For about 150 years, from the time the Song court moved its capital to the South and reestablished itself there in 1127, North China was ruled by three conquest dynasties—the Liao (907–1125), Xi Xia (1038–1227), and Jin (1115–1234). Although the bureaucracies and political cultures of both Liao and Xi Xia were under Confucian influence, no discernible intellectual developments helped to further the Confucian tradition there. In the Jurchen Jin dynasty, however, despite the paucity of information about the Confucian renaissance in the Southern Song, the Jin scholar-officials continued the classical, artistic, literary, and historiographic traditions of the North and developed a richly textured cultural form of their own. Zhao Bingwen’s (1159–1232) combination of literary talent and moral concerns and Wang Roxu’s (1174–1243) scholarship in Classics and history, as depicted in Yuan Haowen’s (1190–1257) biographical sketches and preserved in their collected works, compared well with the high standards set by their counterparts in the South.

When the Mongols reunited China in 1279, the intellectual dynamism of the South profoundly affected the Northern style of scholarship. Although the harsh treatment of scholars by the conquest Yuan (Mongol) dynasty (1206–1368) seriously damaged the well-being of the scholarly community, outstanding Confucian thinkers nevertheless emerged throughout the period. Some opted to purify themselves so that they could repossess the Way for the future; some decided to become engaged in politics to put their teaching into practice.

Xu Heng (1209–81) took a practical approach. Appointed by Kublai, the Great Khan in Marco Polo’s Description of the World, as the president of the Imperial Academy and respected as the leading scholar in the court, Xu conscientiously introduced Zhu Xi’s teaching to the Mongols. He assumed personal responsibility for educating the sons of the Mongol nobility to become qualified teachers of Confucian Classics. His erudition and skills in medicine, legal affairs, irrigation, military science, arithmetic, and astronomy enabled him to be an informed adviser to the conquest dynasty. He set the tone for the eventual success of the Confucianization of Yuan bureaucracy. In fact, it was the Yuan court that first officially adopted the Four Books as the basis of the civil service examination, a practice that was to be observed until 1905. Thanks to Xu Heng, Zhu Xi’s teaching prevailed in the Mongol period, but it was significantly simplified.

The hermit-scholar Liu Yin (1249–93), on the other hand, allegedly refused Kublai Khan’s summons in order to maintain the dignity of the Confucian Way. To him education was for self-realization. Loyal to the Jin culture in which he was reared and faithful to the Confucian Way that he had learned from the Song masters, Liu Yin rigorously applied philological methods to classical studies and strongly advocated the importance of history. Although true to Zhu Xi’s spirit, by taking seriously the idea of the investigation of things, he put a great deal of emphasis on the learning of the mind. Liu Yin’s contemporary Wu Zheng (1249–1333) further developed the learning of the mind. He fully acknowledged the contribution of Lu Jiuyuan to the Confucian tradition, even though as an admirer of Xu Heng he considered himself a follower of Zhu Xi. Wu assigned himself the challenging task of harmonizing the difference between Zhu and Lu. As a result, he reoriented Zhu’s balanced approach to morality and wisdom to accommodate Lu’s existential concern for self-knowledge. That prepared the way for the revival of Lu’s learning of the mind in the Ming (1368–1644).

The thought of the first outstanding Ming Confucian scholar, Xue Xuan (1389–1464), already revealed the turn toward moral subjectivity. Although Xue was a devoted follower of Zhu Xi, Xue’s Records of Reading clearly shows that he considered the cultivation of “mind and nature” to be particularly important. Two other early Ming scholars, Wu Yubi (1391–1469) and Chen Xianzhang (1428–1500), helped to define Confucian education for those who studied the Classics not simply in preparation for examinations but as learning of the “body and mind.” They cleared the way for Wang Yangming (1472–1529), the most-influential Confucian thinker after Zhu Xi.

As a critique of excessive attention to philological details characteristic of Zhu Xi’s followers, Wang Yangming allied himself with Lu Jiuyuan’s learning of the mind. He advocated the precept of uniting thought and action. By focusing on the transformative power of the will, he inspired a generation of Confucian students to return to the moral idealism of Mencius. His own personal example of combining teaching with bureaucratic routine, administrative responsibility, and leadership in military campaigns demonstrated that he was a man of deeds.

Despite his competence in practical affairs, Wang’s primary concern was moral education, which he felt had to be grounded in the “original substance” of the mind. This he later identified as liangzhi (“good conscience”), by which he meant innate knowledge or a primordial existential awareness possessed by every human being. He further suggested that good conscience as the heavenly principle is inherent in all beings from the highest spiritual forms to grass, wood, bricks, and stone. Because the universe consists of vital energy informed by good conscience, it is a dynamic process rather than a static structure. Human beings can learn to regard heaven and earth and the myriad things as one body by extending their good conscience to embrace an ever-expanding network of relationships.

Wang Yangming’s dynamic idealism, as Wing-tsit Chan, the late dean of Chinese philosophy in North America, characterized it, set the Confucian agenda for several generations in China. His followers, such as the communitarian Wang Ji (1498–1583), who devoted his long life to building a community of the like-minded, and the radical individualist Li Zhi (1527–1602), who proposed to reduce all human relationships to friendship, broadened Confucianism to accommodate a variety of lifestyles.

