存天理、滅人慾" 界定涵養德性的實質：通過誠敬操持與日常熏習，護持並擴充人心中天賦的至善本性，矯正由氣稟偏私、物慾遮蔽而生的不良氣質。在其理論中，"德性" 即天理在人身上的體現。程頤明言 "性即理也"，天賦人性本善，具足仁義禮智；但此內核易被私心雜念、感官慾望遮蔽，無法自然外發為合天理的行為。"涵養" 便是以 "主敬" 為抓手，時刻收斂身心、專註於理，排除私慾干擾，使本然善性逐步呈現、累積，終至 "誠於中，形於外"。

The Cheng brothers and Zhu Xi defined the essence of cultivating virtue as "preserving the Heavenly Principle and suppressing human desires." Through sincere inner reverence and daily moral habituation, this practice aims to maintain and expand the innate perfect good nature in the human heart, rectifying the biased and degenerate temperament caused by the partiality of one's physical endowment and the obscuration of material desires. In their theoretical system, "virtue" is the concrete manifestation of the Heavenly Principle—the universal moral law governing the universe—in the individual. Cheng Yi explicitly proposed the thesis: "Human nature is principle" (Er Cheng Yishu二程遺書). Human nature is originally good, inherently endowed with the four virtues of benevolence, righteousness, propriety, and wisdom; however, this moral core is easily obscured by selfish thoughts and sensory desires, making it difficult to manifest naturally as conduct in line with the Heavenly Principle. "Cultivation" thus takes "maintaining reverence" as the fundamental starting point: one must constantly gather body and mind upon the Heavenly Principle, fend off the interference of selfish desires, and allow the innate good nature to gradually emerge and accumulate, ultimately realizing the state where "sincerity within is manifested without."

程頤將涵養的核心抓手定為 "敬"，提出"涵養須用敬，進學則在致知"。"敬"不是儀錶上的恭敬，而是 "主一之謂敬，無適之謂一"——心始終專註於天理，不向外攀援，不偏離正道。它是一種內在的警覺與操持：既非釋氏閉目靜坐、隔絕外物的 "空靜"，也非僵化拘謹的刻意剋制，而是在起心動念、應事接物中保持收斂與鄭重。內心持敬，偏邪雜念自然無隙可入，本有善性便得以存養擴充。

Cheng Yi regarded "reverence" as the core methodological lever for virtue cultivation, putting forward the famous slogan: "Cultivation requires reverence; learning lies in the extension of knowledge." "Reverence" does not refer to mere outward courteous demeanor, but to an inner spiritual state of "abiding in oneness without distraction." That is, the mind always adheres to the Heavenly Principle, neither clinging to external objects nor deviating from the correct moral path. It is a kind of inner vigilance and self-restraint: neither the "empty quietude" of Buddhism, which advocates closing the eyes in meditation to isolate oneself from the world, nor a rigid, formalistic self-suppression. Rather, it consists in maintaining focus and solemnity in every thought and in all daily affairs. Only by upholding reverence can selfish desires be deprived of any opening to invade the inner mind, and the innate good nature be naturally preserved and expanded.

朱熹在此基礎上將 "涵養" 與 "窮理" 合為進德的 "兩輪""兩翼"："居敬、窮理二事，互相發。能窮理，則居敬工夫日益進；能居敬，則窮理工夫日益密。"內心持敬，方能不被私慾蒙蔽，集中精神探究事理；窮理既明，對天理的認知愈清晰，敬的工夫也愈紮實。朱熹尤重"敬"的貫通性 —— 從格物致知到治國平天下，無論向內存養還是向外行事，無一處可離敬，所謂"敬字是徹頭徹尾工夫，自格物致知，至治國、平天下，皆不外此"。涵養德性由此不是某一階段的特定任務，而是貫穿八條目、自凡人至聖人全過程的主線。

Zhu Xi further developed this theory, organically uniting "cultivation" and "probing principle to the utmost" as the "two wheels" or "two wings" of moral advancement. He emphasized: "Maintaining reverence and probing principle to the utmost are mutually reinforcing. To exhaust principle, one needs reverence as a foundation; to preserve reverence, one needs the clarity of principle" (Daxue Zhangju大學章句). Inner reverence keeps selfish desires at bay, creating the subjective condition for the rational exploration of moral principles; conversely, a thorough understanding of moral principles consolidates the foundation of reverence, making inner cultivation more focused and persistent. Zhu Xi particularly stressed the pervasiveness of reverence: from the initial stage of investigating things and extending knowledge to the final stage of bringing peace to the world, neither inner spiritual cultivation nor external social action can depart from the practice of reverence. He noted: "Reverence is a thoroughgoing practice, permeating every stage from investigating things and extending knowledge to governing the state and bringing peace to the world." Virtue cultivation is thus not a task confined to a single stage, but a continuous thread running through the entire Eight Step process, connecting the mundane and the sacred, inner cultivation and external action.

 1.2 "學為聖賢"：涵養德性的目標定位

 1.2 "Learning to Become a Sage": The Teleological Orientation of Cultivating Virtue

二程打破 "聖人天生" 的舊見，斷言 "人皆可以至聖人，而君子之學必至於聖人而後已。不至於聖人而後已者，皆自棄也"（《二程遺書》卷二十五）。聖人不是遙不可及的神明，而是普通人通過持續道德修養可企及的最高人格；有志於為學者必以聖人為終極標的，不可半途而廢。

The Cheng brothers broke with the long held traditional view that "sages are born with superior endowments," asserting that "any person can become a sage, and the gentleman's learning must reach sagehood before it stops. To stop before reaching sagehood is to abandon oneself" (Er Cheng Yishu, juan 25《二程遺書》卷二十五). A sage is not an unapproachable divine being, but the highest moral personality that ordinary people can attain through sustained virtue cultivation. Aspiring learners must take sagehood as the ultimate pursuit, rather than settling for partial achievements.

聖人與凡人的本質分別，不在天賦高低，而在德性涵養是否臻於極致 —— 是否全然保全本然善性、徹底掃除私慾之私，使一言一行皆合天理。程頤在《顏子所好何學論》中徑稱 "學以至聖人之道也"，將成聖的路徑落實為長期的德性涵養。朱熹則以 "復其初" 說聖人之境：通過後天修養恢復天賦至善之本性，而涵養德性正是實現這一恢復的日常工夫。在二程、朱熹的系統中，"學為聖賢" 不是口號，而是涵養德性的具體指向：德性每進一步，便是向聖人境域靠近一步；聖人的最高境域，也必然是涵養德性達於極致的自然結果。

The essential difference between a sage and an ordinary person lies not in innate talent or endowment, but in whether virtue cultivation has reached its pinnacle—whether one has fully preserved the innate good nature, completely eliminated the bondage of selfish desires, and brought every word and deed into conformity with the Heavenly Principle. In his Essay on What Yan Hui Loved to Learn, Cheng Yi clearly defined the ideal of "learning to become a sage," taking sustained virtue cultivation as the only path to sagehood. Zhu Xi subsequently refined this teleological logic, proposing that sagehood consists in "returning to one's original nature" (Daxue Zhangju大學章句). Through postnatal virtue cultivation, one recovers the perfect good nature endowed by Heaven, and the process of this recovery is precisely the gradual advancement of virtue cultivation. For the Cheng brothers and Zhu Xi, "learning to become a sage" is not an empty slogan, but the concrete directional guide for all virtue cultivation: every improvement in virtue brings one closer to the realm of sagehood; the ultimate realm of sagehood is inevitably the natural outcome of virtue cultivation perfected to the highest degree.

 1.3 《大學》八條目：涵養德性的踐履次第

 1.3 The Eight Steps of The Great Learning: The Progressive Praxis of Cultivating Virtue

為使涵養德性從抽象的內心修養轉化為可執行、可驗證的進德路徑，二程與朱熹接續《大學》"格物、致知、誠意、正心、修身、齊家、治國、平天下" 八條目，視其為涵養德性由認知而存養、由存養而實踐、由實踐而推廣的完整流程。為學者須循此次第，由內而外、由小及大、由淺入深，一步步踏實做工夫，方能成就聖賢人格。

To transform abstract virtue cultivation into a set of operable, verifiable moral practices, the Cheng brothers and Zhu Xi took The Great Learning's Eight Steps as the standard progressive sequence. This framework—the investigation of things, extension of knowledge, sincerity of the will, rectification of the mind, cultivation of the self, regulation of the family, governance of the state, and bringing of peace to the world—constitutes a complete logical chain, advancing from external cognitive exploration to inner spiritual cultivation, then to family social practice and finally to public state governance, realizing the unity of knowledge and action, inner cultivation and external application.

朱熹在《大學章句》中將八條目分作兩截：格物、致知、誠意、正心屬 "明明德" 的內聖工夫，核心是通過涵養德性明了、恢複本有善性；修身是連接內聖與外王的樞紐；齊家、治國、平天下屬 "新民" 的外王工夫，核心是將自身已成之德性推廣於家族、國家與天下，以德性感化他人、治理社會。

Zhu Xi further divided the Eight Steps into two interconnected tiers in his Commentary on the Great Learning: the first four steps—investigation of things, extension of knowledge, sincerity of the will, and rectification of the mind—belong to the "inner sagehood" practice of "manifesting the luminous virtue," which focuses on eliminating the obscuration of selfish desires and awakening the innate good nature through inner cultivation; the last three steps—regulation of the family, governance of the state, and bringing of peace to the world—belong to the "outer kingship" practice of "renewing the people," which requires extending one's own virtue to others, influencing and edifying the public to achieve universal moral improvement. The fifth step, cultivation of the self, serves as the critical pivot connecting inner sagehood and outer kingship: the previous four steps lay an inner foundation for personal cultivation, while the subsequent three steps are its natural extension and external verification.

八條目雖有階段，卻非截然割裂。涵養德性便是串聯所有條目的主線：格物致知是其認知基礎，誠意正心是其內心落實，修身是其實踐轉化，齊家治國平天下是其外發延伸。聖賢之道由此從少數人憑天賦企及的高遠境界，轉為每個普通人都能通過漸進工夫一點一滴涵養德性、逐步實現的可及目標。

Although the Eight Steps are divided into stages, they are not mechanically isolated. Virtue cultivation acts as the core thread linking all of them: investigation of things and extension of knowledge provide the cognitive premise; sincerity of the will and rectification of the mind realize the internal landing; cultivation of the self completes the transformation of virtue from inner consciousness to external daily conduct; regulation of the family, governance of the state, and bringing of peace to the world extend virtue from the individual to the family, state, and ultimately the entire world. With this logical reconstruction, the Cheng brothers and Zhu Xi transformed the sagehood path from a transcendent ideal dependent on innate talent into an actionable, progressive practical system accessible to every ordinary person.

