涵养德性：成圣之根基与修齐治平之内核

—— 基于二程、朱熹《大学》八条目式圣贤之道的义理阐释

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

二程与朱熹将 "涵养德性" 视为成就圣贤之道的核心工夫。程颐立 "涵养须用敬，进学则在致知" 为学圣纲领，朱熹进而以 "居敬穷理" 贯通《大学》格物、致知、诚意、正心、修身、齐家、治国、平天下全部条目。以 "学为圣贤" 为标的，德性涵养并非孤立的内心静坐，而是与穷理认知、经世实践双向交织的渐进过程：它是格物穷理的主体条件，是诚意正心的落实处，是修己内圣的根本指向，也是安人外王的本源依据。二程、朱熹通过对《大学》八条目的理学重构，将涵养德性锚定为变化气质、下学上达、终至 "与理为一" 的底层工夫，并以 "絜矩之道" 将传统 "平天下" 转化为基于德性感化的公共治理法则。

The Cheng brothers (Cheng Hao, Cheng Yi程颢，程颐) 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、德性涵养的概念界定与学圣工夫框架

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

作为其圣贤理论的核心，二程与朱熹构建了完整的德性涵养逻辑框架，明确界定了核心概念，并确立了从道德认知到社会实践的渐进过程。该框架以"学为圣贤"为终极目标，以《大学》八条目为基本实践序列，以"敬"与"理"的统一为方法论核心。

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、朱熹论"涵养德性"

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

二程与朱熹以 "存天理、灭人欲" 界定涵养德性的实质：通过诚敬操持与日常熏习，护持并扩充人心中天赋的至善本性，矫正由气禀偏私、物欲遮蔽而生的不良气质。在其理论中，"德性" 即天理在人身上的体现。程颐明言 "性即理也"，天赋人性本善，具足仁义礼智；但此内核易被私心杂念、感官欲望遮蔽，无法自然外发为合天理的行为。"涵养" 便是以 "主敬" 为抓手，时刻收敛身心、专注于理，排除私欲干扰，使本然善性逐步呈现、累积，终至 "诚于中，形于外"。

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二程遗书). 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."

程颐将涵养的核心抓手定为 "敬"，提出"涵养须用敬，进学则在致知"。"敬"不是仪表上的恭敬，而是 "主一之谓敬，无适之谓一"——心始终专注于天理，不向外攀援，不偏离正道。它是一种内在的警觉与操持：既非释氏闭目静坐、隔绝外物的 "空静"，也非僵化拘谨的刻意克制，而是在起心动念、应事接物中保持收敛与郑重。内心持敬，偏邪杂念自然无隙可入，本有善性便得以存养扩充。

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.

朱熹在此基础上将 "涵养" 与 "穷理" 合为进德的 "两轮""两翼"："居敬、穷理二事，互相发。能穷理，则居敬工夫日益进；能居敬，则穷理工夫日益密。"内心持敬，方能不被私欲蒙蔽，集中精神探究事理；穷理既明，对天理的认知愈清晰，敬的工夫也愈扎实。朱熹尤重"敬"的贯通性 —— 从格物致知到治国平天下，无论向内存养还是向外行事，无一处可离敬，所谓"敬字是彻头彻尾工夫，自格物致知，至治国、平天下，皆不外此"。涵养德性由此不是某一阶段的特定任务，而是贯穿八条目、自凡人至圣人全过程的主线。

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大学章句). 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 "学为圣贤"：涵养德性的目标定位

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

二程打破 "圣人天生" 的旧见，断言 "人皆可以至圣人，而君子之学必至于圣人而后已。不至于圣人而后已者，皆自弃也"（《二程遗书》卷二十五）。圣人不是遥不可及的神明，而是普通人通过持续道德修养可企及的最高人格；有志于为学者必以圣人为终极标的，不可半途而废。

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《二程遗书》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.

圣人与凡人的本质分别，不在天赋高低，而在德性涵养是否臻于极致 —— 是否全然保全本然善性、彻底扫除私欲之私，使一言一行皆合天理。程颐在《颜子所好何学论》中径称 "学以至圣人之道也"，将成圣的路径落实为长期的德性涵养。朱熹则以 "复其初" 说圣人之境：通过后天修养恢复天赋至善之本性，而涵养德性正是实现这一恢复的日常工夫。在二程、朱熹的系统中，"学为圣贤" 不是口号，而是涵养德性的具体指向：德性每进一步，便是向圣人境域靠近一步；圣人的最高境域，也必然是涵养德性达于极致的自然结果。

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大学章句). 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 《大学》八条目：涵养德性的践履次第

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

为使涵养德性从抽象的内心修养转化为可执行、可验证的进德路径，二程与朱熹接续《大学》"格物、致知、诚意、正心、修身、齐家、治国、平天下" 八条目，视其为涵养德性由认知而存养、由存养而实践、由实践而推广的完整流程。为学者须循此次第，由内而外、由小及大、由浅入深，一步步踏实做工夫，方能成就圣贤人格。

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《大学章句》中将八条目分作两截：格物、致知、诚意、正心属 "明明德" 的内圣工夫，核心是通过涵养德性明了、恢复本有善性；修身是连接内圣与外王的枢纽；齐家、治国、平天下属 "新民" 的外王工夫，核心是将自身已成之德性推广于家族、国家与天下，以德性感化他人、治理社会。

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.