Among Wang’s critics, Liu Zongzhou (1578–1645) was perhaps the most brilliant. His Human Schemata (Renpu) offered a rigorous phenomenological description of human mistakes as a corrective to Wang Yangming’s moral optimism. Liu’s student Huang Zongxi (1610–95) compiled a comprehensive biographical history of Ming Confucians based on Liu’s writings. One of Huang’s contemporaries, Gu Yanwu (1613–82), was also a critic of Wang Yangming. He excelled in his studies of political institutions, ancient phonology, and classical philology. While Gu was well known in his own time and was honoured as the patron saint of “evidential learning” in the 18th century, his contemporary Wang Fuzhi (1619–92) was discovered 200 years later as one of the most-sophisticated original minds in the history of Confucian thought. His extensive writings on metaphysics, history, and the Classics made him a thorough critic of Wang Yangming and his followers.

The age of Confucianism: Chosŏn-dynasty Korea, Tokugawa Japan, and Qing China

Among all the dynasties, Chinese and foreign, the long-lived Chosŏn (Joseon; also called Yi) in Korea (1392–1910) was undoubtedly the most thoroughly Confucianized. Since the 15th century, when the aristocracy (yangban) defined itself as the carrier of Confucian values, the penetration of court politics and elite culture by Confucianism was unprecedented. Even today—as manifested in political behaviour, legal practice, ancestral veneration, genealogy, village schools, and student activism—the vitality of the Confucian tradition is widely felt in South Korea.

Yi T’oegye (1501–70), the single most-important Korean Confucian, helped shape the character of Chosŏn Confucianism through his creative interpretation of Zhu Xi’s teaching. Critically aware of the philosophical turn engineered by Wang Yangming, T’oegye transmitted the Zhu Xi legacy as a response to the advocates of the learning of the mind. As a result, he made Chosŏn Confucianism at least as much a true heir to Song learning as Ming Confucianism was. Indeed, his Discourse on the Ten Sagely Diagrams, an aid for educating the king, offered a depiction of all the major concepts in Song learning. His exchange of letters with Ki Taesŭng (1527–72) in the famous Four-Seven debate, which discussed the relationship between Mencius’s four basic human feelings—commiseration, shame, modesty, and right and wrong—and seven emotions, such as anger and joy, raised the level of Confucian dialogue to a new height of intellectual sophistication.

In addition, Yi Yulgok’s (1536–84) challenge to T’oegye’s re-presentation of Zhu Xi’s Confucianism, from the perspective of Zhu’s thought itself, significantly enriched the repertoire of the learning of the principle. The leadership of the central government, supported by the numerous academies set up by aristocratic families and by institutions such as the community compact system and the village schools, made the learning of the principle not only a political ideology but also a common creed in Korea.

In Japan, Zhu Xi’s teaching, as interpreted by T’oegye, was introduced to Yamazaki Ansai (1618–82). A distinctive feature of Yamazaki’s thought was his recasting of native Shintōism in Confucian terminology. The diversity and vitality of Japanese Confucianism was further evident in the appropriation of Wang Yangming’s dynamic idealism by the samurai-scholars, notably Kumazawa Banzan (1619–91). It is, however, in Ogyū Sorai’s (1666–1728) determination to rediscover the original basis of Confucian teaching by returning to its pre-Confucian sources that a true exemplification of the independent-mindedness of Japanese Confucians is found. Indeed, Sorai’s brand of ancient learning with its particular emphasis on philological exactitude foreshadowed a similar scholarly movement in China by at least a generation. Although Tokugawa Japan was never as Confucianized as Chosŏn Korea, virtually every educated person in Japanese society was exposed to the Four Books by the end of the 17th century.

The Confucianization of Chinese society reached its apex during the Qing (1644–1911/12), when China was again ruled by a conquest dynasty, in this case Manchu. The Qing emperors outshone their counterparts in the Ming in presenting themselves as exemplars of Confucian kingship. They transformed Confucian teaching into a political ideology, indeed a mechanism of control. Jealously guarding their imperial prerogatives as the ultimate interpreters of Confucian truth, they undermined the freedom of scholars to transmit the Confucian Way by imposing harsh measures, such as literary inquisition. It was Gu Yanwu’s classical scholarship rather than his insights on political reform that inspired the 18th-century evidential scholars. Dai Zhen, the most philosophically minded philologist among them, couched his brilliant critique of Song learning in his commentary “The Meanings of Terms in the Book of Mencius.” Dai Zhen was one of the scholars appointed by the Qianlong emperor in 1773 to compile an imperial manuscript library. That massive scholarly attempt, The Complete Library of the Four Treasures, is symbolic of the grandiose intent of the Manchu court to give an account of all the important works of the four branches of learning—the Classics, history, philosophy, and literature—in Confucian culture. The project comprised more than 36,000 volumes with comments on about 10,230 titles, employed as many as 15,000 copyists, and took 20 years to complete. The Qianlong emperor and the scholars around him may have expressed their cultural heritage in a definitive form, but the Confucian tradition was yet to encounter its most-serious threat.