 二、格物致知：涵養德性的認知基礎與下手處

 2. Investigation of Things and Extension of Knowledge: The Cognitive Foundation and Starting Point of Cultivating Virtue

在程朱理學體系中，八條目始於格物致知，被視為德性涵養的認知基礎與下手處。道德修養必須建立在對道德原則的理性認知之上；沒有這種認知，德性涵養就會淪為盲目的、無目的的形式實踐。

In the Cheng Zhu Neo Confucian system, the Eight Steps begin with investigation of things and extension of knowledge, regarded as the cognitive foundation and starting point of virtue cultivation. Moral cultivation must be grounded in a rational cognition of moral principles; without such cognition, virtue cultivation becomes a blind, aimless formal practice.

 2.1 格物致知的理學本質

 2.1 The Moral Cognitive Essence of Investigation of Things and Extension of Knowledge

二程與朱熹對 "格物致知" 的解讀，與先儒註疏有本質差異，他們將這一認知方法升級為探究天理、認知善性的道德性認知實踐。程頤訓 "格" 為 "至"，"如祖考來格之格"，意為深入探究事物本質；又謂 "凡一物上有一理，須是窮致其理"天下萬事萬物皆有其存在的法則，格物即通過接觸、分析日常事物，窮究其背後天理之極致；致知則是令認知不斷推擴，終至明理之境。

The Cheng brothers' and Zhu Xi's interpretation of investigation of things and extension of knowledge marks a fundamental departure from the commentaries of earlier Confucian learners: they elevated this original cognitive method in The Great Learning into a moral cognitive practice aimed at exploring the Heavenly Principle and clarifying human moral nature. Cheng Yi redefined the meaning of "investigation": he interpreted ge (格) as "to arrive at," in the sense of "reaching the essence of things" (Er Cheng Yishu). He further emphasized: "Every single thing contains its own principle, and one must exhaustively explore its principle." For the Cheng brothers and Zhu Xi, "things" are not limited to natural objects, but more broadly cover human relations, daily affairs, and all social behaviors—the very reason investigation of things can connect with virtue cultivation. The so-called "principle" of things is ultimately the concrete manifestation of the universal moral law in specific human affairs.

二程、朱熹所謂 "物"，不限於自然事物，更廣泛涵蓋人倫日用與應事接物之理 —— 這正是格物能連通德性涵養的關鍵。程頤指出，窮理之途甚多：或讀書研討經典義理，或論古今人物辨別是非，或應事接物斟酌如何方為中正。朱熹補之以 "即物而窮其理"：不脫離具體事物憑空忖度天理，而在事中求理。此 "理" 歸根結底與人心本有的德性相通：窮事親之理，便是明如何盡孝；窮事君之理，便是明如何盡忠；窮交友之理，便是明如何守信。萬物之理，最終皆落腳於仁義禮智的道德實踐。

Cheng Yi believed there are many ways to explore principle: reading classical texts to delve into the meaning of the sages' ideas, evaluating the rights and wrongs of historical figures and events, or handling daily affairs to discern the most appropriate moral norms. Zhu Xi carried this view forward, proposing the famous doctrine of "investigating thing after thing to exhaust its principle" (Daxue Zhangju). He stressed that the exploration of principle cannot be separated from concrete affairs to engage in empty speculation; one must start from real life and explore the moral principle contained in each specific thing. The purpose of this cognitive practice is not to acquire instrumental natural knowledge, but to understand the universal moral principle rooted in human nature: by exploring the principle of serving one's parents, one clarifies the moral norm of filial piety; by exploring the principle of serving one's ruler, one clarifies the moral norm of loyalty; by exploring the principle of interacting with friends, one clarifies the moral norm of trustworthiness. The principles of all things are ultimately rooted in the innate good nature of the human heart, and the ultimate goal of investigating things and extending knowledge is to confirm and expand this innate good nature through the cognition of external things.

格物致知因而是涵養德性的必要前提。不先真切明白善道德理的內涵，所謂涵養便只是盲目的主觀死守，甚至誤入異端。唯有窮盡事物之理、認清道德本質，涵養中方能精準辨別天理與人慾，正確擴充善性。

Investigation of things and extension of knowledge are thus the necessary preconditions for virtue cultivation. Without first clarifying the substantive connotation of moral principles through rational cognition, virtue cultivation would be reduced to blind subjective attachment, or even deviate from the correct moral path and fall into heterodox practices.

 2.2 涵養須用敬：格物致知的前提條件

 2.2 Cultivation Requires Reverence: The Subjective Precondition for Investigation of Things

格物致知與涵養德性並非先後脫節，而是互相依存。格物致知是涵養德性的認知基礎，涵養德性則是格物致知能取得實效的前提 —— 無敬的涵養，格物致知易陷入心不在焉、認知偏差，無法達到窮理的真實目的。

Investigation of things and extension of knowledge, and virtue cultivation, are not in a linear, sequential relationship, but are interdependent and mutually reinforcing. Virtue cultivation is the subjective guarantee for the effectiveness of investigating things and extending knowledge: without the spiritual foundation of reverence, the cognitive process will be distracted by external material desires or biased subjective views, making a true understanding of moral principle impossible.

程頤 "涵養須用敬，進學則在致知" 一語，已將二者綁定。內心莊重收斂、專註集中，無浮躁渙散之雜念，探究事理時方能不被表象迷惑、不被私慾偏見干擾。反之，內心散漫放縱、無持敬基礎，格物時心思飄忽，或被外物牽引偏離正道，或被主觀成見蒙蔽真相，根本無從深入。

Cheng Yi's maxim—"Cultivation requires reverence; learning lies in the extension of knowledge"—precisely binds these two practices together. Only with an inner state of reverence—focused and concentrated, without impetuousness or distraction—can one avoid being confused by the surface of things and blinded by personal selfish biases in the process of investigating things and exploring principle. Without the spiritual foundation of reverence, even if one investigates things, one will be unable to concentrate, and may even be swayed by personal desires and subjective prejudices, making it impossible to truly exhaust the principle of things.

朱熹以 "持敬是窮理之本" 深化此義，將居敬與窮理比作兩腳、兩翼，不可偏廢。格物全程須持敬：接觸事物之初，以莊重專註態度探究本質；探究之中，收斂身心，不令雜念侵入認知；格物之後，又以敬鞏固所得，將外部認知逐步轉為內心道德自覺。格物非一蹴可就，須日積月累；而整個積累過程中，敬的工夫不可有絲毫鬆懈 —— 唯長期持敬，認知方能逐步深入，終至 "豁然貫通"。

Zhu Xi further deepened this logical connection, proposing that "maintaining reverence is the foundation of probing principle to the utmost" (Daxue Zhangju). He compared reverence and the exploration of principle to the two feet of a person or the two wings of a bird: both are indispensable and mutually promotive. The entire process of investigating things must be anchored in reverence: when first contacting a thing, one should explore its essence with a solemn and focused attitude; in the course of exploration, one should restrain body and mind to prevent distracting thoughts from invading cognition; after the exploration, one must consolidate the cognitive gains with reverence, transforming external moral knowledge into inner conscious moral conviction. Without the spiritual foundation of reverence, even if one investigates things, one will be unable to concentrate, and may even be swayed by personal desires and subjective prejudices, making it impossible to truly exhaust the principle of things.

 2.3 積累貫通：涵養德性的認知進階

 2.3 Accumulation and Penetration: The Cognitive Progression of Cultivating Virtue

通過格物致知涵養德性，非頓悟可成，而是由淺入深、由表及裡的漸進過程，與德性從認知到紮根、再到擴充的進階同步。

For the Cheng brothers and Zhu Xi, the process of investigating things and extending knowledge to cultivate virtue is not a transcendent moment of sudden enlightenment, but a gradual progression from the shallow to the deep, from the superficial to the profound—synchronized with the gradual growth of virtue from cognition to internalization.

程頤反對 "只格一物便通眾理" 的頓悟，指出 "人謂今日格一件，明日格一件，積習既多，然後脫然自有貫通處"。萬物之理散存於無數具體事物中，不可能由一事而盡曉天下之理；須長期持續探究，積累至一定程度，自然對天理形成整體貫通。所謂 "貫通"，並非此後不再格物，而是內心德性已被充分喚醒，能舉一反三、觸類旁通，將所窮之理與自身善性完整貫通。

Cheng Yi explicitly rejected the heterodox view that "investigating one single thing leads to simultaneous enlightenment of all principles," pointing out that "learners must investigate one thing today and another tomorrow. After accumulating practice over a long time, penetration will naturally come about" (Er Cheng Yishu). The principles of things are scattered in countless specific affairs, and it is impossible to comprehend all the principles of the world through a single act of investigation. Only through long term continuous accumulation and persistent exploration can one achieve an overall understanding of the Heavenly Principle. The so-called "penetration" does not mean the end of cognitive practice, but that the innate virtue in the heart has been fully awakened, enabling one to draw inferences from one instance and connect the cognitive gains from external things with the innate good nature of the heart.

朱熹承接此漸進積累說，進一步細化："物格者，物理之極處無不到也；知至者，吾心之所知無不盡也。" 格物就事物之理而言，須窮至極致無遺漏；致知就內心認知而言，須推至極致無模糊。長期積累一旦豁然貫通，便可實現 "眾物之表裡精粗無不到，而吾心之全體大用無不明"—— 既盡知萬物之理，又全然喚醒內心本有善性，使道德本體毫無遮蔽。

Zhu Xi took up this theory of gradual accumulation and further systematized it: "When investigating things, one must pursue the principle to the utmost; when extending knowledge, one must carry cognition to the utmost" (Daxue Zhangju). "Pursuing the principle to the utmost" means that the exploration of the principles of things must not stop at superficial phenomena, but must reach the core moral essence; "carrying cognition to the utmost" means that the cognition of moral principles must be expanded to the greatest extent without any ambiguity. He believed that after long term accumulation of cognitive practice, one will eventually achieve the state of "sudden penetration and comprehensive understanding": on the one hand, one has a thorough grasp of the external principles of all things; on the other, one's inner moral substance is completely illuminated, without any obscuration from selfish desires.

這一積累貫通的過程，本質上是德性涵養的一部分。格物之初，為學者所窮是事物表層的外部道理；涵養深入而至貫通，便知 "天理" 與 "人性" 本來貫通 —— 事物之理根源即在人心中本有之善性，格物的終極目的不是獲取外部知識，而是印證、擴充內心本有的善性。格物致知的積累，正是德性從認知到自覺的逐步涵養。

This process of accumulation and penetration is itself a concrete stage of virtue cultivation. At the beginning of investigation, the learner is still in the stage of understanding external factual principles; as cultivation deepens to the stage of penetration, he realizes that the Heavenly Principle and human nature are originally interconnected—the principle of external things is ultimately rooted in the innate good nature of the human heart. The ultimate goal of investigating things is not to acquire instrumental external knowledge, but to confirm and expand the innate good nature of the heart through the cognition of things.