八条目虽有阶段，却非截然割裂。涵养德性便是串联所有条目的主线：格物致知是其认知基础，诚意正心是其内心落实，修身是其实践转化，齐家治国平天下是其外发延伸。圣贤之道由此从少数人凭天赋企及的高远境界，转为每个普通人都能通过渐进工夫一点一滴涵养德性、逐步实现的可及目标。

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：涵养德性的认知基础与下手处

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

在程朱理学体系中，八条目始于格物致知，被视为德性涵养的认知基础与下手处。道德修养必须建立在对道德原则的理性认知之上；没有这种认知，德性涵养就会沦为盲目的、无目的的形式实践。

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 格物致知的理学本质

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

二程与朱熹对 "格物致知" 的解读，与先儒注疏有本质差异，他们将这一认知方法升级为探究天理、认知善性的道德性认知实践。程颐训 "格" 为 "至"，"如祖考来格之格"，意为深入探究事物本质；又谓 "凡一物上有一理，须是穷致其理"天下万事万物皆有其存在的法则，格物即通过接触、分析日常事物，穷究其背后天理之极致；致知则是令认知不断推扩，终至明理之境。

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、朱熹所谓 "物"，不限于自然事物，更广泛涵盖人伦日用与应事接物之理 —— 这正是格物能连通德性涵养的关键。程颐指出，穷理之途甚多：或读书研讨经典义理，或论古今人物辨别是非，或应事接物斟酌如何方为中正。朱熹补之以 "即物而穷其理"：不脱离具体事物凭空忖度天理，而在事中求理。此 "理" 归根结底与人心本有的德性相通：穷事亲之理，便是明如何尽孝；穷事君之理，便是明如何尽忠；穷交友之理，便是明如何守信。万物之理，最终皆落脚于仁义礼智的道德实践。

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.

格物致知因而是涵养德性的必要前提。不先真切明白善道德理的内涵，所谓涵养便只是盲目的主观死守，甚至误入异端。唯有穷尽事物之理、认清道德本质，涵养中方能精准辨别天理与人欲，正确扩充善性。

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 涵养须用敬：格物致知的前提条件

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

格物致知与涵养德性并非先后脱节，而是互相依存。格物致知是涵养德性的认知基础，涵养德性则是格物致知能取得实效的前提 —— 无敬的涵养，格物致知易陷入心不在焉、认知偏差，无法达到穷理的真实目的。

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.

程颐 "涵养须用敬，进学则在致知" 一语，已将二者绑定。内心庄重收敛、专注集中，无浮躁涣散之杂念，探究事理时方能不被表象迷惑、不被私欲偏见干扰。反之，内心散漫放纵、无持敬基础，格物时心思飘忽，或被外物牵引偏离正道，或被主观成见蒙蔽真相，根本无从深入。

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 "持敬是穷理之本" 深化此义，将居敬与穷理比作两脚、两翼，不可偏废。格物全程须持敬：接触事物之初，以庄重专注态度探究本质；探究之中，收敛身心，不令杂念侵入认知；格物之后，又以敬巩固所得，将外部认知逐步转为内心道德自觉。格物非一蹴可就，须日积月累；而整个积累过程中，敬的工夫不可有丝毫松懈 —— 唯长期持敬，认知方能逐步深入，终至 "豁然贯通"。

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 积累贯通：涵养德性的认知进阶

 2.3 Accumulation and Penetration: The Cognitive Progression of Cultivating Virtue

通过格物致知涵养德性，非顿悟可成，而是由浅入深、由表及里的渐进过程，与德性从认知到扎根、再到扩充的进阶同步。

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.

程颐反对 "只格一物便通众理" 的顿悟，指出 "人谓今日格一件，明日格一件，积习既多，然后脱然自有贯通处"。万物之理散存于无数具体事物中，不可能由一事而尽晓天下之理；须长期持续探究，积累至一定程度，自然对天理形成整体贯通。所谓 "贯通"，并非此后不再格物，而是内心德性已被充分唤醒，能举一反三、触类旁通，将所穷之理与自身善性完整贯通。

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.

