Yi Eon-jeok (Hoejae)
Also called: Hoejae
Neo-Confucian scholar who pioneered the primacy of li and influenced Yi Hwang; died in exile at Ganggye after the purge of 1547
Under Jungjong he debated the Supreme Ultimate with Jo Han-bo and set out a position putting li before qi, opening the way for Yi Hwang. Caught up in the Yangjaeyeok wall-poster affair of 1547, he was exiled to Ganggye in Pyeongan and died there. He is enshrined at Oksan Seowon in Gyeongju and is one of the Five Sages of the East honoured in the Confucian shrine.