 三、誠意正心：涵養德性的內在落實

 3. Sincerity of the Will and Rectification of the Mind: The Internal Implementation of Cultivating Virtue

格物致知既明天理，聖賢工夫便由對外認知轉向對內心性的存養 —— 此即誠意正心的任務。二程、朱熹視誠意正心為涵養德性的關鍵落地環節，也是連接 "格物致知" 與 "修身齊家" 的樞紐；無此一步，此前所得天理便無法轉為真實德性，只淪為空洞知識。

After investigating things and extending knowledge to achieve a rational cognition of the Heavenly Principle, the focus of sagehood practice shifts from external cognitive exploration to inner moral nurture. This is the task of the third and fourth steps of The Great Learning: sincerity of the will and rectification of the mind. These two steps are the key links for landing virtue cultivation in the inner world, connecting external moral cognition with inner moral consciousness. Without this internal transformation, the Heavenly Principle obtained by investigating things remains empty knowledge unrelated to the self, and cannot be converted into real moral virtue.

 3.1 誠意：涵養德性的真實落地

 3.1 Sincerity of the Will: The Genuine Implementation of Cultivating Virtue

誠意是銜接 "知" 與 "行" 的節點。朱熹《大學章句》定義誠意："誠其意者，毋自欺也，如惡惡臭，如好好色。" 意念真實無妄，不自欺欺人，如聞惡臭自然厭惡、見好色自然喜愛，無虛偽、無勉強。

Sincerity of the will is the key node connecting moral knowledge and moral practice. Zhu Xi defined this concept in his Commentary on the Great Learning: "Sincerity of the will means not deceiving oneself, just as one naturally hates a foul smell and naturally loves a beautiful countenance." It requires that inner moral intentions be true and without falsehood, neither deceiving others nor oneself; the love of good and hatred of evil must come from the heart, without any deliberate pretense.

程頤指出，誠意的實質是將格物致知所得天理實實在在落實於意念，做到表裡如一：知善便發自內心親近善、踐行善，知惡便發自內心厭惡惡、遠離惡，不可表面裝作好善惡惡，內心卻對私慾念念不忘。誠意的核心在 "實"—— 將外部道德認知轉為內心真實的道德自覺。做不到這一點，格物所得便只是與己無關的空疏學問，無法形成真正的德性。

Cheng Yi pointed out that the essence of sincerity of the will is to truly implement the Heavenly Principle obtained from investigating things and extending knowledge into inner moral intentions, achieving a complete unity of inner cognition and outer conduct (Er Cheng Yishu). If one knows that an act is good but does not genuinely want to practice it, or knows that an act is evil but does not genuinely want to avoid it—merely pretending to love good and hate evil on the surface—then one's will is insincere, and the moral principle obtained from investigating things remains empty, impractical knowledge. Sincerity of the will requires that the cognition of moral principles be transformed into genuine moral emotions and conscious intentions from the depths of the heart. This is the real landing of virtue cultivation.

做到誠意須依靠敬的涵養。二程謂 "敬是閑邪之道"——"閑" 即防範、制止，敬是防範偏邪私慾入侵內心的方法。人心易被私慾牽引，萌生虛偽不真之意念；唯時刻持敬，心專註於天理，方能從根源杜絕自欺的虛偽意念，自然生髮真實道德意念。朱熹補充說，格物致知之後，須以敬警省、把持自心，令好善惡惡的真實意念紮根於內，意念方能真誠，德性方能真正落地。

The key to achieving sincerity of the will lies in the cultivation of reverence. The Cheng brothers proposed that "reverence is the way to ward off evil" (Er Cheng Yishu). "Warding off evil" means preventing biased and selfish desires from invading the inner mind. The human heart is easily swayed by selfish desires, giving rise to false and dishonest thoughts; only by upholding reverence at all times and keeping the mind focused on the Heavenly Principle can one fundamentally cut off the possibility of self-deception. Zhu Xi added that after investigating things and extending knowledge, one must settle the mind with reverence, keeping it clear and focused. Only in this way can the moral principle obtained from investigation take root in the heart, the intention becomes sincere, and virtue be truly internalized.

 3.2 正心：涵養德性的心性平衡

 3.2 Rectification of the Mind: The Equilibrium of Moral Psychology

誠意是意念真誠，正心則是德性成熟所需的心性平衡狀態。《大學》謂 "身有所忿懥，則不得其正；有所恐懼，則不得其正；有所好樂，則不得其正；有所憂患，則不得其正"。朱熹注曰，忿懥、恐懼、好樂、憂患皆是人心自然產生的情緒，本身並非邪惡；但心若無敬的涵養基礎，放縱情緒隨意發作，令情緒遮蔽天理之主宰，心便失其平衡，德性也無從穩定存養。

Sincerity of the will ensures the authenticity of moral intentions, while rectification of the mind refers to the state of inner equilibrium required for virtue to mature into a stable character. As The Great Learning states: "When the mind is swayed by anger, it cannot be upright; when it is swayed by fear, it cannot be upright; when it is swayed by fondness, it cannot be upright; when it is swayed by anxiety, it cannot be upright." Zhu Xi commented that these four emotions—anger, fear, fondness, and anxiety—are natural emotional responses of the human heart and are not inherently evil. However, without the spiritual foundation of reverence to guide and regulate them, these emotions will be indulged and will obscure the mastery of the Heavenly Principle over the inner mind. The mind then loses its balanced and upright state, and virtue cannot be stably cultivated.

如何正心？二程的答案仍是主敬涵養。程頤說："敬只是主一也。主一，則既不之東，又不之西，如是則只是中。" 敬令心始終專註，不被外物牽引，不偏向任何一方，自然保持中正。平時以敬涵養身心，應事接物時心自然符合天理準則，不良情緒自然得以節制；若無敬的基礎，只靠強行壓制情緒，即便暫時有效，也無法長久保持平衡，更無從形成穩定德性。

The only way to achieve rectification of the mind is sustained cultivation through reverence. Cheng Yi said: "Reverence is simply abiding in oneness. Abiding in oneness means not leaning eastward or westward, thus dwelling in the mean" (Er Cheng Yishu). "Abiding in oneness" means that the mind is always focused on the Heavenly Principle, not swayed by external material desires, not biased by personal emotions, and thus naturally maintains an impartial and upright state. If one can uphold reverence in daily life, the mind will naturally conform to the Heavenly Principle when handling affairs, and excessive emotions will be naturally restrained. Without the foundation of reverence, even if one can suppress emotions by force temporarily, one cannot maintain inner balance for long, let alone form a stable moral character.

朱熹細化正心與涵養德性的關聯：心是身之主宰，德性是心之主宰；唯以敬涵養，令心時刻被德性主宰，不被情緒牽引、不被私慾遮蔽，方能始終中正。這種正心工夫非一蹴而就，須長期日常體察操持：未接物時收斂身心，警惕私慾萌生；接物時稱量輕重緩急，不令情緒左右判斷；無論動靜，時刻持敬，令天理始終主導內心。如此，德性方能持續存養，逐步形成穩定的道德定力，縱使遭遇外界干擾誘惑，也不輕易偏離天理。

Zhu Xi further refined the internal connection between rectification of the mind and virtue cultivation. He proposed: "The mind is the master of the body, and virtue is the master of the mind" (Daxue Zhangju). Only by cultivating the mind with reverence can virtue always dominate the inner mind, preventing it from being swayed by emotions or obscured by selfish desires. This practice cannot be achieved overnight; it requires long-term daily introspection and abiding by reverence. When not engaging with external affairs, one should restrain body and mind, be vigilant against the germination of selfish desires, and keep the mind focused on the Heavenly Principle; when engaging with external affairs, one should weigh the relative importance, distinguish right from wrong, and prevent personal emotions from clouding moral judgment. Whether in action or in tranquility, one must always uphold reverence, allowing the Heavenly Principle to guide the inner mind. Only then can virtue be continuously nurtured and gradually transformed into a stable moral conviction that will not be easily shaken by external temptations or interference.

 3.3 慎獨：涵養德性的日常操持

 3.3 Vigilance in Solitude: The Daily Discipline of Cultivating Virtue

誠意正心本質上是不依賴外人監督的自覺內在修鍊，二程、朱熹以《大學》"慎獨" 為其具體操持方法。《大學》論誠意特標 "君子必慎其獨也"，朱熹註："君子必慎其獨者，蓋他人所不及知，而己獨知之也。" 在他人看不到、聽不到的獨處情境中，在只有自己知曉的隱秘念頭萌發時，仍保持敬畏，謹慎對待意念，嚴格依道德準則要求自己，不做任何自欺之事。

Sincerity of the will and rectification of the mind are essentially spontaneous inner practices that do not depend on external supervision. To ensure their continuity and authenticity, the Cheng brothers and Zhu Xi took The Great Learning's doctrine of "vigilance in solitude" (shendu慎獨) as the specific daily discipline for cultivating virtue. In its discussion of sincerity of the will, The Great Learning emphasizes: "The noble person must be cautious when alone." Zhu Xi annotated: "The reason the noble person must be cautious when alone is that others cannot know one's inner thoughts—only one's own self is aware of them" (Daxue Zhangju大學章句). Even in an unsupervised private situation where no one else is watching, when a private thought germinates known only to oneself, one must still maintain awe and vigilance toward the Heavenly Principle, carefully treat every inner intention, and strictly restrain one's own conduct.

慎獨是涵養德性的關鍵抓手，也是驗證涵養是否有效的標準。公開場合有監督，多數人能刻意表現出合道德的言行；獨處時無外界約束，許多人便放鬆要求，任由不善念頭萌發甚至付諸行動。而真正的德性恰在獨處細微處存養：獨處時能慎獨，在細微處警醒持敬、主動排除不善之念、令細微善念逐步擴充，德性便逐漸紮根內心；反之，獨處時不能慎獨，刻意做掩人耳目之事，此前格物致知工夫便等於落空，德性根本無從涵養。

Vigilance in solitude is a critical lever for cultivating virtue and an important criterion for verifying its effectiveness. In public social situations, constrained by external public opinion and moral supervision, most people can deliberately restrain their behavior and maintain moral compliance; in unsupervised private situations, however, many relax their moral vigilance, indulge selfish desires, and even do things that violate moral norms. Genuine virtue is precisely nurtured in these trivial, unsupervised private moments. If one can practice vigilance in solitude—remaining vigilant and upholding reverence in private, proactively eliminating unwholesome thoughts and expanding nascent good intentions—virtue will gradually take root in the heart. Conversely, if one cannot practice vigilance in solitude, acting deceptively to conceal one's misdeeds from others, all previous efforts in investigating things and extending knowledge will be in vain, and true virtue cannot be cultivated at all.