朱熹承接此渐进积累说，进一步细化："物格者，物理之极处无不到也；知至者，吾心之所知无不尽也。" 格物就事物之理而言，须穷至极致无遗漏；致知就内心认知而言，须推至极致无模糊。长期积累一旦豁然贯通，便可实现 "众物之表里精粗无不到，而吾心之全体大用无不明"—— 既尽知万物之理，又全然唤醒内心本有善性，使道德本体毫无遮蔽。

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.

这一积累贯通的过程，本质上是德性涵养的一部分。格物之初，为学者所穷是事物表层的外部道理；涵养深入而至贯通，便知 "天理" 与 "人性" 本来贯通 —— 事物之理根源即在人心中本有之善性，格物的终极目的不是获取外部知识，而是印证、扩充内心本有的善性。格物致知的积累，正是德性从认知到自觉的逐步涵养。

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、诚意正心：涵养德性的内在落实

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

格物致知既明天理，圣贤工夫便由对外认知转向对内心性的存养 —— 此即诚意正心的任务。二程、朱熹视诚意正心为涵养德性的关键落地环节，也是连接 "格物致知" 与 "修身齐家" 的枢纽；无此一步，此前所得天理便无法转为真实德性，只沦为空洞知识。

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 诚意：涵养德性的真实落地

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

诚意是衔接 "知" 与 "行" 的节点。朱熹《大学章句》定义诚意："诚其意者，毋自欺也，如恶恶臭，如好好色。" 意念真实无妄，不自欺欺人，如闻恶臭自然厌恶、见好色自然喜爱，无虚伪、无勉强。

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.

程颐指出，诚意的实质是将格物致知所得天理实实在在落实于意念，做到表里如一：知善便发自内心亲近善、践行善，知恶便发自内心厌恶恶、远离恶，不可表面装作好善恶恶，内心却对私欲念念不忘。诚意的核心在 "实"—— 将外部道德认知转为内心真实的道德自觉。做不到这一点，格物所得便只是与己无关的空疏学问，无法形成真正的德性。

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.

做到诚意须依靠敬的涵养。二程谓 "敬是闲邪之道"——"闲" 即防范、制止，敬是防范偏邪私欲入侵内心的方法。人心易被私欲牵引，萌生虚伪不真之意念；唯时刻持敬，心专注于天理，方能从根源杜绝自欺的虚伪意念，自然生发真实道德意念。朱熹补充说，格物致知之后，须以敬警省、把持自心，令好善恶恶的真实意念扎根于内，意念方能真诚，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：涵养德性的心性平衡

 3.2 Rectification of the Mind: The Equilibrium of Moral Psychology

诚意是意念真诚，正心则是德性成熟所需的心性平衡状态。《大学》谓 "身有所忿懥，则不得其正；有所恐惧，则不得其正；有所好乐，则不得其正；有所忧患，则不得其正"。朱熹注曰，忿懥、恐惧、好乐、忧患皆是人心自然产生的情绪，本身并非邪恶；但心若无敬的涵养基础，放纵情绪随意发作，令情绪遮蔽天理之主宰，心便失其平衡，德性也无从稳定存养。

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养。程颐说："敬只是主一也。主一，则既不之东，又不之西，如是则只是中。" 敬令心始终专注，不被外物牵引，不偏向任何一方，自然保持中正。平时以敬涵养身心，应事接物时心自然符合天理准则，不良情绪自然得以节制；若无敬的基础，只靠强行压制情绪，即便暂时有效，也无法长久保持平衡，更无从形成稳定德性。

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.

朱熹细化正心与涵养德性的关联：心是身之主宰，德性是心之主宰；唯以敬涵养，令心时刻被德性主宰，不被情绪牵引、不被私欲遮蔽，方能始终中正。这种正心工夫非一蹴而就，须长期日常体察操持：未接物时收敛身心，警惕私欲萌生；接物时称量轻重缓急，不令情绪左右判断；无论动静，时刻持敬，令天理始终主导内心。如此，德性方能持续存养，逐步形成稳定的道德定力，纵使遭遇外界干扰诱惑，也不轻易偏离天理。

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 慎独：涵养德性的日常操持

 3.3 Vigilance in Solitude: The Daily Discipline of Cultivating Virtue

诚意正心本质上是不依赖外人监督的自觉内在修炼，二程、朱熹以《大学》"慎独" 为其具体操持方法。《大学》论诚意特标 "君子必慎其独也"，朱熹注："君子必慎其独者，盖他人所不及知，而己独知之也。" 在他人看不到、听不到的独处情境中，在只有自己知晓的隐秘念头萌发时，仍保持敬畏，谨慎对待意念，严格依道德准则要求自己，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慎独) 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大学章句). 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.

