Korean Philosophy - Schools of Thought in The Joseon Period

Schools of Thought in The Joseon Period

This dynasty arose out of the military dictatorships and chaos of the preceding era. Transition in this era was from Buddhism to a soldierly approach to Neo-Confucianism. Much work was done, especially on commentaries, and the Chu Hsi school represented indeed the golden age of Korean religious philosophy. Metaphysical research at this time investigated the theological relations between principle (i) and material/vital force (ki), and between as well the four beginnings (sadan), and the seven feelings (ch'ilchong); with the division of the Joseon Confucianists into two leading schools: one on "force" and one on "principles". The philosopher Hwadam ( Suh Kyungduk, 1489–1546 ) moved to integrate i and ki and spoke of Great Harmony (taehwa).

In the Four–Seven Debate with Ki Daesung, Toegye ( Yi Hwang, 1501 – 70 ), while being still dualistic, broke away from Chu Hsi by espousing the reciprocal emanation (hobal) of i and ki: with the Four, ki follows i when i becomes emanant; with the Seven, when ki becomes emanant, i ‘rides’ ki. Though he was critical of Toegye's idea that ki follows i as being dualistic, Yulgok (Yi I, 1536 – 84 ) nevertheless embraced his notion that i ‘rides’ ki: only ki is emanant and i moves its emanation; i and ki are ‘neither two things nor one thing’, as evidenced by ‘wondrous fusion’ (myohap). For Yulgok, original nature (i) and physical nature (ki) coalesce into one human nature. Toegye and Yulgok, whose thoughts culminated in an irenic fusionism, constituted the crowning phase of East Asian neo-Confucianism by exhibiting dialectical dexterity in articulating the concepts of i and ki, left unclarified by the Chinese.

Toegye also developed the neo-Confucianist concept of single-mindedness (kyung), which was a manifestation of his unequivocal humanism, as shown by his total rejection of the Mandate of Heaven (chunmyung), which still had a hold on the Chinese, including Chu Hsi. Toegye's kyung synthesized the primeval Korean sense of supreme-efforts-cum-earnest-devotion (chisung) with the Confucianist notion of holding fast to mind (jik-yung); he advocated self-efforts for creating a meaningful life. In particular, his concept of single-mindedness had a lasting influence on the Japanese neo-Confucianists of the Tokugawa period.

Every major Korean neo-Confucianist shared Toegye's preoccupation with single-mindedness, which signalled new stress on praxis in the development of Korean neo-Confucianism: the fusion of the metaphysical and the physical is better brought about through action than speculation, important as theory might be. That was the point of Yulgok's integration of sincerity (sung) with single-mindedness. In this respect Korean neo-Confucianism made a break with the Cheng-Chu school of Chinese neo-Confucianism, which was overly speculative.
