Yi Hwang (Toegye) 退溪 李滉

1501–1570 · Joseon Korea

A Neo-Confucian philosopher of mid-Joseon Korea. He declined government posts dozens of times and opened an academy in his home village of Dosan to teach students. He is famous for the Ten Diagrams on Sage Learning, which he presented to the king, and for the Four-Seven Debate he carried on with Gi Daeseung. He saw the heart of learning as 'gyeong' (reverence): the practice of keeping the mind steadily awake.