慎独是涵养德性的关键抓手，也是验证涵养是否有效的标准。公开场合有监督，多数人能刻意表现出合道德的言行；独处时无外界约束，许多人便放松要求，任由不善念头萌发甚至付诸行动。而真正的德性恰在独处细微处存养：独处时能慎独，在细微处警醒持敬、主动排除不善之念、令细微善念逐步扩充，德性便逐渐扎根内心；反之，独处时不能慎独，刻意做掩人耳目之事，此前格物致知工夫便等于落空，德性根本无从涵养。

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.

慎独是 "主敬" 工夫的深化：敬贯穿一切时，慎独便是敬在无外界监督的独处场景下的具体体现。二程谓 "闲邪则诚自存"—— 独处时主动防范制止私欲产生，真诚存养善念，此即慎独的核心，也是诚意正心最真实的落地状态。

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二程遗书). 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：涵养德性的实践枢纽

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

八条目之中，修身是核心枢纽。二程、朱熹认为，修身是涵养德性的直接实践指向，是连接内圣工夫与外王事业的桥梁；格物致知、诚意正心是修身的内在基础，齐家、治国、平天下是修身的自然延伸与外在验证。不能在修身环节落地实践，内在涵养再深厚，也无从成就外王事业。

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 修身的本质：涵养德性，转化气质

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

二程、朱熹所谓 "修身"，非简单的行为规范，而是内在德性的持续涵养与气质的彻底转化。程颐提出 "学至气质变，方是有功"（《二程遗书》卷十八）：为学修养的真正功效，不在知识增长或表面行为合规，而在转化生而带有的偏狭气质，使之与天理相合。凡人之所以偏离道德，根源在于气质有偏颇、易被私欲牵引；修身的本质即以德性涵养工夫不断矫正转化这种偏狭气质，令本有善性全然呈现。

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《二程遗书》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.

朱熹承接此义，将修身释为 "去其私欲之蔽，而复其本然之善"。人天赋本性纯粹至善，但生而具有的气质有清浊偏正之异；这本无善恶，然后天应事接物中，气质受外物牵引、私欲遮蔽，本有善性便无法自然流露，甚至表现为恶的言行。修身的核心即以敬的涵养工夫，一方面克除私欲对善性的遮蔽，逐步减少乃至彻底消除人欲影响；另一方面主动存养扩充本有善性，令善性逐步主导言行，终至气质彻底转化。

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.

修身不是单纯的外在行为矫正，而是以德性涵养为核心的内外整体修炼。二程谓 "有诸中者，必形诸外"—— 内在有德，外在言行自然流露。朱熹注 "修身"引程颐 "敬以直内，义以方外"：以敬涵养令内心正直，以道义令行为合规矩。修身的实质，是通过涵养德性实现内心与外在行为的同步端正，使言行自然合于道德准则。

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二程遗书). 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 克己复礼：涵养德性的实践方法

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

修身实践中，二程、朱熹继承孔子 "克己复礼"，以其为涵养德性的核心实践方法，也是将内在德性转为外在言行的关键路径。"克己" 即克制自身私欲杂念，"复礼" 即令言行合于天理的道德准则。二程谓 "敬胜百邪"（《近思录》卷四），内心诚敬，自然可克服各种私欲干扰；克己的过程本质上也就是涵养德性的过程 —— 私欲与善德对立，私欲减一分，善德便扩充一分，克私愈彻底，涵养愈深厚。

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克己复礼), 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《近思录》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.

朱熹细化这一实践过程：克己复礼须在日常应事接物的小事上实实在在践行，不可有一刻松懈。衣食住行、待人接物的每一个细节中，都要主动约束私欲，令言行完全符合礼的规范 —— 此 "礼" 非外在僵化制度，而是天理在社会生活中的具体体现。要做到 "非礼勿视，非礼勿听，非礼勿言，非礼勿动"：在每一个具体言行上把持住敬的状态，令道德准则贯穿行为细节。

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."

这种践行本质上是对德性涵养的持续强化。日复一日、时时刻刻的约束与训练，外部道德规范逐步转为内心道德自觉，一时的自觉逐步转为稳定的道德习惯；最终无需刻意克制、无需外在监督，言行自然完全合于天理，德性臻于成熟。这正是《大学》"身修而后家齐" 的内在逻辑：唯有完成自身德性涵养，方能进一步教化家人、治理社会。

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 修身为本：涵养德性的价值逻辑

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

《大学》谓 "自天子以至于庶人，壹是皆以修身为本"。二程、朱熹视此为圣贤之道的核心价值逻辑：无论天子还是庶民，无论何种事业地位，皆须以修身为根本前提；而修身的本质又是涵养德性 —— 这意味着涵养德性是所有事业的底层基础，也是成圣成贤的根本落脚点。

