퇴계 만년정론을 중심으로 본 퇴계와 고봉의 사단칠정논쟁

Abstract

This article focuses on Lee Whang(李滉; Toegye; 1501~1570) approving these of Gidaeseoung(奇大升; Gobong; 1527~1572) in last part of their four-seven debate, even though it is generally known that Gidaeseoung gave up Lee Whang. In fact, in the process of this debate, Lee Whang keeps on insisting that Sadan (four beginnings; 四端) is Ligibal(issuance of Li 理之發), though Chiljeong(seven emotions;七情) is Qigibal(issuance of Qi;氣之發). Gidaeseoung also referred to Ligibal and Qigibal, which is different from meaning of Lee Whang's mentioning. Gidaeseoung's mentioning Ligibal is the regulation of Chiljeong(七情之中節) which is same meaning of Sadan, Qigibal is irregulation of Chiljeong. By the way, in the last part of this debate, Gidaeseoung send Lee Whang equivocal conclusion that Sadan is Ligibal for needing to expand moral emotion, Chiljeong is Qigibal for needing to regulate general emotion which is apt to falling evil, on the other hand with not giving up previous these he insist that Sadan is only the regulation of Chiljeong. After Lee Whang receiving Gidaeseoung's this letter, he reply to Gidaeseoung that he has mistakable possibility in mentioning that especially sage's regulation of Chiljeong is not Ligibal. This implies to agrement to Gidaeseoung's these and being different from Lee Whang himself's previous these. It is called Treatise on Last Theory of Toegye which impacted on later scholar of Toegye's school.
