Yi T’oegye

Yi T'oegye, also known as Yi Hwang, was a prominent Korean scholar of the Joseon dynasty in the 16th century. He was a key figure in the development of Neo-Confucianism in Korea. T'oegye was known for his idealistic orientation and his contributions to theoretical Confucianism. He established private academies called s\u014fw\u014fn, which produced many eminent scholars, including himself and Yi I (Yulgok). Their distinct theories of the universe evolved into rival schools of thought, engaging in debates about the essential (yi) and existential/material (gi) nature of reality. These debates paralleled similar arguments in Chinese Neo-Confucianism and often had political implications.123