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" 逻辑说明修身的核心地位：德性是根本，外在事业是末梢；先立根本，涵养完成自身德性，外王事业才有出发点。不先修身涵养德性而欲教化他人、治理国家，如同不结实之木欲求枝叶繁茂、无基础之建筑欲成高楼，断无可能。程颐以种树为喻："根本须是先培壅，然后可立趋向也"（《近思录》卷二）——种树须先夯实土壤、培好根本，树木方能高大；为学者须先涵养自身德性，方能确立正确人生方向，后续齐家治国平天下才有坚实支撑。

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《近思录》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《大学章句》中明确划分："修身以上，明明德之事也；齐家以下，新民之事也。" 格物致知至修身是内圣的 "明明德"工夫，核心在涵养彰显天赋善性；齐家治国至平天下是外王的 "新民"工夫，核心在将自身德性推广感化他人。修身是连接二者的枢纽：无修身实践，内在德性无法真实落地，明明德便流于空洞；无修身基础，德性无法推广出去，新民便成无本之木。涵养德性不仅是个人道德修养问题，更是一切社会治理事业的根本前提。

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、齐家：涵养德性的家族延伸

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

齐家是修身的直接延伸，也是外王事业的第一个落地环节。二程、朱熹认为，家庭是社会的最小单位，是德性涵养的重要实践场所，也是将个人德性推广为社会道德的第一级阶梯；唯有将自身德性推广于家庭、实现家族和睦教化，才有可能进一步治国平天下。

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 齐家的本质：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、朱熹将 "齐家" 理解为以自身德性感化全家之人，使之和睦相处、遵守伦理。齐家的本质，是将修身所涵养的德性推广、感化家族成员，令其在德性滋养下形成良好品格。家庭不是单纯的生活场所，而是道德教化的最小单位；家庭成员间的血缘亲情，是道德推广最自然、最便捷的介质。

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.

程颐指出："正家之本，在正其身。"（《伊川易传》）端正家庭的根本在端正自身德性言行。治家不能靠空洞说教，更不能靠强制手段，必须以自身德性感化引导家人。家人朝夕相处，自己的一言一行皆被看在眼里；自身德性涵养深厚、言行自然合道德，家人便自然受感化、主动效仿；反之，自身德性不足、言行不合道德，却要求家人遵守道德，言辞再动听也无法令人真心信服，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伊川易传). 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《大学章句》中细化此逻辑，认为齐家的核心是 "推己之德，以化家人"：将修身所得孝、悌、慈三种基本德性推广于家族 —— 以事父母之孝道教化家族晚辈，以敬兄长之悌心教化同辈，以慈育子女之慈心教化长幼。此三德是做人根本，也是家庭伦理核心；能在家族中充分推广，令所有成员受德性感化，家族自然和睦有序，也才具备进一步治国的真实基础。

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大学章句). 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 家国同构：德性涵养的由内及外逻辑

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

二程、朱熹继承儒家 "家国同构" 思想，这是涵养德性从修身延伸至齐家、再延伸至治国的逻辑纽带。家庭是国家的缩小版，国家是家庭的放大版；家庭治理的道德逻辑与国家治理的道德逻辑完全一致。

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.

程颢提出 "为政之道，以顺民心为本，以厚民生为本，以安而不扰为本"（《代吕晦叔应诏疏》），而这一治国逻辑的源头恰在家庭治理：家庭中讲 "父慈子孝"，推广至国家，君主对百姓当如父母对子女般慈爱，百姓对君主当如子女对父母般孝顺；家庭中讲 "兄友弟恭"，推广至国家，官员对百姓当如兄长对弟弟般友爱，百姓对官员当如弟弟对兄长般恭敬。治国的根本道德准则，其实就是家庭伦理的道德延伸；而家庭伦理的根源，又在个人自身的德性涵养。

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代吕晦叔应诏疏). 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《大学章句》中将 "家国同构" 阐释得更为透彻："家齐而后国治" 的核心原因，在于家庭治理的德性可直接平移推广至国家治理。君子不必走出家门，便能在国内完成道德教化 —— 他在家庭中的孝、悌、慈行为本身就是治国的道德示范：事父母之孝心可直接移植为事君主之忠心，敬兄长之悌心可移植为尊重长者之恭顺，慈育子女之慈心可移植为治理百姓之爱民。连家族成员都不能以德性感化、连家庭关系都处理不好的人，其德性涵养必有严重缺陷，根本不可能将德性推广于天下百姓；唯有先实现家庭和睦教化、验证了自身德性推广能力，才有资格有能力进一步治国。

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：涵养德性的日常教化

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

齐家不是靠强制家规、严厉惩罚实现的，而是靠自身德性在日常家族生活中的潜移默化。二程认为，家族教化的核心在以身作则、以行感人。程颐在《伊川易传》中强调 "治家之道，以正身为本"，自身正，则家人不令而行；事父母时和颜悦色、体贴入微，与兄长相处时恭敬谦让、态度诚恳，教育子女时慈爱有度、以身作则 —— 这些日常细微举动就是最好的家族教化方式。在家族中践行德性不可有丝毫刻意虚伪：表面做出合道德的样子，内心却无真实德性，家人必然心生排斥，无法达到教化效果；唯有发自内心的真实德性表现，才能对家人产生真实感化。

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伊川易传). 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.