慎獨是 "主敬" 工夫的深化：敬貫穿一切時，慎獨便是敬在無外界監督的獨處場景下的具體體現。二程謂 "閑邪則誠自存"—— 獨處時主動防範制止私慾產生，真誠存養善念，此即慎獨的核心，也是誠意正心最真實的落地狀態。

Vigilance in solitude is also a deepening of the practice of reverence. Reverence pervades all moments of daily life, and vigilance in solitude is its concrete manifestation in unsupervised private situations. The Cheng brothers said: "Evil is warded off, and sincerity will naturally be preserved" (Er Cheng Yishu二程遺書). In private situations, if one can actively guard against the germination of selfish desires and consciously keep the mind focused on moral principles, then sincerity of the will and rectification of the mind can be truly implemented.

 四、修身：涵養德性的實踐樞紐

 4. Cultivation of the Self: The Pivotal Link in the Practice of Cultivating Virtue

八條目之中，修身是核心樞紐。二程、朱熹認為，修身是涵養德性的直接實踐指向，是連接內聖工夫與外王事業的橋樑；格物致知、誠意正心是修身的內在基礎，齊家、治國、平天下是修身的自然延伸與外在驗證。不能在修身環節落地實踐，內在涵養再深厚，也無從成就外王事業。

In the Eight Step framework, cultivation of the self serves as the core pivot connecting inner sagehood and outer kingship. The previous four steps—investigation of things, extension of knowledge, sincerity of the will, and rectification of the mind—lay an inner moral foundation for self-cultivation; the subsequent three steps—regulation of the family, governance of the state, and bringing of peace to the world—are its natural extension and external verification. Without the practical transformation of self-cultivation, all inner virtue cultivation remains empty spiritual talk and cannot be converted into the ability to govern others and conduct social affairs.

 4.1 修身的本質：涵養德性，轉化氣質

 4.1 The Essence of Self-Cultivation: Nurturing Virtue and Transforming Physical Endowment

二程、朱熹所謂 "修身"，非簡單的行為規範，而是內在德性的持續涵養與氣質的徹底轉化。程頤提出 "學至氣質變，方是有功"（《二程遺書》卷十八）：為學修養的真正功效，不在知識增長或表面行為合規，而在轉化生而帶有的偏狹氣質，使之與天理相合。凡人之所以偏離道德，根源在於氣質有偏頗、易被私慾牽引；修身的本質即以德性涵養工夫不斷矯正轉化這種偏狹氣質，令本有善性全然呈現。

For the Cheng brothers and Zhu Xi, cultivation of the self is not mere external behavioral regulation, but the continuous nurture of inner virtue and thorough transformation of one's physical endowment. Cheng Yi proposed: "Learnership is only meritorious when it transforms one's physical endowment" (Er Cheng Yishu, juan 18《二程遺書》卷十八). "Physical endowment" refers to the innate spiritual and emotional predisposition of a person, which is inherently neither good nor evil; if not guided by virtue and obscured by selfish desires, however, it leads to biased and immoral behavior. The real effect of self-cultivation lies not in the growth of knowledge or the compliance of superficial behavior, but in continuously rectifying this biased physical endowment through virtue cultivation, bringing it into conformity with the Heavenly Principle, and fully manifesting the innate good nature.

朱熹承接此義，將修身釋為 "去其私慾之蔽，而復其本然之善"。人天賦本性純粹至善，但生而具有的氣質有清濁偏正之異；這本無善惡，然後天應事接物中，氣質受外物牽引、私慾遮蔽，本有善性便無法自然流露，甚至表現為惡的言行。修身的核心即以敬的涵養工夫，一方面克除私慾對善性的遮蔽，逐步減少乃至徹底消除人慾影響；另一方面主動存養擴充本有善性，令善性逐步主導言行，終至氣質徹底轉化。

Zhu Xi took up this view and systematically expounded the logical relationship between virtue cultivation and physical endowment transformation. He believed that human nature is originally pure and good, but the physical endowment one is born with varies in clarity, turbidity, partiality, and uprightness. In postnatal life, if the physical endowment is influenced by external material desires and not guided by virtue cultivation, it will gradually obscure the innate good nature, leading to immoral behavior. The essence of self-cultivation is therefore to "dispel the obscuration of selfish desires and restore one's innate goodness" (Daxue Zhangju). On the one hand, it is necessary to overcome the bondage of selfish desires to the physical endowment and gradually reduce their influence; on the other, one must actively nurture and expand the innate good nature, making virtue the dominant force in daily behavior. The ultimate goal is a complete transformation of the physical endowment, so that every word and deed naturally conforms to the Heavenly Principle.

修身不是單純的外在行為矯正，而是以德性涵養為核心的內外整體修鍊。二程謂 "有諸中者，必形諸外"—— 內在有德，外在言行自然流露。朱熹注 "修身"引程頤 "敬以直內，義以方外"：以敬涵養令內心正直，以道義令行為合規矩。修身的實質，是通過涵養德性實現內心與外在行為的同步端正，使言行自然合於道德準則。

The Cheng brothers stressed that self-cultivation is not a one-sided rectification of external behavior, but a holistic inner-outer transformation centered on virtue cultivation. They said: "What is within will surely be manifested without" (Er Cheng Yishu二程遺書). If one's inner virtue is cultivated to a sufficient extent, it will naturally manifest in external behavior, without the need for deliberate external restraint. Zhu Xi quoted Cheng Yi's famous thesis in his commentary: "Reverence is used to rectify the inner self, and righteousness is used to square the outer self." Inner reverence cultivation straightens the mind, bringing it into conformity with the Heavenly Principle; the discipline of righteousness regulates external behavior, bringing it into conformity with moral norms. The essence of self-cultivation is to achieve simultaneous rectification of the inner mind and external conduct through the unity of reverence and righteousness.

 4.2 克己復禮：涵養德性的實踐方法

 4.2 Restraining the Self and Returning to Propriety: The Practical Method of Cultivating Virtue

修身實踐中，二程、朱熹繼承孔子 "克己復禮"，以其為涵養德性的核心實踐方法，也是將內在德性轉為外在言行的關鍵路徑。"克己" 即剋制自身私慾雜念，"復禮" 即令言行合於天理的道德準則。二程謂 "敬勝百邪"（《近思錄》卷四），內心誠敬，自然可克服各種私慾干擾；克己的過程本質上也就是涵養德性的過程 —— 私慾與善德對立，私慾減一分，善德便擴充一分，克私愈徹底，涵養愈深厚。

In the specific practice of self-cultivation, the Cheng brothers and Zhu Xi inherited Confucius' doctrine of "restraining the self and returning to propriety" (keji fuli克己復禮), regarding it as the core practical method for cultivating virtue and the critical path for transforming inner virtue into external daily conduct. "Restraining the self" means curbing one's selfish desires and deviant thoughts; "returning to propriety" means ensuring that one's words and deeds conform to the moral principles embodied in the Heavenly Principle. The Cheng brothers believed that the core of this practice is the cultivation of reverence: "Reverence overcomes all evils" (Jinsilu, juan 4《近思錄》卷四). If one can maintain a state of reverence in daily life, focusing on the Heavenly Principle, one can naturally overcome the interference of various selfish desires. The process of restraining the self is essentially the process of cultivating virtue: as selfish desires diminish by one degree, good virtue expands by one degree; the more thoroughly selfish desires are curbed, the deeper one's virtue cultivation becomes.

朱熹細化這一實踐過程：克己復禮須在日常應事接物的小事上實實在在踐行，不可有一刻鬆懈。衣食住行、待人接物的每一個細節中，都要主動約束私慾，令言行完全符合禮的規範 —— 此 "禮" 非外在僵化制度，而是天理在社會生活中的具體體現。要做到 "非禮勿視，非禮勿聽，非禮勿言，非禮勿動"：在每一個具體言行上把持住敬的狀態，令道德準則貫穿行為細節。

Zhu Xi further detailed the specific practical path.He stressed that this practice cannot be limited to major events or formal occasions, but must be implemented in every trivial detail of daily life: in the basic necessities of life, in the process of interacting with others, and in the handling of all manner of daily affairs, one must consciously restrain selfish desires and regulate behavior according to the requirements of propriety. The "propriety" referred to here is not rigid external institutional norms, but the concrete manifestation of the universal moral principle in social life. The core of returning to propriety is to make one's behavior conform to the moral norm of the Heavenly Principle. This practice requires adhering to the Confucian precepts: "Do not look at what is contrary to propriety, do not listen to what is contrary to propriety, do not speak what is contrary to propriety, and do not make a move that is contrary to propriety."

這種踐行本質上是對德性涵養的持續強化。日復一日、時時刻刻的約束與訓練，外部道德規範逐步轉為內心道德自覺，一時的自覺逐步轉為穩定的道德習慣；最終無需刻意剋制、無需外在監督，言行自然完全合於天理，德性臻於成熟。這正是《大學》"身修而後家齊" 的內在邏輯：唯有完成自身德性涵養，方能進一步教化家人、治理社會。

This daily restraint and training is essentially a continuous reinforcement of virtue cultivation. Through long term unremitting practice, external moral norms are gradually transformed into inner conscious moral conviction, and temporary moral consciousness is consolidated into a stable moral character. Eventually, one is able to act in accordance with moral norms without deliberate restraint or external supervision. This is the internal logic of The Great Learning's dictum that "the self being cultivated precedes the regulation of the family": only by completing the cultivation of one's own virtue can one further edify family members and govern society.

 4.3 修身為本：涵養德性的價值邏輯

 4.3 Self-Cultivation as the Foundation: The Value Logic of Cultivating Virtue

《大學》謂 "自天子以至於庶人，壹是皆以修身為本"。二程、朱熹視此為聖賢之道的核心價值邏輯：無論天子還是庶民，無論何種事業地位，皆須以修身為根本前提；而修身的本質又是涵養德性 —— 這意味着涵養德性是所有事業的底層基礎，也是成聖成賢的根本落腳點。

As The Great Learning states: "From the son of heaven down to the common people, all must take self-cultivation as the foundation." The Cheng brothers and Zhu Xi regarded this thesis as the core value logic of the entire sagehood system: regardless of sovereign or commoner, regardless of one's career or status, all must take self-cultivation as the fundamental prerequisite for all external social endeavors; and the essence of self-cultivation is precisely virtue cultivation. Cultivating virtue is thus the underlying foundation of all human endeavors and the fundamental foothold for achieving sagehood.

