One of the most notable topics, which has already become a familiar term for us, can be said to be the "Fourth Industrial Revolution." One of the characteristics of this Fourth Industrial Revolution is the emergence of artificial intelligence (AI). The aim of this thesis is to interpret artificial intelligence in conjunction with Li, the core philosophy of Toegye Yi Hwang, the integrator of the Neo- Confucianism in the Joseon Dynasty. Artificial intelligence is the main concept of creating computer programs or machines that can act, which can be regarded as intelligent if humans do. Toegye accepts Zhuxi s philosophy critically, while succeeding and developing it. Among them, Lidong (理動, Movement of Principle), Libal (理發, Issuance of Principle), and Lido (理到, Advent of Principle) are the key propositions. Toegye focused on Li s movement for the movement and calmness (動靜) that Zhuxi proposed in Lidong. Libal is to appreciate the issuance of Li by carefully examining the human nature of mind, which is to adhere to the good moral emotions of the human being. Lido emphasizes the meaning of Mulgyok (物格, Things Making Sense) in the method of knowing things. This thesis can be said to be one of the theories of Neo-Confucianism, which is hard and difficult in artificial intelligence society, to clearly explain the philosophical content of Li through researches and reasons. This thesis is to be written, despite the variety of application patterns that Li has, because it is judged that the researches in this field have still been insufficient so far. In particular, if we analyze Li, an important theory of Neo-Confucianism, from the perspective of Toegye and draw multiple models by establishing logic and theory, it can be seen that it will function well in the coming artificial intelligence era.