朱熹补充说，以德性感化家人是长期循序渐进的过程，须在日常家族起居中持续践行。饮食起居、人际交往、处理家族事务时，时刻以道德准则为先，将德性渗透到每一个细节；久而久之，家人在耳濡目染中自然被感化，主动效仿道德行为。家族中的教化也是对自身德性涵养的进一步检验：能在家族中克服私情偏好、以公正道德准则对待所有成员，说明德性涵养已足够成熟；反之，只偏爱亲近之人、对其他成员冷漠粗暴，说明德性涵养仍有严重不足，须继续下工夫修炼。

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、治国理政：涵养德性的政治延伸

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

治国是齐家的进一步延伸，也是外王事业的核心环节。二程、朱熹认为，国家治理的本质不是靠强权武力、规章制度约束民众，而是靠君主与官员自身的德性感化引导民众；涵养德性是治国理政的根本前提，也是国家长治久安的底层保障。

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 为政以德：涵养德性是治国的根本基础

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

二程、朱熹继承儒家 "为政以德" 传统，将德性涵养视为治国理政的根本基础。政治的本质是道德的延伸，治国的根本方法不是严刑峻法或权术谋略，而是执政者以自身德性为民众做出道德表率，感化引导民众自发遵守道德，从而实现天下太平。

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.

程颢提出 "治天下以正风俗、得贤才为本"，而这一根本的源头仍在执政者自身的德性涵养：欲令国家风俗淳厚、百姓遵守道德，须先由执政者做出道德表率；欲令国家得到贤能人才，须先由执政者自身具备德性，方能感化吸引有德之才。程颐则明确政治与道德的直接关联："政在修己，身正则官治。"（《二程粹言》）治理国家的根本原则在端正自身德性；自身德性深厚、言行合道德，民众自然被感化，国家便能得到治理；反之，执政者自身德性不足、言行不合道德，却要求民众遵守道德，即便制定严苛法律也无法令民众真心信服，国家必陷入混乱。

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《大学章句》中将此逻辑表述得更为透彻："一家仁，一国兴仁；一家让，一国兴让；一人贪戾，一国作乱。" 执政者在家族中践行仁德，全国民众便被感化、兴起仁爱之风；执政者在家族中谦让有礼，全国民众便效仿、兴起谦让之风；反之，执政者自身贪婪暴戾、违背道德，全国民众便受负面影响，社会必陷入动乱。执政者的德性涵养是国家治理的核心关键；政治的本质，就是执政者将自身涵养的德性推广于整个国家的过程。

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大学章句). 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 德主刑辅：涵养德性的治理方式

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

在具体治理实践中，二程、朱熹虽不否认法律的震慑作用，但始终坚持"德主刑辅"——以道德教化为治国主要方法，刑罚仅为辅助手段。这一治理方式的底层逻辑，仍基于德性涵养的感化原则。

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.

二程认为，治国的核心任务是 "教化百姓，变化气质"，而实现这一目标的根本路径是执政者自身的德性表率与基于德性的道德教化。刑罚只能在民众犯罪后起惩罚作用，无法从根本上令民众产生羞耻之心；唯有通过德性教化，在民众内心种下道德种子，令其从根本上厌恶恶行、乐于行善，才能实现国家长治久安。

The core task of governance is "edifying the people and transforming their physical endowment" (Er Cheng Yishu二程遗书). 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.

朱熹将 "德"与"刑" 的关系比作 "根"与 "叶"：德性是治理的根本，如树木之根；刑罚是治理的辅助，如树木之叶——根扎稳了，叶才能茂盛；无德性教化而只靠刑罚治国，如同无根之木，无法长久存活。他在《大学章句》中详述德性教化的具体方式：执政者须将自身涵养的仁、义、礼、智、信等德性贯彻于所有政策与日常行为中；起用提拔有德贤人，令其担任官职教化百姓；制定合道德准则的礼乐制度，潜移默化熏陶感化百姓。通过自上而下的德性推广，逐步令全国民众明晓道德伦理、修养德性、主动放弃恶行。刑罚只能是道德教化无效后的补充手段；执政者不优先推行德政而依赖严苛刑罚，即便短期内社会稳定，也无法长久维持，更不可能实现真正的天下大治。

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大学章句). 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 保民爱民：涵养德性的政治价值取向

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

在二程、朱熹的政治理论中，涵养德性不是执政者的个人修身爱好，而必须体现为 "保民爱民" 的政治价值取向与相应的仁政措施—— 这是德性涵养在政治层面的真实验证标准，也是治国理政的核心价值指向。

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.