二程以 "本末" 邏輯說明修身的核心地位：德性是根本，外在事業是末梢；先立根本，涵養完成自身德性，外王事業才有出發點。不先修身涵養德性而欲教化他人、治理國家，如同不結實之木欲求枝葉繁茂、無基礎之建築欲成高樓，斷無可能。程頤以種樹為喻："根本須是先培壅，然後可立趨向也"（《近思錄》卷二）——種樹須先夯實土壤、培好根本，樹木方能高大；為學者須先涵養自身德性，方能確立正確人生方向，後續齊家治國平天下才有堅實支撐。

The Cheng brothers explained the core status of self-cultivation through the logical relationship between "root" and "branch": virtue is the root, and external social endeavors are the branches; only by establishing the root first—by cultivating and completing one's own virtue—can the outer kingship enterprise have a solid starting point. To attempt to edify others or govern the state without first cultivating the self and nurturing virtue is like expecting a fruitless tree to flourish with leaves and branches, or building a high-rise without a foundation—an impossibility. Cheng Yi used the metaphor of planting a tree: "The root must first be banked up with soil, then the tree can grow toward the sky" (Jinsilu, juan 2《近思錄》卷二). Learners must first cultivate their own virtue, then establish a correct life direction, and lay a solid foundation for subsequent endeavors in regulating the family, governing the state, and bringing peace to the world.

朱熹在《大學章句》中明確劃分："修身以上，明明德之事也；齊家以下，新民之事也。" 格物致知至修身是內聖的 "明明德"工夫，核心在涵養彰顯天賦善性；齊家治國至平天下是外王的 "新民"工夫，核心在將自身德性推廣感化他人。修身是連接二者的樞紐：無修身實踐，內在德性無法真實落地，明明德便流於空洞；無修身基礎，德性無法推廣出去，新民便成無本之木。涵養德性不僅是個人道德修養問題，更是一切社會治理事業的根本前提。

Zhu Xi drew a clear demarcation in his commentary: "The stages from investigating things up to self-cultivation pertain to the work of manifesting the luminous virtue; the stages from regulating the family onward pertain to the work of renewing the people" (Daxue Zhangju). The first five steps are the inner sagehood practices of "manifesting the luminous virtue," aiming to cultivate and manifest the innate good nature; the last three steps are the outer kingship practices of "renewing the people," aiming to influence and transform others through the extension of one's own virtue. Self-cultivation is the pivot connecting these two stages: without its practical transformation, inner virtue cannot be truly manifested, and the work of manifesting the luminous virtue becomes empty talk; without its foundation, virtue cannot be extended outward, and the work of renewing the people becomes a rootless tree.

 五、齊家：涵養德性的家族延伸

 5. Regulation of the Family: The Familial Extension of Cultivating Virtue

齊家是修身的直接延伸，也是外王事業的第一個落地環節。二程、朱熹認為，家庭是社會的最小單位，是德性涵養的重要實踐場所，也是將個人德性推廣為社會道德的第一級階梯；唯有將自身德性推廣於家庭、實現家族和睦教化，才有可能進一步治國平天下。

Regulation of the family is the first level of outward extension for cultivating virtue and the initial tangible link in the outer kingship enterprise. The family is the basic unit of society, the most important practical site for virtue cultivation, and the primary step in expanding personal virtue into social morality. The practice of outer kingship must start from the family: only by extending one's virtue to the family, achieving familial harmony and ethical education, can one gradually accumulate the ability to govern the state and bring peace to the world.

 5.1 齊家的本質：推己之德，化及家人

 5.1 The Essence of Regulating the Family: Extending One's Virtue to Transform Family Members

二程、朱熹將 "齊家" 理解為以自身德性感化全家之人，使之和睦相處、遵守倫理。齊家的本質，是將修身所涵養的德性推廣、感化家族成員，令其在德性滋養下形成良好品格。家庭不是單純的生活場所，而是道德教化的最小單位；家庭成員間的血緣親情，是道德推廣最自然、最便捷的介質。

The Cheng brothers and Zhu Xi defined regulating the family as the act of harmonizing family members and upholding family ethics through the transformative power of one's own virtue. Its essence is to extend the virtue cultivated through self-cultivation to edify family members, fostering their good character through subtle moral influence. The family is not merely a daily living community, but the smallest unit of moral education; the blood ties and natural affection among family members constitute the most spontaneous and convenient medium for the dissemination of morality.

程頤指出："正家之本，在正其身。"（《伊川易傳》）端正家庭的根本在端正自身德性言行。治家不能靠空洞說教，更不能靠強制手段，必須以自身德性感化引導家人。家人朝夕相處，自己的一言一行皆被看在眼裡；自身德性涵養深厚、言行自然合道德，家人便自然受感化、主動效仿；反之，自身德性不足、言行不合道德，卻要求家人遵守道德，言辭再動聽也無法令人真心信服，家庭必然治理不好。

Cheng Yi stated: "The foundation of regulating the family lies in rectifying one's own person" (Yichuan Yizhuan伊川易傳). Governing the family does not rely on strict family rules or harsh punishment, but on the moral example of the cultivator himself. Family members live in close quarters, and every word and deed of the family head is observed by all. If one's virtue is profound and one's conduct spontaneously aligns with morality, family members will naturally be influenced and voluntarily emulate such behavior. Conversely, if one's own virtue is deficient and one's conduct violates moral principles, yet one demands moral compliance from family members, no matter how eloquent the words, they will not inspire genuine conviction, and the family will inevitably fall into disorder.

朱熹在《大學章句》中細化此邏輯，認為齊家的核心是 "推己之德，以化家人"：將修身所得孝、悌、慈三種基本德性推廣於家族 —— 以事父母之孝道教化家族晚輩，以敬兄長之悌心教化同輩，以慈育子女之慈心教化長幼。此三德是做人根本，也是家庭倫理核心；能在家族中充分推廣，令所有成員受德性感化，家族自然和睦有序，也才具備進一步治國的真實基礎。

Zhu Xi refined this logic in his commentary, positing that the core of regulating the family is "extending one's own virtue to transform family members" (Daxue Zhangju大學章句). The specific content of this extension is the three fundamental virtues of filial piety, fraternal respect, and parental kindness cultivated in self-cultivation: serving parents with filial piety to edify the younger generation; respecting elder brothers with fraternal respect to edify peers; nurturing children with parental kindness to edify all family members. These three virtues are the foundation of all human conduct and the core of family ethics. If fully promoted within the family, inspiring moral transformation in all members, the family will naturally achieve harmony and order, laying a solid foundation for further governance of the state.

 5.2 家國同構：德性涵養的由內及外邏輯

 5.2 The Isomorphism of Family and State: The Outward Extension Logic of Cultivating Virtue

二程、朱熹繼承儒家 "家國同構" 思想，這是涵養德性從修身延伸至齊家、再延伸至治國的邏輯紐帶。家庭是國家的縮小版，國家是家庭的放大版；家庭治理的道德邏輯與國家治理的道德邏輯完全一致。

The theoretical basis for connecting family regulation with state governance is the traditional Confucian idea of the isomorphism of family and state. This view holds that the family is a microcosm of the state, and the state is an enlarged family; the moral logic of family governance and state governance is completely consistent, and the ethical principles of family governance can be directly extended to the field of state governance.

程顥提出 "為政之道，以順民心為本，以厚民生為本，以安而不擾為本"（《代呂晦叔應詔疏》），而這一治國邏輯的源頭恰在家庭治理：家庭中講 "父慈子孝"，推廣至國家，君主對百姓當如父母對子女般慈愛，百姓對君主當如子女對父母般孝順；家庭中講 "兄友弟恭"，推廣至國家，官員對百姓當如兄長對弟弟般友愛，百姓對官員當如弟弟對兄長般恭敬。治國的根本道德準則，其實就是家庭倫理的道德延伸；而家庭倫理的根源，又在個人自身的德性涵養。

Cheng Hao elaborated on this isomorphic relationship from the perspective of political governance. He proposed: "The way of governance takes according with the people's hearts as its root, enriching the people's livelihood as its root, and peace without disturbance as its root" (Dai Lü Hui Shu Ying Zhao Shu代呂晦叔應詔疏). This political logic actually originates from the ethical logic of family governance. The family ethic of "parental affection and filial piety" extends to the state: the ruler should love the people as parents love their children, and the people should be filial to the ruler as children are filial to their parents; the family ethic of "brotherly friendship and respect" extends to the state: officials should love the people as elder brothers love their younger brothers, and the people should respect officials as younger brothers respect their elder brothers. The fundamental moral norms of state governance are merely an extension of family ethics.

朱熹在《大學章句》中將 "家國同構" 闡釋得更為透徹："家齊而後國治" 的核心原因，在於家庭治理的德性可直接平移推廣至國家治理。君子不必走出家門，便能在國內完成道德教化 —— 他在家庭中的孝、悌、慈行為本身就是治國的道德示範：事父母之孝心可直接移植為事君主之忠心，敬兄長之悌心可移植為尊重長者之恭順，慈育子女之慈心可移植為治理百姓之愛民。連家族成員都不能以德性感化、連家庭關係都處理不好的人，其德性涵養必有嚴重缺陷，根本不可能將德性推廣於天下百姓；唯有先實現家庭和睦教化、驗證了自身德性推廣能力，才有資格有能力進一步治國。

Zhu Xi explicated the isomorphism of family and state more thoroughly in his commentary. He believed that the core reason "the regulated family precedes the orderly state" is that the virtue exercised in family governance can be directly transferred and applied to state governance. The noble person need not leave his home to achieve moral transformation throughout the state—his conduct of filial piety, fraternal respect, and parental kindness within the family itself serves as a direct moral example for governance. The filial piety shown to parents can be directly transplanted into loyalty to the ruler; the fraternal respect shown to elder brothers can be transformed into respect for the elderly; the parental kindness shown to children can be converted into benevolent governance over the people. Anyone who cannot edify his family members with virtue or handle family relations properly must have serious deficiencies in virtue cultivation, making it impossible for him to extend virtue to the people of the state.

 5.3 德化家人：涵養德性的日常教化

 5.3 Moral Transformation of Family Members: Daily Edification in Cultivating Virtue

齊家不是靠強制家規、嚴厲懲罰實現的，而是靠自身德性在日常家族生活中的潛移默化。二程認為，家族教化的核心在以身作則、以行感人。程頤在《伊川易傳》中強調 "治家之道，以正身為本"，自身正，則家人不令而行；事父母時和顏悅色、體貼入微，與兄長相處時恭敬謙讓、態度誠懇，教育子女時慈愛有度、以身作則 —— 這些日常細微舉動就是最好的家族教化方式。在家族中踐行德性不可有絲毫刻意虛偽：表面做出合道德的樣子，內心卻無真實德性，家人必然心生排斥，無法達到教化效果；唯有發自內心的真實德性表現，才能對家人產生真實感化。

The key to regulating the family lies in the daily edification of family members, rather than formalistic family rules or coercive punishment. The core of this edification is the subtle, imperceptible influence of one's own virtue in daily family life. The Cheng brothers stressed that the key to edifying family members lies in setting an example and influencing others through practical deeds, rather than empty moral preaching. In his Commentary on the Book of Changes, Cheng Yi emphasized: "The way of regulating the family takes rectifying one's own person as the foundation" (Yichuan Yizhuan伊川易傳). If one's own conduct is upright and in line with moral principles, family members will follow suit without the need for explicit orders; conversely, if one's own conduct is improper, even the most severe family rules will not achieve the desired effect. The daily details of family life are the most important carrier of moral edification: treating parents with gentle words and thoughtful care, interacting with elder brothers with deference and sincerity, educating children with affectionate discipline and personal example—these trivial daily acts are the most effective way to edify family members. The practice of virtue within the family must be devoid of hypocrisy: if one merely feigns moral conduct on the surface while lacking genuine virtue within, family members will inevitably feel repelled, making moral transformation impossible.

