Plato is the founder of Western objective idealism. His philosophical system is broad and profound, which has a great influence on his teaching thought. Plato believed that the world was composed of "idea world" and "phenomenon world". The phenomenon that every human being is exposed to is a kind of temporal and spatial phenomenon, but the real world is only a kind of temporal and spatial phenomenon.

Plato believed that all human knowledge comes from talent, which exists in human soul in a potential way. Therefore, cognition is not the feeling of the material world, but the memory of the conceptual world.

The purpose of teaching is to restore people's inherent knowledge. The teaching process is the process of the concept of "recall". In teaching, Plato attached importance to the general and general understanding, especially the cultivation of students' thinking ability, and believed that concepts and truth were the products of pure thinking.