程颢 "为政三本" 思想 ——"为政之道，以顺民心为本，以厚民生为本，以安而不扰为本"——的本质，即将执政者的德性落实为爱民的政治措施：顺民心，即顺应民众真实意愿，不凭个人私欲制定政策；厚民生，即保障民众基本生活需求，令其丰衣足食；安而不扰，即减少对民众的过度打扰，令其安居乐业。这 "三本" 是执政者德性在政治实践中的必然体现：德性涵养深厚，自然将民心向背作为治理出发点，将民众福祉作为政策核心目标；反之，不顾民众生活需求、一味满足私欲甚至剥削压迫民众，说明德性涵养有严重缺陷，根本不配居于执政地位。

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《大学章句》中指出执政者的德性涵养必须体现为 "絜矩之道"—— 将心比心、以身作则的恕道精神："所恶于上，毋以使下；所恶于下，毋以事上。" 不喜欢上层以无礼态度对待自己，便不以无礼态度对待下层民众；不喜欢下层以不忠诚态度对待自己，便不以不忠诚态度对待上层君主。这种絜矩之道是仁爱德性在政治实践中的具体体现：执政者须将自己对美好生活的向往推己及人，体察民众真实愿望，保障民众基本利益，施行仁政、减轻负担，令民众安居乐业。做到这一点，执政者的德性涵养才算在政治层面真实落地，国家也才能真正实现大治。

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大学章句). 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：涵养德性的终极外王境域

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

平天下是圣贤之道的终极外王目标。二程、朱熹所论 "平天下" 虽本于传统 "天下" 概念，但其 "明明德于天下" 的治理逻辑、以德性教化为核心的公共治理法则，可延伸为现代全球治理的价值准则。在其理论体系中，涵养德性是实现天下太平的根本前提，也是连通内圣境界与外王事业的终极纽带。

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 平天下的本质：涵养德性，推行王道

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

二程、朱熹将 "平天下" 理解为使天下之人皆有以明其明德、各得其所、和谐相处。平天下的本质不是靠强权武力一统天下，也不是靠制度法律强行统一秩序，而是通过圣贤的德性教化，令天下所有人唤醒自身本有善性、提升德性涵养，最终实现万民各得其所、没有不平的理想状态。

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.

这一理想状态的核心支撑，是圣贤德性涵养与推广的极致。程颐在《易传》中释 "乾" 卦时指出，圣人 "与天地合其德，与日月合其明"，其德盛至此，自然 "先天而天弗违，后天而奉天时"。圣人以盛德临天下，民众自然归往；这不是靠武力征服或强权威慑，而是靠圣人极致的德性涵养实现对天下民众的极致感化。圣人德性涵养达于极致，便自然成为天下人共同效仿的道德标准，天下太平也便自然实现。

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伊川易传). 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.

朱熹补充这一逻辑的底层依据：平天下的关键在 "明明德于天下"—— 执政者（圣人）先自明其明德，再推己及人，令天下之人皆明其明德。当执政者具备极致的德性涵养、能将德性彻底推广于天下民众，令天下所有人皆具备稳定道德品格、自觉践行道德善待他人，天下之间自然不会有冲突、战争与不公平，便能实现太平的终极理想。

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大学章句). 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：涵养德性的天下推广法则

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

实现平天下的核心方法，是《大学》所说的 "絜矩之道"——"恕道"的极致延伸，也是涵养德性在天下层面的具体推广法则。

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《大学章句》释 "絜矩之道"："絜，度也；矩，所以为方也。" 通俗而言，就是 "将心比心、推己及人" 的恕道准则：自己希望得到的，也主动给予别人；自己厌恶的，也不施加给别人。他细化其具体内容："所恶于上，毋以使下；所恶于下，毋以事上；所恶于前，毋以先后；所恶于后，毋以从前；所恶于右，毋以交于左；所恶于左，毋以交于右。" 对待上下、前后、左右各个方向的人，都以自己的感受为掂量标准，不将自己厌恶的处事方式施加给任何人；无论对待本国民众还是其他国家民众，都遵循这一统一道德标准。

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大学章句). 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.