朱熹補充說，以德性感化家人是長期循序漸進的過程，須在日常家族起居中持續踐行。飲食起居、人際交往、處理家族事務時，時刻以道德準則為先，將德性滲透到每一個細節；久而久之，家人在耳濡目染中自然被感化，主動效仿道德行為。家族中的教化也是對自身德性涵養的進一步檢驗：能在家族中克服私情偏好、以公正道德準則對待所有成員，說明德性涵養已足夠成熟；反之，只偏愛親近之人、對其他成員冷漠粗暴，說明德性涵養仍有嚴重不足，須繼續下工夫修鍊。

Zhu Xi added that edifying family members through virtue is a gradual, long-term process that must be sustained in the daily routine of family life. It cannot be achieved through occasional good deeds or temporary deliberate restraint. In every detail of clothing, food, housing, transportation, social interaction, and family affair management, one must prioritize moral principles, infusing virtue into every aspect of daily life. Over time, family members are unconsciously influenced by what they see and hear, spontaneously emulating moral behavior. Moreover, the process of edifying family members is also a further test of one's own virtue cultivation: if one can overcome personal partiality and treat all family members with impartial moral standards, it indicates that one's virtue cultivation is sufficiently mature; conversely, if one shows favoritism to close relatives and is cold or rude to other family members, it reveals significant deficiencies in virtue cultivation, requiring continued diligent practice.

 六、治國理政：涵養德性的政治延伸

 6. Governance of the State: The Political Extension of Cultivating Virtue

治國是齊家的進一步延伸，也是外王事業的核心環節。二程、朱熹認為，國家治理的本質不是靠強權武力、規章制度約束民眾，而是靠君主與官員自身的德性感化引導民眾；涵養德性是治國理政的根本前提，也是國家長治久安的底層保障。

Governance of the state is the further extension of regulating the family in the outer kingship enterprise and the core link connecting personal virtue cultivation with public political governance. The essence of state governance lies not in coercive military might or institutional regulations to restrain the people, but in the moral influence of the ruler and officials to guide the people. Virtue cultivation is the fundamental prerequisite for state governance and the underlying guarantee for the country's long-term stability and security.

 6.1 為政以德：涵養德性是治國的根本基礎

 6.1 Governance Through Virtue: Cultivating Virtue as the Fundamental Foundation of State Governance

二程、朱熹繼承儒家 "為政以德" 傳統，將德性涵養視為治國理政的根本基礎。政治的本質是道德的延伸，治國的根本方法不是嚴刑峻法或權術謀略，而是執政者以自身德性為民眾做出道德表率，感化引導民眾自發遵守道德，從而實現天下太平。

The Cheng brothers and Zhu Xi inherited the traditional Confucian political doctrine of governance through virtue, regarding virtue cultivation as the fundamental basis of state governance. The essence of politics is the extension of morality; the fundamental method of governance is not harsh punishment or political strategy, but the ruler setting a moral example for the people, inspiring them to spontaneously abide by moral norms, thereby achieving universal peace.

程顥提出 "治天下以正風俗、得賢才為本"，而這一根本的源頭仍在執政者自身的德性涵養：欲令國家風俗淳厚、百姓遵守道德，須先由執政者做出道德表率；欲令國家得到賢能人才，須先由執政者自身具備德性，方能感化吸引有德之才。程頤則明確政治與道德的直接關聯："政在修己，身正則官治。"（《二程粹言》）治理國家的根本原則在端正自身德性；自身德性深厚、言行合道德，民眾自然被感化，國家便能得到治理；反之，執政者自身德性不足、言行不合道德，卻要求民眾遵守道德，即便制定嚴苛法律也無法令民眾真心信服，國家必陷入混亂。

Cheng Hao stated: "Governing the world takes rectifying social customs and securing worthy talents as its foundation." The source of this foundation still lies in the virtue cultivation of the ruler: to foster pure social customs and ensure popular moral compliance, the ruler must first set a moral example; to acquire virtuous and talented individuals, the ruler must first possess virtue himself to attract and inspire worthy people. Cheng Yi clarified the direct connection between politics and morality: "Governance rests on cultivating oneself; if one's own conduct is upright, the officials will be orderly" (Er Cheng Cuiyan二程粹言). The fundamental principle of governing the state lies in rectifying one's own virtue. If the ruler's virtue is profound and his conduct aligns with morality, the people will naturally be influenced, and the state will be well-governed. Conversely, if the ruler's virtue is deficient and his conduct violates moral principles, yet he demands moral compliance from the people, even the enactment of harsh laws will not inspire genuine conviction, and the state will inevitably fall into chaos.

朱熹在《大學章句》中將此邏輯表述得更為透徹："一家仁，一國興仁；一家讓，一國興讓；一人貪戾，一國作亂。" 執政者在家族中踐行仁德，全國民眾便被感化、興起仁愛之風；執政者在家族中謙讓有禮，全國民眾便效仿、興起謙讓之風；反之，執政者自身貪婪暴戾、違背道德，全國民眾便受負面影響，社會必陷入動亂。執政者的德性涵養是國家治理的核心關鍵；政治的本質，就是執政者將自身涵養的德性推廣於整個國家的過程。

Zhu Xi articulated this logic more thoroughly in his commentary. He believed that the key to state governance lies in the ruler extending the virtue cultivated through self-cultivation to the entire nation, influencing the people with moral character rather than controlling them with power or laws. He said: "When one family practices benevolence, the entire state will rise in benevolence; when one family practices deference, the entire state will rise in deference; if one person is greedy and cruel, the entire state will fall into chaos" (Daxue Zhangju大學章句). The ruler's every word and deed has a demonstration effect on the entire country: if the ruler practices virtue within his family, the people of the state will be influenced to embrace benevolence; if the ruler is modest and courteous within his family, the people will follow suit and practice deference; conversely, if the ruler himself is greedy, cruel, and violates moral principles, the people will be negatively affected, and society will fall into turmoil.

 6.2 德主刑輔：涵養德性的治理方式

 6.2 Virtue as Primary, Punishment as Auxiliary: The Governance Approach Rooted in Cultivating Virtue

在具體治理實踐中，二程、朱熹雖不否認法律的震懾作用，但始終堅持"德主刑輔"——以道德教化為治國主要方法，刑罰僅為輔助手段。這一治理方式的底層邏輯，仍基於德性涵養的感化原則。

In the specific practice of state governance, the Cheng brothers and Zhu Xi did not deny the deterrent role of law and punishment, but consistently adhered to the political principle of "virtue as primary, punishment as auxiliary"—taking moral edification as the main method of governance and punishment as a supplementary means. The underlying logic of this governance approach rests on the transformative power of virtue cultivation.

二程認為，治國的核心任務是 "教化百姓，變化氣質"，而實現這一目標的根本路徑是執政者自身的德性表率與基於德性的道德教化。刑罰只能在民眾犯罪後起懲罰作用，無法從根本上令民眾產生羞恥之心；唯有通過德性教化，在民眾內心種下道德種子，令其從根本上厭惡惡行、樂於行善，才能實現國家長治久安。

The core task of governance is "edifying the people and transforming their physical endowment" (Er Cheng Yishu二程遺書). The goal of governance is not to punish crimes, but to transform the people's physical endowment through moral education, cultivate their moral consciousness, and make them spontaneously abide by social norms. In this process, punishment can only play a passive deterrent role after crimes have been committed; it cannot solve the root problem of immoral behavior. Only through virtue cultivation can moral seeds be planted in the hearts of the people, inspiring them to inherently abhor evil and delight in doing good, thereby achieving the country's long-term stability and security.

朱熹將 "德"與"刑" 的關係比作 "根"與 "葉"：德性是治理的根本，如樹木之根；刑罰是治理的輔助，如樹木之葉——根扎穩了，葉才能茂盛；無德性教化而只靠刑罰治國，如同無根之木，無法長久存活。他在《大學章句》中詳述德性教化的具體方式：執政者須將自身涵養的仁、義、禮、智、信等德性貫徹於所有政策與日常行為中；起用提拔有德賢人，令其擔任官職教化百姓；制定合道德準則的禮樂制度，潛移默化熏陶感化百姓。通過自上而下的德性推廣，逐步令全國民眾明曉道德倫理、修養德性、主動放棄惡行。刑罰只能是道德教化無效後的補充手段；執政者不優先推行德政而依賴嚴苛刑罰，即便短期內社會穩定，也無法長久維持，更不可能實現真正的天下大治。

Zhu Xi compared the relationship between virtue and punishment to that of roots and leaves: virtue is the root of governance, like the roots of a tree; punishment is the auxiliary, like the leaves. Only when the roots are firm can the leaves flourish; governing the state solely by punishment without virtue edification is like a rootless tree that cannot survive for long (Daxue Zhangju大學章句). He detailed the specific methods of virtue edification: the ruler must permeate all policies and daily conduct with the virtues of benevolence, righteousness, propriety, wisdom, and trustworthiness cultivated through self-cultivation; appoint and promote virtuous talented individuals to serve as officials and edify the people; establish ritual and musical institutions that accord with moral norms to subtly influence and transform the people. Through top down promotion of virtue, the people are gradually guided to understand moral ethics, cultivate virtue, and voluntarily renounce evil deeds. Punishment can only be a supplementary measure when moral edification fails; if the ruler does not prioritize the implementation of benevolent governance but relies on harsh punishment, even if social order is maintained in the short term, it cannot be sustained in the long run, let alone achieve true universal peace.

 6.3 保民愛民：涵養德性的政治價值取向

 6.3 Protecting and Loving the People: The Political Value Orientation of Cultivating Virtue

在二程、朱熹的政治理論中，涵養德性不是執政者的個人修身愛好，而必須體現為 "保民愛民" 的政治價值取向與相應的仁政措施—— 這是德性涵養在政治層面的真實驗證標準，也是治國理政的核心價值指向。

In the political theories of the Cheng brothers and Zhu Xi, cultivating virtue is not a personal spiritual pursuit of the ruler, or a formalistic political performance; it must be embodied in the political value orientation of protecting and loving the people and corresponding benevolent policies. This is the criterion for verifying the authenticity of the ruler's virtue cultivation in the political realm and the core value orientation of state governance.

