The Toegye School is a prominent school of thought in Korean Confucianism, founded by the scholar Toegye Yi Hwang in the 16th century. It emphasizes the importance of moral cultivation and the study of human nature, focusing on the relationship between the individual and the universe. The school played a significant role in shaping Korean intellectual and cultural life during the Joseon Dynasty. Toegye's teachings are often contrasted with those of the Yulgok School, founded by Yulgok Yi I, which emphasizes practical ethics and social engagement. The Toegye School's influence can still be seen in modern Korean education and philosophy, highlighting the enduring legacy of Confucian ideals in Korean society.