絜矩之道本质上是涵养德性的 "恕道" 精神在天下层面的极致延伸。一个人涵养了德性，便必然有 "将心比心" 的自觉；将这种自觉从家庭推广到国家，再从国家推广到全世界，便会在天下治理中尊重不同国家、不同民族的民众，体察所有人的真实意愿，不将自己意志强加于人，平等对待所有国家和地区。如果天下执政者都能遵循这一基于德性的恕道准则，以自身德性感化其他国家而非以武力霸权压制，国际社会自然实现公平正义，不同国家民族之间自然和谐相处，世界才能真正和平，平天下的终极理想才能落地。

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：涵养德性的圣贤终极境界

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

平天下不是单纯的政治功业，而是圣人德性涵养的极致外发；平天下的治理实践也反过来验证、成就圣人的完整人格 ——二者 "体用一源，显微无间"，共同构成圣贤之道的终极境域。

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.

这一终极境域的底层逻辑，是 "天理" 与 "人性" 的彻底贯通。二程、朱熹皆主 "性即理也"，人的德性是天理在人身上的具体体现；圣人之所以为圣，在于其德性涵养已达极致，完全复归天赋本性，彻底做到与天理融为一体，一言一行皆自然符合天理法则，无需刻意思考、勉强实践，便能自然而然践行合道德行为，实现 "从心所欲不逾矩" 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二程遗书); 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论语).

圣人的极致德性必然外发为平天下的终极功业。圣人内心德性充满仁民爱物情怀，必然将此情怀推广于整个天下，令天下所有人乃至天地万物皆受德性感化；在德性指引下，圣人推行絜矩之道、施行仁政，以道德言行感化天下民众，令民众也唤醒天赋善性，一同进入和谐太平的理想状态。反过来，正是因为完成了平天下的终极功业，圣人的德性涵养才得到最彻底的验证，实现 "内圣" 与 "外王" 的完整统一。圣贤之道的终极境界是由内而外、内外贯通的：内在涵养德性的极致必然外发为平天下的终极功业，平天下的终极功业也恰恰成就了圣人完整的道德人格。

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.

从现代视角看，二程、朱熹的 "平天下" 思想可延伸为当代全球治理的价值准则：涵养德性的要求不仅适用于个人、民族国家，也适用于全球治理的所有主体。各国执政者和国际社会应遵循 "絜矩之道"，以自身德性涵养为基础，以仁爱、平等、忠恕的道德精神为治理价值准则，平等对待世界上所有国家和民族，尊重各国自主选择，通过道德感化、协商合作解决国际冲突，推动全球社会实现公平正义、和谐太平。

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、涵养德性为贯串圣贤之道的主线

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

二程、朱熹所建构的圣贤之道，是以 "学为圣贤" 为终极目标、以《大学》八条目为渐进践履顺序、以 "涵养德性" 为核心贯通主线的完整逻辑体系。涵养德性不是某一个修养环节的特定任务，而是贯穿从格物致知到平天下所有条目、连接内圣与外王、贯通知行上下的底层工夫；离开这一主线，整个圣贤之道的修养环节和政治功业便失去道德根基，沦为形式空谈。

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.

从内圣修己层面看，涵养德性是修己的核心根本，与格物致知的认知过程互相生发、彼此促进。格物致知是涵养德性的认知基础：唯有探究事物背后的天理、明确道德本质内涵，才能在日常中准确存养德性、辨别天理人欲的边界；涵养德性又是格物致知能取得实效的前提条件：唯有时刻持敬、收敛身心、排除私欲干扰，才能在探究事理时不被主观偏见和外部欲望迷惑，真正通透认知天理。诚意正心是涵养德性在内心的落实强化：通过慎独的自觉操持，将天理转化为内心真实的道德意念，令心始终保持中正，夯实德性内在根基；修身则是涵养德性的日常实践转化，将内心德性转为日常言行的实际道德行为，实现气质变化，完成内圣阶段的人格沉淀。

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.

从内圣外王,修己安人的层面来看，涵养德性是外王事业的本源依据，是连接内圣人格与外王事功的桥梁。齐家是涵养德性的第一外推层级：将自身德性推广感化家族成员，以孝悌慈的家庭伦理实现家族和睦有序，为治国打下基础；治国是涵养德性的政治延伸：将家庭伦理的德性逻辑直接平移为国家治理的道德准则，以自身德性表率推行德政、感化民众，实现国家长治久安；平天下则是涵养德性的极致外发与终极验证：将仁德推广于全世界，通过絜矩之道的恕道准则实现全球范围的和谐太平，完成圣贤的终极外王功业。

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.

这一思想体系的逻辑起点是 "人性本善" 的天赋德性预设，逻辑主线是 "存天理、灭人欲" 的德性涵养工夫，逻辑终点是 "天人合一、内圣外王" 的圣人最高境界。在二程、朱熹看来，圣贤不是高不可攀的存在，而是德性涵养达于极致的人格表现；一个人即便没有外在事功，只要能将自身德性涵养到纯粹至善之境，也可在精神境界上达于圣人标准；反之，若无涵养德性，即便拥有再多知识、建立再大外在功业，也无法真正接近圣人境界。

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.