程顥 "為政三本" 思想 ——"為政之道，以順民心為本，以厚民生為本，以安而不擾為本"——的本質，即將執政者的德性落實為愛民的政治措施：順民心，即順應民眾真實意願，不憑個人私慾制定政策；厚民生，即保障民眾基本生活需求，令其豐衣足食；安而不擾，即減少對民眾的過度打擾，令其安居樂業。這 "三本" 是執政者德性在政治實踐中的必然體現：德性涵養深厚，自然將民心向背作為治理出發點，將民眾福祉作為政策核心目標；反之，不顧民眾生活需求、一味滿足私慾甚至剝削壓迫民眾，說明德性涵養有嚴重缺陷，根本不配居於執政地位。

The essence of Cheng Hao's doctrine of the "three foundations of governance"—"The way of governance takes according with the people's hearts as its root, enriching the people's livelihood as its root, and peace without disturbance as its root"—lies in translating the ruler's virtue into loving political measures. "According with the people's hearts" means respecting the people's true wishes and formulating policies based on public will rather than personal selfish desires; "enriching the people's livelihood" means guaranteeing the people's basic subsistence needs and ensuring their ample food and clothing; "peace without disturbance" means reducing excessive intrusion into the people's lives and enabling them to live and work in peace and contentment. These three foundations are the inevitable manifestation of the ruler's virtue in political practice: if the ruler's virtue cultivation is profound, he will naturally take public sentiment as the starting point of governance and the people's wellbeing as the core goal of policymaking. Conversely, if the ruler ignores the people's livelihood, prioritizes the satisfaction of personal selfish desires, or even exploits and oppresses the people, it reveals serious deficiencies in his virtue cultivation, disqualifying him from the ruling position.

朱熹承接此民本思想，在《大學章句》中指出執政者的德性涵養必須體現為 "絜矩之道"—— 將心比心、以身作則的恕道精神："所惡於上，毋以使下；所惡於下，毋以事上。" 不喜歡上層以無禮態度對待自己，便不以無禮態度對待下層民眾；不喜歡下層以不忠誠態度對待自己，便不以不忠誠態度對待上層君主。這種絜矩之道是仁愛德性在政治實踐中的具體體現：執政者須將自己對美好生活的嚮往推己及人，體察民眾真實願望，保障民眾基本利益，施行仁政、減輕負擔，令民眾安居樂業。做到這一點，執政者的德性涵養才算在政治層面真實落地，國家也才能真正實現大治。

Zhu Xi inherited this people-centered thought and pointed out in his commentary that the ruler's virtue cultivation must be embodied in "the way of the measuring square"—the spirit of reciprocity and empathy. He quoted The Great Learning: "What one dislikes in superiors, one should not use to treat subordinates; what one dislikes in subordinates, one should not use to treat superiors" (Daxue Zhangju大學章句). This requires the ruler to empathize with the people, treat the people's interests as his own, and not impose on the people what he himself does not desire. The way of the measuring square is the concrete manifestation of benevolent virtue in political practice: the ruler must extend his own desire for a good life to others, understand the people's true aspirations, protect their basic interests, implement benevolent governance, reduce excessive burdens, and enable the people to live and work in peace and contentment. Only by achieving this can the ruler's virtue cultivation be truly realized in the political realm, and can the state achieve genuine great order.

 七、平天下：涵養德性的終極外王境域

 7. Bringing Peace to the World: The Ultimate Outer Kingship Domain of Cultivating Virtue

平天下是聖賢之道的終極外王目標。二程、朱熹所論 "平天下" 雖本於傳統 "天下" 概念，但其 "明明德於天下" 的治理邏輯、以德性教化為核心的公共治理法則，可延伸為現代全球治理的價值準則。在其理論體系中，涵養德性是實現天下太平的根本前提，也是連通內聖境界與外王事業的終極紐帶。

Bringing peace to the world is the ultimate outer kingship goal of the sagehood path. Although the concept of "bringing peace to the world" proposed by the Cheng brothers and Zhu Xi is rooted in the traditional Chinese notion of "all under heaven," its governance logic of "manifesting the luminous virtue throughout the world" and public governance norms centered on virtue cultivation can be extended to the value criteria of modern global governance. In their theoretical system, cultivating virtue is the fundamental prerequisite for achieving world peace and the ultimate bond connecting inner sagehood and outer kingship.

 7.1 平天下的本質：涵養德性，推行王道

 7.1 The Essence of Bringing Peace to the World: Cultivating Virtue and Implementing the Kingly Way

二程、朱熹將 "平天下" 理解為使天下之人皆有以明其明德、各得其所、和諧相處。平天下的本質不是靠強權武力一統天下，也不是靠制度法律強行統一秩序，而是通過聖賢的德性教化，令天下所有人喚醒自身本有善性、提升德性涵養，最終實現萬民各得其所、沒有不平的理想狀態。

The Cheng brothers and Zhu Xi defined bringing peace to the world as the ideal state in which all people under heaven manifest their innate good nature through virtue cultivation, each obtains his proper place in society, and all live in harmony without conflict or injustice. Its essence lies not in unifying the world through military force or imposing international order through formal institutions, but in the moral transformation of the entire human race: through the virtue edification of sages, all people in the world awaken their innate good nature and improve their virtue cultivation, thereby voluntarily abandoning aggression and oppression and realizing universal harmony.

這一理想狀態的核心支撐，是聖賢德性涵養與推廣的極致。程頤在《易傳》中釋 "乾" 卦時指出，聖人 "與天地合其德，與日月合其明"，其德盛至此，自然 "先天而天弗違，後天而奉天時"。聖人以盛德臨天下，民眾自然歸往；這不是靠武力征服或強權威懾，而是靠聖人極致的德性涵養實現對天下民眾的極致感化。聖人德性涵養達於極致，便自然成為天下人共同效仿的道德標準，天下太平也便自然實現。

The core pillar of this ideal state is the ultimate cultivation and promotion of the sage's virtue. In his Commentary on the Book of Changes, Cheng Yi stated that the sage "unites his virtue with that of heaven and earth, and matches his brilliance with that of the sun and moon" (Yichuan Yizhuan伊川易傳). When the sage's virtue reaches this pinnacle, he naturally acts in complete accordance with the moral law of the universe. When the sage governs the world with supreme virtue, the people will naturally turn to him—this is achieved not through military conquest or deterrence, but through the ultimate moral influence of the sage's perfected virtue. When the sage's virtue cultivation reaches its zenith, he naturally becomes the universal moral exemplar for all people under heaven, and world peace is thereby spontaneously achieved.

朱熹補充這一邏輯的底層依據：平天下的關鍵在 "明明德於天下"—— 執政者（聖人）先自明其明德，再推己及人，令天下之人皆明其明德。當執政者具備極致的德性涵養、能將德性徹底推廣於天下民眾，令天下所有人皆具備穩定道德品格、自覺踐行道德善待他人，天下之間自然不會有衝突、戰爭與不公平，便能實現太平的終極理想。

Zhu Xi supplemented the underlying logic: the key to bringing peace to the world lies in "manifesting the luminous virtue throughout the world" (Daxue Zhangju大學章句). This is a process of continuous outward extension of virtue: the ruler (sage) first manifests his own innate good nature through virtue cultivation, then extends this virtue to others through governance practice, enabling all people under heaven to likewise manifest their innate goodness and achieve moral self-improvement. When the ruler possesses perfected virtue and can fully extend this virtue to the people of the world—inspiring all people to cultivate stable moral character and spontaneously practice benevolence toward others—conflicts, wars, and injustice will naturally vanish, and the ultimate ideal of universal peace will be realized.

 7.2 絜矩之道：涵養德性的天下推廣法則

 7.2 The Way of the Measuring Square: The Universal Promotion Rule of Cultivating Virtue

實現平天下的核心方法，是《大學》所說的 "絜矩之道"——"恕道"的極致延伸，也是涵養德性在天下層面的具體推廣法則。

The core method to achieve world peace is the way of the measuring square elucidated in The Great Learning—the utmost extension of the principle of reciprocity and the concrete rule for promoting virtue cultivation globally. This rule transforms the abstract requirement of virtue cultivation into a concrete operational norm for international governance.

朱熹《大學章句》釋 "絜矩之道"："絜，度也；矩，所以為方也。" 通俗而言，就是 "將心比心、推己及人" 的恕道準則：自己希望得到的，也主動給予別人；自己厭惡的，也不施加給別人。他細化其具體內容："所惡於上，毋以使下；所惡於下，毋以事上；所惡於前，毋以先後；所惡於後，毋以從前；所惡於右，毋以交於左；所惡於左，毋以交於右。" 對待上下、前後、左右各個方向的人，都以自己的感受為掂量標準，不將自己厭惡的處事方式施加給任何人；無論對待本國民眾還是其他國家民眾，都遵循這一統一道德標準。

In his commentary, Zhu Xi explained: "The measuring square is used to measure what is right. It means empathizing with others and treating others as one would wish to be treated" (Daxue Zhangju大學章句). This is a universal moral principle applicable to all people: one should bestow upon others what one oneself desires, and refrain from imposing on others what one oneself detests. He further detailed its specific content: "What one dislikes in superiors, one should not use to treat subordinates; what one dislikes in subordinates, one should not use to treat superiors; what one dislikes in those ahead, one should not use to treat those behind; what one dislikes in those behind, one should not use to treat those ahead; what one dislikes in those to the right, one should not use to treat those to the left; what one dislikes in those to the left, one should not use to treat those to the right." In essence, this requires that in global governance, ruling subjects take the protection of the people's interests as the core starting point, treat the people of different nations and ethnic groups as equals, and not impose their own will on others.

絜矩之道本質上是涵養德性的 "恕道" 精神在天下層面的極致延伸。一個人涵養了德性，便必然有 "將心比心" 的自覺；將這種自覺從家庭推廣到國家，再從國家推廣到全世界，便會在天下治理中尊重不同國家、不同民族的民眾，體察所有人的真實意願，不將自己意志強加於人，平等對待所有國家和地區。如果天下執政者都能遵循這一基於德性的恕道準則，以自身德性感化其他國家而非以武力霸權壓制，國際社會自然實現公平正義，不同國家民族之間自然和諧相處，世界才能真正和平，平天下的終極理想才能落地。

The way of the measuring square is essentially the utmost extension of the reciprocity inherent in virtue cultivation. When one has cultivated virtue, one spontaneously possesses the consciousness of "empathizing with others"; extending this consciousness from one's family to one's state, and further from one's state to the entire world, will foster respect for the people of different nations and ethnic groups in global governance, empathy for the genuine aspirations of all people, rejection of power politics and hegemony, and equal treatment of all countries and regions. If all ruling figures worldwide abide by this virtue-based principle of reciprocity—prioritizing moral influence over military or economic coercion—the international community will naturally achieve fairness and justice, diverse nations and ethnic groups will coexist in harmony, genuine world peace will be realized, and the ultimate goal of bringing peace to the world will be achieved.

 7.3 天人合一：涵養德性的聖賢終極境界

 7.3 The Unity of Heaven and Humanity: The Ultimate Sagehood Realm of Cultivating Virtue

平天下不是單純的政治功業，而是聖人德性涵養的極致外發；平天下的治理實踐也反過來驗證、成就聖人的完整人格 ——二者 "體用一源，顯微無間"，共同構成聖賢之道的終極境域。

Bringing peace to the world is not merely a political enterprise or the external result of virtue cultivation; more importantly, it is the ultimate confirmation and consummation of the sage's personal virtue. The perfect unity of inner virtue cultivation and outer political practice constitutes the ultimate realm of the sagehood path—the unity of Heaven and humanity.

這一終極境域的底層邏輯，是 "天理" 與 "人性" 的徹底貫通。二程、朱熹皆主 "性即理也"，人的德性是天理在人身上的具體體現；聖人之所以為聖，在於其德性涵養已達極致，完全復歸天賦本性，徹底做到與天理融為一體，一言一行皆自然符合天理法則，無需刻意思考、勉強實踐，便能自然而然踐行合道德行為，實現 "從心所欲不逾矩" 的道德自由。

The underlying logic of this ultimate realm is the complete interconnection between the Heavenly Principle and human nature. Both Cheng Yi and Zhu Xi maintained that "human nature is principle" (Er Cheng Yishu二程遺書); human virtue is the concrete manifestation of the Heavenly Principle—the universal moral law of the universe—in the individual. The sage is defined by his perfected virtue cultivation: he has fully restored his innate good nature, completely eliminated the bondage of selfish desires, and brought every word and deed into conformity with the Heavenly Principle. At this realm, the sage does not need to deliberately abide by moral norms or consciously restrain his behavior; his every move naturally conforms to the moral law of the universe, achieving the state of "following his heart's desire without overstepping the bounds" (Lunyu論語).

聖人的極致德性必然外發為平天下的終極功業。聖人內心德性充滿仁民愛物情懷，必然將此情懷推廣於整個天下，令天下所有人乃至天地萬物皆受德性感化；在德性指引下，聖人推行絜矩之道、施行仁政，以道德言行感化天下民眾，令民眾也喚醒天賦善性，一同進入和諧太平的理想狀態。反過來，正是因為完成了平天下的終極功業，聖人的德性涵養才得到最徹底的驗證，實現 "內聖" 與 "外王" 的完整統一。聖賢之道的終極境界是由內而外、內外貫通的：內在涵養德性的極致必然外發為平天下的終極功業，平天下的終極功業也恰恰成就了聖人完整的道德人格。

The sage's perfected virtue will inevitably manifest externally as the ultimate enterprise of bringing peace to the world. The sage's virtue is imbued with a benevolent love for humanity and all things; he will necessarily extend this love to the entire world, inspiring all people and even all things to be influenced by his virtue. Guided by this virtue, the sage implements the way of the measuring square and benevolent governance, influencing the people of the world through moral conduct, inspiring them to awaken their innate good nature, and joining him in the ideal state of universal harmony. Conversely, the sage's virtue cultivation is thoroughly validated precisely by his completion of the ultimate enterprise of world peace—only by achieving this ultimate outer kingship enterprise can the sage's inner virtue cultivation be confirmed as truly perfect. The ultimate realm of sagehood is inherently an integral whole: the perfection of inner virtue cultivation will inevitably manifest externally as the ultimate enterprise of world peace, and the ultimate enterprise of world peace in turn fully consummates the sage's complete moral personality.

從現代視角看，二程、朱熹的 "平天下" 思想可延伸為當代全球治理的價值準則：涵養德性的要求不僅適用於個人、民族國家，也適用於全球治理的所有主體。各國執政者和國際社會應遵循 "絜矩之道"，以自身德性涵養為基礎，以仁愛、平等、忠恕的道德精神為治理價值準則，平等對待世界上所有國家和民族，尊重各國自主選擇，通過道德感化、協商合作解決國際衝突，推動全球社會實現公平正義、和諧太平。

From a modern perspective, the Cheng brothers' and Zhu Xi's theory of bringing peace to the world can be extended to the value criteria for contemporary global governance: the requirement to cultivate virtue applies not only to individuals and nation states, but to all subjects of global governance. Ruling figures worldwide and the international community should abide by the way of the measuring square, taking the moral spirit of benevolence, equality, and reciprocity as the governance criterion, treat all countries and nations as equals, respect the independent choices of all states, resolve international conflicts through moral influence and negotiated cooperation, and promote the international community to achieve fairness, justice, and universal harmony.

 八、涵養德性為貫串聖賢之道的主線

 8. Cultivating Virtue as the Thread Running Through the Entire Sagehood Path

二程、朱熹所建構的聖賢之道，是以 "學為聖賢" 為終極目標、以《大學》八條目為漸進踐履順序、以 "涵養德性" 為核心貫通主線的完整邏輯體系。涵養德性不是某一個修養環節的特定任務，而是貫穿從格物致知到平天下所有條目、連接內聖與外王、貫通知行上下的底層工夫；離開這一主線，整個聖賢之道的修養環節和政治功業便失去道德根基，淪為形式空談。

The sagehood path constructed by the Cheng brothers and Zhu Xi is a complete, rigorous ideological system with clear logical layers and strong practicality. In this system, cultivating virtue is the core connecting thread running through all links: it takes "learning to become a sage" as the ultimate goal, The Great Learning's Eight Steps as the gradual practice sequence, and the unity of "maintaining reverence" and "probing principle to the utmost" as the methodological core. This logical system takes the innate goodness of human nature as its starting point, the practice of "preserving the Heavenly Principle and suppressing human desires" as its main practical line, and the ultimate realm of "the unity of Heaven and humanity, inner sagehood and outer kingship" as its final spiritual pursuit. Without this guiding thread of virtue cultivation, the entire sagehood path and its political endeavors would lose their moral foundation, degenerating into empty formalities.

從內聖修己層面看，涵養德性是修己的核心根本，與格物致知的認知過程互相生髮、彼此促進。格物致知是涵養德性的認知基礎：唯有探究事物背後的天理、明確道德本質內涵，才能在日常中準確存養德性、辨別天理人慾的邊界；涵養德性又是格物致知能取得實效的前提條件：唯有時刻持敬、收斂身心、排除私慾干擾，才能在探究事理時不被主觀偏見和外部慾望迷惑，真正通透認知天理。誠意正心是涵養德性在內心的落實強化：通過慎獨的自覺操持，將天理轉化為內心真實的道德意念，令心始終保持中正，夯實德性內在根基；修身則是涵養德性的日常實踐轉化，將內心德性轉為日常言行的實際道德行為，實現氣質變化，完成內聖階段的人格沉澱。

From the perspective of inner sagehood and self-cultivation, cultivating virtue is the fundamental core of personal spiritual advancement, interacting dynamically with the cognitive process of investigating things and extending knowledge. Investigating things and extending knowledge provide the necessary cognitive foundation: only by rationally exploring the moral principles contained in external things and truly clarifying the essence of universal morality can one accurately distinguish the boundary between the Heavenly Principle and human desires in daily life, making virtue cultivation targeted rather than blind. Virtue cultivation, in turn, is the prerequisite for the effectiveness of investigating things and extending knowledge: only by upholding reverence at all times, restraining body and mind, and eliminating the interference of selfish desires and subjective prejudices can one avoid being confused by the surface of things in exploring principles, thereby achieving a genuine thorough understanding of moral principles. Sincerity of the will and rectification of the mind serve as the internal consolidation and implementation: through the spontaneous discipline of vigilance in solitude, one transforms the external moral principle obtained from investigating things into genuine moral consciousness within the mind, sustains inner impartiality, and consolidates the innate root of virtue. Cultivation of the self constitutes the daily practical transformation: one converts inner moral consciousness into tangible moral conduct in daily life, gradually achieves the thorough transformation of physical endowment, and completes the forging of moral character in the inner sagehood stage.

從內聖外王,修己安人的層面來看，涵養德性是外王事業的本源依據，是連接內聖人格與外王事功的橋樑。齊家是涵養德性的第一外推層級：將自身德性推廣感化家族成員，以孝悌慈的家庭倫理實現家族和睦有序，為治國打下基礎；治國是涵養德性的政治延伸：將家庭倫理的德性邏輯直接平移為國家治理的道德準則，以自身德性表率推行德政、感化民眾，實現國家長治久安；平天下則是涵養德性的極致外發與終極驗證：將仁德推廣於全世界，通過絜矩之道的恕道準則實現全球範圍的和諧太平，完成聖賢的終極外王功業。

From the perspective of outer kingship and governing others, cultivating virtue is the foundational basis of all outer kingship enterprises and the indispensable bridge connecting inner sagehood and outer kingship. Regulation of the family is the first level of outward extension: one edifies family members through the transformative power of virtue, achieves familial harmony via the ethics of filial piety, fraternal respect, and parental kindness, and accumulates the necessary social experience for governance practice. Governance of the state is the political extension: one directly transfers the virtue logic of family ethics to the moral criteria of state governance, implements benevolent governance through the ruler's moral example, inspires the people to abide by morality, and realizes the country's long-term stability and security. Bringing peace to the world is the ultimate outward manifestation and final validation: the sage extends his perfected virtue to the entire world, influences all people with the spirit of benevolence and reciprocity, and achieves universal harmony through the way of the measuring square, thus completing the ultimate outer kingship enterprise.

這一思想體系的邏輯起點是 "人性本善" 的天賦德性預設，邏輯主線是 "存天理、滅人慾" 的德性涵養工夫，邏輯終點是 "天人合一、內聖外王" 的聖人最高境界。在二程、朱熹看來，聖賢不是高不可攀的存在，而是德性涵養達於極致的人格表現；一個人即便沒有外在事功，只要能將自身德性涵養到純粹至善之境，也可在精神境界上達於聖人標準；反之，若無涵養德性，即便擁有再多知識、建立再大外在功業，也無法真正接近聖人境界。

For the Cheng brothers and Zhu Xi, the sage is not an unapproachable transcendent figure, but the natural result of virtue cultivation perfected to the highest degree. The entire Eight Step process is the gradual practice of virtue cultivation: from the cognitive exploration of moral principles, to the internalization of moral consciousness, to the transformation of daily conduct, to the extension of family ethics, to the practice of state governance, and finally to the realization of universal peace—virtue cultivation runs through every link and penetrates the entire process of sagehood practice. This ideological system not only dominated Chinese official thought for more than seven centuries after the Song dynasty, but also provides valuable intellectual resources for modern moral construction and global governance.
